One capture/sanitization/observation boundary and stable identity/evidence model feed projections that are rebuildable within the retained evidence horizon. One typed query engine, one policy/replay runtime, one generated capability catalog, and one application use-case layer serve thin CLI, MCP, official API/SDK, hook, dashboard, saved-view, and lab adapters. + +**Tech Stack:** Rust workspace; standard local SQLite semantics through a storage trait, initially implemented with `rusqlite`, FTS5, and WAL; privacy-domain-scoped content-addressed local blobs; optional local embeddings; Axum HTTP + SSE; React + TypeScript; the dashboard bundler selected by an explicit Rsbuild-versus-Vite ADR; Sigma.js/Graphology for large topology graphs; ECharts for quantitative views; Canvas/WebGL + D3 scales for dense timelines; CodeMirror 6 for message/code/diff inspection. Remote libSQL is a future adapter, not part of the first V2 default. + +**Detailed execution plans:** [`tracedecay-v2/00-plan-set-index.md`](tracedecay-v2/00-plan-set-index.md) owns the per-crate, root-migration, frontend, dependency, PR-order, and cross-plan verification map. + +## Global Constraints + +- Local-first, single-user operation remains the default. No required network service or hosted database. +- “One brain” is a unified logical model and product, not one failure-prone monolithic database. +- Every semantic responsibility has one canonical owner and generated/shared contract. V2 does not preserve parallel session/LCM, detector, query, scope, policy, status, error, command, renderer-state, or transport business-logic implementations. +- Compatibility/anti-corruption adapters are time-bounded migration code with owners, parity tests, retirement gates, and deletion PRs; they cannot become a permanent second architecture. +- Extensibility uses versioned typed SPIs and capability manifests with safety/resource constraints. New providers, detectors, projectors, rankers, policies, tools, and renderers plug into canonical pipelines rather than creating new stores/query stacks. +- `All` is the default product scope. Projects are filters and ownership/privacy boundaries, not separate dashboard products. +- No flag-day migration. V2 runs beside V1, imports and shadows it, proves parity, cuts over by bounded context, and retains rollback. +- Sanitized observations are append-only and preserve all non-secret source semantics within their declared retention horizon. Secret spans are never copied into the observation; optional raw forensic retention is isolated/encrypted/short-lived. A non-content tombstone/provenance skeleton survives retention or deletion. +- Derived data is versioned, provenance-bearing, rebuildable within the retained evidence horizon, and never silently treated as canonical. +- Every relationship says how TraceDecay knows it: observed, provider-declared, user-declared, derived-exact, inferred, or heuristic. +- Historical views never reconstruct hidden chain-of-thought. They show only provider-exposed reasoning summaries, user-visible rationale, actions, and evidence. +- No secret-classified content enters FTS, vector indexes, facts, fixtures, exports, logs, or committed test corpora. +- Every cross-project response reports searched, skipped, unavailable, stale, truncated, and redacted coverage. +- `All` means the active TraceDecay profile by default. Additional profiles are federated only through explicit profile selection/collections and never mixed implicitly. +- Canonical provider transcripts live in a profile activity/session shard because a session may touch zero, one, or many projects. Project shards own scoped projections and locators, not duplicate canonical messages. +- Data migration and shadow parity are mandatory; stale live CLI/MCP/daemon/plugin protocols and obsolete tool names are not emulated after their domain cutover. Version mismatch fails with restart/update and the current replacement. +- V1 stores remain read-only from their domain's verified cutover until one full release of V2-default operation completes (the rollback/evidence window). Deletion is an explicit later operation, never part of migration. +- The plan PR contains only this master plan and its linked per-crate/frontend plan documents. Research exports remain untracked outside the repository. + +--- + +## 1. Executive Decision + +TraceDecay has accumulated the pieces of an agent intelligence system, but those pieces are organized as storage and transport islands. Code graph, sessions, LCM, memory, analytics, hints, automation, workflows, Git correlation, response handles, and dashboard plugins each have useful local capabilities, yet they cannot answer a single joined question such as: + +> Starting from this user request, what did the parent agent and its subagents see, infer, retrieve, decide, invoke, change, test, commit, encounter in GitHub, teach TraceDecay, and affect downstream—and how certain is every link? + +The redesign will make that question native. + +The selected strategy is a strangler rewrite around five foundations: + +1. **Canonical identity:** stable entities and aliases across providers, projects, worktrees, branches, sessions, messages, agents, code snapshots, symbols, facts, artifacts, and delivery systems. +2. **Immutable evidence:** observations, typed events, bitemporal relation assertions, provenance, confidence, sensitivity, and algorithm versions. +3. **Shared query platform:** one bounded `TraceQueryV1` AST and application-service layer used by every transport and UI. +4. **Unified investigation product:** one workbench with a global scope/time model, Brain, Explorer, Causal Timeline, domain workspaces, and deterministic replay labs. +5. **Convergence governance:** one owner/contract per concept, strict crate dependency direction, generated transport/client/catalog bindings, extension SPIs, architecture lint, complexity budgets, parity receipts, and mandatory retirement of superseded paths. + +The rewrite will not copy every current table into a larger database or place every entity in a giant force graph. It will preserve physical isolation and use purpose-specific views over one evidence model. + +## 2. Evidence Base + +### 2.1 Live system snapshot + +The audit was run on 2026-07-09/10 UTC from a clean worktree created from and repeatedly refreshed against `origin/master`; the publication base is `273f50c0372f063b97f4755563a3ded65ef324d5` at crate version 0.0.53. In addition to the 0.0.48 base through split-store consolidation PR #425, it includes accepted fixes for untracked branch graphs (#426), divergent session variants (#428), indexed consolidation-family lookup (#430), hook lifecycle quiescence (#432), conflict-safe registry reconstruction (#434), read-only search versus explicit FTS repair (#435), graph SQLite peer-checkpoint safety (#436), restart-safe retirement of applied consolidation inputs (#438), orphan-store truth derived from the registry-reconstruction diff (#439), and per-manifest isolation of registry reconstruction conflicts (#440), followed by release #437. Only draft plan PR #421 remained open at the publication refresh. Early store/analytics snapshots used installed TraceDecay 0.0.44; the final original planning probes used installed 0.0.47, and the reconciliation audit used installed 0.0.52 before the 0.0.53 source release merged, so every runtime observation remains version-labeled rather than being silently upgraded to newer source semantics. During research, the live store continued ingesting sessions, so counts are timestamped snapshot values rather than timeless constants. The direct `project_list` snapshots before and after the early rebase both reported 25 repositories; concurrent audits observed 28–29 searched/registered scopes, reinforcing the requirement that inventories carry a timestamp, tool/runtime identity, catalog generation, runtime version, and watermark rather than presenting a drifting count as timeless. + +| Signal | Observed evidence | Design consequence | +|---|---:|---| +| Registered repositories returned by the project-list snapshot | 25 | `All` must be a first-class scope with shard pruning and partial coverage. | +| Final doctor registry/watcher snapshot | 29 active watched roots; 179 profile-sharded registry entries; 12 orphan manifests; one stale missing-worktree row | Registry, watcher, store-manifest, and live-root inventory need one reconciled view with explicit populations, not separate timeless counts. | +| TraceDecay code graph | 38,510 selected-shard nodes, 74,602 edges, and 987 files in the final identity-conflict/storage receipt | Graph scale is locally tractable, but cross-project rendering requires clustering and level of detail. | +| Locally tracked TraceDecay branch graph stores | 14, commonly about 140–150 MB each in the inspected branch list | A physical database per branch multiplies nearly identical state; V2 needs immutable packed snapshots plus bounded overlays and ref pointers. | +| All-provider LCM native-message rows (V1 table named `raw`) | 418,346 at the final supported status snapshot | V2 sanitizes before persistence; timeline/search/export must be cursor-based, virtualized, and server-aggregated. | +| LCM summary nodes | 1,541 | Summaries are derived lineage artifacts, not a separate source of truth. | +| LCM estimated store tokens | 12,978,427 | Query budgets, payload externalization, and visible truncation are product requirements. | +| LCM compression ratio | 9.4:1 | Compression health is useful, but must link to exact source coverage and replay. | +| Hook calls | 59,618 | Hooks are a high-volume event stream and need cheap append paths. | +| All-scope analytics usage page | 10,000 capped events; 102 defined tools; 43 used tools at the frozen probe | Aggregate adoption and raw-event coverage must be separate: a capped event page cannot be presented as the whole population. | +| Installed MCP-equivalent TraceDecay tool names | 102 at the older frozen compatibility inventory; plan 21's generated audit at commit `9f7a1108` is the arbiter and counts 104 source MCP tool definitions with 103 installed at 0.0.47 | Capability exists but is hard to discover and scattered; one generated catalog must own use-case IDs and every transport binding. | +| Hints emitted | 1,182 | Hint policy needs replay, explanation, and outcome attribution. | +| Hint outcomes measured as acted | 3 | The current feedback loop is mostly unresolved and cannot support confident optimization. | +| Analytics event sample | merged PR #424 moves exact totals/tool/hint sections to DB-side aggregates and adds >10,000-event coverage while bounded raw-event lists remain separate | Raw lists need stable pagination and explicit caps; exact aggregates must execute before sampling, declare denominator/horizon/watermark, and never render a tail sample as the whole. | +| Analytics `message_count` under `--all` | 0 while LCM contained 388k+ rows | Missing denominators must be `unknown`, not misleading zero ratios. | +| Managed skills | 10 active | Skills, automation runs, adoption, and evidence belong in one observable lifecycle. | +| Automation-lane coverage | selected shard reports `automation_files=0`, while the conflicting legacy shard reports 3,470; automation config/runs fail at identity resolution before a legal lane can be selected | Profile/project scope and skipped/conflicting lanes must be explicit; zero in one selected shard is not proof that no automation evidence exists. | +| Memory/fact scope drift | an early project memory-status view showed 0 facts; the final selected shard had 17 while the preserved legacy shard had 129 | Memory scope and branch/project/profile/store ownership are currently easy to misread; zero in one lane is not a global absence claim. | +| Early fact-store search | failed with `file is not a database`; the final direct selected-shard MCP path worked while worktree CLI resolution still refused the identity split | Store routing, corruption isolation, partial results, and repair evidence must be visible per domain and resolved store. | +| Doctor on the same checkout | reported active DB integrity as healthy | Every response must identify the exact store/shard/runtime used; “healthy” cannot be ambiguous. | +| Project-list response | truncated without a retrieval handle | Structured APIs must paginate before renderer-level truncation. | + +The final selected-versus-legacy refusal is a concrete migration fixture, not an abstract warning. The selected shard `proj_ceaa713e40fef2b2` was healthy with 38,510 nodes, 987 files, 17 facts, 2,003 sessions, 432,790 messages, 419,887 LCM rows, 14 branch stores, zero automation files, five payload files, and three response files. The preserved legacy shard `proj_b4a8bbe4953823c4` was also healthy with 36,596 nodes, 989 files, 129 facts, 4,129 sessions, 603,866 messages, 592,594 LCM rows, 197 branch stores, 3,470 automation files, 1,839 payload files, and four response files. Neither is a disposable duplicate. Until the #425 workflow or its V2 successor freezes, backs up, reconciles, verifies, and atomically cuts the identity markers over, every affected semantic tool must return both candidates and typed unavailable coverage rather than initialize, guess, or report a misleading empty lane. + +### 2.2 Code-health snapshot + +`tracedecay tool health --args '{"details":true}'` reported: + +- Quality signal: **6,979 / 10,000** across 987 files. +- Acyclicity: **0.4769**, with 2,619 edges in nontrivial strongly connected components. +- Equality: **0.3713**, with complexity Gini **0.6287**. +- Depth: **1.0**; modularity: **1.0**; redundancy: **0.94**; coverage discipline: **1.0**. +- Static test attribution around 45%, leaving thousands of reachable but unattributed functions. +- High fan-in: `src/global_db.rs`, `src/storage.rs`, `src/agents/mod.rs`. +- High fan-out: `src/mcp/server.rs` and MCP handler routers. +- Major production files exceed 3,000–4,700 lines, including `src/global_db.rs`, `src/mcp/tools/definitions.rs`, `src/sessions/lcm/query.rs`, `src/mcp/server.rs`, and session/analysis handlers. +- `McpServer` and `DashboardState` are broad composition structures with 38 and 20 fields respectively. + +These are not merely file-size problems. They show that persistence, application logic, transport rendering, project routing, and policy decisions are not separated by stable interfaces. + +### 2.3 User-intent evolution from LCM + +The supported LCM export recovered tens of thousands of chronological `role=user` rows across more than one thousand sessions between 2026-06-28 and 2026-07-09. A separate human-authored subset is required because Claude protocol tool-result rows are also stored as `role=user`. + +The evolution is coherent: + +1. **Operational foundation:** daemon visibility, telemetry, background curation, skills, memory, and automation must be continuously runnable rather than manual curiosities. +2. **Self-introspection:** TraceDecay must inspect its own usage across projects and transcripts, measure whether agents use the right tools, and improve from real evidence. +3. **Finish-the-loop automation:** work should progress from discovery through code, verification, PR, merge, release, local upgrade, and post-release health, with explicit state at every step. +4. **Lossless agent history:** sessions, tool calls, reasoning summaries, goals, subagents, files, Git, and outcomes must remain queryable without relying on topical snippets. +5. **Adaptive guidance:** hints, skills, memory, and tool discovery should be contextual, quiet when irrelevant, measurable, explainable, and testable against historical messages. +6. **One global Brain:** the dashboard should stop reflecting storage silos and expose TraceDecay as one cross-project system with powerful visual investigation and replay interfaces. + +Repeated durable requirements: + +- Dogfood TraceDecay on TraceDecay using real work, not synthetic demonstrations alone. +- Preserve complete inspectable history and exact technical evidence. +- Navigate globally, then narrow to project/worktree/branch/session/agent/time. +- Connect intent, agent behavior, code, delivery, memory, policy, and outcome. +- Measure whether self-improvement mechanisms are actually adopted and helpful. +- Make every automation and policy decision debuggable and replayable. + +### 2.4 Research limitation that becomes a product requirement + +The current public LCM surface cannot enumerate every session or perform a match-all role query. `lcm_grep` requires a text query, caps results at 100, and can disclose capped sessions without offering a complete cursor. The research export therefore had to recursively bisect time windows, union token-prefix searches, discover session IDs, then page `lcm_load_session` by stable store cursor. + +V2 must add: + +- `list_sessions(scope, role, provider, time, cursor)`. +- `list_messages(scope, roles, kinds, provider, time, cursor)` with no text predicate. +- Exact enumeration/export of all authorized retained sanitized session records for JSONL/Parquet with manifest, counts, hashes, privacy coverage, and redaction report; provider raw source remains locatable but is not copied when secret/retention policy forbids it. +- Explicit separation of human-authored messages from provider protocol rows. +- A snapshot watermark so an export can prove completeness while live ingest continues. + +The private research artifact set is stored outside Git at `/fast/tracedecay-redesign-research/`: 34,344 chronological native `role=user` records in `user-messages-chronological.jsonl` (SHA-256 `edfe67d6baf9fd87faa9fd49c443a777bbb838c3eb36a79106c06f18a161baff`), a 9,980-record best-effort human-authored derivation in `human-messages-chronological.jsonl` (SHA-256 `5afb40d25f3fc43b86d620b25daea94a0b4f33ffc4421b5bb20b6a550b8c3bcb`), `manifest.json` with hashes/counts/caveats, and `intent-evolution.md`. The directory is mode `0700` and every corpus, manifest, report, and helper file is mode `0600`. Each row's `content_hash` is SHA-256 of retained sanitized UTF-8 content, never a residual pre-redaction fingerprint. The broad corpus came from supported TraceDecay surfaces; the active parent contributes 39 direct prompts with explicit `codex_rollout_raw_fallback` provenance—the original 28 plus 11 reconciliation prompts—and excludes three internal goal/environment context envelopes. The final user-message cutoff is 2026-07-10 20:26:39.847 UTC. + +### 2.5 Git-tool discovery failure is product evidence + +The redesign investigation itself exposed a failure in TraceDecay's guidance loop. The request explicitly concerned `master`, a new worktree, open PRs, branches, and prior implementation intent. The first pass still reached for generic shell/GitHub inspection and only used TraceDecay's semantic Git tools after the user challenged the omission. No hook hint routed the task toward the existing branch, PR-context, changelog, correlated-session, or workflow tools. + +After correction, the TraceDecay Git surface added useful evidence: + +- `branch_list` exposed the locally tracked branch graph inventory and its fallback/tracking state. +- `pr_context` summarized changed symbols and architectural impact for every open PR branch. +- `changelog` exposed commit-level semantic history, but returned a much broader merge-base range than the live GitHub changed-file view for some branches. +- On PR #410, `pr_context` agreed on 16 directly changed files and the merge base, yet labeled thousands of transitive/file-level symbols as modified and emitted an extremely broad affected-test list. Direct diff facts, dependency impact, candidate tests, and low-confidence module fan-out need separate sections, counts, evidence, and caps. +- `sessions_for` recovered correlated implementation sessions for the Hermes migration branch, but none for the legacy-store branch or the newly active PR #410 branch. +- `workflows` found no correlated workflow records for those branches. Absence must render as named capture/index/coverage state, not proof that no agent or workflow participated. +- The final refresh discovered PR #423 and correctly attempted `tracedecay tool pr_context` first, but both the explicit redesign worktree and explicit repository root failed before Git analysis with the preserved selected-versus-legacy identity cutover conflict. After #423 and Hermes profile consolidation #407 merged, the same TraceDecay-first attempt for new analytics PR #424 still failed on that conflict and required `gh pr view` plus bounded Git diff. This proves capability discovery alone is insufficient: a semantic Git tool must either route through an authorized healthy identity, return both candidates with a retryable exact selector, or produce a structured partial result that preserves the remote/Git facts it can still answer; an unrelated store-identity conflict must not erase all PR context. + +The 0.0.52 publication re-audit exposed two additional routing classes. FM-112: an explicit linked-worktree selector resolved to the base checkout, semantic grep scanned zero files, and read rejected a file inside the requested worktree as escaping the incorrectly selected root. The CLI with an explicit project path succeeded. In the same worktree, `sessions_for` returned zero while message search recovered the prior authorized actor `agent-abf181084b74689f2`. FM-113: a later explicit CLI read selected an empty/conflicting eligible identity while `doctor` in the same CWD called legacy store `proj_a5b3d7e3ebe14ca7` healthy with no identity drift; the same read subsequently succeeded without exposing the catalog/identity transition that changed the answer. Code, Git, transcript, workflow, doctor, CLI, and MCP tools therefore cannot each reinterpret a repository/worktree selector independently, turn disagreement into empty/healthy, or change identities without a durable shared scope-resolution receipt. + +Final 0.0.53 verification added FM-115–FM-117. An explicit worktree sync identified the live long-running daemon as the conflicting sync-lock owner and suggested lock deletion while read/status still called the index 1,339 minutes/22 hours stale and “refresh in progress” without an operation ID. A piped `tracedecay status` ignored `TERM=dumb` and `NO_COLOR=1` and emitted a large true-color half-block dashboard. Finally, staged `commit_context` aborted on an optional test-annotation row whose file was not a valid SQLite database instead of returning healthy Git/diff context with partial enrichment coverage. V2 therefore makes refresh an observable fenced operation rather than a daemon-lifetime file lock, makes interactive TUI rendering an explicit TTY capability while plain/JSON status remains bounded and deterministic, and isolates corrupt optional indexes so semantic Git tools retain their primary answer. + +This is not merely operator error. V2 must make the right capability discoverable at the moment of need, explain when live remote state and local semantic state answer different questions, and measure when the user has to correct tool selection. Required consequences: + +- A Git-intent classifier for branch, worktree, commit, diff, PR, review, checks, release, blame, and historical-intent requests. +- A generated tool catalog with compact task-to-tool routing hints, including when live GitHub state must be refreshed before semantic analysis. +- Reconciliation metadata: local ref/merge base/indexed commit, remote head/fetched-at, fallback state, changed-file universe, and named disagreement between remote and semantic results. +- Typed fallback chaining: preserve the attempted capability, explicit scope, selected/legacy candidate IDs, unavailable semantic domains, safe Git/remote fallback result, and one retrieval/operation anchor instead of forcing the agent to restart the investigation manually. +- One canonical scope-resolution receipt shared by code, Git, session, workflow, memory, and fact tools: requested path, canonical repository, exact worktree/branch/snapshot, resolved root, index commit/watermark, searched population, and named disagreement. +- Semantic Git results that distinguish `directly_changed`, `structurally_impacted`, `candidate_test`, and `context_only`; never describe fan-out expansion as a direct modification. +- A `missed_capability` outcome when a relevant tool was neither suggested nor used, and a `human_correction` event when the user redirects the workflow. +- Hint evaluation that credits useful silence but penalizes missing a high-confidence, high-value repository capability. + +### 2.6 Current-master accepted changes + +The plan treats merged rows below as required base semantics at publication base `273f50c0`; rows explicitly marked open are incoming constraints that execution must reconcile before touching their seam. Only draft plan PR #421 remained open at the publication audit. Implementation must not rediscover or regress accepted behavior, and must not assume an open input has merged until the execution-slice refresh proves it: + +| PR/status | Behavior | V2 consequence | +|---|---|---| +| `#405` merged — legacy identity-store adoption | Expands legacy identity-store discovery/adoption and lifecycle migration coverage. | Preserve aliases and adoption receipts in the catalog migration; never create a second canonical project because a legacy directory or hash moved. Import resolver fixtures into V2 identity/backfill conformance tests. | +| `#406` merged — corrupt database recovery sets | Preserves corrupt database families instead of overwriting/destroying forensic recovery inputs. | Detect non-SQLite/corrupt/torn stores before open, quarantine the whole WAL/SHM/database family, preserve a signed recovery set, keep healthy shards available, and make operation-specific repair plan/start/recover receipts auditable. | +| `#412` merged — safe daemon drain during upgrades | Serializes update/upgrade/doctor lifecycle, drains in-flight requests/background writers, checkpoints after writer stop, and preserves systemd/launchd stopped/disabled/masked state. | V2 needs one fenced lifecycle coordinator across daemon, store, watcher, updater, doctor, migration, backup, and service manager; no environment bypass or unconditional restart. | +| `#407` merged — Hermes user profile | Consolidates Hermes onto the user's active profile, removes Hermes-specific bridges/config/inventory, and migrates legacy Hermes project identities/facts. | Profile is the durable isolation boundary; Hermes is an actor/automation/tool identity inside it, not a parallel product silo. Plan 24 ports or improves Hermes Kanban into a native TraceDecay product rather than restoring a Hermes task service. Historical Hermes data remains import evidence, and Hermes may separately be an execution host through the common worker protocol. Migration must retain fact provenance and record moved identities without copying content across privacy domains silently. | +| `#410` merged — collapse copied subagent prompts | Preserves native transcript rows, but adds query-time parent-representative dedupe and `direct_user`/`subagent`/`tool_result` filters across message search, LCM, CLI, and MCP. | V2 must preserve sanitized native rows and explicit message-origin classification while offering representative/human views with hidden-copy counts and provenance. Import its eight-child regression corpus and never make UI dedupe an irreversible ingest rule. | +| `#411` merged — foreign-installation skills are info | Aligns doctor with the remove path so it does not prescribe `update` for project skill packages this installation refuses to delete. | Health/remediation uses one shared typed predicate with the command precondition; every finding declares owner, severity, safe action, whether automation can execute it, and proof that the advertised remediation is actually applicable. | +| `#413` merged — release v0.0.46; `#416` merged — release v0.0.47 | Packages the audited storage/runtime/session/doctor/tool fixes into published release versions. | Record actual merge/release/catalog/schema versions in compatibility/import manifests; architecture must not depend on release-PR file layout or infer availability from source only. | +| `#414` merged — `tracedecay_move_symbol` with impact report | Adds a semantic Git/code mutation capability after hardening against data loss and span defects. | Import its historical effect/safety/dry-run/receipt evidence, then expose operation-specific V2 edit inspect/commit/recovery through generated API/CLI/MCP parity, Git-intent routing, and current-versus-live-ref conformance; no tool may bypass sanitizer/scope/application authorization. | +| `#415` merged — release PR integrity guard | Adds CI enforcement around release PR integrity. | Release/publication is a generated-contract transaction: crate/package/API/SDK/catalog/schema/version artifacts must be mutually consistent and partial publication blocks. | +| `#417` merged — doctor identity split visibility | Surfaces identity split conflicts rather than hiding competing legacy/selected stores. | Identity/store reconciliation is a first-class inspect/plan/start/recover application workflow; status names both authorities, evidence, serving refusal, and exact next action without destructive guessing. Import the live convergence-probe fixture from plan 19. | +| `#418` merged — release v0.0.48 | Packages merged move-symbol, foreign-skill ownership, analytics, and split-store consolidation changes at merge `3567e31e`. | Record source commit, package version, tag/package/catalog/schema digests, and partial-publication state in compatibility manifests; source merge still does not prove a particular installed host was upgraded. | +| `#427`/`#429`/`#431`/`#433` merged — releases v0.0.49 through v0.0.52 | Package the accepted consolidation, hook-lifecycle, registry, and related fixes through tag commit `09080e80`; publication head later advanced through #438 to `3bea5ec7`. | Treat release PRs as versioned publication evidence only; bind installed-runtime observations to their own reported version/catalog/schema digests. | +| `#419` merged — race-safe `move_symbol` writes | Rejects destination symlink escapes and same-file/hard-link aliases, revalidates both source/destination snapshots, uses atomic sibling renames, and avoids clobbering concurrent rollback edits. | Every V2 edit command carries exact source/destination identities and versions, revalidates immediately before commit, uses race-safe filesystem primitives, preserves legal in-project symlinks, and records rollback conflicts rather than overwriting concurrent work. | +| `#420` merged — proxy MCP before opening local stores | Chooses the managed-daemon proxy before resolving/opening local stores; reconnects one daemon connection per request across socket/PID replacement without replaying writes; schema changes still require a new host MCP session/tools list. | Root composition resolves proxy/local authority before any store side effect, delegates config-gated init to the daemon, never replays an uncertain write, and advertises typed reconnect-versus-restart/tool-catalog-refresh requirements. | +| `#422` merged — refresh MCP tools after daemon generation change | Negotiates `tools.listChanged`, carries stable client-instance and catalog-version metadata across per-request proxy connections, notifies once per client per daemon generation including same-version restarts, treats initialize/tools-list as current, bounds dedupe without eviction, and distinguishes stale host from stale daemon. | Catalog generation is a first-class handshake/status value. Long-lived hosts refresh without duplicate notices, forged/unbounded client IDs cannot exhaust state, fresh list/initialize suppresses redundant delivery, and schema incompatibility still produces explicit restart/update rather than silent fallback. | +| `#423` merged — preserve FTS5 relevance direction | Replaces `1/(1+abs(rank))`, which reverses negated FTS5 BM25 magnitude, with a bounded direction-preserving transform; adds a real exact operational-evidence-vs-unrelated-V2-facts fixture plus rare-term, once-per-explicit-search counter, context-enrichment, and analytics assertions. | Treat the fix as accepted-base behavior and retain the pre-fix failure as a hard retrieval regression. Ranking contracts must name native score direction/scale, normalize monotonically, separate access/retrieval telemetry from relevance, prevent rich-get-richer feedback, and evaluate exact operational evidence against plausible high-trust plan/memory distractors across CLI/MCP/context surfaces. | +| `#424` merged — aggregate analytics sections before sampling | Computes exact event totals and DB-side tool/hint rollups before rendering, removes the generic latest-10,000 cap from those aggregates, adds project/time indexes, and tests a >10,000-event window. | Treat aggregate-before-sample as accepted-base behavior: registered V2 metrics must aggregate over their declared population before presentation caps, keep bounded raw-event drill-down separate, expose cap/denominator/watermark state, and share one query/view across MCP/dashboard/API. | +| `#425` merged — explicit split-store consolidation | Adds the historical V1 offline consolidation planning/execution workflow (commands currently named plan/apply) for two nonempty profile shards: canonical cross-platform store paths, frozen SQLite families, unsupported-holder refusal, write reservations, dual backup, deterministic confirmation under lock, restartable ledger/staging states, explicit table merge/rebuild/reject dispositions, collision accounting, remapped LCM source-edge preservation, exhaustive verification, marker/registry cutover only after proof, and doctor recovery. Final head `d3bb28b57bef6f7fa513ff4b0645ce5e31a97872` adds holder identity by file/inode on top of `12182510` canonical macOS paths and `82cfa9b9` LCM-edge remapping; merge is `de3d05dc8f7f75028d8721b7d65c487459c5f170`. Linux/macOS/build/format/clippy and other checks passed; the repository's existing Windows-shard failures remained red on both #425 and release #418 and are retained as base failures, not waived evidence. | Treat it as accepted V1 anti-corruption behavior and generalize it rather than creating another merger: V2 exposes operation-specific consolidation inspect/plan/start; both inputs remain immutable through planning/verification; holder identity is path-plus-file identity; every table and derived edge has a disposition; privacy scans and backup manifests gate publication; cutover is one fenced identity transaction; recovery never guesses from path or newest mtime. | +| `#426` merged — recover untracked branch graphs | Recovers branch graph databases whose metadata was absent instead of omitting or garbage-collecting the only branch graph evidence. | Branch artifacts are inventoried by verified file identity and content fingerprint as well as metadata; reconstruction is explicit, resumable, and preserves unmatched databases until ownership is proven (FM-104). | +| `#428` merged — preserve divergent session variants | Distinguishes exact duplicate sessions from same-ID sessions whose content diverges across consolidation inputs, preserves both divergent variants, and remaps dependent rows. | Identity reconciliation must compare canonical content/provenance, allocate stable variant identities when histories differ, and remap every dependent message, LCM, summary, and source edge rather than choosing one row by ID (FM-105). | +| `#430` merged — index consolidation-family lookups | Replaces repeated recursive JSON/source scans with materialized indexed lookup tables during consolidation and verifies production SQL plans. | Every migration family lookup has an owned normalized index, bounded complexity, query-plan regression tests, and restartable materialization; scale cannot depend on recursively rescanning manifests or source rows (FM-106). | +| `#432` merged — hooks honor lifecycle quiescence | Requires hooks to acquire the lifecycle lease before startup/config/store work, drains provider input while quiesced, and avoids agent/plugin installation side effects in the exclusive maintenance window. | Every capture ingress, including short-lived host hooks, participates in the same cross-process fence before composition; quiescence is a typed non-ingest outcome, never a hidden local-store fallback (FM-107). | +| `#434` merged — conflict-safe registry reconstruction | Classifies eligible manifests, refuses alias/path ownership conflicts, reconstructs registry state transactionally under lifecycle ownership, and leaves blocked evidence for doctor instead of resurrecting stale owners. | Catalog recovery is an idempotent proof workflow: no path/alias theft, no retired-manifest resurrection, no partial publication, and no inferred canonical owner from recency alone (FM-108). | +| `#435` merged — keep FTS repair out of search reads | Separates FTS-only damage from whole-database corruption and prevents ordinary search from mutating or repairing the index. | Query paths are side-effect free and return typed degraded coverage; explicit maintenance owns diagnosis, fencing, repair, verification, and receipts (FM-109). | +| `#436` merged — disable graph mmap across peer checkpoints | Disables graph SQLite memory mapping where peer processes can checkpoint and replace pages, covering mixed-page checkpoint behavior. | All peer-opened graph connections use compatible no-mmap safety settings until a generation protocol proves immutable mapping; checkpoint/consolidation tests include mixed page sizes and concurrent holders (FM-110). | +| `#437` merged — release v0.0.53 | Publication-only release merged as `273f50c0` after #439/#440 and packages their accepted behavior without adding a new architecture authority. | Bind source/package/tag/catalog/schema digests and checks to the release receipt; never infer that the locally installed runtime upgraded merely because the source release merged. | +| `#438` merged — restart-safe applied-manifest retirement | Validates and transactionally retires only proven schema-2 `Applied` source/target manifest owners under an exclusive lifecycle capability while leaving original shard data untouched and the destination canonical; final head `4f7b2b2c`, merge `3bea5ec7`. | Import restart-safe retirement as accepted anti-corruption behavior: retries are idempotent, ambiguous ownership fails closed with doctor evidence, registry rows and manifests change atomically, and V2 preserves the exact applied-ledger/retirement receipt (FM-111). | +| `#439` merged — derive orphan stores from registry reconstruction | Reuses the read-only registry-reconstruction preflight to count only manifests actually missing project/alias/store/scope/artifact rows, replacing incomplete token-accounting/path proxies; final head `de55e376`, merge `974d423b`. | Doctor, health, migration, and repair share one per-manifest typed diff and population. Complete registry rows never produce an orphan warning; a reported orphan links the exact missing rows and reconstruction plan (FM-114). | +| `#440` merged — isolate registry diff conflicts | Independently preflights each eligible reconstruction plan so one conflicting manifest does not hide missing rows in unrelated manifests; final head `7a56db8e`, merge `0dd1fd7d`. | Preserve each conflict, continue classifying every unrelated manifest, and expose per-manifest reconstruction/detection receipts through the shared catalog/doctor truth (FM-114). | + +PR `#409` was closed without merge and superseded by release PRs `#413`/`#416`; PRs #418, #425–#440 listed as merged above are accepted history where applicable.

[`tracedecay-v2/14-historical-failure-regression-matrix.md`](tracedecay-v2/14-historical-failure-regression-matrix.md) owns exact anchors and regression disposition. The recurring classes that shape V2 are: + +| Historical failure pattern | Representative evidence | Required V2 invariant | +|---|---|---| +| Store damage under disk-full/process death | Live graph DB became non-SQLite data;

#344 naming; #368 optional discovery; #400 Cursor showed only `graph`; this plan missed Git tools | Generated catalog and bindings, host capability handshake, one current name, high-confidence contextual routing, availability/fallback explanation, missed-capability feedback. | +| Doctor false positives and impossible remediation | Stale degraded Cursor logs #316; read-only mismatch #370; foreign-skill nag #411 | Findings and commands share predicates; health names exact store/owner/runtime; informational drift is not warning; every repair has an operation-specific inspect-or-plan, precondition, authorized start, and receipt. | +| Automation/self-improvement unsafe or low-value output | #295 output hardening; #338 retries/autonomy; #359 paraphrase dedupe | Evidence-bounded candidates, deterministic validation/policy, autonomous versioned effect/use/outcome/revision/recovery lineage, idempotent jobs, explicit autonomy configuration, and no per-item approval queue or unrecorded self-modification. | +| Memory corruption, scope, and extraction errors | #349 long fact mangling;

release/asset/drift fixes #310–#313; branding #400 | Generated host manifests, schema conformance, installed-version/source identity, transactional install/update, current capability handshake, actionable failure without stale-client fallback. | +| Flaky/order-dependent/cross-platform tests | Windows/env/global-state/watcher/timeout fixes #204/#207/#255/#283/#285/#326/#334/#351/#393/#394; current libtest-only backfill failure; final merged-#424 CI run had all five Windows shards fail, with shard 1 exposing an unavailable `tracedecay_ast_grep_rewrite` hint route, lifecycle lock error 33, Hermes path-string mismatch, and a Linux/macOS-only service-install path exercised by a Windows update test (fresh run evidence, not attributed causally to #424's diff) | No process-global mutable test state, hermetic clocks/env/ports/stores, generated platform capability/route matrix, normalized path identities, typed lock/service support, nextest/libtest contract, deterministic shutdown, platform matrix, and failure-class quarantine rather than retries as proof. | +| Observability without denominators or retrieval handles | Empty analytics message count, 10k cap, unresolved hint outcomes, truncated project list | Every metric declares population, horizon, cap, source watermark, and unknown state; every truncation returns stable cursor/export/retrieval anchor. | + +Compatibility lesson: non-disposable on-disk evidence must be migrated and retained for rollback, but V2 does **not** emulate stale running MCP/daemon/plugin clients or guess obsolete tool names. Protocol/catalog mismatch fails with an explicit restart/update/current replacement. Shadow adapters exist only inside the bounded migration and disappear at domain cutover. + +### 2.8 Message-search quality probe + +A small supported-surface replay compared exact, paraphrased, conceptual, and misspelled queries with `catch_up=false` so the new query would not immediately index itself. It is diagnostic evidence, not a statistically complete benchmark: + +| Query class | Observed behavior | Design consequence | +|---|---|---| +| Exact rare phrase: disk-full/non-SQLite graph corruption | Correct human issue was returned, but after a prior tool command that contained the query text and a copied assistant delegation. | Penalize query/tool self-echo and copied protocol/delegation rows; group by source issue/session and prefer direct human/native evidence. | +| Paraphrase: volume ran out of space during indexing | Returned many topically related disk/build/cache failures, but the exact graph-store corruption case did not reach the top ten. | Lexical recall is useful but intent precision is weak; evaluate semantic/entity/reranking stages against labeled paraphrases. | +| Exact doctor/foreign-skill/remediation query | Found the correct issue/delegation/user rows at the top, plus implementation/review copies. | Preserve exact phrase/BM25 strength; representative clustering and origin/kind filters must remove duplicate workflow noise without losing sanitized-native expansion. | +| Paraphrased impossible-remediation query | Found implementation and review traffic, but mixed the exact issue with unrelated health/skill sessions. | Use entity/event/PR/session anchors and intent-aware reranking, not embeddings alone. | +| Conceptual nearby-agent/duplicate-work query | Found useful shared-worktree and parallel-agent cases, but also repeated identical results copied across sessions. | Add agent/work-claim graph retrieval, duplicate clusters, session diversity, and deliberate-redundancy labels. | +| Misspelled hint/subagent query | Found the current exact misspelled request, but this does not prove general typo tolerance. | Add character n-gram/fuzzy retrieval and a typo corpus; never infer quality from one self-match. | + +Current message search is therefore useful for rare exact terms and high-recall forensic discovery, but not yet a reliable “best contextual answer” layer. V2 must benchmark a composed retrieval stack—lexical phrase/BM25, character fuzzy, entities, event/Git/agent graph, optional local dense representations, recency, duplicate clustering, and optional local reranking—then select the smallest stack that improves labeled metrics and latency. Embeddings are a candidate component, not a default claim of quality. + +The final live audit made the temporal failure concrete. Broad all-registered searches returned 81K–311K semantic payloads behind expiring response handles and were frequently dominated by tool definitions/calls, current-query echoes, generated inventories, and copied session rows. TraceDecay context found one logical parent message replicated under twelve session/store IDs. More importantly, a retained `memory-ranking-supersession` fixture proves an obsolete exact “use npm” fact can still outrank the newer “use pnpm” correction; current message/LCM search has no general authority, correction, contradiction, supersession, or valid-time resolver. Current `message_search` is FTS/BM25 plus filters/downranking, while `lcm_grep` has distinct raw/summary and relevance/hybrid/recency semantics; raw BM25 scores are also compared across independent project shards without a shared calibration guarantee. + +V2 therefore separates immutable message occurrences, evidence-backed logical-copy clusters, summary DAGs with exact source horizons, and temporal assertions with typed `corrects`/`replaces`/`contradicts`/`revokes` relations. Query mode is explicit: current, historical as-of, evolution, or forensic. Recency is an explained bounded feature, never a truth rule; direct human corrections, Git/check/command evidence, scope, validity, and authority decide current state, while uncertain conflicts expose both sides. Before promotion, at least 500 real query episodes and 5,000 human-grounded judgments span projects/providers, exact IDs, paraphrases, copies, summaries, corrections, cross-project work, no-answer/partial states, and task-context pollution. The source audit, twelve seed regressions, qrel schema, metrics, Search Quality Lab extension (folded into that lab, not a separate Search Lab), and cutover live in [`tracedecay-v2/23-session-lcm-temporal-retrieval-and-evaluation.md`](tracedecay-v2/23-session-lcm-temporal-retrieval-and-evaluation.md). + +### 2.9 Cross-project, store, session, and code-graph scope probe + +The Rspack/Rsbuild/React Router project family exposed a systemic failure rather than one missing search feature. In `session:019f42c9-623a-7cc0-95c1-f073eaa05a4d`, an agent concluded that Rsbuild/Rspack were not registered and fell back to installed packages. The user corrected this in `session:019f4323-f569-74c0-9988-ea3851d14fd7`: the projects existed, but the initial project list capped at 25 and `project_search "rsbuild rspack"` required one contiguous substring. `session:019f4325-57ef-7a53-b6a0-5c583c759301` isolated the single-`LIKE` root cause. Other historical cases include first-CWD Claude attribution, active-base-checkout PR/graph context when another worktree was intended, provider `project_key` acting as a public session boundary, missing-code-index hints suppressing healthy session/memory capabilities, stale/duplicate registry stores, and doctor reporting local/global scope inconsistently. + +The supported surface currently compounds these problems: `message_search(project_scope="all_registered")` can return a stable session ID from another project, while `lcm_load_session` is active-project-only and rejects a project selector. A result that cannot be expanded exactly is not a usable global search contract. + +V2 therefore has one typed scope plane across API, CLI, MCP, dashboard, hooks, and SDKs. Explicit repository/path/worktree/ref/PR/session targets never fall back to the active project. Provider keys and paths remain aliases/provenance; profile activity owns canonical session discovery, while project shards own scoped code/knowledge/delivery projections. Every federated response reports exact repository/worktree/ref/snapshot, searched/skipped/unavailable/stale/redacted coverage, rank/source evidence, and a location-independent retrieval reference. The complete architecture, Rspack/Rsbuild/React Router regression corpus, transport ergonomics, and implementation slices live in [`tracedecay-v2/16-cross-project-repository-worktree-scope.md`](tracedecay-v2/16-cross-project-repository-worktree-scope.md). + +### 2.10 Secret/redaction architecture probe + +TraceDecay has redaction components, but current behavior is fragmented and not a system guarantee. `src/sessions/lcm/raw.rs` can redact API-key assignments, bearer tokens, passwords, private keys, and sensitive JSON keys before LCM/session FTS projection, yet `ingest_config` defaults `sensitive_patterns_enabled` to `false`; production providers do not establish one mandatory policy. `src/memory/hygiene.rs` separately rejects secret-like fact content, but not every tag/entity/source/metadata field or V1 backfill. Provider/tool/session/hook/summary paths, response handles, backups, dashboard raw routes, logs/analytics, and already-derived FTS/vector/cache generations lack one complete enforcement and repair boundary. LCM status also reports `redaction.enabled` when any lossy row exists rather than whether protection is configured and coverage-complete. + +The current planning corpus added a practical scanner lesson: four marker-only private-key matches were conservatively removed, while a permissive authenticated-URL scan over serialized JSON produced a cross-field false positive that disappeared when values were parsed and scanned independently. The plan set and sanitized private corpus then passed `gitleaks 8.30.1` with zero findings. This does not prove live TraceDecay stores are clean; no supported whole-profile retroactive audit currently exists. + +V2 therefore has one mandatory, versioned, parse-before-scan sanitizer and taint-state contract before every persistent/searchable/output sink; optional short-lived encrypted quarantine; privacy-safe findings/markers; synthetic canary evaluation; and a retroactive containment/rotation/rebuild/backup/restore workflow. Exact current code gaps, primary research, product surfaces, test matrix, and PR slices live in [`tracedecay-v2/18-secret-detection-redaction-and-private-data-safety.md`](tracedecay-v2/18-secret-detection-redaction-and-private-data-safety.md). + +## 3. Current Architecture and Why It Blocks the Product + +### 3.1 Current physical and semantic islands + +| Domain | Current primary shape | Disconnection | +|---|---|---| +| Project registry | Global tables for projects, aliases, stores, graph scopes, artifacts | Does not provide one canonical entity namespace for sessions, agents, code, facts, or delivery. | +| Code graph | Branch-scoped graph DBs with nodes, edges, files, vectors, fingerprints, redundancy, cache | Scope is implied by physical DB; edges lack provenance, confidence, validity, and snapshot identity. | +| Sessions | `sessions`, `session_messages`, turns, FTS, offsets | Provider IDs and project keys vary; tool/reasoning structure often remains JSON. | +| LCM | Duplicate raw-message projection, summary DAG, lifecycle, FTS, payload metadata | Copies session content and uses separate identity/query paths. | +| Git correlation | Session spans and commit-session relations | Stronger provenance than other domains, but links stop at session/commit granularity. | +| Workflows | Workflow runs and agents with string references | No enforced agent/session/artifact/code identity. | +| Memory | Facts, entities, banks, vectors, trust/feedback, FTS inside graph storage | Project knowledge inherits branch-graph lifecycle and mutable-row authority. | +| Hints/analytics | Durable analytics plus hook JSONL fallback | Outcomes, inputs, policy versions, exact payloads, and downstream actions are weakly joined. | +| Automation | JSON/JSONL config, ledgers, outcomes, proposals, skill files, artifact directories | Cannot be transactionally queried with sessions, policies, facts, or provenance. | +| Payloads | LCM payloads, response handles, automation artifacts use separate conventions | Hashing, retention, ownership, access, and GC are not uniform. | +| Dashboard | Shell plus separate Memory, LCM, Graph, Savings, Diagnostics, Settings plugins | Navigation follows stores/plugins, not investigations; no true All scope. | +| Query stacks | Graph DB APIs, LCM query module, memory scorer, dashboard SQL, MCP handlers | Ranking, pagination, filtering, error semantics, and scope differ by transport. | + +### 3.2 Identity failures + +- `project_id`, `project_key`, project hash, project path, repository path, alias path, and worktree path compete as identifiers. +- Sessions may be provider-qualified or bare text depending on table/API. +- Message IDs, `store_id`, row IDs, workflow IDs, run IDs, hint IDs, response handles, and summary nodes occupy unrelated namespaces. +- Code node IDs include file path, kind, name, and line. Moving a symbol changes its identity. +- Facts and entities use local mutable integer IDs. +- Branch/worktree/PR relationships are often stored as strings or inferred from time windows. + +This makes joins heuristic and makes history brittle under moves, renames, rebases, force pushes, path aliases, transcript rewrites, and branch deletion. + +### 3.3 Missing canonical events and provenance + +TraceDecay currently normalizes enough to search and aggregate, but it does not retain one typed event vocabulary for: + +- Human prompt, assistant response, visible reasoning summary, system/developer context, and content parts. +- Tool invocation, tool result, approval, failure, retry, cancellation, and latency. +- Parent/child agent creation, message, handoff, task, goal, and lifecycle. +- File read/edit/create/delete, patch, symbol change, diagnostic, test selection, test result, and build. +- Worktree/branch/ref observation, commit produced/observed, PR/check/review/release encounter. +- Hint evaluation, hint suppression, exact injected payload, memory injection, retrieval candidates, and measured outcome. +- Automation scheduling decision, skip, lock, run, artifact, curation candidate, validation, autonomy decision, automatic effect/recovery, and downstream adoption; historical/provider approvals remain evidence only. + +Without those events, the timeline cannot distinguish observed facts from temporal coincidence or reconstruct what TraceDecay knew at a historical point. + +### 3.4 Query fragmentation + +Search currently exists as separate implementations for code FTS/vectors, session-message FTS, LCM raw/summary FTS, memory FTS/HRR, analytics, Git correlation, and automation files. Cross-project message search opens stores and merges results in application code without a stable distributed cursor or normalized rank explanation. + +The V2 query platform must replace transport-specific query orchestration. MCP, CLI, and dashboard become adapters over the same typed use cases. + +### 3.5 Dashboard gap + +The current shell has six product tabs and one selected project. URL state mainly preserves the active tab. Useful capabilities exist inside individual plugins, but the system cannot: + +- Search all entity types and projects in one query. +- Follow a prompt through parent agent, subagents, tools, code, tests, commits, PRs, hints, facts, and automation. +- Share or restore a full investigation state. +- Explain incomplete results, store selection, caps, ranking, or stale shards. +- Replay a historical message through the current hint/retrieval/ingest engine. +- Compare sessions, agents, policies, branches, snapshots, or time ranges. +- Switch a result among graph, timeline, table, matrix, chart, and inspector views. + +Large frontend owners such as the LCM page, semantic map, association graph, settings panel, and graph canvas also combine data fetching, query state, rendering, and interaction behavior. + +## 4. Alternatives Considered + +### A. One monolithic profile database + +**Advantages:** easy joins, one migration chain, one transaction boundary. + +**Rejected because:** code graph rebuilds, transcript ingest, automation, memory, and dashboard reads would share contention and corruption blast radius. Backup, retention, privacy, and project deletion would become coarse. “One brain” does not require one file. + +### B. Preserve current stores and add only an aggregate dashboard façade + +**Advantages:** quickest visible All view and smallest initial code change. + +**Rejected as target because:** it preserves duplicated IDs, N-store open/query/merge, inconsistent search semantics, missing provenance, and transport-specific business logic. It is useful only as a compatibility step. + +### C. Central PostgreSQL/pgvector service + +**Advantages:** strong concurrency, SQL federation, ANN, replication, team deployment. + +**Rejected as default because:** it adds server operations, credentials, network failure, and an online dependency to a local developer tool. The logical contracts should permit a future server backend without requiring it. + +### D. Unified logical model over federated embedded shards + +**Selected.** A profile catalog coordinates project-owned event/evidence stores, immutable graph snapshots, and content-addressed payloads. Transactions remain local; outboxes and watermarks make cross-shard consistency explicit. This preserves local-first operation and bounded failure while enabling one query/product model. + +## 5.

This avoids premature distributed-system overhead. Boundaries must allow a future daemon/query split without changing domain contracts. + +### 5.2 Bounded contexts + +1. **Capture:** source discovery, offsets, rewrite generations, hashing, parsing, redaction/classification, immutable observations. +2. **Identity Catalog:** profile, repository, project, checkout, worktree, branch/ref, provider, actor, agent instance, session, message, code snapshot, symbol lineage, aliases. +3. **Evidence Ledger:** canonical events, temporal relation assertions, provenance, confidence, sensitivity, algorithm versions. +4. **Agent Execution:** turns, messages, content parts, tool invocations/results, visible reasoning summaries, goals, parent/subagent trees, workflows, handoffs. +5. **Work Orchestration:** initiatives, immutable plan versions, canonical work items, typed dependency gates, assignments, executor routes, fenced leases/attempts, context packets, workspaces, handoffs, artifacts, acceptance, outcomes, and costs. +6. **Code Intelligence:** snapshots, files, symbol entities/occurrences, edges, diffs, diagnostics, tests, impact, ownership. The production extraction/watcher/incremental-indexing pipeline is owned by [`tracedecay-v2/25-code-intelligence-indexing-crate.md`](tracedecay-v2/25-code-intelligence-indexing-crate.md). +7. **Delivery:** Git refs, commits, worktrees, PRs, checks, reviews, releases, remotes, fetched-at state. +8. **Context Intelligence:** LCM summary DAG, compression decisions, context assembly, external payload lineage, replay. +9. **Knowledge:** versioned facts/claims, entities, decisions, contradictions, trust evidence, retrieval, feedback, curation. +10. **Policy Runtime:** hints, retrieval, routing, diagnostics, correlation, curation, scheduling, policy bundles, deterministic evaluations. +11. **Automation:** jobs, schedules, scheduler decisions, runs, agents, artifacts, curation candidates/autonomy decisions/effects/recovery, skills, outcomes, plus imported historical approval evidence. +12. **Observability and Accounting:** usage, latency, errors, caps, savings, cost, ingest/projection lag, data quality, privacy events. This context is owned by [`tracedecay-v2/26-observability-accounting-and-usage.md`](tracedecay-v2/26-observability-accounting-and-usage.md). +13. **Capability Catalog:** stable use-case definitions, transport/skill/hook/dashboard bindings, availability, safety, cost, discovery, compatibility, and generated inventories. +14. **Query and Projection:** `TraceQueryV1`, planners, read models, rankers, saved views, subscriptions, exports. +15. **Privacy Safety:** mandatory structured sanitizer, taint/sink eligibility, detector registry, protected quarantine, privacy scans/findings/remediation, and restore eligibility. This is one cross-cutting boundary owned by plans 01–04/18, not a detector reimplemented in each domain. + +### 5.3 Hook, hint, and concurrent event-stream architecture + +Hooks are latency-sensitive capture adapters, not miniature application servers. Their synchronous path is strictly bounded: + +1. Parse the host notification into typed fields and run the mandatory bounded sanitizer; incomplete/timeout returns a blocked non-content receipt. +2. Normalize the sanitized hook request, allocate the source/session sequence, and append only eligible content plus an idempotent sanitization/observation receipt to a private spool or activity-shard journal. +3. Read one immutable policy/context snapshot selected by explicit watermarks. +4. Classify intent, generate candidates, apply relevance/dedupe/cooldown/token/privacy budgets, and render at most the allowed hint payload. +5. Append the evaluation/envelope receipt and acknowledge the host; slower enrichment/projectors run asynchronously. + +The hot path performs no cross-project fan-out, embedding, repository indexing, network fetch, automation run, or long write transaction. Its p95 added wall time target is 10 ms for notification-only hooks and 25 ms for prompt-evaluation hooks on the reference corpus; timeout returns no hint plus a durable, non-content error receipt. + +Ordering and concurrency contracts: + +- Each provider artifact/source instance has a monotonic source sequence; each session/agent stream has a projected sequence. There is no invented total global order. +- Every observation carries occurred time, ingested time, source sequence, rewrite generation, and causation/correlation links. Late events are inserted without rewriting prior history. +- One bounded writer actor owns each SQLite shard connection. Concurrent agents enqueue append batches through a private spool; read services use short-lived read-only snapshot pools. +- WAL, busy timeout, queue depth, maximum batch bytes, maximum transaction duration, and checkpoint thresholds are explicit configuration with safe defaults and telemetry. +- Queue saturation applies tiered backpressure: coalesce rebuildable notifications, spill canonical observations durably, and reject/mark optional enrichment. It never silently drops prompts, tool events, approvals, edits, or outcomes. +- Idempotency is per source record. Projectors and outbox consumers are at-least-once and idempotent. Leases are fenced by generation; a crashed owner cannot resume writes after a new owner takes over. +- Readers receive vector watermarks and may request frozen, live, or eventual consistency. No read transaction survives UI think time or cursor pagination. +- Crash tests cover process death before/after spool fsync, observation commit, outbox commit, hint render, host acknowledgement, projector checkpoint, and WAL checkpoint. + +The hint engine is a deterministic, versioned policy pipeline: + +`RequestFacts -> context snapshot -> intent categories -> capability candidates -> eligibility/privacy -> relevance -> repetition/cooldown -> token/latency budget -> rendered payload -> terminal outcome` + +Every evaluation records policy bundle, classifier, tool catalog, project/index, memory/fact, skill, configuration, and prompt-template digests; candidate scores; suppressions and reasons; exact injected payload reference; latency; and terminal outcome. Outcomes distinguish acted, ignored, contradicted, duplicate, unavailable capability, unresolved, missed capability, human correction, and unknown observation horizon. Historical replay can use exact historical artifacts, current artifacts, or an explicit mixed comparison; missing artifacts make replay incomplete rather than approximate silently. + +Parent/subagent spawn, delegation, message, handoff, join, interruption, goal, and completion are canonical events. Multiple agents may append concurrently, but shared branch/worktree/file impact is derived from evidence-bearing relations, not assumed from temporal overlap. + +#### Incremental Context Scout + +An optional daemon-side `IncrementalContextScout` consumes the canonical event outbox after capture/projectors and incrementally prepares context while a Turn evolves. It may use deterministic rules and, when the configured model gateway advertises an eligible capability, a low-latency model such as App Server Spark. The model proposes structured bounded exploration only; application authorization executes at most catalog-approved read-only message/LCM/memory/code/Git/delivery/coordination/task capabilities, and pure policy decides whether one anchored suggestion beats silence. Model/provider names, fallbacks, tools, scope, egress, budgets, and delivery modes come from the configuration/catalog handshake, never hardcoded daemon logic. + +The scout emits a `SuggestionEnvelopeV1` addressed to an exact profile/thread/Turn/session/agent/logical-message tuple, with expiry, policy/config/catalog/model/index/watermark receipts, evidence and retrieval anchors, dedupe fingerprint, and host delivery policy. The hook hot path never waits for scout model/search/tool work; it performs only a bounded pending-envelope claim/revalidation/render within a 2 ms p95 target and returns no suggestion on contention, lateness, ambiguity, privacy failure, or weak relevance. Late/stale/superseded envelopes are not injected into another Turn. No suggestion is the default; one category gets at most an initial delivery and one evidence-strengthened escalation within hard per-Turn/session/token budgets. + +Task/ticket/claim events are not global board broadcasts. A sibling change reaches a working agent only when a typed dependency, material work-claim overlap, blocker, handoff/context packet, or invalidated assumption connects it to the current task and exact Turn. Observatory, Causal Loom, Hint Lab, Settings, CLI/MCP/API/SDK, replay, evaluation, privacy, and phased cutover are specified in [`tracedecay-v2/22-incremental-context-scout-and-suggestion-envelopes.md`](tracedecay-v2/22-incremental-context-scout-and-suggestion-envelopes.md). + +### 5.4 Generated capability and tool catalog + +TraceDecay currently has substantial capability, but definitions are scattered across MCP schemas, CLI commands, skills, dashboard actions, provider hooks, and prose. V2 generates one versioned catalog from typed application use cases. Each capability declares: + +- Stable capability/use-case ID, version, owner crate/domain, aliases, status, and replacement/deprecation. +- Inputs/outputs, scope kinds, entity/event kinds, read/mutate classification, side effects, idempotency, streaming/pagination, cost/latency class, and required freshness. +- Availability prerequisites: daemon, indexed project/ref, live remote refresh, credentials, provider/host support, protected-mode unlock, and permissions. +- Privacy/sensitivity behavior, audit events, and exactly one execution mode: read-only, direct commit, confirmed destructive, autonomous policy effect, resumable workflow, or internal host lifecycle. Curation never generates an item approval/apply binding. +- MCP tool, CLI command, HTTP route, dashboard command/panel, skill, and hook-intent mappings generated from the same definition. +- Examples and compact routing copy suitable for dynamic hints; catalog digests are part of policy replay. + +The compatibility inventory must include every current capability family: project/registry/doctor/diagnostics; code search/context/grep/definition/call/path/impact/tests/health; branch list/search/diff, PR/commit/changelog, correlated sessions/workflows, Git refresh/fallback; sessions/LCM search/load/status/lifecycle/export; memory/facts/entities/feedback/curation; hints/analytics/usage/cost; automation/scheduler/runs/artifacts/proposals/skills; configuration/integrations/daemon/watch/index/migrate/repair/backup; query/render/response handles. The generated inventory, not a hand-maintained list, is the cutover authority. + +Discovery is itself observable. For each eligible prompt, the policy runtime records capabilities considered, suggested, used, unavailable, or missed; whether a fallback was chosen; and user correction evidence. The dashboard exposes coverage/drift by intent category without turning every prompt into a noisy catalog advertisement. + +The complete current surface and output audit lives in [`tracedecay-v2/21-cli-mcp-tool-surface-and-output-unification.md`](tracedecay-v2/21-cli-mcp-tool-surface-and-output-unification.md). Its generated inventory must cover all 104 source MCP tool definitions (103 installed at 0.0.47; 102 at the older frozen inventory — plan 21's generated audit at commit `9f7a1108` arbitrates these counts), the complete recursive top-level/nested/hidden CLI command tree, runtime capability filtering, every current dashboard route, every alias/allowlist/default/format/effect/error, and the installed-versus-source catalog digest; CLI and dashboard-route counts are frozen by that generated inventory, never hand-maintained numbers. One sealed typed application view feeds canonical JSON and a pure presentation model; MCP defaults to compact Markdown, CLI defaults to deterministic human output, machine formats are explicit, and no renderer traverses arbitrary JSON or silently drops fields. + +### 5.5 Agent proximity, work claims, and non-redundant coordination + +TraceDecay should make agents lightly aware of nearby work without turning the hint engine into a chatty presence bot or a global lock manager. The canonical coordination objects are: + +```text +AgentPresence(agent, session, parent, provider, host, profile, heartbeat, expires) +WorkClaimV1(agent, goal/task, repo, worktree, ref/PR, files/symbols/query/domain, + read-or-write intent, planned artifact, safe summary, redundancy mode, + status, version, started, heartbeat, expires, retrieval anchors) +``` + +`redundancy_mode` distinguishes accidental overlap from deliberate best-of-N, diverse review roles, paired/shared implementation, sequential handoff, and explicitly disjoint work. An advisory claim never grants write ownership. Existing store/file/Git/lifecycle leases remain the authority for mutations that require exclusion. + +Agent-nearness is an evidence-scored query, not “same repo means warn”: + +- Direct same task/goal/artifact or overlapping file/symbol write intent. +- Same worktree or branch with intersecting write/diagnostic/test/PR scope. +- Parallel worktrees with the same branch, PR, merge base, affected symbols/tests, or semantically overlapping research query. +- Parent/subagent/sibling/handoff relationships and declared disjoint scopes. +- Claim/presence freshness, current status, heartbeat/TTL, provider coverage, and uncertainty. + +The dynamic hint is eligible only at a high-value boundary: session/subagent start, before a first edit/mutation, before expensive research/index/PR review, when a new high-overlap claim appears, or when either claim changes materially. It is suppressed for stale claims, low overlap, acknowledged overlap, declared intentional redundancy, already coordinated peers, and repeated unchanged overlap. + +Compact example: + +> Nearby work: 2 agents overlap `session-query / subagent dedupe`. Maxwell is reviewing hooks/catalog in this repo; Tesla is mapping Turn projection. Inspect `session:019f…` or run `nearby_agents`; coordinate only if your planned files overlap. + +Payload rules: + +- One deterministic safe summary line per relevant agent, normally at most 160 characters and at most two peers plus a hidden-count/inspect action. +- Stable agent/session/goal/work-claim/research anchor IDs; no full prompt, chain-of-thought, secret path, or private payload. +- Exact reason/overlap fields and source watermark available through inspector/tool, not dumped into the prompt. +- Dedupe key `(recipient_agent, overlap_signature, claim_versions, policy_bundle)`; one delivery until material change, acknowledgement, expiry, or configured cooldown. +- Actions: inspect context, message peer, request handoff, accept deliberate overlap, mark scopes disjoint, update/release claim, or mute this signature. Silence remains a successful outcome when no action is useful. + +Analytics measures the opportunity funnel, not raw hint volume: + +- Eligible overlap, suppressed reason, emitted/delivered, inspected, messaged, handed off, scopes split, deliberate redundancy confirmed, ignored, false positive, unresolved, expired. +- Subsequent duplicated reads/queries/edits/tests and conflicting writes by evidence class; “work avoided” is estimated/labeled, never asserted from temporal coincidence. +- Precision among judged high-overlap hints, useful-action rate, repeat rate, token/latency cost, first-useful-context time, and missed-overlap corrections. +- Breakdowns by same versus parallel worktree, provider, parent/sibling/unrelated agents, task type, read/write intent, and policy version. + +Historical replay corpus: + +- Current redesign parent session `019f4906-a411-7a11-ad3f-0d58deb0e847` and its anchored child sessions: mostly disjoint authored plans plus intentionally overlapping review passes; copied coordination events and missing parent tool-use IDs test false-positive resistance. +- PR #359 review wave child sessions `agent-ac3ce9b1ebf998cfb`, `agent-a245d2442cefc621d`, `agent-a96d21dc6391ceba8`, and `agent-a6661fd133491631c`: identical review prompts test deliberate ensemble labeling versus accidental duplication. +- Cursor shared-worktree session `ebc96a27-b046-4c88-865f-b38d76da9d2d`: many agents in one checkout test explicit file ownership, collision risk, and compact neighborhood summaries. +- Cursor coordination session `c48804a4-9c7f-4ce1-a771-95c3702654b2`: nine sibling agents with disjoint file ownership test that declared scopes suppress redundant warnings while preserving material conflict alerts. + +The replay lab compares no-awareness, current policy, and candidate policy; shows every candidate/suppression/payload; and never writes a live claim, message, fact, counter, or hint outcome. + +### 5.6 Unified multi-repository, project, and worktree scope plane + +`ScopeSelectorV2` is a domain contract shared by every transport. It selects All, profile, saved project set, repository, project, checkout, worktree, branch/ref, commit/snapshot, PR, session, agent, workflow, initiative, plan, work item, execution attempt, executor, saved view, or collection; includes explicit freshness/partial/as-of policy; and resolves natural-language names, paths, remotes, and stable IDs through one application service. + +Resolver invariants: + +- Stable ID, exact path/remote/alias, token-aware terms, fuzzy candidates, and graph-related candidates are distinct explained channels. +- An explicit target either resolves or returns bounded candidates and one ready-to-retry request; it never runs against `current` instead. +- `current` is permitted only when the request supplies no target and is always rendered as the resolved project/worktree/ref/head. +- `project_key`, first/last CWD, path hashes, store directories, and graph filenames are internal aliases/evidence, not public identity. +- Repository/project/worktree/ref identity survives moves, renames, rebases, branch deletion, and checkout removal through temporal aliases and adoption receipts. +- Domain availability is independent: missing/stale code graph does not hide profile sessions, messages, facts, Git, automation, or registry tools. + +Profile `activity.db` stores canonical provider sessions, Turns, messages, agents, and tool events once. Project/worktree attribution is a bitemporal relation per observation with evidence roles such as `produced_in`, `executed_in`, `queried`, `discussed`, and `observed`; a session may have zero, one, or many attributed repositories over time. Search and exact-load tools route global entity/retrieval IDs through the catalog rather than requiring the caller to select a store or change CWD. + +Code federation selects one immutable graph generation per repository/worktree/ref snapshot, reports dirty/base/index drift, prunes shards with catalog statistics, and merges bounded results with per-repository diversity and source explanations. Cross-repository edges—dependency, plugin/host API, PR/base/head, fork/patch, generated artifact, benchmark/downstream, and session/agent evidence—are typed, versioned, and traversed only when requested or policy-authorized. All-scope never means “open every database and concatenate.” + +The Rspack/Rsbuild/React Router family is the primary conformance system: one query must resolve the plugin, upstream Rsbuild API, Rspack implementation, React Router semantics, related worktrees/PRs, and downstream benchmark evidence without manual registry loops. CLI common flags, MCP `scope`, HTTP schemas, generated SDK types, dashboard scope chips, distributed cursors, errors, and coverage metadata are generated or validated from the same contract. See [`tracedecay-v2/16-cross-project-repository-worktree-scope.md`](tracedecay-v2/16-cross-project-repository-worktree-scope.md). + +### 5.7 System convergence, organization, and extensibility + +The rewrite is complete only if it removes fragmentation rather than recreating it in new crates. The canonical flow is: + +```text +source/provider -> classify/sanitize/capture -> observation journal -> identity/evidence +-> deterministic projectors -> query/search/graph -> policy/replay -> application use case +-> generated/thin CLI | MCP | API/SDK | hook | dashboard/lab adapter +``` + +Each arrow crosses one typed contract. No downstream layer reparses a provider payload, resolves a project independently, reruns a different secret detector, opens arbitrary storage, constructs its own ranking, infers remediation, or invents a transport-specific status/error. Cross-cutting metadata—scope, sensitivity/redaction, provenance, confidence, occurred/ingested/valid time, watermarks, coverage, capability/version, cost, authorization, retention—survives end to end. + +Convergence rules: + +- One canonical domain type/registry owns each identity, event, scope, predicate, capability, error, receipt, query, policy, and command semantic. +- One repository/application port owns each read/write use case. Store SQL, provider parsing, and transport rendering never leak across the boundary. +- One generator/contract IR emits CLI flags, MCP/HTTP schemas, OpenAPI/JSON Schema, SDK types, dashboard client types, tool/skill/hint metadata, docs, and compatibility inventory. +- Versioned SPIs admit providers, detectors, projectors, rankers, policies, tools, and renderers under explicit capability/safety/resource contracts. An extension cannot create an unregistered side store or bypass sanitization/scope/auth/audit. +- Physical sharding, graph generations, caches, workers, and future daemon/query separation scale behind stable ports without multiplying semantic models. +- Every temporary V1 adapter has a named owner, inbound/outbound contract, parity fixture, metrics, last-allowed phase, deletion PR, and CI rule preventing new call sites. +- Architecture lint enforces dependency direction, transport/store isolation, raw-string/SQL restrictions, schema/catalog bijections, public-type uniqueness, module/file complexity budgets, and zero orphan compatibility paths. +- A convergence scorecard tracks duplicate authorities, bypass call sites, direct SQL/store opens, schema drift, adapter call volume, parity gaps, extension conformance, large files/condition growth, and retired code/data. + +The target is modular, not microservice-shaped: one Rust process initially, bounded crates and internal services, predictable names/layout, small reviewable modules, and few high-quality extension seams. New behavior should extend a registry/trait/predicate and inherit identity/scope/privacy/query/replay/observability behavior automatically. The complete current-to-target convergence matrix and retirement program live in [`tracedecay-v2/19-system-defragmentation-convergence-and-extensibility.md`](tracedecay-v2/19-system-defragmentation-convergence-and-extensibility.md). + +### 5.8 Fully autonomous curation + +Memory, fact, managed-skill, session-reflection, profile-learning, and related Hermes-style curation are continuous autonomous system behavior—not proposal inboxes awaiting human preview/approve/apply/rollback clicks. The canonical loop is: + +```text +evidence -> candidate -> deterministic validation/policy -> transactional revalidation +-> autonomous staged effect -> use/outcome monitoring -> autonomous revise/recover/archive +``` + +- No public curation-item command named preview, approve, reject, apply, install, or rollback exists. +- The policy runtime remains pure; an application-owned worker autonomously applies every eligible owned effect with exact expected versions, privacy/ownership/evidence/resource gates, idempotency, and audit receipts. +- Unsafe, weak, foreign-owned, secret-like, conflicting, or out-of-authority candidates are automatically rejected, deferred for evidence, protected, or quarantined; they do not become a needs-human queue. +- Operators control curation through versioned configuration, pause/resume/run-now, pin/protect/exclude, and feedback. The UI exposes history, reasons, staged scope, use/outcomes, and automatic recovery without making inspection a gate. +- Automatic recovery/revision is policy-driven and outcome-triggered. Historical V1/provider approval/rejection/apply events remain imported evidence but do not define the V2 workflow. +- Destructive non-curation administration—store deletion, migration, key destruction, external publication—retains its separate safety/confirmation contract. + +The configuration system, including autonomy policy and the redactor/detector policy, is fully discoverable/editable in Settings and through generated navigable CLI commands; [`tracedecay-v2/20-configuration-control-plane.md`](tracedecay-v2/20-configuration-control-plane.md) owns the exact control-plane contract. + +### 5.9 Canonical task/plan graph and multi-agent executor + +TraceDecay owns one profile-level initiative/plan/work-item graph in the activity shard. A board is a saved authorized `TraceQueryV1` projection plus layout/grouping/policy; it is never a database, ownership boundary, dispatch selector, or source of task identity. The same work item may appear simultaneously in a project board, an agent slice, a repository view, a Kanban lane, a dependency DAG, a timeline, and an All initiative without copying its ID, dependencies, history, or authority. + +This is a native TraceDecay Kanban/orchestration implementation sourced from a deliberate Hermes port-and-improve program—not an adapter that forwards task operations to Hermes. Proven Hermes algorithms, tests, schemas, and interaction patterns may be ported directly under pinned MIT provenance; incompatible pieces are behaviorally ported or replaced with stronger V2 designs. TraceDecay ships and operates the resulting scheduler, task graph, worker lifecycle, tools, and UI. Hermes remains optional only as an execution host or historical capture source. + +The core entities remain separate: `Initiative`, `Plan`, immutable `PlanVersion`, versioned `WorkItem`, typed gating dependency, acceptance criterion, decision, assignment, `ExecutionAttempt`, fenced `TaskLease`, executor registration/route receipt, workspace binding, `ContextPacketManifest`, handoff, artifact, outcome, and cost. Task↔Thread/Session/Turn/Agent and task↔code/Git/PR relations are many-to-many, bitemporal, evidence-bearing links. A long thread may serve many tickets; one ticket may span many agents, sessions, repositories, worktrees, branches, and PRs. + +Execution rules: + +- Gating edges form a validated DAG; informational/evidence relations may cycle but never unlock work. Readiness, critical path, slack, and dispatch derive from current plan versions, gates, schedules, budgets, acceptance, capabilities, and leases—not draggable status strings. +- Assignment names desired ownership. `WorkClaimV1` remains advisory proximity evidence. Only a compare-and-swap `TaskLease` with a monotonic fence epoch grants execution authority. +- Each attempt pins requested and actual host/provider/model/revision/reasoning effort, skills, tool-catalog generation, effect grants, privacy/egress class, workspace, token/cost/runtime budgets, retry policy, context packet, and deadlines. Codex, Claude, Cursor, Hermes, and custom executors implement one adapter SPI; none owns task truth. +- Lease acquisition revalidates task/plan revisions, dependency readiness, executor capacity, budget, exact repository/worktree/ref/snapshot, active authoritative reservations, and artifact/file/symbol/test overlap. Heartbeat is constant-cost. Completion/cancellation atomically revokes the lease and broker credentials. Late canonical writes and brokered effects from an old epoch are rejected even if its process remains alive; a non-preemptible external effect already in flight is quarantined as unknown, its replacement is blocked, and reconciliation must prove stop/receipt/compensation before requeue. +- A multi-repository attempt has one primary writable workspace unless an explicit coordinated multi-write capability is granted. User-owned dirty worktrees are preserved and block unsafe starts; branch, push, PR, merge, release, and external-message effects remain separately authorized workflows. +- Versioned context packets contain objective, constraints, acceptance, dependencies, parent handoffs, material sibling decisions/results, relevant prior failures, exact Thread/Turn and code/Git/PR anchors, scope/workspace versions, watermarks, query/config/catalog/policy/privacy digests, token budget, expiry, and explicit omissions. Workers never receive a global-board dump or arbitrary sibling prompts. +- Task materiality projectors emit a candidate only when a dependency, handoff, shared decision, direct workspace/artifact overlap, base/PR/check change, or authoritative sibling result can change the recipient's next action. Plan 22 addresses at most one compact, deduped suggestion to the exact active agent/Thread/Turn; boards never broadcast. +- Decomposition, routing, readiness, fairness, retry, circuit-breaking, packet selection, and materiality are pure replayable policies. Application services validate and apply their effects within configured authority. Models may propose schema-valid plans/routes/summaries but cannot widen scope, grants, budget, egress, tools, or destructive effects. + +The Rspack/Rsbuild/React Router conformance initiative must decompose one graph into independently leasable repository tasks, fan them across explicitly selected Codex and Claude (plus optional Cursor/Hermes/custom) routes, preserve cross-repository gates, join them through verifier/synthesizer/integration tasks, and render focused per-agent/per-repository boards or one global DAG without copies. It must prevent the observed wrong-ambient-board repair pattern, lost dependencies, dispatch of already-complete work, and stale workers after manual completion. Full schemas, executor protocol, UI lenses, Orchestration Lab, Hermes evidence, migration, evals, and PR slices live in [`tracedecay-v2/24-canonical-task-plan-graph-and-multi-agent-executor.md`](tracedecay-v2/24-canonical-task-plan-graph-and-multi-agent-executor.md). + +## 6. Canonical Identity and Evidence Contracts + +### 6.1 `EntityRef` + +Use a canonical UUIDv7 plus an entity-kind discriminator. SQLite row IDs never cross an API boundary. UUID allocation is durable data, not a projection: the immutable identity ledger is backed up and restored with the catalog/activity manifests. Exact source identities use deterministic namespaced IDs; ambiguous/resolved entities receive persisted UUIDv7 allocations that survive reimport and rebuild. + +Required entity kinds: + +- Profile, project, repository, remote, checkout, worktree, branch/ref, commit, tree, pull request, check, review, release. +- Provider, host instance, model, actor, agent instance, session/thread, workflow, run, turn, message, content part. +- Tool definition, tool invocation, tool result, approval, goal, task, handoff. +- Code snapshot, file identity, file occurrence, symbol identity, symbol occurrence, diagnostic, test, build. +- Fact, fact version, knowledge entity, decision, contradiction, retrieval, feedback. +- Policy bundle, policy evaluation, hint, automation job/run/artifact/skill, curation candidate, autonomy decision/effect/recovery. +- Query, saved view, annotation, export, payload blob. + +### 6.2 `ObservationEnvelopeV1` + +Every source adapter emits the same outer contract: + +- Deterministic `observation_id` derived from source instance + artifact identity + rewrite generation + canonical source position. The privacy-domain/key-epoch-bound source fingerprint verifies collision/rewrite continuity but is not an ID input, so key rotation cannot mint duplicate observations; no unkeyed secret-content hash crosses the sanitizer. +- Source system, provider, host instance, artifact identity, rewrite generation, byte/row offset, sanitized output digest, keyed source fingerprint, and sanitization receipt. +- Schema version and parser version. +- Occurred time and ingested time; missing-time reason when unknown. +- Project/repository/worktree/session hints before canonical resolution. +- Sensitivity class, redaction/quarantine state, detector/policy/parser digests, and scan completeness. +- Typed sanitized payload discriminator and safe payload reference; protected secret refs use the isolated quarantine domain and never serialize to normal events/APIs. +- Idempotency key: source instance + artifact identity + rewrite generation + canonical source position; the separately stored keyed fingerprint must match under the current epoch or an explicit rotation-continuity proof. + +Ingesting the same source twice must produce zero additional observations. + +### 6.3 Canonical events + +Observations project into immutable events. Corrections create superseding events; they do not rewrite history. + +Each event carries: + +- Canonical `event_id`. +- `kind`, schema version, occurred/ingested timestamps. +- Owning activity/project shard plus actor, session, run, and snapshot references when resolved; project attribution is zero-to-many evidence relations, never one implicit primary project. +- `correlation_id` for grouping and `causation_id` only when direct causation is supported. +- Source observation IDs and provenance ID. +- Payload reference; full attributes live in one content-addressed blob (`attrs_blob_id`), and registry-promoted attributes are additionally indexed through the store's `event_attr_index` tables (plan 02). +- Sensitivity and retention class. + +### 6.4 `RelationAssertion` + +All cross-domain edges use one evidence-bearing contract: + +- Subject, predicate, object. +- Valid-from/valid-to and observed-from/observed-to. +- Evidence class: observed, provider-declared, user-declared, derived-exact, inferred, heuristic. +- Confidence and confidence rationale. +- Supporting observation/event IDs. +- Producing algorithm, model, parser, or resolver version. +- Scope and sensitivity. +- Supersession/tombstone state. + +The UI must never label an inferred or heuristic relation “caused,” “created,” or “changed.” It uses “correlated,” “likely related,” or the exact evidence label. + +### 6.5 Schema and predicate registry + +Typed events and relations may preserve unknown provider JSON for forensic replay, but unknown fields never become query-semantic automatically. A versioned registry defines: + +- Event/entity/relation kind and owning bounded context. +- Allowed subject/object kinds and inverse predicate. +- Cardinality and uniqueness rules. +- Required evidence class, provenance, confidence, and temporal fields. +- Promoted indexed attributes and their data types. +- Sensitivity and retention defaults. +- Compatible schema versions and migration/projector version. + +Writes that violate the registry are quarantined with their original observation. Query builders and generated clients derive their legal predicates from the same registry. + +### 6.6 Stable code identity + +Separate logical symbols from snapshot occurrences: + +- `SymbolEntity`: stable concept within a repository; no line number in its identity. +- `SymbolOccurrence`: file, range, signature, qualified name, visibility, and extractor version inside one code snapshot. +- `SymbolLineage`: evidence-bearing rename/move/split/merge/same-lineage assertions across snapshots. +- `CodeEdge`: snapshot-scoped source/target occurrences, kind, location, resolver version, confidence, provenance. + +Ambiguous lineages remain separate candidate links. TraceDecay must prefer a visible uncertain relationship over a silent incorrect merge. + +## 7. Physical Storage Design + +### 7.1 `catalog.db` per profile + +Owns the minimum metadata required to plan queries without opening every shard: + +- Profiles, repositories, projects, aliases, checkouts, worktrees, remotes. +- Durable canonical-ID allocation ledger for profile/global identity classes and opaque entity locators; entity versions and source aliases remain in their owning shard. +- Shard registry, capabilities, schema versions, coarse sizes/time ranges/entity counts, health, and last watermark. +- Opaque cross-shard relation/event locators and nonsensitive aggregate rollups. +- Opaque saved-view/export IDs and manifests. +- Projection/outbox watermarks and migration receipts. + +The catalog does not store message/query literals, annotations, payloads, sensitive alias values, or raw project content. Saved-view state and annotations live as encrypted saved-view/annotation content rows in the activity shard (plan 02), not a separate store; the catalog retains opaque IDs and safe locators. + +### 7.2 `activity.db` per profile + +Owns canonical provider activity that may relate to zero, one, or many projects: + +- Transcript observations and canonical messages/content parts. +- Actors, agent instances, sessions, turns, tools/results, goals, workflows, and handoffs. +- Provider/host/model aliases and source offsets. +- Session-to-project/repository/worktree/branch/snapshot relation assertions with evidence. +- Cross-project policy evaluations, usage/accounting events, and activity search projection. +- Profile-scoped facts/memory, managed skills, policies, automation jobs/runs/artifacts, curation candidates, autonomy decisions/effects/outcomes/recovery, saved-view content, and annotations that do not belong to one repository privacy domain. Imported V1/provider proposal/approval/apply rows remain labeled historical evidence only. +- Outbox, projection watermarks, and retention horizon. + +Project attribution is a relation, not a required `project_id` column on canonical transcripts. Generic chats remain first-class instead of being forced into a project store. + +### 7.3 `project.db` per canonical repository/privacy domain + +Owns canonical project evidence: + +- Project/source observations, project entities/versions/aliases, relations, and activity locators. +- Scoped session/agent/workflow projections referencing canonical activity IDs, not copied message bodies. +- Git/delivery observations and relations. +- Project knowledge, facts, trust events, retrieval/feedback. +- Hints/policy evaluations and outcomes. +- Automation jobs, runs, artifacts, curation candidates/autonomy decisions/effects/recovery, skills, and imported historical approval evidence. +- Project-level search documents, representations, facets, and rollups. +- Transactional outbox and projector checkpoints. + +Project memory moves here and no longer inherits branch graph lifecycle. + +Ownership follows declared scope: profile/zero-project/cross-project knowledge, policy, skill, and automation data lives in `activity.db`; repository/project-scoped equivalents live in that privacy-domain `project.db`. Cross-scope reuse creates evidence relations and locators, never a silent copy or a fabricated primary project. + +Projects, checkouts, worktrees, and monorepo subprojects are scoped views over a canonical repository shard; they are not alternative shard identities. Non-repository profiles and stricter retention/encryption boundaries use an explicit privacy-domain shard. + +### 7.4 Immutable graph snapshot generations + +Do not create one tiny SQLite file for every commit. Use packed immutable generations with deduplicated file/symbol content, a manifest mapping snapshot IDs to generation/overlay, bounded dirty overlays, background compaction, retention, and atomic generation swaps. Physically, a generation is a packed immutable SQLite Generation DB as defined by plan 02; plan 25 owns the indexing pipeline that builds generations. Benchmark the pack size/file-count threshold before fixing it in the storage ADR; the benchmark lands with PR 6C's staged/sealed pack implementation. + +Graph generations own: + +- File and symbol occurrences. +- Call/type/use/annotation edges. +- Diagnostics, tests, coverage/test-map data. +- Fingerprints, redundancy, complexity, dependency matrices. +- Rebuildable FTS/vector representations tied to extractor/version. + +Branches and worktrees point to immutable snapshots or a snapshot plus bounded dirty overlay. The physical generation never substitutes for explicit snapshot identity in rows or APIs. The manifest sets maximum open generations, overlay depth, file count, and compaction triggers. + +### 7.5 Privacy-domain content-addressed payload stores + +Replace separate LCM payload, response-handle, and automation-artifact conventions with one service: + +- `privacy//blobs////`; plan 02 §8 is the normative layout. +- Staged private write, hash/size verification, atomic rename, then reference publication. +- Keyed content IDs prevent equality leakage across encryption/retention domains; deduplication occurs only inside one domain. +- Blob metadata: MIME/schema, compression, sensitivity, encryption key ID, created time, retention class. +- `blob_refs`: owner, purpose, range, source, privacy/key domain, advisory refcount/protection state. +- Integrity scan, orphan grace, missing-ref quarantine, and idempotent GC. +- GC mark-and-sweeps from signed shard manifests and committed outboxes rather than trusting refcounts alone. +- Protected mode encrypts sanitized eligible payloads with a profile/project key; unsanitized/plaintext forensic bytes are never normal blob inputs. +- Secret-like forensic payloads do not use this normal content-addressed service. They use plan 02/18's `privacy//protected/` object family plus `quarantine.db` append-only `Staged -> Attached | Retiring -> Retired` journal: random IDs, per-record encrypted keys, no deduplication, no normal backup/export/index access, and 24-hour default retention only for unreferenced staging. + +### 7.6 Deferred analytical segments + +Parquet/DuckDB is not part of the first V2 default. A later ADR may add rebuildable analytical segments only if measured SQLite aggregate projections miss a named performance gate. The vector/ANN index structure for `representations` is likewise a deferred ADR: PR 14A benchmarks candidates, and no ANN structure is fixed before its gate evidence. + +### 7.7 Write ownership and consistency + +- Each SQLite shard has one bounded writer actor. It owns the write connection, serializes short transactions, and exposes typed commands rather than a shared connection mutex. +- Hook/capture clients append through a private per-profile spool with `0600` files, length/checksum framing, fsync policy, maximum disk budget, and recovery scan. Canonical records are acknowledged only at their declared durability level. +- Read services use bounded read-only connection pools and SQLite snapshot transactions. They never wait behind background compaction/migration without returning an explicit busy/partial state. +- Capture owns observation appends. +- Identity service owns canonical IDs and aliases. +- Code indexer owns graph snapshots; plan 25 owns its extraction/watcher/incremental-indexing crate. +- Knowledge service owns fact/trust/version mutations. +- Automation service owns jobs/runs, curation candidates, autonomy decisions, transactional effects, outcomes, monitoring, and recovery. Provider tool approvals project into activity/tool evidence; legacy proposal/approval/apply rows are immutable imported evidence only and have no V2 action queue. +- Blob service owns files and refs. +- Each owner commits domain rows and an outbox record in one local transaction. +- Each shard exposes a monotonic outbox sequence. Consumers are at-least-once and idempotent by `(shard_id, sequence, projector_version)`. +- Catalog and projections consume outboxes idempotently and expose a vector watermark across involved shards. +- Dual capture never advances a V2 source offset unless the observation/outbox commit succeeds. V1 remains authoritative until the domain cutover freeze watermark. +- A cutover requires zero unexplained parity gaps and projection lag below two seconds for 24 hours; rollback restores V1 source-offset ownership from the migration receipt. +- Cross-shard queries report vector watermarks; there is no hidden distributed transaction. +- Backfills use leases, checkpoints, bounded batches, pause/resume, and idempotency keys. +- Writer commands expose queue time, transaction time, rows/bytes, retry class, and durable sequence. Overload thresholds are tested with many simultaneous parent/subagent streams. +- WAL checkpointing is coordinated with readers and backup manifests. Disk-full, permission, corruption, busy, process-death, and torn-spool paths have distinct typed errors and repair receipts. + +## 8. Logical Schema + +The exact migrations are produced in Phase 1, but the model is fixed by this plan. + +### 8.1 Core logical families + +Plan [`tracedecay-v2/02-store-crate.md`](tracedecay-v2/02-store-crate.md) §11 is the sole normative physical table/column/key/index/retention authority. This master fixes logical families and invariants only: + +- canonical allocation, aliases, observations/provenance/sanitization receipts, entities/versions, events, relation assertions/evidence, source heads/gaps, outbox, projection leases/checkpoints/dead letters, commands, retrieval-anchor routes/records, and project-set versions; +- privacy-domain blob refs, protected-quarantine attachment saga/journal, holds, retention, backup/restore, migration/consolidation/registry/retirement receipts; +- registered configuration revisions/preparations/releases/activation members, research manifests/tagged subjects/anchors, retrieval-evaluation artifacts, scout suggestions, tasks/execution authority, and observability/accounting families. + +Every logical ID/schema/reference above lowers losslessly through plan 02. A consumer plan may state required fields but cannot restate a competing SQL tuple, alias, or path. + +### 8.2 Profile activity and agent/session projections + +- Canonical activity includes threads/session variants, thread-session assertions, actors/agents, workflow runs, Turns, messages/content parts, provider-exposed reasoning, tools/results/approvals, goals, handoffs, coordination presence/claims, project/worktree/ref attribution, research/evaluation history, and the complete plan/task/executor journal. +- Accepted #428 semantics are mandatory: provider/native session ID is non-unique alias/collision evidence. A stable canonical session variant/source identity distinguishes divergent histories; message identity/order is keyed by canonical `session_id` plus native ordinal/source evidence, never `(provider, native_session_id[, ordinal])` alone. +- Provider tool approvals are activity evidence. V2 autonomous memory/skill/fact evolution uses candidates, policy/autonomy decisions, effects, outcomes, and recoveries—not a live approval queue. +- Canonical rows live in `activity.db`; project shards reference their IDs and evidence relations without copying transcript bodies. Large/private content remains in receipt-bound encrypted blobs. + +### 8.3 Code and delivery projections + +- `repositories`, `checkouts`, `worktrees`, `refs`, `commits`, `pull_requests`, `checks`, `reviews`, `releases`. +- `project_sets`, `repository_relations`, `checkout_aliases`, `worktree_aliases`, `snapshot_generations`, and `cross_repository_edges` support federated scope without store-path identity. +- `code_snapshots`, `files`, `file_occurrences`, `symbol_entities`, `symbol_occurrences`, `symbol_lineage`, `code_edges`. +- `file_changes`, `symbol_changes`, `diagnostics`, `tests`, `test_results`, `impact_assertions`. + +### 8.4 Knowledge, policy, and automation projections + +- `facts`, immutable `fact_versions`, `fact_relations`, `trust_events`, `retrieval_events`, `feedback_events`. +- `policy_bundles`, `policy_evaluations`, `hint_evaluations`, `retrieval_evaluations`, `correlation_evaluations`. +- `automation_jobs`, `scheduler_decisions`, `automation_runs`, `run_events`, `automation_artifacts`, `skill_versions`, `curation_candidates`, `autonomy_decisions`, `autonomous_effects`, `outcome_monitors`, `automatic_recoveries`, and imported `legacy_approval_events`. + +### 8.5 Search and representation projections + +- `search_documents(owner_id, field, search_eligible_text, tokenizer_version, sanitization_receipt_id, sensitivity, source_watermark)`; repository conversion rejects unclassified/secret/unknown text. +- `representations(owner_id, kind, model, model_version, dimension, metric, normalization, sanitized_content_digest, sanitization_receipt_id)`. +- `facets(scope, time_bucket, kind, key, value, count, source_watermark)`. +- `rank_features(owner_id, lexical, semantic, recency, trust, graph, usage, version)`. + +Read-only retrieval never increments counters inside the query transaction. Retrieval and feedback are explicit events so replay/debug queries do not change future ranking. + +## 9. Query Platform + +### 9.1 One `TraceQueryV1` AST + +`TraceQueryV1` supports: + +- Scope: All, project set, project, repository, checkout/worktree, branch/ref, snapshot/commit, session, agent, workflow, initiative, plan, work item, execution attempt, executor, saved view/collection. +- Scope resolution policy: exact/resolve/related, explicit-target refusal, freshness/partial/as-of limits, and activity-attribution role. +- Entity kinds and typed attribute predicates. +- Time: occurred, ingested, valid/as-of, absolute/relative, comparison interval. +- Text: phrase, prefix, field, language/tokenizer, lexical profile. +- Semantic similarity with representation/model constraints. +- Relation traversal: direction, kinds, evidence classes, confidence floor, depth, path/neighborhood. +- Git/code predicates: file, symbol, snapshot, changed-by, affected-by, test/diagnostic state. +- Provenance, provider, model, role, kind, sensitivity, retention, policy version. +- Facets, grouping, aggregation, projection fields, sort, stable page size. +- Explain and sampling/downsampling controls. + +New operator families are added only through plan 19 §7.2's versioned query-operator SPI plus a `TraceQueryV1` schema revision; transports and projectors never introduce ad-hoc operators. + +### 9.2 Planner + +1. Resolve scope and permissions through the catalog. +2. Select shards from kind/time/scope/capability statistics. +3. Push filters, FTS, vectors, traversal, aggregation, and top-k into shards. +4. Enforce operator and total cost budgets before execution. +5. Normalize and merge scores with a declared ranking profile, initially reciprocal-rank fusion plus explicit feature weights. +6. Batch hydrate entities, provenance, and authorized payload slices. +7. Return a deterministic cursor containing per-shard high-watermarks, schema/ranking versions, sort cutoffs, and entity ID; never hold SQLite read transactions across pages. +8. Record a safe query-plan fingerprint and performance metrics without logging sensitive literals. + +### 9.3 Query response contract + +Every response contains: + +- Canonical resolved `ScopeSelectorV2`, catalog/scope-set generation, exact repository/worktree/ref/snapshot labels, and whether `current` was defaulted. +- Query snapshot/watermark and query-plan ID. +- Entities/rows/edges plus typed field projection. +- Facets and aggregation metadata. +- Next cursor and exact truncation reason. +- Searched, skipped, stale, unavailable, incompatible, and redacted shards. +- Sanitization policy/detector generation, locked/quarantined/legacy-unscanned/unknown privacy coverage, and only authorized safe receipt refs. +- Timing by planner/operator/shard. +- Ranking feature explanation per result when requested. +- Provenance/evidence summary. +- Sampling/downsampling/level-of-detail declaration. +- Location-independent entity/retrieval refs that exact-load tools accept across project shards without CWD/store switching. + +Cursor semantics: + +- Cursor expiry is explicit and uses plan 20's `query.cursor.interactive_ttl`, default 15 minutes; export/bulk continuations use their catalog-declared job lifetime. +- Schema/ranking change, retention crossing a captured watermark, or incompatible shard replacement invalidates the cursor with a restart reason. +- A shard that becomes unavailable during resume yields named partial coverage and preserves other shard positions. +- Frozen queries exclude events above captured shard watermarks. Live queries use delta cursors with duplicate suppression and explicit gap/resync events. + +### 9.4 Specialized services compiled from the same model + +- Universal search. +- Entity batch hydration and inspector. +- Neighborhood/path/impact/affected-tests queries. +- Timeline lane/density/event queries. +- Session replay and as-of state. +- Hint/retrieval/ingest/correlation/policy evaluation. +- Saved views, annotations, comparisons, exports. +- Live snapshot + ordered delta stream over SSE. + +### 9.5 Transport rules + +- MCP handlers parse arguments, call application services, and render results. They contain no SQL, routing, ranking, policy, or migration logic. +- CLI calls the same services in-process or through the daemon. +- CLI/MCP/API/SDK/dashboard bindings decode the same generated request schema, call the same use case, and expose identical semantic rows/order/scope/coverage/freshness/errors/effects. They differ only in transport framing and checked presentation. +- MCP human output defaults to compact Markdown; `format=json` is canonical typed semantic data, not a JSON-RPC envelope containing rendered JSON text. CLI `--json` selects that same semantic representation; transport debugging is separate. +- Human renderers consume sealed typed views through the pure presentation boundary. No raw `serde_json::Value` renderer, silent depth/array compaction, appended notice text, handler-local limit, or irreversible `compacted_no_handle` path survives. +- Every collection uses deterministic ordering, an authenticated opaque cursor, returned/total semantics, applied byte/token budgets, and a resumable retrieval anchor for oversized eligible content. Missing-registry, empty, partial, stale, locked, redacted, and unavailable states retain stable outer shapes. +- One typed outcome maps application error code, retryability, CLI exit code, MCP `isError`, HTTP status, analytics outcome, notices, metrics, freshness, and provenance; command modules never infer failure from rendered text or exit successfully after a semantic error. +- HTTP V2 uses typed bounded endpoints, not GraphQL as the primary surface. +- TypeScript contracts are generated from Rust schemas/OpenAPI and checked for drift. +- V1 endpoints/tools may shadow V2 only before that domain's cutover. At cutover the current catalog/protocol becomes authoritative; stale clients receive a typed version/restart/update/replacement error instead of a behavioral fallback. + +### 9.6 Message/session retrieval and real-world precision program + +[`tracedecay-v2/15-search-quality-evaluation-and-retrieval-research.md`](tracedecay-v2/15-search-quality-evaluation-and-retrieval-research.md) owns general retrieval research/evaluation; [`tracedecay-v2/23-session-lcm-temporal-retrieval-and-evaluation.md`](tracedecay-v2/23-session-lcm-temporal-retrieval-and-evaluation.md) owns the current message/LCM source audit, occurrence/copy/summary lineage, temporal truth, context assembly, and session replay gates. V2 does not replace BM25 with embeddings. It exposes a versioned multi-stage pipeline whose components can be ablated: + +1. Normalize Unicode, spelling variants, provider/tool aliases, code/Git identifiers, quoted phrases, and time/scope constraints without rewriting exact technical literals. +2. Generate independent candidates from phrase/BM25 FTS, character n-gram fuzzy matching, typed entity/event/goal/tool/Git indexes, session/agent/work-claim graphs, summaries with source coverage, optional privacy-safe local dense representations, and explicit recency. +3. Fuse declared retrievers with a deterministic profile such as reciprocal-rank fusion; retain every component rank/score and missing-feature state. +4. Cluster copied prompts, protocol/tool echoes, same-content variants, and summary/source lineage. Prefer a representative appropriate to requested audience/kind, preserve hidden counts, and expand to native rows exactly. +5. Apply diversity across sessions/projects/providers/agents while retaining exact phrase/entity hits. Penalize the current query/tool echo and inventory noise unless explicitly requested. +6. Optionally rerank a bounded top set with a versioned local cross-encoder or learned model only when measured gains justify latency/memory/privacy cost. Fall back deterministically. +7. Return rank explanation, matched fields/entities/relations, retriever contributions, cluster/representative reason, corpus/index/model versions, scope, caps, and coverage. + +After candidate recall, a temporal resolver applies explicit answer mode—`Current`, `Historical { as_of }`, `Evolution`, or `Forensic`—plus validity, correction/supersession/conflict relations, evidence authority, and scope before final ranking. Current mode prefers a supported replacement over a stale exact predecessor and links the history; historical mode admits no future evidence; evolution ranks change points; forensic mode minimizes hiding. Summary nodes are derived navigation documents with exact source ranges/horizons and can never independently prove a claim. + +The real-world evaluation corpus is sampled from the local registered-project store without committing private text: + +- Stratify across projects, providers, time, human/direct-user/subagent/protocol origin, exact versus paraphrase versus typo versus conceptual query, Git/code/tool/memory/automation intent, old versus recent sessions, short versus long messages, and known-zero-result cases. +- Derive leakage-resistant queries from later human prompts that refer back to earlier evidence; candidates must come only from data available before the query timestamp. +- Add real successful retrievals, user corrections, reformulations, abandoned searches, branch/PR/session lookups, and hard negatives from same-project terminology. +- Pool candidates from every retriever/ablation, blind their source/order, and label exact relevance plus “useful first context,” duplicate/echo/protocol noise, privacy eligibility, and required evidence class. Measure annotator disagreement instead of forcing false certainty. +- Keep private judgments locally with stable message/session/research anchors; commit only secret-scanned synthetic/redacted fixtures and aggregate metrics. + +Required offline metrics: Precision@1/3/5, Recall@10/20, MRR, nDCG@10, judged coverage, no-answer accuracy, duplicate/echo rate, project/provider/session diversity, first-useful rank/time, calibration, p50/p95 latency, peak memory, index size/build lag, and exact-query regression. Report macro averages and worst strata, not one global score. + +Required shadow/online evidence: reformulation rate, result open/expand/copy/use, retrieval-to-tool/action continuation, explicit helpful/unhelpful label, time to useful context, abandonment, and user correction. These are evidence signals, not automatic relevance truth. Interleaving/A-B is opt-in, privacy-safe, reversible, and never changes a live agent's context silently. + +Release selects a retrieval profile only if it beats the lexical baseline on predeclared primary metrics without violating exact technical recall, privacy, no-answer, latency, memory, or worst-project/provider gates. Dense, sparse-neural, reranker, and graph components remain removable adapters. + +## 10. HTTP V2 Surface + +HTTP V2 is an official supported public integration surface, not only a dashboard backend. Agents and developers may call it directly through authenticated loopback HTTP or a user-owned local socket, raw `curl`, or first-party Rust/TypeScript/Python SDKs. OpenAPI 3.1, JSON Schema, capability docs, examples, version/cutoff policy, direct-client discovery, conformance, and a hermetic sandbox are release artifacts. CLI and MCP share application/catalog semantics but do not loop through HTTP. Full ownership and rollout are specified in [`tracedecay-v2/17-official-public-api-and-sdks.md`](tracedecay-v2/17-official-public-api-and-sdks.md). + +[`tracedecay-v2/10-api-crate.md`](tracedecay-v2/10-api-crate.md) §8 is the only normative route/method/operation-ID inventory. It is generated from the plan-08 capability catalog and plan-09 use-case registry, then consumed unchanged by OpenAPI, SDKs, MCP/CLI bindings, dashboard clients, conformance tests, and migration dispositions. This master plan intentionally does not maintain a competing exact route list. + +The generated surface must cover these capability families completely: + +- discovery, protocol/schema/catalog negotiation, auth/token lifecycle, health, coverage, configuration, diagnostics, privacy, migration, projections, and subscriptions; +- scope resolution, universal/typed search, entity hydration, graph/timeline queries, sessions/messages/replay, retrieval anchors/recipes, research provenance, exports, saved views, and annotations; +- agents/nearby work, coordination, initiatives, immutable plans, work items, offers, packets, attempts, leases, executors, scheduler, task events, manual attestations/reviews/decisions/exceptions/handoffs/reopen/reversal, and notifications; +- memory/knowledge, autonomous curation, skills, automation, evolution, policy, hint/scout delivery, historical replay, playgrounds, and every read/write search-quality evaluation artifact; +- Git/code/delivery, costs/accounting, Observatory operations, and every operation-specific maintenance/recovery workflow. + +Every current writable dashboard workflow maps to one typed catalog command with idempotency, optimistic version checks, authorization, audit/effect receipts, and matching CLI/MCP/API/SDK/UI exposure. Destructive non-curation actions use operation-specific inspect/plan/start/recover contracts when meaningful. Autonomous curation remains internally revalidated and receipt-bearing without per-candidate preview/apply/rollback commands. + +Every non-curation command has typed execution/result/audit schemas, idempotency, optimistic version checks, scope, required authorization, and domain parity tests; destructive commands add an operation-specific immutable plan and separately authorized start when meaningful. Autonomous curation effects are internal idempotent transactions with equivalent policy/config/version/audit/outcome receipts but no per-item command. + +All mutations require idempotency keys, optimistic version checks, and an audit event. Destructive non-curation actions require confirmation/explicit execution when meaningful. Policy-eligible curation effects execute autonomously after transactional revalidation and never require explicit per-item apply. + +Local HTTP security is mandatory even on loopback: bind only to loopback by default; mint a per-launch bearer/session token; enforce strict `Host` and `Origin`; use CSRF protection for browser mutations; ship a restrictive CSP; contain export paths; and never place sensitive query literals or entity payloads in URLs. + +SSE is scope-filtered and authorized. It uses `Last-Event-ID`/sequence cursors, finite replay retention, heartbeat, backpressure/coalescing, slow-client termination, ordered resume, and explicit gap/resync events. The browser keeps last-known-good data, displays last-updated/stale/offline state, reconnects with backoff, repairs gaps, and handles out-of-order deltas idempotently. + +## 11. Product Information Architecture + +### 11.1 Routes + +- `/` — Brain / All. +- `/activity` — cross-project activity and operational pulse. +- `/explore` — universal query, pivots, collections, compare, export. +- `/timeline` — Causal Loom timeline explorer. +- `/sessions`, `/sessions/:id`, and `/turns/:id`; thread and Turn collections are `threads`/`turns` graph lenses over shared investigation state. +- `/agents` and `/agents/:id`. +- `/coordination` — nearby-agent presence, work claims, overlap, and safe actions. +- `/work`, `/work/initiatives/:id`, `/work/plans/:id/versions/:version`, `/work/tasks/:id`, `/work/attempts/:id`, `/work/executors`, `/work/scheduler`, `/work/views/:id`, and `/work/notifications`. +- `/goals/:id`. +- `/workflows/:id`, `/automation/runs/:id`. +- `/code`, `/code/entities/:id`, and `/code/compare`. +- `/graphs/:lens`, where the legal saved lens presets are `git`, `code`, `threads`, `turns`, `agents`, `tasks`, `plans`, `timeline`, `memory`, and `automation`. +- `/knowledge`, `/knowledge/facts/:id`, `/knowledge/entities/:id`. +- `/delivery`, `/projects/:id`, `/projects/:id/branches/:branch`, `/pulls/:id`. +- `/automations`, `/skills`, and `/evolution`. +- `/observatory` — health, ingest, storage, diagnostics, data quality, privacy. +- `/observatory/context-scout`. +- `/privacy`. +- `/costs` — tokens, latency, models, tools, savings, methodology. +- `/playgrounds/:lab` for `hints`, `retrieval`, `ingest`, `query`, `search-quality`, `scope-federation`, `correlation`, `coordination`, `orchestration`, `scheduler`, `memory`, `policy-diff`, and `privacy`; `/playgrounds/evolution` is the named fourteenth lab/workspace route. +- `/saved/:viewId`. +- `/settings` and `/settings/context-scout`. + +Project pages are saved filtered views of the same product.

Browser back/forward traverses investigation states, not just tabs. + +## 12. Brain / All View + +The default question is: + +> What is TraceDecay doing, learning, changing, and failing across all registered projects? + +### 12.1 Semantic zoom + +- **Level 0 — Profile:** projects/repositories as clusters; active initiatives/plans/tasks/attempts, sessions/agents/runs, blockers/leases/acceptance state; health; ingest lag; change, knowledge, automation, hint, and cost activity. +- **Level 1 — Project:** worktrees, branches, initiatives, plan versions, work items/dependencies, offers/packets/attempts/executors, sessions, workflows, automation, memory, code snapshots, and delivery. +- **Level 2 — Neighborhood:** selected entity plus typed, filtered evidence relations. +- **Level 3 — Evidence:** exact message, visible reasoning summary, tool event, diff, diagnostic, fact source, policy evaluation, artifact, or remote delivery record. + +### 12.2 Layout modes + +- Cluster/stress layout for cross-domain relationships. +- ELK layered layout for workflow/provenance DAGs. +- Radial distance-from-selection layout for impact/reachability. +- Adjacency matrix for dense topology. +- Searchable outline/table for precision and accessibility. + +The server returns clustered multiresolution tiles and bounded neighborhoods. The UI never tries to render “the whole brain” as a hairball. Positions remain stable across expansion and reload; aggregate edges may bundle, evidence-level edges do not. + +Every aggregate tile returns a truthful contract: stable cluster ID, exact membership/count or declared sample, source denominator, aggregated edge counts by kind/evidence, uncertainty/coverage, child availability, expansion cursor, snapshot watermark, and layout/community algorithm version. + +### 12.3 Default evidence + +The default reading path is not an equal-weight card grid: + +1. **First-scan claim:** a direct sentence describing the most consequential current activity or health issue, with scope/time/coverage. +2. **Central focal artifact:** recent active project/work/plan/task/attempt/workflow clusters linked to the selected event window, with blockers, leases, packet acceptance, and ownership visible before decorative topology. +3. **Subordinate evidence:** recent work/agent/code/delivery/knowledge/automation timeline aligned beneath the topology. +4. **Operational guardrail:** compact project × subsystem health strip with ingest/projection/privacy warnings. +5. **Feedback loop:** hint/tool/fact/skill/automation adoption and unresolved-outcome alerts. +6. **Resume:** ready/blocked/in-flight work, pending offers/reviews/decisions/handoffs, interrupted attempts, unfinished workflows, and saved investigations. + +Desktop presents focal topology plus aligned timeline; mobile defaults to the first-scan claim, focused recent cluster, and single-lane activity, with health/feedback/resume in sheets. The default selection is the newest consequential event in the most recently active healthy-enough scope; if data is partial, health/coverage becomes the selection instead. + +### 12.4 Graph-of-graphs lenses + +The Brain is best understood as coordinated graph lenses over shared identity, time, scope, selection, and evidence—not one universal node/edge soup: + +- **Git graph:** refs, worktrees, commits, trees, diffs, PRs, checks, reviews, releases, and encountered remotes. +- **Code graph:** repository snapshots, files, symbol lineages/occurrences, calls/types/uses, diagnostics, tests, ownership, and impact. +- **Thread graph:** sessions/threads, turns, messages, content/reasoning artifacts, context summaries, tools, goals, and workflow membership. +- **Agent graph:** actors, agent instances, parent/subagent creation, delegation, messages, handoffs, joins, interruptions, goals, and outcomes. +- **Task and plan graph:** initiatives, immutable plans/work-item versions, typed gates, acceptance, assignments, claims versus leases, attempts, executor routes, context packets, workspaces, artifacts, outcomes, critical path, and evidence links into every other graph. +- **Timeline graph:** occurred/ingested order, intervals, causation/correlation, concurrent lanes, late events, and as-of state. +- **Holographic memory graph:** facts/versions, entities, decisions, contradictions, source evidence, trust, retrieval, feedback, and curation. +- **Automation and skill graph:** jobs, schedules, Claude workflow runs, Codex goals, Hermes-style curator/reflector/skill-writer agents, candidates, artifacts, autonomy decisions, automatic effects, usage, outcomes, revisions/recovery, and clearly labeled historical approval/apply events. + +A `Turn` is a first-class interval/entity, not just a message index. Per-provider Turn boundary rules — what opens and closes a Turn — are owned by plan 23 §3.3. It owns the user/agent exchange boundary and links the context visible at its start, provider-exposed reasoning artifacts, messages, tools/results, file/code evidence, goals, hints/memory/retrieval, costs, and state produced by its end. Provider-native meanings are preserved: a Claude workflow run, Codex goal, host thread, and TraceDecay automation run are related canonical entities, not flattened into one ambiguous “run.” + +Selecting an entity in any lens keeps the same investigation state and reveals evidence-bearing cross-links into the others. Each lens has its own legal nodes, edges, layout, aggregation, and fallback table. The UI never implies that a memory-similarity edge, call edge, temporal correlation, and Git ancestry edge share the same semantics merely because all can be drawn as lines. + +## 13. Universal Explorer + +- Search across projects, messages, sessions, agents, workflows, initiatives/plans/tasks/attempts/executors, code, Git/delivery, facts, skills, automation, diagnostics, hints, costs, and artifacts. +- Text and structured query builder produce the same visible `TraceQueryV1`. +- Results pivot among table, timeline, graph, matrix, distribution, small multiples, and saved collection. +- Query Explain shows selected shards, pushed filters, budgets, ranking features, cache/projection use, stale/partial state, and timing. +- Command palette exposes existing MCP capabilities as guided query actions without requiring JSON copying. +- Every result opens the same universal inspector and can be added to a comparison or collection. + +## 14. Causal Loom Timeline + +### 14.1 Coordinated lanes + +- Human prompts and user-visible objectives. +- Assistant responses and provider-exposed reasoning summaries. +- Parent agent and spawned subagent lifecycles. +- Inter-agent messages, tasks, handoffs, goals, and plan updates. +- Tool calls, approvals, results, errors, retries, latency. +- Files, symbols, patches, diagnostics, builds, tests, affected-test selection. +- Worktrees, branches, commits, PRs, checks, reviews, releases. +- Hints, memory injection, retrieval, facts, feedback, policy decisions. +- Automation schedules, skips, runs, artifacts, curation candidates/autonomy decisions/automatic effects/recovery, plus labeled historical approval evidence. +- Tokens, context, compression, latency, cost, estimated savings. + +### 14.2 Reading model + +- Overview density strip for months/days/runs. +- Zoomable event waterfall for runs/turns/events. +- Virtualized transcript/code/diff inspector. +- Stable parent/subagent tree and lane ordering while zooming. +- Routine tool noise collapses; consequential events remain visible. +- Selecting a time window derives touched files/symbols/tests/commits/PRs/facts/hints/automations with evidence labels. + +Lane level-of-detail rules are part of the API contract: + +- Density bins report exact or sampled count, denominator, hidden-event count, source coverage, late-event count, and aggregation version. +- Consequential classes—human prompt, agent spawn/handoff, failed tool, file mutation, diagnostic/test failure, commit/PR/review/release, policy mutation, privacy event—remain discoverable at every zoom. +- Collapsing routine noise never removes it from counts or export; the UI shows hidden counts and expands deterministically. +- Late-arriving events are placed by occurred time and marked by ingested time; a frozen view never silently reorders. +- “Touched” means a direct structured event.

Motion represents activity, traversal, recency, or state transition. +- Essential values remain visible without hover. Hover previews; committed selection updates URL/history/inspector. +- Direct labels beat detached legends. Color is redundant with shape, line, icon, or text. +- DOM/SVG target: fewer than about 2,000 visible marks. Canvas for dense 2D. WebGL for genuinely large graph/timeline selections. +- Server clustering/aggregation precedes transfer. Viewport/time-window queries and worker-based layout avoid main-thread stalls. +- Layout caches are deterministic by query snapshot and preserve positions during expansion. +- Every graph has synchronized searchable outline, relationship list, selected-path text, and data export. +- Reduced motion freezes layouts after deterministic settle and replaces animation with static recency/state encodings. +- Every substantial visual has a checked-in mini-brief: analytical job/claim, data grain, encoding, interaction states, mobile continuation, URL/saved state, fallback, accessibility, export scene, QA fixture, and approved desktop/mobile concept contract. +- Shared semantic color ledger: neutral context, primary focus, comparison, selection, alert severity, stale/partial/offline, sensitivity, and evidence class. One color has one meaning across views; shape/line/icon/text remains redundant. Contrast, grayscale, and color-deficiency fixtures are required. +- Mobile portrait uses focused neighborhoods and one primary timeline lane with step-through controls; landscape enables coordinated graph/timeline. Tap/focus replaces hover, 44–48 px targets are required, pinch/wheel ownership and `touch-action` prevent scroll traps, and explicit zoom/reset/step controls provide gesture alternatives. +- Renderer throughput is not permission to show a hairball. The 50k graph benchmark means loaded/GPU-managed entities; labeled/interactive topology is capped by LOD, crossing/overlap/selection legibility budgets. Timeline benchmarks distinguish density marks from inspectable events. + +## 18. Frontend Architecture + +### 18.1 Proposed packages + +- `dashboard/app/` — route shell and composition root. +- `dashboard/packages/contracts/` — generated V2 client/types. +- `dashboard/packages/query-state/` — URL/saved-view schema, codecs, selection/time/scope state. +- `dashboard/packages/design-system/` — tokens, typography, controls, panels, tables, empty/loading/stale/partial states. +- `dashboard/packages/inspector/` — universal entity/event/evidence inspector. +- `dashboard/packages/brain/` — semantic-zoom graph/matrix/outline. +- `dashboard/packages/timeline/` — density, lanes, virtualized transcript, time brush. +- `dashboard/packages/charts/` — ECharts ownership, direct-label and accessibility helpers. +- `dashboard/packages/code-viewer/` — CodeMirror code/message/diff payloads. +- `dashboard/features/*` — Brain, Explorer, Work/Plans/Tasks/Executors, Sessions, Agents, Code, Knowledge, Delivery, Automations, Observatory, Costs, Playgrounds. + +Before selecting the new dashboard bundler, commit an ADR comparing the current Rsbuild/plugin asset pipeline with Vite: dev/prod build, embedded Rust assets, code splitting/lazy routes, CSP, base paths, source maps, legacy plugin loading, test tooling, and migration cost. React/TypeScript and package boundaries are fixed; the bundler follows the ADR evidence. + +### 18.2 Ownership rules + +- Feature modules request typed read models; they never join raw endpoints in the browser. +- Query state is shared; renderer-local transient state is not global. +- Each renderer owns one canvas/WebGL instance and exposes selection/camera/accessibility adapters. +- Hidden views pause layout/render loops. +- Every feature has loading, empty, stale, partial, offline, incompatible, redacted, and error states. +- Each old plugin retains its existing read/write behavior until that domain's V2 query and command parity gate passes. It then redirects to V2 and retires independently; no blanket read-only downgrade. + +## 19. Privacy, Security, and Retention + +### 19.1 Sensitivity classes + +- Metadata-only. +- Normal content. +- Sensitive content. +- Secret-like/quarantined. +- Reasoning. +- Redacted-derived. + +### 19.2 Rules + +- Local-only and no network upload by default. +- Managed files and blobs are private (`0600` where applicable), root-contained, and hash-verified. +- Classify/redact before FTS, vectors, facts, fixtures, or remote integration. +- External embeddings require per-scope consent; local embeddings are default. +- Raw originals are retained only when policy allows; protected mode encrypts blobs. +- Reasoning has opt-in capture, shorter default retention, and export/index exclusion by default. +- GitHub/remote delivery integration is read-only by default and repository-allowlisted. +- Exports include schema versions, source coverage, redaction report, hashes, and generation time. +- Deletion flow: create immutable descendant-impact retirement plan → separately authorize start → tombstone canonical entity → rebuild/remove projections → release blob refs → GC → retain non-content audit receipt. +- Legal/pinned holds prevent deletion and are visible in the retirement plan. + +The privacy ADR committed before the observation journal fixes these initial defaults: + +- Normal human/assistant message content: retained until explicit user policy/delete, preserving TraceDecay's local history mission. +- Provider-exposed reasoning artifacts: 30 days unless explicitly pinned; excluded from FTS, vectors, facts, shares, and exports by default. +- Secret-like/quarantined raw payload: 24 hours for local inspection, never indexed, then content deletion with tombstone. +- Reconstructable response handles/cache: 7 days. +- Raw analytics/hook telemetry: 180 days; nonsensitive aggregate rollups may persist. +- Reconstructable automation intermediates: 90 days unless pinned by a run/artifact policy. +- Tombstone/provenance skeleton and deletion audit receipt: retained without deleted content. +- Protected mode: optional for local V2 compatibility, mandatory before any non-loopback/team exposure. Key lives in the OS keyring; rotation rewraps per-domain keys; encrypted recovery export is required before destructive rotation. +- Locked store: metadata/coverage remains visible, payload/search projections stay unavailable and explicitly locked. +- Deletion SLA: canonical tombstone and FTS/vector removal within one minute; blob ref release immediately; physical blob GC after the 24-hour recovery grace. + +Every response/export includes the evidence-retention watermark. Historical replay beyond retained inputs is explicitly incomplete. + +### 19.3 Zero-secret ingress, indexing, fixture, and release gate + +Secret detection is a mandatory boundary before any content becomes generally queryable or distributable. It combines versioned deterministic credential/key/token patterns, structured credential/config parsers, provider-native redaction markers, entropy checks with calibrated context, and user/project allow/deny rules. Scanner findings are data-classification inputs, not content to paste into logs or reports. + +Hard invariant: secret or unadjudicated secret-like bytes never enter FTS, dense/learned-sparse representations, graph labels, summary DAG text, facts/memories, skills, hint context, query/rank features, caches/response handles, analytics, logs/traces/errors, cursors/anchors, dashboard/browser storage, source maps, fixtures/snapshots, examples/docs, exports/shares, eval/qrel corpora, or generated SDK/API artifacts. Secret detection runs before those sinks and again at every promotion/export/release boundary. + +Raw-source handling: + +- Lossless provider source remains provider-owned. TraceDecay stores only a privacy-domain-bound locator digest, keyed source fingerprint with key epoch, and source offset/position plus a redacted observation unless policy explicitly permits a protected forensic copy; no unkeyed source/content hash is persisted. +- A permitted secret-like forensic payload is encrypted inside a separate quarantine/key domain, never indexed/deduplicated outside that domain, mode-private, access-audited, and deleted after the initial 24-hour retention unless the user explicitly places a hold. +- Safe projections contain fixed redaction markers and span/reason receipts, never enough prefix/suffix material to reconstruct the secret. +- False-positive adjudication records rule/version/class and safe digest only; it does not copy the matched value. Allowlisting is narrow to an exact safe digest/context and cannot disable a rule profile-wide silently. + +Fixture and Git gate: + +- No database, store, transcript, provider payload, response cache, or user export is copied directly into a fixture or PR. +- Fixture promotion selects the minimum slice, structurally redacts it, substitutes synthetic identifiers/content, scans the slice plus manifest/generated snapshots/source maps, and records scanner versions/policy digest/zero-findings receipt. +- CI scans the staged diff, repository history introduced by the PR, archives, generated API/SDK/docs/frontend assets, test snapshots, and release packages with a pinned secret scanner plus TraceDecay's versioned classifier. A finding blocks commit/release until removed or narrowly adjudicated without exposing the value. +- Canary tests seed synthetic secret classes through every input and assert zero occurrences in every forbidden sink, including post-deletion/rebuild/backup/export paths. + +Retroactive V1/V2 audit and repair: + +1. Inventory every store, blob, payload cache, FTS table, representation segment, fact/skill/automation artifact, fixture, export, log, backup, and generated frontend/API/package artifact without rendering content. +2. Scan in the owning privacy domain; persist only safe finding class, entity/blob digest, detector version, owning domain, state, and remediation receipt. +3. Immediately prevent flagged content from query/hydration/export; show a redacted/quarantined coverage state. +4. Tombstone/redact canonical content, rebuild FTS/vector/summary/fact/graph/cache projections from redacted observations, release blob refs, rotate credentials when real exposure is confirmed, and invalidate exports/caches/anchors that could reveal content. +5. Scan backups and rollback stores before they are eligible for restore; an unsafe legacy store remains quarantined rather than becoming a compatibility source. +6. Verify zero canary/known-secret digest hits across all forbidden sinks and record unexplained/locked/unscanned coverage. “Zero findings” is never claimed when a domain was skipped. + +Current planning evidence: `gitleaks 8.30.1` found zero findings in the plan set and sanitized private corpus. The first pass produced four marker-only private-key-rule findings across transcript rows; no complete key block or long key body was present. Parsed-value sanitization conservatively replaced 47 credential-shaped/marker/example occurrences in the user corpus and four assignment-shaped examples in the human subset. A permissive authenticated-URL alert over serialized JSON was reclassified as a cross-field false positive after parsed-field validation. Canonical corpus files were replaced with their sanitized versions, remain outside Git and mode `0600`, and are not committable fixtures. + +## 20. Reliability and Operational Model + +- Corrupt/missing/incompatible shards return named partial coverage, not silent omission or total dashboard failure. +- Catalog rebuilds from manifests and outboxes. +- Projections replay from immutable observations/events. +- FTS, vectors, rollups, and graph analyses rebuild independently. +- Blob doctor verifies hashes, references, permissions, missing files, and orphans. +- Shard quarantine keeps unaffected projects queryable. +- Backups consist of catalog manifest, project shard snapshots, graph snapshot manifests, and blob inventory. +- Recovery drills kill processes during observation commit, outbox commit, projection, blob staging, graph swap, migration, retention, and GC. +- Every migration has disk-space preflight: old data + new data + 25% headroom. + +## 21.

Locked architectural decisions + +- Start as one Rust binary with bounded internal crates/ports; allow later daemon/query split without changing contracts. +- Use one profile catalog, one canonical profile activity journal/projection, project/privacy-domain shards, immutable packed graph generations, and privacy-domain content-addressed blobs. +- SQLite/rusqlite is the initial local engine; libSQL/remote federation is a future evaluated option, not an assumption. +- Capture immutable sanitized-native observations before canonical projection; retain keyed source fingerprints/offsets/parser versions and unknown sanitized fields. Sanitize-before-persist is mandatory; no raw source hash of secret-bearing content is stored. +- Run one mandatory parse-before-scan sanitizer before the observation journal; secret plaintext never reaches general stores/indexes/outputs, while optional protected raw retention is isolated/encrypted/short-lived. +- Model bitemporal evidence relations and confidence/provenance; never convert correlation into causal language silently. +- Provider-visible reasoning summaries may be retained according to sensitivity/retention; hidden chain-of-thought is neither captured nor reconstructed. +- Sessions/agents/Turns live canonically in profile activity. Repository/project/worktree attribution is temporal evidence, not one provider key. +- `ScopeSelectorV2` is shared across every surface. Explicit targets never fall back to current CWD/project/ref. +- Search is hybrid and measured: exact/phrase/BM25 first, bounded fuzzy/entity/graph/dense/learned-sparse/rerank channels only when they improve labeled gates. +- Retrieval IDs route globally to exact retained evidence; expiring response handles are never sole citations. +- Hooks remain bounded and local: no synchronous federated fan-out, embeddings, indexing, automation, or long writes. +- Hints optimize useful action and useful silence, not volume; nearby-agent hints are compact, evidence-scored, deduped, and non-authoritative. +- Tool/capability definitions generate CLI/MCP/API/dashboard/skill/hint bindings and drift tests from one catalog. +- Application services own behavior; transports are thin adapters and frontend uses generated client types. +- Official API is supported, versioned, documented, locally authenticated, bounded, and usable directly by agents through Rust/TypeScript/Python SDKs. +- All/Brain is the product default; project views are zoomed scopes inside one system. +- Every visualization has table/outline/export/accessibility parity and explicit evidence/coverage semantics. +- Replay labs are read-only by default and do not contaminate analytics, facts, claims, policies, hints, or live coordination. +- Fact/memory/managed-skill/profile curation is fully autonomous under versioned configuration: deterministic validation/policy -> transactional effect -> outcome monitoring -> automatic revision/recovery. No per-item preview/approve/apply/rollback queue exists; UI/CLI provide configuration, pause/resume/run-now, pin/protect/exclude, feedback, and history. +- Migrate and retain non-disposable V1 data for rollback; do not emulate stale running clients, old protocol behavior, or obsolete tool names after cutover. +- One canonical owner/contract exists for identity, scope, privacy, capture, projection, query, policy, capability, application, and transport semantics; compatibility adapters have deletion PRs and cannot accept new call sites. +- One generated typed configuration registry and application resolver owns every user-controllable non-secret setting, precedence rule, effective source, impact, history, and runtime acknowledgement. All settings—including redactor/privacy and autonomous-curation policy—are navigable/editable in Brain Settings and generated CLI; secrets remain opaque references and the safety floor cannot be weakened. +- One generated capability/binding manifest owns every CLI/MCP/API/SDK/dashboard/hook/skill name, request/default/scope/effect/output/error contract, help entry, availability state, and compatibility cutoff. MCP defaults to compact Markdown, machine callers request canonical typed JSON/NDJSON explicitly, and all human renderers consume sealed typed views rather than raw JSON. +- The optional daemon Context Scout consumes canonical Turn/task/agent events asynchronously, performs only catalog-authorized bounded reads, optionally uses a capability-selected model such as Spark, and emits at most one evidence-anchored suggestion to an exact Thread/Turn through the shared hint selector. Hooks never wait for its model/tools; useful silence, privacy, expiry, dedupe, and replay gates dominate recall. +- Session/LCM retrieval distinguishes immutable occurrences, logical copies, summaries, and temporal assertions. Recency is one explained intent feature, not truth; explicit later corrections/supersession and authority determine current answers, historical/as-of replay has zero future leakage, and uncertain conflicts remain visible. +- One profile-owned federated initiative/plan/task graph is canonical. It is a native TraceDecay product produced by porting proven Hermes Kanban behavior/code where suitable and redesigning it where V2 can do better—not an adapter to a Hermes task service. Plan 13 PR 2A must pin the exact upstream/local commit, file spans, tests, license notice, and `direct_port|behavioral_port|redesign|drop` disposition before implementation code moves. Boards are canonical `TraceQueryV1` plus layout/grouping/policy projections; they never create or copy task identity, dependencies, advisory claims, attempts, leases, or authority. A task may appear in any number of project, repository, worktree, agent, executor, timeline, Kanban, DAG, or initiative views. +- Executor selection is explicit and typed: host/provider/model/reasoning effort, tool and effect grants, privacy/egress class, cost/time budgets, retry/concurrency policy, and availability resolve to an immutable route receipt. Codex, Claude, Cursor, Hermes, and future executors are adapters, not task owners. +- Every dispatched attempt acquires one compare-and-swap `TaskLeaseV1` with TTL/heartbeat, artifact/worktree overlap set, idempotency key, and unforgeable fence proof. `WorkClaimV1` is advisory nearby-work evidence only. Completion/cancellation revokes stale lease authority; dependency readiness comes only from current canonical edges. +- Versioned context packets bind task revision, scope, dependency outcomes, exact Thread/Turn anchors, code/Git/PR state, relevant advisory work claims and the authoritative attempt/lease, retrieval/config versions, source watermarks, visibility policy, budget, and digest. Agents receive only materially relevant, recipient-authorized sibling summaries; neither boards nor long threads become implicit context. +- `tracedecay-code-index` is the sole production owner of code extraction, grammar registration, watcher intake, incremental reuse, generation construction, lineage, and diagnostic/test attribution. Packed generations reference plan-02 privacy-domain blobs; they never embed a second source-body store. +- Metric definitions, surface codes, denominators, caps, horizons, pricing/savings methods, and SLOs are registered/versioned contracts. `unknown`, `partial`, and `capped` never render as known zero, and observability cannot create a second event/accounting path. + +## 5.

Plan 20 owns configuration product semantics and the registry/resolver contract; this crate owns only the pure config IDs, values, provenance, version, impact, and schema primitives that contract names. Plans 22–23 own scout/temporal product semantics while this crate owns their exact IDs, addresses, occurrence/copy/summary/assertion/answer-mode/envelope schemas, and reason-code registries. + +| Boundary | Contract | +|---|---| +| Enters | ADR-locked identity/privacy/scope/evidence semantics and safe primitive values; no provider bytes, I/O handles, ambient state, or transport JSON. | +| Exits | Versioned pure value types, validators, canonical encoders, schema/predicate registry, JSON Schema, and fixture digests. | +| Upstream owner | Master plan and cross-cutting plans 16–19 own product semantics and global phase gates. | +| Downstream owners | Store persists; capture constructs sanitized observations; projectors derive canonical evidence; query plans; policy evaluates; application applies; catalog/API/UI generate or render. | +| Extension seam | Add a versioned registry entry/type plus ADR, golden canonical encoding, migration mapping, privacy eligibility, and generated-schema update; never add a transport-local enum or string alias. | +| Scale/concurrency | Values are immutable and bounded; independent shard/source progress is a vector watermark; no process-local identity or global scalar sequence. | +| Migration/retirement | V1 values enter only through typed import evidence. Once all consumers use generated V2 schemas and parity receipts pass, duplicate V1 model modules are removed rather than wrapped indefinitely. | + +## Non-goals + +- No SQLite, `rusqlite`, `libsql`, SQL strings, paths, file permissions, locks, queues, threads, async runtime, or clock access. +- No source parsing, provider normalization, redaction engine, identity resolution, projection, ranking, query execution, cursor signing, encryption, or blob I/O. +- No V1 type aliases that expose V1 strings as V2 IDs. +- No hidden reasoning representation. `ReasoningArtifact` represents only provider-exposed material and always carries visibility and format. +- No global total order across independent sources or shards. +- No remote libSQL adapter or multi-tenant authorization model in the first V2 default. + +## Authoritative ownership decisions + +1. `activity.db` owns provider transcript observations, canonical sessions/messages/content parts, actors, agent instances, tool activity, goals, workflows, handoffs, cross-project activity search, session-to-project relation assertions, and profile/zero-project/cross-project knowledge, skills, policies, automations, saved-view content, and annotations. +2. `project.db` owns repository/project observations, Git/delivery evidence, project-scoped knowledge/policy/automation, project search projections, and opaque activity locators; it never copies canonical message content. +3. Scope-sensitive kinds require an explicit `DeclaredScope`; they are never forced into an arbitrary project or duplicated when reused across projects. +4. `catalog.db` owns profile/global allocations, shard metadata, health/capabilities, safe aggregate statistics, opaque locators, migration receipts, and outbox/projection watermarks. It cannot contain message text, query literals, annotations, raw paths classified as sensitive, or project payloads. +5. Graph generations own immutable snapshot occurrences and edges. Project rows point to explicit `CodeSnapshotId` and `GraphGenerationId`; a physical generation is never an entity identity. +6. Blobs are addressed inside a `BlobDomainId` composed from privacy domain, encryption-key epoch, and retention class. Deduplication never crosses that boundary. +7. An event has one owning shard and zero or more project-attribution relation assertions. Canonical activity never has a required primary `project_id`. + +## Current V1 seams and migration inputs + +| V1 seam | Current symbol or file | V2 treatment | +|---|---|---| +| Path-derived project identity and layout | `src/storage.rs`: `EnrollmentMarker`, `RepositoryIdentityMarker`, `ProjectIdentity`, `StoreLayout`, `GraphScopeId`, `default_profile_project_id` | Import strings as aliases/evidence.

Preserve split identities as candidates until parity resolves them. | +| Global registry plus activity monolith | `src/global_db.rs`: `CodeProjectRecord`, `ProjectAliasRecord`, `StoreInstanceRecord`, `GraphScopeRecord`, `SessionRecord`, `SessionMessageRecord`, `ParseOffset`, `GlobalDb` | Split canonical activity from project/catalog data. Import row identity only as provenance; canonical UUIDs come from deterministic keys or allocation ledger. | +| Graph schema/migrations | `src/db/migrations.rs`: `LATEST_VERSION`, `create_schema`, `migrate`; `src/db/connection.rs::Database` | Map nodes to snapshot occurrences and stable symbol entities. V1 schema version and database hash become import-manifest fields. | +| Session/provider types | `src/sessions/mod.rs`, `src/sessions/shared.rs`, `src/sessions/source.rs`, provider modules under `src/sessions/` | Capture adapters translate these into `ObservationEnvelopeV1`; provider-native identifiers remain aliases and provenance. | +| Session-origin classification and copied-prompt representatives | merged PR #410: `src/sessions/message_noise.rs`, message search/LCM query filters, CLI/MCP schemas and regressions | Model native row, origin classification (`direct_user`, `subagent`, `tool_result`, protocol/unknown), representative membership, and derivation evidence separately. Raw observations are never deleted by representative views. | +| Duplicated LCM message model | `src/sessions/lcm/types.rs`, `src/sessions/lcm/schema.rs::LCM_SCHEMA_VERSION`, `ensure_lcm_schema` | Canonical content stays in activity entities/events; LCM DAG and compression state become derived lineage projections with explicit source coverage. | +| V1 retention semantics | `src/retention.rs`: `RetentionConfig`, `RetentionTable`, `prune_table` | Preserve the strict “older than cutoff” boundary, but use required `ingested_at` as the V2 retention anchor and retain tombstone/provenance skeletons. | +| Hermes legacy consolidation | merged PR #407: historical `src/migrate/hermes.rs`: `LegacyHermesMigration`, `MigrationMarker`, `migrate_legacy_hermes_stores`, fact/session copy functions | Import `~/.hermes` only as a source. Sessions/LCM and profile/zero-project/cross-project or unresolved facts/skills/policy/automation land in activity; explicitly project-scoped equivalents land in that canonical project shard. The migration ledger and logical source fingerprint are parity evidence. | +| Runtime drain and lifecycle serialization | merged PR #412: `src/lifecycle_lease.rs`, daemon/service/update shutdown changes | Model lease epoch, drain intent, writer quiescence, checkpoint completion, service state, and shutdown receipt as distinct typed evidence. A restart/update may not imply writers drained or WAL checkpointed without the receipt. | +| Foreign managed-skill ownership and remediation | merged PR #411: `package_is_foreign_to_installation`, `SkillDrift::ForeignOrphan`, doctor/removal agreement | Model installation owner, scope, drift classification, severity, and remediation capability separately. A foreign/legacy package is informative evidence and cannot receive a destructive/update remediation owned by another installation. | + +Planning began at `99ad19bc`.

Immediately before PR 4, regenerate the exact crate/schema/protocol/tool inventory from current master and classify every newly merged/open PR. Accepted identity, edit, routing, catalog, retrieval/accounting, release, split-store consolidation, branch/session preservation, lifecycle, registry-healing, FTS-maintenance, graph-checkpoint, and restart-safe retirement behavior remains fixture input, not a frozen source-layout assumption. + +Merged PR #425 (`de3d05dc`, final head `d3bb28b5`) is not merely CLI implementation detail. V2 domain contracts preserve its safety invariants for consolidating two non-empty profile/store authorities: immutable source-manifest identities; canonical platform store locators; frozen snapshots for both SQLite families; holder identity by path plus file/inode and write-reservation evidence; two independently verified backup refs; deterministic confirmation recomputed under locks/reservations; append-only restartable ledger/checkpoints; identity-allocation/remap records whose LCM summary/source edges retain remapped source IDs; exhaustive row/payload/LCM/fact/feedback/branch/sentinel verification; and a cutover receipt constructible only after every proof passes. Failure, cancellation, or restart before that receipt leaves both inputs and authoritative selection unchanged. These are general migration/identity contracts consumed by plans 02/09/12/20/21, not permission to expose raw paths, holder details, or confirmation material in ordinary output. + +## Proposed crate tree + +```text +crates/tracedecay-domain/ +├── Cargo.toml +├── src/ +│ ├── lib.rs +│ ├── error.rs +│ ├── id.rs +│ ├── source.rs +│ ├── ownership.rs +│ ├── entity.rs +│ ├── time.rs +│ ├── privacy.rs +│ ├── retention.rs +│ ├── replay.rs +│ ├── protocol.rs +│ ├── payload.rs +│ ├── provenance.rs +│ ├── observation.rs +│ ├── event.rs +│ ├── message.rs +│ ├── coordination.rs +│ ├── relation.rs +│ ├── registry.rs +│ ├── policy/ +│ │ ├── mod.rs +│ │ ├── bundle.rs +│ │ ├── evaluation.rs +│ │ └── outcome.rs +│ ├── hooks/ +│ │ ├── mod.rs +│ │ ├── request.rs +│ │ └── receipt.rs +│ ├── ordering.rs +│ ├── watermark.rs +│ ├── command.rs +│ └── query/ +│ ├── mod.rs +│ ├── scope.rs +│ ├── predicate.rs +│ ├── text.rs +│ ├── semantic.rs +│ ├── relation.rs +│ ├── time.rs +│ ├── traversal.rs +│ ├── aggregate.rs +│ ├── sort.rs +│ └── cursor.rs +└── tests/ + ├── id_contract.rs + ├── ownership_contract.rs + ├── observation_contract.rs + ├── message_origin_contract.rs + ├── coordination_contract.rs + ├── policy_hook_contract.rs + ├── relation_registry_contract.rs + ├── retention_contract.rs + ├── ordering_watermark_contract.rs + ├── query_contract.rs + ├── schema_contract.rs + └── fixtures/ + ├── observation-envelope-v1.json + ├── relation-assertion-v1.json + ├── trace-query-v1.json + └── schema-digests.json +``` + +File ownership is strict: + +- `id.rs` defines UUID/hash newtypes and deterministic derivation only. +- `source.rs` defines normalized source identity, source position, rewrite generation, and missing-time reason. +- `ownership.rs` defines profile/shard/privacy/blob domains and the activity-versus-project decision table. +- `entity.rs` defines entity kinds, entity references, versions, deterministic keys, and allocation requests. +- `time.rs` defines UTC microsecond timestamps, half-open intervals, bitemporal bounds, and stable display ordering. +- `privacy.rs` and `retention.rs` define the sole sensitivity, sanitization receipt, taint-state, sink-eligibility, marker, and deletion-eligibility vocabulary without detecting, redacting, storing, or deleting content.

The sanitizer alone can consume `Unclassified` content into move-only `ProtectedQuarantineIngress`; it cannot serialize, clone, display, log, index, or cross a general repository/transport port. `ProtectedSecretRef` and `ProtectedQuarantineAttachmentV1` have no `Display`, public `Serialize`, clone, equality-across-domain, search, prompt, export, or ordinary blob conversion. Only `ObservationJournal::append_transaction` may consume an attachment token into its matching non-content quarantine skeleton; an unused attachment expires inside the protected service. `PayloadRef` always names sanitized bytes and binds its receipt; protected forensic content uses the separate quarantine port from Plan 18, never `PayloadRef`. + +Architecture/compile-fail tests forbid raw `String`, `serde_json::Value`, `Vec`, `Bytes`, or slices at application-to-store, projector-to-index, policy-to-hint, and application-to-transport content ports.

TTL controls current visibility, not historical deletion. `SafeCoordinationSummary::try_from_classified` rejects control characters, values longer than 160 Unicode scalar values, and any value not already classified catalog-safe; it never truncates or redacts a raw prompt. Missing safe text remains `None`. Retrieval anchors contain canonical IDs plus digests and safe source positions, never prompt/query/path excerpts.

`locked`, `redacted`, and `truncated` are empty. `skipped` contains only shards proven irrelevant by scope pruning; any unproven disposition sets `unknown_coverage`. Consumers must call this derivation instead of inventing a `complete` field. + +`ScopeSelectorV2` is the only public scope selector across query, commands, policy, catalog, capture, hooks/application, labs, exports, saved views, and coordination. `roots` must be nonempty; `exclude` can only subtract from resolved roots. `CurrentInvocation` and `AllAuthorized` are explicit roots, never meanings assigned to an empty vector. Human locators are typed, sanitized inputs inside the same selector and resolve to a canonical-selector echo in `ScopeResolutionV2`; no transport invents `project_key`, `project_path`, or stringly `all` semantics. Multi-repository/project/checkout/worktree/ref/snapshot/graph-generation selection is first-class. Resolution never falls back to CWD, `sessions.project_key`, the first Claude CWD, active base checkout, current branch graph, ignored-dependency hint scope, or a stale registry row. Ambiguity is an error or returned candidate set according to the selector, never “pick first.” Each selected code candidate is the explicit repository/checkout/worktree/ref/snapshot/generation tuple actually opened; refs may share a generation, and no ref name owns a database. Core resolution reports selected/candidate/missing/stale/unavailable/quarantined stores plus registry/index/ref watermarks and whether current invocation was deliberately defaulted. Application/query responses join separately authorized cross-project session/activity relation evidence without mutating or narrowing the selector. + +Query validation rejects page size above 1,000, unbounded traversal, traversal depth above 5, missing total/operator budgets, text/semantic predicates against secret or reasoning content without an explicit authorized filter, and unregistered attributes/predicates. Interactive cursor expiry comes from plan 20's `query.cursor.interactive_ttl` descriptor (default 15 minutes); export/bulk continuations use their catalog-declared job lifetime. Registry/ranking changes, retention crossing the snapshot, or incompatible shard replacement yield a typed restart reason. Commands require idempotency and compare-and-swap aggregate version; a conflict returns current version without applying the command. + +`TemporalClauseV1` is the only temporal answer-mode carrier: an absent clause means `Current`, and `AsOf` requires both the valid-time and knowledge-time cutoffs (plan 05 §11.4). Plan 05 plans and executes the clause; plan 23's session/LCM retrieval rides it, and plan 05 specifies the registered-attribute mapping for plan 23's filters — no parallel temporal AST or second answer-mode enum exists. `CursorClaimsV1` binds the resolved scope digest, catalog generation, temporal clause, intent-profile version, and partial-shard dispositions exactly as issued; plans 16/17/21/23 cite these fields rather than restating binding lists. Its digest fields are authoritative types: every adapter (including plan 05's private `CursorV1` encoding) must reuse `PrivacyDomainBoundLocatorDigest`, `AccessPolicyDigest`, and `ManifestDigest` unchanged — an unkeyed `ContentDigest` of query or access material is forbidden by the keyed-digest rule above. `CoverageReportV1` is the one shared coverage vocabulary for query/export/replay responses: plan 05 produces it, plans 07/09/10/13/17/20/22 consume it under this exact name, and `unknown_coverage: true` is mandatory whenever any shard's disposition cannot be proven — coverage never silently reads as complete. + +Task/plan/executor reads also use this exact `TraceQueryV1`. `EntityKind`, registered `AttributePredicate`, bounded `TraversalPredicate`, facets/aggregates/projection/sort/page/snapshot fields, and `TemporalClauseV1` express task sources and operators. No `TaskQuery`, `TaskSource`, pipeline DSL, task-local scope/as-of/page/sort/projection carrier, or saved-view scope copy is a public contract. A task-specific facade may only build and canonicalize a `TraceQueryV1` losslessly; saved task views persist that one AST and derive scope from `TraceQueryV1.scope`. + +## Cross-crate consumes/produces contracts + +| Consumer | Consumes from domain | Produces for other crates | +|---|---|---| +| `tracedecay-store` | IDs, ownership, allocations, observations, events, relations, registries, retention, watermarks, command envelopes | Persisted allocations, append receipts, shard/vector watermarks, migration/import receipts | +| `tracedecay-capture` | source keys/positions, unclassified/classified/sanitized wrappers, receipt and observation contracts | Sanitized observations, receipts, deterministic IDs, and optional protected-quarantine references through a separate port | +| `tracedecay-projectors` | events, relations, registry, watermarks | Registry-valid entity versions and projections | +| `tracedecay-code-index` | code snapshot/generation/symbol/evidence IDs, scope resolution, sensitivity/retention, and sink-eligible text | Deterministic extraction/build/lineage/attribution rows consumed only through the projector-owned build port | +| `tracedecay-query` | `TraceQueryV1`, cursor claims, scopes, predicates, evidence, watermarks | Signed cursor and query response types owned outside this crate | +| `tracedecay-policy` | immutable input refs, policy entities, evidence/retention | Versioned evaluation events/relations | +| `tracedecay-hooks` | hook request/receipt identities, safe coordination and suggestion envelopes, protocol/catalog refs | Bounded host events and delivery receipts submitted through application/capture ports | +| `tracedecay-tool-catalog` | capability/use-case/binding/presentation IDs, schema refs, effects, and safe registry values | Generated catalog/schema artifacts consumed by adapters and presentation | +| `tracedecay-application` | commands, queries, entity/evidence contracts | Use-case results rendered by adapters | +| `tracedecay-presentation` | sink-eligible/log-safe values, canonical IDs, anchors, coverage, and safe problem fields embedded in sealed application views | Pure document/terminal/Markdown render values for root CLI/MCP adapters | +| `tracedecay-api` | generated domain schemas, IDs, cursor/anchor/coverage and error primitives | Public wire-contract artifacts consumed by official clients | + +No consumer may duplicate enum spellings or legal predicate matrices.

Convergence boundary + +This crate is the only V2 physical persistence owner inside [`19-system-defragmentation-convergence-and-extensibility.md`](19-system-defragmentation-convergence-and-extensibility.md). It implements domain contracts from [`01-domain-crate.md`](01-domain-crate.md), scope candidate/storage semantics from [`16-cross-project-repository-worktree-scope.md`](16-cross-project-repository-worktree-scope.md), the sanitized/protected split from [`18-secret-detection-redaction-and-private-data-safety.md`](18-secret-detection-redaction-and-private-data-safety.md), immutable layer revision/activation/acknowledgement repositories from [`20-configuration-control-plane.md`](20-configuration-control-plane.md), scout run/envelope/delivery repositories from [`22-incremental-context-scout-and-suggestion-envelopes.md`](22-incremental-context-scout-and-suggestion-envelopes.md), and occurrence/copy/summary-horizon/temporal-eval repositories from [`23-session-lcm-temporal-retrieval-and-evaluation.md`](23-session-lcm-temporal-retrieval-and-evaluation.md). It never resolves precedence, ranks results, or interprets policy/config meaning. + +| Boundary | Contract | +|---|---| +| Enters | Domain IDs/owners/eligible payloads, sanitized observations, canonical projection commits, registered read fragments, commands, manifests, and explicit frozen watermarks. | +| Exits | Durable allocation/append/projection/command/migration/repair receipts, catalog candidate inventories, read snapshots, graph/blob/quarantine refs, and shard/vector watermarks. | +| Upstream owners | Domain owns values; capture owns sanitization and observation construction; projectors own derived semantics; application owns scope resolution and workflows. | +| Downstream consumers | Capture/projector/query/application ports consume storage capabilities; no transport or UI opens SQLite or paths. | +| Extension seam | New bounded storage capability requires a domain registry entry, typed repository port, migration chain, fault/backup/restore tests, manifest fields, and application adapter; no ad hoc SQL in consumers. | +| Scale/concurrency | One cross-process writer lease per live shard, bounded fair queues, WAL snapshots, immutable graph generations, manifest publication, cancellation, and vector—not global—progress. | +| Migration/retirement | V1 opens read-only through import adapters; after per-domain parity/cutover receipts, V1 serving paths retire and remain bounded rollback evidence only. Duplicate stores remain conflict evidence, never silently selected. | + +Store errors describe physical failure only (`busy`, `disk_full`, `corrupt`, `permission_denied`, `missing_key`, `schema_incompatible`, `stale_lease`, `watermark_unavailable`). Application maps them to the canonical public problem vocabulary from Plans 09/17. Store never invents user remediation, rank evidence, or transport retry objects. + +## 4. SQLite and driver decision + +V2 uses the synchronous `rusqlite` API. During coexistence, the dependency is declared exactly as: + +```toml +rusqlite = { package = "libsql-rusqlite", version = "=0.9.30", features = ["backup", "blob", "functions", "limits", "trace", "uuid"] } +``` + +This choice shares the SQLite C runtime already linked by V1 `libsql = "0.9.30"`, avoiding two SQLite implementations in one binary. V2 code imports only `rusqlite::{Connection, Transaction, OpenFlags}` and cannot import `libsql`, its async connection, remote URLs, replicas, or sync APIs. A dependency lint and link-smoke test enforce the boundary. After V1 removal, changing the package provider requires a measured storage-driver ADR, on-disk compatibility/integrity proof, backup/restore drill, and performance parity; it is not part of the first V2 default. + +Required SQLite behavior: + +- Every newly created mutable shard fixes `page_size=4096` and `auto_vacuum=INCREMENTAL` before the first schema transaction; changing either later requires a replacement-shard migration, integrity/size benchmark, and manifest swap, never an in-place opportunistic `VACUUM`. +- `PRAGMA journal_mode=WAL`, `synchronous=FULL`, `foreign_keys=ON`, `trusted_schema=OFF`, `recursive_triggers=OFF`, `temp_store=MEMORY`, `busy_timeout=5000`, `wal_autocheckpoint=1000`, and bounded negative `cache_size` selected by shard class/file size. Every open reads back and validates the effective values; unsupported/downgraded values fail the writable open. +- Every live SQLite family that can be written or checkpointed by another process opens with `mmap_size=0` on writers and readers. This includes catalog/activity/project shards and every coexistence graph database; the connection factory reads back and rejects a nonzero effective value. Only a cryptographically sealed immutable generation opened with no WAL/SHM family and no possible peer writer may opt into bounded mapping after an explicit benchmark/manifest decision. This preserves merged #436's mixed-page/checkpoint safety invariant instead of treating writer-only disablement as sufficient. +- Read-only opens use `SQLITE_OPEN_READ_ONLY | SQLITE_OPEN_NO_MUTEX`, `query_only=ON`, and a deferred transaction only for the duration of one request page. +- The writer connection is owned by one thread and is never shared through a mutex. +- Every mutation uses `BEGIN IMMEDIATE`; retry uses bounded jittered backoff and never hides a timeout behind success. +- WAL checkpoints are passive during normal work and `TRUNCATE` only under backup/maintenance lease after proving no busy frames. +- WAL pressure triggers a passive checkpoint at 256 MiB and scheduler backpressure at 1 GiB; a busy checkpoint never escalates to truncate while readers exist. Disk reserve accounts for DB + WAL + replacement-generation + backup simultaneously. +- FTS5 is contentless/contentless-delete with an explicit owner-row mapping and only classified, index-eligible text. FTS tables never own canonical content, triggers, retention, or authorization; rebuild creates a new versioned index generation from a frozen owner watermark, catches up through outbox, verifies counts/qrels, then swaps a manifest. +- New large B-tree indexes are built in a replacement shard/generation after disk preflight, not with unbounded `CREATE INDEX` on the live writer. Small metadata indexes may use a maintenance lease only when the benchmark proves the writer pause below 250 ms. Every index declares its query owner, selectivity/corpus evidence, build bytes/time, rollback removal, and `EXPLAIN QUERY PLAN` fixture. +- `ANALYZE` runs after schema/backfill/index publication and after at least 25% row-count drift; `PRAGMA optimize` runs under a bounded maintenance budget. Plans persist the SQLite/statistics generation in receipts. `VACUUM` never runs on a live shard; `incremental_vacuum` reclaims bounded pages only under disk/latency budgets, while full compaction uses replacement-copy/verify/swap. +- Runtime federation never uses `ATTACH`: application/query opens independently authorized read snapshots and combines them above the store. `ATTACH` is allowed only in isolated migration/repair tooling under lifecycle lease, at most two `mode=ro&immutable=1` source databases plus one new destination, with explicit manifests and no cross-file transaction claim. + +Physical forecast gates at the reference corpus and 10× synthetic corpus are recorded before schema freeze: `catalog.db` ≤256 MiB/2 GiB; `activity.db` ≤8 GiB/80 GiB excluding protected blobs; one repository `project.db` ≤2 GiB/20 GiB; one mutable shard WAL ≤1 GiB; graph packs follow §13's measured 512 MiB–2 GiB candidates. A forecast over budget must partition by an existing privacy/ownership boundary or change the indexed representation; it cannot create branch/board/session databases or silently raise file-count/open-connection limits. + +## 5.

The normative publication snapshot is [master §2.6](../2026-07-09-tracedecay-brain-rewrite.md#26-current-master-accepted-changes) plus [plan 13](13-research-provenance-and-context-anchors.md). Identity-split visibility, path-plus-inode holder checks, canonical paths, remapped LCM edges, dual backups, untracked branch-graph preservation, divergent session variants, indexed consolidation lookup, lifecycle fencing, conflict-safe registry healing, read-only search, peer-safe graph checkpoints, and restart-safe applied-manifest retirement are required fixtures. Every implementation/import PR refreshes current master/open state and exact store/schema/protocol inventories before generating manifests. + +### Merged #425 split-store consolidation contract + +The accepted final head is `d3bb28b57bef6f7fa513ff4b0645ce5e31a97872`, merged as `de3d05dc8f7f75028d8721b7d65c487459c5f170`. Its final path-plus-file/inode holder identity, canonical macOS/Linux/Windows store paths, and remapped LCM-source-edge preservation are required parity inputs, not incidental implementation details. + +Consolidating two non-empty profile/store authorities is an offline, resumable migration workflow, never resolver self-healing or an ordinary configuration write. The store layer must: + +1. identify both complete SQLite families through canonical platform locators (including the canonical macOS application-support location, while retaining legacy paths only as aliases/evidence) and freeze immutable read snapshots without mutating either source; +2. refuse when open-holder discovery is unsupported/incomplete, acquire the lifecycle lease plus explicit write reservations for both authorities, and revalidate identities after reservation; +3. create and independently verify one backup for each input before staging any merged destination; +4. recompute a deterministic confirmation digest from the frozen manifests, selected destination, schema/disposition plan, reservations, and backup receipts while the reservations are held; +5. append a restartable consolidation ledger before each staged copy/rebuild/verify/cutover transition, with idempotent row/payload mappings and no `INSERT OR REPLACE` loss; +6. verify exhaustive table counts, canonical identities and remap ledgers, sessions/messages/LCM payloads, every LCM summary/source edge after ID remapping, facts/feedback, branches/dirty sentinels, forensic artifacts, foreign keys, integrity, and source-to-destination disposition hashes; an edge whose source was remapped must point to the mapped source, never the legacy ID or nothing; +7. publish the destination/route cutover only after every required verification proof succeeds, then retain both frozen inputs and backups through the rollback window. + +Cancellation, crash, failed verification, lost reservation, or changed confirmation inputs leaves the prior routing authority intact. Recovery resumes from the durable ledger/staging manifest or removes only unreferenced staging artifacts. No step deletes, truncates, rewrites, or silently chooses between the two inputs. + +### Merged #438 applied-manifest retirement contract + +Merged #438 establishes the accepted restart-safe ownership rule: after consolidation has a verified canonical destination, an exclusive lifecycle owner revalidates the exact schema-2 source/target manifest pair, registry generation, aliases, file identities, and destination proof in one fenced operation. Only a manifest classified as a proven legacy `Applied` owner can transition to an immutable retired record; the original database/payload family remains untouched evidence. Transactional registry/manifest publication makes retries converge after crashes, and a disagreement, unsupported schema, active holder, lost lease, alias conflict, or changed destination leaves routing unchanged with a typed doctor finding. No normal resolver, search read, hook startup, or curation loop may perform this healing. + +## 6.

callers do not receive `Connection`, `Transaction`, SQL, or path access. `StoreReadRequest` accepts only registry-known read models, fields, predicates, and sort keys and caps `limit` at 1,000; the application-owned query/store adapter lowers query fragments into this storage-neutral contract. `ProjectionRepository` is the only projection-control authority: lease acquisition/renewal/release, checkpoint read/initialization, dead-letter read/resolution, projector effects, and contiguous advancement all use the exact `ProjectionCheckpointKeyV1`. `apply_projection` and `resolve_dead_letter` compare the full lease epoch and checkpoint, then commit typed effects, append-only dead-letter mutations/resolution receipts, emitted outbox rows, and any legal contiguous checkpoint in one SQLite transaction; no dead-letter or retry side channel can claim progress. The application-owned projector/store adapter lowers projector effects into it. `CatalogRepository::scope_candidates` performs indexed catalog lookup only and returns evidence-bearing candidates at one catalog generation; the application scope resolver owns normalization, authorization, scoring, ambiguity, current-default disclosure, relationship expansion, and the final `ScopeResolutionV2`. `ProtectedQuarantineRepository` is the sole exception to ordinary sanitized payload ingress: it accepts only the sanitizer-created, move-only `ProtectedQuarantineIngress` after an explicit detector/policy decision, encrypts into an unattached expiring staging object, and returns a move-only `ProtectedQuarantineAttachmentV1`. `ObservationJournal::append_transaction` consumes the token into a matching non-content skeleton and durable attachment intent; a post-commit reconciler advances the separate protected journal from `Staged` to `Attached`. Token/ref/observation uniqueness makes retry idempotent, and only a staged object with no committed intent can expire. General store/query ports cannot read plaintext, and Plan 18 owns key/TTL/audit behavior. + +Two registry/ownership clarifications: `RegisteredReadModelId` and numeric field IDs are issued by plan 04's read-model registry (one registry, versioned with the projector `builder_version`); the store validates read requests against the registered set pinned by projection checkpoints and never invents read-model or field IDs. And `ScopeCandidateInventoryV2.unmatched` shares one semantic with `ScopeResolutionV2.missing`: the application scope resolver maps `unmatched` roots into `missing` unchanged — no second coverage vocabulary exists between store and application. + +## 10. Concurrency, ordering, backpressure, and acknowledgement + +### 10.1 Writer topology + +- One `writer.lock` advisory lock permits one writer owner per live shard across processes. Lock release on process death makes takeover possible. +- The writer owner records a monotonic `lease_epoch` in `writer_leases`; every commit/ack includes the epoch. A stale writer cannot publish after takeover because the transaction compare-checks the epoch. +- Inside the owner process, one thread owns the SQLite writer connection. It drains a bounded `crossbeam_channel` of 4,096 batches and at most 64 MiB of accounted payload metadata. +- It groups up to 256 observations, 2 MiB of indexed metadata, or 5 milliseconds, whichever arrives first, while retaining FIFO order per source. It may interleave sources; it never claims cross-source causation. +- Hook producers never write to the store directly. Capture owns the one spool (`HookSpool`, plan 03): hook batches are always spooled under the capture-owned `activity/inbox//` lane first, and capture's drainer submits them through `Ingress`. Frame format (hash-chained CRC32 + SHA-256 frames), fsync discipline, backpressure thresholds, and spool receipts are plan 03 contracts; the store exposes only append transactions and no handoff-first fallback-spool protocol exists. +- `IngressAck::Committed` is returned only after SQLite commit; it is the only variant this crate ever constructs. The `DurablyQueued(SpoolReceipt)` variant is minted by capture's spool client (plan 03) when a batch is durably framed in capture's spool — never by the store. Queue overflow, disk-full, permission, or fsync failure returns an error; no event is dropped. +- Capture advances the canonical V2 source cursor only on `Committed`. A durably queued batch can be reread from the spool or source; deterministic IDs make drain replay a no-op. + +### 10.2 Atomic append + +One `BEGIN IMMEDIATE` transaction consumes one domain `ObservationAppendBatchV1` and performs: + +1. Rehash and schema-validate the complete replay manifest against `replay_manifest_digest`, compare the complete `expected_source_head`, validate registry/schema digest and writer lease epoch, and reject any mismatch without partial persistence. +2. For every `ObservationAppendItemV1`, validate its exact `ProvenanceV1` against the envelope's source/fingerprint/parser/ingested time, validate the receipt/quarantine relation, and, when present, validate the one-use protected token/ref/domain and insert the non-content skeleton plus attachment intent; then insert provenance, `SanitizationReceiptV1`, and observation with idempotent conflict checks. Provenance, receipt, envelope, skeleton, and intent can never commit separately; a protected ref/token cannot name two observations or cross privacy domains. The protected service remains `Staged` until the post-commit reconciliation in §10.2A. +3. Compare an existing ID's record and payload digests; mismatch is quarantined as `identity_collision` — a code from plan 03's versioned ten-code quarantine reason enum, which this crate consumes without minting local codes — and aborts canonical publication. +4. Classify source continuity against `source_heads`; insert/update `source_gaps` without deleting late evidence. +5. Derive one registry-authorized outbox intent per observation mutation from the envelope kind and append it with a shard-local sequence; callers cannot include canonical entities/events/relations, omit targets, or invent projector effects. Those canonical rows are written only by `ProjectionRepository` from registered projector output. +6. Publish the full `next_source_head` only across committed continuity rules; never jump over a gap or discard the schema-bound source cursor. +7. Commit, then send `AppendReceipt` containing lease epoch, per-observation disposition, first/last outbox sequence, committed timestamp, `ShardWatermark`, and the exact post-commit `SourceHeadV1`. Capture advances a provider cursor only from that returned head; `Gap`/`Late` evidence cannot fabricate advancement from the requested next head. + +Duplicates with identical digests return `Duplicate` and do not emit a second outbox record. A record below the contiguous head returns `Late`; it remains queryable by occurred and ingested time. A record above the expected offset returns `Gap` and does not move the contiguous head. Arrival of missing ranges closes/shortens gaps and advances the head deterministically. A higher rewrite generation starts a new source sequence; a conflicting digest at the same position without a higher generation is quarantined. + +### 10.2A Protected attachment recovery saga + +The protected object and canonical skeleton deliberately live in different failure domains, so no plan claims a cross-database atomic commit. `stage` first writes/fsyncs encrypted bytes, then appends `Staged` metadata in the privacy-domain quarantine journal and issues an HMAC-bound one-use token over `(protected_ref, privacy_domain, key_epoch, expires_at, receipt_id, manifest_digest)`. The owner-shard append transaction verifies that token and writes `quarantined_writes` plus `protected_attachment_intents`. After commit, reconciliation compares the exact intent and journal record and appends `Attached`; the token can never be reused. Recovery scans both directions: a committed intent with a `Staged` journal row is attached, an already attached pair is a no-op, and an unattached staged row with no committed intent is securely retired only after its TTL/grace horizon. Missing owner availability retains the encrypted object and emits a doctor finding rather than destroying evidence. + +Kill tests stop after encrypted rename, `Staged` journal fsync, owner transaction begin, skeleton insert, owner commit, protected `Attached` append, and secure retirement. Every restart converges to exactly one `(observation_id, protected_ref)` pair or one proven unreferenced retirement; no state exposes plaintext, loses a committed skeleton's object, advances a cursor before owner commit, or reports attachment from an uncommitted intent. + +### 10.3 Reads and vector watermarks + +- Each shard has a read-only pool capped at eight connections. A query opens at most 32 shards across the profile. +- A read page begins a deferred transaction, reads the shard outbox high watermark, applies `sequence <= captured watermark` predicates to mutable projections, reads rows, and closes the transaction before returning. +- The coordinator combines component watermarks into `VectorWatermark`; no read transaction remains open across pages. +- Frozen cursors resume at captured component watermarks. Live queries use delta positions, duplicate suppression by entity/event ID, and explicit gap/resync records. +- A missing/corrupt/incompatible shard contributes named partial coverage while other shard positions remain resumable. + +### 10.4 Outbox consumers and commands + +- Outbox consumption is at-least-once and idempotent by `(shard_id, sequence, projector_version)`. +- Consumer leases carry `consumer_id`, `lease_epoch`, `leased_until`, and batch ceiling. Checkpoint compares lease epoch and cannot skip an unprocessed sequence. +- Dead letters retain original sequence, error class, attempt count, next retry, and payload digest. They block “caught up” status until resolved or explicitly quarantined. +- Outbox lag reports sequence distance and oldest unconsumed commit age. Cutover requires p95 projection visibility at most two seconds for 24 hours and zero unexplained dead letters. +- Writable commands persist `CommandEnvelopeV1`, compare `expected_version`, write mutation/audit/outbox in one transaction, and cache result by idempotency key. Version conflicts return current version with no mutation. + +## 11. Schema and migration ownership + +Each database has `store_meta(store_kind, shard_id, profile_id, privacy_domain_id, schema_version, registry_version, registry_digest, created_at, migrated_at)` and `schema_migrations(version, name, sql_digest, started_at, committed_at, binary_version)`. SQL files are immutable after release. A changed digest is corruption, not a rerunnable migration. + +`tracedecay-domain::SchemaRegistryV1` and `PredicateRegistryV1` own semantic legality. `tracedecay-store` owns physical tables/indexes/triggers and persists the registry version/digest in every shard. Open behavior: + +- Equal schema and registry: open normally. +- Older compatible schema: writable open requires maintenance lease, disk preflight, backup, forward migration, integrity check, and receipt. +- Newer schema/registry: refuse writes and expose incompatible read-only coverage. +- Registry digest mismatch at the same version: quarantine the shard and refuse semantic reads. + +This section is the sole physical-schema authority for V2. Where the master plan's §8 illustrative schemas differ, this plan supersedes them; specifically: master's `edges(edge_id, src_id, dst_id, kind, attrs)` is this plan's `relation_assertions`; master's `activity_scope_assertions` table is expressed as registered attribution relation assertions, not a dedicated table; master's `reasoning_summaries` is `reasoning_artifacts`; master's `work_claim_events` is `coordination_events`; master's single `search_documents` is the per-shard `activity_search_documents`/`project_search_documents`; master's inline event `attrs` column is the blob-plus-`event_attr_index` shape below; master's `outbox(owner, event_id, projector_targets, created_at)` is this plan's outbox shape; `identity_allocations` keeps `owning_shard_id`; `entity_versions` keeps `supersedes_version_id`; and master §7.5's blob path prose defers to the Section 8 layout (`privacy//blobs///…`).

This is how every `*_blob_id` column decomposes a full domain `PayloadRef`: the column stores the `BlobId`, the same transaction commits the matching `blob_refs` row carrying the remaining fields (domain, integrity tag, length, media type, schema, sensitivity, receipt), and readers reconstruct the exact `PayloadRef` from that row — no eight-column copy per referencing table. +- `consumer_leases(projector BLOB, projector_version BLOB, shard_id BLOB, generation BLOB, lease_id BLOB NOT NULL UNIQUE, owner_instance_id BLOB NOT NULL, lease_epoch INTEGER NOT NULL, leased_until INTEGER NOT NULL, batch_ceiling INTEGER NOT NULL, PRIMARY KEY(projector, projector_version, shard_id, generation))`; the primary key is exactly `ProjectionCheckpointKeyV1`. `projection_checkpoints(projector, projector_version, shard_id, generation, contiguous_sequence, highest_seen_sequence, source_watermarks_blob_id, schema_registry_version, builder_version, status, updated_at, PRIMARY KEY(projector, projector_version, shard_id, generation))` losslessly lowers plan 01's `ProjectionCheckpointV1`.

Creation/attempt/resolution and any legal projector effects are `DeadLetterMutationV1` members of one projection transaction. A blocking record prevents checkpoint advancement; resolution cannot independently move the checkpoint, and compaction requires a terminal resolution plus the evidence-retention watermark. +- `command_results(idempotency_key BLOB PRIMARY KEY, command_id, aggregate_version, result_digest, committed_at)` with `ResponseCache` retention (7 days); `retention_holds(hold_id PRIMARY KEY, owner, scope, reason, issuer, created_at, expires_at, version)`. +- `retrieval_anchor_records(anchor_id PRIMARY KEY, target_kind, target_ref, resolved_scope_id, privacy_domain_id, access_policy_digest, source_identity_class, immutable_source_refs_blob_id, source_observations_blob_id, vector_watermark_blob_id, schema_registry_digest, capability_catalog_digest, data_version_digest, projection_version, view_algorithm_version, retrieval_view, expansion_recipe_blob_id, canonical_request_digest, provenance_blob_id, payload_access, retention_class, created_at, durability, tombstoned_at)` in the owning activity/project shard. Every blob field uses the record's privacy domain and a sink-eligible typed schema. + +Anchor creation commits owner-shard `retrieval_anchor_records`, catalog `retrieval_anchor_routes`, and outbox intent through a resumable application workflow; an unrouteable half-created anchor is not returned. Startup/repair reconciles the saga's orphans: an owner record without a catalog route re-emits the route from the committed outbox intent; a route without an owner record is tombstoned with a repair receipt after the 24-hour grace — neither state survives silently. Resolution authorizes the content-free route, pins the owner snapshot, then loads exactly one record. Retention replaces the owner record with a typed tombstone state and updates the route; it never reuses the ID or redirects to a similar entity. Backup/restore, key rotation, adoption/move, and shard reconciliation verify anchor route/record counts and digests. + +Activity/profile canonical tables: `actors`, `agent_instances`, `agent_presences`, `work_claims`, `work_claim_scope_entities`, `work_claim_retrieval_anchors`, `coordination_events`, `threads`, `thread_sessions`, `sessions`, `workflow_runs`, `turns`, `messages`, `content_parts`, `message_occurrences`, `message_origin_assertions`, `logical_message_clusters`/`logical_message_cluster_members` (superseding the earlier `message_representative_memberships` name — representative membership is cluster membership, Section 11.4), `message_copy_assertions`, `reasoning_artifacts`, `tool_invocations`, `tool_results`, `approvals`, `goals`, the complete plan-24 task-graph family fixed in Section 11.3A (`initiatives` through `task_view_shares`; no monolithic `tasks`, board database, `context_packets`, or `task_events` alias exists), `installations`, profile-scoped `skill_materializations`, `doctor_findings`, `remediation_events`, fact/skill/policy/automation histories, `hint_state_snapshots`, `hint_outcome_records`, `lifecycle_leases`, `drain_receipts`, `checkpoint_receipts`, `service_state_events`, encrypted saved-view/annotation content, and `activity_search_documents`. Task migrations land under this crate's `src/migrations/sql/activity/`; plan 24 lists the semantic family but does not own another migrations directory. `threads` preserves provider-native conversation/thread identity independently of execution/session identity; `thread_sessions` is temporal, evidence-bearing, and many-to-many. Presence/work claims are canonical activity because an agent can span zero/many projects; project shards receive safe claim locators. TTL status uses immutable heartbeat/expiry events and never deletes history. Project attribution is relation evidence. Message-origin and representative rows never delete or overwrite a native message row. + +Coordination indexes cover `(status, expires_at)`, agent/session/parent/goal, each canonical scope entity kind, intent, redundancy mode, and retrieval-anchor digest. Safe summaries are activity payload fields, never catalog/metric/project-locator text. Expiry is an indexed current-view predicate plus explicit event, not a cleanup race. Coordination growth is bounded by retention class: heartbeat/expiry `coordination_events` carry `RawTelemetry` (180 days) and roll up into per-claim outcome receipts before aging out, while claim lifecycle events (declared, acknowledged, handed off, completed, cancelled) are `NormalContent` — TTL still controls only current visibility, never historical deletion inside the horizon. + +Project-only canonical/history tables: `repositories`, `projects`, `checkouts`, `worktrees`, `refs`, `commits`, `pull_requests`, `checks`, `reviews`, `releases`, `activity_locators`, plus project-scoped `facts`, `fact_versions`, `knowledge_entities`, `decisions`, `contradictions`, `trust_events`, `retrieval_events`, `feedback_events`, `policy_bundles`, `policy_evaluations`, `hint_evaluations`, `automation_jobs`, `scheduler_decisions`, `automation_runs`, `run_events`, `automation_artifacts`, `skill_versions`, `skill_materializations`, `doctor_findings`, `remediation_events`, `curation_candidate_versions`, `autonomy_decisions`, `autonomous_effect_events`, `outcome_events`, `automatic_recovery_events`, imported `legacy_approval_events`, `project_search_documents`, and rollups. The same typed histories may be owned by activity when their declared scope is profile/zero-project/cross-project or unresolved. Current views are projections over immutable histories; no V2 approval queue table exists. + +### 11.3 High-volume canonical table shapes + +These are the largest migration surfaces (388k+ messages, 59k+ hook-observed tool calls at the reference corpus); their column shapes are fixed here, not deferred.

Unknown nonpreemptible effects remain `Quarantined` and retain blocking keys until reconciliation; expiry alone never proves external work stopped. +- `imported_execution_observations(imported_observation_id BLOB PRIMARY KEY, source_manifest_id BLOB NOT NULL, native_run_id_keyed_digest BLOB NOT NULL, work_item_id BLOB NOT NULL, observed_ordinal INTEGER NOT NULL, observed_status TEXT NOT NULL, started_at INTEGER NULL, ended_at INTEGER NULL, requested_route_evidence_blob_id BLOB NULL, workspace_locators_blob_id BLOB NULL, artifacts_blob_id BLOB NULL, sanitization_receipt_id BLOB NOT NULL, missing_fields_blob_id BLOB NOT NULL, ingested_at INTEGER NOT NULL, UNIQUE(source_manifest_id, native_run_id_keyed_digest))`; indexes `(work_item_id, observed_ordinal)`, `(observed_status, ingested_at)`.

Identity allocation and repository ownership + +- Exact source/native IDs derive in `tracedecay-domain`; the store verifies derivation before insert. +- Canonical alias history and literal values remain authorized evidence in their activity/project owner shard. A projector publishes versioned exact/token/ngram keyed digests plus owner/provenance/tombstone state to the content-free catalog routing index. Application computes comparable digests only after selecting an authorized privacy domain/key epoch, uses the catalog to prune candidate shards, then verifies current literal/evidence state in each selected owner shard before resolution. Key rotation rebuilds the routing generation atomically; stale generations return unavailable coverage and never fall back to unkeyed or all-shard scanning. +- `resolve_or_allocate` runs `INSERT ... ON CONFLICT(allocation_key) DO NOTHING`, reads the row in the same transaction, and verifies kind/owner/source manifest. New IDs are UUIDv7 from an injected generator and committed before publication. +- Profile/global allocation rows live in catalog; activity-native and profile-scoped knowledge/policy/automation ambiguous rows live in activity; repository/project/code and project-scoped knowledge/policy/automation ambiguous rows live in project. +- Backups and restores include every allocation table before any projector rebuild. Missing allocation ledgers stop restore; no replacement UUID is minted. +- Repositories, checkouts, worktrees, and monorepo subprojects are views/entities inside one canonical repository/privacy-domain project shard. Branches and worktrees cannot own facts, skills, or canonical activity. +- PR #405 adoption evidence is evaluated before allocation. One unique healthy legacy store can retain lineage; multiple healthy/nonempty candidates remain distinct and create an identity conflict relation plus import blocker. +- PR #407 does not create a Hermes profile. Hermes sessions become activity entities. Facts, skills, policy, and automation resolve by `DeclaredScope`: profile/zero-project/cross-project and unresolved-scope histories live in activity; explicitly project-scoped histories live in the canonical repository project shard. Scope resolution and later supersession remain evidence. + +## 13. Graph generation store + +`GraphGenerationRepository` exposes: + +```rust +pub trait GraphGenerationRepository: Send + Sync { + fn begin_generation(&self, request: GenerationRequest) -> Result; + fn publish_generation(&self, sealed: SealedGeneration) -> Result; + fn open_resolved_snapshot( + &self, + resolved: &ScopeResolutionCandidateV2, + ) -> Result; + fn compact(&self, request: CompactionRequest) -> Result; +} +``` + +Generation DBs contain deduplicated file content, file/symbol occurrences, snapshot-scoped code edges, diagnostics, tests/test maps, fingerprints, redundancy, complexity, and rebuildable FTS/vector metadata. Manifests map every `CodeSnapshotId` to its repository, checkout, zero-to-many worktree/ref locators, generation plus overlay chain, checksum, extractor/resolver versions, and source watermark. `open_resolved_snapshot` verifies every nonempty tuple field and freshness watermark against that manifest; mismatch returns typed stale/ambiguous coverage and never opens the active/base/current generation instead. Refs are movable locators, snapshots/generations are immutable, and multiple refs may name the same snapshot. Generation contents and build plans are produced by plan 25's `tracedecay-code-index` indexing pipeline; this crate owns only physical staging, verification, publication, compaction, and manifest state. + +Publication sequence: build under `staging`, run `quick_check` and row/hash manifest verification, fsync DB and directory, rename to final generation path, then compare-and-swap the project graph manifest under project writer transaction. Startup removes incomplete staging files, quarantines checksum failures, and registers final-but-unreferenced files as orphans for grace-period cleanup. + +The storage ADR benchmark runs candidates of 32/64/128 snapshots per pack and 512 MiB/1 GiB/2 GiB target pack sizes at current and 10× corpora. It selects the smallest candidate meeting query/compaction/file-count gates and records it before constants are committed. Overlay depth candidates are 2/4/8; the selected value must keep snapshot-open p95 within gate and profile graph files below 10,000 after compaction. At most eight generation files are open per query process. + +## 14. Privacy-domain blob store + +Blob identity is exact: + +1. Require `SanitizedPayload` plus its domain `SanitizationReceiptV1` before `BlobWriteRequest`; the store never classifies, scans, redacts, or mints the proof. +2. Compute an internal `ContentDigest = SHA-256(canonical uncompressed bytes)` for verification. It never enters catalog rows, public payload references, logs, or cross-domain APIs; protected mode stores it only inside the encrypted blob header. +3. Compute `BlobId = HMAC-SHA-256(K_domain_dedupe, key_epoch || retention_class || content_digest)` and a separately keyed opaque `BlobIntegrityTag` for the public/domain reference. +4. Compress eligible normal content with zstd before encryption; record compression and original/stored sizes. +5. In protected mode encrypt with XChaCha20-Poly1305 using a random nonce and per-domain encryption key supplied by `BlobKeyProvider`; keys never enter SQLite or manifests. +6. Exclusive-create a private staged file, write header+ciphertext, fsync, reread/verify header/hash/size, rename atomically to final path, fsync parent, then publish metadata/ref/outbox in the owning shard transaction. + +Because privacy domain, key epoch, and retention class enter the keyed ID/domain path, equality and lifetime do not leak across those boundaries. Refcounts are advisory. GC mark-and-sweeps from signed shard/backup manifests, committed owner refs, protected holds, and committed outboxes. The sweep's consistency point is explicit: a sweep pins one vector watermark at mark start, and immediately before each unlink it re-reads that shard's committed `blob_refs`/outbox ref-publications above the pinned component — so a ref committed mid-sweep is excluded by re-scan, not merely by luck; the 24-hour grace then covers the residual window between re-scan and unlink. Unreferenced final files wait 24 hours in recovery grace; missing referenced files quarantine the ref and make coverage partial. Key rotation creates a new epoch and rewrap/re-encrypt job; destructive retirement requires a verified encrypted recovery export. + +## 15. Retention, deletion, and holds + +- Eligibility uses domain `RetentionPolicyV1`: required `ingested_at < evaluated_at - horizon`; exact-cutoff content remains. Normal content is indefinite, reasoning 30 days, secret quarantine 24 hours, response cache 7 days, raw telemetry 180 days, automation intermediates 90 days. +- A retention worker holds one fenced lease per privacy domain and operates in bounded batches of 1,000 owners or 64 MiB. +- Preview resolves descendant entities/projections/blob refs, holds, expected bytes, and the exact vector watermark. +- Apply transaction writes canonical tombstone/deletion receipt, removes FTS/vector/search rows, releases blob refs, emits outbox, and advances retention watermark. Physical blob GC occurs after 24-hour recovery grace. +- Pinned/legal holds name owner, scope, reason, issuer, creation/expiry, and optimistic version. Expired holds remain audit events. +- Canonical tombstone and FTS/vector removal must complete within one minute of approved deletion. Non-content provenance skeleton and deletion receipt persist. +- Queries/cursors whose evidence crossed the captured retention watermark receive `RetentionCrossedSnapshot` and a restart/incompleteness reason. + +## 16. Backup, integrity, crash recovery, and repair + +- A backup lease freezes migrations/retention/graph manifest swaps, records a vector watermark, and uses SQLite online backup API per mutable shard. Live ingest may continue above the captured component watermark. +- Backup manifest includes schema/registry versions, shard and identity-allocation digests, SQLite page counts/hashes, graph manifests, blob inventory, outbox high watermarks, source heads/gaps, privacy/key epochs, redaction report, and coverage. +- Restore verifies all hashes, restores allocation ledgers first, opens databases read-only, checks `quick_check`, registry digest, foreign keys, outbox/checkpoint bounds, graph manifests, and blob refs, then runs plan 18 §12.4's isolated-staging gate — the restored set is privacy-migrated and scanned in staging under current detector/policy versions and a promotion receipt is recorded — before publishing a new catalog manifest. A restore that skips the staging scan cannot promote. +- Catalog rebuild reads signed shard/graph/blob manifests and committed outboxes. It never reconstructs content or missing allocation IDs. +- Startup recovery replays capture-spool drain batches idempotently (deterministic observation IDs make re-appended batches no-ops; the spool itself is capture-owned), removes incomplete stages, completes or reverts migration receipts, verifies lease epochs, detects outbox/checkpoint gaps, and quarantines corrupt shards without blocking healthy shards. +- Repair is split into operation-specific `repair.inspect` and confirmed resumable `repair.start` use cases with idempotency, optimistic version, lifecycle fencing, and receipts; it never silently drops evidence or hides behind a generic preview/apply framework. +- Killpoints cover capture-drain batch submission (spool-frame fsync killpoints are plan 03's), observation insert, outbox insert, source-head update, commit-before-ack, blob rename, ref publish, graph rename, manifest swap, migration step, backup, retention tombstone, ref release, and GC unlink. + +## 17. Import, parity, and cutover + +Import sanitization ownership is split exactly once: capture (plan 03, PR 7E) owns V1 parsing and sanitization — every V1 payload passes the mandatory sanitizer and receives a capture-minted `SanitizationReceiptV1` — and `V1Importer` here is only the storage-side transaction executor for the sanitized batches capture hands it. The importer performs no parsing or classification (Section 2 non-goals hold during import), refuses any receiptless payload, and persists the receipts into `sanitization_receipts` (Section 11.2) alongside the imported rows; plan 12 references this split in its cutover sequencing. + +`V1Importer` opens all V1 SQLite databases read-only for inventory/counts and writes only V2 destinations. Each source gets a `ManifestId`, logical digest, schema version, table counts/hashes, source offset range, payload inventory, identity aliases, quarantine list, and import watermark. Re-running the same manifest produces no additional observations/entities/events/outbox records. + +Import order: + +1. Inventory V1 `src/storage.rs` manifests, global registry, project aliases, branch metadata, graph DBs, sessions/LCM DB, payload/response/artifact roots, automation files, and retention configuration. +2. Ingest PR #405 repository identity markers/candidate inventories/adoption receipts. Preserve every conflicting store and block repository cutover on ambiguity. +3. Ingest PR #407 Hermes migration ledgers/logical source fingerprints, including facts-only stores and moved/renamed/symlinked project resolution evidence. Do not scan or route new canonical data to a Hermes-owned profile. +4. Import PR #410 native rows and expected origin/representative query outcomes as parity evidence; do not rewrite or drop copied rows. +5. Import catalog/global identity evidence and persist allocation mappings. +6. Import canonical activity observations/sessions/messages/turns/reasoning/tools/goals/workflows and LCM source/DAG lineage — consuming capture PR 7E's sanitized, receipt-bearing batches; the executor rejects any batch lacking receipts. +7. Import project Git/delivery, knowledge/facts/trust/feedback, skills/curation/automation histories, and activity locators. +8. Import graph snapshot generations and payload blobs. +9. Compare counts, hashes, aliases, ordinals, timestamps, source offsets, summary coverage, native/representative/origin counts, fact versions, skill/proposal versions/outcomes, and quarantine. Emit a signed parity receipt. + +V1 remains authoritative until the bounded context's freeze watermark. Cutover requires dual capture success, zero unexplained parity gaps, no identity conflict, no dead letter, p95 visibility at most two seconds for 24 hours, backup/restore proof, and rollback drill. V1 stores remain read-only for one release after verified cutover. Rollback restores V1 source-offset ownership from the receipt, stops V2 writer leases, retains V2 read-only evidence, and does not reverse-delete V2 files. + +## 18.

The store rehashes the manifest, validates provenance against envelope/source/fingerprint/parser/time, compare-and-sets the full expected source head, inserts provenance plus receipt plus envelope plus quarantine skeleton, derives one registry-authorized outbox intent per new observation, and advances the head in one transaction. `AppendReceipt.post_commit_source_head` is the sole acknowledged cursor authority: `Gap`/`Late` can commit evidence without advancing it. A crash before commit leaves the previous head; a crash after commit returns the existing receipt on retry. + +`ObservationSanitizer` is the only implementation permitted to construct `SanitizedObservation` or mint `SanitizationReceiptV1`. For a protected candidate, `CaptureRunner` moves its non-cloneable `ProtectedQuarantineIngress` through `ObservationSink::stage_protected`, then moves the returned private attachment token into `ObservationQuarantineDispositionV1`; ordinary observations require no staging. It moves every envelope/receipt/disposition intact into `ObservationAppendItemV1`. Capture mints every receipt; the durable receipt home is the per-shard `sanitization_receipts` table defined in [`02-store-crate.md`](02-store-crate.md), and `ObservationSink::commit` persists each receipt in the same transaction as its envelope. Plan [`04-projectors-crate.md`](04-projectors-crate.md)'s sink firewall validates receipts against that table; [`18-secret-detection-redaction-and-private-data-safety.md`](18-secret-detection-redaction-and-private-data-safety.md) defines the receipt's fields and invariants. Adapters parse and identify structured fields but cannot classify eligibility themselves. `ObservationSink` rejects an envelope whose receipt, output digest, privacy domain, parser/detector/policy digest, completeness, or protected attachment token does not match. Incomplete/timeout/unsupported scans become receipt-bearing non-content items inside the same append batch; only unattached encrypted staging can remain after failure, and the protected service retires it without advancing the source head. + +### Deterministic identity, rewrite, offsets, and ordering + +```rust +pub struct CaptureObservationIdentity { + pub source_instance: SourceInstanceId, + pub artifact_id: ArtifactId, + pub generation: RewriteGeneration, + pub position: SourcePosition, +} + +pub fn lower_observation_key(input: &CaptureObservationIdentity) -> tracedecay_domain::ObservationKey; +pub fn detect_rewrite( + committed: Option<&SourceHeadV1>, + artifact: &SourceArtifact, +) -> RewriteDecision; +``` + +`SourceRecord.bytes` and any transient checksum exist only in bounded capture/sanitizer memory and cannot implement `Serialize`, `Display`, logging, repository, or receipt traits. The sanitizer computes `KeyedSourceRecordFingerprint` with the privacy-domain key after parsing/classification. The fingerprint enters envelope/provenance/source-head verification fields, never `CaptureObservationIdentity` or `ObservationKey`; observation identity remains stable across key rotation. + +- `SourceInstanceId` is a namespaced deterministic ID over profile, host installation, adapter ID, and provider-native source instance. +- `ArtifactId` is a namespaced deterministic ID over source instance plus the provider-native durable artifact identity; a pathname is only one alias. +- The adapter normalizes the four `CaptureObservationIdentity` fields into the domain `ObservationKey` canonical field encoding; `derive_observation_id` is the only observation-ID implementation. Capture may not define a second UUID namespace or canonical encoder. +- `SourcePosition` persists through the offset-lowering columns defined in [`02-store-crate.md`](02-store-crate.md): `observations` stores `(position_kind TEXT, byte_start INTEGER NULL, byte_end INTEGER NULL, object_key_digest BLOB NULL)` with `source_heads.contiguous_offset` retained only for byte/row/sequence ordered sources. Capture treats the lowering as opaque and round-trips every variant, including keyed `ObjectKey(PrivacyDomainBoundLocatorDigest)` and `ByteOffset{start,end}`. +- Key rotation never changes an `ObservationId`. Under the lifecycle lease, the sanitizer/key service can recompute active-source fingerprints with old and new epochs while authorized source bytes are transiently available, append a signed `FingerprintEpochContinuityV1` receipt, and advance only the verification fingerprint/head epoch. If continuity cannot be proven, capture starts a named rewrite generation or quarantines; it never compares raw digests, silently treats an epoch mismatch as a rewrite, or duplicates the prior generation. +- Append growth with matching artifact and head fingerprints preserves the generation and resumes at the committed cursor. +- Truncation, head-fingerprint change before the committed offset, SQLite replacement, or native artifact identity change starts `generation + 1`; old observations remain immutable. +- The final unterminated JSONL line is not acknowledged. Malformed complete records are quarantined and the cursor advances only when the quarantine skeleton and outbox marker commit atomically. +- Duplicates preserve one canonical observation plus duplicate-seen metrics. Late/out-of-order records retain occurred time, ingested time, source position, and `late_by`; capture never rewrites prior order. +- A per-source sequence gap emits `capture.sequence_gap_detected`; later arrival emits `capture.sequence_gap_filled`. The drainer waits only for the configured bounded reorder window and never invents missing records. + +### Hook hot path and concurrent-agent contract + +```rust +pub struct RawHookObservationDraft { + pub producer: HookProducerId, + pub provider: ProviderId, + pub host: HostInstanceId, + pub session_hint: Option, + pub agent_hint: Option, + pub parent_agent_hint: Option, + pub correlation_hint: Option, + pub event: Unclassified, + pub occurred_at: UtcMicros, +} + +pub struct WorkClaimScopeDraft { + pub repositories: Vec, + pub worktrees: Vec, + pub refs: Vec, + pub pull_requests: Vec, + pub files: Vec, + pub symbols: Vec, + pub query_scope: Option, +} + +pub struct WorkClaimDraft { + pub native_claim_id: Option, + pub goal_hint: Option, + pub scope: WorkClaimScopeDraft, + pub intent: WorkIntent, + // Pre-sanitizer candidate text; only the sanitizer validates it into + // `SafeCoordinationSummary` after scanning. + pub summary: Option, + pub retrieval_anchors: Vec, + pub redundancy: RedundancyMode, + pub status: WorkClaimStatus, + pub expires_at: UtcMicros, +} + +pub enum HookEventV1 { + SessionStarted, + PromptSubmitted { content: ProviderFieldValue }, + AgentSpawned { child: NativeAgentId, task: ProviderFieldValue }, + AgentMessage { recipient: NativeAgentId, content: ProviderFieldValue }, + AgentHandoff { recipient: NativeAgentId, state: ProviderFieldValue }, + AgentPresenceHeartbeat { status: PresenceStatus }, + WorkClaimDeclared { claim: WorkClaimDraft }, + WorkClaimScopeChanged { claim_id: String, scope: WorkClaimScopeDraft }, + WorkClaimAcknowledged { claim_id: String, redundancy: RedundancyMode }, + CoordinationOutcomeObserved { claim_id: String, outcome: CoordinationOutcome }, + ToolStarted { call_id: String, tool: String, input: ProviderFieldValue }, + ToolFinished { call_id: String, outcome: ToolOutcome, output: ProviderFieldValue }, + CompactStarted, + CompactFinished, + HintTerminal { hint_id: String, terminal: HintTerminalState }, + SessionStopped { outcome: Option }, +} + +pub struct HookSpool; + +impl HookSpool { + pub fn append( + &self, + observation: &SanitizedHookObservation, + deadline: std::time::Instant, + ) -> Result; + pub fn acknowledge(&self, ack: HookAck) -> Result<(), HookSpoolError>; + pub fn recover(&self) -> Result; +} +``` + +Capture owns the one hook spool and its drainer. There is exactly one spool implementation, one hash-chained frame format (below), and one always-spool ingress protocol; the store exposes only append transactions and never runs a handoff-first or fallback ingress spool of its own ([`02-store-crate.md`](02-store-crate.md) drains capture's spool through `ObservationJournal` appends). Plan [`07-hooks-crate.md`](07-hooks-crate.md) hook hosts write exclusively through capture's spool client (`spool/client.rs`) and receive durability acks carrying the domain `SpoolReceipt` from [`01-domain-crate.md`](01-domain-crate.md); no crate mints a spool-receipt variant. + +`RawHookObservationDraft` exists only in adapter memory. Plan 07's wire shape `Unclassified` decodes one-to-one into `RawHookObservationDraft` at the capture client boundary; no second pre-sanitizer hook shape exists. The hook adapter parses and sanitizes it through the same `ObservationSanitizer` before constructing `SanitizedHookObservation`; only that sanitized wrapper can serialize into a spool frame. A scanner timeout or unavailable privacy policy fails closed with no content retention: it produces a non-content receipt and no hint/content frame, and no encrypted or deferred-scan copy of the input is spooled anywhere outside the store's isolated protected-quarantine service. This fail-closed no-content-retention rule is the canonical statement for the plan set; Plan 18's hook target restates it. It is the mandatory-security tradeoff defined by Plan 18, not a provider-specific fast-path bypass. + +- The producer lane is `(profile, host, provider, native session, native agent, process nonce)`. One locked lane allocator assigns a monotonic `sequence`; unrelated agents never share a lock. +- Each append writes a length-delimited frame with version, producer, sequence, payload length, CRC32, SHA-256, and previous-frame hash to a private segment, then calls `fdatasync` before returning the domain `SpoolReceipt`; a successful receipt is the `Durable` ack. +- The 10 ms deadline bounds synchronous lock/flush time. Contention rotates to a unique pending segment via atomic create; it does not wait on the main lane. Disk-full/permission failures return `HookSpoolError::Unavailable` to the hook adapter and emit a visible stderr/host diagnostic; they are never reported as captured. +- Backpressure thresholds are 64 MiB per producer and 2 GiB per profile by default. Crossing the soft threshold still appends durably but flags `DeferredBackpressure` on the receipt and wakes the drainer; crossing the hard threshold rejects content-bearing frames but reserves a 1 MiB metadata lane for one `capture.spool_overflow` marker per producer/hour. +- The drainer verifies the hash chain and CRC, merges lanes by `(occurred_at, producer, sequence)` only for display, commits each producer sequence independently, and writes contiguous acks only after the observation/outbox commit. +- Ack durability uses the store's spool-acknowledgement port with one row shape, `SpoolAckRecordV1 { producer_lane: ProducerLaneId, segment_id: SpoolSegmentId, contiguous_sequence: u64, drainer_lease_epoch: u64, acked_at: UtcMicros }`: primary key `(producer_lane, segment_id)`, compare-and-set on `drainer_lease_epoch`, index on `acked_at` for grace-period compaction, owned by the profile activity shard, and retained only until its segment is deleted after the 24-hour grace. +- Segment deletion requires every sequence in the segment to be durably acknowledged plus a 24-hour recovery grace. Multiple drainers use leases and compare-and-set acks; duplicate reads are harmless. +- Parent/child, inter-agent, tool, goal, and hint relationships remain hints in observations.

Capture never infers material overlap, cancels work, or copies raw task/prompt text into the summary. +- File/Git/memory links retain exact tool/event/source references so projectors can cross-link Turn graphs to timeline, code snapshots, worktrees/commits/PRs, facts/retrieval, and automation without temporal guessing. + +### Privacy, reasoning, quarantine, and replay + +```rust +pub enum ReasoningArtifactFormat { + Summary, + AnalysisText, + Structured, + Encrypted, + Unavailable, +} + +pub struct ReasoningArtifactDraft { + pub format: ReasoningArtifactFormat, + pub visibility: ProviderVisibility, + pub content: Option, + pub provider_digest: Option, + pub unavailable_reason: Option, +} + +pub struct CaptureReplayManifestV1 { + pub mode: tracedecay_domain::ReplayMode, + pub source_artifacts: Vec, + pub observation_ids: Vec, + pub parser_artifact_digest: ManifestDigest, + pub parser_config_digest: ManifestDigest, + pub privacy_policy_digest: PrivacyPolicyDigest, + pub detector_set_digest: DetectorSetDigest, + pub sanitization_receipts_digest: ManifestDigest, + pub provider_schema_versions: Vec, + pub evaluator_bundle_digest: Option, + pub index_watermarks: Vec, + pub memory_manifest_digest: Option, + pub tool_catalog: Option, + pub substitutions: Vec, + pub unavailable_inputs: Vec, +} +``` + +- `Summary`, `AnalysisText`, and `Structured` content is accepted only when the provider delivered it to the host/user. `Encrypted` records store provider metadata/digest and no decrypted text. `Unavailable` is an explicit coverage marker. +- Reasoning defaults to 30-day retention and is excluded from FTS, vectors, facts, shares, and exports. Capture sets policy metadata; downstream stores enforce it. +- Secret-like content is sanitized before the envelope. When explicit policy permits forensic inspection, the store's separate protected-quarantine service first stages encrypted transient bytes under a random `ProtectedSecretRef` with a 24-hour expiry and one-use attachment token. The observation envelope itself carries only a safe marker/receipt, broad reason class, and coverage—never spans, length, prefix/suffix, or candidate digest. The append transaction consumes the attachment token into the non-content `quarantined_writes.protected_secret_ref` skeleton; retry is idempotent by ref/token. A crash or rejected append leaves only an unattached encrypted staging object, which the protected service securely retires after a short grace and never indexes or returns through general reads.

Temporal proximity yields no causal edge. + +### Outbox, checkpoints, watermarks, and concurrency + +```rust +use tracedecay_domain::{ProjectionCheckpointKeyV1, ProjectionCheckpointV1}; + +pub struct ProjectionCoordinator { + registry: R, + store: S, + config: CoordinatorConfig, +} + +impl ProjectionCoordinator { + pub fn run_once(&self, request: RunProjectionRequest) -> Result; + pub fn run_until(&self, target: VectorWatermark) -> Result; +} +``` + +`VectorWatermark` above is the domain type, not a projector-local copy. Coordination uses `partial_cmp_components`, `dominates`, and `merge_max`; incomparable vectors stay incomparable and no scalar/global ordering is introduced. + +Plan 01's `ProjectionCheckpointV1` is the single checkpoint shape in the system. It persists losslessly only in plan 02's `projection_checkpoints` table, keyed by `ProjectionCheckpointKeyV1`. Plan 02's one `ProjectionRepository` owns lease acquire/renew/release, checkpoint read/initialization, dead-letter read/resolution, and atomic projection application. Initialization requires an absent zero checkpoint; every later advance occurs only through `apply_projection` or an atomic replay resolution with the full expected checkpoint and exact lease epoch ([`02-store-crate.md`](02-store-crate.md)). No crate defines a reduced checkpoint/lease key, directly writes dead-letter state, or moves progress through a side channel. + +- One lease exists per `(projector, version, shard, generation)`. Different projectors/shards run concurrently; independent agent sources do not serialize. +- The worker obtains that exact-key lease through `ProjectionRepository::acquire_lease`, reads/initializes the exact checkpoint, renews before its TTL safety margin, and releases on a clean stop. Store CAS—not host liveness guesses—fences a stale worker. +- A leased worker reads a bounded batch after `last_contiguous_sequence`. Duplicate outbox rows are idempotent. Missing outbox sequence stops contiguous advancement and records `projector.outbox_gap`; the worker may process only explicitly commutative rows beyond the gap into a nonpublished staging generation. +- Source-sequenced activity preserves `(producer, sequence)`. Cross-agent display order uses occurred time, ingested time, producer, sequence, and event ID as a deterministic sort, but it does not assert causation. +- Parent/child, spawn, inter-agent message, handoff, tool-result, and goal-transition relations use provider/host IDs or direct event references. Unresolved targets remain candidate relations; later resolution supersedes the candidate. +- Batch size defaults to 1,000 events or 50 ms of projector CPU, whichever occurs first. Store/WAL backpressure halves the next batch down to 10; healthy drains increase it additively to 10,000. +- Cross-shard rollups publish only with their full input vector. Queries can distinguish dominated, incomparable, stale, unavailable, and redacted components. + +### Dead letters and advancement policy + +Plan 01 is the sole semantic owner of `DeadLetterReasonV1`, `DeadLetterDispositionV1`, `DeadLetterRecordV1`, `DeadLetterAttemptV1`, `DeadLetterResolutionReceiptV1`, `DeadLetterCompactionV1`, and `DeadLetterPageV1`. This crate selects those values; it does not redefine them. Plan 02 is the sole repository/physical owner and derives the operator view's attempt count, next retry, and terminal resolution by joining the immutable record to its append-only attempts/resolution. + +Dead letters persist in plan 02's `dead_letters` family in the owning shard ([`02-store-crate.md`](02-store-crate.md)), keyed by the full `(projector, projector_version, shard, generation)` checkpoint key plus sequence/input. Growth is bounded without deletion of live evidence: resolved dead letters older than the evidence-retention watermark compact into immutable per-`(projector, reason, day)` rollup counts, unresolved blocking records are never compacted, and a per-shard live envelope of 100,000 records or 256 MiB raises backpressure on the offending projector — never silent discard. + +Before any `put_row`, graph label/snippet, FTS document, representation source, aggregate label, replay artifact, or emitted outbox payload, `privacy.rs` verifies the source receipt/descendant lineage and requires the corresponding domain sink-eligible wrapper. Receipt verification reads the durable `SanitizationReceiptV1` rows in plan 02's per-shard `sanitization_receipts` table ([`02-store-crate.md`](02-store-crate.md)); capture mints receipts per [`03-capture-crate.md`](03-capture-crate.md), and the table's expiry/revocation state is what "expired" and "revoked" mean here. `privacy.rs` never turns raw/classified text into an eligible value. A missing, incomplete, incompatible, expired, or revoked receipt blocks the checkpoint or emits a non-content coverage row according to the registry; it can never be coerced into empty text and counted as complete. + +- Registry, sensitivity, identity, evidence, invariant, corrupt-input, ownership, and outbox-gap failures block by default. +- `DeadLetterDispositionV1::QuarantineAndAdvance` is legal only for a registry-declared optional forensic family whose omission is surfaced in projection coverage; canonical messages, tools, reasoning markers, goals, agents, LCM lineage, Git, and automation cannot use it. +- Dead-letter create/attempt/resolution/compaction are typed `DeadLetterMutationV1` values committed by plan 02's projection repository. A blocking failure and unchanged checkpoint commit together; a replay resolution, its registered effects, its receipt, and any now-legal checkpoint advance commit together. Deleting or editing a live dead letter is forbidden; the only removal path is the retention-watermark compaction above, which preserves the rollup counts. +- Rebuild validation fails on unresolved blocking dead letters and reports quarantined omissions by kind/count/hash. + +### Rebuild and atomic swap + +```rust +pub struct RebuildRequest { + pub projectors: Vec, + pub shards: Vec, + pub target_watermark: VectorWatermark, + pub reason: RebuildReason, + pub retain_previous_generations: u8, +} + +pub struct ProjectionRebuilder { + store: S, +} + +impl ProjectionRebuilder { + pub fn preflight(&self, request: &RebuildRequest) -> Result; + pub fn build(&self, request: RebuildRequest) -> Result; + pub fn validate(&self, build: &BuildGeneration) -> Result; + pub fn publish(&self, build: BuildGeneration, manifest: ProjectionManifest) -> Result; + pub fn rollback(&self, receipt: &SwapReceipt) -> Result; +} +``` + +- Preflight requires old generation + new generation + 25% disk headroom and records evidence-retention limits before work starts. +- Build reads a frozen vector watermark, writes only a new generation, checkpoints every bounded batch, and resumes by manifest hash. +- Validation checks deterministic counts/hashes, registry coverage, referential/bitemporal/DAG invariants, privacy gates, dead letters, and domain parity. +- Publish atomically updates one manifest pointer after fsync; existing readers retain the old generation until their handles close. A failed publish leaves the old pointer active. +- Rollback atomically points to the previous validated generation.

Native thread/session/turn IDs and ordinals remain aliases/queryable; one provider thread may span sessions and one imported session may have ambiguous thread candidates without collapsing either identity. Generic chats require no project. +2. **Agent graph:** actor -> agent instance -> presence/work claim -> parent/child spawn -> inter-agent message -> handoff -> workflow membership/lifecycle. Claim scope connects repo/worktree/ref/PR/file/symbol/query anchors; provider/user declarations remain distinct from inferred material-overlap candidates. +3. **Turn activity graph:** each canonical Turn is the hub for human/assistant messages, provider-exposed reasoning artifacts, tool invocations/results/approvals, file operations, goals/tasks, usage, diagnostics, tests, and produced artifacts. +4. **Provider workflow graph:** Claude workflow runs, roster agents, journal status, results, and handoffs retain Claude/native kinds while also projecting canonical `WorkflowRun`, `AgentInstance`, and `Handoff` entities. Codex goals retain create/update/complete/blocked, objective, budget, and status semantics while also projecting canonical `Goal`/`Task` versions. Neither provider model is forced into the other. +5. **Evidence graph:** Turn/session/agent/workflow/goal entities cross-link through `RelationAssertionV1` to timeline events, worktrees/branches/commits/PRs/checks, code snapshots/files/symbols/diagnostics/tests, facts/retrieval/feedback/memory versions, hints/policy evaluations, and automation artifacts/outcomes. + +The timeline is an ordered view over canonical events and graph relations, not a separate source of truth. A Turn uses a provider-native turn ID when available; otherwise its stable identity derives from canonical session ID plus native ordinal/source position. Multiple messages or tool events may belong to one Turn. Late records append versions/relations and keep occurred/ingested ordering evidence; they never renumber established Turns. + +Code graph federation has an additional hard key: `(repository, checkout, optional worktree, optional ref, snapshot, graph generation, source watermark)`. `code_evidence_v1` emits and validates that tuple for every graph occurrence/index row. A ref is a movable locator and may share a snapshot/generation with other refs; it never owns a database. Cross-repository and cross-generation edges are separate evidence-bearing relations with both endpoint tuples and independent freshness. Missing, stale, quarantined, or ambiguous tuple components remain coverage/candidates. Neither the active base checkout nor the currently published graph may substitute for a selected PR worktree/ref/generation. + +Hermes concepts project at two levels: + +- Host/user/agent/automation identities become explicit `Actor` and `AgentInstance` entities with source aliases; the user-profile consolidation from PR #407 governs storage ownership. +- Session reflector, skill writer, memory curator, combined review, and related automation runs become canonical `AutomationRun`/`WorkflowRun` entities while retaining native task/backend/status labels. +- Candidate, validation, autonomy-decision, automatic-effect, archive, fact, skill, artifact, feedback, adoption, outcome, and recovery records form V2 curation/self-improvement evidence chains. Imported historical/provider proposal/approval/rejection/apply events remain distinct labeled predicates with direct evidence but never become a V2 gate. +- Adoption/effectiveness is never inferred merely because a skill/fact existed before a later session; policy/outcome projectors require the recorded usage, retrieval, feedback, or labeled evaluation evidence. + +Required canonical Turn relations are `part_of_session`, `performed_by`, `contains_message`, `contains_reasoning_artifact`, `invoked_tool`, `received_tool_result`, `observed_goal`, `touched_file`, `observed_git_object`, `retrieved_fact`, `emitted_hint`, `part_of_workflow`, and `produced_artifact`.

Registered index-family generations (`fts`, `vector`, `graph`, cluster, summary, and future families) occupy the domain `IndexVersionSet` map. `QueryShardMergeStateV1` is private in-memory merge state; the owning store serializes its bounded opaque continuation into domain `ShardCursorPosition.resume` and binds the captured watermark. It never becomes a second public cursor-position shape. + +`CursorV1` is the query crate's private signing/codec representation of the domain `CursorClaimsV1` ([`01-domain-crate.md`](01-domain-crate.md)); every field and type maps one-to-one and schema tests compare canonical encodings before authentication. It imports `ShardDispositionV1` unchanged. Query/access/scope digests use `PrivacyDomainBoundLocatorDigest`, `AccessPolicyDigest`, and `ScopeSelectorDigest`; no plain content hash or query literal appears in cursor bytes. `StableSortKey` is the in-memory merge key and lowers to `sort_cutoff` plus `last_entity_id` in the claim. + +- Encode canonical CBOR, authenticate with the profile's active cursor HMAC key, then base64url without padding. The envelope prefixes an unauthenticated `key_id` header used only to select the verification key; all claims live inside the authenticated CBOR body. A cursor contains no raw query literal, payload, secret alias, or filesystem path. +- Cursor signing keys have an explicit lifecycle record persisted in the profile catalog/store (shared with plan [`17-official-public-api-and-sdks.md`](17-official-public-api-and-sdks.md)'s contract IR): `CursorKeyRecordV1 { key_id: CursorKeyId, profile_id: ProfileId, state: Active | Retiring | Revoked, created_at: UtcMicros, retire_after: Option, revoked_at: Option }`. Exactly one key per profile is `Active`; new cursors are signed only with it. Rotation moves the previous key to `Retiring`, which still verifies until `retire_after` for at least the maximum outstanding catalog-declared cursor/subscription/export lifetime. `Revoked` keys fail immediately with restart reason `cursor_key_revoked`. Because keys persist in the store rather than process memory, cursors remain valid across daemon restart and upgrade; rotation is an application command that produces the cursor-key rotation receipt archived in Section 18. +- Interactive expiry is plan 20 descriptor `query.cursor.interactive_ttl`, default 15 minutes. Export/bulk continuations use their catalog-declared job lifetime; no adapter supplies an arbitrary duration. +- Resume validates MAC, expiry, query fingerprint, access digest, scope-set digest, catalog generation, temporal clause, intent profile, schema, ranking, index generations, retention horizon, and each shard identity before opening a shard. +- Resuming a fused-rank cursor re-executes every enabled channel over the frozen snapshot (identical index generations and watermarks), re-fuses deterministically, verifies that the re-fused emitted prefix reproduces `emitted_ids_digest`, and then skips past `sort_cutoff`/`last_entity_id`. Per-shard positions bound the rescan work; the recomputation is charged to the resuming request's `CostBudget` and counted in `QueryTiming`. A prefix/digest mismatch returns the typed restart reason `cursor_nondeterministic_resume`. +- `emitted_ids_digest` is a keyed digest over the ordered, already-emitted canonical `EntityRef`s. It verifies deterministic resume; duplicate suppression comes from deterministic re-fusion plus the cutoff skip, never from the digest alone. +- `SortValue` cutoff comparisons use canonical total-order byte encodings (integers and canonical finite `f64` bit patterns; NaN/infinite values are rejected at shard boundaries), so cursor comparisons are platform-deterministic. The `1e-9` tolerance in Section 16 applies only to explain-arithmetic reconstruction, never to cursor cutoffs. +- Retention crossing a frozen watermark, an incompatible shard replacement, or changed ranking/schema/catalog generation returns a typed restart reason. +- A newly unavailable shard is marked unavailable in `shard_dispositions` while other stored positions resume. A shard newly registered after the snapshot is excluded. +- Frozen mode filters every shard at `row.sequence <= captured_watermark.sequence` (or its equivalent immutable generation). +- Equal user-visible sort values are broken by canonical `EntityRef`; ranks never depend on arrival order, SQLite row ID, hash-map iteration, or shard-open order. +- Live delta cursors (`LiveDeltaCursorV1`) are distinct from page cursors and carry the last per-shard outbox sequence plus a duplicate-suppression digest; they share the same key lifecycle and envelope rules. + +## 10.

Correctly pruned out-of-scope/capability shards remain named `skipped` dispositions without making an otherwise complete in-scope result partial. Each canonical coverage disposition retains shard ID/kind, safe project/profile label, requested/captured watermark, schema/capability versions, reason, last successful freshness time, and rows scanned/returned when known. + +Unknown denominators serialize as `value: null, state: "unknown", reason`, never numeric zero. Partial aggregate results include source-watermark vectors. + +## 11. FTS, Vector, Ranking, Graph, and Time Contracts + +### 11.1 FTS + +- `TextQuery` distinguishes phrase, terms, prefix, fields, tokenizer profile, language hint, and compatibility profile. It never accepts raw SQL/FTS syntax. +- V1 compatibility fixtures cover quotes, punctuation, parentheses, operators, path separators, CJK, emoji, empty tokens, prefixes, raw-vs-summary provenance, and LIKE fallback inclusion. +- Store adapters return raw BM25, tokenizer/index version, match fields, token/phrase spans, and fallback mode. Query normalizes but preserves raw values in explain output. +- Sensitive, secret-like/quarantined, locked, and reasoning content excluded by projection policy cannot be recovered through fallback search. +- Field boosts and tokenizer versions belong to `RankingProfile`, not HTTP/MCP handlers. + +### 11.2 Vector + +- `SemanticQuery` requires representation kind, model ID/version constraint, metric, top-k, exact-fallback policy, and permitted sensitivity classes. +- Query vectors come through `RepresentationQueryPort`; consent and model loading occur outside this crate. +- Shards declare `Exact`, `Approximate { algorithm, build_version }`, or `Unavailable`. Exact fallback is mandatory for the versioned eval corpus; production may return named partial semantic coverage when the budget cannot exact-scan. +- Distance normalization is metric-specific and versioned.

TraceDecay releases publish a canonical `representation-artifact-catalog-v1.json` plus detached release signature; entries pin upstream revision, exact bytes, license/notice, tokenizer/runtime ABI, resource envelope, and upstream signature when available. Model bytes are not bundled unless license, size, provenance, and release policy explicitly allow it. +2. Enabling a representation profile is an explicit config/application action naming artifact IDs, allowed network source, disk/RAM/device budgets, privacy domains, and fallback. It may authorize an automatic first-use download; ordinary query execution itself never performs network I/O or widens egress. +3. Download uses an allowlisted HTTPS source, bounded redirects within that allowlist, content length/ETag, resumable private staging, maximum size, release-catalog signature, artifact SHA-256, and optional upstream signature. Verify before atomic publish; mismatch/quarantine never replaces a verified artifact. +4. Profile storage path is `artifacts/representations///` under private `0700` directories and `0600` files. Catalog/state rows contain no URL credential. Offline import goes through the same size/hash/signature/license checks. +5. A runtime lease pins artifact/catalog/runtime/config digests, device, load time, maximum RSS, request count, and owning process. Activation warms outside query/store locks; OOM/load/crash produces explicit coverage and unloads/quarantines according to evidence, never corrupts an index or silently chooses another model. +6. Default budgets are 4 GiB disk cache, 2 GiB aggregate resident model memory, one concurrent cold load, and five-minute idle unload; plan 20 exposes stricter values and hardware-aware validated increases. LRU eviction skips active leases, config pins, in-progress generation builds, and artifacts required by retained exact-eval/replay manifests. Eviction removes bytes only and keeps the signed manifest/state/history. +7. Representation indexes pin artifact, tokenizer, dimension, metric, normalization, builder/runtime, privacy domain, key epoch, input watermark, and build digest. Mixed pins never merge. Revocation marks affected generations unavailable and schedules authorized rebuild; it does not query them or fall back to a different embedding space. +8. Embeddings, learned-sparse values, and rerank caches inherit the source privacy domain/sensitivity and never cross domain/key/residency boundaries. Model input must already be `RepresentationEligibleText`; artifacts receive no raw secret/quarantine/reasoning content and no repository data leaves the machine for inference. +9. Missing/evicted/revoked/OOM/incompatible artifacts return typed semantic-channel coverage. Ranking preserves the exact pre-semantic lexical list when fallback is allowed and names the omission; a profile requiring semantics fails explicitly. +10. Status/doctor/Observatory report catalog vs bytes vs verified vs active, signature/revocation, disk/RAM/device, pins/leases, affected generations, cold/warm latency, fallback frequency, and safe remediation. No metric logs model input/vector values or raw cache paths. + +Application capabilities are `representations.artifacts.list|get|status|install|import|activate|deactivate|evict|verify` and `representations.generations.list|rebuild`; generated CLI/MCP/API/Settings surfaces share these use cases. Install/import/activate/evict are administrative local effects with idempotency and receipts, never hidden inside search. Exact artifact bytes and license notice are exportable only as their original public artifact, not through transcript/data export. + +### 11.3 Ranking + +```rust +#[derive(Clone, Debug, Serialize, Deserialize)] +pub struct RankingProfile { + pub id: RankingProfileId, + pub version: SemVer, + pub rrf_k: NonZeroU16, + pub components: Vec, + pub tie_break: TieBreakPolicy, +} + +#[derive(Clone, Debug, Serialize, Deserialize)] +pub struct RankExplanation { + pub profile: RankingProfileRef, + pub final_score: FiniteF64, + pub components: Vec, + pub stable_sort_key: StableSortKey, +} + +#[derive(Clone, Debug, Serialize, Deserialize)] +pub struct ComponentScore { + pub component: RankComponentId, + pub version: SemVer, + pub channel: Option, + pub raw: FiniteF64, + pub normalized: FiniteF64, + pub normalization: NormalizationRef, + pub weight: FiniteF64, + pub contribution: FiniteF64, + pub state: ComponentState, // Applied | Absent | Excluded { reason: ExclusionReason } +} +``` + +- Fusion is defined once, here, for every consumer (plans 15 §4.3 and 23 §5.3 state requirements against it): within each shard, deterministic reciprocal-rank fusion runs over the enabled candidate channels (lexical, fuzzy, entity, vector, learned-sparse, summary-DAG, temporal, graph); then a calibrated cross-shard merge combines the shard lists — exact-match tiers first, then rank-based merging with a per-shard calibration whose method and version are declared in the `RankingProfile`. Raw shard BM25 scores are never compared as if corpus statistics were shared. +- Fixed-layout determinism is owned by this crate's planner: identical logical inputs, shard layout, generations, candidate budgets, and ranking profile produce byte-identical top-k IDs and explanations. Repartitioning may change bounded candidate recall and rank because fusion is shard-local before calibrated merge; the Section 17 repartition test therefore requires exact-match-tier invariance plus declared minimum top-k overlap/nDCG and explanation of every changed result, not impossible byte identity. Plan 23 §5.3 supplies session fixtures and calibration ablations; a candidate default cannot exceed the locked worst-stratum drift budget. +- Declared finite weights for recency, trust, graph proximity, and usage apply after fusion, only when those features are present and authorized. +- Missing features contribute `Absent`, not zero; profiles declare whether to renormalize or preserve fixed weights. +- NaN/infinite values are rejected at shard boundaries. +- Compatibility profile `v1-memory-2026-07` reproduces `FactRetriever` scoring/order for eligible V1 facts. V2 default is separately versioned. +- Release gates use the calibrate-then-lock relative regime owned by plan 15 §7.1: a candidate default must improve predeclared Precision@3, nDCG@10, and first-useful rank over the locked baselines on the untouched test split, with no material worst-stratum regression as numerically defined in plan 15 §7.1 and no plan 23 §8.6 safety-floor breach. This crate pre-commits no absolute corpus-independent nDCG/recall threshold. + +### 11.4 Graph and time + +- Neighborhood requires explicit edge kinds, direction, evidence classes, confidence floor, depth `<= 5`, node limit, edge limit, and level of detail. +- Path requires source/target sets, edge kinds, maximum depth/cost, maximum 20 alternatives, cycle policy, and stable ordering by path cost then entity IDs. +- Impact/affected-tests is a named profile over evidence-bearing code/delivery relations, not an unrestricted traversal. +- Git/code result roles are disjoint and explicit: `directly_changed`, `structurally_impacted`, `candidate_test`, and `context_only`. Each row carries the producing edge/path/profile, evidence/confidence, truncation, and source/index watermark; transitive/file-level fan-out cannot increment the direct-change count or render as “modified.” +- Traversal stops at privacy-domain/sensitivity boundaries and reports redacted frontier counts without leaking hidden IDs. +- Time predicates distinguish occurred, ingested, valid, observed, and comparison intervals. +- The AST carrier for answer modes is the `TraceQueryV1.temporal` clause (Section 6): the planner lowers `Current`, `AsOf`, `Evolution`, and `Forensic` to shard operators with plan 23 §4.3 semantics; plan 23 rides this clause and defines no parallel AST. +- As-of state uses `valid_from <= t < valid_to` and `observed_from <= knowledge_time < observed_to`; `AsOf` therefore requires both `valid_time` and `knowledge_time` — callers must provide both when asking “what was known then,” and validation rejects a single-timestamp as-of. +- Timeline density uses server-side buckets. Sanitized native/canonical events are never returned unbounded for wide intervals. +- In-memory CSR acceleration is permitted only behind the same bounded operator contract and must produce the same entity/edge set as the store reference implementation. + +### 11.5 Agent proximity and coordination + +```rust +pub struct NearbyAgentsRequest { + pub scope: ScopeSelectorV2, + pub source_agent: EntityRef, + pub source_session: EntityRef, + pub at: UtcMicros, + pub include_same_worktree: bool, + pub include_parallel_worktrees: bool, + pub scope_kinds: BTreeSet, + pub intents: BTreeSet, + pub limit: u16, +} + +pub enum ClaimOverlapKind { + SameWorktree, + ParallelWorktree, + SameRef, + SamePullRequest, + SameFile, + SameSymbol, + SameQueryScope, + SharedRetrievalAnchor, +} + +pub struct ClaimOverlapEvidence { + pub kind: ClaimOverlapKind, + pub left_anchor: RetrievalAnchorId, + pub right_anchor: RetrievalAnchorId, + pub evidence: EvidenceClass, + pub observed_at: UtcMicros, +} + +pub struct CoordinationCoverage { + pub watermark: VectorWatermark, + pub searched_shards: Vec, + pub stale_shards: Vec, + pub unavailable_shards: Vec, + pub redacted_candidates: u64, + pub truncated: bool, +} + +pub struct NearbyAgentHit { + pub presence: AgentPresenceV1, + pub claim: WorkClaimV1, + pub proximity: WorktreeProximity, + pub overlap: Vec, + pub materiality: FiniteF64, + pub declared_redundancy: RedundancyMode, + pub coverage: CoordinationCoverage, +} +``` + +`limit` is `1..=100`; `scope` is the exact caller selector and cannot be narrowed to the source agent's current project/worktree. Only nonexpired current presence/claims appear by default, while historical replay explicitly selects as-of time. Overlap uses typed canonical scopes and retrieval-anchor digests, never summary text alone. Results distinguish same worktree, parallel worktree, same PR/ref, file, symbol, and query scope; carry evidence/watermark/partial state; and do not claim duplication or authority. Coordination Lab reuses this frozen candidate query through application/policy. + +## 12.

No text predicate is required for session/message enumeration (the Section 6.2 `list_sessions`/`list_messages` intents). +- Provider-exposed reasoning is excluded unless policy, retention, authorization, and explicit request all permit it; exclusion is counted in the redaction report. +- Export sink path containment, private permissions, atomic publication, encryption, and job IDs are application/store responsibilities.

Fingerprint-bearing structs deliberately do not derive public `Serialize`/`Deserialize`. Policy's store adapter uses one audited fixed-layout `HintStatePrivateCodecV1` whose encode/decode functions accept/return only these internal types; the codec is unavailable to transport/presentation crates and its bytes live only in the encrypted activity-shard state blob. Public/API/replay views expose counts, category clocks, budgets, decision reasons, and state version—not fingerprint bytes/domain/epoch. Compile-fail tests reject serde/public-view conversion for `PrivacyDomainKeyedFingerprintV1`, `DedupeDecision`, `HintStateSnapshot`, and `HintStateProposal`. Storage envelope: one row per `HintStateTarget`; primary key and uniqueness = the target digest (profile, session, agent, thread); required index on `updated_at`; each set is bounded at 256 entries with oldest-first eviction recorded through `evict_fingerprints`, keeping a row under 32 KiB. Key rotation rebuilds sets from eligible retained evidence or safely forgets them; it never compares epochs. The column-level table schema lands in plan 02. + +#### 9.1.3 DeliveryArbiterV1: the one delivery selector + +`DeliveryArbiterV1` (`src/delivery.rs`) is the single delivery selector for deterministic hints and Plan 22 scout suggestion envelopes. Plans [`07`](07-hooks-crate.md) and [`22`](22-incremental-context-scout-and-suggestion-envelopes.md) cite this section instead of restating selection rules. + +```rust +#[derive(Clone, Debug, Serialize, Deserialize)] +pub enum DeliveryCandidateV1 { + Deterministic(ScoredCandidate), + Scout(SuggestionCandidateV1), // Plan 22 §4.3 +} + +#[derive(Clone, Debug, Serialize, Deserialize)] +pub struct DeliveryArbitrationV1 { + pub invocation_id: HookInvocationId, + pub winner: Option, + pub suppressed: Vec<(CandidateId, SuppressionReason)>, + pub payload: Option, + pub proposal: HintStateProposal, +} + +#[derive(Clone, Copy, Debug, Default)] +pub struct DeliveryArbiterV1; + +impl DeliveryArbiterV1 { + pub fn arbitrate( + &self, + facts: &RequestFacts, + candidates: &[DeliveryCandidateV1], + state: &HintStateSnapshot, + now: UtcMicros, + ) -> DeliveryArbitrationV1; + + pub fn claim_pending_suggestion( + &self, + request: &PendingSuggestionRequestV1, // Plan 22 §11 + state: &HintStateSnapshot, + now: UtcMicros, + ) -> DeliveryArbitrationV1; +} +``` + +At arbitration input normalization, a scout candidate receives the same evaluation-local `CandidateId` derivation using its retained `SuggestionCandidateId`; the source ID remains inside `SuggestionCandidateV1`. Suppression rows therefore use one collision-free ID type without discarding source identity or inventing a durable cross-run alias. + +Arbitration rules: + +- Exactly one arbitration per evaluative hook invocation: deterministic `ScoredCandidate`s and the pending scout envelope (if any) enter the same call and compete under the same dedupe/cooldown/escalation/ledger state. +- At most one winner, therefore at most one `InjectContext` per invocation. A deterministic hint and a scout envelope can never both deliver in one invocation; the loser records a `SuppressionReason`. +- Atomicity and ordering: the arbiter emits one `HintStateProposal` whose `expected_version` is the pinned `HintStateSnapshot.version`; the application commits it with a single compare-and-swap on that version (row owned by [`02-store-crate.md`](02-store-crate.md)). Concurrent `evaluate` and claim paths serialize on this token — the loser observes the advanced version and re-arbitrates or stays silent; it never double-delivers. +- Plan 22's `claim_pending_suggestion` is a `DeliveryArbiterV1` operation, not a parallel CAS: revalidation and the pending-slot claim ride the same version token, and there is no scout-side hint state. +- Ledgers are engine-agnostic: turn/session/token debits apply to both engines; the scout additionally debits `scout_session_ledger` (default limit 4), so the scout per-session quota shares — never bypasses — the common budget state. +- The arbiter is pure: it proposes; application revalidates and applies, exactly like every other evaluator in this crate. + +### 9.2 Retrieval + +Input contains canonical query intent, scope, query-produced lexical/entity/vector/recent candidates with component scores and exclusions, facts/versions/trust/feedback snapshots, index/model/ranking refs, coverage, and counter state as data.

The column-level table schema lands in [`02-store-crate.md`](02-store-crate.md) (attention signals are one of its named derived read-model families); the staleness/attention rollups are observed by [`26-observability-accounting-and-usage.md`](26-observability-accounting-and-usage.md). + +Age tiers are computed from typed per-kind thresholds (mirroring Hermes's per-status `ready/running/blocked/todo` age tables), configured as Plan [`20`](20-configuration-control-plane.md) descriptors; the evaluator reads the tier, never a wall clock.

No I/O intrinsic or arbitrary code execution. +- Compatibility: V1 hint/memory/scheduler/correlation state remains authoritative only until each bounded cutover and remains internal rollback evidence afterward. Live CLI/MCP/hook boundaries require the current protocol/catalog; stale clients and old tool names fail closed. V1 stores remain read-only through the data rollback window. +- Quality: new production files target <=800 lines; `cargo fmt --check`, `cargo clippy -p tracedecay-policy --all-targets -- -D warnings`, and all crate tests pass. + +## 15. Cutover and Rollback + +1. Refresh the normative publication snapshot; record all accepted inputs, regenerate the V1 stores/profile/tool/policy inventory, and record actual master binary/schema/protocol/catalog-generation versions. Do not begin backfill from a pre-adoption, Hermes-local, ownership-ambiguous, or unretired-applied-manifest locator. +2. Compile/hash V1 compatibility bundles and import immutable input/evaluation/state snapshots with source manifests. Dedupe adopted legacy/Hermes data by canonical source/content digest; quarantine conflicts. +3. Enable `v2_policy_shadow` per evaluator. V1 remains effect owner; V2 evaluates the same captured snapshot without injecting, acquiring locks, mutating memory, writing files, or incrementing counters. +4. Compare decisions, payloads, state transitions, correlations, schedule reasons, memory proposals, outcome attribution, latency, coverage, and digests. Block cutover on unexplained gaps, privacy failure, bundle/input loss, or drifted identity/profile provenance. +5. Cut over independently: routing/hints, retrieval, correlation, diagnostics/curation, scheduler, memory. Each receipt records V1 freeze watermark/state hash, active V2 bundle IDs, input/projector watermarks, source profile/shards, feature flag, and rollback procedure. +6. The application curation worker autonomously applies eligible V2 effect plans after transactional revalidation, records policy/config/expected-version/effect/outcome receipts, and automatically revises or recovers on thresholds. Shadow evaluation remains comparison-only and cannot double-apply; there is no manual preview/apply queue. +7. Rollback disables one V2 evaluator, restores V1 state ownership from receipt, and preserves V2 bundle/evaluation/outcome records for diagnosis. Evaluations already recorded retain their bundle IDs/fidelity. +8. Keep V1 implementation/tests and read-only stores through the data rollback window as internal evidence only. Archive bundles, manifests, corpora, parity/calibration/privacy reports, outcome horizons, migration receipts, and rollback-drill results before retirement; expose no old live schema/name fallback. + +## 16.

Hooks may resolve a pinned snapshot; they may not hard-code a second tool catalog. +- tracedecay-application composes captured request facts, authorized query/memory/skill candidates, policy evaluation, evaluation/state recording, and explicit proposed effects. +- [`22-incremental-context-scout-and-suggestion-envelopes.md`](22-incremental-context-scout-and-suggestion-envelopes.md) owns optional asynchronous model/read exploration and durable suggestion envelopes.

Only host/provider-declared typed tool/compiler/result fields can become trusted failure facts; prompt text, pasted logs, and arbitrary tool output remain untrusted content unless independently verified. +- Preserve the exact sanitized injected payload and host response envelope by receipt-bound digest; retain only a locator/digest for provider-owned raw input. +- Support then-versus-now Hint Lab replay without invoking a host or mutating counters/state. +- Make provider support a generated conformance matrix, not scattered match statements. + +## 3.

Many-Agent Ordering, Backpressure, and Crash Semantics + +Many hook processes may arrive for the same profile, session, worktree, or shard. + +- The daemon/capture service is the normal single writer per shard. Hook processes send bounded frames over a private local channel. +- If the daemon is unavailable, capture writes a uniquely named O_EXCL fallback segment, fsyncs the file and containing private directory, and returns its exact durability. Multiple processes never append to a shared unlocked fallback file. +- The writer assigns shard outbox sequence transactionally. Source sequence comes only from provider/native evidence or the capture source ledger; arrival order is not source order. +- Each source/session/agent stream exposes contiguous, duplicate, gap, late, rewrite, and unknown continuity. Cross-stream display uses occurred time, ingested time, producer, source sequence, and event ID only as deterministic presentation order. +- Parent-child/spawn/handoff/tool-result/goal causation requires provider/native references or a later evidence assertion. Same worktree or close timestamps are correlation candidates only. +- Queue thresholds are measured in frames, bytes, age, and disk budget. Tier 1 coalesces rebuildable sync/status notifications; Tier 2 spills all canonical frames durably; Tier 3 disables optional enrichment; Tier 4 returns typed overload for new optional work while preserving canonical capture. +- Prompts, tool activity, approvals, edits, visible reasoning markers, agent lifecycle, goals, hint delivery, corrections, and outcomes are never coalesced or dropped. +- Writer batching is bounded by 1,000 frames, 4 MiB, or 5 ms transaction time. It preserves per-source order while interleaving sources fairly. +- Read snapshots and policy inputs never hold writer locks. Busy/locked state becomes partial coverage or silence, not an unbounded wait. +- Disk-full reserves a small emergency receipt area for typed manifest/keyed-fingerprint/status fields only; it does not pretend payload durability. + +Crash matrix: + +| Kill point | Required recovery | +|---|---| +| Before frame creation | No acknowledgement; host retry is new/duplicate-resolved. | +| After frame write, before fsync | Recovery verifies framing/checksum and discards torn tail; no durable claim. | +| After fsync, before acknowledgement | Retry finds same idempotency key and returns existing receipt. | +| After observation commit, before outbox commit | Impossible: one transaction. | +| After evaluation record, before injection | Delivery state remains pending; retry uses existing decision and delivers at most once. | +| After injection, before delivery record | Host/provider receipt reconciliation yields Delivered or Unresolvable; never guesses ignored. | +| During rewrite/gap repair | Old generation remains queryable; checkpoint does not advance over unexplained gap. | +| During WAL checkpoint/backup | Committed observations survive; repair emits a manifest/receipt. | + +## 11.

Checked-in typed use-case definitions reference domain schemas and declare ownership, effects, scope, freshness, privacy, cost, evidence, compatibility, and transport bindings; generators emit immutable manifests and adapter metadata, while audit extractors compare every live/legacy surface against the catalog. For MCP, the catalog generates the complete protocol-facing tool/resource/resource-template/prompt/completion manifest, capability requirements, JSON Schema 2020-12 input/output schemas, annotations, task support, and list-generation facts; the root MCP adapter owns protocol lifecycle and invokes application ports. The crate never executes a use case, performs discovery I/O at runtime, negotiates a connection, or becomes a second application layer. + +**Tech Stack:** Rust 2024; serde/serde_json; schemars/jsonschema; semver; blake3; thiserror; clap Command introspection in a build/audit binary only; OpenAPI schema fragments; TypeScript/JSON generation; insta/proptest; V2 domain contracts. + +--- + +## 1.

This catalog owns their audience/effect/scope/grant/privacy/egress/idempotency/output metadata and generated bindings; `all/*` and generic tool grants never enable task mutations implicitly. The generated inventory imports every plan-24 operation ID and proves a bijection; it cannot retain only task detail while omitting control, executor, scheduler, graph, or protected-share operations: + +```text +initiatives.list|get|graph|create|update|pause|resume|retire +plans.list|get|diff|create_version|activate|decompose +work_items.list|get|query|context|dependencies +work_items.create|update|replace|retire|link|unlink|assign|reassign|assign_set +work_items.pause|resume|cancel|archive|retry +work_items.record_attestation|record_review|record_decision|record_exception +work_items.handoff|reopen|reverse_transition +attempts.list|get|timeline +attempts.heartbeat|progress|complete|block +task_offers.list|get|accept|decline|revoke +context_packets.list|get|accept +task_notifications.list|get|create|update|delete +executors.list|get|match|register|heartbeat|drain|unregister +scheduler.status|explain|pause|resume|run_once +task_views.list|get|create|update|delete|share.plan|share.start|share.revoke +task_graph.status|doctor|events +``` + +`task_offers.accept` is the sole public command that may invoke atomic attempt/lease/start admission; no `work_items.acquire_lease` binding exists. `context_packets.accept` is the sole fenced command that may advance an attempt's monotonic accepted-packet pointer; the immutable start packet remains separately visible in attempt detail/timeline. Manual attestation/review/decision/exception/handoff/reopen/reversal remain distinct typed commands, not a generic status setter or rollback. Notification create/update/delete are direct validated commands and have no preview/apply aliases. Each row above has an explicit application, CLI, MCP, HTTP, dashboard, Rust, TypeScript, and Python binding or a reviewed audience-specific unavailability disposition. + +Plan [`15-search-quality-evaluation-and-retrieval-research.md`](15-search-quality-evaluation-and-retrieval-research.md) contributes one closed search-evaluation family. These operation IDs are canonical and exhaustive for this slice: + +```text +reads: +retrieval.corpus_versions.list|get +retrieval.qrel_versions.list|get +retrieval.candidate_pools.list|get +retrieval.judgments.list|get +retrieval.adjudications.list|get +retrieval.evaluation_runs.list|get +retrieval.evaluation_reports.list|get +retrieval.profiles.list|get + +commands: +retrieval.corpus_versions.create|freeze +retrieval.qrel_versions.create|freeze +retrieval.candidate_pools.create +retrieval.judgments.record|supersede +retrieval.adjudications.record +retrieval.evaluation_runs.run|cancel +retrieval.evaluation_reports.publish +retrieval.fixtures.promote +retrieval.profiles.publish|activate +``` + +Every read generates catalog, CLI, MCP-tool, MCP-resource/resource-template, HTTP/SDK, and Search Quality UI parity metadata where the surface supports reads; each `get` resource URI resolves the same application view and each `list` remains the semantic list operation rather than abusing MCP `resources/list`. Commands generate CLI/MCP/HTTP/SDK/UI bindings only and never a writable resource. The catalog must not invent `eval`, `benchmark`, `golden`, `retrieval.fixtures.list/get`, or other aliases/use cases absent from the family above; a surface omission requires an explicit reviewed disposition. + +- Stable use-case identity is transport-independent. search, tracedecay tool search, a future HTTP route, a dashboard command, and a skill route can be bindings of one use case rather than five implementations. +- tracedecay-tool-catalog describes use cases and bindings. tracedecay-application implements/orchestrates them. Adapters invoke application ports; the catalog invokes nothing. +- tracedecay-domain owns canonical IDs, schemas, scope, sensitivity, evidence, watermarks, query/cursor, and command semantics. +- tracedecay-policy consumes one immutable ToolCatalogSnapshot and returns routing/evaluation decisions. It cannot patch the catalog during evaluation. +- Generated artifacts are deterministic from definition/schema/legacy-inventory inputs. Their digest participates in policy/hint/replay manifests. +- An unavailable, pending, deprecated, incompatible, stale, redacted, credential-gated, or live-refresh-required capability remains discoverable with a reason; it does not vanish. +- Surface parity means shared semantic request/response/effect/error contracts, not identical presentation. Markdown, JSON, CLI text, and UI may render differently from one typed result. +- [`20-configuration-control-plane.md`](20-configuration-control-plane.md) owns typed configuration descriptors and effective-value semantics. This catalog generates config bindings and proves full surface coverage; it does not define settings, precedence, or defaults. The config-metadata pipeline runs in exactly one direction: plan 20's registry generator emits `generated/config-registry-v1.json` (typed descriptors plus schema fragments) as an input manifest to this catalog build, the snapshot pins its `ConfigRegistryDigest`, and this catalog is the sole emitter of config CLI/MCP/OpenAPI/SDK/dashboard-form/docs surface metadata; plan 21 renders only from these catalog artifacts. +- [`21-cli-mcp-tool-surface-and-output-unification.md`](21-cli-mcp-tool-surface-and-output-unification.md) owns the exhaustive current CLI/MCP/output audit and generated binding/presentation parity contract.

This catalog declares the generated `representations.artifacts.*` and `representations.generations.*` capabilities, effects, config dependencies, availability, and typed views; it never downloads, verifies, loads, or evicts an artifact. +- PR #410's direct_user/subagent/tool_result filters and parent-representative dedupe are semantic query capabilities, not presentation-only toggles. +- Git output distinguishes directly_changed, structurally_impacted, candidate_test, and context_only. Transitive/file-level graph fanout can never be labeled direct modification. + +## 2.

Curation item effects are autonomous and have no approval/apply binding. +- Give policy compact, versioned task-to-capability facts without shipping the entire catalog in every hint. +- Catalog current agent-presence/work-claim publish, heartbeat, nearby-query, overlap acknowledgement/handoff, coordination analytics, and Coordination Lab capabilities with advisory/privacy/TTL/trigger semantics. +- Route Git intent to branch_list, branch_search, branch_diff, pr_context, changelog, commit_context, sessions_for, and workflows with exact local/live/joined truth requirements. +- Reconcile local semantic Git state and live GitHub/delivery state by ref/merge-base/head/changed-file universe/fetched-at/index watermark. +- Detect catalog drift in CI whenever a surface is added, removed, renamed, or semantically changed without a catalog/version/parity disposition. +- Preserve V1 behavior as differential/import evidence until each cutover, but publish no old runtime tool names, aliases, response-handle quirks, or stale client schemas afterward. Current capability metadata is authoritative. +- Make missed capability, fallback, user correction, unavailable capability, and useful silence observable outcomes. + +## 3. Non-Goals + +- No use-case execution, application orchestration, storage/query/policy logic, provider API call, Git/GitHub call, filesystem scan at runtime, dashboard rendering, MCP transport/lifecycle/session state, CLI parser, or Axum router. +- No dynamic plugin marketplace or remote catalog service in the first V2 default. +- No guarantee that every transport exposes every capability. Absence requires an explicit binding disposition and rationale. +- No prose-only routing rules. Prose docs are generated from typed metadata. +- No arbitrary user-authored executable catalog entries. Managed skills may reference registered capabilities but cannot create hidden commands. +- No silent alias reuse after incompatible semantic change. Breaking behavior gets a new use-case major version or replacement ID. +- No conflation of tool invocation with capability success, hint delivery with use, or a skill file's presence with adoption. + +### 3.1 Convergence boundary + +The catalog is the sole capability/use-case/binding metadata authority in [`19-system-defragmentation-convergence-and-extensibility.md`](19-system-defragmentation-convergence-and-extensibility.md) and the contract-generation input for the official API/SDK plan [`17`](17-official-public-api-and-sdks.md).

They are not application/public business errors. Runtime content cannot enter `CatalogText`; Plan 18 receipts/eligibility appear only as referenced schema and availability requirements. + +## 4. Current and Future-Master Inputs + +The initial inventory is a timestamped compatibility snapshot, not an eternal count. The canonical counts are 104 source MCP tool definitions at `origin/master` `9f7a1108`, 103 installed at `tracedecay 0.0.47` (which lacks source-defined `move_symbol`; `ast_grep_rewrite` is host-conditional), and 102 at the older frozen compatibility inventory captured on 2026-07-09 from the then-installed binary; the root CLI exposed the commands in Section 5. Live stores and branches continued changing during planning; every generated manifest records binary version, commit, profile, fetched/index watermarks, timestamp, and source digest. + +Refreshed implementation inputs: + +- The inspected base `99ad19bc` contains merged PR #405 legacy identity-store adoption and #412 daemon/update drain safety. Catalog definitions use adopted identities once and declare lifecycle drain/checkpoint/service-state prerequisites for update/doctor/daemon mutations. +- PR #407 user-profile Hermes consolidation: Hermes skill/memory/automation capabilities belong to the normal active user profile. Removed Hermes bridges/config/inventory are migration aliases, not V2 extension points. +- Merged PR #410 copied-subagent prompt collapse adds direct_user, subagent, tool_result, and parent-representative filters consistently while retaining every sanitized native row and explicit coverage. +- Merged PR #411 foreign-skill ownership makes doctor/removal/update share one ownership predicate; catalog remediation metadata distinguishes actionable-by-this-installation, manual-user-only, and no-action. +- Merged PR #414 adds the `move_symbol` edit capability; regenerate the tool/CLI/API inventory and require owner/schema/scope/effect/idempotency/inspect/commit/error bindings rather than treating the old 102-name count as current. +- Merged release PRs #413/#416/#418 and merged #407/#415/#417/#419/#420/#422/#423/#424/#425 remain historical inputs; PR #409 remains closed historical inventory only. The normative publication snapshot is [master §2.6](../2026-07-09-tracedecay-brain-rewrite.md#26-current-master-accepted-changes) plus [plan 13](13-research-provenance-and-context-anchors.md). Untracked branch-graph recovery, divergent-session preservation, bounded consolidation lookup, lifecycle-lease-safe hooks, conflict-safe registry reconstruction, read-only FTS search, graph peer-checkpoint safety, and proof-gated retirement of applied consolidation manifests remain required catalog fixtures. + +The implementation lead refreshes master/open PRs and regenerates all legacy inventories before PR 22A. A changed count is expected; an unexplained capability is not. + +## 5. Complete V1 Surface Inventory Baseline + +Plan 21 §§3–4 own the exhaustive current CLI/MCP audit and are the arbiter whenever inventories disagree; this section is the frozen fixture snapshot that catalog-gen consumes, and it must stay consistent with plan 21's tables rather than becoming a second drifting audit. + +### 5.1 MCP/tool surface: 104 source names + +The PR 22A fixture locks all 104 source definitions below; 103 are installed at `tracedecay 0.0.47` (which lacks `move_symbol`), and the older frozen inventory listed 102, omitting both `ast_grep_search` and `move_symbol`.

Stable integer codes and `snake_case` wire names are emitted with the catalog snapshot; plans 21 and 26 consume those generated values and may not maintain SQL-, renderer-, or telemetry-local surface lists. A genuinely new surface requires a catalog-schema version, compatibility disposition, accounting classification, and conformance fixtures before any binding can use it. + +`McpBindingSpecV1` exists only when `surface == SurfaceKind::Mcp`. It classifies the binding by the MCP interaction model: model-controlled operations are tools; application-controlled context is a resource or parameterized resource template; user-selected workflow recipes are prompts. Completion is legal only for prompt arguments and resource-template variables, never as a private tool-argument completion protocol. Tool annotations are generated from `EffectSpec`, idempotency, and egress metadata and remain advisory wire hints; authorization never trusts them. `task_support` describes MCP protocol task augmentation for a long-running invocation, not plan 24's canonical `WorkItemId` or `ExecutionAttemptId`. + +`ExecutionModeV2` lives in this crate's `effect.rs` and is the only closed effect-mode enum; plan 21 §11.1 consumes it for surface annotations and defines no surface-local variant. `SurfaceInvocationCode` carries the current canonical surface name or route only; V1 names live solely inside `CompatibilityDisposition` (field contract defined in plan 21 §17.1) and `CatalogAlias` provenance rows. `PresentationId` replaces any binding-local view reference; presentation descriptors themselves are plan 21's. + +`CatalogAlias` is an intent/search/provenance label inside a snapshot, not a callable MCP/CLI/HTTP/hook binding name. Only `SurfaceBinding` can be invoked, and generation includes only bindings active in the current protocol epoch — `schema_version` plus the exact plan-01 `CatalogSnapshotRefV1` pinned in `ToolCatalogSnapshot` (Section 9). + +Validation fails on: + +- duplicate ID/binding/name/method+route; +- unknown schema/intent/capability/use-case; +- binding request/response fields not losslessly mapped; +- mutation without execution-mode/effect-owner/idempotency/audit/confirmation/recovery disposition; +- destructive effect presented as read or implicit dry-run; +- query/list without bounded pagination/cap; +- live/semantic/joined Git output without freshness/evidence; +- diagnostic/hint route whose required typed input trust can be satisfied by arbitrary prompt/log text; +- sensitive output without access/redaction rules; +- deprecated item without replacement/end window; +- skill/hook route to unavailable or incompatible host capability; +- transport-only semantics not represented in the use-case definition; +- MCP binding without exactly one primitive contract, generated JSON Schema 2020-12 input/output mapping where applicable, compatible protocol revision, and matching capability declaration; +- completion on a tool, subscription on a mutable resource without an authorization-safe change source, tool task support without an application operation/cancellation/result contract, or an MCP task ID mapped to a plan-24 domain task ID; +- MCP tool annotations that disagree with effect/idempotency/egress metadata, or authorization/policy that relies on those advisory annotations; +- search-evaluation binding outside the closed Section 1 `retrieval.*` family, missing CLI/MCP/resource/UI parity metadata, an MCP resource that mutates state, or any alias that creates a second operation identity; +- scoped binding without `ScopeSelectorV2`, or any current-project/CWD/first-match/base-checkout/current-graph fallback; +- current inventory item with no owner/parity disposition. + +## 9.

Its generation is the monotonic per-daemon-generation counter negotiated in the MCP handshake exactly as master plan §2.6 (merged #422) and plans 12/21 describe: a daemon increments it whenever it activates a different snapshot digest, and each MCP session pins the pair unchanged. This crate emits list generations and capability requirements; plan 21's connection actor owns negotiation, refresh, and delivery. It advertises `tools.listChanged`, `resources.listChanged`/`subscribe`, or `prompts.listChanged` only when the corresponding generated primitive and notification implementation exist, and coalesces at most one `notifications/*/list_changed` event per primitive generation per session. A paginated list cursor pins one generation across every page. A client holding a stale snapshot fails closed with plan 17's typed `client_update_required`/`daemon_restart_required`/`capability_replaced` codes naming the current binding; it never receives a silently different tool/resource/prompt set. `config_registry_digest` pins plan 20's registry manifest that this snapshot was built from. + +The planning protocol baseline is the current stable MCP revision `2025-11-25`; PR 22A refreshes that revision from the official version registry and pins it in `mcp-protocol.json`. Draft revisions never enter a release artifact implicitly. The V2 live catalog generates no `2024-11-05` compatibility surface: incompatible clients receive the current supported revision during initialization and must reconnect/update before any application or store access. + +RouteResolution returns ranked available candidates, unavailable candidates with exact gaps, required freshness/evidence source, safe fallbacks, expected cost/latency, and catalog digest. It does not classify natural language or invoke tools. + +`AvailabilityContext.scope` is the exact shared selector and `scope_resolution` is the matching catalog/store snapshot pinned at `local_watermark`. Route resolution preserves every selected repo/project/checkout/worktree/ref/snapshot/generation tuple, returns ambiguity/stale/quarantine coverage, and never narrows to `project_key`, first CWD, active base checkout, current branch graph, or registry first match.

Non-curation commands use typed execution contracts and, when destructive, an operation-specific inspect or immutable plan followed by confirmed start/commit; all commands use idempotency, optimistic aggregate versions, one owning-shard unit of work, one authoritative canonical command-event journal, referenced audit/outbox entries, and resumable workflows for cross-shard effects.

No root/adapter/dashboard module may become a second query engine, scheduler, event journal, or lease authority. Those task/plan reads and commands are enumerated in the Section 9–10 inventories below; every task mutation is a POST command-envelope use case (plan 10 §8.7) with no PATCH transport shape. + +- The application crate owns use-case identity, authorization, orchestration, request deadlines, non-curation command execution/confirmation, autonomous curation effect application, idempotency, optimistic versions, audit requirements, export/job lifecycle, and bounded migration dispatch. +- `tracedecay-domain` owns canonical IDs, scope, evidence, sensitivity, watermarks, the sole `TraceQueryV1` AST, and command envelopes. Application types wrap these contracts; they do not create task selectors, board DSLs, or string substitutes. Task convenience inputs compile losslessly to registered values in `TraceQueryV1` and expose the canonical digest. +- `tracedecay-query` owns planning, federated reads, ranking, cursors, exports bytes, and live snapshot/delta semantics. Application authorizes and selects query profiles; it does not inspect SQL or re-rank rows. +- `tracedecay-policy` owns deterministic evaluation and proposed effects. Application assembles immutable inputs, invokes the runtime, and transactionally revalidates effects. The curation worker then autonomously records/applies eligible owned memory/fact/skill/profile-curation effects; it never waits on a per-item preview/approval/apply action. +- `tracedecay-tool-catalog` owns declarative capability metadata and generated transport mappings. Application implements the stable `UseCaseId`s referenced by that catalog and fails CI on missing or duplicate ownership. +- [`20-configuration-control-plane.md`](20-configuration-control-plane.md) owns the configuration registry/resolution semantics. `tracedecay-application::configuration` is their sole resolver and mutation owner; every other application use case consumes its pinned effective digest. +- [`21-cli-mcp-tool-surface-and-output-unification.md`](21-cli-mcp-tool-surface-and-output-unification.md) requires sealed typed semantic views and one typed outcome/page/notice/freshness/provenance contract. Application constructs those views once; transports and renderers cannot repair or reinterpret them. +- [`22-incremental-context-scout-and-suggestion-envelopes.md`](22-incremental-context-scout-and-suggestion-envelopes.md) assigns the daemon's asynchronous context-scout workflow, bounded read/model ports, envelope transactions, status, and exact pending-delivery claim to application; hooks never own its orchestration. +- [`23-session-lcm-temporal-retrieval-and-evaluation.md`](23-session-lcm-temporal-retrieval-and-evaluation.md) assigns authorized temporal search/context/replay/corpus/evaluation use cases to application while query owns ranking and temporal resolution. No adapter performs search-to-load routing or synthesis fallback locally. +- `18-secret-detection-redaction-and-private-data-safety.md` owns the mandatory sanitizer and taint-state types. Application accepts new content as `Unclassified`, invokes the one sanitizer port, and passes only sink-eligible wrappers or typed redacted/denied/unknown states to stores, projectors, policy, audit, transports, exports, and workflows. It cannot bless a raw `String`, JSON value, summary, compatibility row, or error detail locally. +- Store/projector/archive implementations enter through narrow ports or sibling-crate public traits. No connection, transaction, SQL string, filesystem path, Axum, MCP, CLI, React, renderer, or provider hook type crosses this boundary. +- One command transaction has exactly one canonical owning shard. Cross-shard work is an explicit durable workflow with steps, expected versions, idempotency keys, compensations where safe, and partial/failure state; V2 does not emulate distributed atomicity. +- A query may span shards but captures one vector watermark and preserves every stale, unavailable, incompatible, locked, skipped, redacted, sampled, and truncated disposition. +- Labs are read-only use cases. Fixture promotion, policy/config activation, export publication, and non-curation mutations are separate audited commands. Curation labs are inspectors only: the autonomous curation worker applies policy-eligible fact/memory/skill evolution independently, with no per-item preview/apply/rollback UI. +- Canonical transcript enumeration preserves every sanitized native row and is lossless for retained non-secret structure/semantics. Message enumeration/search consumes domain `MessageOrigin`/`MessageView` unchanged, exposing native, representative, human-best-effort, direct-user, delegated-agent, tool-result, and provider-protocol views; query-time dedupe never deletes or rewrites sanitized source observations. +- `All` means the active `ProfileId`. Additional profiles require an explicit collection/scope and separate authorization; there is no implicit Hermes profile. +- Every fact, skill, policy, automation, saved investigation, and annotation carries domain `DeclaredScope`. Profile/zero-project/cross-project instances are activity-owned; explicitly project-scoped instances are project-owned. A selected project, route, working directory, or active filter is never an ownership default, and unresolved scope blocks mutation rather than guessing. +- V1 readers exist only as internal shadow/backfill/parity adapters during bounded migration. Once a use case becomes V2-default, old live MCP/CLI/HTTP/plugin names and schemas are not executable fallbacks; stale clients receive a typed version mismatch with restart/update/current binding guidance. Non-disposable V1 data remains preserved until migration and rollback receipts close. + +## 2. Goals + +- Give every existing and V2 capability one stable, typed application use case shared by HTTP, CLI, MCP, hooks, dashboard commands, automation, and tests. +- Make the default Brain/All reading path, graph-of-graphs lenses, Explorer, Causal Loom, domain workspaces, Observatory, Costs, replay labs, and Evolution Studio compositions first-class use cases rather than UI-side query choreography. +- Enforce authorization and sensitivity before query planning, payload hydration, replay, export, remote refresh, or mutation. +- Make partial coverage, freshness, vector watermarks, retention boundaries, inference/evidence, and redaction impossible for adapters to omit. +- Separate read-only queries from state-changing commands in types, traits, catalog metadata, audit behavior, retry behavior, and transport generation. +- Guarantee idempotent command retry and compare-and-swap aggregate updates without holding database transactions over network, UI, model, GitHub, process, or filesystem work. +- Support many simultaneous agents and readers without one application request retaining a shard read transaction across pages or user think time. +- Preserve V1 behavior evidence through internal parity profiles and differential receipts rather than duplicating V1 service logic or exposing stale live aliases. +- Provide one parity harness proving identical application semantics across in-process, HTTP, CLI JSON, MCP JSON, dashboard client, export, and subscription transports. +- Make every user-visible mutation produce a durable command receipt and audit event linked to actor, scope, request, preview, applied version, resulting events, and any workflow. + +## 3. Non-Goals + +- No transport parsing, HTTP status selection, SSE framing, markdown rendering, terminal formatting, browser state, or dashboard visualization code. +- No SQL, database migration, WAL/lock management, blob path manipulation, source parsing, projection, ranking, policy bytecode, Git command, GitHub call, provider hook acknowledgement, or daemon lifecycle implementation. +- No general distributed transaction coordinator. Cross-shard workflows expose progress and compensation rather than promising all-or-nothing completion. +- No hidden chain-of-thought reconstruction. Reasoning use cases can return only retained provider-exposed artifacts and unavailable/redacted coverage. +- No arbitrary remote write actions in the first V2 default. Live GitHub/delivery refresh is read-only and allowlisted; PR mutation remains outside scope. +- No ambient authorization, clock, active profile, current directory, process environment, or random idempotency behavior. Adapters/composition supply every request fact explicitly. +- No direct application mutation from replay labs or preview endpoints. + +## 4.

Relative query times, command expiry, cursor validity, policy effective time, audit time, and authorization decisions derive from that value. No use case reads the ambient clock. `CoverageReportV1` is plan 01's canonical shared coverage type, consumed unchanged. + +`AuthenticationClass` and `GrantSet` are concrete contracts, not open strings: + +```rust +pub enum AuthenticationClass { + BrowserSession, // plan 10 §10.2 cookie + CSRF + BearerToken { token_id: ApiTokenId }, // scoped/TTL/revocable registry token, plan 17 §18.2 + BootstrapLaunch, // per-launch secret; only legal command is auth.tokens.create + LocalProcess { os_user: OsUserRef }, // in-process CLI/MCP composition + InternalWorker, // curation/workflow/scheduler actors with recorded provenance +} + +pub struct GrantSet { + pub capabilities: BTreeSet, // Read | Preview | Mutate | Admin | named destructive grants + pub scope_constraints: Vec, + pub sensitivity: SensitivityGrantSet, + pub expires_at: Option, +} +``` + +Composition mints the in-process `Principal` for CLI and MCP adapters: it verifies the invoking OS user against the profile owner, resolves the operator's local token grants, and constructs `LocalProcess` principals explicitly. CLI inherits the operator token's grants; local MCP agent hosts default to Read+Preview and receive Mutate/Admin only from an explicit scoped token (plan 17 §17's read-only default for direct agent credentials). No adapter constructs an ambient admin principal, and the per-launch bootstrap bearer (plan 10 §10.2) authenticates only `auth.tokens.create` for the initial admin-class token. + +`ApplicationError` stable codes include `invalid_input`, `client_update_required`, `daemon_restart_required`, `capability_replaced`, `not_authenticated`, `scope_not_found`, `scope_ambiguous`, `scope_denied`, `identity_split`, `ownership_unresolved`, `payload_denied`, `payload_redacted`, `capability_unavailable`, `freshness_required`, `version_conflict`, `idempotency_conflict`, `preview_expired`, `revalidation_failed`, `workflow_in_progress`, `workflow_failed`, `read_only_lab`, `partial_result_disallowed`, `deadline_exceeded`, `cancelled`, `retention_crossed`, and `internal_invariant`. It carries only the canonical safe problem inputs: code, `CatalogSafeText`, retry/restart/current-binding directive, correlation ID, safe scope candidates, invalid fields, optional current aggregate version, and optional operation ref. `identity_split` includes safe candidate/adoption evidence and legal backup/consolidation preview but never maps to “initialize.” Transport status/formatting is plan 10's mapping; no transport creates another semantic error enum. Bounded failure reasons and compatibility errors cross the output-safety seal and never include raw request, command, query, summary, provider error, or secret content. + +Stale-client codes are exactly the plan 17 §12 contract-IR registry — `client_update_required`, `daemon_restart_required`, and `capability_replaced { current_binding }` — with no locally minted variants. `error.rs` also owns the retry classes: `RetryDirective` is the tagged union below (with `RestartDirective` as its restart payload); plan 17 §12 reproduces it verbatim for SDKs and adds no variants. + +```rust +pub enum RetryDirective { + Never, + SameRequestAfter { delay: DurationMicros, condition: RetryCondition }, + RetryWith { canonical_request: CanonicalRequestRef }, + RestartPagination { request_without_cursor: CanonicalRequestRef, reason: CursorRestartReason }, + PollOperation { operation_id: OperationRef, after: DurationMicros }, + RefreshAuth { method: AuthMethodRef }, + UpdateClient { minimum_protocol: ProtocolRef, current_binding: BindingRef, command: CatalogSafeText }, + ResolveScope { candidates: Vec, canonical_request_template: CanonicalRequestRef }, + Resubscribe { snapshot_request: CanonicalRequestRef, reason: ResubscribeReason }, +} +``` + +`ApplicationResponse` requires a sealed `TransportEligibleView` implemented only by generated structs whose content fields use plan 18's `CatalogSafeText`, `SearchEligibleText`, `PromptEligibleText`, `ExportEligibleText`, or explicit redacted/denied/unknown variants. Raw `String`, `serde_json::Value`, and bytes cannot satisfy it. This is a compile-time boundary plus a runtime sanitization receipt check, not a convention left to each use case. + +### 7.2 Query and command separation + +```rust +pub trait QueryUseCase: Send + Sync { + fn id(&self) -> UseCaseId; + fn execute<'a>( + &'a self, + input: I, + context: &'a RequestContext, + ) -> BoxFuture<'a, Result, ApplicationError>>; +} + +pub trait CommandUseCase: Send + Sync { + fn id(&self) -> UseCaseId; + fn execute<'a>( + &'a self, + command: CommandEnvelopeV1, + context: &'a RequestContext, + ) -> BoxFuture<'a, Result, ApplicationError>>; +} +``` + +- Queries do not reserve idempotency keys, append audit mutations, update access counters, or apply policy effects. Optional view-access analytics are a separately submitted event after the read and never change the returned snapshot. +- Commands always have a canonical owner, idempotency key, expected version, authorization decision, audit schema, and catalog-owned `ExecutionModeV2`. Direct commits execute once; autonomous policy effects are not public item commands; resumable workflows return an operation; host lifecycle events remain internal. A destructive operation exposes a separately named typed preflight use case and a separately named confirmed domain command (for example `storage.consolidation.plan` then `storage.consolidation.start`) whose payload carries the preflight receipt/token. There is no universal `preview`, `apply`, `dry_run`, or `ApplyConfirmation` method. +- An operation-specific preflight captures aggregate/evidence versions, impact, redactions, disk/network/process effects, and a typed confirmation token. The confirmed domain command revalidates every version/capability/hold/freshness dependency; operations that do not need this safety boundary do not manufacture a preflight. +- Retrying an identical completed command returns the stored receipt. Reusing an idempotency key with a different canonical command digest returns `idempotency_conflict` without mutation. +- Adapters cannot invoke repository operations directly; the use-case registry is the only executable capability surface. + +Query inputs embed one typed read envelope; adapters map it losslessly instead of inventing per-transport consistency semantics: + +```rust +pub struct ReadRequirementsV1 { + pub consistency: ReadConsistency, // Eventual | Frozen | AtLeastWatermark(VectorWatermark) + pub budget: ResourceBudget, // row/byte/shard/time caps within catalog hard limits + pub payload: RequestedPayloadPolicy, +} +``` + +This is plan 17 §11.1's per-request consistency/budget/payload contract. HTTP read POST bodies carry it as a top-level `read` object and GET enumerations accept only its bounded enum/watermark forms (plan 10 §8); the request deadline itself stays in `RequestContext`. + +### 7.3 Authorization and privacy + +```rust +pub trait AuthorizationPort: Send + Sync { + fn authorize_query<'a>( + &'a self, + principal: &'a Principal, + use_case: UseCaseId, + requested: &'a RequestedAccess, + ) -> BoxFuture<'a, Result>; + + fn authorize_command<'a>( + &'a self, + principal: &'a Principal, + use_case: UseCaseId, + requested: &'a RequestedEffect, + ) -> BoxFuture<'a, Result>; +} +``` + +- Authorization happens before scope expansion, query planning, payload hydration, policy snapshot load, remote refresh, export staging, or command preview. +- Scope authorization yields profile/privacy-domain/sensitivity grants and an `access_digest` bound into cursors, subscriptions, previews, exports, and recorded evaluations. +- Locked stores return catalog-safe coverage only. Reasoning payload requires an explicit retained-artifact grant and remains excluded from search/export by default. +- Secret-like/quarantined content is never eligible for query text, policy fixtures, fact apply, search/vector projection, or export. Application cannot override that invariant. +- Cross-profile collections authorize each profile independently and return segregated coverage; content is never copied into the catalog to simplify joins. +- New content-bearing commands, model summaries, remote payloads, V1 compatibility rows, operator notes, and generated failure details enter as `Unclassified` and must receive a complete `SanitizationReceiptV1` before inspection result, audit, or persistence. Scanner timeout, incomplete parsing, unsupported encoding, or missing policy returns blocked/unknown coverage and persists only a non-content receipt. +- `privacy.status` derives configured policy, effective safety floor, adapter/source/sink/detector coverage, scanner versions, last verified scan, sanitized/quarantined/legacy-unscanned counts, and unknowns independently. The existence of a historical lossy row is never evidence that protection is enabled. + +## 8. Unit of Work, Idempotency, Audit, and Workflow Contracts + +### 8.1 Single-owner command transaction + +```rust +pub trait UnitOfWorkFactory: Send + Sync { + fn begin<'a>( + &'a self, + owner: ShardRef, + command: &'a CommandIdentity, + ) -> BoxFuture<'a, Result, CommandStoreError>>; +} + +pub trait UnitOfWork: Send { + fn load_aggregate(&mut self, target: AggregateRef) + -> Result; + fn reserve_idempotency(&mut self, reservation: IdempotencyReservation) + -> Result; + fn append(&mut self, event: CanonicalEventV1) + -> Result<(), CommandStoreError>; + fn append_relation(&mut self, relation: RelationAssertionV1) + -> Result<(), CommandStoreError>; + fn append_audit(&mut self, audit: AuditEnvelopeV1) + -> Result<(), CommandStoreError>; + fn append_outbox(&mut self, entry: OutboxEntryV1) + -> Result<(), CommandStoreError>; + fn complete_idempotency(&mut self, result: StoredCommandResult) + -> Result<(), CommandStoreError>; + fn commit(self: Box) -> Result; +} +``` + +Transaction order is fixed: + +1. Authorize the requested effect and resolve canonical owner without opening a writer transaction. +2. Build preview from a frozen read snapshot; return impact, required approvals, and digest. +3. On apply, validate confirmation and deadline, then perform any safe external preflight outside the transaction. +4. Open one owning-shard unit of work and fence the writer lease. +5. Reserve idempotency; exact prior completion returns the prior receipt. +6. Load aggregate and compare expected/preview versions, holds, permissions, and policy/capability digests. +7. Append immutable canonical domain events/relations, audit event, outbox entries that reference their causing canonical event IDs, and stored command result atomically. +8. Commit and return `CommandReceipt` with resulting aggregate version and shard watermark. +9. Trigger asynchronous projections or a durable workflow after commit; never claim their completion in the command receipt until their own receipt exists. + +No network, process launch, source scan, blob upload, large export encoding, model evaluation, or user wait occurs between steps 4 and 8. + +The canonical event journal is authoritative. Current rows and specialized histories are transactionally maintained indexes; projectors, scheduler, replay, and subscriptions advance only from committed canonical event sequence/checkpoints. Outbox entries carry post-commit wakeup or external-effect delivery intent plus causing event IDs; notifier, adapter receipt, audit, SSE, or outbox delivery state cannot create task/domain truth or acknowledge a command that the journal did not commit. + +Idempotency records are concrete contracts, not conventions; plan 02 stores them in the owning shard's `command_idempotency` table: + +```rust +pub struct IdempotencyReservation { + pub key: IdempotencyKeyV1, // caller-supplied, <=128 bytes + pub principal: ActorRef, + pub use_case: UseCaseId, + pub command_digest: ContentDigest, // canonical CommandEnvelopeV1 digest + pub reserved_at: UtcMicros, + pub retain_until: UtcMicros, +} + +pub enum IdempotencyDisposition { + Reserved, + Completed(StoredCommandResult), + ConflictingDigest { stored_digest: ContentDigest }, +} + +pub struct StoredCommandResult { + pub key: IdempotencyKeyV1, + pub command_id: CommandId, + pub receipt_digest: ContentDigest, + pub receipt: BoundedReceiptBytes, // canonical CommandReceipt encoding, <=256 KiB + pub completed_at: UtcMicros, + pub retain_until: UtcMicros, +} +``` + +- Key scope and uniqueness: the primary key is `(principal, use_case, key)` in the command's owning shard; the same key under a different principal or use case is a distinct reservation, never a conflict. +- Retention: completed results are retained at least 7 days (plan 20 configuration, per command class) and never shorter than the longest declared retry/operation-confirmation window; an index on `retain_until` drives GC. After expiry the key is forgotten and a retry executes as a new command; clients needing longer recovery follow the receipt's `OperationRef`. +- Size: a stored result larger than 256 KiB persists the receipt plus an `OperationRef` instead of inline output; identical retry returns that receipt with the operation pointer. + +### 8.2 Command receipts and conflicts + +```rust +pub struct OperationPreflightV1

An expired preflight returns `operation_preflight_expired` and requires the same named preflight use case again. + +Version conflict returns the current version, changed dependency IDs, safe summary, and, only for a confirmed operation, a new-preflight requirement. It never auto-rebases a destructive command. Idempotent status/run/refresh requests may explicitly declare a merge policy; that policy is versioned in the catalog and fixture-tested. + +### 8.3 Cross-shard workflows + +```rust +pub struct WorkflowDefinition { + pub kind: WorkflowKind, + pub version: SemVer, + pub steps: Vec, +} + +pub struct WorkflowStepReceipt { + pub workflow: WorkflowId, + pub step: WorkflowStepId, + pub attempt: u32, + pub expected_versions: VersionVector, + pub input_digest: ContentDigest, + pub disposition: WorkflowStepDisposition, + pub effect_receipts: Vec, + pub compensation: Option, +} +``` + +Cross-shard workflows cover retention/delete descendants, profile/project settings propagation, export publication, projection rebuild/publish, migration/backfill/cutover, autonomous managed-skill materialization/supersession/recovery, backup/restore, and remote refresh plus local reindex. They obey: + +- Durable state is written before executing the next effect; retries use the same workflow/step idempotency key. +- Each step owns at most one shard transaction or one bounded external effect, never both simultaneously. +- Leases are fenced by epoch. A takeover cannot publish a stale step receipt. +- Compensation is declared only where it is safe and semantic; irreversible content deletion has recovery grace and explicit terminal state, not fictional rollback. +- Partial completion is visible in Observatory and returned by status queries. Other shards remain queryable. +- Cancellation stops before the next step. It cannot undo a committed canonical observation, audit event, or externally completed effect. +- Workflow terminal states are `Succeeded`, `Failed`, `Cancelled`, `CompensationRequired`, or `Blocked`; `Blocked` names the missing authority/version/capability. + +## 9. Complete Read Use-Case Inventory + +The tables below use compact operation slugs to stay readable. They are not a second ID grammar: `tracedecay-tool-catalog` supplies canonical `UseCaseId` (`usecase..`) mappings for current bindings; V1 alias mappings live only in the internal migration manifest. For example, `git.branches.list` maps to `usecase.git.list-branches`. Application code accepts only the generated typed ID and cannot construct it from a slug.

A generated binding may declare a convenience default by inserting an explicit root before invocation: Brain/Observatory use `AllAuthorized { profile_id }`; code-local bindings may use `CurrentInvocation`. The shared application resolver converts locators/current invocation to a canonical selector and returns `ScopeResolutionV2`, including `defaulted_current`; no cwd, last project, route, selected row, or host heuristic overrides any explicit root. +- Repository, project, checkout/worktree, ref, commit/snapshot, and explicit multi-selection are distinct scope kinds. A project filter never becomes durable ownership. +- Every candidate includes opaque IDs, kind, profile, disambiguated `owner/repository/project/worktree/ref` label, path/remotes only when authorized, alias/adoption evidence, index generation, freshness, and partial/unavailable state. +- Same-name repositories/projects/branches are never merged by label. Ambiguity returns bounded candidates and a signed token; selecting one candidate retries the original canonical request in one step without retyping query/filter/time state. +- CLI, MCP, HTTP, dashboard, exports, and saved recipes use the same generated scope request/result and candidate token. Transport display may differ; resolved IDs, candidates/order, provenance, errors, coverage, and retry semantics may not. + +### 9.2 Universal query, Brain, graphs, and timeline + +| Use-case ID | Input/output contract | +|---|---| +| `query.execute` | Authorized `TraceQueryV1` to typed rows/edges/facets/aggregates/cursor/explain/coverage. | +| `search.universal` | Evaluated lexical/exact-phrase/fuzzy/entity/semantic/graph/recency hybrid with explicit origin/kind filters, grouping/dedupe, caps, candidate/rank explanation, and profile/corpus version; embeddings are one optional feature, never presumed beneficial. | +| `representations.artifacts.list/get/status` / `representations.generations.list` | Signed catalog versus local bytes/verification/activation/revocation, license/runtime/resource envelope, leases/pins/cache pressure, affected index generations, cold/warm status, and typed unavailable/fallback coverage from plan 05 §11.2A; never model input/vector values or raw cache paths. | +| `search.benchmark.evaluate` | Read-only execution of one or two ranking profiles over the versioned redacted benchmark corpus with per-slice quality/latency/candidate/coverage deltas and promotion blockers. | +| `entities.batch_get` | Bounded inspector hydration for canonical IDs, evidence, provenance, authorized payload slices. | +| `brain.overview.get` | First-scan claim; focal project/workflow/agent plus initiative/plan/task/attempt/blocker/lease/acceptance clusters; aligned work and domain activity; health strip; feedback loop; unfinished work/resume queue; source watermarks. | +| `brain.lens.get` | One bounded Git/code/thread/agent/turn/timeline/memory/automation-skill graph lens with legal node/edge schema and LOD. | +| `brain.cluster.expand` | Stable aggregate cluster membership/counts, child cursor, denominator, sampling, algorithm/layout version. | +| `graph.neighborhood.get` / `graph.path.get` / `graph.subgraph.get` / `graph.diff.get` | Bounded evidence-filtered neighborhood/path/query-driven subgraph/frozen comparison with confidence, redacted frontier, stable ordering, exact snapshot identities, and legal relation schemas. | +| `graph.impact.get` / `graph.affected_tests.get` | Direct versus inferred impact with algorithm/evidence and source snapshot. | +| `timeline.density.get` / `timeline.events.get` | Bounded buckets or event lanes with hidden/late counts, half-open interval, LOD and cursor. | +| `timeline.as_of.get` | Known state at valid and observed time: scope, context, facts, policies, catalog, goals, delivery, coverage. | +| `timeline.follow_agent` / `timeline.compare` | Stable agent/subagent lanes or aligned sessions/agents/branches/models/policies/time ranges with anchors. | +| `activity.events.get` / `activity.facets.get` | Consequential cross-domain activity and project/domain/actor/kind/health facets over the same event/timeline model, with routine-noise hidden counts and live/frozen coverage; no UI-side merge. | +| `coordination.presence.get` / `coordination.nearby.get` / `coordination.overlaps.get` | Expiring evidence-bearing presence/work claims and nearby-agent overlap across the same or parallel worktrees, refs, files, symbols, tests, goals, and review/delivery surfaces; includes safe compact summary plus research anchors/recipes. | + +Brain, graph, timeline, search, impact, and Explorer accept domain `ScopeSelectorV2` unchanged and return `ScopeResolutionV2`. Every node/edge/row retains repository and snapshot identity; same-name symbols/files/refs never collapse without canonical entity lineage. Cross-repository edges require registered dependency/session/workflow/Git/evidence relations, and each shard contributes explicit provenance/freshness/coverage rather than a synthetic global timestamp. + +Graph-of-graphs selection is one application composition: + +```rust +pub struct InvestigationSelection { + pub scope: ScopeSelectorV2, + pub time: InvestigationTime, + pub selected: Vec, + pub pinned: Vec, + pub lens: GraphLensKind, + pub snapshot: SnapshotMode, + pub lod: LevelOfDetail, +} + +pub enum GraphLensKind { Git, Code, Thread, Agent, Turn, Timeline, Memory, AutomationSkill, Task, Plan } + +pub struct GraphLensResponse { + pub schema: LensSchema, + pub nodes: Vec, + pub edges: Vec, + pub aggregates: Vec, + pub inspector_refs: Vec, + pub timeline_refs: Vec, + pub expansion: Option, +} +``` + +Stable investigation handoff exposes domain `RetrievalAnchorId`; the owning store resolves it to domain `RetrievalAnchorRecordV1` under current authorization. Plan 13's research bundle/context manifest cites those IDs. Application consumes plan 01's portable multi-anchor `RetrievalRecipeV1` unchanged — recipe ID, owning use case, anchor list, optional protected input ref, privacy-domain-bound canonical input digest, scope selector, investigation time, optional message view, schema/catalog/ranking version set, and freshness requirement — and defines neither a second recipe type nor a second anchor record. + +Every session/thread/Turn/message/agent/subagent/workflow/goal/Git result exposes at least one `RetrievalAnchorId` and a safe recipe or protected recipe ref. Research bundles use `ResearchContextAnchorV1` only for implementation provenance; it is not a parallel result-citation model. Recipes contain no literal prompt/query/path secret, cursor, response-handle token, or remote credential. Resolution loads `RetrievalAnchorRecordV1` and returns current identity, source evidence, drift from recorded versions/watermarks, and coverage. Cursors remain page mechanics; V1 response handles may bridge a migration renderer but are never the sole research locator or saved/exported reference. + +Agent proximity is a claim/evidence model, not global truth: + +```rust +pub struct AgentPresenceClaimV1 { + pub agent: EntityRef, + pub host_provider: HostProviderRef, + pub workflow_goal_turn: Vec, + pub repository: Option, + pub worktree: Option, + pub revision: Option, + pub work_claims: Vec, + pub observed_at: UtcMicros, + pub expires_at: UtcMicros, + pub source: EvidenceRef, + pub confidence: Confidence, +} + +pub struct CoordinationOverlapView { + pub agents: Vec, + pub overlap: Vec, + pub proximity: ProximityClass, + pub safe_summary: SafeCoordinationSummary, + pub anchors: Vec, + pub retrieval: RetrievalRecipeV1, + pub actions: Vec, +} +``` + +- `ProximityClass` distinguishes same worktree, parallel worktree/same repository, overlapping branch/ref, direct file/symbol/test/goal/review overlap, and weak temporal proximity. Temporal proximity alone is never a conflict claim. +- Presence expires; missing/expired claims mean unknown, not absent. Safe summaries are bounded, secret-scanned, provenance-bearing, and contain no raw prompts, tool arguments, payloads, sensitive paths, or inferred chain of thought. +- Overlap actions are exactly `inspect`, `message`, `handoff`, `ack`, and `suppress`. Inspect is a read. The others are direct or resumable typed commands with target capability, authority, idempotency, delivery receipt, expiry, and audit; failure to deliver never becomes an acknowledgement. +- Policy may select at most one dynamic coordination hint per eligible overlap horizon. It requires material overlap, ranks an actionable target, includes one stable anchor/recipe, and applies per-agent/pair/work-claim dedupe, cooldown, acknowledgement, suppression, and terminal-outcome attribution. Repeated hook prompts cannot spam the same unresolved overlap. +- Coordination analytics distinguish eligible, material, selected, delivered, inspected, messaged, handed off, acknowledged, suppressed, expired, resolved, duplicate-prevented, and unresolved horizons with coverage/denominators. + +Universal search quality is corpus-evaluated: + +- Retrieval stages are separately observable: exact token/field, exact phrase, typo-tolerant fuzzy, entity/alias, semantic/vector, graph-neighborhood, and recency/activity. Each stage declares tokenizer/model/index/version, candidates, caps, exclusions, and latency. +- A versioned ranking profile combines only available features and explains missing ones. Semantic/vector contribution is enabled only when labeled benchmark evidence improves the declared task slice without unacceptable precision, privacy, latency, or memory regression. +- Origin/kind/provider/session/agent/project/ref/time/sensitivity filters execute before or during candidate generation where legal. Representative grouping/dedupe preserves native membership/expansion and cannot erase a better exact match. +- The benchmark corpus covers exact literals, phrases, misspellings, symbols/entities/aliases, direct-user versus delegated/protocol ambiguity, cross-project concepts, graph-related evidence, recency, no-result, capped, adversarial-noise, and embedding-regression cases. A named cross-repo slice spans Rspack, Rsbuild, and React Router work/benchmarks with same-name files/symbols/branches and known dependency/session/PR evidence. Report MRR/nDCG/Recall@k/Precision@k, zero-result rate, latency, candidate counts, coverage, and per-slice regressions; no aggregate score hides a failing exact-match or repository-disambiguation slice. + +Selecting an entity can request another lens using the same `InvestigationSelection` and frozen watermark. Application does not render or position nodes. It guarantees legal lens schema, evidence-bearing cross-links, stable selection identity, bounded expansion, and table/outline projection fields. + +### 9.3 Sessions, messages, turns, agents, and workflows + +| Use-case ID | Input/output contract | +|---|---| +| `sessions.list` / `sessions.get` | Cursor enumeration without text predicate; provider/host/actor/project/time/goal/workflow filters, participants, coverage, snapshots. | +| `messages.list` / `messages.search` | Cursor enumeration/search with role/kind/provider/time plus domain `MessageOrigin`/`MessageView` filters defined below. | +| `messages.get` / `messages.expand_native` | One canonical row or representative with exact source observations and bounded sanitized-native expansion. | +| `turns.get` / `turns.list` | First-class Turn intervals linking visible context, messages, reasoning artifacts, tools, goals, code/Git/effects and end state. | +| `sessions.replay` | Read-only historical assembly with exact/recorded/best-effort availability and missing-input declarations. | +| `sessions.context_lineage` | LCM sanitized-native/source/summary DAG, compression decisions, payload coverage and source ranges. | +| `agents.list` / `agents.get` | Actor/instance identity, provider-native aliases, lifecycle, parent/child, goals, handoffs, usage and outcomes. | +| `goals.list` / `goals.get` | First-class Codex goals and provider-native objectives with owner agent/session/workflow, versioned status/plan updates, Turns, evidence, terminal state, and coverage. | +| `workflows.list` / `workflows.get` | Claude workflows, Codex goals, TraceDecay automations, Hermes-style curation agents with native semantics and shared relations. | + +Application does not define a second message-filter vocabulary. It consumes domain `MessageOrigin::{DirectUser,DelegatedAgentPrompt,ToolResultProtocol,ProviderProtocol,Unknown}` and `MessageView::{NativeRows,RepresentativeRows,HumanBestEffort,DirectUser,DelegatedAgents,ToolResults,ProviderProtocol}` unchanged. Its output row is named distinctly from the domain query enum: + +```rust +pub enum MessageRowKind { NativeRow, RepresentativeRow } + +pub struct MessageReadModel { + pub entity: EntityRef, + pub origin: MessageOrigin, + pub row_kind: MessageRowKind, + pub representative_for: Vec, + pub representative_rule: Option, + pub suppressed_duplicate_count: u64, + pub source_observations: Vec, + pub raw_expansion: Option, + pub content: SanitizedContentView, +} +``` + +`SanitizedContentView` is a generated tagged availability view—`Available(SanitizedPayload)`, `Redacted`, `Denied`, `Unavailable`, or `Unknown` with safe reason/receipt refs. It is not an independent sanitizer or raw-text wrapper. + +`NativeRows` is the complete canonical enumeration of sanitized rows and is lossless for retained non-secret structure/semantics. `RepresentativeRows` is a query projection that preserves every represented row ID, observation, rule/version, suppression count, and expansion cursor. A client that needs both follows the representative expansion cursor or issues a second `NativeRows` request at the same frozen snapshot; no ambiguous combined count exists. Direct-user, delegated-agent, tool-result, and provider-protocol views are independent of provider `role=user`; unknown origin remains visible in `NativeRows`, `RepresentativeRows`, and `HumanBestEffort` coverage. + +### 9.4 Code, Git, delivery, knowledge, automation, and accounting + +| Family | Stable read use cases | +|---|---| +| Code discovery | `code.search_symbols`, `code.find_exact_symbol`, `code.grep`, `code.context`, `code.files`, `code.callers`, `code.callees`, `code.call_path`, `code.impact`, `code.affected_tests`, `code.test_map`, `code.health`, `code.diagnostics`, `code.diagnose_result`, `code.move_symbol.inspect`. The inspect use case is read-shaped and cannot write or mint edit authority. | +| Git semantic tools | `git.branches.list`, `git.branches.search`, `git.branches.diff`, `git.pr.context`, `git.changelog`, `git.commit.context`, `git.sessions_for`, `git.workflows_for`. Each result states local indexed ref/merge-base/generation/watermark and fallback state. A corrupt/missing optional diagnostics, test-annotation, session, or workflow enrichment returns healthy direct Git/diff context with typed component-level partial coverage and a rebuild anchor; it never aborts the whole answer (FM-117). | +| Delivery truth | `delivery.repositories.get`, `delivery.pull.get`, `delivery.checks.list`, `delivery.reviews.list`, `delivery.releases.list`, `delivery.reconcile`. Live state carries provider/fetched-at/ETag/base/head/cap/coverage separately from local semantic state. | +| Knowledge | `knowledge.facts.list/get/search`, `knowledge.entities.list/get`, `knowledge.trust.history`, `knowledge.conflicts.list`, `knowledge.retrieval.history`, `knowledge.feedback.history`, `knowledge.deletion_impact`. | +| Automation | `automation.jobs.list/get`, `automation.scheduler.status`, `automation.runs.list/get`, `automation.artifacts.get`, `automation.candidates.list/get`, `automation.decisions.list/get`, `automation.effects.list/get`, `automation.outcomes.list/get`, `automation.recoveries.list/get`, `automation.history.list`, `automation.skills.list/get`, `automation.workflow_graph.get`. Imported V1/provider proposals, approvals, and applies appear only as labeled historical records in `automation.history.list`. | +| Research provenance | `research.manifests.list/get`. Manifest reads expose immutable `ResearchAnchorId` entry identity plus each entry's nonempty canonical `RetrievalAnchorId` references; the sole anchor metadata/resolution/recipe operations are inventoried once in §9.1. | +| Search evaluation | `retrieval.corpus_versions.list/get`, `retrieval.qrel_versions.list/get`, `retrieval.candidate_pools.list/get`, `retrieval.judgments.list/get`, `retrieval.adjudications.list/get`, `retrieval.evaluation_runs.list/get`, `retrieval.evaluation_reports.list/get`, `retrieval.profiles.list/get`. Every read names owner, immutable version/cutoff, sanitization state, source/index/model/config/catalog watermarks, coverage, and authorization; protected rationales or examples require an eligible payload policy and never enter list metadata. | +| Tasks/orchestration | `initiatives.list/get`, `initiatives.graph`, `plans.list/get/diff`, `work_items.list/get/query`, `work_items.context`, `work_items.dependencies`, `attempts.list/get/timeline`, `task_offers.list/get`, `context_packets.list/get`, `task_notifications.list/get`, `executors.list/get/match`, `scheduler.status/explain`, `task_graph.status/doctor/events`, `task_views.list/get`. Plan 24 §9.1 owns semantics and module files: reads use read ports only, offer reads are registration-scoped, packet reads are attempt-scoped, `executors.match` is read-only, and `task_graph.events` is a subscription read-model kind under `subscriptions.create`, never a second stream vocabulary. | +| Hints and policy | `hints.evaluations.list/get`, `hints.outcomes.get`, `hints.opportunities.get`, `policy.bundles.list/get`, `policy.coverage.get`. | +| Accounting | `accounting.usage.get`, `accounting.costs.get`, `accounting.savings.get`, `accounting.adoption.get`, `accounting.denominators.get`. Unknown/capped denominators are typed, never zero. | + +Current Git tools are not hidden behind the generic query alone: their stable use cases remain catalog aliases so hint routing can recommend them. `delivery.reconcile` refuses to combine semantic impact with live PR/check claims when head/base/merge-base/changed-file digest drift; it returns `RefreshLive`, `ReindexLocal`, or `RecomputeBoth` as an explicit next action. + +### 9.5 Saved investigations, exports, subscriptions, and labs + +| Use-case ID | Contract | +|---|---| +| `saved_views.list/get`, `collections.list/get`, `annotations.list/get` | Authorized profile content storage; sensitive literals never enter catalog or URL-safe summaries. | +| `exports.get`, `exports.list` | Job state, frozen watermark, parts, hashes, counts, redaction, completeness, expiry; bytes served by API after authorization. | +| `subscriptions.create` / `subscriptions.revoke` | Create authorizes a query/read-model request, captures a snapshot, and returns `SubscriptionId` plus a finite replay contract. Revoke is an idempotent principal-bound command that terminates delivery, releases replay/snapshot pins, and appends an audit receipt; transport disconnect alone is not revocation. | +| `labs.hints.evaluate`, `labs.retrieval.evaluate`, `labs.ingest.evaluate`, `labs.query.evaluate`, `labs.correlation.evaluate`, `labs.scheduler.evaluate`, `labs.memory.evaluate`, `labs.policy_diff.evaluate` | Immutable exact/recorded/best-effort input and typed explanation/diff with no writes. | +| `labs.search_quality.evaluate/compare` / `labs.scope_federation.evaluate` / `labs.privacy.evaluate` | Read-only retrieval-profile/corpus comparison, selector-resolution/shard-plan replay, and reserved/invalid synthetic sanitizer evaluation with exact anchors, versions, coverage, resource costs, and zero live registry/qrel/finding/policy mutation. | +| `labs.coordination.evaluate` | Replay presence/overlap classification, proximity ranking, one-hint selection/suppression/dedupe, safe summary, legal action set, and outcome attribution with exact versions/coverage; message/handoff/ack/suppress are simulated only. | +| `labs.orchestration.replay` | Read-only replay of plan 24 scheduler/executor decisions — readiness evaluation, route resolution, lease-acquisition fencing, and context-packet assembly — against recorded task-graph state with exact versions/coverage; work claims, leases, attempts, and views are never mutated. | +| `labs.evolution.inspect` / `labs.evolution.simulate` | Evidence collection through curator/reflector/skill-writer graph, proposal/version diff, validation, historical corpus simulation, rollout/rollback prediction. | + +Evolution Studio preserves Hermes-style self-improvement as ordinary evidence-bearing actors, goals, turns, tools, artifacts, skills, memories, autonomy decisions, automatic applies, uses, outcomes, revisions, automatic recoveries, archives, and deletions. Simulation is an inspector and never mutates live state; it returns changed decisions/tool routes/outcomes, regressions/wins only where labels exist, unknown horizons, privacy exclusions, and cost/latency deltas. The live autonomous worker does not wait for the inspector. + +## 10. Complete Command Use-Case Inventory + +Every non-curation mutation has an explicit typed execution contract; destructive/irreversible operations use a separately named preflight and confirmed domain command when required. Curation is deliberately different: it is fully autonomous under versioned configuration and emits no per-item preview/approve/apply/rollback commands. The catalog marks autonomy, authorization, expected versions, side effects, monitoring/recovery behavior, job behavior, and audit. + +| Domain | Stable command use cases | +|---|---| +| Projects/indexing | `projects.register`, `projects.update_alias`, `projects.unenroll`, `index.refresh`, `index.pause`, `index.resume`, `watchers.start`, `watchers.stop`. Unenroll returns an operation-specific retained-evidence impact/confirmation and never deletes content implicitly. | +| Runtime/daemon/update | `daemon.start`, `daemon.stop`, `daemon.drain`, `daemon.restart`, `runtime.update.plan`, `runtime.update.start`, `runtime.update.recover`. Drain/update are durable workflows carrying lifecycle lease epoch, accepting/draining/stopped state, in-flight work, checkpoint/receipt, restart requirement, takeover, recovery artifact, and current client-binding version. | +| Diagnostics/repair | `diagnostics.refresh`, `doctor.run`, `repair.inspect`, `repair.start`, `backup.create`, `backup.restore`. Inspect is read-only; start is a confirmed resumable lifecycle-fenced workflow with exact repair kind/input version. Restore is a durable workflow with preflight and recovery point. | +| Store administration | `storage.consolidation.inspect`, `storage.consolidation.plan`, `storage.consolidation.start`, `storage.consolidation.status`, `storage.consolidation.resume`, `storage.consolidation.recover`. This is the operator-only merged-#425 workflow for two nonempty profile shards: fail closed on unsupported/path-or-file-identity holders, freeze/reserve both sources, back up, stage, verify every table/artifact/disposition, cut markers atomically, and return exact recovery. `start` requires the recomputed deterministic confirmation token and administrative grant. It never runs from scheduler, task execution, Settings auto-save, or autonomous curation. V1 `preview/apply` names remain only in the compatibility adapter/inventory. | +| Capture/LCM | `capture.ingest`, `capture.pause`, `capture.resume`, `lcm.compress.plan`, `lcm.compress.start`, `lcm.boundary.create`, `lcm.lifecycle.preflight`, `lcm.lifecycle.repair`. Source offsets advance only through capture/store receipts. | +| Automations | `automation.jobs.create/update/delete`, `automation.run`, `automation.cancel`, `automation.pause`, `automation.resume`, `automation.scheduler.enable/disable`. Run revalidates policy/config/activity/lease before fenced acquisition. | +| Autonomous curation | `curation.run_now`, `curation.pause`, `curation.resume`, `curation.status`, `curation.history`, `curation.pin`, `curation.protect`, `curation.exclude`, `facts.feedback`. Candidate create/update/supersede/archive/quarantine and owned skill validate/materialize/revise/recover are internal autonomous effects, not public per-item commands. Each records artifact/evidence/validation/config/policy/expected-version/staged-monitoring/outcome receipts; foreign-owned targets are skipped. Explicit administrative deletion remains the separate descendant/hold/index/blob workflow. | +| Policy | `policy.publish`, `policy.activate`, `policy.rollback`. Exact artifact validation and immutable registry CAS are required; activation never changes an in-flight evaluation. | +| Representation artifacts | `representations.artifacts.install/import/activate/deactivate/evict/verify`, `representations.generations.rebuild`. Plan 05 §11.2A/PR 14E owns lifecycle semantics. Commands pin signed manifest/digest/license/runtime/config, enforce allowlisted egress and disk/RAM/device budgets, stage/verify before publish, preserve active/replay/index pins, and emit operation/audit receipts; query execution never invokes them. | +| Settings | `settings.profile.patch`, `settings.project.patch`, `settings.integration.patch`, `settings.automation.patch`, `settings.storage.patch`. Inline validation shows declared owner, source/default, restart/reindex/privacy/migration impact before the direct expected-version save; environment-derived values are read-only and storage relocation is a separate durable workflow, never an arbitrary path write. | +| Payload/privacy | `payloads.gc.plan`, `payloads.gc.start`, `retention.run.plan`, `retention.run.start`, `holds.create`, `holds.release`, `entities.retire.plan`, `entities.retire.start`, `privacy.scan.start/cancel`, `privacy.remediation.plan/start/verify`, `privacy.quarantine.hold/release`. Privacy commands use safe finding/scan IDs, elevated grants where required, durable jobs, and candidate-free audit receipts. | +| Projections/migration | `projections.rebuild`, `projections.pause`, `projections.resume`, `projections.publish`, `projections.rollback`, `migrations.backfill`, `migrations.reconcile`, `migrations.cutover`, `migrations.rollback`. | +| Delivery refresh | `delivery.refresh`. Read-only remote fetch into captured evidence; repository allowlist, credential capability, rate/cap state, and fetched revision are audited. No PR write command. | +| Saved investigations | `saved_views.create/update/delete`, `saved_views.share.plan/start/revoke`, `collections.create/update/delete`, `annotations.create/update/delete`. Protected content stays with its declared activity/project owner; sharing creates a separately authorized, redacted, expiring local published view readable through `saved_views.get`, never publishes remotely, and never copies source content into catalog metadata. | +| Research provenance | `research.manifests.create_version`. Appends one immutable successor after validating owner, expected predecessor/version, classification and secret-scan receipts, and every manifest entry's nonempty canonical `RetrievalAnchorId` set; it never creates a parallel evidence locator or resolves `ResearchAnchorId` directly. | +| Search evaluation | `retrieval.corpus_versions.create/freeze`, `retrieval.qrel_versions.create/freeze`, `retrieval.candidate_pools.create`, `retrieval.judgments.record/supersede`, `retrieval.adjudications.record`, `retrieval.evaluation_runs.run/cancel`, `retrieval.evaluation_reports.publish`, `retrieval.fixtures.promote`, `retrieval.profiles.publish/activate`. These are direct expected-version, idempotent commands over immutable/superseding artifacts: freezes never rewrite members; supersession retains the prior judgment; adjudication retains every source label; run/cancel records a durable evaluation operation; report publication exposes only aggregate/redacted output; fixture promotion requires a synthetic or reviewed sanitized manifest plus secret-scan receipt; profile activation revalidates locked promotion gates and never alters an in-flight query. | +| Agent coordination | `coordination.message`, `coordination.handoff`, `coordination.ack`, `coordination.suppress`. Every direct/resumable command targets one presence/overlap claim and stable anchor, checks host/agent capability and expiry, returns the inline disclosed summary/effects with its receipt, records delivery/acceptance separately, and cannot mutate another agent's state without an authorized provider action. | +| Tasks/orchestration | `initiatives.create/update/pause/resume/retire`, `plans.create_version/activate`, `plans.decompose`, `work_items.create/update/replace/retire`, `work_items.link/unlink`, `work_items.assign/reassign/assign_set`, `work_items.pause/resume/cancel/reopen/archive`, `work_items.record_attestation/record_review/record_decision/record_exception/handoff/reverse_transition`, `work_items.retry`, `task_offers.accept/decline/revoke`, `attempts.heartbeat/progress/complete/block`, `context_packets.accept`, `task_notifications.create/update/delete`, `executors.register/heartbeat/drain/unregister`, `scheduler.pause/resume/run_once`, `task_views.create/update/delete`, `task_views.share.plan`, `task_views.share.start`, `task_views.share.revoke`. Plan 24 §9.2 owns semantics and module files; every one is a POST command-envelope use case (plan 10 §8.7). Attestation/review/decision/exception/handoff commands append typed evidence and never set readiness or acceptance directly; `reverse_transition` is a registered optimistic compensating transition with exact prior/new versions and a receipt, while `reopen` creates a new work-item version and never reopens a terminal attempt. `task_offers.accept` is the sole public execution-admission command: it CAS-checks the offer/readiness and invokes the single internal transaction that creates the sealed packet/attempt/lease set atomically. Attempt lifecycle commands require that fence, packet acceptance is fenced at a safe Turn boundary, and notification subscription changes are direct expected-version commands. `work_items.assign_set` is one bounded all-or-none owner-shard transaction with plan/item expected versions and per-item receipts. No task command creates advisory `WorkClaimV1`. Task-view sharing uses the same classification/redaction/expiry plan, confirmed start, and grant revocation protocol as other protected saved views; it preserves the complete protected `TraceQueryV1` (including its scope), projection/group/layout, snapshot/version/watermark, and never copies result rows or invents a second selector. | +| API tokens | `auth.tokens.create`, `auth.tokens.revoke`. Audited commands mint and revoke the scoped/TTL/revocable tokens of plan 17 §18.2; creation returns the secret exactly once through the secure flow, storage keeps only the hash and token ID, revocation declares stream/operation implications, and the per-launch bootstrap bearer (plan 10 §10.2) may execute only `auth.tokens.create` for the initial admin-class token. Token listing is the owner-only read use case above, never a mutation command. | +| Exports | `exports.create`, `exports.cancel`, `exports.delete`. Create freezes query/access/redaction, stages parts under profile export root, and publishes only after final manifest hash. | +| Lab promotion | `labs.fixtures.promote`. Requires sanitized redacted payload, secret scan receipt, exact source manifest, explicit confirmation, and repository-write capability outside lab runtime. | +| Code edits | `code.move_symbol.commit`. It consumes the digest/version from the separate read-shaped `code.move_symbol.inspect`, requires repository/worktree grant and typed confirmation, revalidates both endpoints, performs the destination-first write with source recovery receipt, schedules reindex, and never rewrites callers implicitly. | + +V1 writable dashboard actions not represented by a row above block V1 retirement. PR 3's generated inventory and the application registry jointly enforce this: each mutation has exactly one V2 use case or an explicit retired-with-replacement decision. + +Scope-sensitive command rules are exhaustive and fixture-locked: + +- Create/import operations for facts, skills, policies, automations, saved investigations, and annotations require explicit `DeclaredScope`; there is no “current project” fallback. Autonomous curation candidates derive scope from sealed evidence and policy rather than a public proposal command. +- Updates, archives, restores, and deletes resolve the canonical owner from the target entity and reject a conflicting request scope before validation or execution; autonomous curation has no item approval/apply/rollback commands. +- Cross-project reuse creates evidence relations from the original owner. It never copies a profile fact/skill/policy into a project shard or promotes project state to profile scope implicitly. +- All-scope reads may combine profile-owned and project-owned rows, but each result and command capability retains `owner`, `declared_scope`, privacy domain, and authorization state. +- Moving ownership is a named migration workflow with source/target versions, conflict checks, copy/delete receipts, rollback boundary, and no in-place owner-field edit. + +## 11. Orchestration Rules for Key Product Flows + +### 11.1 Brain and graph-of-graphs + +`brain.overview.get` captures one authorized scope and vector watermark, then requests bounded rollups, health, active-workflow summaries, feedback outcomes, and a focal lens.

Follow-agent retains collaborator and delivery context through bounded relation traversal; it does not filter away parent/subagent causation anchors. + +### 11.3 Hint evaluation and injection + +This flow implements the `HookApplicationPort` fixed by `07-hooks-crate.md`; hooks normalize/render/acknowledge, capture owns spool/fsync/journal durability, and this application composition owns the pinned evaluation. + +1. Authorize host/session/project snapshot access and load immutable tool-catalog, policy, memory, skill, prior-state, and Git evidence refs. +2. Execute policy with explicit effective time, budget, and vector watermark. + Coordination candidate facts contain only unexpired evidence-bearing overlap claims and safe summaries; policy may return at most one coordination hint after pair/work-claim dedupe, cooldown, acknowledgement, and suppression. +3. If live hook mode, transactionally record evaluation and accepted hint-state proposal in the activity owner before returning payload when deadline permits. +4. Hook adapter renders the returned bytes and reports delivery success/failure as a new event. Application never claims emitted/adopted before that evidence. +5. Outcome projector/application records terminal observed/unobserved/unresolvable, missed capability, and human correction with evidence and correct denominator. + +### 11.4 Remote Git reconciliation + +Live refresh is a command because it performs network I/O and appends new evidence, although it cannot mutate GitHub. Local semantic queries remain reads. `delivery.reconcile` joins them only after confirming repository, base/head, merge base, changed-file digest/cap, fetched-at, and local generation. Drift returns both alternatives and an action; application does not silently prefer GitHub or TraceDecay. + +### 11.5 Export + +`exports.create` authorizes requested fields/payload/sensitivity, captures a frozen query/access/redaction snapshot, creates a durable job, and returns immediately. A worker streams query frames into a contained staging sink, checks limits/hashes, writes final manifest, fsyncs, and atomically publishes. Failure/cancel leaves no completed manifest or downloadable partial. Export status preserves searched/skipped/stale/unavailable/incompatible/locked/redacted coverage and reasoning exclusions. + +### 11.6 Evolution Studio and autonomous curation boundary + +Inspection/simulation are lab reads and never gates live progress. The application curation worker consumes policy decisions continuously, revalidates exact candidate/version/evidence/validation/config/privacy/ownership state transactionally, and autonomously creates/updates/supersedes/archives/quarantines/materializes eligible owned facts, memories, and skills. It monitors staged outcomes and automatically revises/recovers when thresholds fire. No `approve`, `reject`, `preview`, `apply`, or user-triggered `rollback` command exists for a curation item; operators configure policy, inspect history, pause/resume/run-now, pin/protect/exclude, or submit feedback. + +## 12.

Plan 18 owns the sanitizer/taint types and privacy workflows; API extraction/output may map eligible wrappers but cannot classify content or invent a weaker “safe string.” + +- Axum handlers depend on `tracedecay-application` use cases and generated catalog bindings. They contain no SQL, shard selection, ranking, policy, Git/GitHub, source ingest, migration, command ownership, or dashboard business logic. +- HTTP does not define a second domain model. Rust request/response schemas reference domain/application types or explicit transport wrappers whose lossless mapping is fixture-tested. +- Task list/query/context and saved-board bodies use the one domain `TraceQueryV1` plus `ScopeSelectorV2`; convenience routes compile to the same canonical request/digest and cannot define `TaskQueryV1`, `TaskContextSelectorV1`, or a board-filter DSL. +- `POST` carries all text queries, saved content, policy inputs, exports, and mutations. URLs contain only nonsensitive enum filters, bounded time/number parameters, opaque IDs, and authenticated cursors/subscription IDs. +- A partial application result is a successful typed response with `!coverage.is_complete()`; it is not transformed into an empty success or generic server error. +- Every mutation routes to one application `execute` command with catalog-owned `ExecutionModeV2`, idempotency, expected version, audit, and optional durable workflow. Confirmed destructive operations use separately named preflight and start/cutover/retire commands; there is no transport-generic preview/apply mode. An HTTP retry cannot create a second semantic effect. +- SSE begins from one frozen application snapshot, then maps query-owned ordered deltas/progress/gap/resync events.

SSE/subscriptions project those journal sequences after commit; HTTP acceptance, outbox/notifier delivery, or an SSE event can never create or acknowledge domain truth independently. +- Browser auth, CSRF, Host/Origin checks, CSP, export containment, and body/decompression limits are mandatory even on loopback. No capability is unauthenticated merely because it binds localhost. +- OpenAPI operation identity comes from `tracedecay-tool-catalog` `BindingId`/`UseCaseId`. The catalog is the registry of record; plan 17's contract IR is its frozen public projection and the single generation source (Section 11). Generated client drift and missing/duplicate route bindings fail CI. +- CLI and MCP do not call HTTP by requirement and do not depend on this crate. Their adapters call application in-process or through daemon composition; parity tests compare typed semantics before CLI/markdown rendering. +- V1 routes/tools exist only inside the bounded migration/shadow harness.

Goals + +- Expose every V2 read, command, lab, export, health, and subscription required by the master plan through bounded, versioned routes. +- Make `GET /sessions` and `GET /messages` completely enumerable for sanitized native rows without a text predicate, using authenticated stable cursors and a captured watermark. +- Make Brain, graph-of-graphs, Universal Explorer, Causal Loom, domain workspaces, Observatory, Costs, all replay labs, and Evolution Studio possible without dashboard-side SQL or private endpoints. +- Generate one checked-in OpenAPI document and TypeScript client that preserve IDs, enums, errors, coverage, cursors, replay fidelity, command receipts, and SSE payload schemas. +- Resume live streams after ordinary disconnects, expose gaps and required resync, coalesce only idempotent updates, and terminate slow clients without silent loss. +- Prevent DNS rebinding, cross-origin browser calls, CSRF, token leakage, path traversal, unsafe exports, content sniffing, framing, and sensitive URL/history/log leakage. +- Preserve identical query/command semantics across HTTP, CLI JSON, MCP JSON, dashboard client, export, and SSE snapshot. +- Provide explicit removal gates for V1 routes, response handles, plugin gateways, and direct dashboard APIs. + +## 3. Non-Goals + +- No GraphQL primary surface, WebSocket requirement, hosted service, multi-tenant identity server, remote libSQL gateway, or arbitrary network bind in the first V2 default. +- No HTML/dashboard component implementation beyond secure SPA/static delivery, bootstrap, history fallback, and asset headers. +- No application authorization rules, query planning, policy evaluation, command transaction, export sink, migration runner, or subscription semantics duplicated in handlers. +- No arbitrary client-supplied filesystem path, shell command, SQL/FTS fragment, renderer code, GitHub mutation, or provider credential over HTTP. +- No event-source query text in the SSE URL. Sensitive subscription/query bodies are posted once and referenced by opaque ID. +- No hidden chain-of-thought API. Only authorized retained provider-exposed reasoning artifacts and coverage markers are representable. +- Internal migration renderers need not preserve every V1 presentation byte. Typed semantics and checked parity receipts are authoritative; no old renderer is a live post-cutover surface. + +## 4. Incoming-Master and V1 Inputs + +### 4.1 Master and incoming changes verified on 2026-07-10 + +The normative publication snapshot is [master §2.6](../2026-07-09-tracedecay-brain-rewrite.md#26-current-master-accepted-changes) plus [plan 13](13-research-provenance-and-context-anchors.md). Regenerate contracts before every API slice; fact ranking, exact analytics, restart-safe applied-manifest retirement, and operator-only split-store consolidation are accepted-base behavior, not autonomous curation. + +| Change | API consequence | +|---|---| +| Merged PR #405 legacy identity adoption | Scope/project routes return one adopted canonical ID with legacy aliases as provenance. Migration/health responses expose ambiguity and receipts without leaking raw sensitive locators. | +| Merged PR #412 safe daemon drain during upgrades | Operation/daemon/update responses expose lease epoch, accepting/draining/stopped state, in-flight counts, progress, last durable receipt, recovery/takeover, and safe retry. SSE cannot collapse drain or terminal transitions. | +| PR #407 Hermes user-profile consolidation | No Hermes profile route or compatibility store is introduced. Hermes/curator/reflector/skill-writer actors appear through normal workflow/agent/automation/knowledge APIs in the active profile. | +| Merged PR #410 message-query dedupe/classification | Message/session/search/export schemas use domain `MessageOrigin`/`MessageView`, plus `representative_for`, rule/version, suppression count, and native expansion cursor. V2 `NativeRows` completely enumerates sanitized rows and preserves retained non-secret structure/semantics. | +| Merged PR #411 foreign-installation doctor severity | Doctor schemas expose `severity`, observed owner, remediation authority, evidence, and legal actions; foreign/unknown ownership cannot serialize an apply/update action. | +| Merged PR #414 `tracedecay_move_symbol` | Preserve V1 dry-run evidence while generating distinct V2 `code.move_symbol.inspect` (read-shaped) and confirmed `code.move_symbol.commit` bindings with impact evidence, snapshot/version, applied imports, recovery/reindex operation, and no implicit caller rewrite. | +| Merged PR #415 release integrity | Generated OpenAPI/SDK/dashboard artifacts and conformance fixtures require an allowlisted release manifest and tracked-ignored-file guard. | +| Merged PRs #413/#416/#418 releases v0.0.46/v0.0.47/v0.0.48 | Regenerate server/protocol/catalog/OpenAPI/compatibility fixtures from accepted master; no behavior depends on release-PR layout or implies the planning host upgraded from installed 0.0.47. | +| Merged PR #417 identity-split visibility | Serialize `identity_split` distinctly from absent index, with safe candidates/evidence and legal backup/consolidation preview; never emit an initialize action. | +| Merged PR #425 explicit split-store consolidation (`de3d05dc`, final head `d3bb28b5`) | Generate admin-only inspect/plan/start/status/resume/recover bindings for the accepted workflow: two explicit nonempty source identities, path-plus-file/inode holder/freeze/reservation state, backups, per-table/artifact dispositions, staging/verification/cutover ledger, deterministic confirmation, and exact recovery. No raw store path in URLs; no handler opens/merges SQLite; no Settings auto-start or curation binding. | +| Merged PR #419 race-safe edits | The move-symbol inspect/commit schemas expose exact source/destination identities/versions, same-file/symlink evidence, pre-commit revalidation, and commit/recovery conflict receipts; no generic success hides concurrent drift. | +| Merged PR #420 daemon proxy/hot swap plus #422 catalog refresh | API/MCP problems and capability metadata distinguish safe per-request reconnect from uncertain-write non-replay and compatible generation-scoped `tools.listChanged` versus incompatible new-session refresh; no adapter opens local stores before authority selection. | + +Refresh live master/open PRs before every 24B–24E slice. The OpenAPI source manifest records commit, catalog digest, domain registry digest, application registry digest, and generation tool versions so stale artifacts fail rather than masquerade as current. + +### 4.2 V1 transport seams + +| V1 seam | V2 disposition | +|---|---| +| `src/dashboard/server.rs`, project gateways, plugin routers | Use only under the bounded migration flag and internal parity harness. New V2 router has explicit methods/typed handlers; cutover removes `/api/v1` live resolution and no `ANY` semantic gateway remains. | +| Direct dashboard plugin APIs for Holographic, LCM, Graph, Analytics, Diagnostics, Savings, Settings, Automation | Map one surface/domain at a time to application. V1 behavior inventory in `08-tool-catalog-crate.md` blocks route retirement until all actions have parity or replacement. | +| `src/mcp/server.rs` and handler schemas/renderers | Exercise old schemas/renderers only in migration parity. Current MCP calls application directly; stale names/clients fail with update/restart/current binding and never proxy through V2 HTTP or V1 semantics. | +| CLI parsers/handlers | Build current generated flags/JSON/text adapters over application. Old flags/shapes are internal parity fixtures, not post-cutover aliases; HTTP schemas do not become CLI implementation types. | +| Response handles for renderer truncation | Migration-only V1 rendering may wrap a V2 cursor/export ID, but every research result also carries a stable canonical anchor/retrieval recipe. V2 never uses an ephemeral response handle as pagination, persistence, deep link, or the only way to recover a session/thread/message/subagent/workflow/Git result. | +| Static dashboard/plugin asset serving | V2 serves one SPA with safe history fallback, hashed assets, and CSP. Migration-only redirects disappear at cutover; asset-path misses never return HTML. | + +## 5.

HTTP Envelope, Cursor, Error, and Version Contracts + +### 7.1 Success responses + +```rust +#[derive(Serialize, Deserialize, ToSchema)] +pub struct ApiResponse { + pub data: T, + pub meta: ApiMeta, +} + +#[derive(Serialize, Deserialize, ToSchema)] +pub struct ApiMeta { + pub request_id: RequestId, + pub use_case: UseCaseRef, + pub protocol: ProtocolRef, + pub catalog_snapshot: CatalogSnapshotRefV1, + pub resolved_scope: ScopeResolutionV2, + pub snapshot: Option, + pub coverage: CoverageReportV1, + pub freshness: FreshnessReport, + pub redactions: RedactionReport, + pub retention: EvidenceRetentionWatermark, + pub limits: AppliedLimits, + pub warnings: Vec, +} +``` + +`CoverageReportV1` is plan 01's canonical shared coverage type. The mapper is exhaustive over `ApplicationResponse`. Compile tests fail if application adds metadata without an API disposition. `!coverage.is_complete()` remains HTTP 200 when useful data exists. An application top-level error maps to a problem response; a partial shard failure already represented in coverage does not become 500. + +List responses use the single `CursorPage` envelope defined once in plan 17's contract IR (plan 17 §13.1) — `{ items, next_cursor, truncation, count_semantics, ordering }` — and serialized here unchanged; plan 21's CLI/MCP pages are the same type, restated in neither plan. + +Cursor strings are authenticated, opaque, URL-safe, size-limited to 8 KiB, and never decoded client-side; they encode exactly the domain `CursorClaimsV1` binding set (plan 01, codec owned by plan 05): query fingerprint, caller/access digest, canonical scope digest, profile-catalog generation, schema/ranking/index versions, frozen watermarks and per-shard positions, sort cutoff, temporal mode/cutoff, intent-profile version, partial-shard dispositions, and expiry. Interactive cursors use plan-20 `query.cursor.interactive_ttl` (default 15 minutes); export/bulk continuations last their catalog-declared job lifetime. Cursor and SSE event-ID authentication uses the persisted profile-local HMAC key set of plan 17 §13.1 (key ID plus rotation), so a server restart does not invalidate otherwise-valid cursors. Frozen snapshots referenced by outstanding cursors/subscriptions are pinned against GC/compaction/projection retirement for the cursor's lifetime by the store/query retention contract (plans 02/05); a pin that cannot be honored fails with a typed `RestartPagination` reason, never silently different data. A cursor mismatch/expiry returns typed restart instructions. + +### 7.2 Errors + +Errors use `application/problem+json` and stable machine fields: + +```rust +pub struct ApiProblem { + pub problem_type: ProblemType, + pub title: CatalogSafeText, + pub status: u16, + pub code: ApplicationErrorCode, + pub detail: Option, + pub instance: RequestId, + pub retry: RetryDirective, + pub current_version: Option, + pub restart: Option, + pub current_binding: Option, + pub candidates: Vec, + pub invalid: Vec, + pub operation: Option, +} +``` + +This is the same `ApiProblem` generated for plan 17's SDKs and consumed by plan 11. `ApplicationErrorCode`, `RetryDirective`, `RestartDirective`, scope candidates, version, binding, invalid-field, and operation semantics come from application/domain contracts. HTTP supplies only RFC 9457 fields and status; SDKs/transports do not define an `ApiErrorCode` fork or infer recovery from status. Plan 21's `SurfaceProblemV2` is exactly this shared shape plus its exit-class mapping table — same field names, `restart` and `current_binding` included. Stale-client codes are exactly plan 17 §12's contract-IR registry: `client_update_required`, `daemon_restart_required`, and `capability_replaced { current_binding }`. + +Status mapping is fixed: + +| Condition | HTTP status | +|---|---:| +| Invalid schema/filter/cursor syntax | 400 | +| Missing/invalid/expired authentication | 401 | +| Authenticated but scope/payload/effect denied | 403 | +| Canonical opaque entity/operation/job/export/subscription absent | 404 | +| Method mismatch | 405 | +| Query/body/media limits | 413 | +| Unsupported media/schema version | 415 | +| Stale client/binding requiring restart or update (`client_update_required`, `daemon_restart_required`, `capability_replaced`) | 426 | +| Version/idempotency/preview/revalidation or storage-identity split conflict | 409 | +| Expired cursor/preview/subscription replay | 410 | +| Validation with field details | 422 | +| Request rate/concurrency limit | 429 | +| Deadline exceeded | 504 | +| All selected shards unavailable or internal invariant | 503/500 according to typed error | + +Problem `detail` never reflects raw parser input, query literal, filesystem path, token, provider payload, or secret. Server logs record request ID, operation/use-case ID, safe error code, timing, byte counts, and coverage—not request bodies or sensitive URLs. + +Transport-created reasons—including JSON/schema failures, bounded/truncated MCP parity failures, export errors, static-route errors, and upstream disconnects—must be converted to safe reason enums plus `LogSafeText` before `ApiProblem`. The API cannot wrap `Display` from an arbitrary error. A unique synthetic canary in each request/error field proves it reaches neither problem JSON, headers, logs, traces, response handles, nor SSE notices. + +### 7.3 Versioning and content negotiation + +- All new routes live under `/api/v2`; path version changes only for incompatible transport contracts. +- Request/response bodies are UTF-8 JSON with `Content-Type: application/json`; exports/downloads use declared formats. Operations whose catalog entry declares bulk support also stream the same canonical rows as bounded NDJSON under `Accept: application/x-ndjson`, equal to paged rows at the same frozen watermark (plan 17 §13.3). Request schemas are closed: unknown named body fields are rejected, and forward-compatible request additions travel only in the declared bounded `extensions` slot per plan 17 §6.2 — never silently promoted into query semantics. +- OpenAPI records schema/registry/catalog/application versions. Response `Vary` includes only headers that truly affect representation; no cache varies on bearer token values. +- Immutable public-within-session manifests/bundles may use private ETag revalidation. Payload-bearing, query, lab, message, export-status, and command responses use `Cache-Control: no-store`. + +## 8. Complete HTTP V2 Surface + +Every route is authenticated except the static HTML/assets and one-time bootstrap exchange described in Section 10.

Batch is an API transport multiplexer over existing use cases, not a separate application use case. | + +Scope query parameters are bounded opaque IDs/enums and pagination only. Project search text uses `POST /api/v2/projects/search` so literal text does not enter URLs. Every binding has a catalog-declared default that is inserted as an explicit canonical selector request: Brain/Observatory use `AllAuthorized { profile_id }`; code-local bindings may use `CurrentInvocation`. Handlers never infer cwd, last project, route, or referrer independently. + +Domain `ScopeSelectorV2` and `ScopeResolutionV2` are serialized unchanged. The selector is exactly `version`, nonempty `roots`, `exclude`, `time`, `activity_attribution`, `coverage`, `freshness`, `traversal`, `ambiguity`, and `limits`; canonical/locator targets use `ScopeTargetV2`. Resolution includes `resolution_id`, selector digest/canonical selector, selected/ambiguous/stale/unavailable/quarantined/missing sets, `defaulted_current`, catalog generation, and watermark. A client resubmits the preserved canonical request plus selected candidate once; query/filter/time/message-view bodies are not reconstructed client-side. CLI/MCP/API/SDK/dashboard parity fixtures require identical candidate identity/order, resolution, provenance, and errors. + +Doctor/provider payloads use generated `DoctorFindingView` and `ProviderIntegrationState`. `severity`, `observed_owner`, `remediation_authority`, evidence, legal actions, hook/tool/session coverage, missing pieces, and last verified time are required. An apply/update action for foreign or unknown ownership is unrepresentable in the application view itself (plan 09 §9.1); this serializer adds no second gate and cannot express one, and it never maps `Partial`/`Degraded` to healthy branding. + +### 8.2 Query, Brain, graph, timeline, and inspector + +| Method and path | Contract | +|---|---| +| `POST /api/v2/query` | Generic bounded `TraceQueryV1`. | +| `POST /api/v2/search` | Opinionated universal search with explicit ranking profile. | +| `POST /api/v2/search/benchmark` | Read-only one/two-profile run over the versioned redacted benchmark corpus with per-slice metrics and blockers. | +| `POST /api/v2/entities:batch` | Bounded universal inspector hydration. | +| `POST /api/v2/brain/overview` | All reading path at requested scope/time/snapshot. | +| `POST /api/v2/brain/lens` | One bounded graph-of-graphs lens. | +| `POST /api/v2/brain/clusters/{id}:expand` | Stable aggregate expansion by opaque cluster ID. | +| `POST /api/v2/graph/neighborhood` | Evidence-filtered bounded neighborhood. | +| `POST /api/v2/graph/path` | Bounded stable paths. | +| `POST /api/v2/graph/subgraph` | Query-driven bounded subgraph using the same graph query/operator contract. | +| `POST /api/v2/graph/impact` | Evidence-bearing impact. | +| `POST /api/v2/graph/diff` | Frozen graph snapshot/ref/session/policy/time comparison. | +| `POST /api/v2/graph/affected-tests` | Bounded affected tests. | +| `POST /api/v2/timeline/density` | Server-side density/LOD buckets. | +| `POST /api/v2/timeline/events` | Cursor event/Turn/agent lanes. | +| `POST /api/v2/timeline/as-of` | Valid-time and observed-time historical state. | +| `POST /api/v2/timeline/follow-agent` | Agent/subagent/collaborator/delivery lanes. | +| `POST /api/v2/timeline/compare` | Aligned comparison anchors and deltas. | +| `POST /api/v2/activity/events` / `POST /api/v2/activity/facets` | Consequential cross-domain activity and facets over one frozen/live event model; routine-noise counts remain explicit. | + +All graph/timeline inputs require explicit node/edge/event/lane/bucket/page/depth/byte budgets within query hard limits. Federated inputs accept explicit multi-repository/project/worktree/ref scope, preserve each node/edge's repository/snapshot provenance and per-shard freshness/coverage, and reject same-name collapse. The API rejects missing bounds before calling application. Read POST bodies carry the application `ReadRequirementsV1` envelope (consistency, budget, payload policy; plan 09 §7.2) as a top-level `read` object; GET enumerations accept only its bounded enum/watermark forms as query parameters. + +`POST /search` accepts generated exact-token/field, phrase, fuzzy, entity/alias, semantic, graph-neighborhood, and recency profile controls plus origin/kind/provider/session/agent/repository/project/worktree/ref/time filters and grouping/dedupe policy. It returns per-stage candidates/caps/exclusions/versions, final score components, missing features, grouping membership, native expansion, repository/snapshot provenance, coverage, and benchmark-profile ID. “Semantic” is never an implicit default: clients request a versioned evaluated profile, and the server may disable vector contribution when unavailable or regression-gated. The benchmark endpoint includes the named Rspack/Rsbuild/React Router cross-repo disambiguation slice. + +### 8.3 Sessions, messages, turns, agents, and workflows + +| Method and path | Contract | +|---|---| +| `GET /api/v2/sessions` | No-text cursor enumeration with provider/host/time/kind/opaque scope filters. | +| `POST /api/v2/sessions/search` | Text/semantic session search. | +| `GET /api/v2/sessions/{id}` | Summary, participants, goals/workflows, snapshots, coverage. | +| `POST /api/v2/sessions/{id}/replay` | Read-only historical assembly and replay fidelity. | +| `POST /api/v2/threads/{id}/replay` | Read-only thread assembly across its authorized session/Turn lineage. | +| `GET /api/v2/sessions/{id}/context-lineage` | LCM source/summary DAG, compression decisions, payload coverage and source ranges. | +| `GET /api/v2/sessions/{id}/turns` | Bounded first-class Turns. | +| `GET /api/v2/turns/{id}` | Turn hub with authorized linked evidence. | +| `GET /api/v2/messages` | No-text cursor enumeration with domain message view plus provider/time/role/kind filters. | +| `POST /api/v2/messages/search` | Literal/semantic search with the same domain message-view contract. | +| `GET /api/v2/messages/{id}` | Native or representative message view. | +| `GET /api/v2/messages/{id}/native` | Cursor expansion to represented sanitized native rows and source observations.

A client obtains sanitized native rows through that cursor or a second `view=native_rows` request bound to the same snapshot; the API does not invent a combined “both” count. The catalog-declared export default — owned by application/catalog metadata, not by this transport — is the complete sanitized-native enumeration; a caller may explicitly request another `MessageView`, and the manifest declares that projection. + +### 8.4 Domain workspace reads + +These routes are typed profiles over application/query, not separate service implementations: + +| Family | Routes | +|---|---| +| Code | `POST /api/v2/code/search`, `/find-exact-symbol`, `/grep`, `/context`, `/callers`, `/callees`, `/path`, `/impact`, `/affected-tests`, `/test-map`, `/diagnose`, `/move-symbol:inspect`; `GET /api/v2/code/files`, `/health`, `/diagnostics`. `move-symbol:inspect` is `EffectClass::Read` despite its protected request body. | +| Git/delivery | `GET /api/v2/git/branches`; `POST /api/v2/git/branch-search`, `/branch-diff`, `/pr-context`, `/changelog`, `/commit-context`, `/sessions-for`, `/workflows-for`, `/reconcile`; `GET /api/v2/delivery/repositories/{id}`, `/pulls/{id}`, `/checks`, `/reviews`, `/releases`. | +| Knowledge | `GET /api/v2/knowledge/facts`, `/facts/{id}`, `/entities`, `/entities/{id}`, `/trust-history`, `/conflicts`, `/retrievals`, `/feedback`; `POST /api/v2/knowledge/search`, `/deletion-impact`. | +| Automation | `GET /api/v2/automation/jobs`, `/jobs/{id}`, `/scheduler`, `/runs`, `/runs/{id}`, `/runs/{id}/artifacts`, `/candidates`, `/candidates/{id}`, `/decisions`, `/decisions/{id}`, `/effects`, `/effects/{id}`, `/outcomes`, `/outcomes/{id}`, `/recoveries`, `/recoveries/{id}`, `/history`, `/skills`, `/skills/{id}`; `POST /api/v2/automation/workflow-graph`. Legacy proposals/approvals/applies are labeled records returned only through history. | +| Research provenance | `GET /api/v2/research/manifests`, `GET /api/v2/research/manifests/{id}`.

Semantics are owned by plan 24 §9.1; offer reads require the authenticated registration and packet reads require the attempt scope. Query/explain/doctor POST bodies carry protected scope/evidence while remaining `EffectClass::Read`; every mutation uses the Section 8.7 command envelope with no `PATCH` route. Catalog capability `task_graph.events` binds to canonical subscription read-model kinds delivered through `POST /api/v2/subscriptions` plus `GET /api/v2/subscriptions/{id}/events`, not a separate `/task-events` stream. | + +Git request/response schemas retain local semantic generation/ref/merge-base/watermark separately from live provider/fetched-at/base/head/changed-file cap/digest.

Field mapping onto the application `CommandEnvelopeV1` is fixed and fixture-tested: application deterministically allocates `command_id`; `idempotency_key` maps to the plan 09 §8.1 reservation key; `scope` maps to declared/canonical scope; `expected_version` is the optimistic aggregate version; and `payload` is the typed command body. A catalog-declared confirmed destructive command has a distinct input type containing its operation-specific `OperationPreflightId` and protected confirmation token.

Attempt lifecycle and packet acceptance require the active fence; packet acceptance also requires the exact prior packet and safe Turn boundary. Task-notification mutations never create implicit subscriptions. `WorkClaimV1` remains only under coordination reads/events; no task command is named “claim.” + +Anchor operation IDs are exactly `retrieval_anchors.metadata_batch_get`, `retrieval_anchors.resolve`, and `retrieval_recipes.execute`, bound only to `POST /api/v2/retrieval-anchors:metadata-batch`, `POST /api/v2/retrieval-anchors:resolve`, and `POST /api/v2/retrieval-recipes:execute`. Research-manifest operations remain `research.manifests.list`, `research.manifests.get`, and `research.manifests.create_version`. Plan 17 generates SDK methods from these OpenAPI operations; no SDK resolves a `ResearchAnchorId`, treats safe metadata as payload authority, invents a research-specific evidence-anchor type, or bypasses the generic resolver. + +Search-evaluation mutation routes bind one-to-one to `retrieval.corpus_versions.create/freeze`, `retrieval.qrel_versions.create/freeze`, `retrieval.candidate_pools.create`, `retrieval.judgments.record/supersede`, `retrieval.adjudications.record`, `retrieval.evaluation_runs.run/cancel`, `retrieval.evaluation_reports.publish`, `retrieval.fixtures.promote`, and `retrieval.profiles.publish/activate`. They use the ordinary command envelope and immutable/superseding artifacts: no route edits a frozen corpus/qrel, rewrites a prior judgment, hides source labels during adjudication, publishes private report content, promotes an unscanned fixture, or changes an in-flight query's profile. + +The storage-consolidation routes bind only plan 09's operator workflow. `inspect/plan/status` are read-shaped application results; POST is used for inspect/plan because protected source references do not belong in URLs. `start/resume/recover` require administrative capability, exact source IDs, durable operation state, deterministic confirmation where applicable, and fail-closed path-plus-file/inode holder/lease/write-reservation evidence. V1 `preview/apply` names exist only in the compatibility adapter/inventory. These bindings are absent from curation credentials and cannot be invoked by task executors, scheduler, dashboard auto-save, or a generic Settings patch. + +The explicit saved-view/collection/annotation and export action routes in Section 8.6 are the sole HTTP bindings for those commands; duplicate `/commands/**` aliases are not added. They use the same generated application command envelope, idempotency, expected version, direct validation or operation-specific share plan/start contract, and audit. Scope-sensitive create bodies require `declared_scope`; existing-target bodies carry the opaque target and the application resolves its canonical owner. No current V1 dashboard mutation may bypass this inventory. + +Coordination commands carry application preconditions (plan 09 §10) that this API validates as transport shape and surfaces unchanged: an unexpired presence/overlap claim, stable research anchor, explicit target agent/capability, disclosed-summary/effect digest, idempotency key, and disclosure-safe summary. `message` and `handoff` record attempted delivery separately from target receipt; `ack` requires authorized target evidence; `suppress` is scoped to agent/pair/work-claim plus expiry. The API accepts no arbitrary provider address, hidden prompt payload, free-form tool invocation, or client assertion that delivery succeeded. + +## 9. SSE Snapshot, Delta, Resume, Gap, and Backpressure + +### 9.1 Subscription creation + +Clients post the sensitive query/read-model body to `/subscriptions`. Application authorizes it, captures a frozen snapshot and access digest, and returns: + +```rust +pub struct SubscriptionCreated { + pub subscription_id: SubscriptionId, + pub expires_at: UtcMicros, + pub snapshot_watermark: VectorWatermark, + pub replay_retention: Duration, + pub stream_path: SafeRelativePath, +} +``` + +The subscription ID is 256-bit random plus server-side digest lookup, bound to authenticated session/principal, access digest, use case, query fingerprint, schema/ranking/catalog versions, expiry, and snapshot. It contains no query plaintext. Re-authentication with a different access digest invalidates it. + +### 9.2 Wire events + +```rust +#[serde(tag = "type", content = "payload")] +pub enum ApiStreamEvent { + Snapshot(SubscriptionSnapshot), + Delta { watermark: VectorWatermark, changes: Vec }, + Operation(OperationProgress), + Projection(ProjectionProgress), + Coverage(CoverageReportV1), + Gap { expected: VectorWatermark, available_from: VectorWatermark }, + ResyncRequired { reason: ResyncReason, restart: RestartDirective }, + ServerNotice { code: NoticeCode, retry_after_ms: Option }, +} +``` + +`SubscriptionSnapshot` and `SubscriptionDelta` are generated tagged unions for the authorized canonical `TraceQueryV1` read-model kind. Task deltas include the causing canonical `task_graph_events` sequence range plus projector watermark; they never expose a parallel task event identifier or accept writes. `OperationProgress` covers command, job, workflow, export, migration, and automation state with stable operation/event/audit refs and an explicit terminal disposition. A command apply returns HTTP `200` when its semantic effect is complete and `202` with the same `CommandReceipt` when a durable operation/workflow/job remains; clients follow the operation event and can recover through `GET /operations/{id}`, never infer completion from transport acceptance. + +- The first semantic event is `snapshot` unless a valid `Last-Event-ID` resumes after it. +- Every semantic event has `id: `, `event: `, one canonical JSON `data:` payload, and no server-generated retry that exceeds client policy. +- Heartbeat is an SSE comment every 15 seconds; it consumes no sequence and requires no client state change. +- Event IDs bind subscription, stream sequence, vector watermark, schema/projector versions, expiry, and access digest through canonical CBOR + HMAC-SHA256. Tamper/mismatch returns 409/410 before stream start. +- Replay retention defaults to five minutes or 10,000 semantic events per subscription, bounded globally. Expiry/gap emits `resync_required` when possible, then closes; reconnect creates a new snapshot. +- Duplicate/out-of-order source changes are suppressed by query semantics before wire mapping. Client still applies deltas idempotently by event ID/entity stable key. + +### 9.3 Backpressure and disconnects + +- Each connection has capacity 256 semantic frames and 2 MiB serialized queued bytes; per-principal and global connection caps are explicit configuration. +- Repeated upserts for one entity may coalesce to the newest upsert only when no remove, coverage, gap, progress terminal, or ordering boundary lies between them. +- Coverage, remove, gap, resync, operation/workflow terminal, privacy, and command/projection failure events never coalesce away. +- At soft pressure, coalesce eligible updates and emit safe metrics. At hard pressure, enqueue one `resync_required { slow_consumer }` if possible and close. Never discard and continue as if complete. +- Disconnect cancels the transport stream and releases API buffers; application/query subscription retention owns finite replay, not an Axum task leak. +- Browser/client reconnects with capped exponential backoff and `Last-Event-ID`. `401/403` stops retry; `409/410` creates a new subscription/snapshot; `429/503` honors bounded retry advice. +- SSE headers include `Content-Type: text/event-stream`, `Cache-Control: no-store`, `X-Accel-Buffering: no`, and security headers. Compression/proxy buffering is disabled for the event stream. + +## 10. Loopback Authentication, CSRF, Host/Origin, CSP, and Request Security + +### 10.1 Bind and Host policy + +- Default listeners bind `127.0.0.1` and `[::1]` only. Startup fails rather than silently falling back to wildcard. +- Non-loopback bind requires explicit protected-mode configuration, TLS, an architecture/security review, and is outside first-default support. +- Accept only exact configured authorities: `127.0.0.1:`, `[::1]:`, and `localhost:` when enabled. Reject missing, malformed, multiple, userinfo, trailing-dot, wildcard, unexpected port, and untrusted `Forwarded`/`X-Forwarded-*` headers. +- Absolute-form request targets and proxy mode are rejected by default, preventing DNS-rebinding/proxy confusion. +- A user-owned Unix-domain socket listener is a first-class transport built by this crate (plan 17 §18.1 prefers it for local nonbrowser clients; plan 17 §24 owns its conformance suite). The socket directory and file are owner-only (`0700`/`0600`), peer credentials (`SO_PEERCRED`/`getpeereid`) must match the profile owner, and application token authentication still applies. Cookie, CSRF, and Host/Origin rules are HTTP-listener browser rules and neither apply to nor weaken over the socket; browser sessions are not accepted on it. + +### 10.2 Launch, browser session, and bearer authentication + +1. Server generates a 256-bit per-launch secret from the OS CSPRNG and never logs it. +2. Static HTML receives one single-use, 60-second bootstrap nonce in a nonce-authorized bootstrap script/meta block. It is not placed in URL, referer, local storage, analytics, logs, or cache. +3. Browser posts the nonce to `POST /api/v2/auth/session` under strict Host/Origin. Server consumes it and creates an HttpOnly, SameSite=Strict, Path `/api/v2` session cookie; `Secure` is required whenever HTTPS is used and loopback HTTP is the only permitted exception. +4. Response returns a separate CSRF token held in page memory. Every cookie-authenticated state-changing request supplies `X-TraceDecay-CSRF`; token is session/method-family bound, rotates on login/privilege change, and compares constant-time. +5. The per-launch `Authorization: Bearer` token obtained from the owner-only (`0600`) runtime endpoint/file managed by composition is a bootstrap credential, not the operating credential: its only permitted operation is `auth.tokens.create` (plan 09 §10), which mints the initial admin-class entry in plan 17 §18.2's token registry. CLI/MCP/daemon clients then authenticate with scoped, TTL-bounded, revocable registry tokens. No token appears in a query parameter or command output. +6. Sessions expire at process exit and after bounded idle/absolute lifetimes; logout/restart revokes them. Authentication failures reveal no token validity detail. + +All cookie-authenticated unsafe methods require valid CSRF, exact Origin, `Sec-Fetch-Site: same-origin` when supplied, JSON content type, and authenticated principal. Bearer clients do not require CSRF but still cannot bypass Host, method, schema, authorization, or limits. CORS is disabled by default; no wildcard origin or credentials response exists. + +### 10.3 Browser/security headers + +HTML policy: + +```text +default-src 'none'; script-src 'self' 'nonce-'; style-src 'self'; +img-src 'self' data: blob:; font-src 'self'; connect-src 'self'; worker-src 'self' blob:; +object-src 'none'; base-uri 'none'; form-action 'none'; frame-ancestors 'none' +``` + +No `unsafe-inline` or `unsafe-eval`. Bootstrap nonce authorizes only the minimal generated bootstrap block. All responses set `X-Content-Type-Options: nosniff`, `Referrer-Policy: no-referrer`, `Cross-Origin-Opener-Policy: same-origin`, and frame denial through CSP; HTML additionally uses `Cache-Control: no-store`. Hashed assets use immutable private caching and correct MIME. Source maps are off by default in release and never expose embedded user data. + +### 10.4 Limits and timeouts + +- Default JSON body 1 MiB; explicit lab/query bodies 4 MiB; fixture-promotion manifest 16 MiB after authorization; no generic unlimited override. +- Reject compressed request bodies by default. If later enabled for a declared route, enforce compressed and decompressed limits plus ratio/time ceilings before JSON parsing. +- Header section 32 KiB, URI 8 KiB, cursor 8 KiB, 100 query parameters, depth-limited JSON, bounded strings/arrays per schema, and finite numeric validation. +- Route-specific request timeout is less than application deadline; long work returns a job ID instead of holding HTTP open. +- Global/per-principal concurrency limits distinguish reads, expensive queries/labs, commands, exports, and SSE. Queue wait counts toward deadline. +- Cancellation propagates on disconnect/deadline to application/query, but cannot undo a committed command transaction; receipt lookup recovers outcome. + +### 10.5 Export containment + +- HTTP export create accepts format, query/view ID, redaction/payload policy, row/byte limits, expiry, and a display filename hint only. It never accepts a path, URI, device, symlink, or overwrite flag. +- Application/store select the private profile export root, exclusive staging file, permissions, fsync, hash, manifest, and atomic publication. API receives only `ExportId`/authorized byte stream. +- Display filename is Unicode-normalized, strips separators/control/reserved names, length-capped, and always emitted through standards-compliant `Content-Disposition` with a safe ASCII fallback. +- Download sets exact type, length/hash/ETag, `nosniff`, `Content-Disposition: attachment`, `Cache-Control: no-store`, and supports bounded byte range only for immutable completed parts. +- Incomplete/cancelled/expired/redacted-denied exports cannot download. API never reveals the backing filesystem path. + +## 11. OpenAPI and Generated TypeScript Client + +### 11.1 Source and generation + +- Generation authority (single source): plan 17's contract IR is the only source of generated public contract artifacts. Pipeline: domain schemas + application use-case registry + plan 08 capability catalog → canonical contract IR snapshot (`crates/tracedecay-api/contract/tracedecay-contract-ir.v1.json`, owned by plan 17) → generated OpenAPI 3.1 (`crates/tracedecay-api/src/openapi/generated.json`, hosted by plan 10), the review rendering `crates/tracedecay-api/openapi/tracedecay-v2.yaml`, and the public JSON Schemas (`crates/tracedecay-api/schemas/*.schema.json`) → plan 10's Axum adapters conform to the IR-generated document, with utoipa reflection retained as validation only (CI regenerates the utoipa-derived document and fails unless it is semantically identical to the IR-generated artifact) → the generated TypeScript schema core at `packages/tracedecay-client/src/generated/` is produced from the IR-generated OpenAPI and hosted per plan 10, while plan 17 owns SDK packaging and conformance. The capability catalog remains the registry of record for capability/binding identity; the contract IR is its frozen public projection, and no plan or adapter maintains a second route registry. +- The checked-in document uses deterministic key/path/schema ordering and strips nondeterministic build timestamps. +- Operation ID equals the current catalog HTTP `BindingId`; extension fields carry canonical `UseCaseId`, capability ID/version, read/mutate, idempotency, preview, streaming, freshness, privacy, and cost/latency. Old/migration bindings never enter shipped OpenAPI. +- Security schemes describe browser cookie + CSRF header and bearer auth. Every operation declares one valid scheme and required scopes; no accidental anonymous operation. +- The generator validates method/path uniqueness, request/response/error schema mappings, status sets, cursor/page semantics, command headers/body, SSE event union, and catalog parity. +- `packages/tracedecay-client/src/generated/schema.ts` is generated with `openapi-typescript`. Its transport-neutral runtime owns request IDs, problem decoding, cancellation, cursor helpers, and SSE state. `dashboard/packages/api-client` imports it and adds only browser cookie/CSRF/bootstrap handling; it has no generated schema or competing error/event model. +- Generated files carry source commit/catalog/domain/application/OpenAPI digests and are changed only by the generation command. + +Generation command: + +```bash +cargo run -p tracedecay-api --bin generate-openapi -- --check # regenerate from the contract IR; assert utoipa-reflection equality +pnpm --dir packages/tracedecay-client generate +pnpm --dir packages/tracedecay-client test +``` + +Expected in check mode: regenerated OpenAPI and TypeScript bytes exactly match checked-in files; all route/catalog/schema digests agree. + +### 11.2 Client behavior + +- `ApiClient` methods accept typed request plus `AbortSignal`; queries/commands never use untyped JSON maps. +- `ApiResult` preserves `meta`; convenience methods cannot return `data` without exposing meta to the caller. +- `ApiProblemError` preserves code/retry/current-version/restart/current-binding/candidates/invalid/operation fields, while redacting body/token from logs. +- SSE client keeps subscription IDs and `Last-Event-ID` in page memory only; they are session-bound capability material, not a nonsensitive IndexedDB key. It applies deltas idempotently, reports stale/offline/gap, and requests a new snapshot when required. +- Client sends no sensitive query/annotation/saved-view text in URL, analytics, error telemetry, or clipboard links. +- Runtime schema smoke tests feed every checked-in semantic fixture through Rust serialization, OpenAPI validation, generated TypeScript decoding, and reserialization. +- Stable research anchors/recipes round-trip as generated types. Client helpers may follow an opaque page cursor, but saved state, copy links, exports, and recovery APIs reject an ephemeral response handle as their only locator. + +## 12. CLI, MCP, Dashboard, and HTTP Semantic Parity + +The parity harness invokes one application use case through each applicable adapter and compares canonical semantic JSON after removing transport-only request IDs/timing: + +```rust +pub struct TransportSemanticFixture { + pub use_case: UseCaseId, + pub input: CanonicalRequestFixture, + pub expected: CanonicalResponseFixture, + pub bindings: Vec, + pub allowed_presentation_differences: Vec, +} +``` + +Required comparisons: + +- catalog-declared explicit default (`AllAuthorized` for Brain/Observatory, `CurrentInvocation` only where declared); repository/project/worktree/ref identity; same-name candidates/order; one-step retry token; provenance/freshness/partial state; +- entity/row/edge identity, order, facets, aggregates, cursor claims/restart codes, snapshot/watermark, coverage, freshness, redaction, retention, evidence, confidence, ranking explanation; +- native/representative/human-best-effort/direct-user/delegated-agent/tool-result/provider-protocol message views and representative provenance; +- command preview, idempotency, expected/current version, effect/audit/workflow receipt, conflict/retry; +- replay mode/fidelity, digests, substitutions, read-only behavior; +- Git local/live revisions, reconciliation/drift, fallback state; +- error code/retry semantics before CLI exit-code, HTTP status, or MCP markdown rendering; +- SSE initial snapshot equals ordinary HTTP query snapshot at the same watermark; export logical rows equal paged query rows at its frozen watermark. + +MCP markdown and CLI text may differ only in checked presentation fixtures. JSON modes use the typed schema. Handler source is linted to reject store/query/policy imports and direct SQL. V1 aliases exist only in the internal migration harness; current help, hints, catalogs, and live dispatch never advertise or execute them after domain cutover. + +## 13. Static SPA, History Fallback, and Bounded Migration Paths + +- `/` and known V2 product routes serve release HTML; hashed `/assets/*` serves only assets. Missing asset paths return 404, never HTML. +- The authenticated API explorer and docs shell (plan 17 §22) are served by this same static_app under `/docs` with identical CSP/bootstrap/auth rules; its "try" calls use ordinary authenticated `/api/v2` routes, and the fixture-backed sandbox (plan 17 §22.3) is a separate process/profile, never a production route family. +- History fallback recognizes the route manifest generated by the dashboard build. Unknown `/api/*`, dotted paths, traversal, encoded separators, NUL/control characters, and unsupported methods never fall through to SPA. +- While the explicit migration flag is active, legacy `?tab=` and plugin URLs may issue a safe same-origin redirect to equivalent V2 state using opaque IDs. After cutover, stale paths return `client_update_required` — or `capability_replaced` with the current binding — plus the current route/update action, and never silently redirect or revive a stale name. +- Direct reload, base path, back/forward, embedded asset, stale asset hash, CSP nonce, service-worker absence, and host-wrapped dashboard are contract-tested. +- Old and new shells may coexist only behind explicit migration feature state until every V1 view/action parity row passes. Cutover removes old live route/name resolution atomically; retained plugin assets, if still needed for rollback evidence, are not served as a fallback. + +## 14.

Enable read routes per domain in shadow/explicit-client mode and compare typed semantics against application/V1 fixtures. +3. Enable V2 dashboard client for one read-only vertical slice while the legacy shell remains available only under the bounded migration flag. +4. Enable each command's catalog-declared execution mode per domain only after application parity/recovery receipts and API security tests pass; never stage a universal preview/apply layer. +5. Enable SSE after snapshot parity, finite replay, gap/backpressure, and reconnect E2E pass under load. +6. Switch CLI/MCP bindings per domain to the current generated application contract; remove old names from live help/hints/catalog at the same cutover. +7. During bounded migration only, an operator rollback may restore the V1 owner from its receipt. After V2 default, rollback uses a prior compatible V2 artifact/data snapshot, closes streams with typed restart, and never revives stale clients/names. +8. At each domain cutover, revoke old live API/plugin/tool bindings. Stale clients receive the plan 17 §12 stale-client codes — `client_update_required`, `daemon_restart_required`, or `capability_replaced` with the current binding — plus restart/update/current operation/path; current help/hints/catalog never advertise old names. +9.

Every aggregate states exact versus sampled counts, denominator, hidden count, coverage, watermark, and aggregation/layout version. Unknown is never displayed as zero; inferred is never displayed as observed; correlation is never styled as causation. +5. Sanitized native records are never silently discarded. Merged PR #410's copied-subagent-prompt dedupe and domain `MessageOrigin`/`MessageView` become explicit UI modes with representative and hidden-copy counts plus source provenance; protected plaintext, if retained, is available only through the separate elevated quarantine workflow. +6. Canonical V2 read models and commands are the application/API responsibility. Feature modules do not join raw endpoints, synthesize source-of-truth counts, interpret tool schemas, or write stores directly. +7. All replay labs are read-only by default. Exact, recorded-result, and current best-effort are distinct, persistent labels; unavailable historical inputs are shown as unavailable, not substituted silently. +8. The app is local-only and loopback-secured by default. Sensitive literals never enter URLs, browser history, analytics, SSE subscription URLs, cache keys persisted in clear text, clipboard links, or catalog rows. +9. Accessibility, mobile behavior, table parity, partial/offline behavior, deterministic export, and visual QA are acceptance gates in every feature PR. PR 32 audits and polishes them; it does not introduce them for the first time. +10. Existing plugins keep their complete read and write behavior until the owning V2 workspace passes behavior/action parity. There is no blanket read-only transition. +11. No decorative dashboard-card grid, fake metric, gratuitous badge/pill, particle field, 3D graph, perpetual force animation, or color-only evidence encoding is allowed. Use open canvases, rails, lists, matrices, tables, timelines, and one clear focal artifact. +12. The shipped UI is code-native. Image-generated concepts are implementation references, not rasterized application screens. +13. Doctor/provider/daemon branding is evidence-driven: foreign-owned packages are informational, partial integrations are labeled partial, and upgrade completion requires a durable drain/recovery receipt rather than a green icon inferred from process exit. + +The normative publication snapshot is [master §2.6](../2026-07-09-tracedecay-brain-rewrite.md#26-current-master-accepted-changes) plus [plan 13](13-research-provenance-and-context-anchors.md). The UI inventory also exposes untracked branch/session variants, bounded consolidation progress, lifecycle deferrals, registry-healing decisions, FTS maintenance health, graph-checkpoint safety, and restart-safe applied-manifest retirement as typed evidence rather than hidden repair. + +## 2. Product model and design direction + +The product is an evidence workbench for one interconnected system: + +```text +profile + ├─ projects / repositories / worktrees / refs / commits / PRs / releases + ├─ threads / sessions / Turns / messages / visible reasoning / context / goals + ├─ actors / agents / subagents / delegations / handoffs / workflows + ├─ tools / code symbols / files / patches / diagnostics / tests / impact + ├─ facts / decisions / contradictions / retrieval / trust / memory versions + └─ schedules / curator-reflector-skill-writer runs / candidates / autonomy decisions / effects / recoveries / skills / outcomes + +identity + time + scope + evidence + provenance + coverage connect every lane +``` + +The interface has one visual thesis: **a quiet investigative instrument with a living but stable map**.

The `privacy` slug displays as "Privacy & Secret Safety Lab" and supersedes the retired `secret-safety` route name; plan 23's temporal "Search Lab" content is folded into the Search Quality Lab, not a separate lab. Hint Lab includes deterministic and incremental-scout replay, Search Quality includes temporal session/LCM retrieval, and Orchestration replays plan/task/executor/context/lease decisions at `/playgrounds/orchestration` (the only route spelling) against plan 10 §8.5's generated `POST /api/v2/labs/orchestration:replay` endpoint. Evolution has a named route because it is both a lab and a product workspace. + +Route changes do not clear scope/time/query/selection unless the destination cannot represent the selected entity. In that case, the selection stays pinned in the inspector and the main view explains the unsupported relation. Browser back/forward restores complete committed investigation states, not only route names. + +Superseded route names are recorded here so no ledger dangles: the master plan's `/threads` and bare `/turns` list views are served by `/sessions` and the `threads`/`turns` lenses; `/agents/nearby` became `/coordination`; `/proposals` is retired by the no-approval-queue autonomy model and its content lives under `/evolution`; `/secret-safety` became `/playgrounds/privacy`. Bounded migration-only mappings live in `migration-paths.ts` and disappear at cutover; no current route metadata advertises the stale names. + +## 4.

This mapping is generated/fixture-tested; the fixture asserts that the route `:lens` slug list, the `view.graphLens` union members, and the generated application enum stay identical (ten entries each) so a lens can never be routable but URL-unrepresentable. Feature code never title-cases or guesses an enum. + +Selection, comparison, and inspector semantics: + +- Every selection kind the inspector supports (section 9.2) is a `SelectionV1` variant, so relation, aggregate, time-range, and comparison selections are URL-encodable, shareable, and restorable like entity selections. Selections serialize with sorted keys and default elision and carry only opaque IDs. +- Period comparison lives in `time.compare` as explicit A/B ranges; entity/aggregate/path/relation/time-range pair comparison is a `comparison` selection. The section 9.1 compare toggle populates exactly one of these two homes; there is no third comparison shape. +- `InspectorTabV1` is owned here; plan 24 cites it. Plan 24 §12.6's eleven task-inspector tabs map onto the union by a checked table: Overview/specification/constraints→`specification` (`summary` remains the universal landing tab), Dependencies/gates/critical path→`dependencies`, Acceptance/evaluations/exceptions→`acceptance`, Assignments/eligible executors/routing→`assignments`, Attempts/retries/cancellation→`attempts`, Context packets/omissions→`packets`, Decisions/handoffs/artifacts/outcomes→`decisions`, Thread/session/Turn/agent/goal/tool evidence→`evidence`, Code/Git/delivery impact→`impact`, Costs/budgets→`costs`, Audit/provenance/anchors→`audit`. The attempt inspector reuses the same union. Workspaces cannot invent tab values outside this union; non-Work routes ignore Work extension tabs with an explicit "tab unavailable here" state, never a silent reset. +- The `audit`/`evidence` tabs for plans, documents, initiatives, work items, attempts, agents, and subagents expose versioned research manifests from plan 13: immutable manifest-entry `ResearchAnchorId`, nonempty canonical `RetrievalAnchorId` links, contributor/session/role/output attribution, unresolved attribution gaps, source/catalog/Git watermarks, drift, coverage, redaction state, and retrieval recipe. Selecting an entry resolves evidence only through its canonical retrieval anchors; the UI never treats a research entry ID, response handle, URL, or search rank as payload authority. "Copy evidence" copies the canonical anchor plus optional manifest-entry context. +- `view.layout` values are registered `@` identifiers from the renderer registry; `view.visibleLanes` values come from the generated per-lens lane vocabulary, which is versioned with the application enums above. Restoring a URL whose layout or lane IDs are no longer registered shows an explicit "layout/lanes reset to default" notice and falls back to route defaults — a restored URL never silently no-ops. + +### 4.1 State ownership + +- **URL:** route; opaque profile/repository/project/worktree/ref/entity/saved-view IDs; non-sensitive time bounds; renderer/lens/layout; the committed `SelectionV1` (every variant, carrying only opaque IDs); facet IDs; transcript mode. Serialize arrays in stable sorted order and omit defaults. +- **Encrypted profile storage:** query literals, annotations, collections, protected saved views, replay input payload references, redaction decisions. URLs hold only an opaque `protectedDraftId` scoped to the local profile. +- **IndexedDB:** versioned bounded response cache, local uncommitted annotation drafts, route recovery checkpoint, deterministic layout coordinates keyed by snapshot/query/layout version. Payloads obey server sensitivity and retention metadata; locked/profile-sign-out purges protected records. +- **Local preferences:** theme, density, keyboard layout, panel geometry, last nonsensitive route, reduced-motion override. Never store entity payloads here. +- **Renderer-local:** hover, lasso-in-progress, drag state, provisional camera, worker job, GPU buffers. Commit selection/camera only on interaction end. + +`ScopeSelectorV2` (defined in plan 16 §4) and `ScopeResolutionV2` (defined in plan 01) are imported from the generated contract transported per plans 10/17; query state does not define another `mode/include/projectIds` selector. URL serialization retains the canonical selector's nonsensitive opaque roots/exclusions/time/policies/limits and the resolution ID; candidate details and safe aliases stay in the bounded cache. `retrievalAnchors` are server-issued domain `RetrievalAnchorId`s for session/thread/Turn/message/agent/subagent/workflow/goal/Git evidence. The browser uses `retrieval_anchors.metadata_batch_get` for bounded safe identity/state labels, `retrieval_anchors.resolve` only when an authorized inspector requests exact record/payload content, and `retrieval_recipes.execute` for a protected versioned rerun; it never treats metadata as payload authority. Anchors survive cursor, SSE, and migration response-handle expiry. Sensitive retrieval inputs remain behind `protectedDraftId`; copied links, saved views, collections, annotations, exports, and route recovery carry a `RetrievalRecipeV1` (defined in plan 01) or protected recipe ref, never an ephemeral response handle alone. + +Scope defaults and ambiguity behavior are fixed: + +- A new investigation starts at explicit active-profile `All`; cwd, last route, recent project, and selected entity never narrow it silently. +- The chooser is a lazy tree: All → repository → project → checkout/worktree → ref/snapshot, with explicit multi-select and an entity collection overlay. Project routes apply a visible filter over the same state. +- Every selected/candidate scope shows kind, canonical disambiguated `owner/repository/project/worktree/ref` label, authorized provenance, index generation, and fresh/stale/partial/unavailable state. Same-name items are never distinguished by color or truncation alone. +- Name/path/alias input calls generated scope resolution. Ambiguity opens a keyboard/touch-accessible candidate list; choosing one resubmits the preserved canonical request with its signed retry token in one step. The UI does not rebuild the query, guess by cwd, or ask the user to retype it. +- CLI/MCP/API equivalents exported from the workbench use the same opaque IDs and resolution token; scope semantics, candidates/order, provenance, coverage, and errors must match exactly. + +`dashboard/packages/query-state/src/url.test.ts` must prove canonical round trips (including every `SelectionV1` variant and A/B compare ranges), default elision, back/forward, unknown-version refusal, the lens-slug/union/enum equality fixture, unknown layout/lane-ID reset behavior, and absence of sensitive literal fixtures. `history.ts` debounces replace-state during brushing but pushes selection, route, compare, and committed time changes. + +### 4.2 Transcript modes and #410 seam + +Every transcript/session/Turn/search surface shows a persistent mode control with the seven `TranscriptMode` values. Each response includes the generated `TranscriptVisibility` block — a plan 10/17 schema type re-exported through `packages/contracts`, reproduced here for reference and never redefined as a local interface: + +```ts +export interface TranscriptVisibility { + mode: TranscriptMode; + rawRowCount: number; + normalizedRepresentativeCount: number; + visibleCount: number; + hiddenCopyCount: number; + hiddenByKind: Readonly>; + representativeSets: readonly { + representativeEventId: string; + memberSourceRefs: readonly string[]; + algorithm: string; + confidence: number | null; + }[]; +} +``` + +- `native_rows` compiles to domain `MessageView::NativeRows` and shows every sanitized stored source row plus original order/source offsets and redaction/coverage state. +- `normalized_representative` is the default and compiles to `MessageView::RepresentativeRows`; copied/native rows may group, but each group displays the suppression count, representative rule/version, source observations, expansion cursor, and every represented entity ID. +- `human_best_effort` compiles to `MessageView::HumanBestEffort`; each row retains domain `MessageOrigin` and unknown-origin counts remain visible. +- `direct_user` compiles to `MessageView::DirectUser` and shows excluded delegated/protocol counts plus one-click mode change. +- `delegated_agents` compiles to `MessageView::DelegatedAgents` and shows parent task/agent evidence. +- `tool_results` and `provider_protocol` compile to `MessageView::ToolResults` and `MessageView::ProviderProtocol` respectively; wrapper protocol is never conflated with actual tool results. + +“Show native rows” follows `messages.expand_native` or issues `NativeRows` at the same frozen snapshot. The frontend does not create a combined “both” result/count or a second classification algorithm. + +The exact generated wire values are `view=native_rows|representative_rows|human_best_effort|direct_user|delegated_agents|tool_results|provider_protocol`; frontend aliases are mapped by a checked generated table and never serialized by title-casing or guesswork. + +No empty state says “no messages” when another mode contains records. It says, for example, “0 direct-user messages; 18 delegated prompts and 42 protocol/tool rows are available.” Exports record mode, native/visible/hidden counts, representative membership, algorithm version, and privacy-domain-bound source fingerprints. + +### 4.3 Saved-view, collection, and annotation records + +These are the shareability deliverables, so they have explicit shapes. All three are generated in the plan 10/17 schema (routes in plan 10 §8.6) and re-exported through `packages/contracts`; the browser defines no parallel record.

The owning store is the server-side saved-view/collection/annotation store behind plan 10 §8.6; the browser holds them only in the bounded IndexedDB cache (section 8.1), with annotation bodies and protected query literals confined to encrypted profile storage. Size envelopes: a serialized `SavedViewV1` is `<= 32 KiB` (state plus refs; no payload text); a `CollectionV1` holds `<= 10,000` member anchors/refs and serializes to `<= 256 KiB`; an `AnnotationV1` body is `<= 4 KiB`. Records over-envelope are rejected by the command preview with the exceeded bound, not truncated silently. Embedded `InvestigationStateV1` restores through the same versioned codec as URLs: unknown versions are refused with an explicit incompatible state. + +## 5.

Route modules contain composition and data loading, not renderer algorithms or endpoint joins. +- Root `packages/tracedecay-client` is the only OpenAPI-generated TypeScript HTTP/problem/SSE schema/runtime. Dashboard `packages/api-client` is a small browser cookie/CSRF/bootstrap binding and re-export layer over that official package; it contains no generated schema or competing pager/event/problem types. `packages/contracts` provides UI-safe aliases/compositions over the official generated schema and may not duplicate transport/domain types. Tool-catalog generation owns `app/src/generated/{catalog,commands}.ts`; `packages/contracts` re-exports their typed IDs/schemas rather than generating a second catalog. +- `packages/data-client` is the only owner of TanStack Query keys, snapshot caching, SSE, IndexedDB cache, and capability gating. +- `packages/query-state` is the only owner of URL/history/persistence semantics. +- `packages/renderers`, `brain`, `timeline`, and `charts` own drawing; feature modules supply typed models and callbacks. +- Every feature has a route/container boundary and pure presenters. Containers call generated-client query/command hooks, translate the one `InvestigationStateV1`, and select a generated read model; presenters accept sealed models plus typed callbacks and never fetch, join endpoints, read URL/storage, inspect raw problems, or infer legal actions. +- Generated-client hooks are the sole network entry (`useSnapshotQuery`, `useCursorPage`, `useSubscription`, `useCapabilityCommand`, and `useOperation`). A lint forbids feature imports from `fetch`, Axum routes, raw OpenAPI internals, and V1 client modules. +- Global state is limited to the committed investigation, auth/capability/theme, and query cache. Each open saved-view/render instance owns an isolated `ViewInstanceStateV1` keyed by `(saved_view_id, instance_id)` for draft facets, grouping, column geometry, expansion, local selection gesture, scroll/window cursor, and renderer camera. Closing an instance destroys it; changing one board cannot mutate another instance or a canonical task. +- Optimistic UI follows one closed state machine: `idle → optimistic_pending → accepted_projection | conflict_reverted | rejected_reverted | operation_pending → accepted_projection | failed_reverted`. The pre-command model/version is retained until an accepted projection arrives. Conflicts render server/current versions and legal retry/rebase actions; partial batch results revert only failed items. This is client-state reconciliation, not a curation preview/apply/rollback workflow. +- Each renderer creates at most one Canvas/WebGL context and one worker pool. Hidden routes suspend workers and animation frames and release large GPU buffers after a bounded idle period. +- `features/*` may depend on packages, never another feature's internal files. Shared functionality moves to a package after two proven consumers. +- No package imports V1 plugin source. Migration adapters live at the route boundary only while the explicit migration flag is active and disappear at cutover. +- The `dashboard/` workspace uses exactly one package manager: npm with the committed `package-lock.json` (`npm ci` in CI). Root `packages/tracedecay-client` is a separately managed workspace whose generation/test commands run under its own toolchain; the dashboard consumes only its built artifact. No pnpm lockfile, script, or command appears under `dashboard/`. + +## 6. Bundler ADR and embedded-asset boundary + +Create `docs/adr/dashboard-v2-bundler.md` before choosing a config filename. Measure the current Rsbuild/Rspack pipeline against a Vite prototype using the same shell route and lazy graph chunk. The ADR (benchmark evidence, decision, rollback path) lands as its own reviewable PR and merges before any bundler config file or implementation commit; Task 2's application-shell work starts from the merged decision so the ADR gate stays independent of the winning bundler's implementation. + +The ADR matrix records: + +| Dimension | Required evidence | +|---|---| +| Production build | cold/warm duration, peak RSS, emitted chunks, gzip/Brotli sizes, deterministic hash behavior | +| Development | startup, first transform, HMR latency for TSX/CSS/worker, proxy/SSE behavior | +| Rust embedding | manifest generation, base path, history fallback, immutable asset cache headers, `include_bytes!` integration | +| Code splitting | shell budget and lazy graph/timeline/editor chunks without dynamic public paths | +| Security | CSP without `unsafe-eval`, worker loading, source-map publication, asset path containment | +| Migration coexistence | current single-file plugin bundles and Hermes wrapper only behind the bounded per-domain migration flag | +| Tests | Vitest, Playwright, type checking, coverage, deterministic production preview | +| Packaging | fresh `cargo package`, crates.io prebuilt assets, no Node at runtime/docs.rs | +| Migration risk | changed scripts/files, rollback path, bounded old/new shell build, atomic removal of stale live routes/names at cutover | + +Acceptance weights correctness/embedding/CSP/history/migration safety above raw build speed.

Keep `dashboard/build.shared.mjs` and old dist emission until the last legacy plugin retires. + +## 7. Generated contracts, read-model envelopes, and commands + +The plan 10/17 contract generator emits discriminated unions for entity/event/relation kinds, `ScopeSelectorV2`/`ScopeResolutionV2`, `RetrievalAnchorRecordV1`, sink-eligible/redacted content states, query rows, commands, capabilities, privacy status, replay records, `ApiProblem`, and SSE events at root `packages/tracedecay-client/src/generated/schema.ts`. CI runs generation then requires a clean tree. Dashboard `packages/api-client` is only the thin browser-auth binding over that artifact, not a divergent generated client fork. + +Every route consumes the generated plan 10/17 `ApiResponse` without redefining its envelope: + +```ts +export type ReadModelEnvelope = ApiResponse; +``` + +`ApiResponse.meta` always includes request/use-case, protocol, catalog digest, `ScopeResolutionV2`, snapshot, coverage, freshness, redactions, retention, applied limits, and warnings. Feature code cannot construct a smaller meta object. + +Paged feature data uses the one generated `CursorPage { items, next_cursor, truncation, count_semantics, ordering }` defined in plan 17's contract IR; Brain/graph/timeline data carries its own generated LOD and allowed-action fields. `CoverageStatusLine` renders all nonempty dispositions, sampling/truncation, freshness, redactions, retention, warnings, and a “why?” link. A feature may specialize the copy but cannot return `data` alone or drop `meta`. + +Problems use the one generated `application/problem+json` `ApiProblem { problem_type, title, status, code, detail, instance, retry, current_version, restart, current_binding, candidates, invalid, operation }`. `packages/api-client/src/errors.ts` preserves these fields while redacting response/token bodies from logs. Invalid fields bind to form controls; `current_version` opens conflict review; `current_binding` supports cutoff recovery; candidates drive scope disambiguation; `operation` opens durable status; `restart` invalidates cursor/subscription/snapshot as directed. Retry never guesses from HTTP status alone. + +Commands use generated types and this interaction contract: + +1. Capability advertises action, scope, destructive class, preview requirement, and required version. +2. UI opens a typed preview. Destructive previews list descendants, redactions, holds, irreversible effects, and exact scope. +3. Confirm submits an opaque idempotency key and `ifVersion`/watermark; it never reuses a timed-out key for different input. +4. `409` presents current-versus-requested state and offers refresh/review, never blind retry. +5. Accepted commands return operation/event IDs; UI follows their projection status through the live feed and links to audit evidence. + +The dashboard never exposes arbitrary SQL, file path mutation, shell, or policy bytecode execution. + +## 8. Cache, snapshot, and live SSE model + +### 8.1 Query keys and cache bounds + +`packages/data-client/src/keys.ts` uses: + +```ts +type QueryKeyV1 = readonly [ + "v2", + profileId: string, + capabilityVersion: string, + routeModel: string, + queryFingerprint: string, + scopeFingerprint: string, + timeFingerprint: string, + transcriptMode: TranscriptMode, + cursor: string | null, +]; +``` + +Sensitive text is represented only by an opaque server-issued fingerprint. Frozen snapshots are immutable and cacheable until retention/schema invalidates them. Live snapshots have bounded freshness and are changed only by typed deltas or full resync. IndexedDB stores at most the last 20 nonsensitive route snapshots and a configurable protected-cache quota; LRU eviction deletes payload chunks before metadata. Cache entries carry schema/access/retention digests and are rejected, not migrated heuristically, on mismatch. + +Abort previous route/brush requests on supersession. Prefetch only the selected entity inspector and adjacent timeline page; never prefetch all shards or payload bodies. + +### 8.2 SSE state machine + +Subscriptions are created by `POST /api/v2/subscriptions` using a protected request body and return `{ subscription_id, expires_at, snapshot_watermark, replay_retention, stream_path }`. The browser opens the returned `GET /api/v2/subscriptions/{id}/events` with `Last-Event-ID` only on resume and invokes `subscriptions.revoke` through `POST /api/v2/subscriptions/{id}:revoke` on explicit close when reachable. Query literals never appear in the SSE URL, subscription ID, event ID, or logs. + +```text +idle → snapshot_loading → live +live + duplicate/out-of-order → live (idempotently ignored) +live + coverage delta → live/partial (visible status change) +live + gap/resync-required → stale_visible → snapshot_loading +live + network loss → reconnecting → live | stale_visible | offline_visible +any + auth/schema/access mismatch → blocked with explicit recovery +``` + +The generated `ApiStreamEvent` union is `Snapshot | Delta | Operation | Projection | Coverage | Gap | ResyncRequired | ServerNotice`. `delta-reducer.ts` accepts only increasing authenticated stream event IDs, then applies generated per-change stable IDs/vector watermarks idempotently; it does not invent a `(shard, entity)` identity that operation or aggregate streams may lack. It preserves remove/upsert boundaries, applies `Coverage` as first-class state, and batches animation-free DOM commits per frame. `Operation` follows command/job/workflow/export/migration/automation receipts to explicit terminal state and never treats HTTP `202` as completion. A gap freezes the last-known-good snapshot, disables mutation commands tied to its version, and announces the resync. Exponential backoff uses jitter and pauses while the page is hidden or offline. Subscription IDs and `Last-Event-ID` remain page-memory-only capability material. Resume occurs only within advertised retention; otherwise the server sends `ResyncRequired`. + +The client treats 15-second SSE comment heartbeats as liveness only; they consume no semantic sequence and never trigger React updates. The server queue is bounded at 256 frames/2 MiB per connection. A slow consumer receives resync/close behavior; the browser cannot continue displaying the stream as complete after that close. + +Tests inject duplicate, out-of-order, coalesced, missing, stale, schema-changed, access-changed, slow-consumer, and disconnect/reconnect streams. No test may use time sleeps; fake clocks and explicit event advancement make the state machine deterministic. + +## 9. Workbench shell and universal inspector + +### 9.1 Command/status bar + +Left to right: + +- product/home mark and route breadcrumb; +- profile-wide scope control defaulting explicitly to All, with lazy repository/project/worktree/ref hierarchy, multi-selection, disambiguated safe labels, provenance/freshness, and ambiguity retry; +- occurred-time range plus live/frozen/as-of state; +- global query opener and keyboard shortcut; +- compare toggle with explicit A/B periods/entities; +- coverage/health summary; +- save, share, and export actions; +- command palette and settings. + +The palette is generated from the versioned capability/tool catalog. Each item shows intent, read/mutate class, evidence source (`local semantic`, `live delivery`, `joined`), required scope, estimated cost, and unavailable reason. Git-intent searches offer the catalog-generated guided inputs for branch listing/search/diff, PR and commit context, changelog, session lookup, and workflow capabilities; the palette enumerates these entries from the versioned catalog at build/run time and never hardcodes a V1 tool-name list that could fossilize. Joined GitHub/local actions display both freshnesses and a reconciliation state; drift never looks like a unified truth. + +### 9.2 Universal inspector + +The inspector works for entity, event, aggregate, path, relation, time range, and comparison selections — each a `SelectionV1` variant (section 4), so every supported selection kind is shareable and restorable through the URL: + +- **Summary:** type, label, time/scope, observed/inferred status, coverage, key measures. +- **Evidence:** supporting observations/events, source position and privacy-domain-keyed fingerprint identity, evidence class, algorithm, and confidence. +- **Relations:** incoming/outgoing typed relations, legal pivots, redacted frontier counts, bounded expansion. +- **Native:** sanitized native source row, normalized observation, canonical event, projection row, schema/privacy versions; authorization and transcript mode apply. This tab never opens protected-quarantine plaintext. +- **History:** versions, valid/observed intervals, supersession, corrections, late arrivals. +- **Actions:** generated allowed commands with preview/audit; no action is inferred from UI entity type alone. + +Every inspectable research entity exposes “copy stable anchor” and “re-run retrieval recipe.” Resolution shows identity/version/watermark drift and coverage before navigation. A cursor or old response handle can page a current result but is never displayed as the durable research identifier. + +Aggregate selection lists exact or sampled membership, denominator, hidden counts, expansion cursor, watermark, and algorithm version. Relation selection explains endpoint identities and why the connector is causal, structural, inferred, similarity, or temporal. Inspector tabs are keyboard-addressable; closing restores focus to the selected mark/row. + +## 10. Brain / All implementation + +The default Brain answers one question in this reading order: + +1. **First-scan claim:** one server-authored, evidence-linked sentence naming the most consequential current activity or health issue plus scope, time, coverage, and confidence. +2. **Focal topology:** recent project/workflow/agent plus initiative/plan/task/attempt clusters connected by typed activity, dependencies, blockers, leases, and acceptance evidence, selected to match the claim and current time window. +3. **Aligned activity:** work/attempt, agent, code, delivery, knowledge, and automation lanes below the same time window. +4. **Health guardrail:** compact project × subsystem matrix for ingest, projection, query, storage, privacy, and remote freshness. +5. **Learning loop:** hint/tool/fact/skill/automation candidate→use→outcome funnel with unresolved horizon. +6. **Resume:** unfinished initiatives, plans, work items, attempts, blockers, expiring leases, pending acceptance/review, workflows, goals, agent runs, and saved investigations. + +This is a spatial reading path, not six equal cards. On desktop the topology dominates; subordinate sections use open bands. On mobile the claim, one focused cluster, and one activity lane appear first; health/learning/resume live in sheets. + +All/Brain is federated across the selected repositories/projects/worktrees/refs. Nodes, aggregate membership, edges, inspector titles, tables, and exports retain canonical repository/snapshot identity and per-shard provenance/freshness/partial state. Same-name projects, branches, files, symbols, sessions, or agents use disambiguated labels and never merge by display text; cross-repository connectors require typed dependency/session/workflow/Git/evidence relations. + +### 10.1 Brain aggregate tile contract + +`BrainTile` is the generated plan 10/17 aggregate-tile read model re-exported through `packages/contracts`; the browser never declares it as a local interface. Reference shape: + +```ts +export interface BrainTile { + id: string; + kind: "profile" | "project" | "workflow" | "agent_cluster" | "domain_cluster" + | "initiative" | "plan_cluster" | "task_cluster" | "attempt_cluster" + | "blocker_cluster" | "lease_cluster" | "acceptance_cluster"; + label: string; + membership: { exact: boolean; count: number; denominator: number | null; sampled: number | null }; + activity: Readonly>; + edgeCounts: readonly { kind: string; evidenceClass: string; count: number }[]; + coverage: CoverageSummary; + hiddenChildren: number; + expandable: boolean; + expansionCursor: string | null; + layout: { algorithm: string; version: string; seed: string; anchor: [number, number] | null }; +} +``` + +Semantic zoom: + +- L0 profile: projects/workflows/agents/work/plan/task/attempt/lease/acceptance and domain health. +- L1 project/workflow/initiative/plan: work items, blockers, attempts, leases, acceptance/review, worktrees, branches, sessions, runs, memory, code snapshots, and delivery. +- L2 neighborhood: selected entities and bounded typed relations. +- L3 evidence: exact message, visible reasoning artifact, tool event, diff, diagnostic, fact source, policy evaluation, artifact, or delivery record. + +Expansion preserves existing positions, requests only child tiles/neighborhood, and animates no more than 250 ms unless reduced motion is set. The legibility budget is numeric: at most `250` labeled marks in the viewport, at most `2` overlapping label pairs per `100` labels, and no effective label smaller than `11 px` after zoom. If topology exceeds any of these bounds, the UI increases aggregation or switches to matrix/outline; it never merely hides labels. The performance suite asserts the bounds against the fixture corpus. + +### 10.2 Graph-of-graphs lens contracts + +| Lens | Nodes | Edges | Primary layout | Required coordinated evidence | +|---|---|---|---|---| +| Git | repos, worktrees, refs, commits, PRs, checks, reviews, releases | ancestry, points-to, produced, observed, encountered, delivered | layered + history rail | live/local freshness and drift | +| Code | snapshots, files, stable symbols, occurrences, diagnostics, tests | contains, calls, types, uses, changed-to, affected | layered/radial/matrix | source/diff/test/impact evidence | +| Threads | sessions, Turns, messages, reasoning artifacts, summaries, goals, tools | contains, follows, summarizes, used-context, produced | layered outline | native/representative/audience counts | +| Agents | actors, agent instances, tasks, goals, handoffs | spawned, delegated, messaged, joined, interrupted, completed | stable parent tree | provider/host/workflow meaning | +| Tasks | initiatives, immutable plan/work-item versions, gates, assignments, attempts, executors, packets, artifacts, outcomes | decomposes, requires, verifies, synthesizes, assigned, leased, attempted, handed-off, produced, accepted | plan outline/dependency DAG/critical path | readiness, exact scope, route/lease/packet/evidence versions | +| Plans | initiatives, plans/subplans, work-item DAGs, project sets, repositories, milestones, decisions | expands-to, blocks, supersedes, spans, unlocks, delivers | graph-of-graphs + semantic zoom | immutable version diff and active-attempt impact | +| Turns | Turn, context snapshot, messages, goals, tools/results, code, hints, outcomes | visible-at-start, invoked, produced, affected | compact layered DAG | explicit Turn interval and coverage | +| Timeline | events/intervals/density bins | source order, causal, correlation, temporal | lane/time | occurred and ingested time | +| Memory | facts/versions, entities, decisions, contradictions, retrievals, feedback | source, supports, contradicts, supersedes, retrieved, rated | provenance DAG/cluster | trust/version/retention | +| Automation | jobs, schedules, runs, actors, candidates, artifacts, skill/memory versions, uses, outcomes | scheduled, spawned, proposed, validated, auto-decided, autonomously-applied, injected, observed, automatically-recovered | waterfall + lineage DAG | config/policy/actor identity | + +Selecting any node changes the common selected entity and reveals cross-lens pivots. Switching lenses preserves time/scope/selection/pins. Edge keys and inspector language are lens-specific; shared visual geometry does not erase semantics. + +## 11. Universal Explorer + +Explorer has three synchronized authoring modes: + +- plain-language intent compiled by the server into visible `TraceQueryV1`; +- structured builder for scope, kinds, predicates, text, graph/time operators, grouping, ranking, fields, and limits; +- source-form `TraceQueryV1` editor with schema completion and safe validation, never SQL/FTS syntax. + +The search builder exposes one versioned evaluated retrieval profile with inspectable stages—not a magical semantic toggle: + +- lexical token/field and exact phrase; +- typo-tolerant fuzzy with visible edit/candidate cap; +- entity/symbol/alias resolution; +- optional semantic/vector candidates; +- graph-neighborhood relation candidates; +- recency/activity prior; +- explicit origin/kind/provider/session/agent/project/ref/time/sensitivity filters; +- representative grouping/dedupe with native membership and expansion. + +Users may disable stages or choose a benchmark-proven profile. The UI never claims embeddings improve results; vector-disabled/unavailable/regressed is visible, and exact literal/phrase hits cannot be demoted below a profile's locked exact-match floor. Search results state stage matches, score components, candidate universe, caps/exclusions, grouping membership, coverage, and benchmark profile/version. + +The result surface pivots between precise table, timeline, graph, matrix, distribution, small multiples, and saved collection. All pivots consume one response snapshot and disclose unsupported encodings. Result rows expose type, primary label, time, scope, evidence class, match reason, score components, coverage, and source mode; selecting opens the inspector. + +Query Explain shows canonical AST/fingerprint, validation, cost/budget, selected and pruned shards, pushed/residual filters, FTS/vector/graph/time operators, ranking components including absent features, candidate universe, per-stage caps, cap-induced exclusions, stable sort key, cursor/watermark, timing, coverage, truncation, message-origin/view semantics, and retention. Noisy ranking can be diagnosed from exact score components and bounded candidates; capped/ambiguous results never look complete. Export equivalent current CLI/MCP/HTTP requests plus a stable retrieval recipe from the server-generated representation so the UI does not reinvent syntax or preserve stale names. + +Explorer's checked benchmark panel runs the versioned redacted corpus by slice: exact literal, phrase, misspelling, symbol/entity/alias, origin ambiguity, cross-project concept, graph-related, recency, no-result, capped, adversarial noise, and embedding regression. It reports MRR, nDCG, Recall@k, Precision@k, zero-result rate, p50/p95 latency, candidate counts, coverage, and per-slice deltas. It is an evaluation artifact, not a vanity score; any exact-match/origin-filter regression blocks profile promotion. + +One mandatory cross-repo slice spans Rspack, Rsbuild, and React Router repositories/worktrees/benchmarks with same-name files, symbols, branches, sessions, and known dependency/PR evidence. It verifies repo disambiguation, federated graph links, scope candidates, ranking relevance, provenance, and stale/partial labels across CLI/MCP/API/dashboard outputs. + +Collections retain stable research anchors plus entity/event/relation refs, retrieval recipe, snapshot/watermark, and annotation refs — the `CollectionV1` record of section 4.3. Compare aligns by stable entity identity, Turn boundary, commit, or explicit anchor; unaligned items remain visible. Expired page cursors/response handles never invalidate a collection. + +## 12.

Routine success noise may aggregate but remains in counts/export and expands deterministically. + +### 12.2 Time and causality behavior + +- Use occurred time for placement and ingested time for a late-arrival marker. Missing occurred time uses a labeled ingest-time fallback. +- Frozen views never reorder. Live late events appear through a visible “new historical event” marker; accepting refresh creates a new snapshot. +- Interval selection uses `[from, to)` and reports clipped lanes/events. +- Direct structured touches and inferred affected entities render separately. +- Causal connectors require evidence; temporal proximity uses a neutral connector and never an arrow. +- The bounded causal chain is `context before → visible rationale/decision → action/tool → result → code/artifact → test/delivery → downstream impact`. + +### 12.3 Turn inspection + +A committed Turn selection shows: + +- start/end, actor/agent/provider/host/session/workflow and parent Turn; +- context snapshot visible at start, including summary/LCM lineage and retrieval/memory/hints; +- direct-user/delegated-agent/tool-result/provider-protocol/unknown origin counts and native/representative expansion; +- provider-exposed reasoning artifacts with `summary`, `analysis_text`, `structured`, `encrypted`, `redacted`, or `unavailable` format; +- goals/tasks at start, updates during Turn, terminal state; +- tools/results, approvals, errors, retries, latency; +- files/symbols/patches/diagnostics/tests and evidence-bearing impact; +- Git/worktree/branch/commit/PR state encountered or produced; +- output messages, cost, tokens, compression, downstream outcomes, and coverage. + +Reasoning is excluded from search, embeddings, export, and saved annotations by default and respects shorter retention. Missing or encrypted artifacts render coverage markers, never inferred chain-of-thought. + +### 12.4 Follow, compare, and time machine + +- Follow one agent: keep its lanes expanded, collaborators summarized, and delivery impact visible. +- Compare sessions/agents/branches/models/policies/time ranges: align on user Turns, commits, goals, or manual anchors; show missing intervals and coverage. +- Scrub as-of: project/worktree/ref/snapshot, visible messages/context, fact/memory versions, hint/policy/config/tool catalog, open goals/tasks/workflows, and observed delivery state. +- Exact replay requires immutable artifact/config/candidate/index/memory/catalog manifest; recorded replay verifies stored result; best-effort lists substitutions. + +### 12.5 Timeline windowing contract + +The Loom's client data contract for large corpora is typed, generated in the plan 10/17 schema (density-bin fields lifted from master plan §14.2 into schema), and re-exported through `packages/contracts`: + +```ts +export interface DensityBinV1 { + laneId: string; + bucketStart: string; // occurred time; half-open [bucketStart, bucketEnd) + bucketEnd: string; + exactCount: number | null; // exactly one of exactCount/sampledCount is set + sampledCount: number | null; + denominator: number | null; + hiddenCount: number; + lateCount: number; + coverage: CoverageSummary; + aggregationVersion: string; + firstEventCursor: string | null; // bin → EventPageV1 linkage for drill-down +} + +export interface LaneWindowV1 { + laneId: string; + window: { from: string; to: string }; + totalLogicalRows: number; // server total; drives virtualized row count (§16.1) + loadedPageCursors: readonly string[]; + evictionWatermark: string | null; +} + +export interface EventPageV1 { + pageCursor: string; // PK within (laneId, window) + laneId: string; + events: readonly string[]; // canonical event IDs; rows hydrate via generated read models + nextCursor: string | null; +} +``` + +Keys, envelopes, and paging policy: + +- A density bin is keyed by `(laneId, bucketStart, aggregationVersion)`. One density request returns at most `2,000` bins; if the requested window/zoom would exceed that, the server raises aggregation and reports it in `coverage` — the client never bins events itself. +- An event page holds at most `500` events and `<= 1 MiB`; the client prefetches at most one page ahead and one behind the viewport and evicts by LRU beyond `12` retained pages per lane, deleting payload chunks before metadata (same policy as section 8.1). +- Virtualized transcript/table row counts and scroll positions derive from `LaneWindowV1.totalLogicalRows` (the accessibility row-count source of section 16.1), never from loaded-page length; unloaded rows render as fetchable placeholders with position preserved. +- Size envelope: the recorded fixture corpus pins `388,000+` messages and the 250k-density-mark budget; at hour buckets that is ~8,760 bins per lane-year, so ~28 lane-years fit the mark budget before the server must raise aggregation. `dashboard/tests/performance/timeline` includes a 388k-message fixture exercising binning, paging, prefetch, and eviction at this scale. + +## 13. Domain workspaces + +Scope and persistence are visible product semantics, not hidden implementation detail: + +- Every fact, memory version, skill, policy, automation, saved investigation, and annotation shows a plain-text owner line (`profile`, `cross-project`, or named project), privacy domain, and source evidence in its summary/history; this is not a decorative badge. +- Human-authored non-curation create/import commands and autonomous curation effects require an explicit generated `DeclaredScope`. Opening a project route or filtering All to one project never preselects ownership silently; no fact/memory/skill item proposal/apply control exists. +- Existing-target actions use the entity's canonical owner and disable with an ownership-conflict explanation if the request state disagrees. Moving ownership opens the dedicated migration inspect/plan workflow; it is not an editable field. +- Cross-project use links to one durable source version through evidence relations. The UI never offers “copy to project” as a shortcut for memory, skill, policy, or automation reuse. +- Mixed All-scope lists group/filter by owner without changing identity. Profile-owned and project-owned histories remain distinguishable in tables, graphs, exports, URLs, and replay manifests. + +### 13.0 Work, plans, tasks, and executors + +- The canonical selection is initiative/plan-version/work-item/attempt IDs plus frozen/live watermarks. A board is a protected saved `TraceQueryV1` and lens; changing board, repository, agent, executor, or layout never copies or rehomes tasks. +- A `SavedTaskViewV1` round-trips the complete server contract: protected canonical query/digest with mandatory explicit `query.scope` and derived scope digest, projection/lens/group/sort/layout, owner/sharing grants, live or exact frozen plan/entity/projection versions and watermark, config/catalog/schema versions, optimistic view version, timestamps, and revocation. It defines no second saved-view scope selector. Multiple overlapping view instances remain isolated; reopen never falls back from missing frozen inputs to current state. Share revoke invalidates the exact grant/subscriptions without deleting the owner's view. +- Initiative overview shows exact cross-project scope, plan version, dependency/fan-in state, critical-path interval/slack, budgets/deadlines, active agents/executors, costs, outcomes, coverage, and links to Goals/workflows/code/Git/PR/check/release evidence. +- Plan outline, Kanban, dependency DAG, critical path, timeline, causal, workload, executor-fleet, repository-work, initiative, agent-relevant, and All views preserve identical IDs/counts/selection. This is plan 24's projection vocabulary exactly: §0.21's saved projections plus §12.5's Executor Fleet/Repository Work lens names and §12.7's agent-relevant slice; 11 renders no view name outside that set. Drag/drop invokes only generated legal commands; derived readiness cannot be set directly. Workload and Executor Fleet runtime/cost/rate/denominator views consume plan 26/PR 30J generated accounting/liveness projections and retain attempt/work-item/executor/route/model/effort drill-down refs, methodology, watermark, and unknown/capped state; the browser never aggregates its loaded rows into a total. +- One saved view exposes switchable Kanban, DAG, timeline, table, workload, and cross-repository bundle projections over the same authorized `TraceQueryV1`, frozen/live watermark, canonical membership, sort/group specification, and selection. Switching mode preserves filters, selected IDs, exact totals, and per-view camera/column/scroll state; it does not create another saved view or refetch an unbounded board. +- Kanban is server-grouped and cursor-windowed by derived lane/reason. Columns virtualize horizontally; cards/rows virtualize vertically with at most three viewports overscan. Initial hydration includes IDs, safe labels, readiness/reason, assignment/route summary, attention/progress, and versions only; inspector/detail/artifact bodies hydrate on selection. A 388k-item fixture must keep DOM rows below 600, initial payload below the §19 route budget, and keyboard logical row/column positions exact. +- Multi-select is an explicit mode with selected count/scope and one inline generated batch validation/effect view. The catalog-generated result discriminant is either `AtomicAllOrNone` (one committed/rejected transaction with deterministic per-item validations) or `PerItemPartial` (per-canonical-ID accepted/version-conflict/denied/stale/unavailable/failed outcomes). Only `PerItemPartial` may advance accepted rows while failed rows remain selected; an atomic rejection advances none. A partial failure never appears as all-success or as an `AtomicAllOrNone` receipt. +- Drag/drop is optional pointer shorthand for a generated legal command, never raw lane mutation. Keyboard/touch users choose “move/change…” then a legal destination/action list with reason, impact, and confirmation requirement. Dependency-blocked/readiness states cannot be overridden by presentation movement. +- Ordinary edits (title/specification metadata, saved-view filters, assignment/priority when policy permits) commit directly through the cataloged expected-version command and show version history; the UI invents no generic undo/rollback token. Archive is soft presentation retirement: it preserves canonical identity, relations, attempts, anchors, and audit and can be reopened by the cataloged versioned command. Worktree deletion, force-affecting Git, merge/release, protected-data deletion, and other irreversible/external effects use their operation-specific confirmation/compensation contracts. Curation candidates/effects remain fully autonomous and expose history/outcomes, not proposal controls. +- Multi-select route assignment invokes one generated `work_items.assign_set` command, shows the bounded affected set/constraints inline before the direct transaction, and accepts only an `AtomicAllOrNone` receipt with deterministic per-item validation. The renderer rejects a `PerItemPartial` discriminator for `assign_set`; E2E fixtures cover full commit, one-item validation rejection with zero commits, and malformed mixed results. It never loops singular commands client-side. Shared execution renders an aggregate parent plus independently leased child work items; it never depicts two authoritative leases as co-owners of one task. +- Task/attempt inspector covers versions, gates, acceptance, assignment/route rationale, requested versus actual host/provider/model/reasoning effort/tools/skills/grants, fenced lease state, packet/omissions, workspace/ref/snapshot, Turns/tools/artifacts/handoffs/outcomes, cancellation/reconciliation, costs, audit, and anchors. +- Generated legal actions expose `work_items.record_attestation`, `record_review`, `record_decision`, `record_exception`, `handoff`, `reopen`, and `reverse_transition` exactly. Attestation/review/decision/exception/handoff dialogs require the typed evidence/version/grant fields and cannot set derived readiness/acceptance directly; reopen creates a successor work-item version; reverse-transition shows the exact compensating edge and receipt and is never labeled generic “undo.” +- Work status/diagnostics/live changes use `task_graph.status`, `task_graph.doctor`, and the `task_graph.events` canonical subscription kind. The UI never polls a second board database or invents `/task-events`. +- Attempt navigation is a first-class paginated list/detail/timeline over `attempts.list/get/timeline`, not a hidden work-item expansion. It distinguishes every immutable attempt, state event, retry/defer reason, requested/actual route, start packet, current accepted packet, effective Turn boundary, lease/fence, and imported nonauthoritative execution-observation lane. +- The executor offer inbox uses registration-scoped `task_offers.list/get`. An offer is visibly advisory—never a claim or lease. An authenticated executor may accept (atomically yielding the one attempt/lease/start manifest) or decline; scheduler/admin revoke is separately authorized. Expired/declined/revoked offers never look like failed attempts, and a dashboard observer cannot impersonate an executor. +- Packet history uses `context_packets.list/get` to compare sealed ordinals, omissions, source/access/config/catalog drift, start/accepted/superseded/expired state, and anchors. Only the active executor capability may invoke fenced `context_packets.accept` with the exact prior packet and safe Turn boundary; the UI has no generic current-packet setter and never rewrites the immutable start packet. +- Task inspector maps the Hermes-derived anatomy without inventing another tab union: metadata/specification → `summary`/`specification`; status and legal actions → `summary`/`actions`; `DiagnosticEnvelopeV1` list → `evidence`/`actions`; dependencies → `dependencies`; attachments/comments/handoffs → `decisions`; canonical events → `history`; protected worker log → `evidence` with authorization; run history → `attempts`. Attempt selection reuses the same URL/inspector model. Unknown diagnostic action kinds remain visible and disabled with update guidance. +- Attention is a server-authored ranked strip over plan-06 `AttentionSignalV1`: stale advisory work claim, stale/expiring authoritative lease, aging blocker, repeated retry, unresolved effect, protocol violation, packet invalidation, critical-path risk, or material sibling change. Server supplies tier/age basis/watermark/evidence; the client never diffs clocks or treats attention as task truth. Staleness rings always include a text tier and exact last evidence time. Progress shows completed/total when both are known, indeterminate otherwise, and never derives percent from status or message volume. +- Overlap overlay distinguishes authoritative leases/writable-resource reservations, advisory `WorkClaimV1`, intentional ensemble/shared-work children/parallel roles, canonical query-scope overlap, and weak proximity. It shows exact overlap evidence/TTL without sibling prompt text and never labels a work claim as execution ownership. +- Agent default is the active attempt plus blockers/parents, material siblings, decisions, acceptance, handoffs, packet entries, and workspace conflicts. All work requires an explicit human authorization/scope expansion. +- `/work/notifications` owns the plan 24 §12.7 human notification-subscription UI: explicit saved filters/channels with event classes, quiet hours, dedupe, rate budgets, and authorization, edited through direct validated `task_notifications.create/update/delete` commands with expected version/idempotency. Task state never auto-subscribes the creating profile/channel, and dashboard toasts, gateway messages, hook hints, and task comments share no accidental notification loop. + +### 13.1 Sessions + +- Complete paginated session list and complete sanitized-native message enumeration, lossless for retained non-secret structure/semantics. +- Provider/model/role/kind/origin/time/project/Git/workflow filters. +- Explicit transcript modes and counts from section 4.2. +- Turn graph/outline, parent/subagent tree, Claude workflow/Codex goal links, context compression, cost, and direct code/delivery impact. +- Sanitized-native source, normalized observation, canonical event, and projection tabs with offsets/privacy-domain-bound fingerprints. + +### 13.2 Agents + +- Actor identity versus agent instance versus provider workflow identity. +- Stable parent/subagent tree, Turn sequence, delegation, inter-agent messages, handoffs/joins/interruptions, goals, tools, outcomes, retry/failure patterns. +- Compare providers/models/sessions/projects without conflating a logical actor with a process/run. + +### 13.2A Coordination + +- Presence is an expiring evidence claim with agent/provider/host, same or parallel worktree, repository/ref/revision, workflow/goal/Turn, observed/expires time, source, confidence, and unknown-after-expiry state. A missing row never means “no other agent.” +- Nearby ranking separates same worktree, parallel worktree/same repository, overlapping ref, direct file/symbol/test/goal/review overlap, and weak temporal proximity. Direct overlap lists evidence and stable research anchors; temporal-only proximity is neutral and never labeled conflict. +- The main artifact is a ranked overlap ledger synchronized with a compact worktree/agent map. Each row shows recipient-authorized domain `SafeCoordinationSummary` backed by `CatalogSafeText`, exact coverage/freshness, stable retrieval recipe, and legal `inspect/message/handoff/ack/suppress` actions. Prompt injection requires a separate `PromptEligibleText` conversion/policy receipt. The table is the precision/accessibility authority. +- `message`, `handoff`, `ack`, and `suppress` use the generated direct/resumable commands with an inline disclosed-summary/effect view, expected claim version, idempotency, and receipt; there is no generic preview/apply pair. Delivery, acceptance, acknowledgement, suppression, expiry, and resolution are distinct states; a sent message never appears as an acknowledged handoff. +- One dynamic coordination hint may appear in the command/status rail for the highest material actionable overlap. It includes one sentence, one stable anchor, one primary action, “suppress,” and why-now evidence. Per agent/pair/work-claim dedupe, cooldown, acknowledgement, and suppression prevent repeat prompts; lower-ranked overlaps remain in the workspace, not stacked notifications. +- Analytics show eligible/material/selected/delivered/inspected/messaged/handoff/ack/suppressed/expired/resolved/duplicate-prevented/unresolved with denominators, coverage, and horizon. No outcome is inferred from later code proximity alone. + +### 13.3 Code + +- Repository/snapshot/file/stable-symbol/occurrence graph and lineage. +- Session/agent ownership overlays labeled direct, inferred, or unknown. +- Diff graph, dependency matrix, cycles/coupling, diagnostic/test and affected-test overlays. +- Branch/commit/as-of slider and snapshot comparison; CodeMirror source/diff with exact locations and redaction decorations. +- `move_symbol` is a generated operation, never a browser rewrite helper. `code.move_symbol.inspect` shows the exact source/destination diff, inserted destination imports, caller/dependency/visibility/collision/module/cycle/orphan/cfg impact, snapshot/version, affected tests, and no caller auto-edit; `code.move_symbol.commit` requires confirmation, revalidation, repository/worktree grant, recovery/reindex operation, and durable receipt. + +### 13.4 Knowledge + +- Facts, versions, entities, decisions, contradictions, provenance, trust changes, feedback, retention, holds, supersession, and deletion lineage. +- Graph-resident holographic memory is durable user data, not a disposable code-index cache; graph-generation cleanup and reindex controls must never imply that facts or fact-entity relations will be deleted. +- Retrieval history and candidate explanations. +- Curator/reflection candidates and exact source→candidate→validation/policy→autonomous effect→use/outcome→autonomous revision/recovery chain; imported approval/apply events are labeled historical/provider evidence. +- Similarity projection, provenance graph, version table, and nearest-neighbor table; projection never replaces precise scores. + +### 13.5 Delivery + +- Worktrees, branches, commits, PRs, checks, reviews, releases, and remotes. +- Separate produced, observed, and merely encountered artifacts. +- Local semantic snapshot and live delivery facts display separate fetched/indexed timestamps, head/base/merge-base, changed-file digests, coverage, and reconciliation. +- Drift blocks joined impact claims and offers refresh-live, reindex-local, or recompute-both actions. + +### 13.6 Automations, skills, and autonomous curation + +- Schedules, effective config/policy source, locks/leases, skip reasons, run waterfall, actors, artifacts, candidates, validation, autonomy decisions, automatic effects/recovery, and downstream adoption. +- Capture Claude workflow runs, Codex goals, and Hermes-style curator/session-reflector/skill-writer concepts as typed related entities, not one ambiguous run type. +- Managed skill lifecycle: evidence→candidate→validation/eval→policy decision→autonomous materialization→injection/use→outcome→autonomous revision/recovery/archive. +- Managed memory lifecycle uses the same product spine while preserving fact-specific trust/conflict/supersession/deletion semantics. + +### 13.7 Observatory + +- Project × subsystem health matrix; ingest lag; rewrite/backfill/parser coverage; identity conflicts. +- Catalog/activity/project/graph/blob health; migrations; projection lag; query latency/caps/partial results. +- Doctor findings display severity, observed owner, remediation authority, evidence, and only legal actions. Foreign-owned packages are informational; the UI cannot render an update/repair button for foreign or unknown authority. +- Storage identity split is a named conflict with both safe candidates, evidence, and no initialize action; it is never rendered as “no index.” An administrator may enter the merged-#425 consolidation workflow: inspect two nonempty source identities, review path-plus-file/inode holder/freeze/reservation state and per-table/artifact dispositions, create/verify backups, produce the deterministic plan/confirmation token, start or resume the durable staging/verification/cutover operation, and copy exact recovery. The UI never accepts arbitrary raw paths, performs client-side merge logic, or starts consolidation from Settings. +- Store consolidation is operational administration, visually and permission-wise separate from Evolution/curation. It may require confirmation, pause on open holders or failed verification, and expose rollback/recovery receipts. Autonomous memory/fact/managed-skill/profile curation retains no per-item preview/apply/rollback queue and cannot invoke consolidation. +- Provider integrations show `Detected/Installed/Configured/Healthy/Degraded/Partial/Unsupported/ForeignOwned` with hook/tool/session coverage, missing pieces, last verification, and repair owner. Provider branding never substitutes for health evidence. +- Daemon/update rows show lease epoch, accepting/draining/stopped state, in-flight counts, durable progress/receipt, takeover/recovery, and safe retry; process exit alone never renders upgrade success. +- Hook/hint/tool opportunity, emitted, adopted, missed, human-corrected, unresolved and terminal-outcome metrics with denominators/horizons. +- Generated Capability Registry for every current use case and MCP/CLI/HTTP/dashboard/skill/hook binding: semantic version, request/result schema, read/mutate/autonomous/confirmation/recovery mode, scope, privacy, cost, local/live/joined evidence, availability/gap, catalog digest, and “open guided action.” Old curation approval/apply names remain operator-only migration evidence, never current help/hints/catalog. +- Storage growth, blob integrity/GC, retention, redaction/privacy, remote freshness, malformed rows. +- Provider/project/domain coverage matrix and direct drill-down to evidence. + +### 13.8 Costs + +- Tokens, latency, model/provider/tool usage, context/compression, dollar cost, estimated savings, and methodology. +- Preserve `actual`, `tokenized`, `estimated`, `mixed`, unknown model, price source/freshness/offline, recording gate, session ledger, model/day aggregates, and legacy lifetime counters. +- Every aggregate drills to sessions/Turns/messages/tools/hints/outcomes and declares confidence/missing denominator. + +### 13.9 Privacy + +- Privacy Observatory consumes `PrivacyProtectionStatusV1`: configured policy, effective non-disableable floor, source/sink/detector coverage and versions, last verified scan, sanitized/quarantined/legacy-unscanned/unknown counts, and restore eligibility. It never derives “enabled” from historical lossy rows. +- The primary artifact is a source × sink × privacy-domain coverage matrix synchronized with safe finding-class/state counts and descendant remediation lineage. Unknown/locked/corrupt/skipped coverage remains visible and prevents a clean claim. +- Findings show opaque ID, broad class/confidence/state, safe source/sink class, age, remediation/rotation state, and legal actions. No candidate, substring, length, plaintext hash, exact span, secret fingerprint, or raw field path is rendered. +- Scan/remediation/quarantine actions use their generated operation-specific inspect/plan/start/status/verify/hold/release commands and elevated authorization. Rotation/revocation is presented before deletion; restore remains blocked until isolated scan/rebuild/promotion receipts pass. +- The named current gaps—Hermes projection-only ingest, duplicated full-command hook analytics, unscanned bounded MCP failures/summaries, direct response-handle/backup copies, raw unauthenticated dashboard exposure, memory metadata/V11 vectors, and false status inference—each have an inspectable safe regression row. + +## 14.

Each chart title states the question and data interval, not a vague noun such as “Insights.” + +### 15.3 Stable layout contract + +`layout-cache.ts` keys positions by `(snapshotId, queryFingerprint, lens, layoutAlgorithm, layoutVersion, seed)`. Server-provided cluster anchors win; existing nodes keep positions during expansion; new nodes begin at the parent boundary and settle without moving unaffected clusters. A saved camera references the same key and is discarded with an explicit notice on incompatible layout version. + +- Force layout runs in a worker and stops at deterministic iteration/energy limits; it never depends on wall-clock frame count. +- Reduced motion uses the final deterministic coordinates immediately. +- ELK options, community detection, bundling, sampling, and aggregation versions are returned and shown in inspector/export metadata. +- Direct evidence edges do not bundle. Aggregate edges may bundle only when exact counts by kind/evidence remain inspectable. +- Layout workers post progressive positions within `500 ms`; main-thread tasks over `50 ms` fail the performance test. +- WebGL context loss switches to a preserved table/matrix and offers renderer restart; selection and investigation state survive. + +### 15.4 Common graph interactions + +- Click/tap commits selection; hover/focus previews without changing history. +- Shift-click pins or adds to comparison; Escape returns to the previous committed selection. +- Double-click/Enter expands one bounded neighborhood using the server cursor. +- Lasso operates only in explicit selection mode and announces count; touch uses step-through/add buttons instead. +- Path mode requires explicit source and target, legal edge kinds, max depth/cost, and at most 20 alternatives. +- Search results reveal and focus a bounded neighborhood; they do not re-run a whole-graph client filter. +- Zoom-to-fit, reset, previous/next result, parent, expand, collapse, switch fallback, and open inspector are explicit controls and keyboard commands. +- Empty-space click clears preview, not committed selection. Drag threshold prevents accidental clear. + +### 15.5 Chart rules + +- Axes have units; bars/lines carry direct labels when legible; a detached legend is supplemental. +- Unknown denominators use gaps/hatching and text, never zero-height bars. +- Partial, stale, sampled, and comparison series use the semantic ledger plus line/shape redundancy. +- Truncated axes require an explicit break marker and table values. +- Tooltips duplicate, not replace, essential values. Focus exposes the same content. +- Small multiples share scales unless a labeled independent-scale mode is required. +- Every aggregate drill-down uses the exact filter/watermark that produced it. + +## 16. Responsive, accessibility, and input behavior + +Target WCAG 2.2 AA and completion of every primary workflow by keyboard and screen reader. + +### 16.1 Keyboard and screen reader + +- One skip link each for command bar, primary view, outline, inspector, and time brush. +- Roving focus for graph outline/lane headers; DOM focus never enters thousands of Canvas marks. +- Canvas/WebGL exposes a synchronized semantic outline with selected item, visible/hidden counts, relations, and viewport summary in an `aria-live="polite"` region. +- Timeline has lane list, previous/next consequential event, next Turn, jump to time, expand noise, and read selected chain commands. +- Keyboard shortcuts are discoverable, remappable, disabled while typing, and never single-character-only without a modifier except standard spatial navigation. +- Focus is restored after route lazy-load, sheet/dialog close, inspector close, mutation result, and renderer fallback. +- Errors and coverage changes announce once; live-region announcements are coalesced to at most one per 2 seconds per region, verified with a fake-SSE burst fixture, so streaming rows cannot flood live regions. +- Tables use real headers, sort state, captions, row labels, and pagination. Virtualization preserves logical row count/position. + +### 16.2 Mobile and touch + +- All targets are at least `44×44 CSS px`; primary controls target `48 px`. +- `touch-action` and gesture ownership let the page scroll until a graph/timeline explicitly receives two-finger/pan mode. No scroll traps. +- Explicit zoom in/out/reset, previous/next, expand, collapse, and lane-step controls provide gesture alternatives. +- Portrait graph uses focused neighborhoods, not the profile topology overview. Portrait timeline shows one primary lane plus collaborator summary and step-through. +- Sheets have apply/cancel/reset, safe-area padding, focus trap, scroll restoration, and selection persistence. +- Keyboard-open viewport, 200% text zoom, orientation change, and iOS/Android browser chrome do not cover primary controls. +- Landscape graph/timeline supports a resizable inspector and maintains a minimum `320 px` evidence region. + +### 16.3 Motion and cognition + +- Respect `prefers-reduced-motion`; provide an app override but never force motion on. +- Motion explains expansion, selection, new live evidence, or time travel only; no idle pulsing/particles. +- Live additions do not steal focus or move a frozen selection. +- Use plain evidence language: “observed,” “inferred,” “temporal,” “partial,” “redacted,” “unavailable.” Avoid anthropomorphic success copy. + +## 17. Loading, empty, stale, partial, offline, privacy, and failure states + +`packages/design-system/src/states/` implements the same state vocabulary across routes: + +| State | Required presentation | Legal actions | +|---|---|---| +| Loading first snapshot | stable shell and shape skeleton, request/scope label | cancel if expensive | +| Incremental page/layout | keep existing evidence, localized progress | cancel/continue in background | +| Empty complete | exact scope/time/query/mode and evidence of complete search | clear/adjust filter, inspect source coverage | +| Empty partial | never “no data”; list unavailable/locked/redacted sources | retry, unlock, change scope | +| Stale | last-known-good timestamp/watermark and reason | refresh; read-only navigation | +| Partial | missing source matrix, effect on claim/aggregate | inspect coverage, exclude/refresh source | +| Offline | last-known-good snapshot, commands disabled | retry when online; export cached nonsensitive metadata if allowed | +| Locked | metadata/coverage only, no payload/search leak | unlock profile/store | +| Redacted | redaction class/reason and count without hidden IDs/content | request authorized view if policy permits | +| Incompatible | client/server/schema versions and supported recovery | restart/update/open current route; never stale-name fallback | +| Query budget/deadline | partial results plus operator/cost/truncation | narrow scope, raise authorized budget | +| Fatal renderer | preserve table/outline and state | restart renderer, report diagnostics | +| Fatal route/API | stable error code/request ID, no secret detail | retry, diagnostics, navigate back | + +The first-scan Brain claim is suppressed when coverage is insufficient to support it; the UI instead selects the coverage issue. Cached content disappears immediately when retention/access events invalidate it. + +### 17.1 Privacy and security + +- Use no third-party analytics, CDN, external font, telemetry pixel, or remote visualization service. +- Reject non-loopback launch/bind configuration in the first V2 default. Browser bootstrap exchanges a one-time launch nonce for an `HttpOnly`, `SameSite=Strict` session; the nonce never persists in URL/history/storage/logs. +- Send cookies with `credentials: "same-origin"`. Unsafe cookie-authenticated requests include the in-memory `X-TraceDecay-CSRF` token; logout/profile lock clears it. Nonbrowser clients use bearer auth, never a query token. +- Enforce exact loopback `Host`, exact same-origin `Origin`/fetch metadata, no wildcard CORS, and restrictive nonce CSP without `unsafe-eval`; reject forwarded-host and DNS-rebinding variants. +- Never put raw prompts, queries, file paths, branches classified sensitive, payload text, tokens, or error bodies in `console`, performance marks, route names, DOM data attributes, query keys, or screenshot filenames. +- Search and code/message payloads render text, never unsanitized HTML. Markdown uses an allowlist and strips raw HTML/URLs not explicitly safe. +- Generated view types expose content only as plan 18 sink-eligible wrappers or explicit redacted/denied/unknown variants. Feature code cannot cast raw JSON/metadata/error bodies to a renderable string; a lint/test rejects `dangerouslySetInnerHTML`, unchecked markdown/URL metadata, raw compatibility payloads, and transport error `Display` text. +- Copy/share/export previews state exactly what leaves protected storage, apply redaction, and require confirmation for payloads/reasoning. +- Clipboard deep links contain opaque IDs only. “Copy text” is a separate authorized action. +- Profile lock clears decrypted React state, CodeMirror documents, workers, Canvas text atlases, IndexedDB protected cache, and clipboard warnings; metadata may remain only if policy allows. +- Reasoning is opt-in, excluded from search/export by default, and always carries format/visibility/retention labels. +- Deletion previews show descendant projections/blobs/FTS/vector impact, holds, recovery grace, and non-content audit receipt before confirmation. +- The V1 arbitrary-host/unauthenticated raw dashboard seam is a mandatory negative fixture: first-default startup rejects non-loopback bind, every API view authenticates, and no raw content/metadata path survives V2 route cutover. + +## 18. Deterministic export and visual QA + +Interactive Canvas/WebGL state is never screenshot directly as the only export. `packages/renderers/src/export-scene.ts` builds a separate frozen scene from: + +- exact query/snapshot/vector watermark and retention watermark; +- fixed viewport, DPR, font files, locale/time zone, layout seed/version, color theme; +- explicit selection, scope/time/query fingerprint, transcript mode, hidden/sampled counts, coverage and redaction report; +- static labels, axes, relationship/evidence key, caveats, and no hover-only content. + +Export waits for `render-ready` after fonts/layout/data settle. It rejects if a live snapshot changes, then offers freeze-and-retry. WebGL export falls back to SVG/table/server rendering on unsupported context or size. JSON/Markdown/SVG/PNG exports share one manifest; canonical JSONL/Parquet remain server export formats. + +Visual fixtures use a committed redacted corpus, fixed UTC time, fixed fonts, fixed random/layout seeds, and desktop `1440×1000`, laptop `1280×800`, mobile portrait `390×844`, mobile landscape `844×390`, and 200% text zoom. Each feature PR: + +1. captures accepted concept and latest browser screenshot at matching dimensions; +2. uses `view_image` on both in the same QA pass; +3. records at least five comparisons across copy, layout, typography, palette, icon/mark semantics, spacing/container, responsive behavior, or motion; +4. updates `dashboard/design/fidelity-ledger.md` with mismatch and fix; +5. fails on unapproved visible copy, generic substituted icons, clipped content, overflow, unreadable chart text, empty Canvas, or concept drift. + +A mismatch is **material** — and must be fixed or explicitly waived with rationale in the fidelity ledger — when it changes copy text, changes a semantic color/mark meaning from the section 2.3 ledger, adds or removes a UI element, breaks the stated screen anatomy (section 2.2), or shifts spacing/alignment by more than `8 px` at `1440×1000`. Anything below those thresholds is recordable but non-blocking; the reviewer applies the threshold list, not taste. + +Manual browser QA uses the in-app Browser first. Playwright Chromium/WebKit/Firefox supplies repeatable CI and mobile emulation, not visual taste approval. + +## 19. Performance budgets and degradation + +Record reference machine, corpus manifest, build mode, browser/GPU, viewport, and five-run median/p95.

A generated migration inventory owns every legacy surface. Typed route modes select one effect owner per bounded context, V1 adapters exist only while that context is pre-cutover or during an explicit operator rollback, shadow comparators use frozen vector watermarks, and signed cutover receipts make data migration reversible. There is no live fallback for stale clients, protocols, plugins, or tool names.

Root composition wires their adapters, exactly one scheduler/lease authority, migrations, cutovers, and deletion receipts; it owns none of their semantics. +- Plan 10 owns HTTP V2, SSE, authentication, OpenAPI, and generated clients. +- Plan 11 owns the new frontend and legacy-dashboard view/action parity. +- Plans 13–24 own durable research anchors, historical regressions, retrieval evaluation, cross-project scope, the official public API/SDK declaration, mandatory sanitizer/privacy, unified configuration, exhaustive CLI/MCP/output, incremental context scouting, temporal session/LCM retrieval, and canonical task/plan/multi-agent execution. Root composes their ports, lifecycle, packages, and cutovers; it does not fork their contracts. +- This plan owns only root composition, V1 compatibility adapters, process lifecycle, CLI/MCP/legacy HTTP bindings, provider installation, upgrade/release, migration orchestration, and final V1 code/store retirement. +- Plan 20 owns configuration registry/resolver/history/impact semantics. Root inventories and imports every V1 file, flag, environment read, provider/hook/daemon setting, and dashboard mutation, then deletes all live legacy readers after generated config bindings pass parity. +- Plan 21 owns binding/output semantics. Root supplies thin generated Clap/MCP adapters, stdout/stderr/exit and protocol framing, then deletes handwritten schemas/dispatch allowlists/renderers/aliases after parity; it cannot keep a root-local catalog or error model. +- Plan 22 owns scout workflow/model-gateway/host-delivery semantics. Root supplies daemon scheduling, optional App Server adapter, and host handshake wiring without putting model/search work on the hook path. +- Plan 23 owns temporal message/LCM search and context semantics. Root supplies V1 import/shadow adapters and generated bindings, then deletes independent legacy FTS/LCM/ranking/load-routing paths after cutover. +- Plan 25 owns `tracedecay-code-index`. Root composes its producer with the projector-owned build port and daemon watcher, but neither projectors nor application imports the production indexer. +- Plan 26 owns accounting/observability contracts, projections, metric registry, and SLO semantics.

Goals + +- Keep `tracedecay` as one installable command and one current-version MCP/daemon identity throughout the rewrite; incompatible running processes must restart rather than degrade. +- Resolve profile/privacy domain, configuration, runtime identity, and route/catalog generation once at process bootstrap. Preserve invocation CWD/host facts in `RequestContext`; each request's exact domain `ScopeSelectorV2` is authorized/resolved by the application service, so a long-lived process never pins the first project/worktree/branch as global scope. +- Give each process only the services it needs: a hook does not open the dashboard/query graph; a one-shot read does not start writers; the daemon owns long-lived writers/workers. +- Inventory every CLI command/flag/output, MCP tool/schema/renderer, HTTP route/action, dashboard behavior, config/env/default, hook/provider event, database/sidecar, installer mutation, doctor/repair, and release behavior before moving it. +- Preserve V1 external behavior only while its bounded context is V1-authoritative or in non-effecting shadow; at cutover, current clients switch atomically to V2 and stale clients fail closed. Keep V1 stores read-only for one full release solely for verified data rollback/archive. +- Ensure one canonical effect owner at all times. Shadow execution may compare results but may not inject a second hint, advance a second source head, apply a second mutation, or launch a second automation run. +- Backfill from read-only V1 sources, compare at fixed watermarks, cut over by bounded context, and roll back by route/lease changes without deleting V2 evidence. +- Make migration resumable, private, hash-manifested, observable, and explicit about every input's disposition — `retained`, `skipped` (with reason `corrupt`, `ambiguous`, or `unavailable`), `quarantined`, `redacted`, or `deleted` — using the Section 14.1 per-entity manifest schema. +- Split `src/global_db.rs`, `src/mcp/server.rs`, `src/mcp/tools/definitions.rs`, `src/sessions/lcm/query.rs`, `src/agents/mod.rs`, and other giant modules by deleting migrated responsibilities, not by copying them into new monoliths. +- Preserve agent host install/update/uninstall semantics, safe config merge/backups, plugin manifests, daemon service management, self-update, release assets, and package installation. +- Make an older binary, running daemon/MCP process, plugin protocol, or stale tool name fail before service/store use with an exact restart/update/current-replacement error; it must never downgrade, silently fall back, or corrupt a store. +- Publish privacy-safe advisory `AgentPresence`, `WorkClaim`, acknowledgement, handoff, and release evidence from every supported host/worktree, with stable session/agent/goal/retrieval anchors and bounded TTL; never mirror full prompts or turn coordination into a lock. + +## 3. Non-goals + +- No business rules, canonical IDs, query AST, ranking, projection semantics, policy VM, SQL schema, HTTP envelope, or UI state in root composition. +- No flag-day switch, writable V1 importer, bidirectional database replication, distributed transaction, or implicit cross-profile merge. +- No irreversible representative-message dedupe. PR #410 views remain query-time/projection semantics over complete sanitized native observations, lossless for retained non-secret structure/semantics. +- No resurrection of Hermes-specific runtime profiles, bridges, config projections, pending-skill inventories, or dashboard ownership removed by PR #407. +- No automatic deletion of legacy stores during upgrade, migration, V2 defaulting, rollback-window closure, or uninstall. +- No inference that `tracedecay.db` is disposable code-index cache. It currently contains graph-resident durable memory/fact tables; code-graph parity alone can never authorize deletion. +- No remote GitHub writes from the first V2 investigation product. Existing Git/PR reads and local semantic tools remain available with explicit freshness. +- No public stability promise for internal V2 implementation crates beyond what the root package requires; their exact-version release contract is specified in Section 16. +- No live compatibility fallback for old running MCP/daemon/plugin clients, stale protocol/catalog generations, retired tool names, or renamed arguments. Required data migration and read-only archive rollback are separate operator workflows in the current binary. +- No distributed work scheduler or mandatory claim enforcement. Presence and claims help agents coordinate and can be acknowledged/handed off, but they never authorize, deny, reserve, or prove causation. + +## 4.

PR 3R additionally emits a file-level path/glob appendix for every family in the generated inventory, so store completeness is auditable against the tree before the migration controller exists. For the Hermes kanban family the appendix enumerates the per-board glob `/kanban/boards/*/kanban.db` and the default `/kanban/kanban.db`, each board DB's `tasks`, `task_links`, `task_runs`, `task_events`, `task_comments`, `task_attachments`, and `kanban_notify_subs` tables, and the `-wal`/`-shm` sidecars, so no board is silently omitted before the plan 24 mapping runs. + +After a source-family capture cutover, V2 is the only canonical source-offset owner.

Product reads cannot become V2-default before their required projections/query/application routes are V2-authoritative. All long-running processes pin its protocol/catalog generation and terminate/restart when it changes incompatibly. +- Shadow calls receive the same normalized request and captured time/vector watermark. A live drift marker is not a parity mismatch. +- Read shadow may execute both paths.

Comparison classes describe shadow parity results only; per-entity backfill accounting uses the Section 14.1 disposition vocabulary. +- A cutover receipt (`CutoverReceiptV1`, allocated in the `ManifestId` space; plan 19 §12.2 step 5 records this same schema) records binary/commit, V1 inventory and store manifests, V2 schema/registry/catalog/policy/projector digests, source/vector watermarks, counts/hashes, accepted differences, feature route, lease epochs, backup, tested rollback, the plan 18 PR 33A retroactive-privacy-audit remediation/restore-eligibility receipt for the context (zero synthetic canary hits), and the plan 14 `FM-###` rows whose gates the cutover satisfies. +- Route publication uses stage -> validate -> fsync -> atomic rename/CAS generation. Every process rejects a partial or digest-mismatched route set. +- At V2 cutover, V1 public routing and stale tool/protocol bindings are removed atomically. A stale client receives a typed `client_update_required`, `daemon_restart_required`, or `capability_replaced{current_binding}` error from plan 17's stale-client error-code registry, naming the current replacement; the server never executes a legacy alias or opens V1 on its behalf. +- Before PR 36 only, rollback is an explicit current-binary operator workflow: quiesce all processes under the lifecycle lease, fence V2 writers/effect owners, restore the V1 source position/owner recorded by the receipt, publish one lower route generation, restart current clients, and retain V2 evidence read-only. It is not an always-on fallback. +- After PR 36, rollback means a prior compatible V2 binary/schema or restore/reimport of non-disposable data into V2. The read-only V1 archive protects source data and evidence but can never be re-enabled as a live transport/store owner. Its expiry controls physical deletion, not protocol compatibility. + +**Receipt signing.** “Signed” means HMAC-SHA-256 with a profile-local signing key stored in the profile catalog (`catalog.db` key table: `key_id` primary key, OS-protected key-material reference, `created_at`, `retired_at`), not asymmetric PKI. Every receipt, route snapshot, and rollback record carries its `key_id`; rotation is a typed operator command that mints a new key and retains retired keys for verification until every artifact referencing them is superseded or archived. Route load re-verifies the HMAC before use; verification failure is a typed fail-closed error that rejects the entire route set. Plan 19's signed inventories/receipts reuse this mechanism by reference. + +**Rollback drill record.** Every drill and every real rollback writes a `RollbackDrillRecordV1`: + +- `drill_id: ManifestId` — primary key; +- `context: BoundedContext` and `receipt_id: ManifestId` — the `CutoverReceiptV1` exercised; +- `is_drill: bool` — real rollbacks record `false`; +- `restored_watermark: VectorWatermark` and `epoch_fence_evidence` — pre/post fenced lease epochs proving no stale writer survived; +- `started_at`/`completed_at` timestamps and measured downtime; +- `data_difference: none | expected_normalization | unexplained` — `unexplained` blocks the gate; +- operator principal and signing `key_id`. + +Uniqueness `(context, receipt_id, started_at)`; indexes on `(context, is_drill)` and `receipt_id`; one row per drill/rollback, stored in the profile catalog migration-receipt tables beside the receipt it exercises and retained until that receipt's archive window closes. A gate requiring a “tested rollback” is satisfied only by a matching `RollbackDrillRecordV1` with `data_difference != unexplained`. + +## 10. Configuration, Environment, Profile, and Runtime Identity + +PR 3R inventories every field/default/source from `TraceDecayConfig`, `SyncConfig`, `TelemetryConfig`, `UserConfig`, Clap, provider templates, and environment access.

Defaults remain V1 until a signed receipt exists. +- Emergency environment overrides are limited to operational tuning and diagnostics — timeouts, log verbosity, socket/path selection, offline mode, and read-only diagnostic modes. They cannot select V1 or V2 routing. Rollback requires the typed operator command, lifecycle lease, signed receipt, quiescence, and process restart; environment drift cannot bypass migration gates. +- Profile selection happens before global/catalog/store opens. PR #407 means Hermes commands/sources use the same active profile. +- Every client/daemon/plugin handshake exchanges exact root build/protocol version, route generation, schema major, catalog digest, tool-catalog generation, and profile identity. Any mismatch that changes executable bindings rejects the connection before request/store use and reports restart/update/current replacement; there is no older-reader or stale-plugin mode. +- Ordinary configuration patches are direct application commands with inline full-snapshot validation/impact, expected revision, idempotency, atomic private write, backup, audit event, and typed restart/operation requirement. They have no generic preview/apply ceremony. Separately cataloged destructive system effects use an operation-specific inspect or immutable plan followed by separately authorized start. Root adapters never directly mutate config from HTTP/MCP. +- Existing host-owned config file semantics—JSON, JSONC, TOML, shell hook, permissions, backup/restore, unrelated-key preservation—remain installer responsibilities and have fixture parity. + +## 11.

It coordinated whole-plan reviews, cross-plan arbitration, and pinned Hermes backend/frontend research. The supported TraceDecay session lookup was attempted first but stopped at the preserved selected-versus-legacy project-identity conflict; the bounded fallback is the provider-local main JSONL and its `subagents/` directory under `/home/zack/.claude/projects/-fast-projects-tracedecay--claude-worktrees-nice-sanderson-dc67f1/`.

The three independent Codex audits of all 39 child JSONLs plus the main session recorded complete ranges and compared conclusions to plans 00–26. They found the late Hermes task/dashboard/store/model-artifact editors stopped on a concurrent edit or Claude monthly spend limit; their unfinished requirements were subsequently integrated into plans 01/02/05/09/11/12/14/20/21/22/24/26. Do not infer “completed” from the presence of a child file—retain interrupted/spend-limit terminal status. + +Implementation must replace these local locators with durable `RetrievalAnchorId`s whose target is the main session or exact subagent transcript span, including source identity, provider-native child ID, branch/worktree, occurred/ingested range, access/privacy digest, and the plan/artifact relation. A future agent should be able to resolve “who researched this decision?” from a plan section to the exact authorized audit context without copying private text into Git. + +### 4.2B Final reconciliation-wave attribution + +The final Codex reconciliation wave remains under parent session `019f4906-a411-7a11-ad3f-0d58deb0e847` and parent task path `/root`. The orchestrator exposed the following canonical task paths and bounded artifact scopes during the wave: + +| Canonical task path | Bounded contribution/artifact evidence | Attribution status | +|---|---|---| +| `/root` | Lead arbitration, shared-diff review, current Git/PR refresh, verification, commit, push, and draft-PR update. | Parent provider session observed; exact lead Turns remain resolvable through the parent session. | +| `/root/fix_product_surface_contracts` | Reconciled Brain/UI, public API, search-evaluation, saved-view, configuration, and product-surface contracts across plans 09/10/11/13/15/17/23. | Canonical orchestration task path plus bounded artifact/diff result; no durable child provider-session ID was exposed. | +| `/root/fix_task_executor_contracts` | Reconciled task offers, atomic admission, assignments, leases, packets, executor lifecycle, manual-work commands, views, and orchestration parity in plan 24. | Canonical orchestration task path plus bounded artifact/diff result; no durable child provider-session ID was exposed. | +| `/root/fix_code_accounting_contracts` | Reconciled code-index generation identity/ownership and normalized accounting/metric dimensions in plans 25 and 26. | Canonical orchestration task path plus bounded artifact/diff result; no durable child provider-session ID was exposed. | +| `/root/centralize_baselines_deslop` | Centralized stale publication snapshots and removed obsolete skill-header references across its assigned plan files. | Canonical orchestration task path plus bounded artifact/diff result; no durable child provider-session ID was exposed. | +| `/root/release_dag_ownership` | Reconciled release/ownership DAGs and crate/client ownership in plans 01, 12, and 19. | Canonical orchestration task path plus bounded artifact/diff result; no durable child provider-session ID was exposed. | +| `/root/cross_plan_gap_deslop_audit` | Independent cross-plan retrieval-surface and plan-quality audit; findings were routed to the lead for owned-file correction. | Canonical orchestration task path plus reported audit result; no durable child provider-session ID was exposed. | +| `/root/redesign_mcp_surface` | Designed the first-class MCP surface in plans 08/21, reconciled retrieval-operation consistency, then refreshed the private chronological corpus and this provenance plan with current hashes, master/PR state, and attribution gaps. | Canonical orchestration task path plus bounded artifact/diff result; no durable child provider-session ID was exposed. | + +This is deliberately weaker than provider-native child attribution. `sessions_for(git_ref="worktree", value="/fast/projects/tracedecay/.worktrees/codex-tracedecay-total-redesign-plan")` returned zero after the parent session became loadable, and raw patch/edit events do not carry durable task-path or child-session linkage. Therefore the task paths above are orchestration retrieval IDs and artifact claims, not proof that a specific provider child authored each changed line. Preserve this as an `AttributionGap` until V2 captures `parent_session_id`, `agent_instance_id`, canonical task path, Turn IDs, edit-event IDs, produced artifact spans, and Git observations in one causal chain. + +### 4.3 Private chronological corpus + +The corpus itself remains outside Git: + +- Manifest: `/fast/tracedecay-redesign-research/manifest.json`. +- Secret-scanned/redacted native `role=user` corpus: 34,344 rows; SHA-256 `edfe67d6baf9fd87faa9fd49c443a777bbb838c3eb36a79106c06f18a161baff`. +- Secret-scanned/redacted best-effort human subset: 9,980 rows; SHA-256 `5afb40d25f3fc43b86d620b25daea94a0b4f33ffc4421b5bb20b6a550b8c3bcb`. +- Frozen refreshed user-message cutoff: 2026-07-10 20:26:39.847 UTC. The active parent contributes 39 direct prompts with `codex_rollout_raw_fallback` provenance: the original 28-record addendum plus 11 post-cutoff prompts. Three post-cutoff internal goal/environment envelopes were excluded. +- The containing directory is mode `0700`; primary files, byte-identical retained copies, manifest, scanner reports, and helper scripts are mode `0600`. +- Per-row `content_hash` is SHA-256 of retained sanitized UTF-8 `content`, not a pre-redaction source digest; validation reports zero mismatches, zero duplicate identities, zero missing timestamps, and zero chronological violations. + +This is a private corpus reference, not a distributable PR fixture. `gitleaks 8.30.1` and parsed-value credential detectors were run; the refreshed broad and human corpora each report zero findings. Conservative redaction removed marker/credential-shaped values and examples while preserving row identity/order. An authenticated-URL alert from serialized-line scanning was rejected as a cross-field false positive after parsed-value validation. Supported LCM now resolves the exact parent, but worktree correlation still returns zero; the refresh is attributed only to parent session `019f4906-a411-7a11-ad3f-0d58deb0e847` and task path `/root`, not to guessed child agents.

Primary research and applied decisions + +- [Okapi at TREC-3 / BM25](https://www.microsoft.com/en-us/research/publication/okapi-at-trec-3/) — retain a fast, interpretable lexical baseline; identifiers, errors, paths, tool names, and quoted text strongly favor exact lexical evidence. +- [Dense Passage Retrieval](https://arxiv.org/abs/2004.04906) — evaluate dense recall for paraphrases against strong BM25; do not assume semantic superiority. +- [SPLADE v2](https://arxiv.org/abs/2109.10086) — test learned sparse expansion as an optional local semantic channel with inverted-index behavior and inspectable terms. +- [Reciprocal Rank Fusion](https://plg.uwaterloo.ca/~gvcormac/cormacksigir09-rrf.pdf) — use deterministic RRF as the first robust hybrid baseline before learned fusion. +- [Passage Re-ranking with BERT](https://arxiv.org/abs/1901.04085) — cross-encode only a bounded candidate set; measure precision gain versus latency/memory. +- [ColBERT](https://arxiv.org/abs/2004.12832) and [ColBERTv2](https://arxiv.org/abs/2112.01488) — benchmark late interaction as an optional middle point; index footprint and local inference cost are release gates. +- [Document Expansion by Query Prediction](https://arxiv.org/abs/1904.08375) — expansion may reduce vocabulary mismatch, but generated terms are versioned/explained and never quoted as source evidence. +- [ANCE](https://arxiv.org/abs/2007.00808) — mine hard negatives from real high-scoring false positives, wrong projects/times, copied prompts, and rejected results rather than random rows alone. +- [Maximal Marginal Relevance](https://aclanthology.org/X98-1025/) — diversify repeated turns/summaries/sessions while preserving distinct evidence. +- [HippoRAG](https://arxiv.org/abs/2405.14831) and [G-Retriever](https://arxiv.org/abs/2402.07630) — typed bounded graph expansion can recover multi-hop context; unrestricted GraphRAG is not the default. +- [BEIR](https://arxiv.org/abs/2104.08663) — heterogeneous domains vary materially; report project/provider/query-stratum results rather than one mean. +- [TREC relevance judgments](https://trec.nist.gov/data/reljudge_eng.html) and [pooled versus sampled judgments](https://www.nist.gov/publications/comparison-pooled-and-sampled-relevance-judgments) — pool candidates from every system and add sampled negatives to reduce evaluation bias. +- [Optimized Interleaving](https://www.microsoft.com/en-us/research/wp-content/uploads/2013/02/Radlinski_Optimized_WSDM2013.pdf.pdf) — use explicit UI interleaving only after offline/shadow safety; automatic hint contexts need stricter replay/A-B guardrails. + +## 3. Retrieval document and identity model + +Index separate typed grains instead of flattening all content into one FTS row: + +- Native message/content part and representative message cluster. +- Turn with start context, user/agent exchange, tools, visible reasoning artifacts, goal/work-claim state, and output. +- Session/thread summary with exact source ranges/coverage. +- Agent instance, goal/task/work claim, workflow run/phase/agent, and handoff. +- Git ref/commit/diff/PR/check/review/release evidence. +- Code file/symbol/snapshot/diagnostic/test/impact evidence. +- Fact/version/entity/decision/contradiction/retrieval/feedback. +- Automation job/run/artifact/proposal/skill/version/outcome. + +Every result carries a domain `RetrievalAnchorId` resolving to `RetrievalAnchorRecordV1`, plus stable canonical/native aliases, resolved `ScopeSelectorV2`/repository/worktree/ref/snapshot identity, project/profile/privacy owner, provider, occurred/ingested/valid time, origin/audience/kind, source range, representative/hidden-row membership, index/model version, evidence class, sanitization/redaction state, and coverage. Summary/embedding documents never replace source IDs or become the sole anchor. + +## 4. Versioned candidate pipeline + +### 4.1 Query understanding + +- Preserve quoted phrases, exact IDs, error text, paths, symbols, API/tool/config names, and case-sensitive literals. +- Normalize Unicode and punctuation with visible tokenizer/version. +- Resolve provider/tool/project/branch/PR/session/agent/goal aliases into candidate entities without removing original tokens. +- Detect explicit time, scope, audience/origin, result kind, exact-versus-conceptual, and no-answer intent. +- Generate optional spelling/fuzzy/expansion terms as separate explained channels; never alter quoted evidence. + +### 4.2 Recall channels + +1. Exact ID/native alias and exact phrase. +2. Field-weighted FTS5 BM25 over typed fields. +3. Character n-gram/edit-distance fuzzy channel for typos and partial identifiers. +4. Entity/event/goal/tool/Git/code indexes. +5. Agent/session/work-claim/relation graph seeds and bounded typed expansion. +6. Summary DAG documents with source coverage and retained-time limits. +7. Optional privacy-domain local dense representation. +8. Optional learned-sparse/SPLADE representation. +9. Explicit recency/time-distance feature only when query/time profile warrants it. +10. Temporal-assertion/current-state index channel for session-temporal intents (specified in plan 23 §5.2; executed by plan 05's `session/temporal_resolver.rs`). +11. Explicit recent-activity listing channel for listing intents only — the `list_sessions`/`list_messages` list intents defined in plan 05 §6.2. + +Each channel returns a bounded candidate list with channel rank/score, matching fields/terms/entities, index watermark, truncation, and latency. + +### 4.3 Fusion, noise control, and diversity + +- Start with the fusion contract defined once in plan 05 §11.3: deterministic RRF over declared channels within each shard, then the calibrated cross-shard merge with exact-match tiers first. Plan 05 owns byte determinism for a fixed layout and bounded repartition-drift tests (exact-match-tier invariance plus locked top-k-overlap/nDCG floors with explanations), not impossible byte-identical output after arbitrary repartition. Learned fusion is a later ablation requiring feature/version explanation. +- Cluster copied parent prompts, provider protocol/tool echoes, same-content cross-store rows, summary/source lineage, and repeated assistant status messages. +- Select representative by requested audience/origin/kind and evidence quality; report hidden counts and exact sanitized-native expansion. +- Penalize the active query/tool command echo, inventory listings, protocol notifications, and same-session repetition unless requested explicitly. +- Preserve exact identifier/phrase hits before semantic diversification. +- Apply bounded MMR/session-project-provider-agent diversity so ten near-identical children do not occupy the page. +- Use typed project/time/privacy constraints before ranking; do not ask a reranker to repair unsafe scope. + +### 4.4 Bounded reranking + +- Compare no reranker, local cross-encoder, and ColBERT-style late interaction over a fixed top-N pool. +- Inputs include query, typed result grain, safe content slice, entity/evidence features, time/scope, and cluster metadata. +- Secret-classified or locked content uses lexical/entity-only mode unless an explicitly authorized local model/index exists in the same privacy domain. +- Missing model or timeout falls back to the declared pre-rerank order with reason; it never returns a silently shorter set. + +### 4.5 Bounded graph expansion + +- Expand only high-confidence lexical/semantic/entity seeds. +- Legal relation kinds, direction, evidence class, confidence floor, time window, depth, node/edge budget, and privacy frontier are explicit. +- Multi-hop results explain the path. A graph neighbor is not relevant merely because it is connected. +- Agent proximity uses current `AgentPresence`/`WorkClaim`; historical search uses versioned events, not live state. + +## 5. Real local multi-project evaluation corpus + +The private qrel store belongs to the active profile and is never committed. A redacted/synthetic subset plus aggregate metrics is checked in. + +The frozen research corpus this program draws on is pinned by its owner, plan [`13-research-provenance-and-context-anchors.md`](13-research-provenance-and-context-anchors.md): path set `/fast/tracedecay-redesign-research/*`, file mode `0600`, final user-message cutoff `2026-07-10T02:21:15.411Z`, integrity verified against plan 13's manifest hashes. The manifest distinguishes the broad supported-surface capture from the 28-record active-session raw-rollout fallback. Evaluation inputs derived from it cite that manifest, and no private content from it enters the repository. + +### 5.1 Query sources + +- Actual later human prompts that refer to an earlier issue, plan, session, PR, worktree, decision, fact, tool, or agent. +- Explicit “find/recall/show/go back to” requests and later corrections when the wrong session/project was returned. +- Search reformulations and abandoned queries. +- Successful retrieval-to-action sequences where the user/agent opened an anchor and continued relevant work. +- Agent duplication/coordination cases, branch/PR context, diagnostics, memory, automation, hints, provider integration, dashboard, and release incidents. +- Synthetic/adversarial variants: misspellings, abbreviations, renamed projects, old aliases, exact error/API strings, paraphrase, negation, expected no result, wrong-project near match, wrong-time superseded evidence. + +For a query at time `t`, the candidate corpus is frozen to records whose allowed ingest/observation cutoff is `< t`. Later messages, summaries, labels, branches, or outcomes cannot leak into retrieval features. + +### 5.2 Strata and holdouts + +- Every registered project with sufficient data; small projects are grouped only for reporting, not omitted silently. +- Codex, Claude, Cursor, Hermes, and other supported provider families. +- Human/direct-user, subagent/delegated, assistant, tool-result, provider-protocol, summary, and unknown origin. +- Exact identifier/literal, phrase, typo, conceptual/paraphrase, temporal, cross-project, multi-hop, Git/PR, code/symbol, memory/fact, automation/skill, hint/tool-routing, nearby-agent, and no-result query. +- Recent versus old evidence, short versus long content, single versus many candidate sessions, healthy versus partial/retained/locked shard. + +Use chronological train/dev/test splits plus full holdout of selected projects, providers, and later time blocks. Frozen test judgments are never used to tune weights, prompts, expansion, models, or thresholds. + +### 5.3 Candidate pooling and hard negatives + +- Pool top 20 from current search, exact/BM25, fuzzy, dense, learned sparse, RRF, graph, expansion, late-interaction, and cross-encoder variants. +- Add stratified random candidates to reduce pooling bias. +- Add hard negatives: same terms/wrong project, same project/wrong time, copied child prompt, current query/tool echo, superseded fact, observed-not-produced commit, nearby but disjoint agent, stale summary, protocol row, and same title/different session. +- Version the pool. New systems add candidates and new judgments without rewriting prior qrels. + +### 5.4 Judgment contract + +Label each query-result pair: + +- `0 misleading_or_irrelevant`. +- `1 topical_but_not_actionable`. +- `2 useful_context`. +- `3 decisive_or_smallest_sufficient_anchor`. + +Also label duplicate/echo/protocol noise, wrong project/provider/time/origin, stale/superseded, privacy-ineligible, relation/evidence requirement, and whether the result enables the next action. Record the smallest sufficient anchor grain: message, Turn, session, agent, goal, work claim, workflow, commit/PR, fact, code entity, or evidence bundle. + +A substantial stratified subset is independently double-labeled. Report raw agreement and an ordinal agreement statistic; adjudicate disagreement while retaining both labels/rationales. Ambiguous cases remain distributions/unknown, not forced truth. + +The judgment record is concrete, not deferred.

Offline, shadow, and online evaluation + +### 7.1 Frozen offline gates + +- Current production search is baseline A. +- Fielded BM25/phrase/origin filtering is baseline B. +- Every added channel has an ablation and resource profile. +- Exact ID and exact phrase Precision@1/Recall cannot regress beyond an explicitly reviewed case. +- Candidate default must improve predeclared Precision@3, nDCG@10, first-useful rank, and duplicate rate on dev and untouched test, with no material worst-stratum/privacy/no-answer regression. +- Gates are calibrated on frozen development data, then locked before test evaluation; no absolute corpus-independent nDCG/recall floor is pre-committed. Plans 05 §11.3/§17, 06, 23 §8.6, and the master gate list cite this regime. +- **Material worst-stratum regression, numeric definition (cited by every other plan):** a worst-stratum nDCG@10 drop greater than `max(2 points absolute, 5% relative)` versus the locked baseline, or any no-answer-precision drop greater than 2 points. +- **Promotion evidence minimums (this plan owns the shared corpus; matching plan 23 §8.2, the regression matrix, and the master gates):** at least 500 real query episodes, and candidate pools plus manual labels sufficient for at least 5,000 human-grounded judgments, with independent double labels on at least 20% of judgments. A promotion claim on a smaller corpus is invalid regardless of scores. + +### 7.2 Rolling local evaluation + +- Maintain frozen regression, rolling recent, project holdout, provider holdout, temporal holdout, and adversarial typo/identifier/no-result sets. +- Mine hard negatives from opened-then-rejected results, reformulations, ignored/incorrect hints, explicit corrections, duplicate sessions, wrong project/time, and newer evidence that superseded a stale result. +- Refresh rolling sets under versioned cutoff; never edit frozen judgments to improve a score. + +### 7.3 Shadow evidence + +- Candidate rankers run against real eligible queries without changing delivered results/context. +- Store ranked stable IDs, explanations, resource cost, and coverage—not sensitive query text in analytics. +- Compare chosen/expanded/loaded anchors, later actions, reformulation, abandonment, and corrections as weak evidence requiring calibration/manual judgment. + +### 7.4 Controlled online comparison + +- Randomized interleaving is allowed only in explicit Search/Explorer UI with opt-in telemetry and reversible assignment. +- Automatic hook/hint retrieval uses historical replay and shadow first, then a narrow A/B with strict relevance/repetition/token/latency/correction guardrails. +- Never explore aggressively inside agent prompts or silently change the historical context of an in-progress workflow. +- Helpful/unhelpful labels and result actions are feedback events, not direct training truth. + +## 8.

Untracked branch graphs and divergent session variants are first-class identities; consolidation uses bounded indexed family lookups; registry healing cannot steal aliases/paths or resurrect retired owners; search reads never repair; graph peers disable mmap; applied-manifest retirement is restart-safe and lifecycle-fenced. Historical failed explicit-worktree/root PR context, zero-file search, and branch/session lookup remain required cross-domain partial/fallback fixtures. + +## 1. Product invariant + +An agent or person must be able to ask one question about one named repository, several related repositories, every registered project, a particular worktree, or a historical ref and receive: + +1. Results from the intended scopes, never a silent fallback to the active checkout. +2. One stable identity for every repository, checkout, worktree, ref snapshot, session, message, agent, and code entity. +3. Explicit coverage: searched, skipped, unavailable, stale, truncated, redacted, and permission-denied scopes, carried as one typed record — plan 01's `CoverageReportV1` (shard dispositions, freshness watermarks, unknown-coverage flag) — rather than per-transport prose. +4. A direct retrieval path from a summary/search hit to the exact underlying object, even when the object lives in another project shard. +5. The same selector, error, cursor, and response semantics in the official API, CLI, MCP, dashboard, hooks, and generated SDKs. +6. A compact answer by default and full provenance on demand. +7. Plan 22's Context Scout may expand across projects only through a pinned authorized project-set version; a model cannot turn current scope into All, and sibling task/agent activity is silent without a material typed relation. +8. Plan 23's temporal search and context assembly use the same resolved scope before ranking and return stable cross-shard anchors; current/as-of logic cannot repair a wrong project/worktree/ref after retrieval. +9. Plan 24's initiative/plan/work-item graph pins one authorized project-set version and exactly one writable workspace binding per attempt. Other repositories are read-only; a required multi-repository write decomposes into one fenced child work item per writable target plus explicit integration gates. A board, executor, agent, CWD, current checkout, or task title cannot add a repository, change the primary writable worktree/ref/snapshot, or copy a task to repair scope after dispatch. + +“Current project” remains a convenient default. It is never an invisible constraint and never overrides an explicit repository, worktree, path, PR, branch, session, or agent reference in the request. + +## 2. Historical evidence and exact anchors + +The following sessions are regression fixtures, not anecdotes: + +| Retrieval anchor | Observed behavior | Required regression | +|---|---|---| +| `session:019f42c9-623a-7cc0-95c1-f073eaa05a4d` | An agent concluded that TraceDecay had no registered Rsbuild/Rspack sibling project and fell back to installed package sources. | A multi-token resolver and related-project suggestion must find both repositories or return disambiguated candidates; it must not equate one failed search string with registry absence. | +| `session:019f4323-f569-74c0-9988-ea3851d14fd7` | The user corrected the agent: Rsbuild and Rspack were in the registry. `project_list` was initially capped at 25, `project_search "rsbuild rspack"` returned none, and the agent needed separate searches before querying both graphs. | One request resolves a project set and executes the intended federated code query; caps and omitted projects are explicit; no manual list-then-filter loop. | +| `session:019f4325-57ef-7a53-b6a0-5c583c759301` | Root-cause analysis found project search used one contiguous `LIKE "%rsbuild rspack%"` pattern rather than token-aware matching. | Exact, token, alias, remote, path, fuzzy, and relationship-aware resolution are separately evaluated and explained. | +| `session:019efb4d-4508-7182-961b-9b30c739baa7` | Earlier React Router plugin work found Rspack but reported Rsbuild unregistered, then mixed a sibling graph with local installed-package inspection. | Results identify source repository, snapshot, and fallback provenance per evidence item; missing one related repo does not silently change evidence class. | +| `session:019f1568-f9de-75c1-9870-7cee46944adc` | A copied/recovered workflow repeated the same partial cross-project conclusion. | Copied workflow/session results cluster under the canonical investigation and do not inflate confidence or evaluation counts. | +| `session:3277c0dd-4388-4a99-9665-96eefe31918a` | A natural-language request for a nearby Rsbuild React Router repository succeeded only after separate registry queries. | `resolve_scope` accepts natural language, returns the dedicated repository directly, and offers adjacent Rsbuild/Rspack/React Router scopes as optional related context. | +| `session:f6e02b68-dcb8-4fd4-975e-9ad5895d2a9d` | A contamination investigation had to prove that separate registered repositories used separate stores and that an incorrect “federation” theory came from the model rather than TraceDecay. | Every result exposes store/project/repository identity and evidence origin; the system can prove cross-store isolation without raw database inspection. | +| `session:019f3edc-6a4e-7d80-b181-8f6d1e657859` | PR context resolved the base checkout/branch while the user intended a different worktree. | Worktree and ref snapshot are first-class selectors; a branch-sensitive operation refuses an ambiguous active/base mismatch. | +| `session:019f2538-0fd9-7362-a50b-96e36130643b` | Session search remained constrained through `sessions.project_key`, making provider-local attribution act like a public project boundary. | Provider keys remain provenance aliases only; profile activity owns canonical session discovery and zero/one/many repository attribution. | +| `session:019f2524-534d-7bd1-a3b1-675f242dcc0e` | Claude’s first CWD could misattribute later cross-worktree messages. | Location is an interval-valued observation per Turn/message; no session-wide first-CWD overwrite. | +| `session:019f1204-5575-72a1-a2d1-ab5c6d1b310d` | “No project index found” guidance suppressed otherwise available session and memory capabilities. | Capability availability is domain-specific; absent code graph does not disable profile activity, messages, memory, Git, or registry discovery. | +| PR #425 / unresolved historical session anchor: branch `codex/explicit-store-consolidation`, final head `d3bb28b57bef6f7fa513ff4b0645ce5e31a97872`, merge `de3d05dc` | At the planning snapshot, explicit root/worktree/branch lookup stopped before semantic Git/session analysis because the same checkout had healthy selected and legacy stores. The selected lane reported zero automation files while the legacy lane reported 3,470; path/current-project selection could not decide authority. | Resolution returns both candidates and typed coverage. The now-merged consolidation freezes/backs up both, identifies holders by file identity, preserves aliases/remapped LCM edges, reconciles every table/collision, verifies exhaustively, and publishes marker/registry atomically before the exact recipe is retried; no CWD/path/newest-mtime/empty-lane inference. | + +Current supported-surface reproduction also exposed a composability break: `tracedecay_message_search(project_scope="all_registered")` can return a session from another registered project, but `tracedecay_lcm_load_session` is active-project-only and rejects project selectors. Search-to-exact-retrieval must therefore be a required end-to-end conformance test, not two independently green tools. + +The Rspack/Rsbuild/React Router family is the primary cross-repository benchmark because real work regularly needs all of these evidence sources: + +- `rsbuild-plugin-react-router`: product code, tests, branch, PR, benchmark, and agent worktree. +- `rsbuild`: plugin API, dev-server, environment, `loadBundle`, middleware, and memory-filesystem contracts. +- `rspack`: compiler, output filesystem, asset emission, runtime, resolver, and bundler behavior. +- `react-router`: framework semantics and upstream version behavior. +- synthetic benchmark repositories: downstream performance and integration evidence. +- support or fork repositories: reproducible failures, stacked branches, and published canaries. + +## 3. Canonical scope vocabulary + +Do not expose storage topology as product scope. Use these identities: + +| Identity | Meaning | Cardinality/notes | +|---|---|---| +| `ProfileId` | Local privacy and ownership boundary. | One profile can contain many repositories and stores. | +| `RepositoryId` | Durable source-control lineage, independent of checkout path. | Derived from evidence-scored remote/common-history identity; ambiguity is preserved. | +| `ProjectId` | Registered TraceDecay product unit and policy/config boundary. | Usually maps to one repository, but may represent a non-Git workspace or explicit subproject. | +| `CheckoutId` | One filesystem checkout of a repository. | Main checkout and worktrees are peers. | +| `WorktreeId` | Git worktree identity, including git common dir and admin record. | Path is a versioned alias, not identity. | +| `RefId` | Branch/tag/remote-ref lineage. | Ref name is mutable; observations are time-qualified. | +| `CodeSnapshotId` | Immutable code/Git state used for a graph query. | Normally commit/tree plus index/config/parser generation; distinct from `GraphGenerationId`. | +| `ProjectSetId` | Saved or ephemeral set of repositories/projects. | Supports related systems and benchmarks. | +| `CollectionId` | User-saved heterogeneous entity/query collection. | May cross projects. | +| `SessionId`, `AgentId`, `WorkflowId` | Activity identities in the profile activity domain. | Attribution to repositories/worktrees is zero, one, many, or unknown over time. | +| `InitiativeId`, `PlanId`, `WorkItemId`, `ExecutionAttemptId`, `ExecutorRegistrationId` | Canonical plan-24 work/execution identities in the profile activity domain. | Scope may span zero/one/many repositories; an attempt pins one exact writable binding plus authorized reads. Boards and executor queues do not mint scope identity. | + +`project_key`, transcript CWD, path hash, graph database filename, store directory, branch database, and provider-local project fields are aliases/provenance. They never become the primary public selector. + +## 4. `ScopeSelectorV2` + +Every transport generates or consumes the exact `ScopeSelectorV2`, `ScopeRootV2`, and `ScopeTargetV2` definitions owned by plan 01 §14. This plan adds resolution, federation, and UX requirements but defines no second selector type; compile-time schema-digest tests fail if any transport or SDK copy diverges. + +The human-readable JSON below shows a two-repository plus worktree-locator request with the exact field set; the contract generator freezes the final discriminated-union spelling. `include`, `ScopeExpr`, root-local snapshot fields, and transport-specific `project_key` do not exist: + +```json +{ + "version": 2, + "roots": [ + { "kind": "repository", "target": { "kind": "canonical", "ref": "repo_7c12e9a14fe44f77a0f9c29b3760a812" } }, + { "kind": "repository", "target": { "kind": "canonical", "ref": "repo_2b198ef27e36492e92bd15df8a85241d" } }, + { + "kind": "worktree", + "target": { "kind": "locator", "locator": { "kind": "worktree_path", "value": "/worktrees/feature", "repository_hint": null } } + } + ], + "exclude": [], + "time": { "as_of": "2026-07-09T20:00:00Z" }, + "activity_attribution": "overlap", + "coverage": "allow_partial", + "freshness": { "max_age_seconds": 300, "on_stale": "report" }, + "traversal": { "kind": "related", "max_depth": 1 }, + "ambiguity": "return_candidates", + "limits": { "max_projects": 20, "max_shards": 40, "max_graph_nodes": 10000 } +} +``` + +Supported selector kinds: + +- `CurrentInvocation` and `AllAuthorized { profile_id }`. +- `Profile`, `ProjectSet`, `Collection`, `Repository`, `Project`, `Checkout`, and `Worktree`. +- `Ref` (including branch/tag locators), `Commit`, `CodeSnapshot`, `GraphGeneration`, and `PullRequest`. +- `Session`, `Thread`, `Turn`, `Agent`, `Goal`, `Workflow`, `AutomationRun`, `Initiative`, `Plan`, `WorkItem`, `ExecutionAttempt`, and `Executor`. +- `SavedView` and typed `GraphNeighborhood`. + +Resolution modes: + +- `ScopeTargetV2::Canonical` is an exact stable ID. +- `ScopeTargetV2::Locator` runs token-aware path/name/alias/remote/branch/PR resolution; `ambiguity` controls error versus candidates. +- `traversal` may propose or explicitly include bounded graph-related scopes; it never silently adds them. +- `AllAuthorized { profile_id }` is the only All root. + +## 5. Resolution algorithm + +The resolver is a shared application service, not duplicated transport code: + +1. Parse typed IDs, URLs, filesystem paths, Git remotes, PR/branch/commit syntax, and natural-language tokens. +2. Normalize paths without erasing symlink, casing, mount, or historical-alias evidence. +3. Resolve exact stable IDs first. +4. After authorization selects the privacy domain/key epoch, query the catalog's versioned privacy-domain-keyed exact alias-routing digests; verify every selected candidate against canonical alias evidence in its owner shard. +5. Run token-aware matching over keyed token/quoted-phrase routing digests with per-token `AND` across an `OR` field set; no literal path/remote/alias enters the catalog. +6. Add typo/fuzzy candidates from bounded keyed n-gram routes only below the exact/token confidence threshold, then verify in authorized owner shards. +7. Add relationship evidence: shared Git common dir, remote, commit ancestry, registered project family, previous co-query/co-investigation, dependency, generated artifact, PR/base/head, and explicit user project set. +8. Score candidates with field/evidence explanations; never promote recency over an exact ID/path. +9. If one candidate exceeds the calibrated exact threshold, resolve it. +10. Otherwise return bounded candidates with stable IDs, discriminators, and a ready-to-resubmit selector. + +Disambiguators include owner/repository, canonical path, worktree path, branch/ref, head commit, last indexed time, store health, default branch, and reason matched. Credential-bearing remotes are redacted before rendering. + +### 5.1 Explicit-target rule + +If the prompt/command names a repository, project, path, worktree, branch, PR, session, or agent: + +- The transport extracts it as a candidate selector. +- The application service resolves or rejects it before query execution. +- It never executes against `current` merely because resolution failed. +- A failure response includes candidates and one exact retry request/command. + +### 5.2 Current-default rule + +If no target is present, `current` may resolve from the invocation CWD/host context. Every response still reports: + +```text +scope: current -> project:proj_rsbuild_plugin_react_router +worktree: /.../dev-rebuild-optimizations (branch codex/dev-rebuild, head abc1234) +``` + +## 6. Registry and store architecture + +`catalog.db` owns store manifests, stable entity-to-owner routes, and versioned privacy-domain-keyed exact/token/ngram alias-routing digests. Canonical alias values/history remain in authorized `activity.db` or project owners. `activity.db` owns canonical provider activity. Project shards own repository/project-scoped code, delivery, knowledge, and policy projections. + +Alias-routing digests are versioned records, not bare hashes: every digest row carries the privacy-domain key epoch/ID, tokenizer/normalizer version, digest algorithm version, and catalog generation, so key rotation or tokenizer change re-derives routes instead of silently corrupting resolution. Plan 02 owns the storage schema for these route tables. + +Required behavior: + +- A registry watcher reconciles Git worktree admin data, filesystem presence, remotes, canonical alias evidence, keyed catalog routes, tombstones, and store manifests without eagerly opening every shard. Resolution prunes through the routing index and opens only authorized candidate owners for literal/evidence verification. +- Discovery is idempotent and provenance-bearing. A transient worktree path does not create a new repository identity. +- Stale/deleted checkout rows are historical aliases with state, not active results and not silent garbage. +- Duplicate stores for one canonical repository enter conflict/quarantine workflow; reads expose the conflict rather than picking newest mtime. +- Renames and moved paths preserve adoption receipts and prior stable IDs. +- A non-Git project remains addressable without fabricated repository identity. +- Domain availability is per store/capability. A missing graph can coexist with healthy sessions, facts, Git observations, or automation data. +- Registry garbage collection has preview, evidence, retention, apply receipt, and rollback; it does not delete stores merely because a path is absent. + +## 7. Cross-project session and activity model + +Provider activity is ingested once into the profile activity journal. Repository/worktree/project attribution is a temporal evidence relation: + +- Session starts in repository A, later Turns run in worktree B. +- Parent agent is in A while a subagent is spawned for B. +- A tool call queries code in C without changing the host CWD. +- A user discusses D while no local checkout is active. +- One workflow coordinates A, B, and C. + +The projection stores each observation’s location evidence independently: provider CWD, tool `workdir`, resolved checkout/worktree, Git common dir, branch/head, explicit tool selector, referenced entity, and confidence. It never overwrites the whole session with the first or last CWD. + +Activity filters support: + +- `produced_in`: the actor wrote/changed an artifact in the scope. +- `executed_in`: the Turn/tool ran in the scope. +- `queried`: the actor intentionally queried the scope. +- `discussed`: the message referenced the scope. +- `observed`: the session encountered evidence from the scope. +- `overlap`: any evidence interval overlaps the requested scope. +- `primary`: highest-confidence task scope, with reason and abstention. + +Search hits return the activity entity from `activity.db` plus relations to project entities. They do not require guessing which project shard contains a second copy of the transcript. + +## 8. Federated code and Git graph + +Code graph federation is query planning over immutable snapshot generations, not a physical mega-database join by default. + +### 8.1 Snapshot selection + +For each selected repository/worktree: + +1. Resolve requested as-of/ref/commit/working-tree state. +2. Select one compatible code-graph generation and report parser/index generation. +3. For dirty worktrees, represent index and working-copy overlays separately from committed base. +4. Refuse to imply live working-copy coverage when only the base commit is indexed. +5. Report staleness and commits/dirty changes since snapshot. + +### 8.2 Cross-repository edges + +Typed cross-repository edges include: + +- package dependency and lockfile resolution. +- plugin/host API use. +- generated or published artifact provenance. +- fixture/vendor/submodule/fork lineage. +- Git cherry-pick/backport/patch equivalence. +- PR head/base and downstream test/benchmark relation. +- symbol/type/API reference when supported by language/package resolution. +- session/tool/agent observation and produced/impacted evidence. +- manually curated “related system” project sets. + +Every edge has source evidence, captured time, valid interval, confidence, algorithm/version, and snapshot endpoints. The query planner may expand through these edges only when the user asks for related/cross-project context or a bounded policy selects it; it never silently rewrites a one-project query into All. + +### 8.3 Federated ranking + +Normalize per-shard scores only after preserving channel/raw scores. Global merge applies: + +- exact ID/symbol/literal priority. +- scope intent and explicit-target boosts. +- repository diversity when the query asks for multiple projects. +- per-repository caps to prevent a large repo dominating. +- snapshot/freshness penalties with explanation. +- duplicate/fork/generated-source clustering. +- optional dependency/graph reranking. + +## 9. Search-to-retrieval contract + +Every search result card includes: + +- canonical `entity_ref` and domain `RetrievalAnchorId` resolving to `RetrievalAnchorRecordV1`. +- source profile/repository/project/worktree/ref/snapshot. +- event and ingest time. +- provider/origin/audience/kind. +- one-line rank reason and channel scores. +- exact projection/source watermarks. +- representative/duplicate cluster information. +- permitted expansions and related entities. + +The following sequence must work across any authorized shard: + +```text +search -> result RetrievalAnchorId -> authorized RetrievalAnchorRecordV1 -> exact entity/Turn/message/session load + -> adjacent context -> source observation/payload -> export manifest +``` + +It must not require changing CWD, restarting MCP in another worktree, discovering a private store, or replaying the original search. A retrieval reference is location-independent and remains valid across project rename/worktree deletion; retention/redaction may later return an explicit tombstone. + +Distributed cursors bind query digest, scope-set generation, per-shard cursor/watermark, ordering, policy/ranker version, and expiration. Resume never silently searches a different project set after registry change. + +## 10.

Official API and SDK relationship + +The official API plan in [`17-official-public-api-and-sdks.md`](17-official-public-api-and-sdks.md) owns transport, authentication, versioning, schemas, and SDK generation.

Use test-first, reviewable PR slices; this document adds no separate business-logic layer. + +**Goal:** Make TraceDecay's full supported capability surface directly queryable by agents and integrations through one stable, documented, contract-first API with first-party Rust, TypeScript, and Python SDKs, while preserving semantic parity with CLI, MCP, HTTP, dashboard, exports, and live streams. + +**Architecture:** `tracedecay-application` remains the sole use-case boundary and `tracedecay-tool-catalog` remains the capability registry. `tracedecay-api` publishes the official HTTP/SSE/OpenAPI contract; generated schema packages and small hand-written runtimes expose it as idiomatic SDKs. CLI and MCP use the same application/catalog definitions but do not loop through HTTP. Every binding is verified against the same semantic fixtures, typed scopes, stable anchors, errors, coverage, and replay rules. + +**Initial deployment:** Local-first. A user-owned Unix-domain socket or authenticated loopback HTTP endpoint is supported. Remote or hosted service operation is not assumed by this plan and must not weaken the local trust, privacy, or authorization contract. + +**Publication snapshot:** [master §2.6](../2026-07-09-tracedecay-brain-rewrite.md#26-current-master-accepted-changes) plus [plan 13](13-research-provenance-and-context-anchors.md) are normative. Historical 0.0.47/0.0.48 fixture counts remain version-labelled evidence, not the current surface. The official surface includes ordinary-profile Hermes, current message views, doctor authority, race-safe `move_symbol`, typed identity split and merged consolidation (`de3d05dc`), release-integrity gates, proxy/reconnect/no-write-replay, negotiated catalog refresh, fact rank/counters, exact analytics, untracked/divergent data recovery, lifecycle-safe maintenance, restart-safe applied-manifest retirement, and operator-only consolidation/recovery. + +--- + +## 1. Relationship to the Other V2 Plans + +This plan complements, rather than replaces, the following ownership: + +- `01-domain-crate.md` owns canonical IDs, entities, events, scopes, evidence, provenance, privacy labels, versions, and stable error primitives. +- `01-domain-crate.md` owns the bounded `TraceQueryV1` AST/value/schema contract; `05-query-crate.md` owns parsing, validation, canonicalization, planning, ranking evidence, frozen snapshots, distributed cursors, partial coverage, export rows, and live deltas. +- `06-policy-crate.md` owns capability routing and deterministic hint/policy evaluation. +- `08-tool-catalog-crate.md` owns use-case identity, input/output schema references, binding metadata, availability, effects, version state, and discovery copy. +- `09-application-crate.md` owns authorization, use-case orchestration, command semantics, jobs, idempotency, and audit receipts. +- `10-api-crate.md` owns Axum HTTP/SSE framing, loopback security, the checked OpenAPI artifact, and dashboard TypeScript client. +- `13-research-provenance-and-context-anchors.md` owns the cross-plan research manifest and durable evidence recipes. +- `15-search-quality-evaluation-and-retrieval-research.md` owns relevance judgments and retrieval evaluation. +- `16-cross-project-repository-worktree-scope.md` owns the resolver/routing UX and cross-repository regression corpus while consuming the exact domain selector. +- `18-secret-detection-redaction-and-private-data-safety.md` owns the sanitizer, taint-state wrappers, privacy status semantics, and forbidden-sink conformance. Public contracts only expose eligible content or explicit redacted/denied/unknown states. +- `20-configuration-control-plane.md` owns configuration descriptors, resolution, provenance, history, impact, credentials, and autonomous-curation policy; generated SDK/API surfaces expose those exact use cases without inventing client defaults. +- `21-cli-mcp-tool-surface-and-output-unification.md` owns the generated binding and presentation parity contract; public SDK JSON shares its sealed views, typed outcomes, pages, retrieval anchors, notices, freshness, and provenance without scraping human Markdown or CLI envelopes. +- `22-incremental-context-scout-and-suggestion-envelopes.md` owns scout status/replay/feedback/system-control and suggestion-envelope semantics; SDKs cannot trigger delivery or bypass read-only lab guards. +- `23-session-lcm-temporal-retrieval-and-evaluation.md` owns temporal search/context/lineage/replay/evaluation semantics; SDK modes, anchors, cursors, coverage, no-answer reasons, and hydration are generated from that same contract. +- `24-canonical-task-plan-graph-and-multi-agent-executor.md` owns initiative/plan/work-item/executor/scheduler/context-packet semantics and the many-host adapter protocol; this plan generates supported orchestration/monitoring clients without turning an SDK into a task query engine, scheduler, route selector, event journal, lease authority, or board database. Task reads use registered entity/attribute/traversal/projection values inside canonical `TraceQueryV1`; `WorkClaimV1` is advisory and `task_offers.accept` is the sole public command that invokes atomic execution admission. The read/command surface is the inventory in plan 09 §§9–10 and plan 10 §8: reads are GET/query POST, every mutation is a POST command envelope, and task deltas use the ordinary subscription protocol rather than `/task-events`. +- This plan owns the declaration that the HTTP contract is an **official public integration surface**, agent-oriented discovery and documentation, first-party Rust/TypeScript/Python packages, direct-client lifecycle, compatibility policy, and public conformance program. + +There is no independent "SDK API" business layer. SDKs serialize generated request types, call the official transport, deserialize generated response types, and provide bounded ergonomics such as pagination and reconnect helpers. They may not recreate ranking, scope resolution, command authorization, replay classification, or retry policy by guesswork. + +## 2. User and Agent Outcomes + +An agent should be able to: + +1. Discover the endpoint and current protocol without scraping logs or dashboard HTML. +2. Mint or receive a least-privilege, time-bounded credential through an explicit user-approved path. +3. Ask what TraceDecay can do and receive catalog-backed methods, schemas, cost/freshness classes, examples, required scopes, and current availability. +4. Resolve "rspack", a repository path, a worktree path, a branch, PR, session, agent, or `All` into canonical typed scope IDs without silently querying the active project. +5. Query code, Git, sessions, messages, agents, workflows, goals, memory, skills, automation, analytics, hints, costs, and health through one consistent envelope. +6. Traverse the Graph-of-Graphs from any stable entity to related entities while seeing evidence, confidence, time validity, source watermarks, and missing coverage. +7. Enumerate large stores and cross-project results using opaque resumable cursors rather than result caps or ephemeral response handles. +8. Subscribe to authorized changes, reconnect deterministically, detect gaps, and resynchronize. +9. Replay a historical or synthetic hint/search decision in a no-write lab and compare historical versus current policy without altering live analytics, facts, counters, claims, or outcomes. +10. Inspect an operation-specific preflight when required and, only with explicit mutation authority, execute its named command with idempotency, optimistic version checks, audit, and a durable operation receipt. +11. Recover from every typed error using a machine-readable retry/restart/current-binding directive rather than prose parsing. +12. Cite stable TraceDecay retrieval anchors in its own plan, report, PR, or handoff so a later agent can recover the exact evidence. +13. Query or operate one cross-repository initiative, call transactional `work_items.assign_set` to assign bounded work sets to Codex and Claude routes with explicit provider/model/reasoning-effort/tool/budget constraints, inspect attempt list/detail/timeline and start-versus-current accepted packet state, list/accept/decline addressed offers, administer offers through an authorized revoke command, manage direct task notifications, and subscribe to canonical task read-model deltas without MCP, dashboard mediation, or a separate task-event stream. + +Human developers should be able to accomplish the same work with `curl`, generated documentation, or an SDK without learning MCP wire details or reverse-engineering the dashboard. + +## 3. Non-Goals and Explicit Boundaries + +- No public SQL, FTS syntax, raw SQLite connection, arbitrary graph-store query language, filesystem traversal, shell execution, or renderer/plugin code upload. +- No hidden chain-of-thought endpoint. Only provider-exposed, retained, access-authorized reasoning summaries/artifacts and explicit coverage markers may be returned. +- No unbounded "dump everything" JSON response. Enumeration, graph expansion, search, timeline, export, and event delivery are all bounded and cursor/stream based. +- No automatic remote bind, cloud account, multi-tenant identity server, or internet exposure in the initial V2 release. +- No SDK-specific behavior. Rust, TypeScript, Python, raw HTTP, CLI JSON, MCP JSON, dashboard, export, and SSE snapshot must agree before presentation differences. +- No stale-client behavior emulation. Data migration and rollback may preserve user data; they do not keep obsolete live names, schemas, or semantics executing. +- No general GraphQL surface in V2. The bounded typed query/graph operations are easier to cost, authorize, version, and replay. +- No task-specific query language. Generated task helpers build/import the one `TraceQueryV1`, return its canonical digest, and round-trip through generic query, saved views, subscriptions, CLI/MCP, and dashboard without semantic conversion. +- No WebSocket requirement. Request/response, SSE, bounded NDJSON, and asynchronous operation polling cover the initial official surface. +- No agent credential minted merely because a local process can connect. Endpoint reachability is not authorization. +- No "helpful" SDK fallback from an explicit cross-project scope to the current project. + +## 4.

Pipeline: domain schemas + application use-case registry + plan 08 capability catalog → canonical contract IR snapshot (`crates/tracedecay-api/contract/tracedecay-contract-ir.v1.json`, owned by plan 17) → generated OpenAPI 3.1 (`crates/tracedecay-api/src/openapi/generated.json`, hosted by plan 10), the review rendering `crates/tracedecay-api/openapi/tracedecay-v2.yaml`, and the public JSON Schemas (`crates/tracedecay-api/schemas/*.schema.json`) → plan 10's Axum adapters conform to the IR-generated document, with utoipa reflection retained as validation only (CI regenerates the utoipa-derived document and fails unless it is semantically identical to the IR-generated artifact) → the generated TypeScript schema core at `packages/tracedecay-client/src/generated/` is produced from the IR-generated OpenAPI and hosted per plan 10, while plan 17 owns SDK packaging and conformance. The capability catalog remains the registry of record for capability/binding identity; the contract IR is its frozen public projection, and no plan or adapter maintains a second route registry. + +The canonical contract IR snapshot is a named, checked artifact, not an in-memory build step: + +- Path: `crates/tracedecay-api/contract/tracedecay-contract-ir.v1.json`. +- Format: canonical JSON (UTF-8, sorted object keys, LF line endings, no floats) with one top-level `ContractIrV1` object carrying `ir_version` (integer, bumped only for IR-format changes), `protocol_version`, `source_digests` (domain schema digest, application use-case registry digest, capability catalog digest, generator versions), and `use_cases` sorted by `use_case_id`. +- Each `use_cases[]` entry carries exactly the fields listed below; unknown fields fail generation. +- Uniqueness: `use_case_id` is the primary key; a duplicate ID or duplicate HTTP binding fails the build. +- Lifecycle: regenerated deterministically from the registry snapshot; CI generates twice and diffs; hand edits are rejected by the generated-file marker; IR diffs are reviewed like code and drive the compatibility manifest. + +The contract intermediate representation contains, for every public use case: + +- stable `UseCaseId`, semantic version, lifecycle state, owning domain, and summary; +- exact request, response, event, error, and retry schema references; +- allowed typed scope kinds and whether multiple roots/exclusions are legal; +- read, preview, mutate, destructive, or administrative effect class; +- required authorization grants, privacy domain, sensitivity, and audit behavior; +- idempotency, optimistic version, operation/job, and compensation semantics; +- pagination, streaming, export, and maximum inline result behavior; +- consistency/freshness requirements and expected partial-result behavior; +- cost/latency class, default/max budgets, rate-limit bucket, and availability prerequisites; +- bindings to HTTP operation, SDK method, CLI command, MCP tool, dashboard action, hook route, and export profile; +- stable examples containing synthetic data only; +- replacement/current-binding details when a contract is removed. + +Compile/generation fails on duplicate IDs, undocumented routes, missing authorization, missing stable error codes, unbounded collections, transport-only fields leaking into domain schemas, or a binding without semantic fixtures. + +### 5.2 OpenAPI and JSON Schema rules + +- Publish OpenAPI 3.1 and JSON Schema 2020-12. +- Every union uses an explicit discriminator; SDKs never infer a variant from missing fields. +- IDs use named string formats such as `tracedecay-entity-id`, not plain undocumented strings. +- Timestamps use RFC 3339 UTC and retain source precision/uncertainty metadata where relevant. +- Durations use integer microseconds or named ISO-8601 fields consistently, never ambiguous numbers. +- Integer counts use 64-bit-safe representations; TypeScript generation must not silently narrow values above `Number.MAX_SAFE_INTEGER`. +- Optional and nullable are distinct. Unknown, unavailable, redacted, not-applicable, and zero are distinct states. +- `additionalProperties` is disabled for closed request objects. Forward-compatible event/provider payloads live only in explicit `extensions`/opaque fields with size/privacy limits. +- Examples and descriptions are generated from synthetic fixtures and secret-scanned. +- Every operation declares all normal, partial, auth, scope, version, limit, conflict, and internal problem responses. + +## 6. Version and Compatibility Contract + +### 6.1 Version identities + +The public contract exposes separate identities: + +- **API major:** path namespace, initially `/api/v2`. +- **Protocol version:** exact wire/semantic compatibility version, returned by discovery and every response. +- **Catalog digest/version:** available use cases and binding definitions. +- **Schema digest:** canonical request/response/event definitions. +- **Data/projection versions:** returned in snapshot/freshness/coverage metadata, not confused with protocol compatibility. +- **Policy/ranking/model versions:** attached to explain/replay results, not used as API version substitutes. + +Clients send their supported protocol range and generated schema digest through standard client headers. The server returns its selected protocol and digests in response metadata/headers. If the client's supported range does not intersect the server's, the server performs no semantic work and rejects with HTTP 426 and a stale-client registry code — `client_update_required` when the client is older, `daemon_restart_required` when a newer daemon/binary is installed but not yet serving — carrying minimum/current protocol, current binding, and the exact update/restart command; it never guesses a protocol. + +### 6.2 Change policy + +- Additive optional response fields and new enum variants require generated clients to retain/represent unknown values safely; they do not permit changing existing meaning. +- Request-side evolution is equally explicit: request objects stay closed (`additionalProperties: false`), servers reject unknown named fields, and forward-compatible request additions travel only in each request's declared bounded `extensions` slot, which servers accept and ignore when unrecognized. A client may send a new named request field only once the server's advertised protocol version includes it; anything else requires a protocol version bump. This one rule replaces any per-schema discretion in transport plans (plan 10 §7.3 cites it). +- New required request fields, removed fields, changed defaults, changed ordering, changed error semantics, or changed effect behavior require a new protocol version and usually a new API major. +- Capability lifecycle is explicit: `experimental`, `current`, `scheduled_for_removal`, `removed`. Experimental use requires an opt-in header/grant and never silently becomes stable. +- Deprecation within a current protocol may warn and provide the exact current binding, but the deprecated binding has a declared short removal release and cannot change behavior to imitate a replacement. The warning channel is typed: a `capability_deprecated` `ApplicationWarning` in `meta.warnings` carrying the current binding and the removal release/date, plus a standard HTTP `Sunset` header; SDKs surface both rather than parsing prose. +- At cutoff, obsolete clients/routes/tools receive a typed stale-client response from this plan's contract-IR error registry — `client_update_required`, `daemon_restart_required`, or `capability_replaced { current_binding }` — with HTTP 426 where appropriate and exact restart/update/current-route/current-SDK guidance. They are not proxied to legacy handlers or translated with guessed defaults. +- Rollback restores a prior **compatible V2 server and data snapshot** under an explicit operator receipt. It never revives obsolete live V1 names as fallback behavior. +- Support windows are published as dates/releases in a machine-readable compatibility manifest. Clients must not infer support from a successful TCP connection. + +## 7. Endpoint and Client Discovery + +### 7.1 Local endpoint lifecycle + +Add an explicit operator surface: + +```text +tracedecay api serve +tracedecay api status --json +tracedecay api token create --read-only --ttl 1h --scope +tracedecay api token list +tracedecay api token revoke +tracedecay api openapi --output +tracedecay api docs +``` + +`api status --json` returns only safe discovery material: endpoint kind, socket path or loopback origin, server/protocol version, health, catalog/schema digest, authentication method, docs/OpenAPI path, and current profile ID. It never returns bearer/session/CSRF secrets. `api token create|revoke` bind audited application commands; `api token list` binds the elevated read use case `auth.tokens.list` and returns metadata only. The per-launch bootstrap bearer may execute only `auth.tokens.create` for the initial admin-class token (plan 10 §10.2). + +Discovery precedence for SDKs is explicit: + +1. caller-supplied endpoint and credential; +2. `TRACEDECAY_API_ENDPOINT` and a supported credential provider, never a token embedded in the endpoint URL; +3. user-owned runtime discovery file with mode `0600`, process identity, expiry, endpoint, and public digests; +4. deterministic default Unix socket or loopback status probe; +5. typed `endpoint_not_found` with the exact command to start/check the service. + +SDKs never scan processes, ports, parent directories, dashboards, MCP config, or transcript files to guess an endpoint. + +### 7.2 Bootstrap endpoints + +- `GET /api/v2/meta` returns protocol, server version, instance/profile identity, catalog/schema digests, time, health summary, limits profile, and current compatibility policy. It is authenticated — plan 10's rule that every route except static assets and the one-time bootstrap exchange requires authentication holds without exception; endpoint-without-credential discovery uses `tracedecay api status --json` or the `0600` runtime discovery file (Section 7.1), never an anonymous HTTP handshake. +- `GET /api/v2/openapi.json` returns the exact checked contract for the selected current protocol. +- `GET /api/v2/schemas/{digest}/{name}` returns an allowlisted public schema artifact. +- `GET /api/v2/capabilities` provides cursor-based capability discovery, not one unbounded registry blob. +- `GET /api/v2/bindings/{use_case_id}` provides current CLI/MCP/HTTP/SDK/dashboard bindings and prerequisites. +- `POST /api/v2/scopes:resolve` resolves one or many human locators into canonical scopes with ambiguity and coverage. + +## 8. Capability Parity and Agent-Friendly Discovery + +Every current V2 application use case must have exactly one catalog disposition: + +- public and bound; +- public but unavailable with typed prerequisite/remediation; +- internal implementation detail; +- destructive/administrative and explicit-grant only; +- migration-only; +- removed with a current replacement; +- intentionally unsupported with rationale and review owner. + +There is no accidental API surface from Axum routes and no undocumented CLI/MCP-only capability. A public capability may omit a particular transport only when the catalog declares why; for example, a browser-only bootstrap handshake or a local host hook callback. + +Capability discovery returns: + +```json +{ + "use_case_id": "usecase.query.search-universal", + "version": "2.0.0", + "summary": "Search authorized TraceDecay evidence across selected scopes", + "effects": "read", + "scopes": ["all", "collection", "repository", "project", "worktree", "session", "agent"], + "availability": {"state": "available", "requirements": []}, + "cost_class": "interactive", + "freshness": "frozen_or_eventual", + "pagination": "opaque_cursor", + "bindings": { + "http": "POST /api/v2/search", + "rust": "Client::search", + "typescript": "client.search", + "python": "client.search", + "cli": "tracedecay search", + "mcp": "tracedecay_search" + } +} +``` + +Agent-oriented descriptions are concise routing metadata, not a second prompt-only catalog.

They are exhaustive for these families; an SDK cannot collapse them into `get_work_item`, invent a client-side packet pointer update, or implement an offer/notification workflow locally.

Typed ScopeSelectorV2 + +Scope must be identical across API, SDKs, CLI, MCP, dashboard, saved views, exports, and retrieval anchors. `project_key` and a process's active checkout are internal/provider locators, not the public identity model. + +### 9.1 Selector model + +Plan 01 §14 solely defines `ScopeSelectorV2`, `ScopeRootV2`, `ScopeTargetV2`, and `ScopeLocatorV2`; plan 16 owns their federation and resolution behavior. The official contract IR imports their generated schema digest unchanged rather than restating a client variant. The task roots `Initiative`/`Plan`/`WorkItem`/`ExecutionAttempt`/`Executor` target plan 24's canonical task graph through the plan 09 §§9–10 / plan 10 §8 inventories. Resolution returns the canonical selector and candidates before query planning. + +### 9.2 Resolution rules + +- Canonical ID is exact and preferred. +- A named external repository/worktree/project never falls back to the active project. +- One exact candidate resolves automatically and records the evidence/alias used. +- Multiple candidates return `scope_ambiguous`, safe disambiguating labels, candidate canonical IDs, and a ready-to-retry request object. +- No candidate returns `scope_not_found`, searched registries/stores, safe near matches, registration/index status, and legal next actions. +- Same-basename repositories are disambiguated with safe parent/common-dir/registry identity, never credential-bearing remote URLs. +- Repository, checkout, worktree, branch/ref, and code snapshot remain different identities. A worktree query cannot silently read the base checkout graph. +- `AllAuthorized { profile_id }` means all authorized, registered selected-profile evidence. `CurrentInvocation` is legal only when the binding catalog declares it; `ScopeResolutionV2.defaulted_current` makes that choice visible. Skipped/locked/stale/unavailable stores appear in coverage. +- A session or agent may relate to zero, one, or many repositories/worktrees. The API does not force one provider project key into canonical ownership. +- Scope resolution is versioned and produces a `ScopeResolutionId` usable in the query/retrieval anchor. The server revalidates authorization and liveness; it does not trust a client-cached path mapping forever. + +### 9.3 Binding ergonomics + +- HTTP accepts the full tagged selector. +- SDKs expose builders and typed constructors, never stringly `scope="all"` conventions. +- MCP uses the same schema under one `scope` property; convenience `project_id`/`project_path` fields are generated aliases only while current and cannot conflict. +- CLI exposes consistent `--all`, `--collection`, `--repo`, `--project`, `--worktree`, `--ref`, `--session`, and `--agent` flags generated from the selector registry. +- Every response echoes the resolved canonical scope, safe labels, snapshot watermarks, and coverage. Defaults such as "active project" are explicit in metadata. + +## 10. Stable IDs, Retrieval Anchors, and Deep Links + +All durable public IDs are opaque typed values with stable prefixes/check digits or equivalent validation. They never encode a raw path, prompt text, secret, database row number without namespace, or mutable display name. + +The public identity families include profile, repository, project, checkout, worktree, code snapshot, ref, commit, PR, session, thread, message, Turn, agent, workflow, goal, event, entity, relation, fact/version, skill/version, automation run/artifact, policy bundle, query/replay run, export, operation, and research anchor. + +Domain `RetrievalAnchorRecordV1`, keyed by opaque `RetrievalAnchorId`, contains the following contract; public results/deep links expose the ID, and the API/SDK must not create a transport-specific anchor record: + +- canonical target ID and entity kind; +- resolved scope ID and access/privacy-domain digest; +- source/store identity class without a sensitive backing path; +- immutable source/event/message/commit identifiers when available; +- snapshot/vector watermarks and data/projection/schema versions; +- view/representative mode and expansion recipe; +- minimal typed retrieval use case plus canonical request digest; +- evidence/provenance links and redaction/retention state; +- creation time and a declared durability class. + +| Capability | Official HTTP binding | Rust | TypeScript | Python | +|---|---|---|---|---| +| `retrieval_anchors.metadata_batch_get` | `POST /api/v2/retrieval-anchors:metadata-batch` | `get_retrieval_anchor_metadata_batch` | `getRetrievalAnchorMetadataBatch` | `get_retrieval_anchor_metadata_batch` | +| `retrieval_anchors.resolve` | `POST /api/v2/retrieval-anchors:resolve` | `resolve_retrieval_anchors` | `resolveRetrievalAnchors` | `resolve_retrieval_anchors` | +| `retrieval_recipes.execute` | `POST /api/v2/retrieval-recipes:execute` | `execute_retrieval_recipe` | `executeRetrievalRecipe` | `execute_retrieval_recipe` | + +Rules: + +- Ephemeral response handles, page cursors, bearer tokens, event subscription IDs, and browser state are never the only retrieval citation. +- `retrieval_anchors.metadata_batch_get` is bound only to `POST /api/v2/retrieval-anchors:metadata-batch` and returns bounded safe identity/state/tombstone metadata without content. +- `retrieval_anchors.resolve` is bound only to `POST /api/v2/retrieval-anchors:resolve` and performs authorized exact record/payload resolution at a frozen watermark. +- `retrieval_recipes.execute` is bound only to `POST /api/v2/retrieval-recipes:execute` and performs bounded versioned recipe execution with scope/version/watermark drift and coverage. +- Resolution returns exact, moved/adopted identity, retained-but-redacted, expired-by-retention, unavailable-store, or denied. It never silently points to a similar row. +- Deep links contain an anchor ID or saved-view ID, not sensitive query text. Authorization is always rechecked. +- SDK result types surface `anchor` directly and provide only the generated methods in the table above; convenience `.data` access must not hide it or conflate metadata with payload authority. +- Export manifests include anchors and hashes so a later agent can verify the source snapshot. + +## 11. Request, Response, Coverage, and Consistency Envelopes + +### 11.1 Requests + +Every request carries or inherits: + +- resolved typed scope; +- caller-selected consistency: `eventual`, `frozen`, `at_least_watermark`, or allowed domain-specific mode; +- bounded deadline and resource budget; +- requested fields/payload policy; +- result/page bound; +- optional trace/correlation ID; +- explicit replay/as-of mode when applicable. + +The server owns actual authorization, plan cost, selected shards, and captured watermarks. Client-supplied estimates are hints only. + +### 11.2 Responses + +Every success uses one canonical envelope: + +```rust +pub struct ApiResponse { + pub data: T, + pub meta: ApiMeta, +} + +pub struct ApiMeta { + pub request_id: RequestId, + pub use_case: UseCaseRef, + pub protocol: ProtocolRef, + pub catalog_snapshot: CatalogSnapshotRefV1, + pub resolved_scope: ScopeResolutionV2, + pub snapshot: Option, + pub coverage: CoverageReportV1, + pub freshness: FreshnessReport, + pub redactions: RedactionReport, + pub retention: EvidenceRetentionWatermark, + pub limits: AppliedLimits, + pub warnings: Vec, +} +``` + +`CoverageReportV1` is plan 01's canonical shared coverage type. No SDK convenience method may discard `meta` by default. A deliberate `into_data()` can consume the response only after making metadata loss obvious in code. + +### 11.3 Truthful partial results + +- Useful rows with one unavailable/stale/locked/redacted shard return success with `!coverage.is_complete()`. +- Each shard/source coverage item declares selected/skipped disposition, requested/captured watermark, schema/capability version, freshness, rows considered/returned when known, and safe reason. +- Zero results plus incomplete coverage is not represented as "no matches". +- Counts declare exact, lower-bound, estimate, sampled, capped, or unknown. +- Search/graph scores declare algorithm/version and are not comparable across profiles unless explicitly normalized. +- SDK iterators aggregate coverage across pages and retain the least-complete state; they do not expose only the last page's metadata. + +## 12. Error and Machine-Actionable Retry Contract + +Errors use the exact RFC 9457-compatible `application/problem+json` `ApiProblem` shape owned by plan 10 §7.2. The public contract IR imports that schema and digest unchanged; generated language SDKs preserve unknown safe problem extensions but define neither a competing struct nor a code/status hierarchy. `ApplicationErrorCode` and retry/restart/candidate/version/operation meaning still come from application/domain, while HTTP alone supplies status and RFC 9457 fields. + +Stable classes include authentication/authorization, scope not found/ambiguous/denied, capability unavailable, invalid request/query, budget/rate/deadline, cursor mismatch/expired/schema/ranking/index/retention, snapshot unavailable, partial-all-unavailable, conflict/expected version/idempotency, operation pending/failed, payload redacted/unavailable, stale client (`client_update_required`, `daemon_restart_required`, `capability_replaced`), stream gap/resync, and safe internal invariant. The stale-client error registry is defined once in this plan's contract IR; plans 09, 10, 12, and 21 use exactly those three codes and mint no variants. + +`RetryDirective` is a tagged union owned by plan 09's `error.rs` (application owns the retry classes) and reproduced here verbatim: + +- `Never`; +- `SameRequestAfter { delay, condition }`; +- `RetryWith { canonical_request }`; +- `RestartPagination { request_without_cursor, reason }`; +- `PollOperation { operation_id, after }`; +- `RefreshAuth { method }`; +- `UpdateClient { minimum_protocol, current_binding, command }`; +- `ResolveScope { candidates, canonical_request_template }`; +- `Resubscribe { snapshot_request, reason }`. + +SDKs implement only declared safe automatic behavior: + +- retry idempotent reads for transport failures and explicit `SameRequestAfter`, under deadline and attempt limits; +- retry commands only with the same idempotency key and only when the problem/operation receipt permits it; +- never silently change scope, consistency, payload visibility, query, or capability; +- surface 426/version, ambiguity, denied, destructive-preview, gap, and retention errors to the caller. + +Error logs and exception strings are secret-scanned and must not echo bearer tokens, raw prompts, query vectors, credential-bearing URLs, sensitive paths, or payload text. + +## 13. Pagination, Cursors, Bulk, Batch, and Asynchronous Operations + +### 13.1 Cursor pages + +Every collection result uses one page envelope, defined here in the contract IR and used unchanged by plan 10's HTTP lists and plan 21's CLI/MCP pages: + +```rust +pub struct CursorPage { + pub items: Vec, + pub next_cursor: Option, + pub truncation: Option, + pub count_semantics: CountSemantics, // exact | lower_bound | estimate | sampled | capped | unknown + pub ordering: OrderingContract, // declared sort keys, direction, and tie-break rule +} +``` + +- All collection endpoints use opaque authenticated cursors. +- A cursor encodes exactly the domain `CursorClaimsV1` binding set (plan 01, codec owned by plan 05): query fingerprint, caller/access digest, canonical scope digest, profile-catalog generation, schema/ranking/index versions, frozen watermarks and per-shard positions, sort cutoff, temporal mode/cutoff, intent-profile version, partial-shard dispositions, and expiry. Interactive cursors use plan-20 `query.cursor.interactive_ttl` (default 15 minutes); export/bulk continuations last their catalog-declared job lifetime. +- Cursor and SSE event-ID authentication uses a persisted profile-local HMAC key set, not the per-launch secret. Each key record is `{key_id (primary key), created_at, activated_at, state: active | retiring | revoked}` stored in the profile catalog shard (plan 02) with at most one `active` key; cursors and event IDs embed `key_id`. Rotation mints a new active key on schedule or on demand; `retiring` keys validate existing tokens for the maximum outstanding cursor/subscription/export lifetime, then become `revoked`. Keys survive server restart, so a restart does not invalidate otherwise-valid cursors; revoking a key invalidates its outstanding tokens with a typed `RestartPagination`/`Resubscribe` directive. Plan 05's cursor codec and plan 10's SSE event IDs consume this one key registry. +- Frozen snapshots referenced by outstanding cursors/subscriptions are pinned against GC/compaction/projection retirement for the cursor's declared lifetime by the store/query retention contract (plans 02/05); a pin that cannot be honored fails with a typed restart reason, never silently different data. +- Page bounds are operation-specific; the default interactive maximum is conservative and documented. +- The server never holds a SQLite read transaction across client think time. +- Cursor invalidation returns an exact restart reason and request; no SDK restarts silently unless the caller opts in. +- SDK pagers support page-at-a-time and async item iteration while exposing page metadata, accumulated coverage, cancellation, and maximum-pages/items guards. + +### 13.2 Typed batch + +`POST /api/v2/batch` accepts at most the declared number/bytes of typed catalog invocations: + +- read-only invocations may run concurrently under a shared deadline/budget; +- each item has its own success/problem envelope and stable caller item ID; +- authorization, scope, cost, and response limits apply per item and to the whole batch; +- no arbitrary URL/method/header forwarding and no nested batch; +- batch never provides transactionality across independent stores/use cases. + +Mutating multi-operation workflows use explicit application commands, not generic batch. Atomicity is available only when one named use case declares one transactional owner. Otherwise each command has a separate idempotency key and receipt. `/api/v2/batch` is an API transport multiplexer over existing cataloged read use cases: it appears in plan 10 §8.1's route inventory and, by design, has no entry in plan 09's use-case inventory. + +`work_items.assign_set` is the named transactional orchestration exception, not generic batch. Its bounded request pins one initiative/plan version, one owner shard, distinct work-item/assignment expected versions, and an explicit route constraint per item (adapter/provider/model/reasoning effort/tools/budget). Application validates the entire set, rejects cross-owner or active-lease-stealing input, and commits all assignments or none; the result includes deterministic per-item validation plus one transaction receipt. Generated Rust/TypeScript/Python SDKs expose `assign_work_item_set`, not a client-side loop over singular assignment calls. + +### 13.3 Bulk and export + +- Bounded NDJSON streams support large canonical row sequences where immediate streaming is useful. +- Large or expensive exports create an asynchronous `ExportOperation`, expose progress/coverage, and finish with a signed, expiring, contained download resource plus manifest/hash. +- Parquet/JSONL schemas are generated from canonical row types and versioned in the manifest. +- Client disconnect cancels uncommitted read work. Durable exports/jobs continue only when explicitly requested and remain pollable. +- Exports never accept an arbitrary output path through the public API. + +## 14. Streaming and Change Subscription + +The official live contract is snapshot plus typed delta over SSE: + +1. `POST /api/v2/subscriptions` submits the sensitive typed canonical query (including its explicit scope) and returns a session-bound subscription ID, initial snapshot reference, expiry, and stream path. +2. `GET /api/v2/subscriptions/{id}/events` emits the matching snapshot first, then ordered deltas/progress/coverage/operation/gap events. +3. `Last-Event-ID` uses an authenticated opaque event cursor bound to subscription, authorization, protocol, and sequence. +4. `POST /api/v2/subscriptions/{id}:revoke` invokes canonical `subscriptions.revoke`; disconnect never substitutes for the idempotent audit/release receipt. + +Rules: + +- query text and tokens never enter the URL or event ID; +- heartbeats carry no semantic sequence; +- finite replay retention is declared; +- duplicate/out-of-order delivery can be applied idempotently; +- only semantically idempotent updates may coalesce; +- terminal operation, removal, coverage, gap, policy/version, and audit events never coalesce away; +- bounded per-connection frames/bytes, principal/global connection caps, and slow-client termination prevent memory growth; +- an unrecoverable gap emits `resync_required` and closes; SDKs fetch a new snapshot only under explicit reconnect policy; +- auth revocation, scope loss, privacy change, or protocol cutoff terminates the stream with a typed reason; +- SDK streams expose snapshot, delta, progress, heartbeat visibility option, gap, reconnect, and terminal events rather than hiding them behind an untyped callback. +- Task subscriptions are ordinary `TraceQueryV1` read-model subscriptions. Each delta carries the causing canonical task-journal sequence range and projector watermark; there is no `/task-events` endpoint, task-specific cursor, or client-side merge of an outbox/adapter stream into task truth. + +## 15. Graph-of-Graphs API + +The public graph surface treats code, Git, threads, sessions, Turns, agents, workflows, goals, memory, skills, automation, time, and delivery as lenses over one evidence graph, not unrelated endpoint-specific node models. + +### 15.1 Typed operations + +- `POST /api/v2/graph/neighborhood` — bounded expansion from entity/anchor roots. +- `POST /api/v2/graph/path` — bounded evidence path with allowed edge/entity kinds and maximum depth/cost. +- `POST /api/v2/graph/subgraph` — query-driven subgraph with LOD and cluster limits. +- `POST /api/v2/graph/impact` — downstream/upstream effect paths with confidence/evidence. +- `POST /api/v2/graph/diff` — compare frozen graph snapshots, refs, sessions, policies, or time windows. +- `POST /api/v2/entities:batch` — batch hydrate stable IDs already returned by another operation; no duplicate graph-only hydration use case. +- `POST /api/v2/timeline/events` and `/timeline/density` — temporal projection of the same entities/relations. + +### 15.2 Node and edge contracts + +Every node includes stable typed ID, kind, safe label, time validity, owning/related scopes, availability, evidence summary, payload-access state, and retrieval anchor. Every edge includes kind, direction, valid/transaction time, evidence IDs, confidence/trust class, inference/projector version, and contradiction/uncertainty state. + +The API distinguishes: + +- observed relationship; +- provider-declared relationship; +- deterministic projection; +- heuristic/inferred correlation; +- user/agent annotation; +- unresolved candidate. + +Graph results include exact membership or declared sample/cluster membership, edge aggregation semantics, LOD/layout/community algorithm version, expansion cursor, selected watermarks, and partial coverage. A visualization cluster is not serialized as a factual domain entity. + +### 15.3 Safety and cost + +- Query declares allowed node/edge kinds, direction, depth, maximum nodes/edges/paths, time range, and payload fields. +- Server estimates and enforces cost before expansion; high-fanout edges require aggregation or explicit narrowed continuation. +- Payload hydration is separate from topology and independently authorized/redacted. +- No arbitrary Cypher/SQL/GraphQL string is accepted. +- Cross-project traversal respects every source privacy domain and reports denied/redacted boundaries without leaking existence beyond authorization. +- Code graph nodes bind repository/worktree/ref/code-snapshot identity; the base checkout never substitutes for a requested parallel worktree. + +## 16. Search, Hint, and Policy Replay APIs + +Replay endpoints are official but safe by construction. Their application use cases are read-only and have no command binding. + +### 16.1 Replay modes + +- `exact_deterministic`: resolve the exact executable evaluator, schema, config, policy, catalog, index/model, project/memory/skill, and prompt-template digests. +- `recorded_result`: inspect exact historical inputs/candidates/results/payloads when executable artifacts are unavailable. +- `current_best_effort`: run the current evaluator against explicitly selected historical/synthetic inputs and label all substitutions/missing evidence. + +Missing artifacts yield incomplete fidelity, never silent approximation. + +### 16.2 Hint replay + +`POST /api/v2/labs/hints:replay` accepts a stable message/Turn/session/hook anchor or an explicit synthetic input, selected policy bundle, scope, candidate catalog, and replay mode. It returns: + +- normalized safe input facts and redactions; +- all candidate capabilities/hints with features/scores; +- eligibility/privacy/availability decisions; +- repetition/cooldown/token/latency budget decisions; +- suppressions with stable reasons; +- exact rendered payload reference only when authorized; +- historical delivery/outcome evidence kept distinct from candidate prediction; +- current-versus-historical diff; +- artifact/fidelity manifest and retrieval anchors. + +Replay never injects a hint, invokes a tool, publishes presence/claim, modifies memory/fact trust, increments usage/counters, records an acted outcome, or emits live analytics. A separately named export/share command is required to persist a replay artifact. + +### 16.3 Search replay and evaluation + +`POST /api/v2/labs/search-quality:replay` and `/api/v2/labs/search-quality:compare` expose the pipeline in plan 15: + +- exact/phrase/lexical/fuzzy/entity/sparse/dense/graph/recency candidate lanes; +- dedupe/representative/group membership and hidden counts; +- per-stage caps, component ranks/scores, fusion, diversity, reranker, and final explanation; +- index/model/corpus/profile versions and selected watermarks; +- coverage, no-answer decision, latency/resource measurements; +- relevance judgments only when authorized and never as hidden live labels. + +Experiments can compare named retrieval profiles over a frozen local evaluation manifest. They cannot silently switch a live agent's retrieval profile, write judgments, or send private queries to a network model. Publishing and activating a profile use the direct immutable/CAS commands in §8.2 with locked gates and audit; prior versions remain available for an explicit later activation, not a fictional mutation rollback. + +## 17. Commands and Mutation Safety + +The official API may expose the broad writable capability surface, but direct-agent credentials default to read-only. + +Every command request includes: + +- stable use-case ID; +- explicit canonical scope and declared owner scope for created state; +- idempotency key; +- expected aggregate/config version; +- operation-specific inspection or confirmation digest where meaningful; +- authorization grant and approval provenance; +- bounded deadline/resource policy; +- optional client correlation ID. + +Every result includes effect/audit receipt, current/new version, compensation/rollback availability, and either terminal output or durable operation/workflow ID. + +Destructive or broad non-curation operations such as wipe, retention deletion, payload GC, migration cutover, external delivery, policy activation, and automation enablement require a capability-specific grant and their cataloged operation-specific inspect/plan plus confirmation contract. A generic `write` token is insufficient. + +Merged #425's split-store consolidation is one such operator workflow. The public/admin contract exposes typed inspect/plan/start/status/resume/recover methods over two explicit source identities, path-plus-file/inode holder/freeze/reservation evidence, backup/staging/verification/cutover receipts, deterministic confirmation, per-table/artifact dispositions, and exact recovery. SDKs never accept arbitrary raw store paths, implement merge logic, or automatically retry an uncertain start. These methods appear only on `AdminClient`; task-executor and curation-service grants cannot discover or invoke them. + +Fact/memory/managed-skill/profile curation is not exposed as item-level approve/apply/install/rollback endpoints. A dedicated least-privilege curation service grant plus versioned autonomy configuration authorizes the application worker to execute only owned, policy-eligible effects after transactional revalidation; every effect/outcome/recovery is audited. Public clients can read status/history/decisions/outcomes, configure policy, pause/resume/run-now, pin/protect/exclude, and submit feedback. Unsafe/foreign/out-of-authority candidates are automatically rejected/deferred/quarantined, never converted into a human approval endpoint. + +Move-symbol is a first-class two-operation edit workflow, not a generic filesystem mutation: generated clients expose read-shaped `code.move_symbol.inspect` and separately authorized `code.move_symbol.commit`. Inspect returns exact source/destination/snapshot/version, impact classes, proposed imports, and a confirmation digest without writing; commit consumes that digest, revalidates both endpoints, requires the repository/worktree edit grant, and returns commit/recovery/reindex receipts with no automatic caller rewrite. Raw paths/source/diffs use protected/eligible fields and never enter URLs or client logs. + +| Operation | HTTP | Rust | TypeScript | Python | +|---|---|---|---|---| +| `code.move_symbol.inspect` | `POST /api/v2/code/move-symbol:inspect` | `inspect_move_symbol` | `inspectMoveSymbol` | `inspect_move_symbol` | +| `code.move_symbol.commit` | `POST /api/v2/commands/code/move-symbol:commit` | `commit_move_symbol` | `commitMoveSymbol` | `commit_move_symbol` | + +SDKs separate `ReadClient` and `AdminClient` surfaces where the language permits. Mutation methods do not appear on a read-only typed client. Raw HTTP still enforces the same server-side grant. + +## 18. Authentication, Local Trust, Privacy, and Secret Handling + +### 18.1 Transports + +- Prefer a user-owned Unix-domain socket with OS ownership/mode checks for local nonbrowser clients, plus application authentication. Plan 10 builds the socket listener and its peer-credential checks (plan 10 §10.1); this plan owns UDS conformance (Section 24). +- Loopback HTTP binds only exact loopback by default and enforces strict Host/Origin/forwarded-header policy. +- Browser uses per-launch bootstrap, secure session cookie, and CSRF token. +- Agent/SDK uses a bearer token or local credential-provider handshake. Tokens never appear in URLs, process titles, command history examples, OpenAPI examples, or logs. +- Non-loopback bind requires a future explicit deployment profile with TLS, stronger identity, documented threat model, and separate review; changing the address flag alone is insufficient. + +### 18.2 Credential model + +Tokens are: + +- random, hashed at rest, user/profile/instance bound; +- named by safe token ID for audit/revocation; +- time-bounded by default; +- constrained by read/preview/mutate/admin capability grants; +- constrained by scope selectors and sensitivity/payload grants; +- optionally process/installation identity bound where supported; +- revocable immediately with stream/operation implications declared. + +The per-launch bootstrap bearer of plan 10 §10.2 is not a parallel credential model: it is the bootstrap credential whose only permitted operation is `auth.tokens.create` (plan 09 §10), minting the initial admin-class token in this registry. Every operating credential is a registry token. + +The CLI prints a token only through an explicit secure creation flow and warns about shell history/agent context. Prefer delivering credentials by inherited file descriptor, OS keyring/credential helper, or `0600` file reference instead of environment variables for long-lived automation. + +### 18.3 Data privacy + +- Authorization is checked at capability, scope, entity, edge, payload, field, export, and stream stages. +- Topology visibility does not imply payload visibility. +- Secret-classified content never enters FTS/vector indexes, API examples, problems, telemetry, cursors, anchor labels, source maps, or conformance fixtures. +- Prompt/tool/provider sanitized-native payload access is an explicit sensitivity grant and every access is audited. Plaintext forensic access, when protected retention exists, is a distinct elevated quarantine workflow and never a normal entity/message/session/graph route. +- Durable graph-resident facts and memory are user data; backup, migration, export, delete, and corruption APIs never treat the whole graph database as disposable derived state. +- Replay/sandbox inputs are retained only when a separate explicit save/export command succeeds. +- Every endpoint documents retention, redaction, and deletion consequences. +- Content-bearing request fields enter as bounded `Unclassified` and cross the application sanitizer; SDK/runtime code never marks raw strings or JSON trusted. Responses, problems, events, examples, anchors, and generated docs contain only plan 18 sink-eligible wrappers or explicit redacted/denied/unknown states. +- `PrivacyProtectionStatusV1` reports configured policy, effective non-disableable floor, source/sink/detector coverage and versions, last verified scan, legacy/unscanned/unknown counts, and restore eligibility. No SDK property named merely `redaction_enabled` is generated, and lossy-row existence is not status evidence. +- Bounded failures, decoder exceptions, `Debug`/`Display`, and automatic retry diagnostics never retain or echo the request body. They preserve safe codes/IDs/directives and discard candidate content after decoding. + +## 19. Limits, Fairness, and Resource Budgets + +Limits are cataloged and returned by `/meta` and capability discovery: + +- maximum request/compressed/decompressed bytes, JSON depth, headers, URI, batch items, page items, graph nodes/edges/depth, timeline bins, payload bytes, export bytes, and stream queues; +- per-principal concurrent reads, streams, exports, jobs, and mutations; +- token-bucket request/query-cost budgets by capability class; +- absolute server deadline plus client-requested shorter deadline; +- selected-shard and representation/vector/model budgets; +- fair scheduling across parent/subagents and profiles so one broad query cannot starve hook capture or interactive queries. + +429/413/422/budget responses declare applied limit, safe current usage when available, reset/retry time, and legal narrowing actions. They never recommend broadening scope or dropping privacy filters merely to succeed. + +Hook hot paths and capture writers do not call the public HTTP API. Public API load is isolated from append durability and bounded so replay/search experiments cannot delay provider hooks. + +## 20. SDK Design + +### 20.1 Common behavior + +All SDKs provide: + +- endpoint discovery and explicit client construction; +- credential-provider abstraction with redacted debug output; +- protocol/catalog/schema handshake; +- typed capability and scope resolution; +- one method per public use case plus generic catalog invocation only for forward-compatible tooling; +- response envelopes with metadata preserved; +- cancellable request deadlines; +- page and async-item iteration with maximum guards; +- SSE reconnect/gap/resync primitives; +- operation polling with backoff bounded by server directives; +- typed problems and retry directives; +- stable anchor parsing/resolution; +- user-agent containing SDK/runtime version but no project/query identity; +- optional OpenTelemetry propagation with payload-free defaults. + +The generic invocation API accepts a `UseCaseId` and schema-validated typed/JSON value for exploratory agents. It still passes catalog authorization/cost/effect checks and returns canonical envelopes. Generated named methods remain preferred and are the only methods shown in normal docs. + +### 20.2 Rust + +- `tracedecay-client` exposes async traits and a default client runtime that imports only generated public request/response/event schemas, canonical `ApiProblem`, and its own transport/pager/stream runtime. It has no dependency on domain, store, application, or server implementation crates and reaches TraceDecay only through an injected transport at runtime. +- Support Unix socket and loopback HTTP transports behind features. +- Generated public contract/schema module is public; hand-written client/pager/stream/operation code is small and reviewable. +- Errors preserve `ApiProblem`; `Debug`/`Display` redact credentials and sensitive bodies. +- Compile examples and MSRV/toolchain policy are release gates. +- Optional in-process transport exists only as a test/root-composition adapter implementing the public client transport trait; that external adapter invokes the same application contract without adding any application/server dependency to the client crate or defining a different semantic API. + +### 20.3 TypeScript + +- Publish an ESM-first typed package for Node and browsers, with explicit browser auth constraints. +- Use `fetch`, `AbortSignal`, async iterators, and a tested SSE implementation that can send required auth safely. +- Preserve 64-bit counts as `bigint` or validated string-backed named types where necessary. +- Runtime decoding validates discriminators and reports schema/protocol mismatch rather than accepting malformed JSON. +- Browser package cannot read local discovery/token files; dashboard bootstrap supplies an authenticated client. +- Node package supports the local socket transport when the runtime permits it. + +### 20.4 Python + +- Publish typed synchronous and asynchronous clients with Python version policy declared before implementation. +- Use generated immutable models plus a small HTTP/socket runtime; ship `py.typed`. +- Provide sync/async pagers, context-managed streams/operations, cancellation/timeouts, and typed exceptions retaining `ApiProblem`. +- Avoid import-time endpoint discovery or network calls. +- Validate large integers, discriminated unions, timezones, and unknown enum behavior in contract tests. + +### 20.5 Generation quality + +Do not check in an enormous generic generator runtime without review. Generate stable models, endpoint descriptors, and method signatures from the contract IR; maintain compact language-native transport/pagination/stream runtimes by hand. Generated diffs are deterministic and human-reviewable. + +SDK release versions declare the exact supported protocol range. Server, CLI, MCP plugin, dashboard, and SDK release automation publishes the compatibility manifest atomically or fails before partial release. +The trusted release job also compares changed files with the generated allowlist, rejects tracked ignored/omitted contract artifacts and dirty generation, builds/packages SDKs from clean inputs, and secret-scans every generated derivative before publication. + +## 21. CLI, MCP, Dashboard, Plugin, and Tool Integration + +- CLI, MCP, and dashboard bindings are generated/audited from the same catalog and application schemas. +- Server-side CLI/MCP adapters call `tracedecay-application` directly; they do not make recursive loopback HTTP calls. +- External plugins and agents use the official HTTP/SDK contract rather than internal databases or unstable root modules. +- MCP human-facing defaults remain compact Markdown; explicit JSON mode uses the canonical typed view model and preserves all machine fields. HTTP/SDK always use canonical machine JSON. +- Markdown and JSON render from the same typed application view, with parity tests for missing registries, active markers, repeated basenames, limits, truncation, and coverage. +- Tool catalog entries link directly to API docs and SDK examples. API discovery links back to CLI/MCP bindings so an agent can choose the cheapest available surface. +- Host integrations handshake catalog/protocol digest. If an installed plugin is stale, it receives one current restart/update/replacement instruction; no dual namespace or legacy behavioral shim. +- `tracedecay tool --args ...` remains a useful shell fallback but is not the only direct machine API. +- Plugin authors receive a minimal integration guide, conformance fixture runner, synthetic sandbox, and version matrix. + +## 22. Documentation, Examples, and Sandbox/Playground + +### 22.1 Documentation requirements + +The official docs contain: + +- a five-minute read-only quickstart for curl, Rust, TypeScript, and Python; +- endpoint/credential discovery without secret leakage; +- the scope mental model with multi-repository/worktree examples; +- coverage/freshness/partial-result and count semantics; +- pagination, stream resume/gap, operation polling, and retry recipes; +- stable retrieval anchors and citation examples; +- Graph-of-Graphs traversal and LOD/cost rules; +- safe search/hint replay examples; +- command preview/idempotency/authorization examples; +- all stable error codes and retry directives; +- version compatibility and cutoff behavior; +- security/privacy/retention/export guidance; +- generated reference for every public capability and SDK method. + +Examples use a generated synthetic profile containing multiple repositories, two worktrees of one repository, parent/subagents, sessions/Turns, a workflow, Git branch/PR, code changes, memory/facts, automation, hints, and known partial/stale stores. No local user data is committed. + +### 22.2 Interactive API explorer + +Serve an authenticated API explorer from the local docs endpoint (plan 10's static_app serves it under `/docs` with the same loopback auth/CSP/bootstrap rules, plan 10 §13): + +- schema browsing and synthetic examples need no mutation grant; +- "try" uses the current authenticated session and clearly displays canonical request, scope, expected cost, and response metadata; +- mutation operations open in preview mode and cannot apply from generic reference pages without capability-specific confirmation; +- tokens are never saved to local storage, URL, docs source, or generated curl snippets; +- response panels show coverage/freshness/redaction/limits and problems, not only `data`; +- an anchor can open the dashboard inspector under reauthorization. + +### 22.3 Safe sandbox + +Provide a fixture-backed sandbox process/profile: + +- deterministic synthetic corpus and frozen clock; +- no access to real profile stores, credentials, network providers, GitHub mutations, or host hooks; +- resettable state and seeded error/partial/gap/version scenarios; +- same OpenAPI/protocol and SDK clients as production; +- read-only hint/search replay by default; +- conformance runner can launch it hermetically. + +The dashboard Hint/Search/Coordination/Query labs use application use cases, not a special undocumented API. The API explorer and sandbox link to those richer visual labs when available. + +## 23. Observability and Audit + +Every API request records safe operational telemetry: + +- request/correlation ID, use-case/binding ID, server/protocol/catalog versions; +- authenticated principal/token ID class, never token value; +- canonical scope kind/count and privacy domain digest, not sensitive paths/query text; +- deadline/budget/limit class; +- rows/bytes/shards and complete/partial/redacted state; +- latency by auth/extract/application/serialize/queue, plus cancellation/retry/error code; +- stream connections, resume distance, coalescing, gaps, slow-client closes; +- SDK name/version and transport; +- command idempotency/effect/operation/audit receipt IDs. + +OpenTelemetry spans and `Server-Timing` expose safe stage timings. Trace propagation is allowlisted; untrusted baggage is rejected. Logs, traces, metrics, and error aggregations pass secret and high-cardinality review. + +Product analytics distinguish capability discovery, invocation, useful result continuation, error/retry, and abandonment. They do not treat API call volume as success, and replay/debug calls do not count as live hint/tool outcomes. + +An API Observatory view reports protocol/client versions, catalog parity, endpoint health, latency/error/partial distributions, rate-limit pressure, stream gaps, SDK adoption, stale clients, and conformance status with explicit denominators/horizons. + +## 24. Conformance, Evaluation, and Release Gates + +### 24.1 Semantic parity matrix + +For every use case, run a canonical fixture through each applicable path: + +```text +application in-process +HTTP JSON +Rust SDK +TypeScript SDK +Python sync SDK +Python async SDK +CLI JSON +MCP JSON +dashboard client +export rows +SSE initial snapshot +``` + +Compare canonical semantic JSON after removing only declared transport fields such as request timing. Verify identity/order, scope, snapshot/watermarks, coverage/freshness/redaction/retention, evidence/confidence, ranks/explanations, cursor claims, anchors, errors/retries, replay fidelity, command receipts, and operation state.

Verdict on the current system + +TraceDecay already contains useful redaction code, but it is not one reliable redaction system. + +The strongest current path is LCM raw-message ingest in `src/sessions/lcm/raw.rs`: + +- `prepare_message` calls `redact_sensitive_text` before payload externalization and before the canonical session projection is written. +- Text redactors cover API-key assignments, bearer tokens, password assignments, and complete private-key blocks. +- Structured JSON traversal can redact values under sensitive-looking keys. +- Redaction metadata records patterns and irreversible/lossy status. +- Tests prove enabled redaction prevents plaintext from reaching the LCM/session FTS projection. + +The critical problem is `ingest_config`: `sensitive_patterns_enabled` defaults to `false`, and the setting comes from each message’s metadata. Current provider adapters do not establish one mandatory profile policy. In ordinary ingest, the same storage path therefore preserves content unchanged and makes it searchable. Existing status reports infer “redaction enabled” from whether any lossy rows exist, not whether a protective policy is configured and complete. + +Other protections are separate and inconsistent: + +- `src/memory/hygiene.rs::detect_secret_like` rejects secret-like fact creates/updates and suppresses memory injection/digests. It is a detector/reject guard, not a general redactor. +- Project-list/context renderers omit credential-bearing Git remote URLs, but the registry and every other output path do not share a universal safe-text contract. +- Current Codex structured tool-event projection stores byte counts rather than raw tool arguments/output in FTS text; the historical bug and fix must remain a regression fixture. +- Claude `redacted_thinking` and Codex encrypted reasoning are respected, but provider-native redaction is not equivalent to credential scanning. +- Memory curation detects secret-like legacy facts but currently includes a 200-character `truncated_content` field in its candidate, which can reveal the exact value it is recommending for deletion. +- The LCM placeholder contains plaintext length and, for most classes, a 16-hex unkeyed SHA-256 prefix. That leaks equality and enables dictionary testing for weak secrets. +- There is no complete inventory/scan/quarantine/rebuild process for secrets already present in session rows, FTS, summaries, vectors, facts, code graph snippets, analytics, caches, exports, WAL, backups, fixtures, or release artifacts. + +Conclusion: preserve useful current behavior as fixtures, then replace it with one fail-closed classification and sanitization boundary. “Opt-in lossy LCM redaction” is not an acceptable V2 default. + +The implementation audit also found concrete bypass classes that the migration cannot hide behind the generic word “content”: + +| Current seam | Observed gap | Required V2 disposition | +|---|---|---| +| Hermes activity/session projection | A projection-only path can bypass the normal LCM preparation/redactor. | Every provider and legacy importer must produce `Unclassified` and cross the same capture sanitizer before any observation, projection, or compatibility read becomes serving. No projector accepts provider-native content directly. | +| Hook analytics | The full command can be persisted twice through separate analytics fields. | Analytics accepts only catalog-safe IDs/classes/counts and sanitization receipt refs; command/query/prompt/tool text is structurally unrepresentable, including compatibility analytics. | +| Bounded MCP failure rendering | A bounded/truncation failure reason is returned without secret scanning. | Application errors and retry directives use `LogSafeText`/`CatalogSafeText`; transport-generated detail is sanitized before serialization and cannot embed a rejected input or payload excerpt. | +| LCM summaries | Summary output does not pass a complete post-model scan. | Models receive only `PromptEligibleText`; every returned summary is `Unclassified` again, rescanned, and converted to `SearchEligibleText` before storage/indexing. | +| Response handles | Payloads are written with direct filesystem writes. | Response handles are migration-only and store only sink-eligible bytes through a private atomic writer; V2 paging uses authenticated cursors and durable citations use `RetrievalAnchorId`/`RetrievalAnchorRecordV1`. | +| LCM backup/copy | Backup paths can copy store bytes directly. | Backup/restore uses privacy manifests, isolated staging, current scanner versions, projection rebuild, and promotion receipts; a direct serving `copy` path is prohibited. | +| Dashboard server and plugin views | Raw content/metadata can be rendered; arbitrary `--host` can expose an unauthenticated surface. | Plan 10 loopback authentication/Host/Origin/CSRF/CSP is mandatory; plan 11 consumes only sanitizer-eligible application views. Non-loopback bind is rejected in the first V2 default. | +| Memory facts/entities | Tags, entity labels, source fields, metadata, and the V11 legacy direct-insert/vector path are not covered uniformly. | Every fact field and legacy row is sanitized before entity extraction, vectors, FTS, trust, or projection; the V11 path is import-only, non-serving, and rebuilt from sanitized authority. | +| Redaction status | “Enabled” is inferred from the existence of a lossy row. | Status reports configured policy, effective safety floor, source/sink/detector coverage, scanner version, legacy unknowns, and last verified scan independently; historical row existence is never configuration evidence. | +| Credential-shaped tests | Nine existing fixtures resemble live credential formats closely enough to trigger repository scanners. | Replace them with reserved/invalid scanner-safe canaries, keep structural detector coverage, and require zero findings across source plus every generated derivative. | + +These are named regression rows in PR 2B/7A/10A/24H/33A. A generic “secret scan passed” without one result per seam is incomplete. + +## 2. Historical and current evidence anchors + +| Anchor | Evidence | Required regression | +|---|---|---| +| `session:agent-a0142b3f24b97b5de` | 2026-07-09 adversarial audit confirmed unredacted Codex tool preview content reached FTS on the then-audited master and separately confirmed `sensitive_patterns_enabled=false`. It recommended a source-ingest redaction contract rather than reusing memory’s reject-only detector. | Tool arguments/output, messages, metadata, replay fields, and provider additions pass one mandatory sanitizer before any TraceDecay persistence/search projection. | +| `session:agent-adbbfd3b92fec0808` | Parallel audit aggregation preserved the same security finding and evidence. | Copied audit traffic clusters under one canonical incident and does not inflate evidence strength. | +| `session:019ee5d9-6b70-7e81-b9d2-804c61fc4bea` | Live status explicitly reported Codex LCM redaction disabled. | Status distinguishes configured policy, coverage, findings, sanitized rows, quarantined rows, legacy/unscanned data, and detector version. | +| `session:1172143d-d85c-4cd8-aeac-3d4af50dc7e8` | Earlier LCM parity work added private-key and quoted-password redaction tests while retaining opt-in behavior. | Import all redactor fixtures, but change policy ownership/default and add every forbidden sink. | +| `session:bb6a2927-0ae6-46ed-9aed-b2e5928eb20a` | Parity review found quoted multi-word password behavior diverged across implementations. | One canonical detector/redactor implementation and conformance corpus serve every provider/transport. | +| Current planning parent `session:019f4906-a411-7a11-ad3f-0d58deb0e847` | Plan/corpus secret scan found default scanner false positives on private-key markers; parsed-value validation rejected a serialized-JSON cross-field URL alert; conservative sanitization was required. | Parse structured fields before scanning; never run permissive credential regex across serialized record boundaries; report no candidate content. | + +The private chronological research corpus remains outside Git and mode `0600`. Its sanitized canonical files contain 34,333 native `role=user` rows and 9,969 best-effort human rows, including a manifest-labeled 28-record root-rollout fallback after supported replay failed; `gitleaks 8.30.1` reports zero findings after conservative redaction. The corpus is still not a fixture and must never be ingested into a TraceDecay test/profile store. + +## 3. Non-negotiable security invariants + +1. Secret or unadjudicated secret-like plaintext never enters any general-purpose TraceDecay store, index, prompt, output, cache, fixture, export, log, or package. +2. Every content-bearing input crosses one versioned sanitization boundary before persistence or agent/API exposure. +3. Scanner failure, timeout, unsupported encoding, incomplete structured parsing, or unknown policy fails closed: persist a non-content quarantine/coverage skeleton, not plaintext. +4. Provider/source metadata can request stricter handling; it cannot disable the profile’s mandatory secret policy. +5. Raw provider transcript/source remains provider-owned. TraceDecay stores a source locator/digest and sanitized projection by default, not a second raw secret copy. +6. Optional forensic retention uses a separate encrypted quarantine/key domain, is never indexed or exported, requires explicit user policy/access, and has short retention. +7. Detector findings, logs, analytics, errors, and UI never include the candidate value, prefix/suffix, surrounding text, raw URL, or unkeyed candidate digest. +8. Public redaction markers reveal class and an opaque receipt ID only. They do not reveal exact length, byte count, source substring, or cross-domain equality. +9. False-positive adjudication is scoped to a keyed fingerprint, rule version, source field/context class, owner, reason, and expiry. It never contains the secret and never disables a detector globally by accident. +10. A detected credential is assumed compromised. TraceDecay explains rotation/revocation as the first remediation step; deletion/redaction alone is not presented as sufficient. +11. “Zero findings” is claimed only with complete named coverage and scanner/policy versions. Locked, skipped, corrupt, incompatible, too-large, timed-out, and unsupported inputs remain explicit unknowns. +12. V1 rollback stores/backups cannot reintroduce unsafe content. They are rescanned/migrated in isolation before becoming eligible for restore. + +## 4.

Domain contracts + +Plan 01 §7.5 is the sole definition of the closed `DataSensitivity` enum. This security plan owns its meaning, transition rules, and sink eligibility, while the domain crate publishes that exact shared type. The same module adds opaque, validated detection and receipt types: + +```rust +pub struct DetectionV1 { + pub detection_id: DetectionId, + pub rule_id: DetectorRuleId, + pub rule_version: DetectorRuleVersion, + pub class: SecretClass, + pub confidence: DetectionConfidence, + pub field_path: ProtectedFieldPath, + pub span: ProtectedSpan, + pub fingerprint: KeyedSecretFingerprint, + pub evidence: DetectionEvidenceClass, +} + +pub struct SanitizationReceiptV1 { + pub receipt_id: SanitizationReceiptId, + pub source_observation_id: ObservationId, + pub policy_digest: PrivacyPolicyDigest, + pub detector_set_digest: DetectorSetDigest, + pub parser_digest: ParserDigest, + pub input_domain: PrivacyDomainId, + pub input_fingerprint: KeyedPayloadFingerprint, + pub output_digest: SanitizedOutputDigest, + pub findings_by_class: std::collections::BTreeMap, + pub structured_fields_scanned: u64, + pub raw_fallback_used: bool, + pub decode_depth: u8, + pub completeness: ScanCompleteness, + pub occurred_at: UtcMicros, +} +``` + +Content taint types enforce sink eligibility: + +- `Unclassified` can exist only inside capture/parser memory and cannot serialize to a repository interface. +- `Classified` carries sensitivity and detector receipt but is not automatically indexable. +- `Sanitized` proves the mandatory detector/policy version and contains no retained candidate bytes. +- `CatalogSafeText`, `SearchEligibleText`, `PromptEligibleText`, `ExportEligibleText`, and `LogSafeText` require explicit checked conversions from `Sanitized`. +- `ProtectedSecretRef` points only into the isolated quarantine service; it cannot implement display/serialize-to-public-envelope. +- Repository traits accept eligible types rather than `String` for content-bearing fields. + +Raw `String`, `serde_json::Value`, and byte slices are forbidden at the application-to-store, projector-to-index, and application-to-transport content ports. Architecture lint/compile-fail tests enforce this boundary. + +This is the single authoritative content-safety type system for plans 01–12 and 15–17. Those plans may define domain-specific view models, but every content-bearing field must be one of these eligible wrappers or a typed redacted/denied/unknown state; they must not introduce a parallel `SafeText`, `AuthorizedContent`, or “already trusted JSON” bypass. `RetrievalAnchorRecordV1`, cursor, status, capability, error, and operation envelopes contain opaque identifiers and safe metadata only and are subjected to the same output-sink check. + +## 6. Privacy policy ownership and precedence + +`PrivacyPolicyV1` is profile-owned, versioned, signed/digested, and evaluated before content persistence: + +1. Non-disableable built-in safety floor. +2. Profile policy. +3. Project/privacy-domain policy that may strengthen but not weaken the floor/profile. +4. Source/provider policy that may add formats or stricter retention. +5. One-record metadata that may request quarantine/drop but cannot disable scanning. + +The current pattern—reading `sensitive_patterns_enabled=false` from message metadata—is retired. Migration interprets legacy metadata only as provenance explaining old behavior. + +Policy chooses: + +- detector set/version and confidence thresholds. +- field/source exclusions that remain structurally scanned. +- normal/sensitive/reasoning/secret retention. +- drop versus marker versus protected-quarantine action. +- maximum field/record/archive/decode sizes and time budgets. +- optional custom detector manifests. +- authorized quarantine roles and audit requirements. +- false-positive allow decisions and expiry. + +No user option makes secret plaintext searchable. The user may choose “drop completely,” “sanitized marker only,” or “marker plus protected short-lived quarantine.” + +## 7. Structured parse-before-scan pipeline + +The current research false positive demonstrates why serialized-envelope scanning is unsafe. One regex over a JSONL line can match characters from different JSON fields and fabricate `scheme://username:password@host` evidence. + +Required pipeline: + +1. Frame one provider-native record with strict byte/size/deadline limits. +2. Parse the provider/event schema and classify fields by semantics. +3. Traverse string/byte leaves independently with a canonical protected field path. +4. Decode bounded known wrappers only inside that field: JSON string layer, URL percent encoding, base64/base64url when high-confidence metadata or detector requests it, and supported archive members under budgets. +5. Normalize Unicode for detector comparison without changing the source span mapping. +6. Run structured key/pair/format detectors, then content/prefix/context/entropy detectors. +7. Merge overlapping detections deterministically by severity/specificity; preserve all rule evidence in the protected receipt. +8. Replace spans in the typed field; validate that no candidate bytes survive. +9. Re-serialize the sanitized structure canonically. +10. If parsing fails, run a bounded raw-field fallback inside the record only. A fallback cannot scan across records and is marked incomplete when truncation/encoding prevents proof. + +Chunk boundaries retain a bounded overlap window for multiline/token-split formats. The scanner never concatenates unrelated messages, fields, files, rows, or shards merely to increase recall. + +## 8.

Optional forensic preservation is explicit: + +- Separate directory/store and encryption key domain from normal blobs. +- Random blob ID; no cross-domain content-addressed dedupe. +- Per-record data-encryption key wrapped by an OS-keyring/profile key-encryption key. +- Authenticated encryption includes profile/domain/source/receipt/policy as associated data. +- Mode `0600`/private directory at first syscall; no plaintext temp file, SQLite value, WAL, log, or crash artifact. +- No FTS/vector/summary/fact/graph/export/backup with normal data. +- Access requires exact finding, explicit role, reason, confirmation, and audit; API/SDK agent tokens are denied by default. +- Initial TTL 24 hours; user hold is explicit, visible, time-bounded, and reviewed. +- Expiry destroys the wrapped data key and blob; non-content tombstone/receipt remains. +- Quarantine backup is disabled by default. If enabled, it is separately encrypted/restricted and restore-scanned in isolation. + +If the OS keyring is unavailable or locked, quarantine retention fails closed to sanitized-only/drop; it never stores plaintext “temporarily.” + +## 11. Sink firewalls by domain + +### 11.1 Sessions, LCM, tools, goals, and workflows + +- Sanitize every message/content part, tool argument/result/error, visible summary, goal/task, inter-agent message, workflow input/output, and replay field before observation persistence. +- Preserve the provider-native source locator as a privacy-domain-bound digest, offset, keyed source fingerprint, and sanitized structure; do not copy raw content or an unkeyed checksum into metadata. +- Parent/subagent prompt copies reuse sanitized entities/refs, never rescan a concatenated serialized envelope. +- Summary/compression models receive only `PromptEligibleText`; summaries are rescanned before storage. +- LCM/session FTS indexes only `SearchEligibleText`. +- Status reports policy configured/effective, adapter/detector coverage, last full scan, sanitized/quarantined/legacy-unscanned counts, and unknowns separately. +- Hermes/legacy projection-only importers and the V11 memory migration path are source adapters, not trusted projectors: they must cross the sanitizer before canonical append and cannot insert serving rows/vectors directly. +- Response-handle payloads and LCM backups use the private store/backup ports with eligible bytes, manifests, atomic publication, and restore scanning. Direct `fs::write`/`fs::copy` of content-bearing serving artifacts is a forbidden-import regression. + +### 11.2 Code graph, Git, diagnostics, and delivery + +- Scan repository text/string literals/config/diffs/commit messages/diagnostics/logs before storing snippets, graph labels, FTS, or embeddings. +- Ignore policies reduce input scope but cannot make included secret content indexable. +- Secret files/fields/lines create redacted node/coverage markers and source locators; structural code identity may remain if it contains no candidate bytes. +- Git remote/userinfo is parsed and credentials removed before catalog identity, matching, rendering, or analytics. +- Live GitHub/provider payloads pass the same sanitizer before cache/storage; remote URLs are allowlisted and credential-free. +- Code examples use synthetic invalid/reserved canaries; no real token copied into a fixture to test detection. + +### 11.3 Facts, memories, entities, skills, and automation + +- Keep write-time secret rejection as defense in depth, but feed it the shared detector engine/profile. +- Legacy secret-like facts become immediately non-hydratable/quarantined; curation receives safe class/ID/reason only, never `truncated_content`. +- Entity extraction, embeddings, trust/dedupe/conflict logic, digests, memory injection, and skill writing never receive candidate plaintext. +- LLM/automation “do not include secrets” prompts are not controls; sanitizer and typed output validation are mandatory after model output. +- Managed-skill support files, candidates, run artifacts, and materialization packages scan before autonomy decision and again before autonomous materialization/recovery. A failed or incomplete scan automatically rejects/quarantines the candidate; it never creates a human approval queue or bypass. +- Fact tags, entity names/aliases, source descriptors, metadata/extensions, feedback, and deletion/supersession notes are content-bearing; all use eligible wrappers before persistence or projection. Legacy V11 inserts and their vectors are quarantined/imported/rebuilt, never trusted in place. + +### 11.4 Hooks, hints, policy, coordination, and analytics + +- Hook hot path uses the compiled runtime safety floor under its latency budget; timeout emits no content/hint and spools only an encrypted or non-content blocked receipt. +- Hint candidates/context/payload, nearby-agent summaries, work claims, and research labels require `PromptEligibleText`/`CatalogSafeText`. +- Policy/replay input bundles reference sanitization receipts and cannot request unsanitized content. +- Analytics store event/use-case/safe dimensions/counts only. Tool arguments, outputs, prompts, query literals, error bodies, candidate values, and secret fingerprints are prohibited. +- Hook analytics schemas have one payload-free command/use-case identity field. Differential tests prove the former two-field full-command duplication cannot be serialized through either live or compatibility analytics. + +### 11.5 API, MCP, CLI, dashboard, SDK, and browser + +- Application use cases return typed redacted/denied/unknown states; transports cannot bypass classification. +- Errors and retry directives name safe rule/state/action only. +- Cursors, anchors, URLs, deep links, SSE IDs, ETags, and operation receipts contain opaque IDs/digests of sanitized contracts, never query/candidate content. +- Dashboard never places payloads/query text in URL/history/local storage and never shows secret candidate previews. +- SDK `Debug`/`Display`, generated examples, OpenAPI examples, explorer history, source maps, and exception/log hooks pass secret canaries. +- Bounded/truncated MCP/CLI/HTTP failure reasons are constructed from safe reason enums plus `LogSafeText`; adapters cannot attach the rejected request, raw error, command, query, or payload excerpt. +- Dashboard/API startup refuses arbitrary unauthenticated host exposure. Every raw-content and metadata view is authorized and sanitizer-eligible before it reaches JSON, SSE, DOM, renderer workers, browser cache, or export. + +### 11.6 Fixtures, evaluation, exports, and release artifacts + +- A production DB/store/transcript/cache/export is never copied directly into a fixture. +- Fixture promotion selects minimum structure, sanitizes, replaces all identity/content with synthetic values, scans every generated derivative, and records a zero-findings receipt. +- Private qrels/eval prompts remain protected local data; committed evals are synthetic/minimal redacted. +- Export/share/support-bundle jobs rescan output bytes/archives before publication and include privacy manifest/coverage. +- CI scans staged diff, introduced history, archives, snapshots, generated API/SDK/docs/frontend/source maps, binaries/packages where supported, and release bundles. + +## 12. Retroactive whole-profile audit + +Create a read-only-first privacy auditor. It uses store APIs/manifests, not ad hoc SQL or raw renderer output. + +### 12.1 Inventory + +Enumerate with stable IDs and coverage: + +- Catalog, activity, project, graph generations, blobs, quarantine. +- Session/LCM/message/tool/reasoning/goal/workflow content and metadata. +- Search/FTS/representation/summary/facet/rank/cache projections. +- Facts/entities/memories/skills/automation candidates/decisions/effects, imported legacy proposal evidence, annotations, and saved content. +- Hooks/analytics/logs/error/crash/support/export/response caches. +- WAL/SHM/temp/spool/dead-letter files, backups, recovery sets, V1 stores. +- Repository fixtures/snapshots/docs/generated packages/release assets when scanning a checkout/release. + +The scanner executes inside each privacy domain and emits only safe findings/counts. A locked/unopenable/corrupt source is unknown coverage, not clean. + +### 12.2 Immediate containment + +When a high-confidence/confirmed finding appears: + +1. Mark the owning entity/store generation unsafe at a catalog-safe level. +2. Block hydration/search/export/share/hint/automation use of the entity and all derived descendants. +3. Show redacted/quarantined coverage and rotation guidance. +4. Do not print or copy the candidate while asking for remediation. + +### 12.3 Rotation and remediation + +The operator workflow is: + +1. Rotate/revoke at the credential provider outside TraceDecay; TraceDecay may link safe documentation but performs no validity/revocation network call by default. +2. Preview the full descendant graph: canonical rows, FTS, representations, summaries, facts/entities, caches, exports, backups, references, and consumers. +3. Create sanitized replacement observations/entities or tombstones. +4. Build new FTS/vector/summary/graph/project database generations from sanitized authorities. +5. Atomically swap after secret-canary/manifest/parity verification. +6. Invalidate response/export/browser caches and revoke shared bundles. +7. Checkpoint/retire old SQLite WAL/SHM/temp/database generations under a lifecycle lease. +8. Cryptographically erase quarantine keys/blobs and delete retired artifacts after recovery policy. +9. Rescan every new generation and eligible backup; retain safe remediation receipt. + +SQLite row deletion is not proof that bytes disappeared from pages, WAL, temp files, backups, or SSD media. Derived databases are rebuilt into new sanitized generations; protected raw uses cryptographic deletion. Physical-storage limitations are documented honestly. + +### 12.4 Restore gate + +Every backup/V1 rollback restore lands in an isolated non-serving staging profile: + +- verify manifest/signature/integrity. +- apply current privacy migration and scan. +- rebuild derived projections. +- require zero unexplained/unknown forbidden-sink findings. +- issue a promotion receipt before serving. + +No “emergency restore” may bypass this gate and silently reindex secrets. + +For #425/V2 split-store consolidation, the selected and legacy families remain separate privacy authorities until reconciliation proves otherwise. The workflow creates two independent encrypted/restricted backup manifests, scans both plus WAL/SHM/temp/ledger/staging/table-report/collision/remapped-edge descendants, and records unknown/unsupported coverage without copying candidate values into the plan or doctor output. A clean result for one family cannot authorize the other. Deterministic confirmation binds both source manifests, privacy policy/detector versions, table dispositions, edge-remap digest, backups, and intended marker/registry change; any drift invalidates confirmation. Marker/registry publication is forbidden until both backup restore probes and the fully rebuilt candidate pass current sanitizer/canary/parity verification. + +## 13. False positives, adjudication, and rule evolution + +Finding states: + +- `unreviewed`, `high_confidence`, `confirmed`, `false_positive`, `revoked_rotated`, `contained`, `sanitized`, `purged`, `verification_failed`, `unknown`. + +Adjudication record contains detector/rule version, keyed fingerprint, field/source context class, safe reason code, owner, created/expires time, reviewer, and policy scope. It contains no candidate or surrounding source. + +Rules: + +- Default expiry forces re-evaluation after detector/source changes. +- Allowlists are exact keyed-fingerprint/context decisions or narrowly anchored synthetic fixture classes. +- Regex/string allowlists containing a candidate secret are prohibited. +- Broad path/project/provider exclusions cannot bypass the mandatory safety floor. +- Rule changes run read-only shadow scans and measure new/removed findings before activation. +- Historical observations retain the old receipt; current projection uses the new rule version after controlled rescan/rebuild. Rescans issue superseding `SanitizationReceiptV1` rows that reference the superseded receipt ID; sinks honor the newest non-revoked receipt. The durable home for all receipts is the per-shard `sanitization_receipts` table owned by plan 02 (minted by plan 03, validated by plan 04's sink firewall), including supersession, expiry, and revocation columns. +- False-positive review UI uses synthetic/structural metadata. Viewing plaintext requires separate quarantine authorization and is not required to mark common safe examples. + +Durable detector-registry state (owning shard: profile catalog; contains no secret content): + +- `detector_rules(detector_id, rule_version)` PK — enable state, activation source (bundled/config/plugin), complexity-policy verdict, corpus-eval result digest, created/retired timestamps; index on enable state. Retention: retired rows kept for the receipt-audit horizon. +- `adjudication_records(adjudication_id BLOB PRIMARY KEY, privacy_domain_id BLOB NOT NULL, key_epoch INTEGER NOT NULL, fingerprint_hmac BLOB NOT NULL, detector_id TEXT NOT NULL, rule_version INTEGER NOT NULL, field_context_code INTEGER NOT NULL, source_context_code INTEGER NOT NULL, owner_scope_digest BLOB NOT NULL, policy_scope_digest BLOB NOT NULL, state TEXT NOT NULL, safe_reason_code TEXT NOT NULL, reviewer_id BLOB NOT NULL, created_at INTEGER NOT NULL, expires_at INTEGER NOT NULL)` — UNIQUE `(privacy_domain_id, key_epoch, fingerprint_hmac, detector_id, rule_version, field_context_code, source_context_code, owner_scope_digest, policy_scope_digest)` and indexes on expiry/state. One adjudication can authorize only the exact context/owner/policy tuple; key rotation or any context/rule change requires a new row. The opaque ID is the only ordinary-surface locator. + +Terminology: capture-side quarantine "skeletons" (plan 03's non-content provenance records) and this plan's section 10 protected quarantine (encrypted forensic payloads) are distinct stores with distinct lifecycles; plans must qualify which one they mean. + +## 14.

Program objective + +The rewrite succeeds only if TraceDecay stops behaving like a collection of adjacent products that happen to share a binary. V2 must reconcile capture, LCM, sessions, code intelligence, Git, memory, analytics, automations, tasks/plans/executors, hints, tools, API, and dashboard into one system with: + +- one authoritative owner for every concept and side effect; +- one immutable evidence path from every source into canonical observations; +- one identity and scope language across profile, repository, project, checkout, worktree, ref, provider, session, agent, and historical snapshot; +- one query/search/graph algebra and one result/coverage contract; +- one versioned policy and replay substrate; +- one generated capability catalog; +- one transport-neutral application command/query layer; +- thin CLI, MCP, HTTP, SDK, hook, and UI adapters; +- bounded, versioned extension points rather than copies or special cases; +- explicit scale, concurrency, privacy, reliability, and complexity budgets; +- a mandatory retirement path for every V1 implementation and temporary adapter. + +The target is not merely fewer files. It is less semantic entropy: fewer competing meanings, fewer hidden defaults, fewer duplicated state machines, fewer untyped strings, fewer paths around policy, and fewer ways for two clients to receive different answers to the same question. + +## 2. Evidence that convergence is required + +### 2.1 Live planning probe + +A TraceDecay context lookup against the planning worktree failed with an identity-cutover conflict: the same checkout resolved to both a selected store and a legacy store, each healthy and each containing materially different graph, fact, session, message, LCM, branch, automation, and payload counts. Retrying with an explicit project ID still re-entered the path resolver and returned the same conflict. + +This is the architecture problem in miniature: + +1. More than one store can appear authoritative for one logical identity. +2. Resolution and tool execution do not share one decisive scope result. +3. An explicit identifier is not always sufficient to bypass implicit path/CWD resolution. +4. Health is reported per shard, but the user needs a reconciliation decision for the logical system. +5. The safe behavior—preserve both and demand consolidation—is correct, but the recovery is not yet a first-class application workflow with a typed plan, preview, receipt, and postcondition. + +The final 0.0.47 refusal quantified the fragmentation. Selected `proj_ceaa713e40fef2b2` was healthy with 38,510 nodes, 987 files, 17 facts, 2,003 sessions, 432,790 messages, 419,887 LCM rows, 14 branches, `automation_files=0`, five payload files, and three response files. Legacy `proj_b4a8bbe4953823c4` was also healthy with 36,596 nodes, 989 files, 129 facts, 4,129 sessions, 603,866 messages, 592,594 LCM rows, 197 branches, 3,470 automation files, 1,839 payload files, and four response files. The missing automation lane in selected and large legacy-only lane are coverage, not evidence that either shard is globally current. + +Merged PR #425 (`de3d05dc`, final head `d3bb28b5`) is accepted V1 behavior: offline plan/apply, canonical platform paths, frozen SQLite families, final path-plus-file/inode holder refusal, reservations, dual backups, deterministic confirmation, restartable ledger/staging, explicit table dispositions/collisions, remapped LCM edges, exhaustive verification, marker/registry cutover, and doctor recovery. V2 absorbs and generalizes those invariants behind operation-specific plan/start/recover use cases; it does not keep a second consolidation authority or generic preview/apply framework. + +V2 must retain the safe refusal while making ambiguity inspectable and repairable through the same canonical identity, command, status, and receipt contracts used by CLI, MCP, API, SDKs, and dashboard. + +### 2.2 Fragmentation inventory + +The Phase 0 inventory generator must produce this table from source, schemas, routes, catalogs, configs, and store manifests.

+- `tables.json`: table/index/trigger/FTS owner, reader/writer call sites, canonical target; +- `public-surfaces.json`: CLI, MCP, HTTP, SSE, SDK, dashboard, skill, hook, installer, config, and file-format surfaces; +- `semantic-implementations.json`: ID derivation, scope resolution, redaction, search/ranking, hinting, status, error mapping, config resolution, retry, and rendering implementations; +- `dependency-graph.json`: crate/module dependency edges, cycles, forbidden imports, SQL/file-system/network use; +- `adapter-ledger.json`: every anti-corruption adapter with owner, creation PR, traffic, parity gate, rollback dependency, and deletion PR; +- `convergence-scorecard.json`: metrics in Section 13 with baseline and target; +- `inventory.md`: safe human summary with no store content or secret candidates. + +Plan 12's PR 3R compatibility-inventory generator is the single inventory generator; the artifacts above are generated views of that same run, and this plan consumes them — it does not build a second generator. Per-entity/store dispositions use plan 12 §14.1's five-value vocabulary (`retained | skipped | quarantined | redacted | deleted`); route/migration status uses PR 3R's six-value status axis (`v1_only` … `retired`). This authority relation is stated identically in plan 12 §17 PR 3R. + +The inventory records symbols and schema names, not private content. It uses supported readers and manifests; it does not crawl raw databases as an implementation shortcut. + +## 3. Governing architecture rules + +1. **One meaning, one owner.** A concept has one canonical type and one crate responsible for its invariants. +2. **One effect, one route.** A side effect enters through one application command; adapters cannot reimplement it. +3. **Evidence first.** Sources produce immutable observations before mutable projections or policy decisions. +4. **Projection, not duplication.** Read models may repeat derived fields for performance but never become competing authority; every row carries source/projection versions and watermarks. +5. **Explicit scope.** CWD is one input to resolution, never invisible authority after an explicit selector is supplied. +6. **Typed boundaries.** IDs, safe text, cursors, scopes, errors, status, commands, and query results cross crates as domain/application types, not unvalidated strings or JSON blobs. +7. **Thin transports.** CLI, MCP, HTTP, SSE, SDK, hook, and UI bind and render application behavior. +8. **Generated parity.** Repeated public schemas and capability metadata are generated from one contract IR. +9. **Extensions use SPIs.** New providers, detectors, projectors, operators, policies, and UI contributions register through bounded contracts with budgets and provenance. +10. **Local-first scale.** One binary and embedded stores are the first deployment; contracts permit isolated workers or remote/federated backends without distributing semantics. +11. **No permanent bridge.** Every compatibility adapter has a deletion gate when created. +12. **Safe failure.** Ambiguity, partial coverage, stale generations, privacy uncertainty, budget exhaustion, and version mismatch are visible typed states, not fallback triggers. + +## 4. Target canonical planes + +### 4.1 Ingestion and evidence plane + +`tracedecay-capture` owns source discovery, framing, parser/adapter execution, sanitization invocation, source offsets/generations, and construction of `ObservationEnvelopeV1`. `tracedecay-store` owns atomic journal publication, blob/quarantine persistence, outbox records, and acknowledgements. `tracedecay-projectors` alone converts observations into read models. + +Required convergence: + +- Provider transcripts, hook events, Git snapshots, code extraction, diagnostics, workflows, LCM V1, automation, memory imports, and legacy stores all enter through an adapter registry. +- One deterministic observation-ID function lives in domain; no adapter invents another UUID namespace or canonical encoder. +- Duplicate, late, rewritten, malformed, unavailable, quarantined, and unsupported records remain explicit evidence states. +- Canonical activity is written once. Project-attributed projections contain locators and derived indexes, not duplicate message bodies. +- Every projector is idempotent, deterministic for a pinned observation range/config/version, rebuildable, and watermarked. +- Direct writes from hooks/providers/transports into session, LCM, graph, analytics, memory, or dashboard stores are prohibited by architecture tests. + +### 4.2 Identity and scope plane + +`tracedecay-domain` defines `ProfileId`, `RepositoryId`, `ProjectId`, `CheckoutId`, `WorktreeId`, `RefId`, `CodeSnapshotId`, `GraphGenerationId`, `SourceInstanceId`, `ProviderId`, `ActorId`, `AgentId`, `SessionId`, `ThreadId`, `TurnId`, `MessageId`, `ObservationId`, `EntityId`, `RelationId`, `PolicyBundleId`, `CapabilityId`, and `RetrievalAnchorId`. `tracedecay-store` persists allocation and alias history. `tracedecay-application` resolves user selectors. + +Required convergence: + +- One `ScopeSelectorV2` serves CLI, MCP, API, SDKs, dashboard, hooks, jobs, and saved views. +- Resolution accepts stable IDs plus names, paths, remotes, branches, worktrees, PRs, collections, agents, and sessions as evidence-backed aliases. +- Explicit IDs bypass implicit CWD identity selection after access validation. Explicit paths resolve exactly or return candidates; they never collapse to the current project. +- A resolution result pins canonical IDs, candidate evidence, snapshot/ref generation, store routes, access decision, freshness, and ambiguity state. +- Resolution happens once per request. Downstream query, policy, and transport code receives `ScopeResolutionV2`, never repeats path/registry discovery. +- Identity reconciliation is an application workflow: preview candidates, compare coverage, choose merge/link/keep-separate, run resumably, emit receipt, verify postconditions, and preserve rollback sources. + +### 4.3 Storage and projection plane + +Physical federation remains explicit: + +- profile `catalog.db`: identity allocations, content-free keyed alias-routing projections, store registry, schema/catalog versions, entity/anchor routes, migration receipts; canonical alias values/history do not live here; +- profile `activity.db`: observations and canonical provider/agent/session/Turn/message/workflow/goal activity plus cross-project/profile knowledge and automation; +- repository/privacy-domain `project.db`: code/Git/delivery evidence and explicitly project-scoped projections; +- immutable graph generations: packed snapshot-scoped graph data; +- privacy-domain content-addressed blobs: sanitized eligible payloads plus separate protected quarantine when explicitly enabled. + +There is one logical system, not one giant SQLite file. `tracedecay-query` federates shards through declared capabilities and watermarks; transactions remain local. Cross-shard commands use journal/outbox/saga semantics and report incomplete compensation instead of pretending to be atomic. + +Every projection declares: + +- stable projection ID and owner crate/module; +- input observation/event kinds; +- schema and algorithm version; +- output store/shard class; +- watermark and lag contract; +- rebuild/checkpoint/rollback strategy; +- privacy eligibility and retention behavior; +- query operators and capability IDs it serves; +- parity corpus and performance budget. + +### 4.4 Query, search, and graph plane + +`tracedecay-domain` owns the one canonical `TraceQueryV1` AST/value/schema contract. `tracedecay-query` owns parsing, validation, canonicalization, planning, cost/budget enforcement, shard pruning, distributed cursors, graph/time/as-of operators, lexical/hybrid retrieval, ranking, diversity, explanation, and coverage reporting. + +Required convergence: + +- Session, LCM, memory, code, diagnostics, Git, agent, automation, facts, skills, and analytics queries compile from the same typed AST or call a specialized facade that compiles to it. +- Text search uses one versioned pipeline with exact/phrase/lexical foundations and optional measured fuzzy/entity/graph/dense/learned-sparse/rerank channels. +- Code graph, Git graph, thread graph, agent graph, Turn graph, timeline graph, knowledge graph, and automation graph share entity/relation/time/provenance primitives while retaining domain-specific operators. +- A query response always returns rows/nodes/edges plus pinned scope, coverage, freshness, watermarks, truncation, cost, planner/ranker versions, explanation, and stable retrieval anchors. +- No UI endpoint, MCP tool, or CLI command embeds SQL, FTS syntax, graph traversal, ranking, pagination, or store routing. +- Query caches key on normalized AST, resolved scope, access decision, snapshot/watermarks, representation/ranker versions, and privacy policy digest. + +### 4.5 Policy and replay plane + +`tracedecay-policy` owns deterministic evaluators for hints, retrieval routing, correlation, diagnostics, curation, memory, scheduler, automation, and nearby-agent coordination. It consumes immutable inputs and returns decisions/proposed effects. `tracedecay-application` revalidates effects; its curation worker autonomously applies every eligible owned fact/memory/managed-skill/profile-curation effect, monitors outcomes, and automatically revises/recovers. No item approval/apply command exists. + +Required convergence: + +- A `PolicyBundle` pins evaluator versions, configuration, catalog, index/snapshot watermarks, memory/skill versions, seed, time source, and budgets. +- Evaluation cannot write stores, call transports, read ambient CWD, or silently fetch live state. +- Exact replay uses matching artifacts; recorded replay returns stored decisions; best-effort replay declares every substitution. +- Labs and offline evaluation use the same evaluator path as live operation but an effect sink that cannot mutate live state or contaminate analytics. +- Hint/retrieval/coordination analytics distinguish eligible, emitted, suppressed, acted-on, useful, false-positive, repeated, ignored, and outcome-unknown states. +- Policy code cannot define capability names, scope rules, redaction rules, query ranking, or output rendering independently. + +### 4.6 Capability catalog + +`tracedecay-tool-catalog` is the single registry for user/agent-visible capabilities. Each `CapabilityDefinition` owns: + +- stable ID, semantic version, status, owner, aliases, and replacement; +- use-case command/query type and result/error schemas; +- allowed scopes, access requirements, privacy class, side-effect class, idempotency, retry policy, and budgets; +- CLI/MCP/HTTP/SDK/dashboard/hook/skill bindings; +- availability requirements and degraded/partial states; +- human/agent discovery phrases and examples; +- telemetry event IDs and conformance fixtures. + +Catalog generation produces CLI metadata, MCP schemas, OpenAPI/JSON Schema references, SDK method manifests, dashboard action metadata, skill/hint discovery, docs, and drift tests. It does not generate business behavior; every binding resolves to one application use case. + +### 4.7 Application command/query layer + +`tracedecay-application` owns orchestration and is the only layer allowed to combine repositories, query services, policy evaluators, permissions, locks/leases, idempotency records, jobs, and audit effects into a public use case. + +Each use case has: + +- `Command` or `Query` input with `RequestContext`, explicit `ScopeSelectorV2`, access subject, idempotency key where applicable, deadline/budget, and expected version; +- one handler with injected ports; +- typed result, warnings, coverage, status deltas, audit receipt, and stable anchors; +- typed error variants mapped by generated transport tables; +- transaction/saga boundaries and retry semantics; +- conformance cases reusable by every transport; +- a declared capability ID. + +Root composition wires implementations. Root may own bootstrap/process/service lifecycle and V1 anti-corruption adapters; it must not become a second application layer. + +### 4.8 Thin transports, SDKs, and UI + +Transport responsibilities are limited to authentication/session establishment, protocol handshake, input binding, deadline/cancellation propagation, streaming/framing, safe rendering, and transport-specific error/status mapping. + +- CLI adds terminal formatting, exit codes, stdin/files, and shell completion. +- MCP adds JSON-RPC lifecycle, tool/resource binding, Markdown/JSON rendering, and protocol/catalog handshake. +- HTTP/SSE adds auth, request/response framing, cache headers, conditional requests, streaming, and OpenAPI. +- Rust/TypeScript/Python SDKs add idiomatic types, pagination/stream helpers, retry policy, cancellation, and debug-safe rendering. +- Hooks bind host events to the bounded spool/evaluation route and host response envelope. +- Dashboard uses only the generated TypeScript client plus UI-local view state; it never calls a hidden SQL or legacy endpoint. + +Semantic conformance executes the same fixture through direct application invocation, CLI, MCP, HTTP, and SDK clients and compares normalized results, errors, warnings, coverage, anchors, and effects. + +### 4.9 Security/redaction as the model convergence case + +Redaction demonstrates why shared utilities alone are insufficient. Current behavior includes an optional LCM sanitizer, memory-specific secret rejection, Git-remote output omission, provider-native redaction markers, and tool-event content decisions. These paths answer different questions and permit gaps between input, storage, indexing, prompting, output, fixtures, and exports. + +Plan 18 replaces them with: + +1. One mandatory, versioned, parse-before-scan sanitizer before any TraceDecay persistence or agent exposure. +2. Domain taint types (`Unclassified`, `Classified`, `Sanitized`, and sink-specific eligible text) that make bypasses difficult to compile. +3. One detector registry and privacy-policy precedence model. +4. Sanitization receipts, coverage, quarantine, rescan, descendant invalidation, and secure-retirement workflows. +5. Sink-specific eligibility derived from the same sanitized result rather than independent regex calls. +6. Existing redactors/detectors retained only as fixtures/reference adapters until the canonical engine proves parity and stronger protection. + +The same convergence pattern applies to identity, search, policy, config, status, and errors: preserve useful cases, establish one typed owner, adapt temporarily, prove parity, cut over, and delete the duplicate. + +## 5.

Shared code moves to the crate that owns its invariant. A new crate requires: + +- at least two real consumers; +- a coherent domain or deployment boundary; +- a dependency direction that reduces, not hides, cycles; +- public contract and non-goals; +- independent tests/benchmarks only when it has independent behavior; +- an ADR and deletion/migration plan for code it replaces. + +### 6.2 Compile-time allowed edges + +```mermaid +flowchart TD + D["tracedecay-domain"] + S["tracedecay-store"] --> D + C["tracedecay-capture"] --> D + J["tracedecay-projectors"] --> D + CI["tracedecay-code-index"] --> D + Q["tracedecay-query"] --> D + P["tracedecay-policy"] --> D + T["tracedecay-tool-catalog"] --> D + H["tracedecay-hooks"] --> D + A["tracedecay-application"] --> D + A --> S + A --> C + A --> J + A --> Q + A --> P + A --> T + H --> A + PR["tracedecay-presentation"] --> A + PR --> D + API["tracedecay-api"] --> A + API --> D + API --> T + CONTRACT["generated public contracts + ApiProblem"] + API --> CONTRACT + CLIENT["tracedecay-client"] --> CONTRACT + R["root composition and adapters"] --> A + R --> API + R --> S + R --> C + R --> J + R --> CI + R --> Q + R --> P + R --> H + R --> T + R --> PR + TS["generated TypeScript client"] --> CONTRACT + PY["generated Python client"] --> CONTRACT + UI["dashboard"] --> TS +``` + +These arrows are compile-time import/generation edges, not network calls. `generated public contracts + ApiProblem` is the plan-17 contract-IR output materialized into each client package; it is not a server facade or a new business crate. The Rust `tracedecay-client` may import only those generated request/response/event/problem definitions and its small client-owned transport/pagination/stream runtime. It has no Cargo dependency on `tracedecay-domain`, `tracedecay-store`, `tracedecay-application`, or the server implementation in `tracedecay-api`. The TypeScript and Python clients have the equivalent package boundary. + +To preserve testability, repository and executor traits are owned by the consumer: capture owns `ObservationSink`, query owns read capabilities, projectors own projection sinks, and application owns orchestration ports. Concrete cross-crate adapters live in application/root composition, not in the lower-level crates. + +### 6.3 Runtime transport flow + +```mermaid +flowchart LR + RC["Rust/TypeScript/Python client"] -->|"authenticated UDS or loopback HTTP/SSE"| API["tracedecay-api adapter"] + UI["dashboard via TypeScript client"] -->|"authenticated HTTP/SSE"| API + API -->|"generated request + caller context"| A["tracedecay-application"] + A -->|"typed response/problem/event"| API + API -->|"wire envelope"| RC + API -->|"wire envelope"| UI + ROOT["root CLI/MCP adapters"] -->|"in-process application port; no loopback HTTP"| A +``` + +Runtime calls do not create compile dependencies in the opposite direction: application and API never import an SDK, and clients never reach store/domain/application APIs in-process. The optional Rust in-process conformance transport implements the generated client transport trait in test/root composition and still targets the application contract without adding production client-to-server-crate dependencies. + +### 6.4 Publication consequences + +Plan 12 owns release execution, but its publication manifest must be a topological projection of this DAG: `tracedecay-domain`; then the domain-only implementation crates (`tracedecay-store`, `tracedecay-capture`, `tracedecay-projectors`, `tracedecay-code-index`, `tracedecay-query`, `tracedecay-policy`, and `tracedecay-tool-catalog`); then `tracedecay-application`; then `tracedecay-hooks`, `tracedecay-presentation`, and `tracedecay-api`; then the official `tracedecay-client` from the same frozen generated-contract digest; and finally the root package. Peers in a wave may publish concurrently only when `cargo metadata` and generated-contract edges prove they are independent. Every artifact must become registry-readable with the expected checksum before a dependent wave starts. + +### 6.5 Forbidden edges and capabilities + +- Domain imports no TraceDecay crate and performs no filesystem, database, network, process, clock, random, or ambient-environment I/O. +- Store contains no provider parser, ranking, policy, transport, dashboard, or remediation decisions. +- Capture contains no SQL/store implementation, projection, query, ranking, policy, transport, or dashboard code. +- Projectors contain no transport, UI, provider discovery, live network, policy decision, or ad hoc ID derivation. +- Query contains no writes to canonical stores, transport rendering, provider discovery, policy decisions, or ambient CWD resolution. +- Policy contains no store/network/filesystem/clock/random capability except injected deterministic inputs and bounded pure extension runtimes. +- Hooks contain no broad graph scan, migration, indexing, automation, remote request, or direct store/query implementation. +- Tool catalog contains metadata/validation/generation, never use-case execution. +- API contains no business mutation, SQL, ranking, policy, provider parsing, or V1 fallback. +- Client packages contain no domain/store/application/server imports, SQL, scope resolution, routing, retry invention, scheduler logic, or in-process business calls; they serialize generated contracts and invoke the service at runtime. +- Root contains no new business rules; new behavior lands in its owning crate/application first. +- Dashboard contains no private endpoint client, SQL-shaped request, capability-name literal registry, or independent error/status semantics. + +CI validates these constraints through `cargo metadata`, import/source scans, feature matrices, compile-fail tests, and a checked dependency policy file. + +## 7. Extension and plugin SPIs + +### 7.1 Principle + +Extensibility means adding a bounded implementation without copying a pipeline or editing every transport. It does not mean arbitrary code can mutate stores or introspect private content. + +Every SPI has: + +- stable namespaced ID and version range; +- manifest-declared inputs, outputs, source/effect/privacy classes, capabilities, resource budgets, and determinism; +- typed host calls and no access beyond declared capabilities; +- schema validation and conformance fixtures; +- executable/content digest and provenance; +- timeout, memory, output-size, cancellation, and failure-isolation rules; +- availability/status reporting; +- safe upgrade, disable, rollback, and state-migration behavior; +- compatibility policy that rejects unsupported major versions explicitly. + +### 7.2 Supported SPIs + +| SPI | Owner | Extension can do | Extension cannot do | +|---|---|---|---| +| Source adapter/parser | Capture | Discover declared source, frame records, parse into observation drafts | Allocate canonical IDs independently, write stores, weaken privacy, make policy decisions | +| Code extractor/grammar | Code index crate (plan 25), fed by capture-sanitized content | Produce typed syntax/symbol/edge observations for a snapshot | Query live project stores or publish graph generations directly | +| Secret detector | Capture privacy engine | Return protected spans/classes/confidence under sandbox and budgets | Emit candidate content, use network/filesystem, bypass mandatory built-ins | +| Projector | Projectors | Consume declared observation kinds and emit typed projection mutations | Read ambient state, call transports, mutate unrelated projections | +| Query operator | Query | Add a typed bounded operator with cost/coverage/explain implementation | Bypass scope/access/budget, return unanchored evidence, mutate state | +| Retrieval representation/ranker | Query | Build/version representation and score bounded candidates | Receive unauthorized content, silently become default, skip labeled evaluation | +| Policy evaluator | Policy | Evaluate pinned typed inputs and return decisions/proposed effects | Perform I/O/effects, invent capability IDs, hide substitutions | +| Output renderer | Transport-owned | Render typed safe view models | Fetch data, apply business rules, reveal protected fields | +| Dashboard contribution | Frontend registry | Register route/panel/lens for declared capability/view model | Call private endpoints, inject global CSS/state, bypass access/coverage semantics | +| Automation/skill provider | Application/policy/catalog | Register candidate/validation/autonomous-execution/monitoring/recovery capability with audit lifecycle | Execute outside configured authority, modify own evidence, access secrets, or create a per-item human gate | + +### 7.3 Runtime tiers + +1. **Built-in Rust:** first-party, compiled, full conformance, least runtime overhead. +2. **WASM component:** preferred untrusted/third-party pure transform/evaluator; capability-free by default with bounded host calls. +3. **Isolated subprocess:** only for extractors/tools needing native runtimes; authenticated framed protocol, sandbox profile, restricted environment/filesystem/network, hard budgets. +4. **Remote extension:** deferred; requires explicit user configuration, authenticated protocol, privacy-domain egress policy, offline/degraded semantics, and threat-model ADR. + +No unstable Rust dynamic-library ABI is a public plugin contract. WIT/JSON Schema/protobuf-like wire contracts are generated from the same versioned SPI IR where applicable. The first release may keep SPIs internal until two implementations and conformance suites prove the boundary; internal status must not be documented as stable public API. + +### 7.4 Extension registry and dependency rule + +The capability catalog references extensions by ID/digest and exposes availability. Owning crates host the registries. Do not add a general extension-runtime crate until at least two owners share identical sandbox/protocol lifecycle behavior; if that threshold is reached, extract a narrow `tracedecay-extension-host` crate that depends only on domain wire contracts and contains no domain-specific policy. + +## 8. Naming, schema, version, configuration, status, and error governance + +### 8.1 Ubiquitous language + +Maintain `docs/architecture/glossary.md` and machine-readable domain registry. Reserved terms have one meaning: + +- **observation:** immutable source record plus provenance; +- **event:** canonical domain occurrence projected from evidence; +- **entity:** stable logical thing with aliases/occurrences; +- **relation assertion:** time-bound, sourced claim connecting entities; +- **projection:** rebuildable derived read model; +- **session:** provider/user interaction container; +- **Turn:** one agent execution unit, distinct from a message; +- **agent:** actor/runtime instance, distinct from provider/model/session; +- **project:** logical scoped workspace, distinct from repository/checkout/worktree; +- **scope:** explicit query/effect boundary; +- **snapshot/generation:** immutable pinned code/graph/index state; +- **capability:** discoverable public use case, distinct from transport binding; +- **policy decision:** deterministic evaluation output, distinct from applied effect; +- **retrieval anchor:** durable locator to retained evidence, distinct from response handle. + +The registry forbids overloaded aliases in public schemas without a migration annotation. Rust types, JSON fields, CLI flags, MCP properties, OpenAPI, SDKs, UI labels, telemetry, and docs derive from or validate against the same vocabulary. + +### 8.2 Schema governance + +- Every persisted/event/API/SPI schema has a namespaced ID, semantic version, owner, compatibility class, privacy classification, and migration function or explicit non-migratable status. +- Additive optional changes are minor only when defaults do not change meaning. New required fields, changed units/meaning, or removed variants are major. +- Persisted observations retain original bytes only when eligible; canonical decoded representation records parser/schema version. +- Projection schema changes use new generation/backfill and atomic publication, not in-place semantic mutation without a receipt. +- Unknown enum variants/fields survive capture where the source format permits, but public handlers fail or degrade explicitly according to the schema contract. +- Golden schema snapshots, upgrade/downgrade fixtures, and API/SPI compatibility checks run in CI. + +### 8.3 Configuration governance + +One typed resolver evaluates built-in defaults, profile, project/privacy-domain, provider/source, environment, CLI/request override, and policy floor according to field-specific precedence. Each `EffectiveConfigValue` carries value, source, version, validation, sensitivity, changeability, and restart/rebuild impact. + +- Safety floors cannot be weakened downstream. +- Unknown keys and obsolete names are errors with current replacement/remediation. +- Secret values are references to an external protected mechanism, never status/debug content. +- Query/policy/replay pin effective-config digests. +- Dashboard settings, CLI config, doctor, hooks, daemon, automation, and SDKs use the same read/update application commands. + +### 8.4 Status governance + +One `SystemStatusSnapshot` assembles component states without hiding disagreement: + +```text +component_id, owner, state, reason_code, observed_at, +coverage, freshness, watermark, configured_version, effective_version, +desired_version, dependencies, blocked_by, remediation_capability_id, +safe_details, retrieval_anchors +``` + +States include `Healthy`, `Degraded`, `Partial`, `Stale`, `Reconciling`, `Blocked`, `Quarantined`, `Unavailable`, and `Unknown`. “Healthy” cannot be inferred merely because a table has rows or a database opens. Conflicting identity stores, missing shards, unscanned privacy data, unsupported adapters, skipped sources, and lagging projections remain first-class components. + +### 8.5 Error governance + +Errors are layered without leaking implementation strings: + +- domain invariant errors; +- repository/storage errors; +- capture/projection/query/policy errors; +- application use-case errors; +- transport binding/rendering errors. + +Every public `TraceErrorV2` includes stable `code`, category, safe message, retryability, retry-after when applicable, capability/use-case ID, trace/request ID, safe structured details, cause class, partial-result/side-effect state, remediation capability ID, and retrieval anchors. Sensitive candidates, SQL, filesystem internals, raw provider records, tokens, and unbounded chains never enter public details. + +Generated mapping enforces CLI exit code, MCP error, HTTP status/problem detail, SDK exception, SSE terminal event, and dashboard presentation parity. Tests assert semantic identity across transports. + +## 9. Generated contracts and drift prevention + +### 9.1 Contract IR inputs + +- domain schema registry; +- capability catalog; +- application use-case registry; +- API route/event registry; +- SPI registry; +- error/status/remediation registries; +- configuration schema and vocabulary registry. + +### 9.2 Generated outputs + +- JSON Schema and OpenAPI; +- CLI command/flag/completion/reference metadata; +- MCP tool/resource/prompt schemas and discovery metadata; +- Rust/TypeScript/Python public types and method manifests; +- dashboard client, query keys, event discriminants, error/status maps, action registry; +- hook/provider binding manifests; +- managed-skill capability references and hint-discovery facts; +- docs/reference/examples with synthetic safe values; +- telemetry event/field registry; +- conformance vectors and compatibility snapshots. + +### 9.3 Drift gates + +CI regenerates into a temporary directory and fails on diff. It also fails when: + +- a public route/command/tool/action lacks a capability ID; +- two bindings claim the same public name without an explicit alias/replacement relation; +- a hand-written transport schema conflicts with generated IR; +- an error/status/config enum is missing a transport mapping; +- a dashboard action calls an unregistered route; +- SDK/API schema digests differ from the binary/catalog handshake; +- a removed capability lacks migration/replacement and cutoff metadata; +- generated fixtures/examples fail the privacy scan. + +Generated code remains mechanical. Human-written ergonomic SDK helpers and UI view models may wrap it but cannot redefine semantics. + +## 10. Concurrency, sharding, and scale + +### 10.1 Workload model + +Design and benchmark at minimum: + +- 128 simultaneous hook/agent producer lanes on one profile; +- agents split across the same worktree and parallel worktrees; +- hundreds of registered repositories/projects and many historical checkouts; +- millions of messages/tool events and large LCM summary DAGs; +- multiple code graph generations per branch/ref/worktree; +- concurrent capture, projection, query, backup, rescan, automation, and dashboard streaming; +- disk-full, locked database, corrupt tail, process crash, stale daemon, upgrade drain, and unavailable shard conditions. + +### 10.2 Writer and consistency topology + +- Per-profile and per-project writer ownership is explicit; processes do not race for implicit global SQLite writers. +- Hooks append to per-producer durable spool segments with monotonic producer sequence and bounded synchronous deadline. +- Drainers publish observations idempotently and acknowledge only after journal durability. +- Journal/outbox drives projectors, representations, analytics, policy outcomes, and notifications. +- Readers pin vector watermarks across catalog/activity/project/graph/representation generations. +- Distributed/federated responses report per-shard coverage and staleness; they never claim one atomic snapshot when one was not available. +- Backpressure propagates typed states and preserves priority/reserved capacity for safety/ack records. +- Leases have owner, fencing token, expiry, heartbeat, takeover, and diagnostic history. + +### 10.3 Shard and representation policy + +- Shard by ownership/privacy/failure domain, not by whichever module first needs a database. +- Catalog routes logical scope to stores; query planner prunes before opening shards. +- Graph and search generations are immutable and atomically published. +- Large payloads are content-addressed in their privacy domain; projections carry safe locators/digests. +- Rebalancing/moving a repository creates a resumable copy/verify/publish/retire receipt without changing logical IDs. +- Optional remote federation must implement the same repository/query capability traits, coverage semantics, privacy egress rules, and cursor model before it can be selected. + +### 10.4 Performance budgets + +Each plane publishes a benchmark manifest and current/10x/100x corpus results. At minimum gate: + +- hook append plus mandatory safety floor meets the hook plan p95 target and never bypasses privacy on timeout; +- point identity/scope resolution does not scan all registered shards; +- common scoped list/search queries prune to the minimal shard set; +- cross-project query latency reports planning, shard-open, candidate, rank, hydration, and rendering components; +- projector throughput remains above sustained ingest with bounded recovery lag; +- graph/timeline queries enforce node/edge/time/memory budgets and stream progressive results; +- dashboard renderers enforce level-of-detail and main-thread/frame budgets; +- no benchmark improvement may trade away correctness, coverage truth, privacy, or deterministic replay. + +The exact numeric SLOs remain those in owning plans and the master performance section. This document adds the requirement that every SLO identify one canonical measured path; V1/adapter paths cannot be averaged together to conceal a regression. + +## 11. Organization and complexity budgets + +### 11.1 Source layout budgets + +- Production Rust/TypeScript files target at most 400 lines; 800 lines is a hard default ceiling. +- A file above 800 lines requires a temporary architecture waiver naming split owner, reason, and deletion PR; generated files and data-only registries are exempt but must be clearly generated. +- Functions target at most 60 lines and a hard default of 100; parsers/state machines may exceed only with focused tests and a documented reason. +- Cyclomatic complexity target is <=15 per function; higher values require decomposition or an explicit tested state-machine/table representation. +- Public functions target <=6 parameters; use typed request/context structs instead of positional growth. +- Nesting deeper than four control levels is rejected unless generated or a parser with a documented grammar. +- A module directory with more than 12 peer implementation files requires subdomain grouping and a `mod.rs`/README ownership map. +- One source file owns one primary responsibility; `utils`, `helpers`, `common`, `misc`, and numbered continuation files are prohibited as destinations for new behavior. + +### 11.2 Dependency and API budgets + +- Zero dependency cycles among V2 crates. +- Domain has zero runtime dependencies on database, async runtime, web, CLI, provider SDK, or filesystem libraries. +- Public API growth is measured per PR; additions require owner, use case, compatibility class, tests, and docs. +- Each crate publishes an `ARCHITECTURE.md` with responsibility, non-goals, public ports, allowed/forbidden edges, state ownership, and extension points. +- Internal module visibility is default; public re-exports occur from deliberate crate facades. +- Feature flags represent deployment/optional heavy capabilities, not contradictory semantics. + +### 11.3 Review gates + +CI/reporting records file/function/complexity deltas, new public items, new dependencies/features, unsafe blocks, SQL locations, stringly typed IDs, duplicate detectors/resolvers/rankers, and adapter count. A budget violation blocks the slice unless the waiver is reviewed with the architecture owner and has a specific expiry. + +## 12. Strangler migration and mandatory deletion schedule + +### 12.1 Anti-corruption adapter contract + +Every V1 adapter is registered at creation: + +```text +adapter_id, bounded_context, v1_source, v2_target, owner, +created_in_pr, shadow_start_gate, cutover_gate, rollback_dependency, +traffic_counter, mismatch_counter, delete_in_pr, status, waiver_expiry +``` + +Adapters may translate types/calls/results. They may not add policy, query planning, identity derivation, projection, SQL beyond the V1 repository, or silent fallback. Each invocation emits safe adapter telemetry so unused bridges can be proven removable. + +### 12.2 Per-context strangler sequence + +1. **Inventory/freeze:** enumerate V1 surface/store/schema/config/error/status behavior and freeze fixtures. +2. **Contract:** land V2 types/ports/catalog definition with no route change. +3. **Import/shadow:** capture/import V1 evidence and execute V2 read/decision path without effects. +4. **Compare:** explain mismatches against pinned watermarks; resolve or explicitly approve intentional differences. +5. **Cut over one effect owner:** route writes/commands to V2, retain V1 read-only data for declared rollback, and record a plan 12 §9 `CutoverReceiptV1` (HMAC-signed with the profile-local catalog key per plan 12 §9). +6. **Cut over reads:** V2 becomes default; no live fallback to stale clients/protocols/names. +7. **Rollback drill:** current binary can restore declared data route without reactivating obsolete client semantics. +8. **Retire:** remove route flag, adapter, direct readers/writers, schema migration code no longer required, config/metrics/docs/tests for obsolete behavior. +9. **Delete/securely archive:** remove stores/artifacts whose plan 12 §14.1 disposition is `deleted` after retention/privacy gates; preserve signed manifests/receipts and minimal redacted fixtures. + +### 12.3 Mandatory deletion waves + +| Wave | Earliest owning phase/PR | Must be deleted when gate passes | +|---|---|---| +| D0: semantic duplicates | PR 4/8/22A contracts | Duplicate ID derivation, scope enums, capability lists, shared error/status/config constants after callers use canonical types | +| D1: store and capture writes | PR 5–10 | Direct provider/hook/session/LCM/analytics/graph writes outside capture/journal/projectors; obsolete backfill markers after receipts | +| D2: query forks | PR 11–16 | Direct SQL/FTS/graph/ranking in CLI/MCP/dashboard and duplicate session/LCM/memory/code pagination/filter paths | +| D3: policy forks | PR 23 series | V1 hint/routing/retrieval/curation/scheduler/coordination evaluators after shadow/calibration/replay gates | +| D4: application/transport forks | PR 24 series | Business mutations/remediation/store routing in CLI/MCP/HTTP/hooks; hand-maintained schemas and clients | +| D5: legacy dashboard | PR 25–32 | Old per-project shell, bespoke endpoints, duplicated filter/action state after route/deep-link/table/export/accessibility parity | +| D6: V1 live system | PR 33–37 | V1 writers, live readers, route flags, adapters, old tool names/protocols, duplicate stores eligible for retirement, obsolete tests/config/docs | + +An adapter cannot survive beyond its `delete_in_pr` merely because it is convenient. Extension requires an ADR, evidence of an unmet rollback/parity obligation, a new bounded expiry that still precedes PR 37, and scorecard visibility. The single program-wide adapter end state, stated identically here, in Section 16, in plan 12, and in the master plan: **PR 37 completes with zero live compatibility adapters; every waiver has an expiry that precedes PR 37; expired waivers block CI.** PR 37 also cannot complete with a live V1 store route or duplicated semantic owner. Enforcement is mechanical, not aspirational: the §12.1 adapter registry is the ledger of record; the §13.2 architecture lint counts call sites per `adapter_id` at HEAD and fails any PR that adds a new call site to a registered adapter (or otherwise increases its count) without a ledger amendment; and every adapter row must link its deletion PR before its wave gate closes. + +### 12.4 Reconciliation workflows before deletion + +For split identity/store/session/graph cases: + +- normalize canonical platform paths, reject unsupported/open holders, reserve every source/destination writer, freeze both SQLite families, and capture a signed inventory/watermark (HMAC with the plan 12 §9 profile-local catalog key, `key_id` recorded); +- create and restore-probe an independent immutable backup of every conflicting source before staging; one successful backup never covers another source; +- compute a deterministic confirmation over both source manifests, policy/config/catalog versions, target, table dispositions, remapped-edge digest, collisions, backups, and intended marker/registry update, then revalidate it under the same locks immediately before publication; +- compute entity/observation/projection overlap by privacy-domain-keyed source fingerprints and proven aliases; +- classify every table/index/trigger/sidecar and record as merge/rebuild/reject plus unique, duplicate, conflicting, corrupt, unavailable, secret-flagged, or unsupported; preserve remapped LCM summary/source edges explicitly; +- inspect merge/link/keep-separate effects without content disclosure; +- append/import idempotently into canonical evidence, never copy projection rows as authority; +- rebuild projections/representations; +- compare counts, hashes, coverage, retrieval anchors, and representative queries; +- checkpoint restartable ledger/staging states at every durable boundary; status/doctor emits the exact resume/recover action; +- publish marker plus registry route atomically only after exhaustive verification and emit a reconciliation receipt; +- retain old store read-only for the bounded rollback/evidence window; +- securely retire WAL/temp/cache/backups as required by plan 18. + +## 13.

Contract lock + +1. There is one configuration registry, one application resolver, one immutable history model, and one effective-snapshot format. CLI, MCP, HTTP, SDKs, hooks, daemons, dashboard, automations, and tests cannot own parallel defaults or precedence rules. +2. Every user-controllable non-secret setting is represented in the registry. It is searchable and explainable on every generated surface, editable at every legal writable layer, and never controllable only through a hidden file, environment variable, or dashboard-only toggle. +3. Built-in defaults, the non-disableable safety floor, process observations, and foreign-owned host state are visible but read-only. If a behavior is intended to be user-configurable, its registry descriptor must expose at least one supported writable layer rather than requiring an environment-only escape hatch. +4. Secret material is not configuration data. Configuration stores only opaque keyring/vault references and safe availability metadata. Values, prefixes, fingerprints, connection strings, tokens, headers, and environment expansions never appear in configuration reads, history, audit, logs, SSE, exports, diagnostics, URLs, or browser storage. +5. `ScopeSelectorV2` is the only selector used to resolve repositories, projects, checkouts, worktrees, providers, hosts, and related entities. Durable configuration ownership records `DeclaredScope`; no route, CWD, current branch, selected dashboard node, or last-used project silently supplies ownership. +6. A configuration layer can strengthen a safety invariant but cannot weaken its parent or the built-in floor. Unknown coverage, missing detectors, invalid policy, unavailable credential references, or incompatible runtime versions fail closed where safety is involved. +7. Ordinary configuration uses direct validate-and-save semantics with optimistic concurrency. The product does not force a `preview -> apply -> rollback` ceremony for routine edits. +8. Inline impact is informational and exact: hot reload, next request, new agent session, host restart, daemon restart, store reopen, rescan, reproject, reindex, migration, or unsupported. A separate destructive system operation may require explicit confirmation; saving a non-destructive setting does not. +9. Configuration history is append-only. Returning to prior non-secret values creates a new forward revision and revalidates the current schema and safety floor; history is never rewritten and an old unsafe effective state cannot be resurrected. +10. Curation is fully autonomous. Memory curation, session reflection, skill writing/evolution, fact reconciliation, and related self-improvement do not expose per-item preview, apply, reject, approval, or rollback queues. Configuration controls the global/scoped autonomy policy, schedules, budgets, quality floors, and failure behavior; the autonomous engine executes and audits items itself. +11. Replay labs are read-only. They can resolve historical versus current effective configuration and measure resulting policy behavior, but they cannot mutate settings or become an approval path for curation. +12. Generated bindings and the Settings workspace are projections of the same registry and application use cases. Hand-authored forms, CLI switches, MCP schemas, OpenAPI fields, or SDK options that introduce an unregistered setting fail CI. +13. The control plane records desired, activated, effective, and observed runtime state separately. A persisted value is not claimed effective until its consuming component acknowledges the exact configuration generation. +14. Cross-shard updates do not pretend SQLite provides distributed transactions. Revisions are staged in their owning shards and become visible together only through an atomically published activation manifest; failures before publication leave the previous generation effective. +15. V1 configuration readers are bounded migration inputs only. After cutover there is no live fallback to legacy files, dashboard state, plugin metadata, or stale daemon defaults. + +## 2. Why this control plane exists + +TraceDecay currently exposes behavior through many unrelated mechanisms: root/profile/project files, CLI flags, process environment, provider installation metadata, hook payload settings, dashboard mutations, daemon startup options, tool-specific defaults, memory and automation policy, database layout choices, and code constants. The result is hard to reason about: + +- users and agents cannot enumerate what can be configured; +- the same concept can have different names and defaults across CLI, MCP, hooks, and dashboard; +- a displayed value rarely explains its source, precedence, or consuming process; +- settings can be accepted but not active until an undocumented restart; +- changing search, privacy, capture, or indexing behavior can leave incompatible projections behind; +- configuration copied between projects loses identity and scope; +- secrets can accidentally become printable config values; +- per-provider metadata can weaken protections that were expected to be global; +- automation and curation controls can be mistaken for item approval queues; +- hand-edited files and environment overrides create drift that doctor cannot explain. + +The V2 control plane makes configuration part of the observable system. An agent or human can ask: “What controls this behavior, what is effective here, why, what changed, which components consumed it, and what must happen next?” and receive one stable answer across all surfaces. + +## 3. Goals and non-goals + +### 3.1 Goals + +- Define every setting once with stable identity, type, constraints, legal layers, merge semantics, sensitivity, documentation, deprecation, and operational impact. +- Make Brain `/settings` the complete visual control surface, not a partial dashboard subset. +- Make `tracedecay config` an agent-friendly JSON API and a human-navigable terminal tree generated from the same registry. +- Explain every effective value as a complete source chain, including ignored, shadowed, clamped, invalid, stale, and pending layers. +- Support profile, project, repository, checkout/worktree, provider/source, and host/runtime targets without stringly paths or implicit CWD behavior. +- Make configuration updates compare-and-swap, idempotent, auditable, and safely visible to many simultaneous readers and writers. +- Publish bounded SSE changes so Settings, status, hooks, agents, and daemons converge without polling races. +- Expose exact restart, rescan, reproject, reindex, migration, credential, and compatibility consequences before save and track them after save. +- Keep redactor, detector, privacy, retention, and quarantine controls fully visible while preserving a non-disableable safety floor. +- Preserve autonomous curation while making its policy, budgets, schedule, health, and outcomes observable and configurable. +- Support safe non-secret import/export, declarative fleet setup, diff, drift detection, and version migration. +- Pin configuration digests in query, policy, replay, projection, sanitization, hook, and audit receipts. + +### 3.2 Non-goals + +- No general secret manager, plaintext credential editor, secret reveal endpoint, or encrypted-secrets-in-config-file feature. +- No second scope language. Human locators are resolved through `ScopeSelectorV2` and persisted targets use canonical IDs plus `DeclaredScope`. +- No dashboard-side precedence, cross-field validation, impact inference, or restart logic. +- No generic JSON map whose meaning is known only to a consumer. +- No setting that bypasses typed application commands through direct file/database edits. +- No remote control plane in the first V2 default. The official local API can later be bound remotely only under the security model in plans 10 and 17. +- No per-item curation proposal review, manual promotion inbox, approval gate, or item rollback workflow. +- No automatic destructive migration merely because a setting changed. +- No claim of all-or-nothing cross-shard database writes; only atomic effective-generation publication after every staged revision validates. + +## 4.

Display labels are localized metadata, never identity. Renames retain aliases and an explicit migration; a key cannot be silently reused for a different type or meaning. When a key leaves the registry entirely, stored layer revisions that still contain it remain immutable history: the resolver excludes the orphaned entries from effective resolution and surfaces them as typed `orphaned_key` items in `config.status`, `config.history`, and `config.diff` with migration guidance; they are never silently dropped, reinterpreted, or revived by re-registering the same name with different semantics. Extension-owned orphans additionally follow Section 19. + +### 5.1 Module descriptor + +Each owning crate exports a static/generated manifest: + +```rust +pub enum ConfigSensitivityV1 { + CatalogSafe, + Protected, + CredentialReference, +} + +pub struct ConfigDescriptorV1 { + pub key: ConfigKey, + pub module_id: ConfigModuleId, + pub schema_id: SchemaId, + pub value_kind: ConfigValueKindV1, + pub default: ConfigValueV1, + pub allowed_layers: Vec, + pub precedence: Vec, + pub merge: ConfigMergeStrategyV1, + pub sensitivity: ConfigSensitivityV1, + pub changeability: ConfigChangeabilityV1, + pub constraints: Vec, + pub consumers: Vec, + pub impacts: Vec, + pub ui: ConfigUiMetadataV1, + pub docs: ConfigDocumentationV1, + pub introduced_in: SchemaVersion, + pub deprecated: Option, +} + +pub struct ConfigModuleManifestV1 { + pub module_id: ConfigModuleId, + pub owner_crate: NativeKindCode, + pub version: SchemaVersion, + pub descriptors: Vec, + pub cross_field_constraints: Vec, + pub migrations: Vec, +} +``` + +Rules: + +- Defaults are typed canonical values, not JSON snippets or values parsed independently by each consumer. +- Constraints are deterministic, bounded, side-effect-free programs with stable reason codes. +- A descriptor explicitly lists legal layers and a total precedence for the dimensions it accepts, subordinate to the normative Section 6.1 skeleton: the `precedence` vector orders only the step 3 dimension layers. Repository, worktree, provider, and host are not assigned an accidental global order. +- Merge strategies are closed enums. Arbitrary code callbacks cannot make effective resolution nondeterministic. +- `String` and structured text descriptors declare maximum sizes and pass plan 18 sanitization before persistence, history, rendering, or export. +- `CredentialReference` stores only an opaque reference and safe provider/status metadata. +- Every impact rule names the consuming component, trigger predicate, required operation capability, and whether the old value remains effective while work is pending. +- UI grouping, labels, examples, documentation, enum options, and accessibility descriptions are generated from the descriptor. They do not redefine semantics. + +### 5.2 Registry generation and validation + +The build generator combines all manifests into one registry artifact, `generated/config-registry-v1.json`: typed descriptors, JSON Schema fragments, and the `ConfigRegistryDigest`. The pipeline runs in exactly one direction from there: plan 08's catalog build consumes that file as an input manifest, pins `ConfigRegistryDigest` in `ToolCatalogSnapshot`, and is the sole emitter of config surface metadata — OpenAPI fragments, CLI metadata, MCP schemas, SDK types, dashboard form metadata, docs, and conformance fixtures; plan 21 renders only from those plan 08 catalog artifacts. The registry generator emits no second surface-metadata set. Registry generation is byte-identical across platforms, path syntax, time zones, locales, and map insertion order; CI runs the generator twice from a clean tree and compares digests. In program order, PR 22A lands the catalog consuming the frozen Phase-0 registry subset; PR 22C completes the registry, and every registry change regenerates the plan 08 catalog in the same commit — registry before catalog in every build. + +Generation fails when: + +- a key, alias, module ID, consumer ID, or schema ID is duplicated; +- a writable setting has no writable layer or generated mutation capability; +- a user-controllable setting is environment-only; +- a secret-bearing type is printable/exportable or lacks `CredentialReference` semantics; +- a safety-critical key permits a layer that can weaken its floor; +- precedence omits or ambiguously orders an allowed layer pair; +- a consumer is unknown or has no acknowledgement protocol; +- an impact lacks a status/operation mapping; +- a deprecated key lacks replacement, migration, and removal policy; +- dashboard, CLI, MCP, HTTP, SDK, docs, and registry key inventories differ; +- a configuration example fails the privacy scan. + +CI also inventories legacy config reads, direct environment access, root flags, provider metadata, dashboard forms, and constants. Every retained public behavior must map to a registry key or an explicitly documented non-config runtime observation. + +## 6. Scope, targets, and ownership + +Configuration needs both query scope and durable ownership. They are not interchangeable. + +```rust +pub struct ConfigTargetV1 { + pub layer_kind: ConfigLayerKindV1, + pub target: ConfigTargetRefV1, + pub declared_scope: DeclaredScope, + pub resolution_id: ScopeResolutionId, +} + +pub enum ConfigTargetRefV1 { + Profile(ProfileId), + Project(ProjectId), + Repository(EntityRef), + Worktree(EntityRef), + Provider(EntityRef), + Host(EntityRef), +} +``` + +- Reads accept `ScopeSelectorV2`, resolve it once through the application resolver, and return every eligible target plus ambiguity, stale, unavailable, quarantined, or missing coverage. +- Mutations require exactly one canonical `ConfigTargetV1` per layer patch. A multi-target request is a batch workflow, not a string wildcard. +- `declared_scope` controls canonical shard ownership exactly as plan 01 specifies. The application verifies that the target/entity evidence supports it; it never derives ownership from a route or CWD. +- Profile/provider/host settings are normally profile-owned. Project settings are project-owned. Repository/worktree settings require explicit project, cross-project, or zero-project ownership according to their canonical relation evidence; the same repository path cannot be guessed into an arbitrary project. +- Cross-project settings use the exact versioned `DeclaredScope::CrossProject` membership digest. Membership changes do not silently widen a previously saved config layer. +- A repository or worktree locator entered in UI/CLI is a sanitized `ScopeTargetV2::Locator` inside `ScopeSelectorV2`; the stored target is the resolved canonical `EntityRef`. +- `CurrentInvocation` is allowed only when the caller deliberately chooses it. `tracedecay config set` does not narrow to CWD by omission. +- The default Settings workspace reads explicit active-profile `AllAuthorized`; project routes add a visible filter without changing ownership. + +### 6.1 Layer precedence + +The resolver evaluates, for each key, only layers declared by its descriptor: + +1. typed built-in default establishes a complete value; +2. profile layer establishes the user's baseline; +3. applicable host/provider/project/repository/worktree layers merge in the descriptor's explicit order; +4. allowed request override applies only to keys marked ephemeral and never persists; +5. the safety-floor constraint clamps or rejects the result and records why; +6. cross-field constraints validate the complete snapshot; +7. runtime compatibility can hold a desired value pending rather than pretending it is effective. + +This seven-step skeleton is normative. A descriptor's `precedence` vector orders only the step 3 dimension layers it accepts (`Host`, `Provider`, `Project`, `Repository`, `Worktree`); it cannot reorder `BuiltInDefault`, `Profile`, `RequestOverride`, the safety floor, or cross-field validation, and the generator rejects a vector that lists a layer outside step 3 or leaves an allowed step 3 pair ambiguously ordered. `EnvironmentObservation` layers evaluate at the end of step 3 — after every persisted scope layer and before `RequestOverride` — and only for keys whose descriptor allows the layer; `RequestOverride` is always step 4. + +The safety floor is logically highest authority even though it validates last. A source chain distinguishes `selected`, `merged`, `shadowed`, `clamped`, `invalid`, `pending`, and `ignored_not_applicable`. Every discarded value has a stable reason. + +Environment variables become typed `EnvironmentObservation` layers only for bootstrap and automation compatibility. They are visible with process/host provenance, cannot contain secrets in returned views, and cannot be the sole supported control for user behavior. Persistent UI/CLI edits create an explicit writable override; they do not rewrite the parent process environment. + +## 7.

Activation is derived only from membership in the manifest reached by `config_activation_heads`. Abandonment is a separate immutable `ConfigRevisionAbandonmentV1` event/row with uniqueness on `revision_id`. A revision with an unexpired preparation pin or any manifest membership cannot be abandoned/collected. Rows referenced by any activation manifest, receipt, export, or replay pin are retained permanently; an unreferenced revision can be collected only after a durable abandonment row and the abandonment window. Entry values are bounded by descriptor maximum sizes and one revision stays <=1 MiB canonical encoding. Owning shard follows the target per Section 6. +- `ConfigRevisionPreparationV1`: primary key `preparation_id`; unique `(activation_id, target)` and `(activation_id, revision_id)`; owner-shard transaction checks revision digest/no abandonment, materializes the target-specific effective snapshot, and pins both until expiry under the lifecycle lease epoch. It is immutable. Publication consumes its exact receipt. Release is a separate immutable `ConfigPreparationReleaseV1`, unique by preparation, whose digest covers the preparation/outcome/actor/time. Effective pin state is derived from preparation expiry, release, and manifest membership; neither preparation nor revision is updated in place. A released/expired loser remains history and makes only unreferenced revisions eligible for later abandonment. +- `ConfigActivationManifestV1`: primary key `activation_id`; uniqueness of one member per target per manifest and one successor per `previous_activation` (a linear append-only chain); index on `published_at`. Manifests are append-only and retained while any snapshot, receipt, or the rollback window references them; member count is bounded by resolved target count and one manifest stays <=1 MiB. Owning shard: the profile shard, matching the profile-owned publication in Section 8.2. +- `ConfigActivationMemberV1`: primary key `(activation_id, ordinal)`; unique target digest and `(activation_id, layer_id, revision_id)` within the manifest; exact canonical target, owning-shard, layer, revision/digest, preparation receipt, and target-specific effective snapshot/digest fields. The target encoding is rehashed on write; every unexpired preparation must match the activation/target/revision/snapshot tuple. Members are immutable and retained with their manifest. `member_set_digest` covers the complete sorted member tuples. A manifest with zero members, duplicate target, missing/expired preparation, missing/unavailable/abandoned revision, or any target/shard/revision/snapshot digest mismatch cannot publish. +- `config_activation_heads`: one row per profile with `(manifest_id, generation)`; advancement is compare-and-swap from `previous_activation` and commits atomically with the new manifest and all member rows. Resolvers read only through this head and reject a missing/member-count-mismatched target instead of scanning for the latest timestamp. +- `ConfigConsumerAcknowledgementV1`: primary key `(consumer, instance, activation_id)`; the latest acknowledgement per `(consumer, instance)` is authoritative; indexes on `activation_id` and `(consumer, acknowledged_at)`. Retention keeps the current acknowledgement per instance plus history bounded to the activation rollback window; rows are <=4 KiB and contain no values, paths, or consumer error text. Owning shard: the profile shard. + +### 8.1 Revision semantics + +- Every patch includes expected layer revision, registry version, target resolution ID, idempotency key, and actor/access context. +- Validation resolves the full proposed snapshot, not just the changed keys. +- Unknown, removed, wrong-type, out-of-range, floor-weakening, ambiguous-target, stale-resolution, and incompatible-consumer changes fail before persistence. +- A successful single-owner patch appends one immutable revision and audit record transactionally. +- Retrying the same idempotency key and canonical patch returns the stored receipt. Reusing it for different bytes returns `idempotency_conflict`. +- Competing expected revisions return a typed conflict with safe current revision, changed key IDs, and a fresh diff; no last-write-wins overwrite. +- History contains actor class, target, key IDs, before/after safe values, reason, registry version, impacts, activation, and anchors. Secret refs expose only reference identity/status changes. + +### 8.2 Atomic activation across targets + +A batch import or policy change can affect multiple owning shards. Implement a durable workflow: + +1. resolve every target at one registry/catalog watermark; +2. validate the combined effective snapshots and safety constraints; +3. append candidate immutable revisions to each owning shard with expected versions; +4. under one lifecycle lease epoch, create an immutable preparation pin in each owner-shard transaction that checks revision digest/no abandonment, materializes the target-specific effective snapshot/digest, and reserves that tuple through publication expiry; +5. in one profile-shard transaction, revalidate every unexpired preparation receipt, insert the activation manifest plus its complete ordered member set referencing each preparation/revision/snapshot tuple, verify `member_set_digest`, then advance the profile's current-activation pointer; +6. emit one activation outbox event and consumer notifications; +7. append immutable preparation-release receipts after publication acknowledgement or failure; losers may receive abandonment records only after no unexpired/unreleased pin or manifest membership remains, and only those witnessed rows become eligible for safe garbage collection after the configured window. + +Resolvers ignore every revision not referenced by the current activation manifest, so readers observe either the previous manifest or the complete new manifest. This is atomic visibility, not a distributed database transaction. If an activated shard later becomes unavailable, coverage is `Partial/Unavailable`; the resolver never silently falls back to an older layer. + +The profile-owned current-activation pointer is the single visibility boundary; it can reference a manifest only after all member rows exist in that same transaction, and the manifest never carries a singular layer/revision/snapshot shortcut. Plan 02's physical schema is `config_revision_preparations` plus `config_activation_manifests`/`config_activation_members`. Activation validation proves set equality between resolved targets, preparations, revisions, target-specific snapshots, and members before publication. Later owner-shard unavailability yields typed partial coverage; it never causes fallback to another target's snapshot. + +Merged PR #425 (`de3d05dc`, final head `d3bb28b5`) reinforces the boundary between configuration and destructive identity/store workflows. Settings may select policy and show status, but split-store consolidation is a separate offline operation: freeze both canonical store families, identify holders by path plus file/inode, acquire reservations, create and verify dual backups, recompute deterministic confirmation under reservation, execute a restartable ledger/staging workflow, preserve remapped LCM edges, verify the complete destination, and publish cutover only after proof. Saving a configuration key cannot start, bypass, weaken, or mark that workflow effective. + +### 8.3 Desired, activated, effective, and observed + +- **Desired:** latest valid saved revision requested by the authorized actor. +- **Activated:** revision included in the current activation manifest. +- **Effective:** exact generation acknowledged by the consuming component. +- **Observed:** externally inspected behavior/file/process state, which can disagree with effective claims. + +Status and UI never collapse these states.

Settings shows desired/activated/effective/observed values, source, generation, affected active-attempt count, and whether activation is hot, next-heartbeat, or workflow-mediated. Tests compare generated liveness values to plan-24 fixtures and cursor expiry/rotation values to plans 01/05/10/17 so a renamed key, unit drift, or conflicting default blocks both PRs. + +## 14. Privacy, redactor, detector, and credential controls + +The entire plan 18 policy is present in Settings and CLI, not hidden behind files or provider metadata. + +### 14.1 Visible privacy controls + +- effective `PrivacyPolicyV1` version/digest and non-disableable floor version/digest; +- enabled built-in detector set and versions; +- optional detector plugins/custom manifests, sandbox state, budgets, and health; +- confidence/action thresholds by typed secret class; +- structured provider field maps and unsupported/unknown coverage; +- drop, sanitized-marker, or protected-short-lived-quarantine action where legally configurable; +- normal/sensitive/reasoning/secret retention policies; +- bounded decode/archive/record/field sizes and timeout/fail-closed behavior; +- allow decisions by rule/field structure, expiry, owner, and synthetic regression coverage, never candidate value; +- authorized quarantine roles and hold/release policy; +- scheduled/full/resumable scan policy and last verified coverage; +- required rescan/reproject/reindex/backup/restore impact after changes. + +### 14.2 Non-disableable safety floor + +The floor enforces: + +- built-in runtime detector always active on every ingress, including hooks; +- parse/field-scan boundaries and fail-closed behavior; +- no plaintext secret in search, prompts, indexes, embeddings, logs, analytics, errors, audit, exports, fixtures, or ordinary UI/API output; +- no provider, source record, project, worktree, host, environment, request, or plugin option that disables scanning; +- no threshold below the floor's minimum protection; +- no broad exclusion that skips structural scanning; +- no unbounded decoder/archive/plugin execution; +- no protected quarantine without key service, authorization, retention, and audit; +- only plan 18 eligible wrappers at content sinks. + +Settings renders floor-controlled fields as a source-chain constraint, not as a misleading disabled toggle. A rejected weakening explains the invariant and legal stronger values. CLI/API returns `config_floor_violation` with key IDs and safe constraint metadata. + +### 14.3 Privacy change activation + +- A stricter policy takes effect for new ingress immediately through the hot runtime floor. +- Existing content receives `legacy_or_prior_policy` coverage until a rescan proves it under the new digest. +- Search/prompt/export hydration blocks records whose required receipt does not satisfy the active floor. +- Rescan, descendant invalidation, quarantine, reproject, reindex, backup verification, and restore eligibility run as explicit observable operations. +- A weaker but still floor-compliant false-positive adjustment applies only after validation and cannot reconstruct deleted plaintext or automatically rehydrate V1 sources. +- Privacy configuration history contains rule IDs, versions, classes, actions, and counts only; never candidate bytes or equality-leaking cross-domain fingerprints. + +### 14.4 Credentials + +Use a narrow protected key service/keyring port: + +```rust +pub struct CredentialReferenceViewV1 { + pub reference_id: CredentialRefId, + pub provider_kind: NativeKindCode, + pub availability: CredentialAvailabilityV1, + pub owner: ConfigTargetV1, + pub created_at: UtcMicros, + pub rotated_at: Option, + pub expires_at: Option, + pub consumers: Vec, +} +``` + +The reference has no `Display` of secret material and does not expose secret-derived fingerprint, length, prefix, account URL, username, query, or scope beyond safe declared metadata. Protected entry uses host-native prompt/stdin/keyring APIs that suppress echo and logs; configuration receives only the resulting ID. Import/export preserves an unresolved reference alias and reports binding required on the destination host. + +## 15. Autonomous curation and self-improvement + +The configuration system must encode the user's explicit product rule: curation is autonomous, not proposal-driven. + +Applies to: + +- memory/fact curation, deduplication, contradiction resolution, trust updates, and retirement; +- session reflection and summary/memory extraction; +- skill writer generation, validation, evolution, installation, supersession, and retirement within granted authority; +- schedule selection and self-improvement cycles; +- retrieval/hint outcome learning and policy calibration where enabled; +- safe maintenance curation such as stale derived-state cleanup. + +Settings exposes autonomy policy, not individual candidates: + +- enabled workflows and authoritative scope; +- schedule/cadence and concurrency; +- source eligibility, evidence/quality/trust thresholds, and retention horizons; +- compute/token/time/cost budgets; +- model/provider/credential reference; +- sandbox/capability grants and repository-write boundaries; +- retry/backoff, circuit breaker, health pause, and incident behavior; +- evaluation corpus/version and promotion quality gates; +- notification/summary verbosity; +- audit retention and outcome measurement. + +There are no “pending curation proposals,” Approve, Reject, Apply, or Roll Back controls. The autonomous workflow evaluates, validates, commits, supersedes, or retires under its active policy and writes a complete decision/effect receipt. Brain/Evolution surfaces show what happened, evidence class, policy/config digest, impact, quality, and failure state for investigation—not authorization after the fact. + +Changing autonomy configuration applies to future workflow decisions at the next safe boundary. In-flight runs remain pinned to their starting digest or stop at a declared cancellation boundary; they do not mix generations. Re-evaluating historical material is a new autonomous run with a new manifest, not manual per-item replay/apply. + +Safety floors remain mandatory: secret-like/quarantined content cannot be curated into searchable facts, fixtures, prompts, or skills; extension and repository writes remain within explicit authority; system-destructive effects can require a separate confirmation. These constraints do not create a curation approval queue. + +## 16.

Replay and evaluation + +Add a read-only Configuration Lab under `/playgrounds/configuration` and generated CLI/API equivalents. + +Inputs: + +- historical/current registry version; +- historical/current activation; +- exact `ScopeSelectorV2` and target resolution; +- host/provider/project/repository/worktree context; +- selected key/module or complete bounded snapshot; +- historical runtime/consumer acknowledgement manifest. + +Outputs: + +- complete effective values and source chains; +- old/current resolution diff; +- validation/floor/compatibility decisions; +- impact and consumer acknowledgement difference; +- resulting pinned policy/query/hook/privacy bundle IDs; +- missing historical input, substitutions, coverage, and fidelity label. + +The lab is useful for questions such as: + +- Why did this agent receive different hints than another worktree? +- Which search/retrieval configuration produced this result? +- Would the current detector policy classify this synthetic canary differently? +- Which project/provider/host layer changed capture behavior? +- Did a curation run use the expected autonomous policy and budgets? +- Does a configuration change improve replay/evaluation metrics without violating floors? + +Privacy detector replay accepts only synthetic canaries or retained sanitizer-eligible fixture references. Curation replay shows policy results and historical autonomous effects but has no approve/apply path.

Extension configuration + +Extension manifests can contribute namespaced configuration descriptors only through the owner SPI in plan 19. + +- Key namespace is bound to signed extension ID/version. +- Descriptor schemas, legal layers, merge strategies, impacts, and UI metadata pass registry validation. +- Extensions cannot shadow core keys, alter precedence globally, register a weaker privacy constraint, request plaintext secret serialization, or invent a new transport. +- Credential fields are opaque references with declared capability requirements. +- Disabling/removing an extension leaves immutable history and a typed orphaned-config state; values cannot be reassigned to another extension ID. +- Sandbox/resource/egress/privacy permissions are core-owned settings whose safety floor the extension cannot edit. +- Upgrade migrations are deterministic, versioned, reversible only as a new forward revision, and tested against retained sanitized fixtures. +- Remote extensions remain outside first-default support and cannot become a reason to weaken local loopback/privacy constraints. + +## 20. Security and privacy invariants + +- All content-bearing labels, descriptions, notes, imported strings, and custom detector metadata cross plan 18's `Unclassified -> Classified -> Sanitized -> sink-eligible` path. +- Secret values and secret-derived identifiers never enter SQLite config rows, history, audit, SSE, logs, metrics, error text, response handles, browser state, URLs, exports, fixtures, or search indexes. +- Authorization precedes target expansion, layer reads, history, export, mutation, credential status, and drift observation. +- Same-profile access does not imply access to protected quarantine or foreign host state. +- Configuration mutations require loopback-authenticated/current-session access in the first V2 default, CSRF protection for browser commands, idempotency, expected revision, and audit. +- Request overrides cannot alter privacy floor, authorization, storage ownership, audit, retention holds, extension capability grants, or destructive-operation confirmation. +- Safe floor manifests are build/release integrity inputs and are signed/digested in runtime handshakes. +- A stale client cannot submit an unknown old enum/default and have the server reinterpret it. Registry mismatch returns a typed refresh/new-session/update error. +- Imports, exports, generated docs/examples, saved drafts, migration fixtures, and staged revisions receive secret scans and bounded archive handling. +- Config logs use key IDs, layer IDs, versions, result codes, counts, and durations only.

Every current command, tool, resource, protocol method, and host behavior receives an explicit keep/replace/remove disposition; every surviving binding invokes one application use case and renders one typed result consistently. + +**Architecture:** [`08-tool-catalog-crate.md`](08-tool-catalog-crate.md) owns stable capabilities, use cases, binding IDs, effect metadata, and generated surface definitions. [`09-application-crate.md`](09-application-crate.md) owns execution and canonical `ApplicationResponse` views. A small pure `tracedecay-presentation` crate converts only sealed typed views into a transport-neutral document model and renders Markdown or terminal text; canonical JSON serializes the same view without passing through the document model. Generated CLI and MCP adapters resolve the same [`ScopeSelectorV2`](16-cross-project-repository-worktree-scope.md), call the same application port, map the same errors, and apply catalog-declared output, pagination, privacy, and budget policy. The root MCP adapter uses the official Rust MCP SDK behind a pinned protocol/conformance boundary, owns lifecycle/session/framing only, and generates tools, resources, prompts, completion, notifications, and task support from the catalog. HTTP/SDK JSON, NDJSON, and SSE remain owned by plans [`10`](10-api-crate.md) and [`17`](17-official-public-api-and-sdks.md); MCP Streamable HTTP is a distinct protocol endpoint, not a REST wrapper. + +**Normative dependencies:** [`01-domain-crate.md`](01-domain-crate.md), [`05-query-crate.md`](05-query-crate.md), [`08-tool-catalog-crate.md`](08-tool-catalog-crate.md), [`09-application-crate.md`](09-application-crate.md), [`10-api-crate.md`](10-api-crate.md), [`12-root-compatibility-migration.md`](12-root-compatibility-migration.md), [`16-cross-project-repository-worktree-scope.md`](16-cross-project-repository-worktree-scope.md), [`17-official-public-api-and-sdks.md`](17-official-public-api-and-sdks.md), [`18-secret-detection-redaction-and-private-data-safety.md`](18-secret-detection-redaction-and-private-data-safety.md), [`19-system-defragmentation-convergence-and-extensibility.md`](19-system-defragmentation-convergence-and-extensibility.md), [`20-configuration-control-plane.md`](20-configuration-control-plane.md), [`22-incremental-context-scout-and-suggestion-envelopes.md`](22-incremental-context-scout-and-suggestion-envelopes.md), [`23-session-lcm-temporal-retrieval-and-evaluation.md`](23-session-lcm-temporal-retrieval-and-evaluation.md), and [`24-canonical-task-plan-graph-and-multi-agent-executor.md`](24-canonical-task-plan-graph-and-multi-agent-executor.md). + +**Normative MCP baseline (refreshed 2026-07-10):** the current stable revision is [`2025-11-25`](https://modelcontextprotocol.io/docs/learn/versioning).

The adapter uses the [official Rust SDK](https://rust.sdk.modelcontextprotocol.io/) at an exactly pinned, conformance-tested release. The implementation PR refreshes the current stable revision; a draft revision never changes a release contract silently. + +--- + +## 1. Contract lock + +1. A user intent maps to one `UseCaseId`; a concrete exposure maps to one `BindingId`. CLI, MCP, HTTP, SDK, dashboard, hook, skill, and automation names are bindings, never separate implementations. +2. The capability catalog is the sole source of names, descriptions, aliases, parameter schemas, defaults, scope requirements, effect class, auth grants, output formats, pagination, budgets, examples, availability, lifecycle, and replacement instructions. +3. The application layer returns a sealed typed semantic view. CLI/MCP renderers cannot query stores, infer missing fields, patch labels, reinterpret errors, or traverse raw `serde_json::Value`. +4. MCP text content defaults to compact Markdown while current-protocol tool results always carry schema-valid canonical `structuredContent`; explicit `format=json` controls the text representation for clients that need a JSON echo. CLI human output defaults to deterministic terminal text and machine callers opt into canonical JSON explicitly. JSON never means “the JSON-RPC wrapper containing a string containing JSON.” +5. Markdown, terminal text, table rows, JSON, NDJSON, and dashboard components derive from the same typed view and field descriptors. A renderer cannot silently drop a result, coverage item, active marker, truncation state, or retry instruction. +6. `ScopeSelectorV2` and the matching pinned `ScopeResolutionV2` are the only scope contracts. CWD may seed an explicit selector only where the catalog declares that default; it never resolves ambiguity by first match. +7. Repository, project, checkout, worktree, branch/ref, snapshot, graph generation, profile, provider, host, session, workflow, and agent filters retain distinct typed identities. `path`, `project`, `project_path`, `project_root`, `root`, and `cwd` do not remain competing semantic selectors. +8. Every mutation declares one execution mode: direct idempotent commit, explicitly confirmed destructive command, autonomous policy effect, resumable workflow, or internal host lifecycle event. There is no universal preview/apply abstraction. +9. Configuration edits use direct validate-and-save with optimistic concurrency. Every non-secret setting, including redactor/privacy/detector configuration, is navigable in Brain Settings and generated `tracedecay config` commands as required by plan 20. +10. Curation is fully autonomous. No V2 CLI command, MCP tool, HTTP route, dashboard action, skill, or generated client exposes per-item preview, approve, reject, apply, install, promote, or rollback for memory/fact curation, session reflection, skill evolution, or related self-improvement. +11. Destructive system operations outside curation may require explicit confirmation and may expose recovery/compensation. This does not create a curation approval queue. +12. Collection results use authenticated opaque cursors and deterministic ordering. A boolean `truncated` plus an unrecoverable prefix is not pagination. +13. Transport-size truncation is always explicit and recoverable through a scoped typed retrieval anchor, or the operation fails with a safe budget problem. No handler invents a private compaction envelope. +14. Success, partial success, empty-complete, empty-incomplete, unavailable, denied, ambiguous, stale, redacted, conflict, pending, and failed are distinct typed states across all surfaces. +15. Safe rendering is mandatory after sanitization and authorization. ANSI, Markdown, terminal controls, paths, labels, errors, examples, response handles, and generated docs all pass plan 18's sink firewall. +16. Current aliases and V1 behavior exist only in frozen inventory and the differential harness after their declared cutoff. There is no permanent dual namespace or silent behavior shim. +17. Generated inventories and conformance fixtures cover every command path and every tool definition, including hidden commands, conditional tools, aliases, defaults, routing-only arguments, and unavailable bindings. +18. MCP lifecycle is a connection state machine. `initialize` is first, protocol/capabilities are negotiated, `notifications/initialized` gates operation, and shutdown/drain/reconnect cannot be implemented as handler-local no-ops. +19. MCP primitive choice follows interaction ownership: tools are model-controlled operations, resources are application-controlled context, prompts are user-controlled recipes, and completion applies only to prompt/resource-template arguments. A convenience cannot be exposed as the wrong primitive merely because tools are widely supported. +20. MCP semantic parity with CLI does not imply wire identity. JSON-RPC errors versus tool execution errors, `structuredContent`, content blocks/resource links, progress/cancellation, list notifications, subscriptions, task augmentation, stdout/stderr, and CLI exit codes retain their native transport contracts. +21. An advertised MCP capability is a tested promise. The server never advertises `listChanged`, subscription, logging, prompts, completion, sampling, elicitation, or task support unless the corresponding send/receive path, authorization boundary, and host conformance fixture exist. +22. Plan 24 domain work items/attempts and MCP protocol tasks are distinct identities. MCP task augmentation is only an asynchronous execution envelope around an `OperationRef`; it never aliases `WorkItemId` or `ExecutionAttemptId`. +23. No V2 MCP resource teaches callers to query an internal database or exposes a physical schema as a supported product API. Durable evidence resolves through typed resources/retrieval anchors and application use cases. + +## 2. Source audit and concrete fragmentation evidence + +### 2.1 Evidence path and limitation + +The planning probe first called `tracedecay_context` through MCP with the explicit redesign worktree. MCP was degraded because startup project resolution found many projects. The equivalent CLI call with `--project /home/zack/projects/tracedecay` then failed closed on an identity-cutover conflict between preserved selected and legacy shards. No store was changed. The audit therefore used bounded reads of the current worktree's CLI/MCP/renderer sources and the installed 0.0.47 command/tool registries. + +This failure is itself a required regression: explicit worktree/project selection must reach one typed ambiguity/identity problem with candidates and a safe consolidation action. MCP and CLI must not print different startup guidance, suggest initialization for an existing split store, or make explicit selection ineffective. + +Primary current paths inspected: + +- `src/cli.rs`, `src/cli/automation.rs`, and the native command modules; +- `src/tool_command.rs` and `src/tool_command/args.rs`; +- `src/mcp/tools/definitions.rs` and `definitions/session.rs`; +- `src/mcp/tools/handlers/**`, `render.rs`, and `renderers.rs`; +- `src/mcp/response_handles.rs`, `project_route.rs`, and `dispatch_policy.rs`; +- existing V2 plans 08–10 and 12, 16–20. + +The normative publication snapshot is [master §2.6](../2026-07-09-tracedecay-brain-rewrite.md#26-current-master-accepted-changes) plus [plan 13](13-research-provenance-and-context-anchors.md). V2 absorbs ordinary-profile Hermes, proxy-before-store, bounded catalog refresh, fact rank/counters, exact analytics, release, and consolidation/recovery into generated bindings/handshakes/views rather than adapter-local inventories or renderers. + +Merged #425 requires one cataloged offline split-store-consolidation workflow, not transport-local migration flags: status/plan, deterministic confirmation challenge, start/resume/status/cancel-before-cutover, verification report, and recovery. CLI/MCP/API render the same typed view for canonical platform identities, path-plus-file/inode holder/reservation coverage, dual backup receipts, restartable ledger/staging, row/payload/LCM/fact/feedback dispositions, remapped-edge verification, and proof-gated cutover. Ordinary output never reveals holder command lines, unauthorized raw paths, backup secrets, confirmation material, or quarantined content; no surface can skip verification or silently initialize/select a store. + +### 2.2 Current registry drift + +The checked-out source constructs 104 MCP definitions before host capability filtering. `ast_grep_rewrite` is conditionally removed, so a matching source build exposes 103 or 104. The installed `tracedecay 0.0.47` reports 103 and includes `ast_grep_search`/`ast_grep_rewrite` but not source-defined `move_symbol`. Plan 08's older human baseline lists 102 and omits both `ast_grep_search` and `move_symbol` while already requiring a refresh for merged PR #414. + +This proves that counts, source arrays, runtime registration, category output, installed binaries, help, plans, and release state can disagree. V2 inventories therefore record: + +- source commit and binary version; +- full pre-filter definition set; +- installed/advertised set plus unavailability reasons; +- host capability probe digest; +- handler/renderer/route binding presence; +- generated catalog/protocol digest; +- exact additions, removals, replacements, and unexplained drift. + +A numeric count alone never passes the gate. + +### 2.3 Current format and renderer inconsistencies + +The current source demonstrates the failure modes this plan eliminates: + +- `FORMAT_CAPABLE_TOOL_NAMES` is a hand-maintained 99-name allowlist separate from the 104-definition registry. +- `dsm`, `files`, `sessions_for`, `type_hierarchy`, and `workflows` render through Markdown-capable handlers but do not receive the shared `format` input schema. Some are simultaneously named by the unused `tool_defaults_to_markdown` predicate. +- `tool_defaults_to_markdown` is exported but has no production consumer, so it can disagree with actual handler behavior without changing runtime output. +- all injected `format` descriptions say Markdown is the default, but schema presence and handler routing are independent lists. +- several handlers use dedicated renderers; others feed arbitrary `serde_json::Value` through `generic_md`; past source comments document a real case where `unsafe_patterns` went through the diagnostics renderer and falsely displayed no findings. +- project registry rendering has bespoke code to preserve `projects`, `project_tree`, `summary`, `limit`, `truncated`, and active markers on missing-registry paths; the invariant is not enforced for other result families. +- one global 15,000-character cap is applied after rendering, while LCM handlers have additional contract-specific compaction tiers and can report `compacted_no_handle`. +- response handles are project-root local, expire after 24 hours, and require callers to remember the same project selector. Some paths remain irreversibly truncated when a root is unavailable. +- MCP `format=json` serializes the semantic payload into `content[*].text`; `tracedecay tool --json` instead prints the raw tool result wrapper. Combining the concepts can yield a JSON envelope whose `text` is another JSON string. +- `tracedecay tool --dry-run` is a transport-side parse/validation switch, but edit/use-case schemas may also define semantic `dry_run`; the reserved flag intercepts the name and forces callers to use whole-object JSON to express the semantic field. +- routing keys such as `project_root`, `storage_scope`, `hermes_home`, `response_handle_project_root`, and `cwd` bypass normal schema validation through a separate allowlist. +- profile-scoped LCM and first-touch store tools have additional CLI allowlists that must manually match definitions, daemon behavior, and generated Hermes code. +- native commands use `--json`, `--export json|csv`, `--jsonl`, colored console tables, prose, or no machine format according to local implementation. +- normal result/progress text is inconsistently written to stdout or stderr. Some command modules call `process::exit` directly, while others return `TraceDecayError`. +- `tracedecay status` emits the full ANSI/true-color half-block dashboard even when stdout is piped with `TERM=dumb` and `NO_COLOR=1`; noninteractive agents receive a bitmap-like flood instead of bounded plain or typed status (FM-116). +- at least one invalid output mode (`cost --export `) prints an error locally instead of sharing typed validation and a guaranteed nonzero exit. +- limits and ordering are handler-local; many lists return a cap or `truncated` boolean without an opaque resumable cursor. + +Every item above becomes a fixture before V2 adapter work begins. + +### 2.4 Current MCP protocol fragmentation + +The refreshed source audit used the installed 0.0.52 CLI against the explicit redesign worktree, then inspected the indexed MCP symbols. It found a protocol implementation that has outgrown its hand-written shape: + +- `src/mcp/server.rs` hard-codes protocol revision `2024-11-05`, returns capabilities without negotiating the request version, and treats `initialized` as a compatibility no-op rather than a connection-state transition. +- `McpMethod` recognizes only initialize, tools list/call, resources list/read, ping/log-level acknowledgement, one private hook notification, and unknown. Prompts, resource templates, completion, resource subscribe/unsubscribe, progress, cancellation, roots-list changes, client responses, sampling, elicitation, and protocol tasks have no first-class dispatch path. +- `logging/setLevel` is acknowledged without maintaining a connection-local severity filter. Update warnings are pushed through a global pending-notification vector, while `tools.listChanged` delivery lives separately in daemon proxy code. Advertised capabilities and actual notification owners can therefore drift. +- `tools/list` and the five static resources are built in server/definition code without protocol pagination. The resources expose a raw SQLite schema and explicitly instruct callers to query internal storage, contradicting the V2 application boundary and the installed CLI skill's no-raw-database guardrail. +- no live tool defines `outputSchema` or returns `structuredContent`; machine JSON is text nested inside the result content. Tool execution errors, semantic failure detection, update notices, staleness banners, metrics, and automation notices are mutated into the result after handlers return. +- the main connection loop reads one line, awaits the complete handler, drains global notifications, then reads again. It cannot receive `notifications/cancelled`, client responses to server requests, or root changes while a long request is executing. Shared-daemon connections reuse engine state but do not have a complete isolated MCP session actor. +- `src/mcp/degraded.rs`, replay transport, daemon handshake interception, server routing, definition construction, dispatch allowlists, renderer selection, project routing, response handles, and analytics each own part of the protocol. The 3,800-line definitions file and 3,200-line server are symptoms of missing generated boundaries, not files to preserve. +- the global 15,000-character renderer cap creates a private `tracedecay_retrieve`/24-hour project-cache protocol instead of returning a typed MCP resource link backed by the canonical retrieval-anchor record. + +These findings become frozen source fixtures. The V2 design does not incrementally add more match arms to this stack; it replaces the protocol implementation after differential and host conformance pass. + +## 3. Complete current CLI inventory and required disposition + +The generated recursive clap inventory is authoritative. The following human matrix is an audit anchor and must remain complete until the V1 cutoff. + +| Current path family | Every current path | V2 disposition | +|---|---|---| +| Core index and status | `init`, `sync`, `status`, `list`, `wipe`, `gitignore` | Bind typed project enrollment, capture/index workflow, system status, registry query, confirmed destructive retirement, and configuration use cases. Remove local output/scope logic. | +| Generic tool bridge | `tool`, generated `help` | Keep a generated direct binding bridge, but make canonical input/output semantics unambiguous; discovery comes from the catalog. | +| Agent integration | `install`/`claude-install`, `reinstall`, `update-plugin`/`update-plugins`, `uninstall`/`claude-uninstall` | Replace aliases at cutoff with cataloged host-integration workflows, effect receipts, safe progress, and one current name. | +| Runtime surfaces | `dashboard`, `serve`, `daemon run`, `daemon install-service`, `daemon uninstall-service`, `daemon restart`, `daemon status` | Bind lifecycle workflows/status; generated auth/effect/progress/output rules. | +| Update lifecycle | `upgrade`, `update`, `channel`, hidden `post-update` | Separate query/config/direct workflow/internal lifecycle bindings. Parent-child lease token remains internal and never appears in public help/output. | +| Accounting | `current-counter`, `reset-counter`, `disable-upload-counter`, `enable-upload-counter`, `cost`, `bench`, `gain`, `monitor` | Consolidate query/config/command/stream use cases; canonical JSON/NDJSON and terminal views replace local tables/export switches. | +| Diagnostics | `doctor`, `lsp servers` | Share typed system status/problem/remediation views; never print a second error taxonomy. | +| Sessions | `sessions ingest`, `sessions search`, `sessions git-backfill`, `sessions unfinished` | Replace ingest/backfill with observable workflows; all reads use canonical session/message/Git scope, cursor, coverage, and result views. | +| Analytics | `analytics diagnostics`, `analytics sync` | Typed query plus import workflow; no output or scope special case. | +| Project registry | `projects list`, `projects search`, `projects context` | Preserve stable empty/missing shapes, safe labels, active state, candidates, cursor, and explicit All/exact scope. Retire old root `list` after parity. | +| Branches | `branch list`, `branch add`, `branch remove`, `branch removeall`, `branch gc`, `branch autotrack status`, `branch autotrack enable`, `branch autotrack disable` | Recast reads, configuration, enrollment, and confirmed retirement as distinct use cases; `removeall` gets a normalized name before cutoff. | +| Memory | `memory status`, `memory curate` | Keep status. Remove manual curate preview/apply/LLM-ops surface; autonomous curation exposes policy, health, runs, decisions, outcomes, pin/protect/exclude, feedback, pause/resume, and run-now only. | +| Automation config | `automation config get`, `explain`, `enable`, `disable`, `set` | Replace with generated plan-20 `config` use cases; automation module is one navigable branch of the complete registry. | +| Automation runs | `automation run memory-curation`, `session-reflection`, `skill-writing`; `automation runs list`, `view`, `artifact` | Remove dry-run/proposal semantics. Keep autonomous run-now and read-only run/artifact/outcome views with pinned policy/config/eval digests. | +| Managed skills | `automation skills list`, `view`, `draft`, `update`, `approve`, `disable`, `archive`, `restore`, `install` | Remove per-item authoring/approval/promotion bindings from autonomous evolution. Replace with inventory, history, decisions, outcomes, authority, pin/protect/exclude, health, and feedback. | +| Fact proposals | `automation facts list`, `view`, `apply`, `reject` | Remove proposal queue and item mutations. Replace with autonomous decision/effect history and policy/quality controls. | +| Store migration | `migrate plan`, `export`, `apply`, `verify`, `reconstruct`, `registry-gc`, `rollback`, `cleanup-sources` | Map to typed inventory, export, verified migration workflows, confirmed destructive cleanup, and recovery. Curation autonomy does not remove system migration safety. Rename V1 ceremony terms where the V2 workflow model supersedes them. | +| Hidden extraction | `extract-worker` | Internal host binding only; generated protocol/version handshake and machine-only output. | +| Hidden Claude hooks | `hook-pre-tool-use`, `hook-prompt-submit`, `hook-stop`, `hook-claude-session-start`, `hook-claude-post-tool-use`, `hook-claude-subagent-start` | Generated provider descriptor and internal hook bindings; never hand-authored clap commands. | +| Hidden Kiro hooks | `hook-kiro-pre-tool-use`, `hook-kiro-prompt-submit`, `hook-kiro-post-tool-use` | Same internal hook contract. | +| Hidden Cursor hooks | `hook-cursor-subagent-start`, `hook-cursor-post-tool-use`, `hook-cursor-before-submit-prompt`, `hook-cursor-pre-compact`, `hook-cursor-after-file-edit`, `hook-cursor-session-start`, `hook-cursor-session-end`, `hook-cursor-after-shell`, `hook-cursor-workspace-open`, `hook-cursor-stop` | Same internal hook contract. | +| Hidden Codex hooks | `hook-codex-session-start`, `hook-codex-user-prompt-submit`, `hook-codex-subagent-start`, `hook-codex-post-tool-use`, `hook-codex-post-compact` | Same internal hook contract. | + +Plan 24 adds generated V2-only `initiative`, `plan`, `task`, `executor`, `scheduler`, `task-view`, and `task-graph` groups plus audience-filtered executor lifecycle bindings. They are not shoehorned into legacy `automation`, `projects`, `branch`, or generic `tool` semantics. The binding manifest preserves exact commands `work_items.record_attestation`, `work_items.record_review`, `work_items.record_decision`, `work_items.record_exception`, `work_items.handoff`, `work_items.reopen`, `work_items.reverse_transition`, `task_offers.accept|decline|revoke`, `attempts.heartbeat|progress|complete|block`, `context_packets.accept`, `task_notifications.create|update|delete`, and protected `task_views.share.plan`, `task_views.share.start`, `task_views.share.revoke`. `task_offers.accept` is the sole public execution-admission binding; no CLI/MCP alias named `work_items.acquire_lease` exists. Every CLI/MCP/HTTP/SDK/dashboard exposure maps to one catalog use case and sealed task/plan/executor view; compact output always retains canonical IDs/versions, blockers, coverage, packet/lease/route status, anchors, and legal next actions. Fence proofs, credentials, protected logs, and private sibling content never render. + +Research provenance adds catalog operation IDs `research.manifests.list/get/create_version` and the canonical evidence operation family `retrieval_anchors.metadata_batch_get`, `retrieval_anchors.resolve`, and `retrieval_recipes.execute`. Generated bindings may accept `ResearchAnchorId` only for manifest navigation; evidence metadata/resolution/recipe execution accepts canonical `RetrievalAnchorId`/`RetrievalRecipeV1` and never treats safe metadata as payload authority. No CLI, MCP, HTTP, SDK, dashboard, or export binding invents a research-specific resolver or treats a manifest-entry ID as payload authority. + +Search evaluation uses only the canonical plan-15 family: + +```text +reads: retrieval.{corpus_versions,qrel_versions,candidate_pools,judgments,adjudications,evaluation_runs,evaluation_reports,profiles}.list|get +commands: retrieval.corpus_versions.create|freeze; retrieval.qrel_versions.create|freeze; retrieval.candidate_pools.create; retrieval.judgments.record|supersede; retrieval.adjudications.record; retrieval.evaluation_runs.run|cancel; retrieval.evaluation_reports.publish; retrieval.fixtures.promote; retrieval.profiles.publish|activate +``` + +Each read generates one semantic CLI binding, MCP tool, read-only MCP resource/resource-template where addressable, HTTP/SDK binding, and Search Quality UI view metadata from the same typed result. MCP `resources/list` discovers resources; it never replaces the canonical `.list` use case. Commands generate CLI/MCP/HTTP/SDK/UI actions and no writable resource. No transport may add `eval`, `benchmark`, `golden`, `retrieval.fixtures.list/get`, or any other alias/use case absent above. + +The extractor also records every flag, positional, alias, conflict, required relationship, enum/range, default, env source, hidden state, TTY behavior, stdin/file behavior, color behavior, output family, exit path, effect, and called handler. A command path without a reviewed disposition blocks catalog generation. + +## 4.

TraceDecay pins the SDK/protocol versions and wraps them behind its root adapter; catalog generation supplies definitions and dispatch rows instead of per-handler macros or match arms. If a required stable-protocol feature is missing upstream, one bounded protocol adapter may be registered in plan 19's adapter ledger with an upstream issue, conformance fixtures, and a deletion release. No application behavior enters that adapter. + +`McpSessionContext` is isolated per client connection and contains only negotiated protocol revision, client implementation/capabilities, authenticated principal/grants, captured roots, pinned `CatalogSnapshotRefV1`, config-registry digest, resolved default scope candidate, logging level, request/task cancellation registry, subscriptions, and list generations. The shared daemon engine, stores, caches, and application services are not connection state. A session state machine enforces: + +1. `initialize` is the first request; only ping is tolerated around initialization as the stable specification permits. +2. The server compares the client revision to its generated supported set. It returns the same revision when supported or its current supported revision otherwise; an incompatible client disconnects/updates before application/store access. V2 does not retain the current `2024-11-05` live protocol. +3. The initialize result advertises only implemented standard capabilities and carries `CatalogSnapshotRefV1`, config-registry digest, and daemon generation in namespaced `_meta["io.tracedecay/catalog-v1"]`. +4. Normal requests begin only after `notifications/initialized`. Server-to-client requests other than allowed ping/logging do not run earlier. +5. Every operation captures session/auth/catalog/scope state once. Concurrent requests may complete out of order by JSON-RPC ID, while one bounded writer task serializes valid protocol messages; no task writes directly to stdout. +6. Reader progress never waits for a long handler. Cancellation, client responses, root changes, pings, and drain signals remain processable while application work runs under bounded per-principal and per-capability concurrency. +7. Drain stops admission, returns a retryable typed problem for new calls, propagates cancellation only at cataloged safe boundaries, lets non-cancellable effects reach a durable receipt/reconciliation state, flushes audit state, and closes. Reconnect always performs a fresh initialize; no daemon proxy replays an old session as if it were current. + +Bootstrap failure does not create a second “degraded MCP server.” Catalog and safe system/project/repair availability can initialize without opening a selected project store. The same generated definitions remain visible with typed availability; calls that require blocked identity/storage return one application problem. Recovery updates availability and emits a real list/resource change only if the authorized primitive set changed. + +#### 5.4.1 Catalog refresh and dynamic lists + +- `tools/list`, `resources/list`, `resources/templates/list`, and `prompts/list` are generated, access-filtered, and protocol-paginated. Their opaque cursor binds principal, protocol revision, catalog/list generation, and ordering, so pages never mix snapshots. +- Missing host prerequisites remain visible as safe unavailable tool metadata when visibility is authorized; a capability is hidden entirely when even its existence is unauthorized. Counts, completion, list-change events, and errors cannot reveal hidden rows. +- A catalog or grant change increments the affected primitive generation. A per-session notification hub emits at most one coalesced `notifications/tools/list_changed`, `notifications/resources/list_changed`, or `notifications/prompts/list_changed` for that generation, and only when the matching capability was advertised. +- Once a session is marked refresh-required, a call that depends on a replaced binding fails with `capability_replaced`/`client_update_required`; it never dispatches by a stale name to new semantics. A complete list refresh atomically pins the new generation. A protocol or binary-major change requires reinitialize/reconnect instead. +- `resources/subscribe` is offered only for mutable typed resources with an application/projector change feed. `notifications/resources/updated` carries the authorized URI, not payload. Reads and every delivery reauthorize; revocation removes the subscription. Slow consumers receive one coalesced update/gap instruction and reread rather than accumulating unbounded deltas. +- `logging/setLevel` stores a connection-local syslog threshold. Protocol log notifications contain safe structured diagnostics/correlation IDs, never result payloads, secrets, raw prompts, or progress that belongs in `notifications/progress`. + +#### 5.4.2 Roots, scope, and client capability use + +If a client advertises roots, TraceDecay requests `roots/list` after initialization and reacts to `notifications/roots/list_changed`. Roots are untrusted scope candidates only: they are canonicalized through plan 16, authorized, and compared to registered projects/worktrees. They never override an explicit `ScopeSelectorV2`, choose the first matching checkout, or silently change the active graph. A changed root invalidates the candidate and requires a new resolution; it does not mutate an in-flight request. + +Sampling and elicitation are optional client capabilities, not generic fallbacks: + +- client sampling may be requested only by an explicit foreground catalog use case or a playground/evaluation operation whose policy, sanitized prompt manifest, model/tool budget, approval, result visibility, and audit receipt are visible. Plan 22's daemon/Spark scout and autonomous curation use their owned model gateway; they never silently spend the connected host's model through MCP sampling. +- sampling with tools requires the client's negotiated `sampling.tools` capability and a generated bounded tool subset. The client remains free to choose/deny the model and response; sampled content re-enters as untrusted input and passes plan 18. +- form elicitation cannot request a password, API key, access token, confirmation secret, or payment credential. URL elicitation is the only MCP path for sensitive/OAuth interaction, uses validated HTTP(S) URLs, binds state to the principal/session, and never shells out. +- elicitation may resume an application operation already in `WaitingForInput`; it does not invent item approval for autonomous curation. A client without the capability receives `interaction_required` and an operation-specific safe next action. + +#### 5.4.3 Progress, cancellation, and MCP protocol tasks + +For an ordinary request containing `_meta.progressToken`, the adapter maps cataloged application progress into monotonic `notifications/progress`; tokens are opaque, session-local, and never persisted as domain identity. `notifications/cancelled` cancels only the referenced in-flight request in the same direction/session and produces no response after a successful cancellation. Completion/cancellation races are deterministic and audited. + +Long-running use cases may declare MCP `execution.taskSupport = optional|required` only when the application returns a durable `OperationRef` with bounded TTL, status, result, cancellation boundary, principal/scope binding, and rate limits. `McpTaskId` is an opaque protocol projection of that operation. `tasks/list|get|result|cancel` never query or mutate plan 24 task/work-item tables by ID coincidence; a plan-24 work item is visible through its own generated TraceDecay resource/tool bindings. Ordinary request cancellation uses `notifications/cancelled`; task-augmented execution uses `tasks/cancel`. + +#### 5.4.4 Transports and authorization + +Stdio is the mandatory local host transport. It authenticates the installation/launch context, accepts only MCP JSON on stdout/stdin, sends diagnostics only to stderr or negotiated logging, minimizes inherited environment, and applies catalog grants exactly like every other surface. + +An optional `/mcp` endpoint implements current Streamable HTTP directly through the official SDK; it is not `/api/v2`, an OpenAPI bridge, or the removed HTTP+SSE transport. It validates `Origin`/Host, binds loopback by default, accepts the negotiated `MCP-Protocol-Version` header, uses cryptographically strong `MCP-Session-Id` where stateful sessions are enabled, supports safe SSE resumption without cross-stream replay, and applies bounded connection/session/request queues. Loopback authentication consumes plan 17's scoped token registry. Any future non-loopback deployment must implement the official MCP OAuth protected-resource/resource-indicator contract, TLS, audience validation, incremental scopes, and a separate reviewed threat model. TraceDecay never accepts tokens in URLs/tool arguments, passes the client token through to another service, or uses MCP annotations as authorization. + +## 6.

The presentation crate has no edge to store/capture/projectors/query/policy/hooks/API implementations. No root-local presenter is permitted after this crate lands. + +## 7. Typed view and presentation model + +### 7.1 Semantic views + +Application use cases return domain-specific transport-eligible structs, not arbitrary maps: + +```rust +pub struct SearchResultsViewV2 { + pub query: SafeQuerySummary, + pub items: CursorPage, + pub facets: SearchFacetSummaryV1, + pub ranking: RankingReceiptV1, +} + +pub struct ProjectRegistryViewV2 { + pub projects: CursorPage, + pub project_tree: Vec, + pub summary: ProjectRegistrySummaryV2, + pub active_project_id: Option, + pub registry_state: RegistryCoverageV2, +} + +pub struct CommandReceiptViewV2 { + pub operation: OperationRef, + pub outcome: CommandOutcomeV2, + pub effects: Vec, + pub recovery: RecoveryDispositionV2, +} +``` + +Every content-bearing field is a plan-18 eligible wrapper or an explicit redacted/denied/unknown variant. `ApplicationResponse` carries scope, snapshot, coverage, freshness, redactions, retention, limits, and warnings once. + +### 7.2 Human document IR + +Presentation converts a typed view into a bounded semantic document: + +```rust +pub struct HumanDocument { + pub title: CatalogSafeText, + pub summary: Vec, + pub body: Vec, + pub coverage: CoverageBlock, + pub next_actions: Vec, +} + +pub enum DocumentBlock { + Heading(HeadingBlock), + FieldList(FieldListBlock), + ItemList(ItemListBlock), + Table(TableBlock), + Code(CodeBlock), + Notice(NoticeBlock), + Progress(ProgressBlock), + Empty(EmptyStateBlock), + Truncation(TruncationBlock), +} +``` + +The IR contains typed cell values, links/anchors, severity, and wrapping hints rather than embedded Markdown/ANSI. Markdown and terminal renderers escape from this IR. JSON never serializes this IR; it serializes the original semantic view. + +### 7.3 Generated presentation traits + +```rust +pub trait PresentHuman: TransportEligibleView { + const PRESENTATION_ID: PresentationId; + fn to_document(&self, context: &PresentationContext) -> HumanDocument; +} + +pub struct PresentationContext { + pub binding: BindingId, + pub locale: LocaleId, + pub width: Option, + pub color: ColorPolicy, + pub detail: DetailLevel, + pub budget: PresentationBudget, +} +``` + +Implementations are domain-clustered and generated/checked against field descriptors. There is no catch-all raw JSON renderer. Unknown extension views must supply a versioned presentation plugin or fall back to canonical JSON only with an explicit unavailable-human-format reason. + +## 8. Output format contract + +### 8.1 Format matrix + +| Surface | Default | Explicit formats | Rules | +|---|---|---|---| +| CLI query/status | `human` | `human`, `table`, `markdown`, `json` | Default never changes with TTY. TTY affects color/width only. `--json` is a generated alias for `--format json`, not another mode. | +| CLI stream/watch | `human` | `human`, `ndjson` | NDJSON is one complete typed event per line with initial metadata and terminal coverage/summary. `--jsonl` aliases `--format ndjson` until cutoff. | +| CLI export | operation-specific | `ndjson`, `json`, `csv`, `parquet` only where cataloged | Export formats are schema-versioned data products, not console rendering. CSV remains only for flat declared schemas. | +| MCP | `markdown` | `markdown`, `json` | JSON is canonical semantic data; Markdown is compact human/agent presentation. No table/ANSI. | +| HTTP/SDK | `json` | JSON plus cataloged NDJSON/export media | Follows plans 10/17 content negotiation. | +| Subscription | SSE | SSE only | Snapshot/delta/progress/gap protocol from plans 10/17; not line-oriented renderer output. | +| Dashboard | typed client view | UI components/export actions | No Markdown scraping or CLI execution. | + +### 8.2 Canonical CLI switches + +Generated public commands share only applicable global switches: + +```text +--format human|table|markdown|json|ndjson +--scope +--profile +--project +--repository +--checkout +--worktree +--ref +--snapshot +--consistency eventual|frozen|at-least-watermark +--limit +--cursor +--fields +--detail compact|normal|full +--no-color +--quiet +--verbose +``` + +Ergonomic flags are lossless builders for `ScopeSelectorV2`. They are mutually exclusive with `--scope` when they overlap. Generated help shows the canonical selector before invocation. Mutations require an explicit durable target; queries use a default only when the catalog declares it, such as profile-wide `AllAuthorized` for Brain. + +No global flag shadows a semantic input field. Transport-side schema validation becomes `tracedecay invoke --validate-input`; semantic `dry_run` is removed in favor of the use case's declared execution mode. Debugging the raw transport envelope uses a hidden developer command, never public `--json`. + +### 8.3 Canonical MCP result + +Every tool publishes generated JSON Schema 2020-12 `inputSchema` and an object-root `outputSchema`. The output is a tagged union of `{ outcome: "ok", response: ApplicationResponse }` and `{ outcome: "error", problem: SurfaceProblemV2 }`, so success and tool-execution error `structuredContent` both validate. MCP bindings accept a generated `format` enum only where human rendering is supported. The adapter returns: + +- `structuredContent`: the canonical tagged typed outcome for every current-protocol tool result; +- `content`: compact Markdown from the same typed view in default mode, including stable IDs, coverage, active target, limits, and legal next action; +- explicit `format=json`: the same canonical outcome serialized once into a text content block, while `structuredContent` remains the object; no JSON string is nested inside another semantic JSON field; +- an MCP `resource_link` plus compact summary when a durable retrieval anchor/resource is the safe bounded representation; the link never points at a project-local response-handle cache; +- namespaced `_meta` containing safe binding/catalog/protocol/request IDs and presentation receipt only, never semantic fields duplicated from `ApplicationResponse` or data a client must preserve to understand the result; +- `isError=false` for the success variant and `isError=true` for a known tool's application/validation/authorization/business failure. + +Unknown tool names, malformed JSON-RPC, invalid MCP request structure, unsupported methods, and protocol-state violations are JSON-RPC protocol errors. A well-shaped call to a known tool returns the typed tool-execution error so the model can self-correct. Raw internal failures become a safe correlation-bearing tool error unless the protocol connection itself is unusable. The default Markdown plus structured-object choice is intentional: V2 records a reviewed SHOULD-level deviation from the specification's backwards-compatibility serialized-JSON text echo in default mode, avoids doubling every human result, provides the echo in explicit JSON mode, and claims no pre-structured-content protocol compatibility. Conformance decodes Markdown-default, explicit-JSON, resource-link, success, and error paths back to the same canonical fixtures. + +### 8.4 Determinism + +- maps render in schema-defined order, never hash insertion order; +- rows sort by the use case's declared primary keys and stable ID tie-breaker; +- time uses captured request context and canonical UTC machine values; human relative time includes exact time at normal/full detail; +- sizes, durations, scores, money, tokens, paths, enums, and counts have canonical units; +- color is decoration only; stripping ANSI produces the no-color bytes except for intentional width padding; +- terminal width changes wrapping/column selection, never row membership or meaning; +- locale affects approved human labels only; machine fields/enums/decimal syntax remain stable. + +## 9. CLI information architecture and navigation + +### 9.1 One command tree + +The generated CLI groups capabilities by product domain rather than implementation history: + +```text +tracedecay brain profile-wide search, graph, timeline, inspect +tracedecay code code graph, health, diagnostics, edit +tracedecay git refs, changes, delivery correlation +tracedecay sessions sessions, messages, Turns, agents, workflows, goals +tracedecay memory knowledge status, query, autonomous curation outcomes +tracedecay automation schedules, runs, outcomes, authority, health +tracedecay config complete plan-20 settings tree +tracedecay project registry, repositories, worktrees, enrollment, sync +tracedecay system status, doctor, daemon, update, migration, accounting +tracedecay lab query/search/hint/coordination/config/privacy replay +tracedecay invoke generated direct binding bridge +tracedecay help catalog-backed discovery +``` + +The `system` group also exposes plan 17's scoped, TTL-bound, revocable local API-token surface with exact effect classes: `api token list` binds the elevated read `auth.tokens.list`, while `api token create` and `api token revoke` bind audited commands. HTTP parity is `GET /api/v2/auth/tokens`, `POST /api/v2/commands/auth/tokens:create`, and `POST /api/v2/commands/auth/tokens:revoke`; MCP/CLI bindings preserve those semantics without copying HTTP route syntax. Plan 10's per-launch bearer remains only the bootstrap credential permitted to invoke the initial `auth.tokens.create` command. + +This taxonomy is a target navigation model, not authorization to rename everything at once. Each current path receives an alias/cutoff migration, generated replacement, and differential fixture. Frequently used native paths may stay short when their meaning is already canonical. + +### 9.2 Help and discovery + +Every command/tool help page is generated from the same binding row and includes: + +- one-sentence task fit and negative guidance for commonly confused siblings; +- use-case/binding ID and lifecycle; +- availability and missing prerequisite; +- effect/auth/autonomy class; +- default scope and exact resolution behavior; +- parameters with type, units, default, range, enum, conflicts, and safe example; +- default/output formats, pagination, caps, coverage, and freshness; +- replacement/deprecation/cutoff; +- related CLI/MCP/API/SDK/dashboard/lab bindings; +- compact copyable invocations for human and canonical JSON use; +- a direct docs anchor. + +Add: + +```text +tracedecay help search +tracedecay help show +tracedecay help compare +tracedecay help available [--scope ...] [--format json] +tracedecay help schema [--format json] +``` + +Search covers names, stable IDs, old aliases, intents, task-fit phrases, inputs, outputs, product views, and skills. Unavailable capabilities remain visible with one reason and one remediation. “No result” is never used for unavailable/denied discovery. + +### 9.3 Hints and skills + +Policy/hook hints reference stable intent/capability/binding IDs and a generated summary. They never paste the full tool list. A hint may recommend the cheapest applicable binding, the exact scope it would use, and one command. Hint analytics record offered/acted/missed/corrected/suppressed outcomes by IDs, not free-text matching. + +Managed skills declare versioned capability requirements and allowed effects. Installation validates binding availability/catalog digest. Skills cannot resurrect removed aliases, invoke curation item approval paths, or teach surface-local scope/output behavior. + +## 10. Scope, project, repository, worktree, and ref parity + +### 10.1 Shared selector + +Every scoped binding receives the exact plan-16 selector and resolved snapshot. Generated surface builders expose only legal selector fields for that use case. Resolution output includes: + +- profile and privacy domain; +- selected project(s), repository/common-dir identity, checkout/worktree identity; +- branch/ref/commit/PR and graph/index generation; +- source/store shards and watermarks; +- ambiguity candidates, stale/locked/quarantined/unavailable coverage; +- default source and why it was legal; +- retry token/template when user selection is required. + +Transport routing metadata is generated from a closed `RoutingFieldDescriptorV1`; there is no validation-bypass allowlist. A field is either a canonical typed selector/ID or a transport-only keyed locator. Human/runtime strings such as `project_root`, `cwd`, `hermes_home`, `storage_scope`, and `response_handle_project_root` cannot pass through untyped: + +- display/explanation uses `SinkEligible` and never becomes a lookup key; +- lookup uses an opaque ID or `PrivacyDomainBoundLocatorDigest` computed inside the authorized resolver from a normalized path/source value; +- raw paths remain protected application inputs, never catalog metadata, metrics, logs, errors, response handles, help, or generated routing keys; +- handler/daemon/plugin code cannot add a field outside the catalog schema, and unknown routing fields fail validation before any store open; +- keyed-locator key epoch, privacy domain, source kind, normalization version, and scope are bound into the request/snapshot receipt; comparison across domains or key epochs is forbidden; +- profile-scoped and first-touch behavior is an explicit generated use case with the same resolver, authorization, problem, and coverage contract—not a CLI/MCP side list. + +Conformance tests enumerate every generated request field and fail if any field bypasses schema validation, lacks a safe-text/typed-ID/keyed-locator class, or reaches a log/error/presenter as a raw path. + +### 10.2 Required regression corpus + +Lock fixtures for: + +- two registered projects with the same basename; +- one repository with base checkout plus several parallel worktrees; +- project marker and registry identity disagreement; +- selected and legacy shard conflict from the planning probe; +- explicit worktree path while MCP startup is scoped to another checkout; +- branch name existing in several repositories; +- ref missing from current graph but available in another generation; +- all-registered search returning a session that exact load must accept with the same scope; +- profile-wide All returning partial locked/stale stores; +- safe active marker differences between current CLI and MCP project output; +- credential-bearing remote URL present in source metadata but absent from search labels/output. + +### 10.3 Labels and active markers + +One typed label view feeds all human surfaces: + +```rust +pub struct ProjectLabelViewV2 { + pub project_id: ProjectId, + pub display_name: CatalogSafeText, + pub disambiguator: Option, + pub repository_group: Option, + pub checkout_kind: CheckoutKind, + pub is_active: bool, +} +``` + +Repeated basenames use a safe parent-path/common-directory or explicit registry alias disambiguator. Remote URLs, credentials, query strings, usernames, and tokens are never labels. Markdown/terminal display `*` only as decoration derived from `is_active`; JSON carries the boolean. Missing registry returns the same outer typed collections, summary, cursor/cap, coverage, and active field shape as a populated registry. + +## 11. Effects, auth, configuration, and autonomous curation + +### 11.1 Effect classes + +The closed effect enum is owned by plan 08's `effect.rs` as `EffectSpec.execution_mode`; this plan consumes it and defines no surface-local effect mode: + +```rust +pub enum ExecutionModeV2 { + ReadOnly, + DirectCommit, + ConfirmedDestructive, + AutonomousPolicyEffect, + ResumableWorkflow, + InternalHostLifecycle, +} +``` + +Each binding exposes grants, idempotency, expected-version policy, audit schema, progress/receipt shape, cancellation boundary, and recovery. CLI/MCP annotations are generated from this enum. Read-only hosts cannot obtain mutation bindings merely through a name alias. + +MCP `readOnlyHint`, `destructiveHint`, `idempotentHint`, and `openWorldHint` are derived mechanically from this effect contract and egress policy. They are explanatory hints for trusted hosts, not enforcement inputs: every invocation still passes authenticated-principal, catalog grant, scope, plan-18 eligibility, and application policy checks. A mismatch between annotation and effect metadata blocks generation. + +### 11.2 Direct configuration + +Plan 20's complete generated `tracedecay config` tree is mandatory. `--json`/`--jsonl` are aliases for the shared format contract. Redactor, detector, privacy, retention, quarantine, source-field rules, scan schedule, false-positive policy, and non-disableable floor are visible and navigable in CLI and Brain Settings. + +Routine `config set`, `unset`, batch commit, credential-reference bind, and forward restoration validate and commit directly with expected version/idempotency. Inline impact explains hot reload, restart, new session, rescan, reproject, reindex, migration, or unsupported state. There is no forced preview/apply/rollback ceremony. + +### 11.3 Autonomous curation + +Remove these V1 public semantics after outcome/status parity: + +- `memory curate --apply`, `--llm`, and `--llm-ops`; +- automation-run `dry_run` as the only supported mode; +- fact proposal apply/reject queues; +- managed-skill draft/update/approve/install promotion queues produced by the curator; +- dashboard/API item approve/reject/apply/rollback controls; +- capability metadata suggesting curation candidates require human approval. + +Expose only policy/configuration, schedule, budgets, authority, quality floors, run-now, pause/resume, circuit-breaker health, pin/protect/exclude, feedback, history, decisions, effects, outcomes, and incident diagnostics. Autonomous runs pin catalog/policy/config/eval digests. Human views explain what happened; they do not authorize each item after the fact. + +### 11.4 Confirmed destructive operations + +Wipe, source cleanup, protected-data retirement, unsafe migration cutover, or external side effects can require an explicit confirmation token and current-version revalidation. Their names and receipts must describe the real effect. “Apply” and “rollback” are not generic framework verbs; use a domain command such as `migration cutover`, `migration recover`, or `project retire` where that is the actual operation. Move-symbol follows the same rule: `code.move_symbol.inspect` is a read-shaped preflight and `code.move_symbol.commit` is the confirmed mutation; both call plan 09's registered boundary and never select a transport-generic preview/apply mode. + +Split-store consolidation follows the stricter plan-01/02/#425 workflow. The confirmation challenge binds both frozen source manifests, canonical platform locators, reservations, dual backup receipts, disposition plan, and destination. Start/resume never accepts an ambient current store; cutover is unavailable until the exhaustive verification view reports all required proofs, including remapped LCM source-edge integrity. Cancellation after an uncertain external/cutover effect enters typed reconciliation instead of claiming rollback. + +## 12. Errors, status, stdout, stderr, and exit codes + +### 12.1 One problem model + +Application owns stable error codes. CLI and MCP map `ApplicationError` without parsing messages. `SurfaceProblemV2` is exactly the shared plan 09/10/17 problem shape — plan 10 §7.2's `ApiProblem` minus the transport-supplied RFC 9457 `problem_type`/`status` fields — with no field dropped or renamed; this plan adds only the Section 12.2 exit-class mapping: + +```rust +pub struct SurfaceProblemV2 { + pub code: ApplicationErrorCode, + pub title: CatalogSafeText, + pub detail: Option, + pub instance: RequestId, + pub retry: RetryDirective, + pub restart: Option, + pub current_binding: Option, + pub candidates: Vec, + pub invalid: Vec, + pub current_version: Option, + pub operation: Option, +} +``` + +Human output leads with the problem and exact next action. JSON returns only the typed problem envelope. Raw provider/store/parser errors are logged through the safe observability path under the correlation ID and never copied into public detail. + +### 12.2 Stable CLI exit classes + +| Exit | Class | Examples | +|---:|---|---| +| 0 | success | complete query, accepted direct command, or explicitly allowed partial result | +| 2 | usage/validation | unknown command/flag/format, invalid typed input, missing required field | +| 3 | scope/identity | not found, ambiguous, identity split, ownership unresolved | +| 4 | auth/policy | unauthenticated, denied, privacy/payload denied | +| 5 | unavailable/freshness | capability unavailable, required refresh, all selected sources unavailable | +| 6 | conflict | expected version, idempotency, cursor/snapshot/protocol mismatch | +| 7 | retryable operation | transient dependency, rate/deadline, workflow still pending when synchronous completion was required | +| 8 | failed operation | durable workflow or confirmed command failed with a receipt | +| 9 | client incompatibility | stale protocol/catalog/binding requires update/restart | +| 70 | internal invariant | safe correlation ID only | +| 130 | cancelled | user cancellation/interrupt | + +Useful partial results return 0 with `!coverage.is_complete()` unless the caller requests `--require-complete`, in which case the same response is written and exit 5 communicates the unmet contract. Empty complete and empty incomplete remain different in output. + +### 12.3 Stream contract + +- stdout contains only the selected result format; +- stderr contains human progress, retry notices, and diagnostics only when they are not part of machine output; +- `--format json|ndjson` never emits prose, ANSI, progress bars, warnings, or update notices on stdout; +- machine-relevant warnings, coverage, and progress are typed fields/events, not stderr-only information; +- `--quiet` suppresses optional human progress, never errors or result data; +- `--verbose` adds safe diagnostic events to stderr/human output and does not mutate JSON schemas; +- command modules return typed outcomes; they never call `process::exit`. + +## 13. Pagination, cursors, truncation, and retrieval anchors + +### 13.1 Collections + +All bounded collections use the one `CursorPage` envelope defined once in plan 17's contract IR (plan 17 §13.1) — `{ items, next_cursor, truncation, count_semantics, ordering }`; plan 10's `Page` and this plan's `CursorPage` are that same type, not variants, and neither plan restates its fields. + +The earlier draft's `returned` and `page_limits` fields fold into this shape without information loss: returned-row counts are part of `count_semantics`, and the applied default/hard page limits travel in the `truncation` receipt. + +Opaque authenticated cursors bind the canonical request fingerprint, access digest, resolved scope, schema/ranking/index/catalog versions, frozen watermarks, expiry, ordering cutoff, and per-shard positions. CLI exposes `--cursor`; SDKs expose bounded pagers. `--all-pages` is allowed only with explicit maximum pages/items/bytes/deadline. No SQLite transaction spans client think time. + +Do not conflate three opaque token classes: an MCP discovery cursor paginates tools/resources/prompts over one catalog/list generation; an application cursor paginates semantic query rows over pinned data watermarks; a `RetrievalAnchorId` addresses a sanitized typed payload/evidence artifact. Each has a distinct codec, audience, expiry/retention, error, and restart directive. The MCP adapter unwraps/rewraps none of them and never accepts one where another is expected. + +### 13.2 Output budgets + +Pagination limits semantic row count. Presentation budgets limit human detail. Transport budgets limit encoded bytes/tokens. These are separate receipts. A renderer may reduce optional columns/detail according to a declared presentation ladder, but it cannot remove rows without the semantic page reporting it. + +### 13.3 Retrieval anchors + +When an individual eligible field or complete encoded response exceeds a transport cap: + +- store the sanitized typed payload or eligible blob reference, not an unclassified rendered string; +- persist the canonical plan-01 `RetrievalAnchorRecordV1`, whose target binds the sanitized typed payload or eligible blob artifact to resolved scope, privacy domain, access-policy digest, source observations, snapshot, schema/catalog/data/projection versions, canonical request digest, payload-access state, provenance, expiry/durability, and retention class; +- return only that record's opaque `RetrievalAnchorId`; retrieval calls the cataloged generic `retrieval_anchors.resolve` use case, reloads `RetrievalAnchorRecordV1`, and reauthorizes the current principal rather than trusting a research entry ID or transport handle; +- expose exact omitted fields/bytes and retrieve binding; +- authorize and revalidate on retrieval; +- regenerate presentation from the typed payload where possible; +- preserve canonical retrieval-anchor identity across CLI/MCP/API when the same principal and scope permit; +- forbid a response handle as the only durable citation, saved-view, or export locator. + +MCP renders the anchor as a `resource_link` to a generated `tracedecay://v2/retrieval/{anchor_id}` resource template plus the same ID in `structuredContent`. `resources/read` reauthorizes and resolves the canonical record through the application layer. V1 `rh_*` response handles are accepted only by the frozen differential harness until cutoff and are absent from V2 definitions, prompts, resources, hints, and live dispatch. + +If storage is unavailable, return a typed `response_budget_exceeded` problem with a narrower request/cursor recommendation. Never emit `compacted_no_handle`, an invalid JSON prefix, or a false complete result. + +### 13.4 Current regression cases + +Fixture-lock: + +- generic Markdown and JSON exceeding the current 15,000-character boundary; +- missing project root/handle cache; +- expired, missing, wrong-project, wrong-profile, wrong-access, and corrupt handles; +- LCM preflight/expand-query compaction tiers; +- multi-block MCP responses so notices do not hide payload/metrics; +- Unicode boundaries and Markdown/code-fence preservation; +- cursor page plus transport retrieval anchor in the same response; +- retrieval after privacy/config/catalog generation change; +- large field omitted while every collection row remains represented. + +## 14. Status, coverage, freshness, missing registry, and partial data + +Every result carries the application envelope. Human renderers always have bounded standard blocks for: + +- resolved scope and active target; +- snapshot/watermark/fetched/indexed times; +- complete/partial/stale/locked/redacted/unavailable coverage; +- exact/estimated/lower-bound/sampled/capped/unknown counts; +- applied limits and next cursor/retrieval anchor; +- warnings and one safe remediation where actionable. + +Rules: + +- “No results” is rendered only when coverage proves the selected universe was searched completely enough to support that statement. +- Missing registry returns empty typed collections plus `registry_state=missing`, not an unrelated error string or absent fields. +- One unavailable shard may produce useful partial success; all unavailable returns a typed problem with per-source coverage. +- A stale graph result cannot be labeled current. Local semantic Git, live delivery state, and joined/reconciled conclusions remain distinct. +- Active state is computed once in the application response and reused everywhere. +- Status commands and MCP status tools consume the shared `SystemStatusSnapshot`; they do not aggregate different component meanings under local booleans. + +## 15. Safe rendering and redaction + +### 15.1 Sink boundary + +Only sealed eligible types enter presentation or machine serializers. Compile-time lints reject public renderer parameters of `String`, bytes, `serde_json::Value`, raw provider records, raw config files, raw paths, or unsanitized errors. + +Before output: + +- authorize fields and payload classes; +- verify sanitization receipt/policy digest; +- apply field-level visibility and redaction state; +- escape Markdown, links, HTML, terminal controls, ANSI, OSC hyperlinks, CSV formulas, JSON/NDJSON line breaks, and logs according to the sink; +- scan generated examples/golden fixtures/docs and encoded output with plan-18 synthetic canaries; +- record counts/classes/rule IDs only, never candidate bytes. + +### 15.2 Output-specific rules + +- Markdown links allow only safe schemes and labels; local file anchors use authorized canonical paths or opaque IDs. +- Terminal output neutralizes control characters and honors `NO_COLOR`/`--no-color` without affecting meaning. +- JSON never interpolates pre-rendered Markdown/ANSI into semantic fields. +- NDJSON guarantees exactly one valid JSON object per line; embedded newlines are encoded. +- CSV escapes RFC-compatible fields and prevents spreadsheet formula execution for exported text. +- errors, labels, aliases, command examples, retry templates, and truncation instructions are safe catalog text. +- secret/credential availability uses typed present/missing/expired/locked state without values, prefix, length, equality fingerprint, URL, or username. + +### 15.3 Redactor configuration surface + +CLI/MCP help and Settings link every privacy/redactor use case to plan 20's canonical config key and effective policy view. Users can inspect and strengthen detector sets, thresholds, actions, structured field rules, retention, quarantine roles, scan schedules, and plugins. The non-disableable floor is visible but never writable. No tool-local `redact=false` or provider bypass exists. + +## 16. Performance, latency, and token budgets + +Every binding declares a `SurfaceBudgetV1`; defaults are reviewed by use-case family rather than copied into handlers. + +Targets on the reference machine: + +- catalog exact binding lookup and generated dispatch: <=100 microseconds p95 excluding use-case execution; +- typed view to Markdown/terminal rendering for a default page: <=2 milliseconds p95 and <=2 MiB transient allocation; +- canonical JSON serialization for a default page: <=2 milliseconds p95; +- CLI parser/help startup after process launch: <=100 milliseconds p95 excluding daemon handshake; +- MCP initialize/version/capability/catalog handshake: <=100 milliseconds p95 with a warm daemon and no selected-store open; one generated list page <=10 milliseconds p95; +- MCP reader/writer/session routing adds <=1 millisecond p95 excluding application execution/rendering; a slow tool cannot block reading cancellation, ping, roots, or client responses; +- default MCP Markdown: <=4,000 estimated tokens soft budget; catalog-declared hard transport cap with cursor/retrieval recovery; +- default discovery result: <=1,000 tokens; one capability detail <=2,000 tokens; +- tool definition descriptions and examples: compact static metadata, with full docs retrieved explicitly rather than loaded into every host prompt; +- default collection pages: normally 20–50 items, hard cap declared per use case; no unbounded `limit`; +- NDJSON/SSE queues: bounded items/bytes and explicit gap/resync behavior; +- MCP per-session requests, server requests, subscriptions, protocol tasks, progress events, and notifications each have reviewed count/byte/deadline caps; list-change/resource-update events coalesce by generation/URI and never form an unbounded queue; +- 1,000 repeated renders of the same typed fixture are byte-stable and leak no state; +- large result rendering scales linearly in returned rows/eligible bytes. + +Benchmarks separately measure application execution, view construction, rendering, serialization, transport framing, truncation/anchor storage, and CLI/MCP overhead. Analytics record safe aggregate latency/bytes/tokens/format/truncation/cursor use by binding ID, never result text. + +## 17. Compatibility, names, aliases, and deletion + +### 17.1 Alias policy + +- aliases are catalog rows with source name, canonical binding, exact semantic equivalence, introduced version, warning policy, cutoff, and docs replacement; +- an alias cannot change scope/default/effect/output or accept fields the canonical binding rejects; +- incompatible semantics get a new binding/use-case major, not an alias; +- old names may be searchable in help after cutoff but are not invokable; +- hidden provider commands are versioned internal bindings, not user aliases; +- bounded warning aliases are a CLI/documentation migration aid only. V2 MCP publishes one current name/schema/protocol epoch; it never accepts an old tool name, argument shape, response-handle envelope, or stale-session fallback after cutover. The plugin/client must upgrade or restart and receives the current binding in a typed incompatibility problem; +- current `query -> search`, `claude-install`, `claude-uninstall`, and `update-plugins` behavior receives explicit disposition; +- `removeall` is normalized with a cutoff rather than kept as permanent naming debt. + +This plan owns the `CompatibilityDisposition` field contract that plan 08 embeds in every `SurfaceBinding` and plan 12 consumes in cutover receipts: + +```rust +pub struct CompatibilityDisposition { + pub action: CompatibilityActionV2, + pub v1_surface: SurfaceKind, + pub v1_names: BTreeSet, // every legacy name/alias/route this row covers + pub replacement: Option, // required for Replace + pub alias_window: Option, // introduced / warn-from / cutoff protocol epochs + pub differential_fixture: FixtureRef, // V1/V2 semantic + presentation differential + pub deletion_receipt: Option, // set once the V1 surface is removed + pub rationale: CatalogSafeText, +} + +pub enum CompatibilityActionV2 { + Keep, // current name is already canonical; no alias window + Rename, // same semantics under a new canonical name; alias_window required + Replace, // superseded by a different use case/binding; replacement required + Remove, // retired with no successor; deletion_receipt required at cutoff +} +``` + +Constraints: exactly one disposition exists per `(v1_surface, legacy name)` inventory row, and every frozen inventory row must reference exactly one; catalog validation rejects `Rename` without `alias_window`, `Replace` without `replacement`, `Remove` without a cutoff `deletion_receipt`, and any two dispositions claiming the same legacy name.

It may prepare context while an agent works, but it never makes a hook wait for a model or invents generic TraceDecay availability text. + +## 1. Contract lock + +1. `IncrementalContextScout` is an application-owned daemon workflow, not a second hint engine, a hook-embedded agent, or an MCP client recursively calling TraceDecay. +2. Canonical capture and projection complete independently of scouting. The scout consumes immutable canonical events and frozen read snapshots; it never becomes an ingest acknowledgement dependency. +3. The synchronous hook path performs no model call, search, graph traversal, remote request, or unbounded read. It only performs a bounded pending-envelope lookup, revalidation, rendering, and delivery within the existing hook budget. +4. No suggestion is the expected result when relevance, authority, freshness, privacy, novelty, timing, or budget is insufficient. +5. A deliverable suggestion is addressed to exactly one `ThreadId`, `TurnId`, `SessionId`, and `AgentId`. Unresolved or ambiguous identity is a suppression reason, never permission to deliver to the current or first session. +6. Every suggestion cites durable `RetrievalAnchorId`s and evidence/provenance. Model prose without anchors, tool receipts, and a pinned input manifest cannot enter a host prompt. +7. Model assistance is optional and capability-selected. A Codex app-server adapter may use a low-latency model such as Spark when the app server advertises it and configuration selects it; no model name, provider, executable, or fallback is hardcoded in domain or application code. +8. The model proposes bounded structured exploration and candidate semantics. The application authorizes and executes tools; pure policy ranks, deduplicates, suppresses, budgets, and selects; the hooks crate renders and delivers. The model cannot call arbitrary shell, MCP, network, filesystem, mutation, or curation operations. +9. Read-only is the default and V2 launch maximum effect class. Local query/search/memory/LCM/code/Git/coordination reads are eligible only through cataloged application use cases. Remote read/egress requires an explicit grant and remains separately labeled. +10. Suggestions are compact, specific, and non-overbearing. Static capability boilerplate, repeated categories, restated user prompts, vague advice, and uncited generated claims are invalid output. +11. Late, stale, expired, superseded, redacted, or already-observed suggestions are recorded with a disposition and never silently injected into a later logical message. +12. The scout shares the canonical hint state (plan 6's `HintStateSnapshot`, fields in [06-policy-crate.md](./06-policy-crate.md) §9.1.2), policy, catalog, configuration, presentation, delivery receipt, and outcome pipeline. It does not create parallel counters, renderers, model settings, or dashboard-only state. +13. Replay, shadow, A/B evaluation, and “what would happen now?” are read-only. They never deliver, mutate counters, affect dedupe, or create per-item approval/apply/rollback flows. +14. Existing deterministic hint classifiers remain a candidate source during migration, then move behind the same policy contract. There is one delivery selector at cutover: plan 6's `DeliveryArbiterV1` ([06-policy-crate.md](./06-policy-crate.md) §9.1.3), which arbitrates deterministic and scout `DeliveryCandidateV1` submissions under one `HintStateSnapshot` version compare-and-swap. +15. Canonical initiative/task/ticket/dependency/claim/context-packet events are eligible evidence, not a broadcast feed. A sibling-task change reaches an exact Thread/Turn only when evidence proves material overlap, a blocker, a handoff, or an invalidated assumption. + +This plan extends the contracts in [01-domain-crate.md](./01-domain-crate.md), [06-policy-crate.md](./06-policy-crate.md), [07-hooks-crate.md](./07-hooks-crate.md), and [09-application-crate.md](./09-application-crate.md). Configuration is exclusively owned by [20-configuration-control-plane.md](./20-configuration-control-plane.md); plan 09 owns semantic response views while capability, binding, rendering, and format parity are exclusively owned by [21-cli-mcp-tool-surface-and-output-unification.md](./21-cli-mcp-tool-surface-and-output-unification.md); every message/LCM/context read and current/as-of decision is owned by [23-session-lcm-temporal-retrieval-and-evaluation.md](./23-session-lcm-temporal-retrieval-and-evaluation.md) through the sole `TraceQueryV1` path; canonical task refs/events are owned by [24-canonical-task-plan-graph-and-multi-agent-executor.md](./24-canonical-task-plan-graph-and-multi-agent-executor.md). + +## 2.

As events accumulate during a Turn, the daemon incrementally asks a bounded question: “Is there one new, well-supported piece of context that would materially improve the next safe action?” It may: + +- recover a directly relevant prior Turn, memory, fact, LCM summary, or research anchor; +- find a code symbol, call/impact path, diagnostic, Git change, branch, worktree, PR, or delivery fact that resolves the current uncertainty; +- notice a nearby agent or parallel worktree already doing materially overlapping work; +- connect the exact current task to a cross-repository initiative, dependency, sibling-task claim, blocker, handoff, or newly published context packet; +- connect the current Turn to parent/subagent/session/workflow/goal evidence; +- identify that the semantic index, scope resolution, or live/local Git join is stale or incomplete and propose one exact recovery action; +- recommend one cataloged TraceDecay capability when its use has high expected value and has not already been used; +- prepare an authorized retrieval bundle before the next provider injection boundary. + +The result is a compact typed envelope with exact addressee, expiry, evidence, retrieval anchors, reason, and delivery policy. A custom suggestion may be model-assisted, but its truth comes from authorized evidence and receipts rather than model confidence alone. + +### 2.2 Non-goals + +- No autonomous edit, commit, branch, PR, message, curation, schedule, configuration, or external-system mutation. +- No second general-purpose agent runtime or unrestricted tool loop. +- No attempt to inject continuously while a host has no supported steering boundary. +- No replacement for host compaction, memory curation, search, or the deterministic policy engine. +- No inference that temporal adjacency proves causation, adoption, or agent ownership. +- No raw transcript mirror, secret-bearing prompt cache, or model-output search index. +- No global “helpfulness” stream. A suggestion must be materially related to the exact current Turn. +- No manual queue where operators approve, apply, reject, or roll back individual scout results. +- No requirement that an app server, Spark, a network, or any model is available. Deterministic-only and fully disabled modes are first-class. + +## 3. Canonical ownership and dependency DAG + +Do not create a new crate. Scouting has one deployment consumer, and its invariants already belong to domain, store, query, policy, hooks, catalog, application, API, and root composition.

Self-generated event exclusion is based on producer/correlation IDs, not fragile name prefixes. + +### 5.2 Coalescing and cancellation + +Partition state by `(ProfileId, ThreadId, AgentId)` and serialize scheduling per partition while allowing profile-wide bounded concurrency. + +1. Append every canonical event normally. +2. Record its scout eligibility/disposition without blocking the originating outbox consumer. +3. Coalesce eligible events for the same Turn over a configurable 75–300 ms quiet window, capped by a 750 ms maximum wait. +4. Merge only rebuildable trigger summaries; retain all source event IDs in the run manifest. +5. A newer user message, scope generation, Turn closure, or access/config/policy generation invalidates an older queued run. +6. Cancel active model/tool work at declared boundaries. A cancellation cannot retract a delivered envelope; it may supersede only pending envelopes. +7. Maintain at most one active run plus one coalesced queued generation per address. +8. Fair scheduling uses per-profile, project, worktree, and agent token buckets so one noisy agent cannot starve others. + +Cancellation checks occur before snapshot acquisition, before and after every model request, before each tool execution, every query page, before policy evaluation, before persistence, and before delivery claim. + +### 5.3 Backpressure + +| Tier | Condition | Behavior | +|---|---|---| +| 0 normal | queue/age/cost below targets | deterministic plus configured model path | +| 1 coalesce | transient burst | extend within max debounce; collapse rebuildable triggers by address | +| 2 supersede | old runs behind current Turn | cancel obsolete generations; record `Superseded` | +| 3 deterministic-only | model queue, provider, or cost pressure | skip model; evaluate deterministic candidates only | +| 4 optional-work shed | disk/CPU/store/query pressure | record `Overloaded`; remain silent; preserve canonical capture | +| 5 paused/circuit-open | operator/config/health decision | advance examined checkpoint with explicit paused disposition; no scouting | + +The scout must never retain an outbox transaction or writer lock while waiting.

Historical runs remain evidence and acquire supersession links. +- A large lag is not replayed as current advice. Catch-up records historical eligibility for evaluation, expires old envelopes without model work, and begins live scouting at a declared watermark. +- Checkpoint corruption isolates the scout consumer; it does not block capture/projectors.

Pure ranking, relevance, and silence policy + +`tracedecay-policy/src/scout.rs` (`EvaluatorKind::Scout`, reserved in plan 6's module tree and evaluator registry) consumes only the pinned input manifest, candidates, receipts, prior hint state, configuration values, and an explicit clock. It returns a `ScoutDecisionV1` with selected envelope proposal or silence plus reason codes, following plan 6's evaluator patterns (registered input/output schemas, fixed-point scores, decision/explanation digests): + +```rust +pub struct ScoutDecisionV1 { + pub run_id: ScoutRunId, + pub evaluation_id: PolicyEvaluationId, + pub input_manifest_id: ManifestId, + pub scored: Vec, // plan 6 shape; one entry per SuggestionCandidateV1 + pub selected: Option, + pub envelope_proposal: Option, // Pending state; unpersisted until the CAS commits + pub suppressions: Vec<(SuggestionCandidateId, SuggestionSuppressionReasonV1)>, + pub silence: Option, + pub state_proposal: HintStateProposal, // plan 6 §9.1.2; the single CAS on the hint-state version + pub explanation: DecisionExplanation, + pub decision_digest: ManifestDigest, +} +``` + +Fixed-point feature groups: + +| Group | Positive evidence | Penalties/abstention | +|---|---|---| +| relevance | exact current goal/intent/entity/tool/error/symbol match | broad topical similarity only | +| evidence | direct/provider/derived facts; complete scope; fresh anchor | heuristic-only, partial, stale, ambiguous | +| expected value | resolves blocker, prevents duplicated work, recovers missing context | advice agent already followed | +| novelty | unseen anchor/relationship/capability for this logical message | repeated category, payload, anchor, or work claim | +| urgency | useful before next tool/edit/compaction boundary | useful only after Turn closes | +| specificity | exact retrieval, symbol, session, agent, branch, or recovery action | generic “consider searching” text | +| cost | low tokens/latency/tool/model cost | budget pressure or uncertain value | +| privacy | fully authorized and sanitizer-current | redacted/locked/unknown/egress mismatch | + +Policy ordering: + +1. validate exact identity, scope, access, snapshot, time, and host capability; +2. remove stale, expired, unauthorized, unanchored, already-observed, and generic candidates; +3. compute logical-message, semantic, category, anchor, and coordination-pair fingerprints; +4. apply dedupe, cooldown, escalation, turn/session/global budgets, and quiet-mode thresholds; +5. compare top candidate against the explicit silence utility; +6. render at most one envelope with no more than three anchors; +7. propose one atomic hint-state transition and envelope write. + +Default presentation budget is 96 tokens; hard maximum is 160. Default delivery is at most one scout suggestion per Turn, four per session, one initial category plus one later evidence-strengthened escalation, and one coordination advisory per unchanged claim pair. Configuration may be stricter. Safety and compactness floors prevent looser values beyond hard caps. The turn/session/token budgets here are the shared plan 6 `HintStateSnapshot` ledgers debited by `DeliveryArbiterV1` for both engines; the four-per-session scout quota is the dedicated scout session ledger inside that same snapshot, not a parallel counter. + +Semantic fingerprint inputs are category, intent, exact address/logical message, resolved scope digest, primary entity/anchor set, proposed capability, and normalized bounded payload meaning. Every output is a plan-01 `PrivacyDomainKeyedFingerprintV1` bound to the address privacy domain and active key epoch; it is never a generic/public content digest, and key rotation rebuilds or safely forgets state rather than comparing epochs. Model wording changes alone cannot evade dedupe. + +## 10. Many agents, worktrees, repositories, and projects + +Scouting uses the exact scope and temporal attribution contracts in [16-cross-project-repository-worktree-scope.md](./16-cross-project-repository-worktree-scope.md). + +- Repository, project, checkout, worktree, ref, commit, `CodeSnapshotId`, graph generation, and index watermark remain distinct. +- Same repository or path basename does not imply same worktree, ref, snapshot, or task. +- Parent/subagent, sibling-agent, handoff, goal, and work-claim relations require captured/provider evidence. +- Nearby work uses authorized `AgentPresenceV1`, `WorkClaimV1`, TTL, evidence-bearing overlap, and a `CatalogSafeText` summary. It never passes another agent's raw prompt or reasoning. +- Cross-worktree code/Git reads name both source and target immutable snapshots; live PR/delivery state remains separately fresh and joined. +- Cross-project expansion is allowed only when the run's declared scope permits the immutable project-set version. A model cannot turn `Current` into `AllAuthorized`. +- Scheduler fairness is keyed by profile/project/worktree/agent while delivery dedupe is keyed by exact addressee. One agent's receipt never marks another agent as having seen a suggestion. +- Planned redundant ensemble work is suppressed as a duplicate-work warning; diversity/review roles are not treated as accidental overlap. +- When overlapping agents are found, the envelope gives one safe summary plus retrieval anchors to agent/work-claim/session context. It does not auto-message, cancel, lock, or reassign either agent. +- When coverage cannot prove proximity, remain silent and expose the coverage gap in Observatory, not in the model prompt. + +The Rspack/Rsbuild/React Router scenario pack from plan 16 must include sibling worktrees, same basename, copied subagent prompts, planned duplicate benchmarking, accidental duplicate research, and live/local PR drift. + +### 10.1 Canonical task/ticket graph integration + +[`24-canonical-task-plan-graph-and-multi-agent-executor.md`](./24-canonical-task-plan-graph-and-multi-agent-executor.md) owns `InitiativeId`, `WorkItemId`, `WorkItemVersionId`, task/ticket presentation aliases, dependency predicates, task claims, context packets, and their repository/project/worktree/agent/Thread relations. The scout consumes its immutable events and application reads; it does not create a private task table or infer canonical tickets from prompt text. + +One initiative may span Rspack, Rsbuild, plugins, and React Router repositories while Codex, Claude, Cursor, or other agents own sibling tasks in separate worktrees. A task event is deliverable context only after a bounded relevance join establishes one of: + +- the current `WorkItemId` directly depends on, blocks, supersedes, duplicates, or shares a declared deliverable with the changed sibling work item; +- both task claims cover the same repository/ref/file/symbol/test/PR/retrieval anchor with material overlap above policy threshold; +- a sibling task changed an assumption explicitly referenced by the current task/context packet; +- a blocker was added, cleared, or reassigned on the current dependency path; +- a handoff names the current agent/task/Thread or transfers an evidence packet required by it; +- a new context packet contains authorized anchors selected for this task or resolves a recorded evidence gap; +- a sibling outcome invalidates a pinned code/Git/API/config/version fact used by the current Turn. + +Project membership, common initiative membership, chronological proximity, shared labels, same repository, or “nearby” work alone are insufficient. The scout never streams a global board, sprint activity, ticket comments, or all sibling progress into prompts. + +```rust +pub struct MaterialTaskChangeV1 { + pub current_task: WorkItemVersionRefV1, + pub changed_task: WorkItemVersionRefV1, + pub relation: TaskRelevanceKindV1, + pub dependency_path: Vec, + pub current_claim: Option, + pub sibling_claim: Option, + pub context_packets: Vec, + pub retrieval_anchor_ids: Vec, + pub materiality: ScoreMicros, + pub coverage: CoverageReportV1, + pub watermark: VectorWatermark, + pub expires_at: UtcMicros, +} + +pub enum TaskRelevanceKindV1 { + DirectDependencyChanged, + BlockerChanged, + MaterialClaimOverlap, + HandoffToCurrentWork, + ContextPacketForCurrentWork, + AssumptionInvalidated, + DeliverableSuperseded, +} +``` + +Delivery still targets the exact `SuggestionAddressV1`, not a task, initiative, project, or agent type. The envelope states the changed task, its material relation to current work, one safe consequence or retrieval idea, and task/claim/context-packet anchors. It does not dump ticket bodies or another agent's reasoning. + +Task notification fingerprints include current/changed `WorkItemId`, relation kind, dependency/claim version, primary anchors, current logical message, and target address. Unchanged versions suppress; a stronger blocker or new invalidating evidence may produce one evidence-strengthened escalation. Pair/category cooldown and per-Turn/session budgets apply across providers so duplicate Codex/Claude capture cannot produce repeated notices. + +Authorization is evaluated independently for the current task, sibling task, claim, packet, repository, and target agent. If only the existence of a sibling change is visible, the scout does not leak its title, summary, owner, repository, or anchors. It either emits an authorized generic relation code with one legal retrieval action when materially useful, or remains silent. Global task-board visibility never implies prompt-delivery authority. + +## 11. Delivery handshake and timing + +The daemon and each host adapter negotiate a versioned capability session: + +```rust +pub struct SuggestionHostHelloV1 { + pub host: HostKind, + pub host_version: ComponentVersion, + pub source_instance_id: SourceInstanceId, + pub supported_modes: BTreeSet, + pub supported_hook_points: BTreeSet, + pub max_payload_tokens: u32, + pub max_payload_bytes: u32, + pub protocol_version: SchemaVersion, +} + +pub enum SuggestionDeliveryModeV1 { + NextPromptContext, + PreToolContext, + ProviderSteer, + NotificationOnly, +} + +pub struct PendingSuggestionRequestV1 { + pub invocation_id: HookInvocationId, + pub address: SuggestionAddressV1, + pub hook_point: HookPoint, + pub last_seen_sequence: u64, + pub remaining_budget: Duration, + pub access_policy_digest: AccessPolicyDigest, +} +``` + +`HookApplicationPort` gains a narrow `claim_pending_suggestion` operation. The claim is a `DeliveryArbiterV1` operation ([06-policy-crate.md](./06-policy-crate.md) §9.1.3), not a parallel scout-side CAS: one transactional compare-and-swap on the `HintStateSnapshot` version token that revalidates address, logical message, scope/access digest, expiry, current hint state, payload budget, host mode, and envelope sequence, and claims the pending-suggestion slot. Deterministic candidates arbitrated in the same invocation ride the same version token, so at most one engine delivers. It performs no query or model work. + +Timing rules: + +- ready before `PromptSubmit`: inject through the provider's supported developer/additional-context field, never by wrapping a normal prompt in a fake `UserPromptSubmit hook (completed)` user message; +- ready after prompt submission but before a declared `PreToolUse` boundary: deliver only if the category remains relevant to that exact Turn and the host supports that context field; +- ready mid-generation: use `ProviderSteer` only when explicitly advertised, semantically safe, and the envelope is urgent enough under policy; otherwise do not interrupt; +- ready after the useful boundary: mark `Late`, optionally reconsider as a new candidate against the next Turn only when the underlying evidence is independently relevant and a new envelope/address is created; +- `NotificationOnly` is dashboard/host-visible status, not presumed model context; +- no supported mode: suppress with `HostCannotDeliverSafely`; +- timeout or store contention: return no suggestion and preserve the existing hook response. + +Delivery adds no wait for an active run. Target budget: pending lookup/revalidation p95 <=2 ms, p99 <=5 ms, and zero model/network/tool latency on the hook critical path. Existing plan 7 total deadlines remain authoritative. + +Claim and delivery are separate: + +1. application atomically claims envelope with invocation/lease and returns exact bytes/digest; +2. host adapter renders and attempts delivery; +3. adapter records delivered, failed, rejected, or unknown receipt; +4. claim timeout returns envelope to eligible only if no host acknowledgement could have occurred; uncertain delivery is never retried automatically; +5. retries by the same invocation return the stored receipt while its policy/catalog/environment digest still matches and do not duplicate injection; a digest mismatch returns a typed stale-environment error rather than re-evaluating or redelivering (the plan 7 §8 retry rule). + +## 12. Feedback and outcome attribution + +The lifecycle is: + +```text +trigger -> run -> reads -> candidates -> policy/silence -> envelope + -> claim -> host delivery -> observed action/retrieval/feedback + -> terminal outcome with evidence and coverage +``` + +Outcomes extend the shared plan 6/7 hint contract through plan 6's recorded outcome enum v2 revision ([06-policy-crate.md](./06-policy-crate.md) §10 — the only legal extension path for those closed enums) and persist as plan 6 `HintOutcomeRecordV1` rows: + +- `Observed`: directly linked retrieval-anchor open, suggested capability invocation, scope recovery, handoff/coordination action, or accepted host acknowledgement plus corroborating action; +- `Unobserved`: horizon closed with adequate capture coverage but no linked action; not automatically “bad”; +- `Unresolvable`: capture gap, ambiguous causation, missing provider event, delivery unknown, or horizon loss; +- `HumanHelpful`, `HumanNotHelpful`, `HumanIncorrect`, `HumanTooLate`, `HumanRepeated`, and `HumanTooVerbose` are explicit feedback evidence, not silent model training labels; +- `PreventedDuplicateWork` requires evidence that a work claim, handoff, or task changed after delivery; temporal proximity alone is insufficient; +- correction records the corrected intent/scope/entity/route and exact suggestion ID; +- dismissal/mute affects future policy state at the declared scope but never deletes historical evidence. + +Every numerator has an eligible denominator, terminal horizon, coverage threshold, and delivery-state exclusion.

It cannot claim/deliver an envelope, mutate live hint state, invoke mutation tools, or approve/apply/rollback curation.

Move deterministic `tool_hints` classifier outputs behind pure plan 6 policy as the `DeliveryCandidateV1::Deterministic(ScoredCandidate)` arm of `DeliveryArbiterV1` without changing delivery; scout candidates enter the same union as `DeliveryCandidateV1::Scout(SuggestionCandidateV1)`. +4. Implement the scout worker in shadow against canonical outbox events. It writes runs/candidates/suppression but no deliverable envelope. +5. Add provider-neutral model gateway and Codex app-server adapter behind capability/config selection. Do not reuse automation config or `TRACEDECAY_CODEX_SUMMARY_*` as scout defaults. +6. Run frozen/offline and rolling shadow evaluation; fix logical-message origin, scope, privacy, latency, and dedupe regressions. +7. Add durable envelopes and host handshake. Differential-test render bytes/state receipts while keeping V1 as sole delivery owner. +8. Enable V2 deterministic delivery for one host/scope; enforce plan 6's `DeliveryArbiterV1` as the single delivery selector and compare outcome denominators. +9. Enable optional model-assisted delivery only for eligible strata that pass gates. +10. Migrate CLI/MCP/API/UI to generated use cases and typed views; preserve bounded aliases only where plan 21 requires them. +11. Backfill historical scout-evaluation evidence for labs only.

What current search actually does + +This is a source audit, not a critique based on names or documentation. + +### 1.1 `message_search` + +Current anchors: + +- `src/global_db.rs:626-676` defines a maximum pre-rerank fetch of 200, inventory downranking, and `session_fts_query`. +- `src/global_db.rs:4216-4400` executes the message search. +- `src/global_db.rs:1100-1145` defines `session_messages` and `session_messages_fts`. +- `src/mcp/tools/handlers/session.rs:396-590` parses filters, merges registered-project results, and builds output. +- `src/mcp/tools/handlers/session.rs:2353-2558` performs catch-up, registered-project fan-out, and selected-project routing. + +Observed semantics: + +1. Every whitespace token becomes a quoted prefix expression and tokens are joined with `OR`, not `AND`. A long conceptual query can match a row containing only one generic token. +2. FTS5 indexes `text`, `role`, `kind`, `model`, and `tool_names`. BM25 weights are `10, 2, 1, 1, 1`; the result score is the negated BM25 rank. +3. There is no temporal feature or current-state resolver. Timestamp is a tie-break only in the all-registered merge; single-shard search preserves BM25 order after inventory downrank. +4. There is no explicit authority, evidence, correction, supersession, contradiction, branch-state, or validity feature. +5. Hyphenated query terms add an exact lowercase substring predicate; other punctuation and phrase semantics are limited. +6. Provider, provider-level `project_key`, registered project, parent/subagent relation, message type, time range, Git branch/worktree/commit, and workflow run/agent are filters. +7. Search catches up provider transcripts by default. A nominal read can therefore perform ingestion unless `catch_up:false` is explicit. +8. Inventory/listing text is downranked after a 4x over-fetch. Related copies are deduplicated only when provider, parent/child family, and normalized content align; repeated rows inside a session and copies across unrelated/missing-link sessions, providers, or project shards remain. +9. `project_scope:all_registered` asks each shard for its local top K, then compares raw BM25 scores across independent corpora. Those scores are not calibrated across shard document frequencies, so “exact distributed top K” is not justified by matching sort keys alone. +10. Results contain full session/message records in JSON and a score without component explanation. They do not contain a durable V2 retrieval anchor, cluster identity, current/stale state, source coverage, or next cursor. +11. Limits clamp to 1–50. All-registered search reports searched/skipped project counts, but not a per-shard coverage/disposition ledger in the compact human result. +12. JSON output can exceed the global response limit and becomes an expiring response-handle envelope; Markdown is compact but still lacks paginated continuation and stable result hydration. + +### 1.2 `lcm_grep` + +Current anchors: + +- `src/sessions/lcm/schema.rs:13-78` defines raw content-only FTS. +- `src/sessions/lcm/schema.rs:220-245` defines summary-node FTS over summary text, expand hints, and metadata. +- `src/sessions/lcm/query.rs:380-500` combines raw and summary candidates and applies inventory/session caps. +- `src/sessions/lcm/query.rs:1700-1955` executes raw and summary FTS/LIKE paths. +- `src/sessions/lcm/query.rs:3494-3542` defines relevance, hybrid, and recency order. + +Observed semantics: + +1. Raw LCM FTS is content-only. Role/source/time/relationship/Git filters are SQL predicates. +2. The default is relevance: BM25 rank first, user before assistant before tool as a tie feature, and recency after that. +3. Hybrid divides the negative BM25 rank by an age denominator using a fixed `0.001` per-hour decay. Recency is an explicit separate sort. +4. Raw and summary candidates are not calibrated in one candidate pool. Raw hits are fetched first; summaries are appended only if raw hits leave budget. For relevance/hybrid the later Rust sort does not compare raw and summary scores. +5. Scope `all` caps each session at three hits and reserves a tool-action slot when narration otherwise fills the cap. The response reports capped sessions. +6. Summary results disappear when raw-only filters such as role, time, or message type are active, because summary projections cannot prove those fields directly. +7. CJK, emoji, risky punctuation, and malformed quote shapes take a LIKE fallback with different ranking properties. +8. Parent/child copy dedup has the same bounded family/content rule as message search. Summary-source duplicates and copies across shards/providers remain separate. +9. Maximum page size is 100; there is no federated all-registered LCM search or stable cross-project discovery-to-load route. + +### 1.3 `lcm_expand_query` and replay + +Current anchors: + +- `src/sessions/lcm/query.rs:647-795` assembles expand-query context. +- `src/sessions/lcm/types.rs:371-430` defines the request/response. +- `src/mcp/tools/handlers/session.rs:1-50` defines current content/prompt/result caps. + +Observed semantics: + +1. The request requires one provider and one provider-local session ID. It cannot start from a cross-project search result without the caller manually routing to the correct store. +2. Query selection is session-scoped and hard-coded to recency. +3. Summary candidates are selected before raw candidates. A summary can consume the result/context budget before the exact source message is considered. +4. Explicit `node_ids` bypass query selection and expand summary nodes directly. +5. `context_max_tokens` is currently used as a character budget (`context_max_chars`), so naming and accounting are not semantically exact. +6. The response exposes context truncation/pagination, but synthesis availability changes whether the host receives an answer or raw context. +7. No-match is a successful answer string, not a calibrated distinction among “no relevant evidence,” “wrong shard,” “not ingested,” “retained/locked,” “summary horizon missing,” or “query too narrow.” +8. Session replay returns head, tail, and deepest/recent summary nodes, but does not choose query-relevant Turns, correction chains, Git/code impacts, or adjacent agent/workflow evidence. + +### 1.4 Current evaluation coverage + +`tests/fixtures/message_search_eval_labeled.json` contains 12 synthetic queries: 10 positive and 2 negative. The live test recomputes Precision@1, Precision@3, and MRR. It covers branch-inventory downrank, relevance-over-recency for a rare synthetic term, provider/project filtering, assistant-versus-tool noise, multi-term coverage, case-insensitive prefix match, exact single hit, and absent/hyphen negatives. + +That fixture is useful but insufficient: + +- all positive queries currently have one desired first result or a tiny synthetic set; +- the corpus has no real corrections, supersession chain, current-versus-historical query, logical copy cluster across shards, stale summary horizon, cross-project routing, partial shard, semantic paraphrase, user-prompt recall, subagent duplication, or result-budget failure; +- it does not grade relevance 0–3, nDCG, Recall@K, calibration, duplicate rate, temporal accuracy, privacy, latency, tokens, cost, or per-project/provider strata; +- known live probes in Plan 15 are discovery evidence, not frozen qrels. + +No production-default embedding or dense message-search channel was found in this audit. V2 must evaluate optional local semantic channels; it must not describe current lexical/LIKE behavior as semantic retrieval. + +## 2.

The receiving occurrence remains addressable and carries its own session/Turn/audience context. +- A provider-native ID collision across source instances is conflict evidence, not an `INSERT OR REPLACE` instruction. +- Occurrence storage — uniqueness over `(source_instance_id, source_observation_id, source_order)`, keys, and indexes — is defined by plan [`02-store-crate.md`](02-store-crate.md)'s occurrence table family; this plan owns only the semantics above. + +### 3.2 Logical clusters are versioned assertions + +```rust +pub struct LogicalMessageClusterV1 { + pub cluster_id: LogicalMessageClusterId, + pub revision: ClusterRevision, + pub member_occurrences: NonEmpty, + pub relations: Vec, + pub representative_policy_version: RepresentativePolicyVersion, + pub projection_watermark: VectorWatermark, +} + +pub struct MessageCopyAssertionV1 { + pub assertion_id: MessageCopyAssertionId, + pub subject: MessageOccurrenceId, + pub object: MessageOccurrenceId, + pub relation: MessageCopyRelation, + pub evidence: Vec, + pub confidence: Confidence, + pub valid_time: TimeInterval, + pub transaction_time: TimeInterval, +} +``` + +`MessageCopyRelation` includes `same_provider_event`, `forwarded_prompt`, `parent_child_copy`, `workflow_delegation_copy`, `compaction_replay_copy`, `store_replica_copy`, `summary_quotes_source`, and `possible_duplicate`. Only high-confidence identity relations share a logical representative. `possible_duplicate` is a ranking/diversity hint and never destroys independent evidence. + +Cluster revisions are retained and queryable by transaction time: plan 02's cluster table family keeps prior revisions, so as-of replay of cluster-dependent features (copy-noise penalty, representative selection) reads the revision current at the knowledge-time cutoff rather than today's clustering. + +Representative selection is query-dependent: + +- direct human origin for user-intent recall; +- source occurrence for forensic replay; +- current parent Turn for active-thread navigation; +- tool event for “what command changed this?”; +- summary node for an explicit overview request; +- highest-authority current assertion for current-state recall. + +The result returns the chosen representative, every hidden-member count by provider/session/project, and a stable expansion anchor. + +### 3.3 Turns and threads are first-class retrieval grains + +A `Turn` groups one initiating event, assistant/reasoning parts, tool invocations/results, edits, goals, spawned agents, handoffs, and terminal outcome under provider-declared or evidence-backed boundaries. It is not inferred only from alternating roles. + +A `Thread` can span provider sessions, compaction continuations, resumed hosts, and handoffs. `thread_sessions` records relation/evidence/time rather than copying all messages into one session. Retrieval can return: + +- exact message; +- smallest sufficient Turn; +- session episode; +- thread evolution; +- agent/workflow slice; +- evidence bundle crossing Git/code/PR relations. + +The query result always states which grain was ranked and which source anchors will be hydrated. + +## 4. Temporal truth, correction, and supersession + +### 4.1 Assertions, not overwritten facts + +Messages can contain claims, decisions, preferences, plans, status observations, commands, or hypotheses. Projectors may extract **assertion candidates** but cannot silently promote model inference to truth. + +```rust +pub struct TemporalAssertionV1 { + pub assertion_id: TemporalAssertionId, + pub subject: EntityRef, + pub predicate: PredicateId, + pub object: AssertionValue, + pub scope: DeclaredScope, + pub valid_time: TimeInterval, + pub transaction_time: TimeInterval, + pub status: AssertionStatus, + pub authority: AuthorityClass, + pub evidence: NonEmpty, + pub confidence: Confidence, +} + +pub struct AssertionRelationV1 { + pub relation_id: AssertionRelationId, + pub predecessor: TemporalAssertionId, + pub successor: TemporalAssertionId, + pub kind: AssertionRelationKind, + pub evidence: NonEmpty, + pub confidence: Confidence, + pub decided_by: DecisionProvenance, +} +``` + +`AssertionRelationKind` includes `replaces`, `corrects`, `contradicts`, `refines`, `narrows_scope`, `extends_validity`, `revokes`, `reaffirms`, and `independent`. `AssertionStatus` includes `candidate`, `supported`, `current`, `superseded`, `revoked`, `conflicted`, and `unknown`. + +### 4.2 Authority and evidence are typed + +Authority is contextual and predicate-specific: + +- a direct later human correction is stronger for user intent than an older assistant summary; +- an actual Git ref/check/merge observation is stronger for current repository state than chat narration; +- a committed command receipt is stronger for “what changed?” than a proposed plan; +- provider-native parent/child metadata is stronger for agent lineage than copied prompt text; +- a summary is useful navigation but not stronger source evidence than the messages it summarizes; +- an explicit “hypothesis” does not become a decision because it is recent; +- a stale high-authority decision can remain historically decisive while no longer current. + +Authority never crosses scope automatically. A decision for one repository/worktree/branch cannot supersede a similarly worded decision for another. + +### 4.3 Answer modes + +Answer modes ride the optional `temporal` clause of `TraceQueryV1`. Plan [`01-domain-crate.md`](01-domain-crate.md) owns the exact clause type (`TemporalClauseV1::Current | AsOf{valid_time, knowledge_time} | Evolution | Forensic`); plan [`05-query-crate.md`](05-query-crate.md) §6/§11.4 plans and executes it. Evolution bounds, when requested, are expressed only through `TraceQueryV1.time`; the mode never gains a second `from`/`to` field. This plan defines no parallel `TemporalAnswerMode` AST — it supplies the mode semantics: + +- `Current`: prefer assertions valid now at the frozen snapshot; collapse confident supersession chains to the current representative, but return a history/conflict warning and lineage anchors. +- `AsOf { valid_time, knowledge_time }`: evaluate only evidence valid at `valid_time` and known by `knowledge_time`; both timestamps are required per 05 §11.4 — a single-timestamp as-of conflates validity with knowledge and is rejected at validation. This mode supersedes this plan's earlier single-timestamp `Historical` mode. Never leak later corrections into ranking features or summaries. +- `Evolution`: rank change points and relation chains, not one winning document. +- `Forensic`: preserve occurrences and weak/contradictory evidence with minimal dedup; useful for audits and implementation archaeology. + +Query intent can choose a mode only when confidence is high. Ambiguous queries return the current answer plus a compact “historical/conflicting evidence exists” section, or expose an explicit mode selector. They do not silently hide either side. + +### 4.4 Recency is bounded and explained + +Recency may affect: + +- current-state queries after validity/authority constraints; +- active-agent/worktree proximity; +- recent session listings; +- ties among equivalent evidence; +- stale-summary risk; +- context budget selection for an active Turn. + +Recency must not: + +- override an explicit correction graph in the wrong direction; +- make a newer tool/schema echo outrank the original user request; +- turn ingestion delay into event recency; +- compare provider timestamps from incompatible clock domains without normalization/uncertainty; +- use store row IDs as cross-shard time; +- boost repeatedly retrieved stale evidence until it becomes self-reinforcing truth. + +Every time feature states its source (`occurred`, `observed`, `ingested`, `valid_from`, `valid_to`, `source_order`) and uncertainty. + +## 5. Query intent and retrieval plan + +### 5.1 Intent classes + +The session-retrieval intent profile rides `TraceQueryV1` unchanged: temporal mode and cutoff use the first-class optional `temporal` clause (§4.3; plan 01 owns `TemporalClauseV1`), and intent profile, grain, origin/audience/kind, provider, evidence-relation, assertion-status, and summary-freshness filters use the registered attribute keys specified in plan 05 §6.1. No parallel AST, fork, or session-only query type exists. The versioned, inspectable intent classes are: + +- `exact_literal_or_identifier` — errors, paths, API/tool/config names, session/message/Turn IDs, branch/commit/PR identifiers; +- `original_user_request` — direct human prompt or correction, not copied child prompts/tool results; +- `decision_or_preference_current` — current authoritative assertion and its lineage; +- `decision_or_preference_as_of` — state at a declared historical cutoff; +- `evolution_or_why_changed` — correction/supersession/decision chain; +- `session_or_thread_recovery` — smallest sufficient Turn/session plus adjacent context; +- `agent_or_workflow_activity` — goal, work claim, spawned agents, tool/edit effects, handoff, outcome; +- `git_code_delivery_correlation` — sessions/Turns that proposed, produced, observed, reviewed, or were affected by a Git/code/PR artifact; +- `cross_project_causal_context` — federated evidence across resolved repositories/worktrees; +- `tool_history_or_debugging` — tool definitions/calls/results are intentional rather than noise; +- `thematic_exploration` — diverse broad results with lower current-state assumptions; +- `no_answer_validation` — caller wants proof of absence/coverage rather than nearest topical text. + +The plan records intent probabilities, selected profile, original query, exact protected literals, aliases/entities, scope, temporal mode, budgets, and fallback policy. A caller can override mode/scope/grain without hand-authoring rank weights. + +### 5.2 Candidate channels + +Candidate generation is independently bounded and ablatable: + +1. exact canonical/native/retrieval ID and exact phrase; +2. fielded lexical BM25 over typed origin, role, kind, entity, tool, Git, code, goal, and content fields; +3. character n-gram/edit-distance fuzzy channel for misspellings and partial identifiers; +4. entity/alias channel for projects, repositories, worktrees, refs, PRs, sessions, agents, tools, symbols, and facts; +5. temporal assertion/current-state index; +6. relation graph seeds and bounded typed expansion; +7. summary-DAG documents with source horizon/coverage; +8. optional privacy-domain local dense retrieval; +9. optional learned-sparse retrieval; +10. optional bounded local reranker — a post-fusion stage executed by plan 05's `rank/rerank.rs` (15 §4.4), listed here for ablation completeness rather than as a candidate channel; +11. explicit recent-activity listing channel for listing intent only — the `list_sessions`/`list_messages` list intents defined in plan 05 §6.2. + +Each candidate carries channel rank, native score, normalized/calibrated score if available, matched fields/terms/entities, owner shard, index/profile/model versions, source/summary horizon, privacy eligibility, watermark, cap/truncation, and latency. + +### 5.3 Federated scoring + +Never compare raw shard BM25 scores as if corpus statistics were shared. Evaluate these baselines: + +- rank-based reciprocal-rank fusion across owner shards; +- globally versioned field/document-frequency statistics with bounded staleness disclosure; +- per-shard score calibration trained only on frozen development judgments; +- exact-match tiers before any score normalization; +- two-stage global candidate fusion and local hydration. + +The selected method must prove byte-stable results for a fixed shard layout and bounded, explained drift when the same logical corpus is repartitioned. Exact-match tiers remain invariant; other top-k changes must satisfy the locked overlap/nDCG and worst-stratum floors. Adding an unrelated large project cannot arbitrarily change top results for an exact scoped query. The production fusion order is defined once in plan 05 §11.3 — RRF over channels within each shard, then a calibrated cross-shard merge with exact-match tiers first — and plan 05 owns the fixed-layout determinism plus repartition-drift property tests (05 §17); this plan contributes session fixtures and ablation baselines. + +### 5.4 Temporal resolution and ranking + +Hard eligibility precedes ranking: + +1. authorization/privacy and sanitized-output eligibility; +2. immutable resolved project/repository/worktree/ref set; +3. temporal cutoff and retention horizon; +4. provider/origin/kind/grain requirements; +5. required evidence relation (`produced`, `observed`, `proposed`, `copied`, and so on). + +Then compute explained features: + +- exact phrase/identifier and fielded lexical score; +- semantic/fuzzy/entity match; +- assertion validity at cutoff; +- supersession/current-state relation; +- authority/evidence/directness; +- query-to-project/ref/worktree/snapshot relevance; +- Turn/session/thread/agent proximity; +- source-versus-summary and summary freshness; +- copy/query/tool/protocol/inventory noise; +- diversity/novel evidence contribution; +- bounded recency appropriate to the chosen intent; +- confidence, contradiction, and coverage risk. + +Rank explanations name feature contributions and hard exclusions. They never expose secret text, model hidden reasoning, or an unverifiable “AI relevance” number. + +### 5.5 Diversity and representative policy + +After exact-hit preservation: + +- one logical cluster cannot fill the page through copied occurrences; +- cap per session/thread/agent/project/provider only when the selected intent benefits, and disclose every cap; +- preserve distinct correction-chain nodes for `Evolution` mode; +- preserve both sides of unresolved conflicts; +- prefer source messages over summaries for exact literals; +- prefer Turns over isolated messages when adjacent tool/code evidence is necessary; +- allow explicit `Forensic` mode to disable representative hiding. + +### 5.6 Task, ticket, initiative, dependency, and work-claim context + +Task/ticket context packets use the same temporal retrieval engine and the canonical graph from [`24-canonical-task-plan-graph-and-multi-agent-executor.md`](24-canonical-task-plan-graph-and-multi-agent-executor.md). They are not a global-board text dump and do not invent a second task-specific search path. + +There is no `TaskContextSelectorV1`, task query struct, or task-local scope/temporal/page/sort vocabulary. The plan 09 task-context use case accepts canonical `WorkItemVersionRefV1`, `DependencyVersionRefV1`, and `WorkClaimRefV1` values owned by plan 01 and used by plan 24, plus canonical `InitiativeId`, `ThreadId`, and `TurnId` values where needed, and losslessly lowers them into one `TraceQueryV1`: plan 16 produces `scope`, plan 01's `temporal` and `time` fields carry temporal semantics, and plan 05's registered task/relation attributes carry the canonical references. Saved task views persist that one canonical AST and its registry digest, never an application-only selector. Unknown or version-mismatched refs fail validation before candidate generation; they are not weakened to bare text filters. + +The context packet contains only evidence relevant through an explained typed relation: + +- current task/ticket statement and the supersession lineage of earlier statements; +- initiative membership and dependency edges valid at the cutoff; +- current/expired/conflicting work claims and agent owners; +- directly linked thread/Turn/session/workflow evidence; +- produced/observed Git/code/PR/check artifacts with relation class; +- blockers, decisions, outcomes, and handoffs backed by anchors; +- sibling-task summaries only when they share an initiative dependency, explicit handoff, overlapping work claim, affected artifact, or requested scope. + +An unrelated global board row, similarly worded ticket, stale sibling plan, or other project initiative is a hard negative. Project/repository/worktree/ref scope and task/claim/dependency filters apply before ranking. A claimed task defaults to its own current context; broader initiative/global context is opt-in and visibly separated. If two agents claim overlapping artifacts, coordination evidence can surface compactly, but unrelated sibling work cannot consume the task context budget. + +Current mode returns the active task decision/claim and links superseded task instructions. As-of (`AsOf`) mode reconstructs what the task packet contained at the cutoff without later status, dependency, branch, or sibling-summary leakage. Evaluation must include Rspack/Rsbuild/React Router initiatives whose tasks cross repository boundaries, same-title tickets in unrelated projects, stale board decisions, overlapping agents, and sibling summaries that are relevant by vocabulary but unrelated by typed dependency/scope. + +## 6. LCM summary DAG and context assembly redesign + +### 6.1 One raw source, one derived hierarchy + +LCM is a projection/use case over canonical activity, not a second message store/search product. A summary node records: + +```rust +pub enum SourceRangeRef { + OccurrenceRange { + thread_id: ThreadId, + source_instance_id: SourceInstanceId, + start: SourceOrder, + end_exclusive: SourceOrder, + source_watermark: VectorWatermark, + }, + SummaryNode { + node_id: SummaryNodeId, + node_digest: ManifestDigest, + }, + WholeThreadUnverified { + thread_id: ThreadId, + observed_watermark: VectorWatermark, + }, +} + +pub struct SummaryNodeV2 { + pub node_id: SummaryNodeId, + pub thread_id: ThreadId, + pub source_ranges: NonEmpty, + pub source_watermark: VectorWatermark, + pub temporal_horizon: TimeInterval, + pub created_at: UtcMicros, + pub summarizer: SummarizerDescriptor, + pub prompt_version: PromptVersion, + pub sanitization_receipt_id: SanitizationReceiptId, + pub content_ref: PayloadRef, + pub claim_refs: Vec, + pub lossiness: SummaryLossiness, + pub status: SummaryStatus, +} +``` + +- DAG sources are exact raw ranges or prior summary nodes; cycles and missing source coverage fail validation. +- `SummaryStatus` includes `imported_unverified` for §12.1 V1 imports whose source coverage cannot be proven: such a node carries a single whole-thread `SourceRangeRef` marked unverified, is stale for current mode by default, may navigate/expand, and never satisfies a source-coverage proof; DAG validation accepts missing provable coverage only in this status. +- New raw/correction evidence after the node horizon does not mutate the node. It marks the node stale for current mode and creates a successor summary if policy allows. +- Deleted/redacted/locked sources update eligibility and coverage; a non-content tombstone remains. +- Summary embeddings/indexes use the same privacy domain and versioned horizon. +- Summary text can retrieve sources but cannot independently prove a claim. + +### 6.2 Context assembly profile + +`ContextAssemblyRequestV1` starts from a `TraceQueryV1`, stable anchor, current Turn, or explicit result set and declares: + +- temporal answer mode/cutoff; +- requested grain and purpose (`resume`, `answer`, `hint`, `debug`, `compare`, `forensic`); +- project/provider/thread/agent scope; +- token, byte, result, latency, model, and graph budgets; +- source-versus-summary preference; +- required adjacent evidence kinds; +- diversity/copy policy; +- privacy/output capability; +- deterministic, recorded-result, or current-best-effort replay mode. + +The assembler executes in plan 05's `context/assembler.rs` (05 §5); plan 09 composes and authorizes the assembly use case and owns packet publication, and plan 24 supplies task-graph selectors only. The assembler selects, in order: + +1. decisive source anchor(s) and current/conflict lineage; +2. containing Turn and minimal adjacent messages; +3. necessary tool/edit/code/Git/PR/agent relations; +4. fresh summary coverage for omitted ranges; +5. bounded head/tail only when conversation framing requires it; +6. explicit omission/partial/locked/truncated ledger. + +Token accounting uses one tokenizer descriptor and reports estimated/actual tokens separately from characters and bytes. `context_max_tokens` can never secretly mean characters. + +### 6.3 Answer and synthesis contract + +Retrieval and context assembly always return the same typed evidence envelope. Optional synthesis is a separate policy-selected stage: + +- `evidence_only`: host receives context and synthesizes; +- `local_synthesis`: configured same-privacy-domain model returns a cited answer; +- `recorded_synthesis`: replay the historical answer/model result; +- `no_synthesis`: return result/context view only. + +A synthesis failure never discards retrieved evidence. `NoAnswerReason` is a closed, versioned enum carried in the §7.2 page envelope's `no_answer_reason` field with exactly these variants: + +- `no_relevant_evidence`; +- `scope_resolved_empty`; +- `shard_unavailable_or_conflicted`; +- `not_ingested_or_index_stale`; +- `retained_redacted_or_locked`; +- `historical_cutoff_excludes_evidence`; +- `all_candidates_below_threshold`; +- `budget_exhausted`; +- `synthesis_unavailable`. + +## 7.

No result row, deep link, or export embeds the anchor record. + +The referenced view types are concrete: + +```rust +pub enum RetrievalGrain { Message, Turn, Session, Thread, AgentSlice, WorkflowSlice, EvidenceBundle } + +pub struct SafeResultSummary { + pub title: SafeLabel, + pub snippet: Option, + pub matched_fields: Vec, + pub provider: ProviderId, + pub origin: MessageOrigin, +} + +pub struct OccurrenceCounts { + pub total_hidden: u32, + pub by_provider: BTreeMap, + pub by_session: u32, + pub by_project: BTreeMap, +} + +pub enum TemporalResultState { Current, HistoricalValid, Superseded, Revoked, Conflicted, Unknown } + +pub struct EvidenceRelation { + pub kind: EvidenceRelationKind, // produced | observed | proposed | copied | ... + pub evidence: Vec, + pub confidence: Confidence, +} + +pub struct HydrationCapability { + pub metadata_batch_get: bool, + pub authorized_resolution: bool, + pub cluster_expansion: bool, + pub replay: bool, + pub denied_reason: Option, +} + +pub struct RankExplanationViewV1 { + pub profile: RankingProfileRef, + pub final_score: FiniteF64, + pub components: Vec, // id, version, normalized, weight, contribution, state + pub hard_exclusions: Vec, + pub temporal_features: TemporalFeatureSummary, +} +``` + +`RankExplanationViewV1` is the plan 09/21-rendered safe view of plan 05's `RankExplanation`/`ComponentScore` (05 §11.3); it adds no scores of its own and exposes no secret text, hidden reasoning, or raw hashes. + +Every result can be hydrated, expanded to cluster members, opened in the Turn/session/thread/timeline, and used as a new query/context anchor without project/CWD switching. + +### 7.2 Page envelope + +Human-facing Markdown is the default. JSON/NDJSON is explicit. Plan 09 owns the one semantic typed view model; plan 21 owns its presentation/rendering and transport parity. + +Stable fields include: + +- `status`, `query`, `intent`, `temporal_mode`, `as_of`; +- `resolved_scope`, `profile`, `index_versions`, `watermark`; +- `results`, `summary`, `limit`, `returned`, `truncated`, `next_cursor`; +- `coverage`, `partial_shards`, `skipped_shards`, `unavailable_shards`; +- `caps`, `deduplicated_occurrences`, `warnings`, `no_answer_reason`; +- `latency`, `token_estimate`, and optional evaluation/profile identifiers. + +No compact default includes raw metadata blobs, transcript paths, full message bodies, summary sources, embeddings, or every cluster member. Safe metadata uses canonical batch-get; content/record loading uses separately authorized canonical resolution by stable anchor. + +### 7.3 Cursor binding + +The signed cursor is plan 05 §9's encoding of the extended domain `CursorClaimsV1` (plan 01) — this plan defines no parallel cursor type. For session-temporal queries those claims bind: + +- canonical query digest and intent/profile version; +- temporal mode/cutoff; +- immutable resolved scope-set ID/digest; +- authorization/privacy capability digest; +- catalog and owner-shard generations; +- index/model/ranker/cluster/summary versions; +- frozen vector watermark; +- last deterministic rank tuple; +- partial/unavailable shard dispositions. + +A changed scope, authorization, index generation, or profile returns a typed stale-cursor problem. It never resumes against a subtly different corpus. + +## 8. Real replay and evaluation program + +### 8.1 Corpus families + +Build a private, sanitized, versioned corpus from authorized local history: + +1. explicit user recall requests and corrections; +2. later prompts whose answer depends on an earlier Turn/session; +3. reformulated/abandoned `message_search` and LCM queries; +4. searches followed by anchor load/use versus ignored/fallback behavior; +5. old/new decisions, facts, plans, branches, PRs, checks, and corrections; +6. direct user prompt versus copied subagent/delegation/tool/schema rows; +7. parent/child/workflow duplication and agent-overlap coordination; +8. raw versus summary-DAG versus compaction replay; +9. cross-project Rspack/Rsbuild/React Router and sibling-plugin investigations; +10. exact error/path/API/config/tool/session/commit/PR identifiers; +11. conceptual paraphrases, misspellings, aliases, and renamed projects; +12. expected no-answer, wrong-scope, partial-shard, locked/redacted, and stale-index cases; +13. provider conformance across Codex, Claude, Cursor, Hermes, and every supported provider with sufficient data; +14. hint-engine retrieval envelopes and background-intelligence proposals from Plan 22; +15. task/ticket context packets, initiatives, dependencies, work claims, and relevant-versus-irrelevant sibling summaries, including cross-repository Rspack/Rsbuild/React Router work. + +Queries are frozen at an `available_at` cutoff. Candidates, summaries, branches, facts, corrections, and labels created later cannot enter a historical replay. Replay also rebuilds index statistics (for example BM25 document frequencies) from the frozen `available_at < t` corpus, so ranking features cannot leak future corpus statistics. + +The frozen research corpus this program draws on is pinned by its owner, plan [`13-research-provenance-and-context-anchors.md`](13-research-provenance-and-context-anchors.md): path set `/fast/tracedecay-redesign-research/*`, file mode `0600`, final user-message cutoff `2026-07-10T02:21:15.411Z`, integrity verified against plan 13's manifest hashes. The manifest distinguishes the broad supported-surface capture from the 28-record active-session raw-rollout fallback. Session-temporal evaluation inputs derived from it cite that manifest, and no private content from it enters the repository. + +### 8.2 Minimum evidence gates + +Before any V2 default ranking claim: + +- at least 500 real query episodes; +- at least 12 registered projects, including TraceDecay, Rspack, Rsbuild, React Router, and `rsbuild-plugin-react-router` when stores are available; +- at least 4 provider families and an explicit coverage report for every supported provider; +- at least 100 current-versus-historical/supersession cases; +- at least 100 cross-project/worktree/ref cases; +- at least 75 copied-message/subagent/workflow duplication cases; +- at least 75 raw-versus-summary/compaction/LCM assembly cases; +- at least 100 exact technical identifier/error cases; +- at least 100 no-answer/partial/locked/stale-index cases; +- at least 75 task/ticket/initiative/work-claim cases, including current-versus-superseded decisions and sibling/global-board pollution hard negatives; +- candidate pools and manual labels sufficient for at least 5,000 query-result judgments; +- independent double labels on at least 20% of judgments and every high-severity stale/current or privacy case. + +Cases can overlap strata.

Search Quality Lab: session-temporal workspaces + +This plan's replay/lineage/copy/summary/evaluation surfaces are workspaces inside the one Search Quality Lab (plan 15 §8) — not a separate Search Lab and not separate message, LCM, memory, and hint debug pages. + +### 9.1 Query workspace + +- query editor with exact protected literals; +- intent, temporal mode, `as_of`, grain, scope, provider/origin/kind, and evidence-relation controls; +- frozen corpus/watermark/profile/config/model selectors; +- current engine, historical engine, recorded result, and compare profiles; +- equivalent generated CLI/MCP/API/SDK request. + +### 9.2 Candidate waterfall + +- one column/lane per lexical/fuzzy/entity/graph/summary/semantic/time channel; +- native and normalized score, match fields, shard, rank, latency, cap, and exclusion; +- fusion and representative selection transitions; +- raw shard score calibration/RRF explanation; +- query/tool/schema/inventory penalties and diversity decisions; +- click any row to open the stable anchor and authorized source. + +### 9.3 Temporal lineage explorer + +- assertion current/valid/conflicted state; +- correction/supersession/contradiction graph; +- valid-time and transaction-time lanes; +- “what the engine knew then” versus “what it knows now” split view; +- branch/worktree/commit/PR state overlays; +- authority/evidence/confidence inspector; +- stale-result warning and winning/current rationale. + +### 9.4 Logical-copy and summary-DAG inspectors + +- representative plus hidden occurrence tree by provider/session/project/store; +- provider-native/linkage/copy evidence and uncertainty; +- summary DAG source ranges, horizon, coverage, model/prompt version, lossiness, stale state; +- raw-source expansion with exact omissions/truncation; +- context-assembly token/byte budget and selected/omitted blocks. + +### 9.5 Evaluation workspace + +- corpus/query/qrel/profile/config version browser; +- candidate-pool judgments, hard negatives, double-label disagreement, and adjudication; +- per-query and aggregate nDCG/MRR/Recall/precision/temporal/duplicate/calibration charts; +- project/provider/intent/time/scope/privacy strata heatmaps; +- regression list sorted by severity and largest rank/temporal change; +- then-versus-now replay with recorded source watermark and engine/config digests; +- redacted aggregate report and synthetic-fixture promotion. + +Lab replay is read-only against frozen inputs.

Product surfaces and controls + +Exact transport names derive from Plan 08/21's catalog.

Privacy, retention, and security + +- Only Plan 18 `Sanitized`/eligible content reaches lexical, summary, entity, vector, qrel, report, or model paths. +- Raw query literals can contain secrets. Treat query history as sensitive content; store protected refs or safe keyed features, never analytics plaintext by default. +- Logical-copy fingerprints are keyed inside one privacy domain. No global unkeyed content hash or cross-domain embedding similarity joins private messages. +- Dense/learned-sparse/rerank/synthesis models and indexes are local to the authorized privacy domain unless an explicit policy/config permits a remote processor and the content class is eligible. +- Catalog/federation metadata contains opaque locators, capability, counts, watermarks, and safe labels—not message/query/summary text. +- Qrels and rationales live in the activity shard's protected profile-evaluation family; this is not a separate physical shard. Committed fixtures are synthetic or minimally redacted and secret-scanned. +- Hydration rechecks current authorization, retention, redaction, and deletion. A stale cached result cannot reopen revoked content. +- Deletion/redaction propagates to lexical indexes, vectors, summaries, clusters, caches, context bundles, qrels, and reports; non-content provenance/tombstone remains where policy requires. +- Prompt injection in historical messages is content evidence, never active instruction. Context envelopes label source/origin and quote/sandbox retrieved material. +- Rank explanations reveal safe feature categories and matched safe fields, not hidden content, protected model prompts, raw hashes, or secrets. + +## 12. Migration and cutover + +### 12.1 Inventory/import + +Import read-only, idempotently: + +- V1 `sessions`, `session_messages`, FTS rows, provider metadata, parent/subagent/workflow links, Git spans, goals, tool events, and source offsets; +- LCM raw messages, external payload refs, summary nodes/sources, lifecycle/frontier/debt state, and redaction/lossiness markers; +- response-handle metadata as expiring operational evidence, never durable anchors; +- current eval fixture and live probe recipes; +- duplicate/identity-conflict stores as separate observed sources until explicit consolidation. + +Each imported row gets source/store identity, sanitization status, occurrence ID, owner route, temporal fields, and parity receipt. Missing provenance becomes `unknown`, not guessed. Two explicit escape hatches keep the import honest: + +- V1 summary nodes whose source ranges cannot be proven import as `SummaryStatus::imported_unverified` (§6.1) rather than failing DAG validation or fabricating coverage; they stay stale for current mode until re-summarization over verified sources. +- Mandatory `sanitization_receipt_id`s for the ~388k imported raw rows (master-plan scale envelope) are minted by capture's bulk sanitizer path (plan [`03-capture-crate.md`](03-capture-crate.md)) as a costed, restartable backfill stage with its own throughput budget and progress watermark — never per interactive read. + +### 12.2 Backfill + +Rebuild in bounded phases: + +1. occurrence/native identity and source coverage; +2. Turn/thread/agent/workflow/location relations; +3. logical copy clusters with evidence/confidence; +4. summary DAG source/horizon validation; +5. typed lexical/entity/time documents; +6. temporal assertion candidates and explicit relation imports; +7. optional semantic representations per privacy domain; +8. frozen replay corpus and V1/V2 shadow results. + +All stages are restartable, versioned, and watermarked. Re-clustering or re-summarization publishes a new projection generation; it does not rewrite prior receipts. + +### 12.3 Shadow and cutover + +- V1 remains authoritative while V2 executes read-only shadow queries at the same frozen eligible cutoff. +- Compare candidate/result anchors, current-state resolution, no-answer reason, coverage, output size, latency, and resource cost. +- Manually inspect every high-severity temporal/privacy/exact-ID regression. +- Cut over session/LCM reads only after PR 35I gates pass across CLI/MCP/API/dashboard/hooks and every supported provider host. +- There is no per-query fallback that silently changes semantics. During the bounded migration window, route generation selects one owner for a context and exposes the other as comparison evidence. +- After V2 default, archive V1 read-only for the plan-12 window; then PR 37I deletes live V1 message/LCM/search/ranking/render paths after restore/replay proof. + +## 13.

Kanban boards, plan outlines, DAGs, timelines, workload maps, executor views, repository views, and All are authorized projections over that graph, never independent databases or ambient routing state. + +**Goal:** Turn TraceDecay's captured Threads, Sessions, Turns, Agents, Goals, tools, code, Git, delivery, knowledge, skills, hints, and automation evidence into a durable coordination system that can decompose and execute cross-repository initiatives safely across Codex, Claude, Cursor, Hermes, and custom executors without duplicating work, losing provenance, leaking private context, or forcing every agent to observe a global board. + +**Architecture:** The profile activity shard owns an immutable task/plan event stream and current projections. `tracedecay-domain` defines the graph and lifecycle; `tracedecay-store` persists one owner-shard ledger; projectors attach task work to every other graph; query evaluates registered task values through the sole `TraceQueryV1` algebra; pure policy proposes decomposition, routing, readiness, fairness, retries, and sibling-materiality decisions; application authorizes and atomically applies effects; executor adapters run attempts through fenced leases and narrow capability grants; generated API/CLI/MCP/SDK/dashboard bindings expose the same use cases and typed views. + +**Decision:** A task is not a card row, an assignee string, a provider prompt, an automation run, a Git branch, or a work-claim heartbeat. Those are related entities with distinct identity and authority. `WorkItemId` is the canonical schedulable identity; `ExecutionAttemptId` is one try; `TaskLeaseId + fence_epoch` is execution authority; `WorkClaimV1` remains advisory coordination evidence; `ContextPacketManifestId` pins exactly what an executor was allowed to know. + +--- + +## 0. Contract lock + +This is the plan for a **native TraceDecay port-and-redesign of Hermes Kanban**, not a Hermes adapter. TraceDecay owns and ships the canonical task/plan graph, scheduler, attempts, leases, worker protocol, CLI/MCP/API/SDK surfaces, and Brain/Work UI. For each Hermes component, implementation must choose and document one of three paths: port the proven behavior or code under its MIT provenance, rebuild it against V2 contracts while preserving its regression corpus, or replace it with a demonstrably better TraceDecay design. A separately configured Hermes agent may still be an execution host or capture source, exactly as Codex or Claude may be, but the TraceDecay Kanban/task product never delegates to or depends on a Hermes runtime, board database, plugin, or scheduler. + +1. There is one canonical profile-owned initiative/plan/work-item graph. No repository, project, board, worktree, provider, plugin, dashboard, or executor creates a second source of task truth. +2. An initiative may span zero, one, or many projects, repositories, checkouts, worktrees, refs, and providers. Ownership remains the profile activity shard; scope is explicit relation evidence, not database placement. +3. `Initiative`, `Plan`, immutable `PlanVersion`, canonical `WorkItem`, dependency/gate, assignment, execution attempt, task lease, handoff, artifact, outcome, and cost are different typed entities. +4. “Task” and “ticket” are product vocabulary for a `WorkItem`. They never mint competing IDs or persistence tables. +5. A plan is a versioned graph. Editing it creates a new `PlanVersion`; in-flight attempts remain pinned to the versions they started with until an explicit revalidation decision cancels, supersedes, or permits them to continue. +6. Gating dependency edges form a DAG. Informational, evidence, similarity, and causal-candidate relations may contain cycles but never participate in readiness or critical-path computation. +7. Dependency readiness is derived from immutable events, typed gate expressions, schedules, budgets, policy, and active leases. It is not a mutable board-column string. +8. Decomposition policy is pure: it returns a typed proposed plan revision and explanation. Application revalidates scope, authorization, privacy, versions, cycles, budgets, and executor capabilities, then commits eligible effects atomically in the activity owner shard. +9. Autonomous decomposition within an enabled authority envelope does not create a preview/apply inbox. Human-authored plan changes are direct versioned commands with receipts. Human review gates may govern deliverables; they are not curation approval queues. +10. TraceDecay curation remains fully autonomous under plans 09 and 20. A curation run may be related to a work item or outcome, but there are no task-shaped Approve/Reject/Apply/Rollback controls for individual memories, facts, or managed-skill proposals. +11. Assignment expresses desired ownership/routing. Advisory `WorkClaimV1` expresses nearby-agent intent. Only a current fenced `TaskLeaseV1` grants execution authority. +12. Every active attempt owns one lease epoch. Completion, blocking, artifact publication, handoff, or side-effect receipt from a stale epoch is rejected, even if the stale worker still has a process or network connection. +13. Many hosts may schedule and execute concurrently. Atomic owner-shard compare-and-swap plus monotonically increasing fence epochs prevents double execution; PID liveness is optional local evidence, never distributed truth. +14. Every executor is registered through a versioned adapter/capability manifest. An assignee label never doubles as an executable name, profile path, provider, model, host, or authorization decision. +15. Requested and actual executor adapter, provider, model, model revision, reasoning effort, tool catalog generation, skills, capability grants, host, workspace binding, token/cost budget, and deadlines are pinned per attempt and recorded in receipts. +16. Allow/deny decisions are explicit by declared scope. Deny wins. A global wildcard does not silently grant mutation tools, MCP servers, remote egress, credentials, repository writes, Git writes, PR operations, or cross-project reads. +17. Agents receive a compact, versioned, sanitized context packet, not a path to the task database or a dump of the global board. Packet entries cite durable retrieval anchors and exact scopes. +18. Context packets include only relevant parents, sibling summaries/decisions, dependencies, acceptance criteria, worktree/branch bindings, constraints, handoffs, and retrieval anchors. Omitted or unavailable evidence is explicit. +19. Material sibling changes create new packet evidence. Plan 22 decides whether one exact Thread/Turn/Agent should receive a compact advisory at a safe host boundary; task events never broadcast directly into every prompt. +20. Tool output, API output, CLI output, MCP output, SDK models, and dashboard state are generated from the same application view models. No transport reimplements readiness, permissions, retry semantics, truncation, or task rendering. +21. Kanban, DAG, plan, timeline, causal, critical-path, workload, executor, repository, initiative, and All are saved authorized projections. “Current board” may be ephemeral UI state only and never supplies ownership, dispatch scope, or mutation scope. +22. Workspace paths are locators, not identity. Repository, project, checkout, worktree, ref, commit, and `CodeSnapshotId` remain distinct. A writable attempt binds exact versions before any edit. +23. TraceDecay never auto-stashes, resets, cleans, rebases, merges, force-pushes, deletes, or adopts a user-owned dirty worktree. Such conditions become typed blocks or separately authorized delivery workflows. +24. A terminal task result requires acceptance evidence or an explicit authorized exception receipt. Plain-text worker exit, process disappearance, or provider “success” is not proof of completion. +25. Retries reuse stable idempotency keys for already-authorized effects, create a new `ExecutionAttemptId` and lease epoch, consume a declared budget, and consult task/executor/provider circuit breakers. +26. Cancellation is first class: requested, acknowledged, effect-stopped, reconciled, and terminal dispositions are distinguishable. An unknown remote cancellation never permits immediate unsafe reuse of the old lease or provider thread. +27. Artifacts, logs, comments, prompts, summaries, metadata, model output, and errors enter as `Unclassified` and pass plan 18's sanitizer before any ordinary store, index, event, packet, output, export, or model sink. +28. Hidden chain-of-thought is never requested or inferred. Only provider-exposed reasoning artifacts, messages, summaries, decisions, tool events, and evidence are linkable. +29. Every query/result states scope resolution, graph/plan versions, watermarks, authorization coverage, partial/unavailable components, and anchorability. Empty never means “no work exists” when coverage is incomplete. +30. Migration ends with one scheduler, one lease authority, one context-packet assembler, one task query engine, one public capability catalog, and one dashboard state model. Compatibility adapters are bounded and deleted after receipts prove cutover. +31. Task reads use registered `EntityKind`, attribute, traversal, facet, aggregate, projection, and sort values inside the one domain `TraceQueryV1`; `TaskQueryV1`, `TaskContextSelectorV1`, board filter DSLs, and transport-specific task query bodies are forbidden. Convenience selectors compile losslessly to `TraceQueryV1` and expose the canonical digest. +32. Every accepted task command appends one canonical `task_graph_events` record and its projection/external-effect outbox entries in the same owner-shard transaction. Projectors, scheduler checkpoints, subscriptions, audit views, and replay consume that committed journal; notifier/SSE/outbox delivery is never a second event truth. +33. `RedundancyMode::SharedExecution` is coordination intent, not permission for two authoritative executors on one work item. Concurrent collaborators are explicit child work items under an aggregate parent; provider-internal subagents remain attached to the one primary attempt and use only its brokered grants. + +## 1. Product objective and non-goals + +### 1.1 Product objective + +TraceDecay should expose work as part of the same “brain” as conversations, agents, code, Git, delivery, knowledge, and time: + +- a user creates or discovers one initiative, such as a coordinated Rspack/Rsbuild/React Router change; +- TraceDecay resolves the exact authorized repository/project/worktree set and current evidence; +- deterministic or model-assisted decomposition proposes a versioned task subgraph; +- the application validates and records independently leasable work with typed dependencies and acceptance criteria; +- routing policy selects eligible Codex, Claude, Cursor, Hermes, or custom executor classes without overloading an assignee string; +- workers receive narrow context packets and capability grants, execute in isolated exact workspaces, and publish structured handoffs/artifacts/outcomes; +- verifier and synthesizer work items join parallel research before implementation tasks unlock; +- the dashboard can pivot the same selection between plan, board, DAG, timeline, causal, repository, workload, executor, and critical-path views; +- agents see only their relevant slice, while authorized humans can query All without copying tasks into global boards; +- every decision is replayable from versions, evidence, anchors, policy/config/catalog manifests, and receipts. + +### 1.2 Non-goals + +- No generic project-management suite, arbitrary spreadsheet, issue-tracker clone, or untyped workflow DSL. +- No replacement for GitHub issues/PRs, provider-native goals, Claude workflows, Codex plans, or external schedulers.

Lease, attempt, start manifest, physical `task_leases`/`execution_attempts` rows, broker calls, events, and receipts carry both values and must agree. The set pins its ordered grant IDs, attempt, lease/epoch, policy manifest, effective configuration snapshot/digest, and catalog snapshot. Revocation appends a fenced revocation event/epoch without changing the set; any different grant contents require a new set on a new attempt/lease. Mutating a set behind a stable ID is forbidden. + +`WorkClaimV1` from Plan 01 remains an advisory statement that an agent intends or appears to work on a scope. It drives nearby-agent/duplicate-work evidence and may suggest an assignment, but it cannot authorize tools, reserve budget, block scheduling, or complete a work item. `TaskLeaseV1` is application-issued execution authority and always points to one attempt. `TaskLeaseProofV1` is a short-lived unforgeable proof bound to lease/attempt/executor/epoch; its signature/nonce is protected control-plane material and never appears in ordinary stores, logs, prompts, UI, CLI, MCP, exports, or research anchors. Proof signatures use a profile-local HMAC signing key under the plan 18 key lifecycle (key ID plus rotation recorded in the profile catalog, matching the plan 12/19 receipt mechanism; no asymmetric PKI); only the application service verifies proofs, and key rotation invalidates outstanding proofs at the next issuance or heartbeat boundary. + +```rust +pub struct ExecutionAttemptV1 { + pub id: ExecutionAttemptId, + pub work_item: WorkItemVersionRefV1, + pub plan_version: PlanVersionId, + pub ordinal: u32, + pub assignment: AssignmentId, + pub executor: ExecutorRegistrationId, + pub executor_instance: ExecutorInstanceId, + pub fence_epoch: u64, + pub requested_route: ExecutorRouteV1, + pub actual_route: Option, + pub workspace: WorkspaceBindingId, + pub context_packet: ContextPacketManifestRefV1, // immutable start packet + pub accepted_context_packet: ContextPacketManifestRefV1, // monotonic accepted ordinal; initially equals start packet + pub capability_grant_set_id: CapabilityGrantSetId, + pub capability_grant_set_digest: ManifestDigest, + pub budget: AttemptBudgetV1, + pub state: AttemptStateV1, + pub started_at: Option, + pub ended_at: Option, + pub outcome: Option, +} +``` + +Attempt rows are immutable except for monotonic lifecycle fields applied by fenced commands; requested route, assignment, executor, workspace, start packet, grants, budget, ordinal, and fence epoch are fixed at creation. `accepted_context_packet` may advance only to a higher sealed ordinal through the fenced `context_packets.accept` command and never changes start authority. State history remains append-only in the canonical `task_graph_events` journal; the current attempt row carries only the latest state/version and terminal refs for efficient reads. The `work_items.current_attempt_id` pointer is denormalized and transactionally checked, never reconstructed by `MAX(started_at)`. + +Attempt states are closed and monotonic except explicit recovery transitions: `Prepared`, `Leased`, `Starting`, `Running`, `CancellationRequested`, `Stopping`, `Reconciling`, `Blocked`, `Succeeded`, `Failed`, `Cancelled`, `TimedOut`, `Lost`, `Superseded`, `Deferred`. `Deferred` is terminal for that attempt and pairs with outcome execution disposition `deferred`, product result `no-op`, and a registered terminal reason such as `RateLimited`; it does not increment task-quality/consecutive-failure counters. Terminal attempts never reopen; retry/requeue creates a new attempt. + +One work item has at most one active lease and one primary executor. When a user or decomposition policy requests `RedundancyMode::SharedExecution`, application atomically creates independently leasable child work items with explicit `ExpandsTo`/dependency/handoff relations and makes the parent an aggregate gate; it never issues participant leases against one work item. A provider may spawn internal subagents inside the primary attempt, but they are related Agent/Thread/Turn evidence, inherit only the primary attempt's brokered capabilities, and cannot obtain an independent lease, budget, writable reservation, or terminal authority. Sequential handoff between agents creates a new attempt/epoch unless it stays inside one adapter-owned attempt under the same primary authority. UI/API/SDK describe this as a shared-work group, not “multiple owners of one task.” + +### 4.7 Executor registration and route + +```rust +pub struct ExecutorClassId(pub EntityId); + +pub enum ReasoningEffortV1 { + Minimal, + Low, + Medium, + High, + Maximum, + ProviderSpecific(NativeKindCode), +} + +pub enum ExecutorAdapterKindV1 { Codex, Claude, Cursor, Hermes, Custom(NativeKindCode) } + +pub struct ExecutorRegistrationV1 { + pub id: ExecutorRegistrationId, + pub class: ExecutorClassId, + pub adapter: ExecutorAdapterKindV1, + pub adapter_version: ComponentVersion, + pub host: HostInstanceId, + pub profile: Option, + pub capabilities: ExecutorCapabilityManifestV1, + pub supported_providers: BTreeSet, + pub supported_models: BTreeSet, + pub supported_effort: BTreeSet, + pub workspace_modes: BTreeSet, + pub concurrency: ConcurrencyEnvelopeV1, + pub privacy_residency: ModelResidencyV1, + pub heartbeat_at: UtcMicros, + pub expires_at: UtcMicros, + pub state: ExecutorRegistrationStateV1, + pub manifest_digest: ManifestDigest, +} + +pub struct ExecutorRouteV1 { + pub adapter: ExecutorAdapterKindV1, + pub provider: ProviderId, + pub model: ModelCapabilityRefV1, + pub reasoning_effort: ReasoningEffortV1, + pub skills: Vec, + pub tool_catalog: CatalogSnapshotRefV1, + pub grant_template: CapabilityGrantTemplateId, + pub fallback_policy: ExecutorFallbackPolicyV1, +} +``` + +`ActualExecutorRouteV1` records what ran, including fallback reason, actual provider/model/revision/effort, host/runtime, tool schema digest, loaded skill versions, and the capability-grant-set ID/digest pair.

Work that must write several repositories decomposes into independently fenced child work items, one writable binding each, plus explicit dependency/integration gates. No capability grant widens a singular attempt into multi-write authority. Before start, application re-resolves identity and verifies base commit, worktree ownership, clean/dirty state, active agents/leases, branch collision, and code-index generation. Drift produces a rebind, block, or cancel decision; it never silently switches to the base checkout. + +Worktree lifecycle is an application workflow with `Requested → Reserved → Created/Adopted → Bound → InUse → Releasing → Preserved/Removed/Failed`. User-created or dirty worktrees default to `Preserved`. TraceDecay-created disposable worktrees may be removed only after no active lease/agent, artifact retention, Git safety checks, and a durable cleanup receipt. Branch/rebase/merge/PR/release effects remain separately cataloged delivery commands with their own grants and receipts. + +### 4.9 Versioned context packet + +```rust +pub struct ContextPacketManifestV1 { + pub id: ContextPacketManifestId, + pub ordinal: u64, + pub attempt: ExecutionAttemptId, + pub addressee: AgentAddressV1, + pub work_item: WorkItemVersionRefV1, + pub plan_version: PlanVersionId, + pub scope_resolution: ScopeResolutionId, + pub workspace: WorkspaceBindingId, + pub acceptance: Vec, + pub entries: Vec, + pub omissions: Vec, + pub source_watermarks: VectorWatermark, + pub canonical_query_digest: PrivacyDomainBoundLocatorDigest, + pub access_policy_digest: AccessPolicyDigest, + pub visibility_digest: AccessPolicyDigest, + pub sanitizer_floor: SanitizerFloorId, + pub policy_manifest: PolicyManifestRef, + pub effective_config_snapshot_id: EffectiveConfigSnapshotId, + pub effective_config_digest: EffectiveConfigDigest, + pub catalog_snapshot: CatalogSnapshotRefV1, + pub max_tokens: u32, + pub actual_tokens: u32, + pub tokenization_digest: ManifestDigest, + pub created_at: UtcMicros, + pub expires_at: UtcMicros, + pub manifest_digest: ManifestDigest, +} + +pub struct ContextPacketEntryV1 { + pub ordinal: u32, + pub kind: ContextPacketEntryKindV1, + pub subjects: BoundedVec, + pub anchors: BoundedVec, // validation requires 1..=16 + pub evidence_class: EvidenceClass, + pub valid_from: Option, + pub valid_to: Option, + pub observed_from: UtcMicros, + pub observed_to: Option, + pub access_policy_digest: AccessPolicyDigest, + pub sanitizer_receipt: SanitizationReceiptId, + pub token_cost: u32, + pub relevance_micros: i32, // registered fixed-point scale; no float serialization + pub inclusion_reason: ContextInclusionReasonV1, +} + +pub enum ContextPacketEntryKindV1 { + Objective, + ParentHandoff(HandoffId), + RelevantSiblingSummary { work_item: WorkItemId, handoff: Option, decision: Option }, + DependencyState(DependencyId), + Acceptance(AcceptanceCriterionId), + Decision(TaskDecisionId), + Constraint, + ScopeEntity(EntityRef), + WorkspaceBinding(WorkspaceBindingId), + CodeOrGitEvidence, + PriorAttempt(HandoffId), + MemoryOrSkill(EntityRef), + Contradiction, +} + +pub struct AgentAddressV1 { + pub attempt: ExecutionAttemptId, + pub executor: ExecutorRegistrationId, + pub provider: ProviderId, + pub agent_instance: Option, + pub session_id: Option, + pub thread_id: Option, +} +``` + +`AgentAddressV1` addresses the executor bound to one attempt; native session/thread identities attach once the host starts the worker and reports them. It is distinct from plan 22's `SuggestionAddressV1`, whose fields are all mandatory live Thread/Turn delivery coordinates: plan 22 derives its own addressee from attempt/packet evidence and never treats a packet address as delivery authority. + +Offer acceptance and packet/attempt creation form one atomic admission protocol, not a nullable cycle. The accept handler reads the exact immutable offer pins, completes any workspace preparation and packet assembly outside the task-graph writer transaction, preallocates `ExecutionAttemptId`, `ContextPacketManifestId`, `TaskLeaseId`, and `CapabilityGrantSetId`, and builds a `PreparedContextPacketV1` without persisting it. It then opens one owner-shard transaction that CAS-checks the offer revision plus every pinned input and atomically marks the offer accepted, activates its exact offered assignment, inserts the sealed packet manifest/entries, immutable attempt, lease, grant set, reservations, canonical events, adapter-start outbox row, and idempotency result. A validation/CAS failure persists none of them and leaves no partial start. Canonical packet rows therefore require non-null `attempt_id`; nullable legacy/import rows are nonauthoritative evidence and cannot be attached to a V2 lease. Recovery quarantines any pre-cutover orphan rather than guessing a link. + +The sealed physical lowering owned by plan 02/PR 6G must retain every manifest field above: addressee, plan/work-item versions, scope/workspace/acceptance refs, query/access/visibility/sanitizer/policy/config/catalog digests, source watermark, token budget/actual/tokenization digest, timestamps/expiry, ordinal, state, and manifest digest. Every entry row retains its typed kind payload, canonical subjects, at least one anchor, evidence class, valid/observed time, access/sanitizer refs, token cost, relevance, and inclusion reason; normalized child tables or protected typed blobs are allowed, but dropping a field is not. Domain↔store→projector→API round-trip fixtures compare the complete sealed manifest digest. + +Packet assembly is deterministic for a frozen input manifest: + +1. resolve exact task/plan/scope/workspace/access versions; +2. include objective, constraints, acceptance, and blocking dependency state; +3. include completed parent handoffs and decisions; +4. rank siblings only when dependency, shared symbol/file/test/goal/decision, or explicit plan relation proves materiality; +5. retrieve temporally correct supporting Turns/messages/summaries through Plan 23; +6. include prior attempts that prevent repeated failure; +7. apply privacy/egress/tool grants and sink firewalls; +8. allocate token budget by mandatory class, then evidence value and diversity; +9. record every omitted class/reason and coverage gap; +10. seal canonical query, config, catalog, policy, visibility/access, sanitizer, scope/workspace/snapshot, vector watermark, tokenization, entry, anchor, omission, and expiry digests before executor start. + +An updated packet never rewrites the packet an attempt started with. It creates a new ordinal bound to the same attempt, route, workspace, grants, access, and policy ceilings. The executor accepts it only through fenced `context_packets.accept { attempt, lease, fence_epoch, expected_accepted_packet, candidate_packet, effective_after_turn, idempotency_key }` at a declared safe Turn boundary. The command verifies a higher ordinal, current lease/attempt, digest/access compatibility, expiry, and no authority widening; it appends `ContextPacketAccepted`, updates only the monotonic `accepted_context_packet` projection, and returns the effective boundary. Plan 22 may deliver a small advisory pointing to the candidate when the exact current Turn is materially affected. Raw prompts, hidden reasoning, unrestricted sibling logs, credentials, and unrelated board text are ineligible. + +### 4.10 Canonical event vocabulary and invariants + +`task_graph_events` is the authoritative command-event journal for this bounded context. Every accepted mutation appends one or more sanitized versioned canonical events with correlation/causation, actor, owning profile shard, task/plan versions, policy/config/catalog digests, and audit ref in the same transaction as current rows, idempotency result, and outbox entries. `execution_attempt_events`, lease-event tables, and other specialized histories are typed index/detail lowerings of those event IDs, never independently authored lifecycle truth. Projectors, scheduler checkpoints, query/as-of replay, subscription read models, and audit consume the journal in sequence order; post-commit notifier, SSE, and external-effect outbox records carry journal ranges/refs and cannot invent or acknowledge canonical state. Event families include: + +- initiative created/updated/paused/resumed/retired; +- plan version created/activated/superseded/rejected-by-invariant; +- work item versioned/retired/replaced/reopened/transition-reversed/paused/cancel-requested/archived; +- dependency/gate added/removed/satisfied/invalidated; +- acceptance criterion added/evaluated/manually-attested/reviewed/satisfied/failed/excepted; +- decision recorded/superseded/invalidated; +- assignment proposed/accepted/replaced/expired; +- task offer issued/accepted/declined/expired/revoked; +- advisory work claim observed/heartbeat/completed/expired; +- executor registered/heartbeat/draining/expired/quarantined; +- lease issued/heartbeat/extended/revoked/expired/fenced; +- attempt prepared/started/progressed/blocking/cancelled/timed-out/lost/terminal; +- context packet built/accepted/superseded/expired; +- handoff/artifact/outcome/cost published/reconciled; +- workspace reserved/bound/drifted/conflicted/released; +- scheduler/policy decision and no-action reason; +- external effect requested/acknowledged/reconciled/compensated/unknown. + +Invariant checks run in domain validation and owner-shard transactions: + +- exactly one active lease per work item and one work item per lease; +- lease epoch strictly increases per work item; +- attempt terminal event and active-lease release are atomic; +- completion references the current attempt, lease epoch, work-item version, packet, and acceptance evaluation; +- active attempt route/grants/workspace/start packet are immutable; accepted packet may only advance through the fenced higher-ordinal acceptance event without widening authority; +- a plan activation cannot introduce gating cycles, missing work-item versions, unauthorized scope, or unresolved required validators; +- a task cannot be simultaneously terminal and actively leased; +- a cancelled/retired task cannot become ready without a versioned reopen command; +- artifact/handoff/outcome refs cannot cross privacy domains without an authorized sanitized representation; +- no event accepts arbitrary JSON extension fields outside a registered schema. +- every specialized task/lease/attempt history row and every outbox entry references an existing canonical journal event in the same commit; replaying the journal rebuilds all current/projection state without consuming SSE, notifier, or adapter delivery history as authority. + +### 4.11 Shared diagnostic and action envelope + +Plan 01 owns and defines these domain types; this plan imports them and owns only the cross-product diagnostic pattern adopted by plan 09 remediation findings, plan 06 policy/hint diagnostics, plan 22 suggestion actions, and task/executor diagnostics here: + +```rust +use tracedecay_domain::{DiagnosticActionV1, DiagnosticEnvelopeV1}; +``` + +Unknown action kinds remain visible as disabled informational rows with their code, evidence, and update requirement; renderers never drop them, guess a command, or execute free text. `legal_capabilities` and application authorization remain authoritative at invocation time, so an envelope is evidence plus a proposal—not authority, a lease, or an approval queue. Storage retains diagnostic envelopes through their subject/evidence horizon and indexes `(diagnostic_code, observed_at)`, `(subject, state)`, and `expires_at` in the subject's owning shard. + +## 5.

No SQL transaction remains open across network, process, filesystem, Git, or model calls. + +### 5.3 Fencing and concurrent writers + +`task_leases` stores `(work_item_id, attempt_id, executor_registration_id, fence_epoch, state, heartbeat_at, heartbeat_sequence, expires_at, expected_work_item_version, capability_grant_set_id, capability_grant_set_digest, start_packet_id, start_packet_ordinal, start_packet_manifest_digest)`. `execution_attempts` carries the same grant-set ID/digest pair. A digest-only grant pointer is forbidden, and both rows reference the same immutable grant-set entity. The last three lease fields are the exact immutable start `ContextPacketManifestRefV1`; a digest-only packet pointer is forbidden. `attempt_context_packet_acceptances(attempt_id, packet_id, packet_ordinal, packet_manifest_digest, prior_packet_id, prior_packet_ordinal, effective_after_turn_id NULL, accepted_event_id, accepted_at, PRIMARY KEY(attempt_id, packet_ordinal))` is append-only. Attempt creation inserts ordinal one with prior=start, null Turn boundary (effective before execution), and the `AttemptStarted` event; every later row requires a non-null safe Turn boundary and a strictly higher sealed ordinal. The current projection selects the highest row, and the attempt's `accepted_context_packet` must match it. Acceptance never mutates the lease/start packet. + +`work_items` stores the current row `(work_item_id PRIMARY KEY, current_version_id, current_plan_version_id, revision INTEGER NOT NULL, disposition, resolution, current_attempt_id NULL, active_lease_id NULL, next_fence_epoch INTEGER NOT NULL, readiness_digest BLOB NOT NULL, readiness_updated_event_id, updated_at)` — one row per work item in the activity owner shard, retained for the life of the work item, indexed on `(disposition)`, `(resolution)`, and `(current_attempt_id)`. Legal pointer states are explicit: **idle/never-started** has both pointers null; **active** has both non-null and naming the same nonterminal attempt/lease pair; **terminal-history** retains the terminal `current_attempt_id` and has null `active_lease_id` until a new attempt atomically replaces both. No other combination is legal. SQL null-shape CHECKs plus deferred foreign-key/transaction validators and property tests enforce the three-state union; terminal commit clears only the lease pointer. `readiness_digest` is a deterministic digest over the canonical gating inputs: current work-item version, disposition, gating dependency edge states, gate-expression results, schedule/`NotBefore` marks, and budget-exhaustion flags. It is recomputed inside the same owner-shard transaction as any mutation of those inputs (gating-edge add/remove/satisfy/invalidate, plan-version publish, disposition change, budget event) — canonical transactional state maintained at edge-mutation time, never projector output. The `EffectiveReadinessV1` projection may lag it freely without affecting claim safety. + +Offer acceptance/issuance uses one owner-shard writer transaction: + +1. authenticate the addressed executor and CAS-check `AcquireTaskLeaseCommandV1.expected_offer_revision` against the same `Open` offer whose immutable work-item, assignment, route, rationale, policy, config, catalog, readiness, and expiry pins were used for preparation; +2. verify current work-item/plan versions and CAS-check `expected_readiness_digest` against the stored `work_items.readiness_digest` in the same transaction (recomputing from canonical gating tables only to produce a typed mismatch diagnosis); +3. activate the offer's exact proposed assignment, or validate that it still names the unchanged accepted manual assignment; never synthesize or reroute an assignment during acceptance; +4. reject any unreconciled old lease/effect, then increment the work item's durable `next_fence_epoch`; +5. insert the preallocated sealed packet/entries, attempt, lease, and immutable capability grant set as one non-null referential set whose ID/digest pairs agree; +6. reserve executor/provider/project/initiative capacity, budget, and the exact writable resource; +7. CAS the offer to `Accepted`, append assignment/offer/attempt/lease/canonical journal events, specialized index rows, adapter-start outbox row, and idempotency result, then return the sealed start manifest. + +Every mutating attempt call includes lease ID, epoch, attempt ID, executor ID, idempotency key, and expected work-item version. A stale writer receives `task_lease_fenced` and a safe stop directive. Lease expiry marks authority unavailable; it does not prove external work stopped. Recovery enters `Reconciling`, queries the adapter when possible, and only then requeues or quarantines. Unknown external state blocks effects that are not safely idempotent. + +SQLite remains valid for a single activity-shard authority if all hosts reach the daemon/application service rather than opening the file. A future replicated store may implement the same repository/CAS contract; domain/application semantics do not depend on SQLite locks or host PIDs. + +### 5.4 Indexes, retention, and recovery + +Indexes cover initiative/plan/version, disposition/resolution/readiness, gating parents/children, assignment target, executor class/adapter/provider/model/effort, active lease expiry, attempt state/time/outcome, exact project/repository/worktree/ref/snapshot relation, actor/agent/session/Turn/goal, artifact/PR/check, schedule/deadline, priority, budget, and retrieval-anchor digest. + +Maintain incremental topological order and dependency counters per active plan projection. They are rebuildable from plan versions and events. Critical-path/workload summaries are projections with manifests, never mutable truth columns. + +Retention rules: + +- retain plan/task identity, versions, terminal outcomes, lease epochs, audit refs, and safe provenance for the policy floor; +- compact progress/heartbeat events into checkpointed summaries only after source horizons and replay tests; preserve terminal/cancellation/fencing transitions; +- logs and large artifacts use separate protected retention classes and holds; +- packet payload expiry may leave a manifest/tombstone with anchors, entry kinds, digests, omissions, and access disposition; +- executor heartbeats expire current visibility but retain registration history; +- saved view definitions remain encrypted and are reauthorized on every open; +- deletion follows plan 18 descendant invalidation and anchor tombstone rules. + +Startup recovery verifies schema/integrity, active lease/attempt bijection, monotonic epochs, dangling reservations, graph cycles, topological manifests, packet refs, outbox steps, and executor registrations.

Cross-repository edges require explicit plan scope, dependency, provider, code, Git, or session/workflow evidence. + +Task↔Thread/Session/Turn/Agent relations are explicitly many-to-many and bitemporal. One long thread may contribute to several tasks/branches/PRs; one task may span many agents and sessions. Relation versions carry observed/valid intervals, role (originated, instructed, executed, reviewed, mentioned, handed off), evidence, and packet/attempt provenance. Projectors never collapse this into `task.session_id` or infer ownership from the latest/current session. + +### 6.3 Material sibling changes + +The projector emits a bounded candidate only when a sibling/parent/child event can change the target agent's next action: + +- dependency satisfied, failed, cancelled, or invalidated; +- handoff or required artifact published; +- shared decision superseded; +- acceptance criterion changed or newly failed; +- shared file/symbol/test/worktree claim creates direct overlap; +- branch/base/PR/check state invalidates a packet assumption; +- relevant sibling produced a result that prevents duplicate research; +- verifier rejected evidence needed by implementation; +- budget/capability/scope change makes the current route invalid. + +Candidate includes exact target work item/attempt/Agent/Thread/Turn if known, event/version refs, safe summary eligibility, anchors, materiality features, and suppression hints. It does not contain rendered prompt text or delivery authority. + +## 7. Task query algebra and saved projections + +### 7.1 One typed algebra + +Use the exact plan-01 `TraceQueryV1`; do not introduce `TaskQuery`, `TaskSource`, `TaskOperator`, `TaskContextSelectorV1`, dashboard-only filters, or a pipeline DSL. Plan 01's existing fields carry the task contract: + +| `TraceQueryV1` field | Registered task use | +|---|---| +| `entity_kinds` | Initiative, Plan, PlanVersion, WorkItem, Dependency, Assignment, WorkClaim, TaskLease, ExecutionAttempt, Executor, ContextPacket, Handoff, Artifact, Outcome, CanonicalEvent. | +| `scope` / `temporal` / `time` | Exact `ScopeSelectorV2`; current, bitemporal as-of, evolution, or forensic task state. | +| `attributes` | IDs/aliases, lifecycle/readiness/reason, gates, acceptance, assignment/route/provider/model/effort, lease/attempt/outcome/retry, packet, budget/cost, and graph relation filters through registered attribute IDs. | +| `traversal` | Bounded parents/children/blockers/critical path/agent/Turn/evidence/Git/delivery traversal through registered predicates. | +| `facets` / `aggregates` / `projection` / `sort` | Registered task groupings, workload/accounting aggregates, sealed view projection, and stable ordering. | +| `page_size` / `snapshot` / `explain` / `budget` | Shared bounds, frozen/current semantics, explanations, and cost controls. | + +`work_items.query`, saved task views, SDK helpers, and UI builders accept or construct this same struct, canonicalize it through plan 05, and expose its canonical digest. A task facade may provide typed builder methods only; serialization and execution remain `TraceQueryV1`. + +Predicates cover IDs/aliases, initiative/plan/version, kind, lifecycle/readiness/reason, dependency/gate, acceptance, priority/schedule/deadline, assignment/executor/provider/model/effort, lease/attempt/outcome/retry, scope entity, actor/agent/session/Turn/goal, tool, file/symbol/diagnostic/test, Git/delivery entity, artifact/handoff, budget/cost, packet status, event/time/evidence, and text search under Plan 23 semantics. + +Traversal operators are typed and bounded: + +- parents, children, ancestors, descendants, blockers, unblockable, gates, replacements, subplans; +- verifier/synthesizer/reviewer/implementation neighbors; +- attempts/executors/agents/Turns/tools/artifacts/outcomes; +- repository/project/worktree/ref/commit/PR/check/release evidence; +- handoff path, critical path, causal-evidence path, shortest legal path; +- graph-of-graphs pivot by stable entity selection. + +### 7.2 Query correctness + +- resolve and authorize `ScopeSelectorV2` before shard planning; +- capture active plan/work-item/projection versions and vector watermarks once per page/frozen investigation; +- execute task lifecycle reads in the activity owner shard and join project evidence through content-free routes plus authorized hydration; +- never compare uncalibrated per-shard text scores as exact global order; +- cursor binds canonical query digest, scope resolution, versions, authorization digest, sort, and expiry; +- partial/unavailable project evidence does not hide owner-shard task truth; it marks joined fields/claims partial; +- `AsOf` reconstructs state from event/validity time and never reads current readiness into historical output; +- critical path reports unknown segments and methodology; +- every result exposes `RetrievalAnchorId`s or an anchor-creation workflow result, never only an expiring response handle. + +### 7.3 Required query examples + +Golden `TraceQueryV1` fixtures cover: + +- cross-repository initiative critical path: `entity_kinds=[WorkItem]`, exact project-set `scope`, registered initiative attribute, bounded dependency traversal, remaining-critical-path aggregate/projection, attempt/workspace/PR/check evidence joins, slack sort; +- compact exact agent slice: `entity_kinds=[WorkItem]`, registered relevant-agent/attempt attributes, bounded parent/material-sibling traversal, compact agent projection; +- executor fleet pressure: `entity_kinds=[ExecutionAttempt]`, registered starting/running/reconciling attributes, executor/provider/model/effort facets, count/runtime/cost/lease-expiry/retry aggregates; +- stale lease recovery: `entity_kinds=[TaskLease]`, expiry attribute, bounded attempt/executor/workspace/last-effect traversal, recovery projection. + +Fixtures serialize through generic query, task convenience endpoint, saved view, subscription, CLI JSON, MCP JSON, SDKs, and dashboard and must produce one canonical digest/result; no fixture is parsed from the prose above. + +### 7.4 Saved authorized projections + +`SavedTaskViewV1` stores an encrypted canonical `TraceQueryV1` with its mandatory explicit `query.scope`, canonical query/scope digests, projection/lens and grouping/sort specs, layout/presentation preferences, owner, sharing policy/grants, live-versus-frozen mode, frozen plan/entity/projection versions plus vector watermark when selected, config/catalog/schema versions, optimistic view version, timestamps, and revocation state. It stores no copied result set and no second scope selector. Opening it reauthorizes and replans against current or exactly pinned frozen versions; a missing retired frozen input is explicit unavailable coverage, never silent current fallback. + +Plan 02/PR 6G lowers those fields losslessly: `saved_task_views` retains protected query ref/digest, derived scope digest, lens/projection/group/sort/layout blobs, owner/sharing refs, snapshot mode and frozen manifest/watermark refs, config/catalog/schema generations, version, timestamps, and revocation; `task_view_shares` retains grant version, grantee, classification, expiry, and revocation event. The same sealed model powers reopen, simultaneous overlapping board instances, API/SDK/CLI/MCP reads, and migration fixtures. + +Built-in lenses: + +- `InitiativeOverview`; +- `PlanOutline`; +- `KanbanBoard`; +- `DependencyDag`; +- `CriticalPath`; +- `TaskTimeline`; +- `CausalEvidence`; +- `Workload`; +- `ExecutorFleet`; +- `RepositoryWork`; +- `AgentRelevantSlice`; +- `AllAuthorizedWork`. + +The lens changes presentation and default projection only. It never changes the selected canonical entity set or silently expands scope. An agent view defaults to `RelevantToAgent` and material neighbors; a human with an All grant may choose `AllAuthorizedWork`. Sharing follows Plan 11/18 protected-view preview, classification, expiry, and revocation rules. + +## 8. Pure policy design + +Add pure modules under `crates/tracedecay-policy/src/task_graph/` with explicit inputs, clocks, fixed-point scores, manifests, and explanations. + +### 8.1 Decomposition + +`DecompositionPolicyV1` accepts a frozen initiative/plan/work-item snapshot, exact scope resolution, available evidence/anchors, executor capability snapshot, budgets, configuration, and optional schema-valid model proposal. It returns `NoChange` or `PlanRevisionProposalV1` containing work-item versions, dependency/gate edges, acceptance criteria, assignment constraints, estimates, and rationale. + +The policy must: + +- prefer independently leasable units with explicit deliverables and acceptance; +- retain cross-repository dependencies rather than copy the same task into each repository; +- express fan-out/fan-in, verifier, synthesizer, review, and delivery work as ordinary typed work items; +- avoid decomposing below useful coordination granularity or above configured graph/packet/budget limits; +- preserve user-stated constraints and anchors; +- flag insufficient evidence rather than invent repository, tool, model, assignee, or acceptance facts; +- match executor classes by capabilities, not brand/name popularity; +- identify planned redundant ensemble/review work so duplicate-work policy will not suppress it; +- produce deterministic normalized ordering/digest for the same proposal structure; +- never write, claim, spawn, message, or mutate configuration. + +Application validates the proposal and commits an eligible new plan version in one owner-shard transaction. If autonomous decomposition is disabled, policy returns status/explanation only; it does not create an approval queue. A human may issue direct plan-edit commands. Model assistance is optional, versioned, schema-constrained, evidence-bound, privacy/egress authorized, and evaluated against deterministic baselines. + +Fan-out, verifier, and synthesizer nodes are ordinary `WorkItemVersionV1` values. Their gating edges are staged as one normalized graph mutation; domain validation runs Kahn topological sorting over the active plan plus staged edges before insert and returns the smallest stable cycle witness on failure. No partial child or edge survives a rejected decomposition. Shared state moves only through typed context-packet entries, decisions, handoffs, artifacts, and outcomes; a free-form blackboard comment is not a machine input. + +### 8.2 Readiness and gate evaluation + +`ReadinessPolicyV1` consumes one active work-item version, parent outcomes, gate evidence, schedule, disposition, acceptance prerequisites, scope/workspace state, active lease, executor eligibility, budgets, and explicit clock. It returns one `EffectiveReadinessV1`, all blocking reasons, next transition time, and input manifest. + +Readiness is monotonic only with respect to a frozen plan/evidence snapshot. Later invalidation may move ready work back to blocked before lease. Once leased, a material invalidation creates an attempt revalidation decision: continue, refresh packet, cancel safely, or block. It never silently changes the attempt contract. + +### 8.3 Routing and capability matching + +`RoutingPolicyV1` filters before ranking: + +1. exact authorized scope and workspace mode; +2. executor adapter/host/profile availability and TTL; +3. required tools/effect classes/skills and deny rules; +4. provider/model/reasoning-effort allowlists and privacy residency; +5. context/token/runtime/cost limits; +6. current circuit breakers, rate limits, maintenance/drain state, and capacity; +7. user/policy pinning and fallback constraints. + +Ranking may use role fit, observed quality on comparable work, queue delay, locality, context capacity, cost, deadline risk, diversity policy, and historical reliability. Every feature is versioned/explained. No protected text or unbounded model inference enters a low-cardinality metric. If no route is eligible, return `BlockedByCapability` with exact missing/denied capabilities and recovery actions; never assign a default profile silently. + +### 8.4 Priority, criticality, and fairness + +Scheduling computes a stable score from: + +- explicit priority class and deadline; +- dependency unlock value and critical-path slack; +- wait age/starvation protection; +- initiative/project/user fairness weights; +- executor/provider/model capacity and reservation; +- retry/backoff and circuit-breaker state; +- schedule/time window; +- bounded cost/budget pressure; +- planned ensemble/diversity constraints. + +Use hierarchical weighted fair queues across profile → initiative/project-set → executor/provider → task, with reserved minimum progress for old eligible work. One large initiative cannot starve unrelated projects; one slow/rate-limited profile cannot consume the global queue; cheap tasks do not permanently outrank important expensive tasks. Policy returns component scores, selected/nonselected candidates, and reason codes. The atomic lease-acquisition transaction revalidates the chosen item. + +### 8.5 Retry, backoff, and circuit breakers + +Failure taxonomy: + +- spawn/start failure; +- executor lost/unhealthy; +- transient provider/network/rate limit; +- authentication/authorization denied; +- model/capability/tool unavailable; +- runtime deadline/heartbeat loss; +- workspace dirty/drift/conflict; +- protocol violation/stale lease; +- acceptance failure/reviewer rejection; +- external effect unknown/partial; +- user/system cancellation; +- policy/config/scope invalidation. + +Retry policy selects retry same route, retry alternate allowed route, refresh packet, rebind clean workspace, wait/backoff, require input, return to triage, fail terminally, or quarantine for reconciliation. It consumes per-task/per-initiative/provider budgets and never retries non-idempotent unknown effects blindly. + +Circuit breakers exist by task, executor registration, adapter version, provider/model, credential reference, capability, host, project/worktree, and external effect class. Half-open probes are bounded and visible. A rate-limit breaker does not count as task-quality failure; an auth breaker does not silently select a provider outside the grant. + +### 8.6 Context relevance and sibling materiality + +`ContextPacketPolicyV1` and `TaskMaterialityPolicyV1` reuse Plan 15/23 retrieval quality and Plan 22 novelty/silence semantics. Positive evidence includes direct dependency, shared decision/acceptance, explicit handoff, direct file/symbol/test/PR overlap, plan relation, changed workspace base, new authoritative result, or a matching canonical `query_scope`/query digest under the same resolved scope plus shared goal/anchor evidence. Query overlap remains advisory and requires the registered high-threshold feature combination; temporal proximity, same repository, same title, broad embedding similarity, or copied prompt alone is insufficient. + +Planned redundant research/review/ensemble work is marked and not warned as accidental duplication. When accidental overlap is material, policy emits a bounded candidate only: exact affected attempts/agents, materiality features, safe-summary eligibility, retrieval anchors, and suppression hints. Plan 22's `ScoutDecisionV1` is the sole delivery decider and owns summary/anchor selection (at most one envelope with no more than three anchors), dedupe, and pair/category/anchor cooldown. Policy cannot cancel, reassign, lock, message, or deliver. + +### 8.7 Layered attempt-liveness and sentinel policy + +No single timeout means “dead.” `AttemptLivenessPolicyV1` receives a frozen attempt/lease, monotonic clock, last explicit heartbeat, last accepted provider/tool/Turn activity, executor registration state, optional adapter liveness probe, process evidence when local, runtime budget, cancellation state, breaker state, and effect-reconciliation state. It returns exactly one typed proposal: + +```rust +pub enum AttemptLivenessDecisionV1 { + Healthy, + ExtendAlive { new_expiry: UtcMicros, evidence: LivenessEvidenceRef }, + AwaitProbe { retry_at: UtcMicros }, + RequeueRateLimited { retry_at: UtcMicros, sentinel: RateLimitSentinelV1 }, + RequestCancellation { reason: AttemptStopReasonV1, deadline: UtcMicros }, + FenceAndReconcile { reason: AttemptLossReasonV1 }, + ProtocolViolation { code: ProtocolViolationCodeV1 }, +} + +pub enum TaskLivenessEventClassV1 { + LeaseIssued, + Heartbeat, + AliveExtended, + LeaseExpired, + LeaseFenced, + LeaseRevoked, + AttemptReclaimed, + ReplacementStarted, + Requeued, + ProbePositive, + ProbeNegative, + ProbeUnknown, + ProbeTimeout, + ProbeUnsupported, + RateLimitSentinel, + RateLimitDeferred, + RateLimitRequeued, + ProtocolViolation, + ExecutorCrash, + StaleWriteRejected, + ZombieCompletionRejected, + MaximumRuntimeStop, + HeartbeatBackstopStop, + CancellationRequested, + CancellationTerminal, + ExternalEffectUnknown, + ReconciliationStarted, + ReconciliationTerminal, + TerminalSucceeded, + TerminalFailed, + TerminalCancelled, + TerminalTimedOut, + TerminalLost, + ImportedUnknown, +} + +pub struct RateLimitSentinelV1 { + pub attempt: ExecutionAttemptId, + pub executor: ExecutorRegistrationId, + pub provider: Option, + pub observed_code: RegisteredExitOrProviderCode, + pub retry_after: Option, + pub evidence: RetrievalAnchorId, + pub observed_at: UtcMicros, +} +``` + +Every lease/attempt/probe/sentinel/reconciliation event emitted by application maps to one closed `TaskLivenessEventClassV1` variant in the same transaction. Plan 26 generates an exhaustive variant-to-rollup mapping; it has no wildcard arm, and imported unknown evidence remains the visible `ImportedUnknown` class. + +Baseline plan-20 descriptors and defaults are explicit and versioned: + +| Config key | Default | Rule | +|---|---:|---| +| `scheduler.attempt_liveness.lease_ttl` | `5m` | Authority expires unless a current-epoch CAS extends it; minimum `30s`, maximum `30m`. | +| `scheduler.attempt_liveness.heartbeat_expected` | `60s` | Missing one heartbeat changes visibility only; provider/tool/Turn activity may satisfy liveness through an adapter receipt. | +| `scheduler.attempt_liveness.heartbeat_stale_backstop` | `60m` | A nominally alive worker with no accepted heartbeat or activity by this bound is wedged and enters cancel/reconcile. | +| `scheduler.attempt_liveness.probe_timeout` | `2s` | Probe failure is `Unknown`, not `Dead`; probes are cached/rate-limited and never run in the writer transaction. | +| `scheduler.attempt_liveness.alive_extension` | `2m` | Expired TTL plus positive current probe/activity extends the same epoch, bounded by max runtime; it never reclaims or spawns a duplicate. | +| `scheduler.attempt_liveness.default_max_runtime` | `4h` | Attempt may override within authorized `5m..24h`; reaching it requests cancel, then fences/reconciles after the configured grace. | +| `scheduler.attempt_liveness.cancel_grace` | `30s` | Adapter-specific longer grace must be explicit in its manifest and capped by policy. | +| `scheduler.rate_limit.default_backoff` | `2m` | Used only when no bounded provider `Retry-After` is available. | +| `scheduler.rate_limit.max_backoff` | `1h` | Sentinel requeue cannot exceed the attempt deadline/budget and emits the next exact wake time. | +| `scheduler.repair_poll_interval` | `30s` | Repair fallback for missed journal wakeups/checkpoint gaps, not normal dispatch cadence. | + +Rules, in order: + +1. Current cancellation, terminal state, noncurrent attempt, or epoch mismatch wins and rejects activity. +2. Maximum runtime cannot be extended by heartbeat or PID/process evidence. +3. Positive adapter/activity evidence with an expired TTL returns `ExtendAlive` for the same attempt/epoch; it never mints a replacement lease. +4. A negative authenticated remote probe plus expired TTL may propose fence/reconcile; missing, timed-out, or unsupported probe stays `Unknown` until the heartbeat backstop or other evidence resolves it. +5. Registered rate-limit signals, including POSIX `EX_TEMPFAIL`/75 where the adapter declares that mapping, close the current attempt in terminal state `Deferred` with outcome disposition `deferred`, result `no-op`, and reason `RateLimited`; release capacity safely and requeue a new attempt after backoff without incrementing task-quality/consecutive-failure counters. They neither reset an existing failure breaker nor become success. +6. A worker/process/provider exit reported successful while the attempt lacks a fenced terminal command is a first-occurrence `ProtocolViolation`, not success; it enters reconciliation and the protocol breaker. +7. Crash, timeout, authorization, capability, acceptance, cancellation, rate-limit, and protocol classes maintain separate counters and denominators. Only an accepted successful terminal outcome resets the task consecutive-failure breaker. + +Application re-reads all referenced versions and evidence before applying a proposal. Policy never probes a process, extends a lease, kills a worker, requeues work, or increments counters itself. + +--- + +> **Part B — Scheduler and executor SPI.** Sections 9–10: application use cases, the authoritative scheduler, fenced lease-acquisition/heartbeat workflows, and the executor adapter SPI/many-host protocol (§13.4 secures it; §§17.4/17.6 verify it). + +## 9.

The convenience endpoint accepts/returns the same AST/digest and defines no task-only selector. | +| `work_items.context` | Current or exact-attempt packet view with source/omission/access/expiry status; never assembles with ambient CWD or current board. | +| `work_items.dependencies` | Parents/children/blockers/unblockable/closure/path/cycle witness/critical-path and gate explanations. | +| `attempts.list/get/timeline` | Requested/actual route, lease, packet, workspace, tools, Turns, costs, events, outcome, cancellation/reconciliation, and evidence. | +| `task_offers.list/get` | Registration-scoped open/terminal offers with immutable revision, work/assignment/route/rationale and policy/config/catalog pins, readiness digest, expiry, and legal CAS actions; no lease proof or unrelated queue contents. | +| `context_packets.list/get` | Attempt-scoped sealed packet ordinals, start/accepted/superseded/expired state, effective Turn boundary, omissions, coverage, and anchors. | +| `task_notifications.list/get` | Owner-scoped saved filter/channel/event-class/quiet-hours/dedupe/rate-budget subscriptions with current version and delivery health; never implicit subscriptions or unrelated recipients. | +| `executors.list/get/match` | Registered capability/health/capacity/provider/model/effort/workspace/privacy state and explained eligible/ineligible task matches. `match` is read-only. | +| `scheduler.status/explain` | Queue snapshot, fairness/resource/budget decisions, next wakeups, circuit breakers, coverage, and exact no-action reasons. | +| `task_graph.status/doctor/events` | `status` returns authoritative graph/scheduler/lease/attempt/projector/outbox health; `doctor` performs bounded protected diagnostics without mutation; `events` creates or resumes the canonical authorized task read-model subscription with journal cursor/gap semantics, never a second event stream. | +| `task_views.list/get` | Saved authorized query/lens definitions and current/frozen result manifests; result data is queried, not copied into the view record. | + +Queries use read ports only. They cannot create anchors by mutating during a nominal read unless the caller explicitly requests the durable anchor workflow and receives its operation status. Catch-up ingestion, remote refresh, graph rebuild, and Git fetch are separate explicit capabilities. + +### 9.2 Command use cases + +| Use case | Required command semantics | +|---|---| +| `initiatives.create/update/pause/resume/retire` | Explicit profile owner and declared scope; optimistic version; sanitizer; audit; direct receipt. Retire does not delete history or running effects. | +| `plans.create_version/activate` | Validate normalized graph, versions, scope, cycles, gates, criteria, grants, budgets, active-attempt impact, and evidence. Activation is one owner-shard transaction. | +| `plans.decompose` | Run pure deterministic/model-assisted policy and autonomously commit an eligible version within enabled authority. Returns version/decision/receipt, not a preview/apply proposal queue. | +| `work_items.create/update/replace/retire` | New typed version, exact plan membership, expected versions, relation/acceptance validation, and affected-attempt decision. | +| `work_items.link/unlink` | Gating versus non-gating kind explicit; cycle and active-plan checks; graph version receipt. | +| `work_items.assign/reassign` | Target and route constraints explicit; revalidate executor eligibility; never kill/steal an active attempt implicitly. | +| `work_items.assign_set` | Bounded all-or-none assignment of distinct work-item versions under one plan/owner shard to explicit route constraints. CAS-check plan plus every item/assignment version, validate every provider/model/effort/tool/budget constraint before writing, refuse active-lease theft, and return one transaction receipt with deterministic per-item results. Cross-owner input is rejected rather than partially applied. | +| `work_items.pause/resume/cancel/archive` | Closed lifecycle transitions; cancellation starts a durable workflow and archive retires presentation/lifecycle state without deleting history. | +| `work_items.record_attestation` | Direct optimistic command for an inherently human acceptance criterion. Require criterion/work-item/plan versions, actor role plus grant, typed attestation, sanitized evidence anchors, event time, and `IdempotencyKeyV1`; it cannot satisfy an automated or review-class criterion. | +| `work_items.record_review` | Direct optimistic reviewer decision over one criterion/deliverable version. Require declared reviewer class, selected registered value, evidence, actor/grant, expected versions, and audit receipt; rejection/changes-required stays explicit. | +| `work_items.record_decision` | Append a versioned `TaskDecisionV1` with alternatives, selected value, validity, affected work items, actor/policy, and evidence. Supersession names the prior decision and revalidates affected gates/packets/attempts in the same command transaction. | +| `work_items.record_exception` | Separately authorized exception to exact required criteria, with bounded reason, evidence, actor/grant, affected versions, expiry/review requirement, and permanent outcome-quality visibility; never a generic completion bypass. | +| `work_items.handoff` | Publish one structured `HandoffV1` from the current fenced attempt or an explicitly authorized human transition, pinning completed acceptance, unresolved risks, decisions, artifacts, anchors, suggested next work, and source version/epoch. | +| `work_items.reopen` | Create a new work-item version and readiness path from a terminal/retired item under exact expected versions and reason; never reopen or mutate a terminal attempt. | +| `work_items.reverse_transition` | Reference one reversible prior command receipt/event and append the registered legal inverse as a new version/event under current-version CAS. Never erase history, call rollback, compensate an external effect implicitly, or cross an irreversible/consequential-effect boundary. | +| `attempts.heartbeat/progress/complete/block` | Executor-only lifecycle subset requiring registration, current lease epoch, attempt/work-item versions, exact accepted packet ref, capability-grant-set ID/digest pair, idempotency, and typed evidence. These commands operate only after `task_offers.accept` has atomically issued the attempt/lease/start manifest; none can mint execution authority or update advisory `WorkClaimV1`. | +| `task_offers.accept/decline/revoke` | Executor accept atomically validates the open offer/readiness and delegates to the one lease-acquisition transaction, returning `TaskStartManifestV1`; decline records a bounded reason and releases no authority because none existed; scheduler/admin revoke is versioned and idempotent. Expiry is an internal canonical event. | +| `context_packets.accept` | Fenced executor command over a higher sealed packet ordinal and explicit safe Turn boundary; update only the attempt's monotonic accepted-packet pointer/event and never widen route/workspace/grants/access/budget. | +| `work_items.retry` | New attempt under retry policy/budget; never mutates prior attempt; unknown effects reconcile first. | +| `executors.register/heartbeat/drain/unregister` | Authenticated adapter/host manifest and TTL; drain stops new leases but preserves existing recovery. | +| `scheduler.pause/resume/run_once` | Scoped operational control with receipts. `run_once` reuses the same scheduler path and cannot bypass policy or concurrency. | +| `task_views.create/update/delete`, `task_views.share.plan`, `task_views.share.start`, `task_views.share.revoke` | Direct create/update/delete preserve the protected canonical `TraceQueryV1`/lens with mandatory `query.scope`, ownership, grouping/layout/snapshot/version/watermark, and no result-row copy or second scope selector. Share plan computes classification/redaction/expiry and a confirmation digest without disclosure; start creates the exact authorized expiring bundle; revoke invalidates its grant/version and active subscriptions without deleting the owner view. | +| `task_notifications.create/update/delete` | Direct validated subscription command with expected version/idempotency over saved filter, channel, event classes, quiet hours, dedupe and rate budget. No generic preview/apply pair and no implicit subscription on task creation. | + +The seven manual-work commands have distinct generated input schemas but share exact work-item/plan expected versions, actor/grant, `IdempotencyKeyV1`, sanitizer/evidence refs, policy/config/catalog pins, and a canonical event/receipt. Their stable catalog IDs are exactly `work_items.record_attestation`, `work_items.record_review`, `work_items.record_decision`, `work_items.record_exception`, `work_items.handoff`, `work_items.reopen`, and `work_items.reverse_transition`; transports may map naming style but may not merge them into a generic mutation. + +Ordinary task/plan mutations commit directly after validation. Destructive external consequences—worktree deletion, force-affecting Git operation, PR merge, deployment, release, protected-data deletion—remain separate plan-09 commands with explicit confirmation/authorization and receipts. They are never hidden inside `attempts.complete` or inferred from work-item readiness. + +### 9.3 Scheduler tick + +The scheduler is an application worker consuming canonical `task_graph_events` journal ranges plus registered exact-time wakeups. The outbox carries only post-commit wakeup/external-effect delivery intents that reference those journal events; the scheduler never treats outbox delivery state as task truth. It does not scan every project database or board. Committed owner-shard mutations signal an in-process/cross-process notifier only after commit; the notifier carries a sequence range, never task payload or authority. The scheduler drains from its durable journal checkpoint, so a lost/coalesced notifier or outbox wakeup loses latency but not work. A plan-20 `scheduler.repair_poll_interval=30s` fallback compares the journal high watermark, scheduled-wakeup heap, lease deadlines, and checkpoint only when no notification arrived or a gap is detected; it never becomes Hermes's ambient 60-second board scan. + +Latency gates at the reference corpus are: commit-to-eligible scheduler observation p95 ≤ `1s`, terminal/cancellation safety event observation p95 ≤ `250ms`, eligible-to-offer p95 ≤ `2s` when capacity is available, dashboard subscription delta p95 ≤ `1s`, and missed-notification recovery ≤ one `30s` repair interval. Benchmarks inject dropped/coalesced notifier messages to prove the durable journal is authoritative. Hermes's historical 60 s dispatcher, 5 s notifier, and 300 ms dashboard polls remain comparison fixtures, not V2 constants. + +One tick: + +1. renew the scheduler's own fenced lifecycle lease and capture clock/config/catalog/policy generations; +2. consume dependency, schedule, executor, budget, workspace, cancellation, and attempt events since checkpoint; +3. ask projectors for bounded current candidates and stale/reconciliation work; +4. evaluate pure readiness, retry, circuit-breaker, routing, and fairness policy on frozen inputs; +5. prioritize cancellation/reconciliation/lease-expiry safety before considering new offers; +6. for each selected candidate, freeze the work-item/plan/readiness, executor, proposed assignment/route, rationale evaluation, policy manifest, effective config snapshot/digest, and catalog snapshot; the scheduler does not create a workspace, packet, grant set, attempt, lease, reservation, or start intent; +7. open one short bounded owner-shard transaction, revalidate every frozen candidate, and for each still-eligible selection insert exactly one `Open` `TaskOfferV1` plus its proposed assignment/routing-decision evidence, canonical offer event, delivery outbox row, and idempotency result; +8. inside that same transaction, record all selected and material nonselected decision reasons, advance the consumed journal checkpoint, and register the next exact offer-expiry/schedule/backoff/lease/probe wakeup; +9. after commit, deliver the same persisted offer to a push adapter or leave it available to the executor-scoped pull query; delivery success never creates execution authority. + +No tick holds the DB writer while resolving Git, querying a model, spawning a process, calling a remote adapter, or assembling a large packet. No scheduler tick builds a start packet or invokes an executor. Decomposition/model planning runs as a separately budgeted workflow before the item becomes an offer candidate. + +Backpressure: + +- bounded candidate/offer scheduler batches and separately bounded acceptance packet/start, cancellation, and reconciliation workflows; +- hierarchical concurrency and rate limits by profile/initiative/project/executor/provider/model/host/effect; +- coalesce repeated readiness events by work-item/version while preserving terminal/cancellation evidence; +- shed optional estimate/materiality recomputation before safety/recovery work; +- expose queue age and skipped reason rather than silently cap; +- use exact next schedule/backoff/lease expiry rather than idle polling where possible. + +### 9.4 Lease acquisition and start handshake + +The scheduler persists one canonical offer. A push-capable adapter receives only that offer through `TaskExecutorAdapterPort::offer`; a pull executor reads its own offers through `task_offers.list`. Both accept through the same authenticated `task_offers.accept` application command, which delegates atomically to lease acquisition: + +```rust +pub struct AcquireTaskLeaseCommandV1 { + pub work_item: WorkItemVersionRefV1, + pub executor: ExecutorRegistrationId, + pub offer: TaskOfferId, + pub expected_offer_revision: u64, + pub expected_work_item_revision: u64, + pub expected_plan_version: PlanVersionId, + pub expected_readiness_digest: ManifestDigest, + pub idempotency_key: IdempotencyKeyV1, +} + +pub struct TaskStartManifestV1 { + pub accepted_offer: TaskOfferId, + pub accepted_offer_revision: u64, + pub attempt: ExecutionAttemptId, + pub lease: TaskLeaseId, + pub lease_proof: Protected, + pub fence_epoch: u64, + pub work_item: WorkItemVersionRefV1, + pub plan_version: PlanVersionId, + pub assignment: AssignmentId, + pub route: ExecutorRouteV1, + pub workspace: WorkspaceBindingId, + pub context_packet: ContextPacketManifestRefV1, + pub capability_grant_set_id: CapabilityGrantSetId, + pub capability_grant_set_digest: ManifestDigest, + pub policy_manifest: PolicyManifestRef, + pub effective_config_snapshot_id: EffectiveConfigSnapshotId, + pub effective_config_digest: EffectiveConfigDigest, + pub catalog_snapshot: CatalogSnapshotRefV1, + pub deadlines: AttemptDeadlinesV1, + pub budget: AttemptBudgetV1, + pub manifest_digest: ManifestDigest, +} +``` + +An offer is not a lease and expires harmlessly. Only `TaskStartManifestV1` authorizes start; its `accepted_offer_revision` is the post-CAS accepted revision and its receipt names the accepted event. Adapter acknowledgement records actual route/runtime before attempt becomes `Running`. Start timeout enters reconciliation; it does not immediately issue a second live lease. + +```rust +pub struct TaskOfferV1 { + pub id: TaskOfferId, + pub revision: u64, + pub work_item: WorkItemVersionRefV1, + pub offered_work_item_revision: u64, + pub plan_version: PlanVersionId, + pub executor: ExecutorRegistrationId, + pub offered_assignment: AssignmentId, + pub offered_route: ExecutorRouteV1, + pub rationale_evaluation: PolicyEvaluationId, + pub rationale: PolicyExplanationRef, + pub offered_readiness_digest: ManifestDigest, + pub policy_manifest: PolicyManifestRef, + pub effective_config_snapshot_id: EffectiveConfigSnapshotId, + pub effective_config_digest: EffectiveConfigDigest, + pub catalog_snapshot: CatalogSnapshotRefV1, + pub issued_at: UtcMicros, + pub expires_at: UtcMicros, + pub state: TaskOfferStateV1, // Open | Accepted | Declined | Expired | Revoked +} +``` + +`task_offers` (activity owner shard) stores `(offer_id PRIMARY KEY, revision, work_item_id, work_item_version_id, offered_work_item_revision, plan_version_id, executor_registration_id, offered_assignment_id, offered_route_ref, rationale_evaluation_id, rationale_ref, offered_readiness_digest, policy_manifest_ref, effective_config_snapshot_id, effective_config_digest, catalog_generation, catalog_digest, issued_at, expires_at, state, terminal_event_id NULL)`, with at most one `Open` offer per `(work_item_id, executor_registration_id)` (partial unique index) and an expiry index on `(state, expires_at)`. Every state change appends an immutable lifecycle event and advances the current projection's `revision`; work/plan revisions, assignment, route, rationale/evaluation, readiness, policy/config/catalog pins, addressee, and expiry never change behind an offer ID. Terminal rows may compact only to a durable tombstone retaining those pins and event refs. An offer carries the `readiness_digest` observed at offer time; the executor echoes it as `expected_readiness_digest`, so an offer raced by a graph change fails lease acquisition instead of starting stale work. + +`offered_assignment_id` is preallocated identity, not an assignment row or authority. The offer stores the complete proposed target/route/rationale pins. Only acceptance inserts `task_assignments(assignment_id=offered_assignment_id, source_offer_id=offer_id, state=Active)` in the same transaction as attempt/lease/grants/reservations; decline/revoke/expiry leaves no assignment row. + +`task_offers.accept`, `task_offers.decline`, and `task_offers.revoke` all require `offer`, `expected_offer_revision`, and `IdempotencyKeyV1`. Accept additionally requires registration identity, exact work-item/plan versions, and echoed readiness digest; decline records one registered safe reason; revoke is scheduler/admin-only. A losing CAS returns the current safe offer view and writes no lifecycle event. Expiry is a deterministic internal CAS. Push delivery acknowledgement is not acceptance or authority. The pull query exposes only offers addressed to the authenticated registration, and push/pull conformance proves the same offer cannot yield two attempts. + +Acceptance is an application workflow, never scheduler-side dispatch. Before its final transaction it resolves/creates the exact safe workspace binding, assembles the sealed packet, calculates the immutable grant set, and preallocates all IDs against the offer's frozen pins without publishing any authority. The final transaction described in §5.3 changes `Open → Accepted` and atomically creates the assignment activation, packet, attempt, lease, grant set, reservations, `TaskStartManifestV1`, canonical events, and adapter-start intent. If preparation, expiry, authorization, or any CAS fails, the offer remains open or reaches its independently justified terminal state and no packet/attempt/lease/start exists. + +Lease acquisition is a CAS over the expected work-item revision, plan version, readiness digest (the transactionally maintained `work_items.readiness_digest` column of §5.3, never a projection read), active lease, executor capacity, budget, workspace generation, and writable-resource reservation set. Application derives the attempt's writable artifacts/resources from scope, workspace, grants, and acceptance, then checks active task leases and evidence-backed work claims for overlapping worktree/branch/file/symbol/test/artifact targets **plus** `WorkClaimScopeV1.query_scope` identity/digest, resolved scope, shared retrieval anchors, and explicit goal evidence. Query/goal similarity is advisory and thresholded; a direct authoritative resource reservation blocks, while a query-only overlap triggers materiality review and cannot steal authority. `DeliberateEnsemble`, diverse review, planned parallel, and read-only relations suppress accidental-duplication warnings and are recorded in the start manifest. + +### 9.5 Heartbeat and progress + +Heartbeat is a small constant-cost CAS. It validates executor, attempt, lease/epoch, monotonic sequence (the lease's `heartbeat_sequence`, which every heartbeat must strictly increase), expiry grace, and cancellation state, then appends or coalesces a safe liveness event. Heartbeat cannot change task spec, plan, route, tools, workspace, packet, acceptance, or budget. + +Accepted provider/Turn/tool activity may invoke the same application-owned heartbeat bridge with a source event ref; adapters cannot mutate the lease directly. The bridge deduplicates by source observation and never extends beyond the attempt maximum runtime. Expired TTL with authenticated positive liveness follows §8.7 `ExtendAlive` on the same epoch. Negative/unknown probes never reclaim inside this command. A noncurrent attempt or stale epoch receives a stable stale-attempt problem and a bounded protocol event; repeated zombie traffic is coalesced by `(attempt, epoch, code, window)` so it cannot flood the journal. + +Progress is optional structured telemetry with phase, bounded safe status, completed/total units, current artifact/tool refs, cost delta, and next checkpoint. It is sampled/coalesced for dashboards and cannot substitute for artifacts or acceptance. Raw worker logs use the protected log stream. + +### 9.6 Completion and blocking protocol + +`CompleteAttemptCommandV1` requires: + +- current attempt/lease/epoch/executor/work-item/plan versions; +- terminal handoff with safe summary and residual risks; +- artifact refs and provenance; +- acceptance evidence/evaluations or authorized exception refs; +- actual executor route and tool/catalog/skill receipts; +- measured/unknown cost components; +- external effect receipts/reconciliation state; +- optional follow-up work descriptors that application validates before creating new work; +- stable idempotency key. + +Application revalidates and atomically closes attempt, lease, reservations, outcome, handoff, and dependent events. A successful provider/process exit without this command becomes `ProtocolViolation`; policy decides whether to retry, block, or fail. + +Completion revokes the lease proof/grants/credentials, releases writable-resource reservations, and closes any executor-owned advisory work claim in the same canonical outcome sequence. Cancellation fences/revokes them before a replacement attempt can commit. A process, provider session, or worker that remains alive after manual completion/cancellation is stale: every later canonical heartbeat, artifact, brokered tool effect, and terminal write is rejected by proof/epoch/version checks. An already-issued unmediated/non-preemptible external effect is quarantined as effect-unknown and blocks replacement on the affected resource until stop/reconciliation; it is never falsely described as rejected. + +`BlockAttemptCommandV1` uses typed classes: dependency, decision/input, capability, authorization, workspace/conflict, transient provider, external-effect unknown, acceptance/review, budget, or other registered safe reason. Dependency blocks create explicit gating evidence rather than a human-notification loop. Repeated same-cause unblock/reblock feeds a loop breaker and may return the task to triage. + +### 9.7 Cancellation and stale recovery + +Cancellation workflow: + +1. record request, actor/reason/scope, expected versions, and whether descendants/effects are included; +2. move attempt to `CancellationRequested` and stop issuing new grants/effects; +3. send adapter cancellation with attempt/lease epoch and deadline; +4. collect acknowledgement, provider/process/tool stop receipts, and last known external effects; +5. reconcile workspace/Git/PR/message effects and artifacts; +6. revoke/fence lease and release reservations only at the safe boundary; +7. emit `Cancelled`, `Failed`, or `EffectUnknown` terminal outcome; +8. recompute dependent gates and plan impact. + +Cancellation of a plan/initiative is a bounded descendant workflow, not a broad SQL status update. Already terminal work remains historical. Shared work items require explicit membership/ownership analysis before cancellation. + +Stale lease recovery uses heartbeat TTL plus adapter/host/session/provider evidence. Local PID death may strengthen `Lost`; remote absence/timeout alone remains uncertain. The old epoch is fenced before a new lease, but non-idempotent effects remain blocked until reconciliation proves safe. + +Recovery executes §8.7's decision transactionally: `ExtendAlive` preserves the attempt and epoch; `RequeueRateLimited` records a non-failure deferred terminal attempt and exact retry wakeup; cancellation first fences new grants/effects and observes the adapter grace; `FenceAndReconcile` increments `next_fence_epoch` before any replacement claim. A zombie completion after supersession is never silently discarded: application returns stale-attempt, appends/coalesces `ZombieAttemptProtocolViolation`, and leaves current attempt, breaker, outcome, and dependencies unchanged. + +### 9.8 Workspace, branch, commit, and PR workflows + +Workspace preparation: + +- resolve the exact `ScopeResolutionV2`, repository, checkout, worktree, ref, base commit, and indexed snapshot; +- verify ownership/dirty state and active agents/leases; +- choose configured existing-read-only, owned-existing-write, new isolated worktree, remote workspace, or sandbox mode; +- reserve unique worktree/branch identity through the application service; +- create/adopt through a consumer-owned `WorkspacePort` after durable intent; +- capture resulting Git/worktree observation and verify it matches the binding; +- seal the binding before packet/lease issuance. + +During execution, capture file/tool/Git events and correlate them to attempt/lease/workspace. A branch, commit, or PR is not required unless acceptance says so. When produced: + +- record immutable commit/ref/PR/check identities and live/local freshness separately; +- block on base drift/conflict when acceptance or grant requires current base; +- never infer PR ownership from merely viewing it; +- require a delivery-task grant for push/open/update/review/merge/release; +- use separate verifier/reviewer work items for aggregate or high-risk changes; +- preserve failed/dirty worktrees for investigation under retention policy; +- clean only TraceDecay-owned disposable workspaces after terminal/reconciled state and no references. + +### 9.9 Human and autonomous boundaries + +Authorized humans may directly create/version/assign/pause/cancel/archive work, invoke `work_items.record_attestation`, `work_items.record_review`, `work_items.record_decision`, `work_items.record_exception`, `work_items.handoff`, `work_items.reopen`, or `work_items.reverse_transition`, change priority/budgets, and operate the scheduler. Every command is optimistic, audited, scope-bound, and writes a new version/event/receipt directly; none enters a preview/apply or generic rollback queue. + +Autonomous components may, only within activated plan-20 authority: + +- decompose/activate plan revisions; +- route/reassign eligible work; +- issue/revoke leases; +- assemble packets; +- retry/back off/circuit break; +- create validated follow-up/remediation work; +- stop unsafe attempts; +- apply autonomous curation effects owned by the curation system. + +Models and executor workers propose; application authorizes. The scheduler cannot widen grants, scope, egress, budgets, model set, or destructive effects. Plan 22 is advisory only. Autonomous curation does not wait for per-item review, and task review gates never become a backdoor curation approval queue. + +## 10. Executor adapter SPI and many-host protocol + +### 10.1 Consumer-owned SPI + +Application owns the port; root composition owns concrete adapters: + +```rust +pub enum ExecutorOfferDeliveryActionV1 { Offer, Revoke } +pub enum ExecutorOfferDeliveryDispositionV1 { Delivered, AlreadyCurrent, Rejected, Unavailable, Unknown } + +pub struct ExecutorOfferDeliveryReceiptV1 { + pub offer_id: TaskOfferId, + pub offer_revision: u64, + pub executor_registration_id: ExecutorRegistrationId, + pub action: ExecutorOfferDeliveryActionV1, + pub disposition: ExecutorOfferDeliveryDispositionV1, + pub adapter_receipt_digest: ManifestDigest, + pub observed_at: UtcMicros, +} + +pub trait TaskExecutorAdapterPort: Send + Sync { + fn capabilities<'a>( + &'a self, + registration: ExecutorRegistrationId, + ) -> BoxFuture<'a, Result>; + + fn offer<'a>( + &'a self, + offer: TaskOfferV1, + ) -> BoxFuture<'a, Result>; + + fn revoke_offer<'a>( + &'a self, + offer: TaskOfferId, + ) -> BoxFuture<'a, Result>; + + fn start<'a>( + &'a self, + manifest: TaskStartManifestV1, + ) -> BoxFuture<'a, Result>; + + fn status<'a>( + &'a self, + attempt: ExecutionAttemptId, + fence_epoch: u64, + ) -> BoxFuture<'a, Result>; + + fn cancel<'a>( + &'a self, + request: ExecutorCancelRequestV1, + ) -> BoxFuture<'a, Result>; + + fn collect<'a>( + &'a self, + attempt: ExecutionAttemptId, + since: ExecutorEventCursorV1, + ) -> BoxFuture<'a, Result>; +} +``` + +The SPI uses generated versioned wire schemas over local IPC/HTTP/stdio as appropriate. `offer`/`revoke_offer` are advisory delivery only: their receipts mean delivered/unsupported/declined-at-transport, never accepted or leased; canonical acceptance still enters through the application command. Pull-only adapters declare push unsupported and poll their registration-scoped offer query. No unstable Rust dynamic-library ABI. Custom adapters use the versioned external protocol/WIT-like contract and conformance suite. Adapter-specific native fields live in protected typed extension schemas and never leak into canonical lifecycle logic. + +### 10.2 Registration and host handshake + +Registration proves adapter/host identity using loopback credentials, mTLS, OS peer credentials, or configured service identity according to deployment. It advertises protocol version, adapter version, executor class, supported provider/model/effort, context/tool limits, workspace modes, process/cancellation semantics, event streaming, residency, concurrency, and current health. + +Application returns accepted capability subset, config/catalog generations, heartbeat TTL, maximum offer count, authorized scope classes, and drain/update state. Registration cannot self-authorize. Capability changes create a new manifest generation; active attempts remain pinned or are explicitly revalidated. + +Executor registrations are host/runtime instances, not durable personas. Actor/agent/profile identity remains separate. One profile may expose several executor registrations; one registration may start many agent/session attempts under its cap. + +### 10.3 Built-in adapter requirements + +| Adapter | Required exact capture and control | +|---|---| +| Codex | Thread/session/Turn/goal/plan updates, subagents, tool calls/results, reasoning artifacts exposed by provider, worktree/CWD, model/effort, cancellation acknowledgement, token/cost receipts, host capability generation. | +| Claude | Session/workflow/agent/subagent/hook/tool events, model/effort where supported, workspace, permissions/tool grants, cancellation, usage/cost, provider-native identifiers. | +| Cursor | Composer/agent/session/tool events available from host, worktree/CWD, selected model/effort if exposed, background/remote lifecycle, cancellation and incomplete-coverage status. | +| Hermes | Profile/session/Turn/tools/skills, provider/model/fallback, workspace, task lifecycle, goal mode where used, cancellation/logs/cost; no shared Kanban DB authority. | +| Custom | Versioned conformance protocol, explicit capabilities/residency/effects, stable event cursors, start/status/cancel/collect, and no implicit shell/database contract. | + +Provider coverage is truthful. If a host cannot expose an exact Turn, actual model, effort, tool event, cancellation receipt, or usage, the field is `Unavailable(reason)` and related claims remain partial. No adapter synthesizes fake native IDs. + +Hermes reconciliation (cited by master §2.6 row #407): TraceDecay gives Hermes exactly two V2 roles. First, during migration, Hermes is a capture source and import-evidence provider — under merged PR #407's user-profile consolidation, its transcripts and historical Kanban stores are read as external evidence sources feeding the §16 import rules and the plan 13 evidence registry. Second, at execution time, Hermes is one executor adapter behind the §10.1 SPI, registered, fenced, and receipted exactly like Codex, Claude, Cursor, and custom adapters. The Hermes executor adapter is a new SPI implementation: it does not revive or depend on the bridges/config/inventory that #407 removed, and enabling it requires #407's accepted consolidation ledger. In neither role does Hermes own tasks — there is never a parallel Hermes task-owning silo, shared Kanban DB authority, or Hermes-side scheduler for canonical work. + +### 10.4 Worker start and prompt/tool contract + +Adapter receives references/manifests, then hydrates only authorized packet entries and tool schemas through the application service. The worker system/task context includes: + +- canonical initiative/plan/work-item/attempt/lease refs and safe labels; +- objective/specification, constraints, acceptance, dependency state, packet entries, and omissions; +- exact workspace binding and permitted repository operations; +- lifecycle protocol: heartbeat, progress, block, complete, cancellation response; +- loaded skill versions and capability/tool grant-set ID/digest pair; +- budget/deadline and packet refresh rules; +- instruction to treat retrieved text as evidence, never authority to widen scope/tools; +- prohibition on hidden reasoning disclosure and unrelated sibling/global task inspection. + +The lifecycle toolset is stable and small. Other task-specific tools are granted from the catalog. An executor with a remote terminal still reports lifecycle through the host/application channel; it never shells out to a TraceDecay CLI inside an arbitrary container or mounts the profile store. + +### 10.5 Capability grant model + +```rust +pub struct CapabilityGrantV1 { + pub grant_id: CapabilityGrantId, + pub grant_set_id: CapabilityGrantSetId, + pub capability: CapabilityId, + pub effect: EffectClassV1, + pub allowed_scope: ScopeResolutionId, + pub resource_constraints: ResourceConstraintV1, + pub egress: EgressGrantV1, + pub credential_ref: Option, + pub issued_to: ExecutorRegistrationId, + pub attempt: ExecutionAttemptId, + pub lease: TaskLeaseId, + pub lease_epoch: u64, + pub revocation_epoch: u64, + pub issued_at: UtcMicros, + pub expires_at: UtcMicros, + pub catalog_snapshot: CatalogSnapshotRefV1, + pub grant_digest: ManifestDigest, +} +``` + +Grant calculation intersects safe floors, actor/initiative/project/repository/worktree policy, executor capability, provider/model policy, task requirements, and request-specific restrictions. Explicit denies and privacy floors win. Grants are attempt/lease-bound, revocable, and expire. Every broker invocation CAS-checks the current grant/lease/revocation epoch. Credentials remain opaque short-lived references resolved only by the authorized effect broker at the moment of use; cancellation/terminal/fence revokes or rotates them before replacement. They never enter packets, logs, events, prompts, tool output, process environments, or reusable provider configuration. + +Required distinct effect classes include read local, read protected, read remote, write workspace files, execute process, mutate Git worktree, mutate remote Git/delivery, external message, configuration, automation, curation, secret access, and administrative/destructive. A task can request a class but cannot grant it to itself. + +Consequential effects are host-mediated, not trusted merely because an adapter once received a start manifest. Remote Git/delivery/message/provider calls and privileged local operations go through an application-owned effect broker carrying `TaskLeaseProofV1`, capability-grant-set ID/digest, `grant_id`, revocation epoch, canonical scope/resource, `IdempotencyKeyV1`, and preconditions on every call. The broker rejects any grant whose set does not match the current attempt and lease. Local agent processes run in a per-attempt process group and scoped workspace namespace with no inherited broad credentials. Where a provider/runtime cannot broker or revoke a write after start, its manifest declares that effect `NonPreemptible`; cancellation fences canonical writes immediately, quarantines that workspace/effect, attempts process-group termination/reconciliation, and forbids a replacement writer until stop or an explicit effect-unknown resolution is durable. TraceDecay therefore never promises to reject an unmediated byte already issued outside its boundary. + +### 10.6 Tool and side-effect idempotency + +Every consequential tool call records invocation, attempt/lease/revocation epoch, capability-grant-set ID/digest, capability/grant, scope, idempotency key, request digest, result/effect receipt, external correlation ID, and reconciliation state. Broker denial after fence is a typed stale-effect event. Adapter reconnect replays events by cursor and deduplicates canonical ingestion. + +TraceDecay does not claim exactly-once external execution. It guarantees at-most-one active canonical lease, idempotent command/result recording, and explicit external-effect reconciliation. Provider/GitHub APIs with native idempotency keys use them. File/Git operations record preconditions and before/after identities.

There is no `/task-events` route or second task SSE protocol. Clients create an authorized canonical `TraceQueryV1` subscription whose task read-model variants emit snapshot/delta/gap/heartbeat with journal sequence, scope/auth digest, graph versions, and reconnect cursor. Slow clients receive a gap/resync directive, not unbounded buffering. + +The kebab-case manual-work route suffixes map bijectively to the seven underscore catalog IDs above. In particular, `:reverse-transition` is a new-version inverse command; there is no `rollback`, `undo`, `preview`, or `apply` task route. + +`scheduler.explain` and `task_graph.doctor` are read-shaped POSTs because their protected scope/evidence bodies do not belong in URLs. `task_graph.events` binds only to a canonical task read-model subscription; no `/task-events` route exists. Plan 08 generates a bijection test over every capability above and its CLI, MCP, HTTP operation, Rust/TypeScript/Python SDK method, application use case, auth/effect metadata, and view/problem type. A missing or extra binding, including scheduler explain/status/doctor/events or any work-item mutation, blocks release. + +Plan 17 generates Rust/TypeScript/Python clients and examples for human orchestration, read-only monitoring, and custom executor adapters.

Offer, packet, and notification deep links resolve the exact canonical ID through their application output module, preserve scope/watermark/selection in a typed link descriptor, reauthorize on open, and render terminal tombstone or denied/unavailable state explicitly. They never emulate detail by filtering a list, use an ambient current board/project, or place lease proofs, private packet payload, channel credentials, or raw routing rationale in the URL. Plan 08/10/17/21 generate operation links to these same owned routes; transports and feature components do not register aliases. + +Global scope tree shows All → profile → initiative/project-set → project → repository → worktree/ref without making navigation state authoritative. Selection is a canonical entity set plus frozen/live watermark shared across lenses. + +### 12.2 Initiative and plan workspace + +Initiative overview contains: + +- objective, exact scope, current plan/version, budgets, deadline, health, progress, outcome, cost, and coverage; +- milestone/fan-in strip and critical-path interval; +- repository/project/worktree participation matrix; +- active agents/executors/attempts and blocked decisions; +- recent consequential events and material handoffs; +- links to related Goals, workflows, PRs/checks/releases, memories/skills, and research anchors; +- plan-version timeline/diff and affected active attempts. + +Plan outline is a hierarchical graph-of-graphs: work item may expand into a child plan; compact rows show readiness, assignment/route, acceptance, dependency, estimate, actual runtime/cost, and evidence. Users can switch to DAG without losing selection/filters/time. + +### 12.3 Kanban/board projection + +Kanban columns derive from `EffectiveReadinessV1`/resolution and are labeled with exact reason semantics. Dragging does not arbitrarily set a status: + +- triage → direct version/plan activation command; +- dependency-blocked cannot be dragged ready without satisfying/removing gates; +- ready → pause/priority/assignment operations, not fake claim; +- running → cancel/reassign only through safe workflow; +- review → explicit `work_items.record_attestation`, `work_items.record_review`, `work_items.record_decision`, `work_items.record_exception`, or `work_items.handoff` when its criterion and grant allow it; +- terminal → `work_items.reopen` creates a new work-item version/readiness path; `work_items.reverse_transition` appends only a registered legal inverse and never rewinds history or external effects; +- archive is presentation/lifecycle retirement, not deletion. + +Board selector is a saved-view query. There is no persisted global current board and no all-board dispatcher. Cross-project writes display the exact initiative/scope and require authorization. + +Saved views may overlap deliberately. A user can keep `Initiative: runtime change — All`, `Rspack`, `Rsbuild`, `React Router plugin`, `Codex queue`, `Claude queue`, `Integration fan-in`, and `My blocked work` open at once; each stores only a versioned `TraceQueryV1`, presentation/grouping, and authorization policy. Moving an item between lanes changes canonical work only through the legal command named above; adding/removing a saved-view filter changes no task, dependency, route, claim, or subscription. One work item can therefore appear simultaneously on a repository board, a provider workload board, and the initiative DAG without copies or competing status. + +### 12.4 DAG, critical path, timeline, and causal lenses + +- **DAG:** legal gating edges, fan-in/out, gate expressions, cycle witness, collapsed subplans, semantic zoom, table fallback. +- **Critical path:** expected ranges, slack, unknown segments, observed versus estimated duration, deadline risk, route/capacity assumptions. +- **Timeline:** plan versions, assignments, leases, attempts, executor/provider changes, packet versions, tools, artifacts, commits/PR/checks, cancellation/retry, costs, and outcomes on one bitemporal axis. +- **Causal:** only evidence-backed causation/production/impact edges; temporal associations appear visually distinct and never as causal arrows. +- **Compare:** align two plan versions, attempts, executors, routes, or time snapshots and retain exact selection/anchor provenance. + +### 12.5 Workload, executor, repository, and All lenses + +- **Workload:** queue/running/blocked/review/terminal counts, age, deadlines, criticality, cost, fairness, and capacity by initiative/project/agent/executor/provider/model/effort. +- **Executor Fleet:** registrations, hosts, capabilities, residency, concurrency, queue, success/retry/cancel/lost rates, p50/p95 runtime/cost, circuit breakers, drain/update state, and current attempts. +- **Repository Work:** work items/attempts/artifacts by exact repository/worktree/ref/commit/PR/check; produced/observed/encountered and local/live freshness remain separate. +- **All:** content-free/lazy rollups first, authorized task hydration on expansion, explicit partial/unavailable shards, and no N-project eager fan-out. + +Every graph has list/table/matrix parity, keyboard navigation, focus/selection synchronization, and deterministic export. Dense views use server-side bounded neighborhood/aggregation and worker rendering; no hairball or browser-side full graph load. + +Workload and DAG lenses include a **claim-overlap** overlay: authoritative writable-resource reservations, advisory work-claim overlap, planned-parallel markers, exact worktree/branch/file/symbol/test/artifact evidence, TTL/heartbeat age, and conflict/materiality reason. It never renders temporal proximity as a lock or exposes another agent's private prompt. + +### 12.6 Task and attempt inspectors + +Task inspector tabs: + +- Overview/specification/constraints; +- Dependencies/gates/critical path; +- Acceptance/evaluations/exceptions; +- Assignments/eligible executors/routing explanation; +- Attempts/retries/cancellation; +- Context packets and omissions; +- Decisions/handoffs/artifacts/outcomes; +- Thread/session/Turn/agent/goal/tool evidence; +- Code/Git/delivery impact; +- Costs/budgets; +- Audit/provenance/anchors. + +These tabs are values of the extended `inspector.tab` union in plan 11's `InvestigationStateV1`; plan 11 owns that union, and this plan defines no parallel tab-state model. + +Attempt inspector shows requested versus actual adapter/provider/model/effort/tools/skills, lease epoch/status without exposing secret material, exact workspace binding, packet version, Turn/tool/artifact timeline, progress/log access, cost, acceptance, cancellation/reconciliation, and residual risk. + +Consequential controls come from generated `legal_capabilities`; the frontend never guesses based on status. Destructive or external effects state exact scope/impact and use Plan 09 confirmation where required. Ordinary task edits commit directly with optimistic conflicts and receipts. + +### 12.7 Agent-relevant slice and notification discipline + +An agent defaults to its active attempt, parents, blocking children, material siblings, required decisions, acceptance, packet entries, workspace overlap, and handoffs. It does not see an All board or every event in its repository. + +Human notification subscriptions are explicit saved filters/channels with event classes, quiet hours, dedupe, rate budget, and authorization. Task state does not automatically subscribe the creating profile/channel. Plan-22 model-context suggestions are separately addressed and budgeted; dashboard toasts, gateway messages, hook hints, and task comments do not share an accidental notification loop. + +### 12.8 Orchestration Lab + +`/playgrounds/orchestration` is read-only and supports exact/recorded/current-best-effort replay: + +- decomposition input → normalized proposed plan diff and validation; +- readiness/gate explanation at an event/time; +- route/executor/provider/model/effort eligibility and score breakdown; +- fairness/priority queue replay; +- retry/circuit-breaker decision replay; +- context packet assembly, ranking, omissions, privacy/egress, and source anchors; +- sibling material-change → Plan-22 candidate/silence/dedupe/cooldown outcome; +- lease/heartbeat/stale/cancellation fault timeline; +- actual versus counterfactual executor/route/cost/outcome comparison; +- packet/plan/config/catalog/policy version diff; +- fixture export with secret scan and separate authorized promotion. + +Lab execution never claims, schedules, spawns, sends, updates counters, consumes budgets, changes circuit breakers, creates normal events, or mutates curation. A side-effect guard fails closed at the application layer. + +## 13. Configuration, authorization, privacy, and security + +### 13.1 Plan-20 configuration ownership + +All settings are descriptors in Plan 20 with built-in/profile/project/repository/worktree/provider/host layers only where legal. No adapter, plugin, environment helper, or dashboard file defines another default. + +Configuration families: + +| Family | Examples | +|---|---| +| Task graph | enabled, plan/decomposition limits, legal work kinds/dependencies/gates, version retention, saved-view limits | +| Scheduler | enabled/paused, concurrency hierarchy, fairness weights/floors, priority aging, batch/backpressure, heartbeat/lease/start/cancel timeouts | +| Executors | allowed adapter classes/versions/hosts, registration auth/TTL, workspace modes, capacity, drain/update policy | +| Providers/models | allowed providers/models/revisions, reasoning effort, residency, fallback policy, context/tool limits, pricing source | +| Tools/capabilities | allow/deny grant templates, effect classes, MCP/remote egress, credential refs, destructive confirmation floors | +| Workspaces/Git | allowed roots/remotes, owned versus user worktrees, branch templates, clean-state policy, retention/cleanup, delivery grants | +| Budgets/schedules | token/cost/runtime/tool/storage/network/human limits, deadlines, time windows, retry/backoff/circuit breakers | +| Context packets | token/entry limits, required classes, sibling materiality, temporal mode, expiry/refresh, model egress | +| Notifications/scout | exact event classes, quiet hours, dedupe/cooldown, per-Turn/session budgets, enabled host modes | +| Privacy/retention | sanitizer floor, sensitivity/residency, packet/log/artifact retention, redaction, quarantine, export/share limits | + +Settings UI/CLI/MCP/API/SDK show declared owner, effective source/default, revision, validation, impact, restart/drain requirement, and history. Environment values are immutable sources. Changes apply at safe boundaries: new attempts use the new generation; running attempts remain pinned or receive an explicit invalidation/cancellation decision. + +No config includes a global current board, implicit current project, first repository match, default writable worktree, or unrestricted fallback executor. Safe floors prevent disabling sanitizer, audit, fence validation, scope authorization, or secret scanning. + +### 13.2 Authorization model + +Roles/capabilities distinguish: + +- inspect own active attempt; +- inspect initiative/project/repository work; +- query All authorized work; +- create/version/assign/cancel work; +- attest/review/except acceptance; +- operate scheduler/executors; +- write workspace/Git/delivery/external systems; +- administer configuration/privacy/retention; +- run/read labs and promote sanitized fixtures. + +Every command authorizes actor, declared scope, target entity owner, project/repository/worktree relations, requested effect, and downstream implications. Cross-project initiative access is the intersection of profile authority and each selected project's policy. Partial access returns redacted/omitted relation coverage; it never leaks hidden task titles through counts, labels, errors, or graph topology beyond allowed safe rollups. + +Executor grants are narrower than the initiating human/orchestrator authority and are attempt-bound. An executor cannot query another task merely because it shares an initiative, board lens, repository, provider, host, or assignee class. + +### 13.3 Mandatory sanitizer and protected data + +Every incoming task/plan title, specification, comment, summary, decision, model proposal, tool result, log chunk, artifact, error, external issue/PR text, packet entry, saved query, annotation, and extension payload is `Unclassified`. Plan 18's structured sanitizer produces sink-specific wrappers or denies/quarantines it. + +Rules: + +- no free-form JSON metadata column or “extra” map in canonical/public schemas; +- packet, prompt, log, and artifact payloads stay in the appropriate encrypted privacy domain; +- secrets/credentials are opaque protected refs, never copied into task context; +- remote model/tool egress requires explicit sensitivity/residency grant and receipt; +- model/tool output is untrusted and cannot modify grants, gates, acceptance, scope, or instructions; +- sanitizer coverage receipts follow derived summaries, embeddings, packets, exports, hints, and artifacts; +- retroactive secret discovery invalidates descendants, packets, indexes, saved views, exports, and model eligibility; +- task graph events/audit use safe reason codes and keyed digests, not raw text; +- log viewing is separately authorized, bounded, redacted, and never injected automatically; +- fixture/export promotion runs secret scan and excludes private session content. + +### 13.4 API/adapter security + +- HTTP/plugin routes use the common auth middleware; no localhost exemption as an authorization model. +- WebSocket/SSE credentials follow Plan 10 ticket/session rules and never appear in retained logs/referrers. +- executor adapters authenticate registrations and every event/control stream; replay/sequence gaps fail closed. +- lease/grant tokens are unforgeable, attempt/epoch-bound, short lived, and never shown in normal UI/CLI/MCP. +- board/view IDs do not confer data access. +- attachment/artifact paths are server-side IDs; filenames are sanitized; size/type/decompression/path traversal limits apply. +- process environments are allowlisted; arbitrary host environment and credential inheritance is prohibited. +- command/tool arguments use typed schemas and no shell concatenation. +- audit records actor, adapter/host, scope, grant, versions, decision, effect, and outcome without secret payloads. + +## 14. Status, observability, doctor, and repair + +### 14.1 Status model + +`TaskGraphStatusViewV1` reports: + +- scheduler lifecycle lease/epoch, accepting/paused/draining state, checkpoint, queue lag, next wakeup; +- active initiatives/plans/work items by readiness/resolution, oldest age, deadline/critical-path risk; +- active leases/attempts, heartbeat age, starts/cancellations/reconciliation, stale/fenced counts; +- executor registrations by adapter/host/provider/model/effort/capability/residency and available capacity; +- packet build latency/size/omissions/staleness/privacy denials; +- retries, failure classes, circuit breakers, starvation/fairness, budget exhaustion; +- workspace preparation/drift/conflict/cleanup backlog; +- artifact/handoff/acceptance/external-effect reconciliation; +- event/outbox/projector/query/SSE lag and dead letters; +- config/catalog/policy/schema/sanitizer generations and drift; +- coverage, partial/unavailable domains, and last successful end-to-end canary. + +Metrics are low-cardinality and safe. IDs, titles, paths, prompts, branch names, raw model names where policy treats them private, and error text do not become labels. Detailed drill-down uses authorized queries and correlation IDs. + +Plan 26 is the sole accounting/observability owner. Task events and `task_cost_events` project into its generated descriptors and rollups with canonical `initiative_id`, `work_item_id`, `attempt_id`, executor registration/adapter/provider/model/reasoning-effort route, pricing/methodology version, source event, and unknown-component state available for authorized drill-down; low-cardinality public aggregates use safe dimensions/digests only. Workload and Executor Fleet views consume plan 26's task-execution runtime/cost/liveness/scheduler projections for p50/p95, rates, denominators, caps, and unknowns rather than aggregate browser rows or invent a second ledger. Every displayed number links to the underlying attempt/cost/journal evidence and declares frozen/current watermark. + +### 14.2 Doctor rules + +Doctor detects: + +- more than one task source-of-truth/scheduler/lease authority; +- plan cycles, dangling versions/memberships/dependencies, invalid gates, impossible acceptance; +- active attempt without lease, lease without attempt, duplicate active lease, nonmonotonic epoch; +- expired/unresponsive executor or manifest/config/catalog generation mismatch; +- task ready with no eligible executor/grant/model/workspace; +- scheduler starvation/fairness drift, retry storm, breaker oscillation, queue/backpressure overflow; +- stale/expired/denied packet, missing mandatory entries, bad anchor route, sanitizer floor mismatch; +- workspace identity/path mismatch, dirty ownership conflict, base/ref/snapshot drift, orphaned TraceDecay worktree; +- cancellation stuck, external effect unknown, abandoned reservations/budgets; +- artifact missing/hash/retention mismatch, handoff without outcome, acceptance terminal invariant violation; +- cross-project scope ambiguity or task/project relation without authorized provenance; +- notification/scout addressee ambiguity, repeated event spam, cooldown/budget drift; +- API/catalog/binding/output/config schema parity drift; +- legacy board/current-file/database paths still participating in live dispatch. + +Doctor is read-only by default and returns safe evidence plus cataloged repair capabilities. Repair is an explicit application workflow with preconditions, checkpoints, receipts, and backup/rollback point only where Plan 09 requires it. It never initializes an empty store over corruption or auto-kills an uncertain remote effect. + +### 14.3 Operational events and alerts + +Alert only actionable conditions: scheduler authority lost, duplicate lease invariant, terminal transaction failure, cancellation/effect unknown beyond threshold, no eligible executor for critical work, critical-path deadline breach, privacy/sanitizer failure, outbox/projector stalled, adapter protocol incompatibility, or unrecoverable workspace conflict. Normal blocked dependencies, empty queues, expected rate-limit backoff, and advisory work claims are status, not alerts. + +## 15. Required cross-repository reference workflow + +The primary implementation/evaluation fixture is one initiative spanning Rspack, Rsbuild, and `rsbuild-plugin-react-router` with exact registered project/repository/worktree/ref identities from Plan 16. + +### 15.1 Graph shape + +```mermaid +flowchart LR + Root["Initiative: cross-repo runtime change"] --> Scope["Resolve project-set and acceptance"] + Scope --> R1["Triage Rspack code and delivery evidence"] + Scope --> R2["Triage Rsbuild integration and API evidence"] + Scope --> R3["Triage React Router plugin behavior and tests"] + Scope --> H["Historical session and failure retrieval"] + R1 --> V["Verifier: reconcile claims and contradictions"] + R2 --> V + R3 --> V + H --> V + V --> S["Synthesizer: versioned implementation plan and decisions"] + S --> I1["Rspack implementation task"] + S --> I2["Rsbuild implementation task"] + S --> I3["Plugin implementation and ecosystem task"] + I1 --> X["Cross-repo integration verifier"] + I2 --> X + I3 --> X + X --> D["Delivery/PR/check/release tasks"] +``` + +Triage tasks are independently leasable and intentionally diverse. Example routing must cover separate Codex, Claude, Cursor, and Hermes/custom registrations with explicit provider/model/effort/tool grants. Verifier consumes all required handoffs, flags scope/source disagreements, and cannot pass on simple majority. Synthesizer creates decisions, acceptance criteria, and implementation dependencies. Implementation tasks bind distinct worktrees/branches and cannot mutate sibling repos without grants. Integration verifier runs exact affected/ecosystem tests at pinned commits. Delivery work is separately authorized. + +The fixture must also exercise a realistic manual partition: one bounded transactional `work_items.assign_set` pins a handful of Rspack/plugin work items to eligible Codex routes and a different handful of Rsbuild/integration items to eligible Claude routes, leaves two discovery tasks policy-routable, and later rebalances one unstarted item. Assignment is a versioned route constraint, not board membership; provider queue views are projections over requested/actual route receipts. The set command is all-or-none under the owner plan/version and returns deterministic per-item receipts. Rebalancing cannot steal a live lease, change an attempt's start manifest, expose sibling prompts, or erase the original decision. An agent active in two initiatives receives two distinct attempt packets and task-aware slices, never the union of both boards. + +### 15.2 Context and notification expectations + +Each triage packet includes only its repository scope plus initiative objective, shared acceptance, relevant historical anchors, and read-only sibling-repository interface evidence. It does not dump all sessions or sibling prompts. Verifier packet includes triage handoffs/contradictions. Implementation packets include accepted synthesis decisions, exact parent artifacts, relevant sibling interfaces, tests, worktree/base bindings, and residual risk. + +If the Rspack task changes an interface used by Rsbuild, projector emits a material event. Plan 22 may deliver one exact advisory to the active Rsbuild implementation Turn with safe summary + anchors. Unchanged heartbeat/progress, unrelated file edits, or planned parallel benchmarking produces no hint. Dashboard updates the shared projection without messaging every agent. + +Context packets and hints distinguish shared initiative context from provider partitioning. Every worker gets the common objective, acceptance contract, dependency decisions, and exact cross-repository interface anchors needed for its work, plus only material sibling deltas since its packet watermark. It never receives “Claude is on board X” as ambient prose: it receives a typed related-work summary naming canonical work-item/attempt IDs, safe status, relation/materiality reason, affected interface/resource, and retrieval anchors. The same record powers the dashboard overlap lens, `find-nearby-work`, packet refresh, and useful-silence replay so coordination cannot fork into four inconsistent awareness systems. + +### 15.3 Required assertions + +- one initiative/plan graph, no task copies per repository; +- same-name files/symbols remain repository/snapshot-distinct; +- all work items retain project/repository/worktree relations and owner profile; +- search/load/context follow stable anchors across registered project shards; +- planned diverse triage is not flagged duplicate; +- accidental duplicate research with direct overlap is detected once; +- matching `query_scope`/query digest plus scope/goal/anchor evidence detects duplicate research once, while declared ensemble/shared-work children suppress it; +- shared execution materializes independently leased child work under one aggregate parent; two authoritative executors never lease the same work item; +- verifier does not unlock before all required gates or authorized exception; +- packet versions reflect parent/sibling decisions without leaking unrelated content; +- executor routes record requested/actual model/provider/effort/grants; +- every attempt cites an accepted manual or offer-pinned policy assignment; policy-routable unassigned work first receives a proposed assignment in its offer and activates that exact assignment atomically with lease issuance on accept; +- push and pull observe one canonical offer; accept yields at most one attempt, while decline/revoke/expiry yield none; +- packet refresh preserves the immutable start packet and advances only the fenced accepted-packet ordinal at the declared Turn boundary; +- attempt list/detail/timeline, offer, packet, and notification operations have generated CLI/MCP/HTTP/Rust/TypeScript/Python parity; +- no ambient CWD/current board/base checkout substitution; +- dirty/conflicted worktree blocks safely; +- stale worker cannot complete after fence epoch changes; +- cancellation/retry does not duplicate Git/PR effects; +- All, repository, agent, board, DAG, critical-path, and timeline lenses show the same canonical selection/counts. + +## 16. Migration, compatibility, and convergence + +### 16.1 Inventory and classification + +Before migration, inventory: + +- current TraceDecay goals, tasks, workflows, work claims, agent presence, automation jobs/runs/artifacts, scheduler decisions, and coordination events; +- provider-native Codex goals/plans, Claude workflows, Cursor/Hermes agent runs, subagent/delegation relations, and provider task-like metadata; +- Git branches/worktrees/commits/PRs/checks/releases associated with work; +- external issue/task systems and optional Hermes Kanban stores configured as capture sources (after merged PR #407, these arrive through the ordinary user-profile capture source; refresh the recorded source/merge manifest before import); +- dashboard/private plugin task state, CLI/MCP commands, config keys, logs, and notification subscriptions. + +Classify each source as canonical candidate, external observed entity, alias, projection, artifact, or obsolete duplicate. Observation does not automatically materialize schedulable work. + +### 16.2 Import rules + +- profile activity is the only destination owner for canonical task graph mutations; +- preserve external/native IDs as aliases with source/commit/schema provenance; +- import immutable history before derived current state; +- infer no hidden assignment, scope, completion, dependency, or causal relation without evidence; +- cyclic/ambiguous graphs remain legacy-quarantined with repair diagnostics; +- provider-native goals/workflows remain native entities linked to tasks; materialization requires an authorized idempotent command; +- automation jobs remain automation entities; they may create/link work through application commands but are not duplicated task schedulers; +- Hermes Kanban import, if enabled, treats each board DB as a versioned external source, ignores ambient `current`, maps task/run/link/event/attachment evidence, and never runs Hermes dispatch against canonical tasks; +- do not import raw secrets/logs/attachments before Plan 18 scanning/classification; +- duplicate rows/boards/store backups are clustered as observations, not separate canonical work items, until identity evidence resolves them. + +The importer reads each source in one frozen manifest order: `tasks`, `task_links`, `task_runs`, `task_events`, `task_comments`, `task_attachments`, notification subscriptions, then dispatcher metadata. Every source record receives exactly one plan-12 disposition—`retained`, `skipped`, `quarantined`, `redacted`, or `deleted`—with reason, source key, sanitizer receipt, target refs, and import watermark; no row disappears behind a count. `deleted` is legal only when the source itself contains a witnessed deletion/tombstone, never as an import cleanup choice. + +Hermes `blocked` is polysemous. Import replays each task's ordered `task_events` and associated run IDs to classify the last effective transition as `StickyWorkerOrOperatorBlock`, `CircuitBreakerGaveUp`, `DependencyBlock`, or `AmbiguousLegacyBlock`. A status column without a consistent event path produces `AmbiguousLegacyBlock` and quarantine/diagnostic evidence; it never fabricates readiness or a retry counter. Historical run rows become immutable `ImportedExecutionObservationV1` records under the existing provider-native workflow/run evidence family: source manifest/native run ID, linked imported work item, observed ordinal/status/times, requested-route evidence, workspace locators, artifacts, sanitizer receipt, and missing-field reasons. They are not `ExecutionAttemptV1`, have no assignment/executor/workspace/packet/grant/fence authority, and cannot enter attempt queries except through an explicitly labeled imported-observation lane. In-flight claim/PID/current-run fields are skipped and can never become a live lease. Attachments are content-read through plan 18 scanning into protected/artifact blobs; missing absolute paths remain unavailable locators. Comments become sanitized comment artifacts, except structured swarm blackboards, which are schema-validated into versioned imported packet/decision evidence or quarantined when invalid. + +The audited Hermes `kanban_db` schema (§2.1) maps field-by-field; no field is imported without a listed rule: + +| Hermes `kanban_db` evidence | V2 target | Import rule | +|---|---|---| +| task/board IDs | aliases on imported `WorkItemId` | canonical UUIDs are freshly allocated; uniqueness is `(source_manifest_id, board_slug, native_task_id)` and the safe `hermes::t_` form is an alias/display locator only; source DB path/commit/schema version recorded as provenance | +| title/description/comments | `WorkItemVersionV1.title`/`specification` plus comment artifacts | plan 18 sanitizer first; imported as one initial version | +| status strings (including `scheduled` without `scheduled_at`) | `WorkItemDispositionV1` + `WorkResolutionV1` | replay ordered `task_events` before mapping `blocked`; no fabricated timestamps or readiness; inconsistent/missing event history becomes `AmbiguousLegacyBlock` quarantine with a `DiagnosticEnvelopeV1` | +| dependency links and promotion records | `TaskDependencyV1` gating edges when acyclic; non-gating relations otherwise | cyclic/ambiguous graphs stay legacy-quarantined | +| `runs` rows (attempt-like history, retry counters, runtime/heartbeat fields) | one nonauthoritative `ImportedExecutionObservationV1` per native run; counters become observed ordinals | missing provider/model/effort/assignment/workspace/packet/grant fields remain explicit `Unavailable(reason)`; no `ExecutionAttemptV1`, fence epoch, lease, or `ActualExecutorRouteV1` is invented | +| worktree/branch strings | `WorkspaceBindingV1` locator evidence only | strings are locators, not identity; no live rebinding | +| per-task model override/skills | requested-route evidence on the imported execution observation | grants/authority are never derived from imported preferences | +| claims/dispatch/recovery rows | advisory `WorkClaimV1` evidence and lease-history observations | never imported as live `TaskLeaseV1`; no fence epochs minted from V1 data | +| attachments/logs | plan 18-scanned `TaskArtifactV1` and protected log streams | quarantine before any ordinary store | +| notifications | summarized observation events | no notification subscriptions or loops imported | + +V1 TraceDecay goals, work claims, and provider task-like entities materialize into canonical work items only when all three hold: an authorized idempotent materialization command runs; the source shows live owner intent (an open goal/claim with recent activity, or explicit user selection); and scope resolves through plan 16 without ambiguity. Everything else remains observed evidence linked by alias. + +### 16.3 Shadow and cutover + +1. Land schemas/domain/repositories with no live scheduler. +2.

The indexer library consumes only those sanitized observations: it parses receipt-bound file content with registered versioned grammars, derives symbol occurrences, code edges, diagnostics, and test attributions, and plans deterministic packed-generation builds. V1 migration follows the same boundary: plan 02's store-owned read-only importer and the root migration adapter discover/open legacy SQLite families and emit receipt-bound logical graph-import batches; this crate never opens a V1 database. Plan 04's `code_evidence_v1` projector executes each build transactionally through a projector-owned port over plan 02's `GraphGenerationRepository`; plan 05 queries the published generations.

This crate never stages/seals a store handle, opens a database, or calls `publish_generation`; publication/atomic swap remain plan 02's sequence executed under plan 04's projector transaction. +- The plan-02/root V1 adapter is the only constructor of `V1GraphSourceManifestV1`/`V1GraphImportBatchV1`. It discovers tracked and metadata-less graph files, opens each SQLite family read-only through the store connection factory with effective `PRAGMA mmap_size=0` read back and enforced, runs integrity/schema checks, sanitizes through plan 03, and emits bounded logical rows. This crate can compare/lower those rows but has no raw path, SQLite handle, database bytes, or raw digest. +- Import replay keys are `(source_manifest_id, ordinal)`. `source_file_fingerprint` is private evidence with explicit privacy domain and key epoch, not a canonical ID or public equality token. Historical manifests remain immutable across key rotation; plan 02 records a signed successor/continuity receipt between old-epoch and new-epoch source manifests instead of changing an existing row or computing an unkeyed digest. +- Ordering: plan 04 PR 18 first lands the projector-owned consumer contract, transaction, and fake builder without a production dependency. PR 18B–18F then land and prove this crate. Plan 04 PR 18G, after plan 02 PR 6C and PRs 18B–18F, adapts the real `CodeIndexBuilderV1` into that already-tested projector transaction. Projector framework tests retain the fake builder so the stack remains bisectable. + +### Consumed observation families and derived-row lineage + +The `code_snapshot` adapter (plan 03) commits these sanitized observation payload kinds; they are the crate's only content inputs and the payload families plan 04's registry must show owned by `code_evidence_v1`: + +- `code.snapshot_observed` — repository/checkout/worktree/ref tuple, snapshot kind (commit or dirty overlay base), source watermark. +- `code.file_observed` — file path, language hint, `PrivacyDomainKeyedFingerprintV1` (privacy domain + key epoch + keyed digest), receipt-bound sanitized content reference, redaction-marker spans. +- `code.file_removed` — deletion evidence for incremental planning. +- `code.diagnostic_observed` / `code.build_observed` / `code.test_run_observed` — tool outputs framed by capture from compiler/LSP/test processes. + +Every row this crate derives (occurrence, edge, diagnostic mapping, test attribution, FTS/fingerprint auxiliary) records the observation IDs and receipt IDs it descends from. Receipt revocation or a retroactive privacy finding (plan 18 §12) invalidates descendants through plan 04 PR 10A's lineage mechanism and forces `PrivacyPolicyInvalidation` rebuilds scoped to the affected files — never a whole-profile rebuild by default. + +### Deterministic identity, canonical rows, and generation digests + +- A symbol entity's seed identity is `(repository, language, qualified_path, kind, disambiguator)`; the disambiguator covers overload arity/signature and same-name siblings. Seeds propose; the store's identity ledger allocates (plan 01's `AllocationRequest` path for entities lacking an exact native key). A seed collision with a live different-lineage entity is surfaced as an `identity_collision` conflict, never silently reused — the regression class behind PR #269/#371 in plan 14 §2 (its `FM-###` row IDs bind PR 33G/18F receipts). +- Occurrence identity is `(snapshot, file, byte range, kind)` — deterministic, snapshot-scoped, and independent of allocation order. +- Canonical row ordering is total and fixed: files by path bytes, occurrences by `(file, byte_start, kind, qualified_path)`, edges by `(source_occurrence, kind, target)`, diagnostics by `(file, byte_start, tool, code)`, test-map rows by `(test, covered_entity)`. The generation digest is computed over the canonical uncompressed ordered rows plus `BuildInputDigests`; compression, page layout, and physical file boundaries are excluded. +- Same sanitized source rows + same `BuildInputDigests` ⇒ same `GenerationDigest`, on any machine, in any parallelism configuration. Two consecutive builds asserting digest equality is a release gate. +- Content fingerprints stored in generation tables are the full privacy-domain-keyed identity tuple carried from capture — privacy domain, key epoch, and keyed digest — never a bare digest.

The keyed fingerprint's privacy domain, key epoch, and keyed digest all survive physical lowering; it is private integrity evidence, not an idempotency key or public token.

Numerators and additive values use checked integer addition. Ratios/percentiles are recomputed from retained counts or bounded sample references; they are never averaged. A configuration boundary produces separate points instead of laundering two definitions into one value. +- Denominator merge is total: all-`Known` children sum to `Known`; `Known`/`Capped` children with complete coverage sum observed and effective caps into `Capped`; any mix containing `Partial` or an `Unknown` child plus observed children becomes `Partial` with the merged source watermark and sorted/deduplicated reasons; a window with no observed population remains `Unknown`. Overflow, non-adjacent windows, dimension mismatch, or incompatible descriptor versions fails the projection instead of emitting a point. +- Renderers (CLI tables, MCP markdown, dashboard panels, API JSON) receive `MetricPointV1` and must render the state.

"Fresh-looking stale data" is a named regression, not a cosmetic issue. +- Population definitions are part of the descriptor, so two surfaces can never disagree about what "sessions with hints" counts — the plan 21 parity gates hold because the number is computed once. + +Legal renderings per state, enforced across every surface by the shared conformance fixtures: + +| `DenominatorState` | Legal rendering | Forbidden rendering | +|---|---|---| +| `Known(n)` | Exact value/ratio with `n` visible on demand | Hiding `n` when the descriptor requires it | +| `Capped{observed, cap}` | Value "of first `cap` sampled" with drill-down to the cap event | Whole-population percentage; omitting the cap | +| `Partial{watermark}` | Value "as of `watermark`" with missing-component list from coverage | Presenting as complete; averaging over missing windows | +| `Unknown{reason}` | The unknown state with its reason | `0`, `0%`, `—` styled as a value, or an empty chart segment | + +### Ingest/projection lag and data quality + +- Lag series sample capture source watermarks against journal commit time (`IngestLagSampled`) and journal outbox positions against projector checkpoints (plan 04's contiguous/highest sequences) per `(shard, projector)`; the cutover gate "projection lag < 2 s for 24 h" (master §7.7) reads from these rows, not from an ad-hoc probe. +- Data-quality series count dead letters by reason, quarantine entries, unknown-denominator metric points, coverage omissions, and parse/schema failures — the inputs the Observatory needs to say *why* a number is partial. + +### Cap/truncation telemetry with retrieval anchors + +- Any surface that applies a cap (query page/budget, hint token budget, export bound, traversal depth, analytics sample) emits `CapApplied` with a `CapTruncationRecordV1`. Where the truncated population is retained evidence, the record carries a `RetrievalAnchorId` routing to the exact frozen result (anchors are ID-only in rows; hydration goes through the anchor endpoint per plan 01's rule). +- Cap membership is normalized: `MetricPointV1.cap_events` lowers only to `metric_rollup_cap_events`, and `cap_event_count` is computed as `COUNT(*)` over rows matching the rollup's full seven-column parent key. No counter column exists on `metric_rollups` to drift from membership. Hydration orders by `ordinal`, joins `cap_truncation_events`, and verifies the computed count equals the emitted vector length, so "this 30-day adoption panel is computed over a 10k-event sample cap" remains one click from the exact evidence. +- Merged PR #424 is accepted-base behavior: exact event totals and tool/hint aggregates execute in storage over the entire declared scope/window before any presentation sample; raw event lists remain cursor-paged and capped separately. The >10,000-event regression joins plan 14 `FM-086`. V2 generalizes the correction through registered metric descriptors and shared read models rather than preserving three bespoke SQL helpers. + +### Per-capability adoption analytics + +- Adoption rows key on `(capability_id, surface, provider, scope_digest, window)` with invocation counts, distinct sessions, and an eligible-population denominator (sessions where the capability was installed/available — from plan 08's catalog availability states). The V1 evidence (59,618 hook calls vs 522 sampled MCP tool calls; hook-to-tool adoption "weak and must be measurable by category and session", master §2.1) becomes a standing, segmentable series. +- Tool/fact/skill/automation/query adoption required by master §21 all use the same descriptor + rollup machinery; no bespoke counter paths. + +### Hint outcome rollups + +- Source of truth is plan 06 §10's `HintOutcomeRecordV1` (defined there, stored per plan 02's hint outcome tables, projected terminal by plan 04's `policy_hint_v1`). This plan owns only the rollup: counts of eligible/emitted/delivered/observed/acted/ignored/corrected/missed/unresolvable plus every closed `OutcomeTerminalV2` variant per policy version, hint category, horizon bucket, and scope, each with explicit denominators and unresolved-horizon visibility. +- No adoption "rate" renders without denominator and horizon (plan 14 §4's hint-outcome row); `unresolvable` is a visible bucket, never dropped from the population. +- The V1 join impossibility (1,182 emitted / three acted, weakly joined across analytics and hook JSONL) is closed by plan 12's migration mapping V1 analytics/hook JSONL into V2 outcome records; PR 33H proves the historical join renders with correct unknown-states for rows whose outcomes are genuinely unattributable. +- `missed_capability{capability_id}` is an opportunity denominator, not an emitted/delivered/ignored hint. `PreventedDuplicateWork` requires plan-06 linked claim/handoff/scope evidence and is separate from generic `Acted`. `HumanHelpful`, `HumanNotHelpful`, `HumanIncorrect`, `HumanTooLate`, `HumanRepeated`, and `HumanTooVerbose` each retain their own count and feedback-evidence drill-down; no `Human*` value is collapsed into corrected/negative. One record may contribute to its lifecycle stage plus exactly one terminal-variant bucket, never two terminal buckets. + +### Task/executor liveness and scheduler rollups + +Plan 24 owns liveness decisions and plan 02 owns attempt/lease/liveness/sentinel rows.

It always reports the definition/version/window/evidence; temporal proximity alone cannot blame the scheduler. Cardinality dimensions are bounded to adapter/provider/model/decision class and opaque scope digest—never task title, path, prompt, or raw error. + +The projector consumes the closed plan-24 `TaskLivenessEventClassV1` registry through a generated exhaustive match: every variant maps to exactly one primary liveness column and may additionally contribute to explicitly declared orthogonal episode/latency columns. There is no wildcard/default arm. Schema-generation tests fail when plan 24 adds or renames a lease, probe, revocation, replacement, requeue, crash, cancellation, reconciliation, effect-unknown, or terminal class without a column and fixture; unknown imported V1 classes increment a visible `imported_unknown` column and never masquerade as zero. + +### SLO monitors + +Registered SLO descriptors at minimum (thresholds are plan 20 descriptors defaulting to master §26/§5.3 values): + +| SLO | Target | +|---|---| +| Notification-only hook total | p95 ≤ 10 ms | +| Prompt-evaluation hook total / evaluation stage | p95 ≤ 25 ms / ≤ 14 ms | +| Scout pending-envelope claim (hook wait) | p95 ≤ 2 ms | +| Ingest append (excl. blob I/O) | p95 ≤ 20 ms | +| Projected event visibility | p95 ≤ 2 s | +| Scoped FTS | p95 ≤ 150 ms current scale | +| Current-registry top-k | p95 ≤ 800 ms | +| Timeline first page | p95 ≤ 200 ms current scale | +| Task lease / heartbeat (plan 24 surfaces) | p95 ≤ 50 ms / ≤ 20 ms | + +Monitors compute windowed p50/p95/p99 from latency events, record breaches with reasons and sample counts, and never sample away breaches: a capped sample renders `Capped`.

Surface/provider/model IDs are generated/canonical; projection validates them against the bound catalog generation and quarantines unknown codes instead of storing labels. UNIQUE `(source_event_id)` (idempotent projection). Indexes `(occurred_day)`, `(capability_id, occurred_day)`, `(surface_code, occurred_day)`, `(provider_id, model_entry_id, occurred_day)`.

This protected high-cardinality child is the authorized drill-down/join projection for Workload, Executor Fleet, task/attempt/cost, and source-event views. Canonical IDs never enter metric labels or `metric_dimension_sets`; deleting/retiring task evidence follows plan-18 lineage and removes or tombstones this join consistently with the source ledger. | +| `metric_dimension_sets` | `dimension_digest BLOB(32) PK`, nullable typed columns `provider_id`, `model_ref_blob_id`, `use_case_id`, `surface_code`, `projector_id`, `executor_adapter_code`, `work_item_kind_code`, `failure_class_code`, `sensitivity_code`, plus `canonical_blob_id BLOB NOT NULL`, `registry_digest BLOB(32) NOT NULL`, `catalog_generation INTEGER NOT NULL`, `catalog_digest BLOB(32) NOT NULL`.

Value CHECKs make the row a lossless lowering of `MetricValue`; fixed windows are half-open/aligned, and descriptor unit/dimension masks are checked on projection. A rollup cannot combine children with different effective-config digests; a config boundary creates separate points instead of colliding in the PK.

Retained 1 year. | +| `adoption_rollups` | PK `(capability_id, dimension_digest, scope_digest, window_start)` with FK `dimension_digest -> metric_dimension_sets`; the dimension set carries generated `surface_code` and canonical provider/model IDs. `invocations INTEGER NOT NULL`, `distinct_sessions INTEGER NOT NULL`, `eligible_population_denominator_id BLOB NOT NULL REFERENCES denominator_states`, `watermark BLOB NOT NULL`.

The safe, content-free event skeleton is retained until `max(occurred_at + 180 days, latest retention horizon of every referencing rollup)`; with default day rollups that means at least 2 years. Anchor payload availability follows its own retention and may resolve to a tombstone, but the anchor ID/event skeleton stays auditable. FK-restricted cleanup cannot delete a referenced skeleton.

Parent deletion cascades membership only after the parent horizon; event cleanup then evaluates remaining references. It losslessly lowers `MetricPointV1.cap_events`; `cap_event_count` is the normalized `COUNT(*)` for the full parent key, never a stored counter.

the drift gate proves no surface renders an unregistered number. +- The misreporting matrix passes on every surface: no unknown-as-zero, no capped-as-whole, no empty-section-with-skipped-shards, no fresh-looking stale data, no rate without denominator and horizon. +- Historical fixtures reproduce the V1 evidence correctly: the migrated corpus renders the 388k-row population where V1 printed zero, and the hint/adoption series carry explicit unknown buckets. + +### Performance + +- Ledger append and rollup projection stay within plan 04's projection budgets (visibility p95 ≤ 2 s under concurrent capture); accounting adds no synchronous work to the hook path (hooks emit events; the hook budgets are monitored, not consumed, by this plan). +- Observatory/Costs first page p95 ≤ 200 ms at current scale from rollup rows, without scanning ledgers; drill-down queries are cursor-bounded. +- SLO monitor sampling overhead is measured and bounded; monitors run in background lanes, never in hook or query hot paths. + +### Privacy + +- Every telemetry table passes the secret-corpus canary: safe IDs, kinds, counts, keyed fingerprints, and watermarks only; no query literals, prompts, payloads, or path+content joins (master §21's logging rule enforced by type). +- Privacy-event rollups (redactions, locked content, denied exports) count without describing; drill-down requires the authorized source query, not the metric row. +- Scope digests in rollup keys are privacy-domain-bound; cross-domain equality probes via metric keys are impossible. + +### Observability of the pipeline itself + +- Lag, dead-letter, and data-quality series cover the accounting projectors too; a stalled accounting projector is visible in the Observatory it feeds within one sampling window. +- Every panel names its watermark, coverage, caps, and descriptor versions; every SLO record names its threshold source. + +## Verification + +Run after the last slice of each phase touchpoint, on copied real stores plus the redacted fixture corpus: + +1. `cargo test -p tracedecay-domain accounting` — contract, registry, compile-fail, and rendering-law tests pass; registry digest stable across two generations. +2. `cargo test -p tracedecay-projectors --test accounting_semantics --test slo_adoption_suite` — idempotent ledgers, deterministic rollups, SLO windows, denominator propagation, exact cap-event joins, and parent-horizon skeleton retention. +3. `cargo test --test analytics_migration_parity` — dispositions complete, historical fixtures correct, zero `unexplained`. +4. Cross-surface parity: render the five panel fixtures through plan 21's conformance harness for CLI, MCP (Markdown and canonical JSON), HTTP, and dashboard snapshot; semantic values identical, states preserved. +5. Misreporting lint sweep over every rendering call site: zero unknown-as-zero, capped-as-whole, or coverage-suppressing paths. +6. Secret-corpus canary over `usage_ledger`, all rollup tables including `metric_rollup_cap_events`, `cap_truncation_events`, `lag_snapshots`, SLO records, logs, and exported panel payloads: zero content-bearing bytes. +7. Rebuild drill: drop all rollup/telemetry tables, rebuild from canonical events at a frozen watermark, and diff against the pre-drop manifest — identical. +8. Lag-gate rehearsal: drive the 24-hour projection-lag window from `lag_snapshots` on the shadow profile and confirm the cutover gate consumes these rows and nothing else. +9. Observatory self-visibility: stall the accounting projector in a test profile and confirm the stall is visible in the Observatory within one sampling window. + +## Definition of done + +- The Observability/Accounting bounded context has one owner: descriptor registry, event contracts, ledgers, rollups, SLO monitors, adoption/hint-outcome/data-quality/lag series, and Observatory/Costs contracts are specified here and implemented in their owning crates with no V1 counting path left after retirement. +- Every metric on every surface declares population, horizon, cap, watermark, and unknown state; the no-misleading-zeros law is enforced by types, lints, and cross-surface fixtures. +- Cap/truncation telemetry with ID-only retrieval anchors makes every bounded answer recoverable and every sampled statistic honest. +- Per-capability adoption and hint-outcome rollups are standing series with denominators; the 59,618/522 and 1,182/3 asymmetries are reproducible queries, and the historical join renders with correct unknowns. +- SLO monitors continuously track the master §26/§5.3 budgets with breach records; the 24-hour lag cutover gate reads from this plan's series. +- Plan 11 renders sealed models only; plan 20 owns every tunable; plan 12 migration landed with dispositions and FM-bound receipts; plan 14 §6 regression tests pass; plan 19's ownership matrix shows the V1 analytics stack retired. +- All release gates above pass on copied real stores, and the divergence receipts for corrected V1 defects are published with the cutover.
