Subject: [PATCH 001/113] Self-heal NyxID binding rejections + streaming-failed
 reply token loop
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two production failure modes observed 2026-05-03 leave a Lark user
visibly stuck even though the cluster is healthy. Both healed locally,
no NyxID changes:

(1) /llm /route /model says "binding 已失效, 请发送 /init" while /init
says "已绑定, 请先 /unbind". After PR #558 re-DCR'd the cluster's
OAuth client to add the `proxy` scope, the user's existing NyxID
binding (issued for the previous client_id) is rejected at broker
token-exchange. ModelChannelSlashCommandHandler caught the rejection
and pointed the user at /init — which then refused because the local
readmodel still holds the (now-dead) binding_id, looping the user
forever.

Self-heal: when the broker throws BindingRevokedException /
BindingNotFoundException / BindingScopeMismatchException, dispatch
RevokeBindingCommand to the local ExternalIdentityBindingGAgent
(reason="auto_self_heal_*") so the readmodel flips to revoked, and
tell the user the binding was cleared and /init will work now.
Mirrors the dispatch shape UnbindChannelSlashCommandHandler uses
for explicit /unbind, but skips the NyxID-side revoke (NyxID is the
one that just told us the binding is gone).

(2) Bot replies as "..." forever when the LLM call fails. The
streaming sink fires the first chunk via channel-relay/reply,
consuming the single-use reply token and creating a placeholder
message. If the LLM then fails (e.g. upstream 429), pre-fix the
runtime fell through to RunLlmReplyAsync which issued a fresh /reply
against the dead token and got `401 Reply token already used` —
leaving the user staring at "..." with no error explanation.

Self-heal: ConversationGAgent.TryCompleteStreamedReplyAsync now
takes the Failed branch when streaming has already committed the
placeholder. Edits the existing message in place via
RunStreamChunkAsync (channel-relay/reply/update — no reply token
needed) with the classified failure text, then persists
ConversationTurnCompletedEvent so the runtime envelope retry loop
does not refire and consume the dead token again. If the edit also
fails (rare: Lark may refuse stale-message edits), persist the
last flushed partial as terminal — same defence-in-depth pattern
the existing PR #374 fix uses for the Completed path.

Tests:
  - 4 new ModelSlashCommandHandlerTests pinning the binding self-heal
    for each rejection shape + degraded-path when IActorRuntime is
    missing.
  - 2 new ConversationGAgentDedupTests pinning the streaming-Failed
    branch edits the placeholder + falls through to "persist last
    flushed partial" when the edit also fails.

Verification:
  dotnet test test/Aevatar.GAgents.ChannelRuntime.Tests --no-build (851/851)
  dotnet test test/Aevatar.GAgents.Channel.Protocol.Tests --no-build (36/36 in dedup suite)
  dotnet test test/Aevatar.Foundation.Core.Tests             (230/230)
  bash tools/ci/test_stability_guards.sh                     (passed)
  bash tools/ci/query_projection_priming_guard.sh            (passed)

From: eanzhao <yiqi.zhao@aelf.io>
Date: Mon, 4 May 2026 11:20:59 +0800
Subject: [PATCH 002/113] Address PR #561 review (codex P2 + eanzhao): honest
 self-heal failure path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Both reviewers caught the same bug: pre-fix the self-heal returned the
"本地已自动清理" message even when IActorRuntime was unregistered or
when CreateAsync / HandleEventAsync threw — the local readmodel was
NOT actually cleaned in those paths, so the user follows the message
to /init, /init still sees the stale binding and refuses, recreating
the exact loop this PR exists to break.

Split the self-heal API into cleanedMessage + degradedMessage. The
cleaned message is returned ONLY when the local revoke envelope was
actually dispatched to the binding actor; otherwise the degraded
message points the user at /unbind explicitly.

Also add a single retry on the dispatch path (mirror
UnbindChannelSlashCommandHandler's PR #521 v4-pro review fix) so a
one-off Orleans hiccup doesn't downgrade an otherwise self-healable
binding to manual /unbind guidance.

Tests:
  - List_DegradesToUnbindGuidance_WhenSelfHealActorRuntimeMissing now
    asserts the reply contains "/unbind" and DOES NOT contain
    "已自动清理" — pinning the no-runtime degraded path.
  - List_DegradesToUnbindGuidance_WhenSelfHealDispatchKeepsThrowing
    is a new test exercising ThrowingActorRuntime (every CreateAsync
    throws) and asserts AttemptCount == 2 (retry-once contract) plus
    the degraded reply shape.

Verification:
  dotnet test test/Aevatar.GAgents.ChannelRuntime.Tests --no-build (852/852)
  bash tools/ci/test_stability_guards.sh                     (passed)

Subject: [PATCH 003/113] Propagate reasoning_content through LLM pipeline
 (fixes #563)

DeepSeek v4-pro with thinking mode rejects requests when reasoning_content
from prior assistant turns is not echoed back. This change:

- Adds ReasoningContent to ChatMessage, LLMResponse, and LLMStreamChunk
- Propagates reasoning content through ChatRuntime streaming rounds
- Appends reasoning_content to conversation history for multi-turn
- Implements ExtractReasoningContent in MEAILLMProvider
- Wires reasoning content into non-streaming ConvertResponse

Closes #563

Subject: [PATCH 004/113] Gracefully handle missing scope in UserMemoryStore
 (fixes #564)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Channel conversation LLM runs inside Orleans actors with no HTTP auth
context. The scope resolver returns null, causing
ActorBackedUserMemoryStore to throw InvalidOperationException on every
turn and log a warning.

- Add TryResolveScopeId/TryResolveWriteActorId that return null instead
  of throwing
- ReadProjectedStateAsync returns null when no scope is available
- GetAsync returns UserMemoryDocument.Empty, BuildPromptSectionAsync
  returns empty string — no warning logged
- Write operations (Save/Add/Remove) still throw since they only run
  from Studio API with auth context

Closes #564

Subject: [PATCH 015/113] fix(skill-runner): treat zero-tool-call runs as
 failure for fetch-and-summarize skills (#439)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PR #471 closed the all-fail path of issue #439's fake-success bug: when every
nyxid_proxy call in a daily_report run returns 4xx/5xx, EnsureToolStatusAllowsCompletion
throws and the runner records SkillRunnerExecutionFailedEvent. The remaining gap
flagged in PR #471 review (SkillRunnerGAgent.cs:407, SkillRunnerToolFailureSafetyNetTests
Policy_NoToolCallsAtAll_Allows): if the LLM bypassed tools entirely and produced output
from prior context, both counters stay at zero and the safety net passes the run as
clean success. That's the original #439 symptom — 52 commits in 24h reported as "No
meaningful public GitHub activity" with no tool errors to count.

This adds a per-skill RequiresNyxidProxySuccess flag carried on the SkillRunner
state/init event (proto field 21/16/16). When the flag is set, a run that completes
with zero successful nyxid_proxy calls now throws — routing through the same
HandleTriggerAsync catch path as the all-fail mode, so /agent-status surfaces a
non-zero error_count and a meaningful last_error instead of a fake success.
daily_report's template spec opts in; skills that don't depend on tool data
(future pure-LLM transformations) leave the flag false and pass through.

When the all-fail and never-called branches would both fire, the all-fail message
wins because it names the count of failed tool calls, which is more actionable for
the operator.

Subject: [PATCH 016/113] Add operator rebuild endpoint to unwedge OAuth client
 at NyxID
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Production wedge (issue #549) post K8s rolling deploys leaves
AevatarOAuthClientGAgent pinned to a stale client_id with broken
redirect_uri. Existing OCC absorber (commit 9326204d) prevents the
loop but cannot replace the wedged snapshot itself — the cluster
needs an explicit ops handoff that points aevatar at a freshly-
created NyxID client without DB access.

Adds:
- Extends ProvisionAevatarOAuthClientCommand with redirect_uri so
  manual provisioning persists the full snapshot the next bootstrap
  pass needs to skip drift detection.
- HandleProvision now writes redirect_uri to the persisted event and
  treats (client_id, authority, redirect_uri, oauth_scope) as the
  same-snapshot key — pre-fix it ignored redirect_uri/oauth_scope so
  partial heals silently no-op'd.
- AevatarOAuthAdminOptions binds ChannelIdentity:Admin:RebuildToken;
  empty token leaves the rebuild endpoint fail-secure (503).
- POST /api/oauth/aevatar-client/rebuild: body { client_id,
  redirect_uri?, oauth_scope?, client_id_issued_at_unix? }, header
  X-Aevatar-Admin-Token, constant-time compared. Activates the
  projection scope, dispatches ProvisionAevatarOAuthClientCommand,
  waits up to 30s for the readmodel to reflect the pin, returns
  200 on success / 202 pending on timeout / 401 / 400 / 503 on auth +
  validation failures.

Other layers from issue #549 (distributed-lock bootstrap, sync grain
RPC dispatch, ProjectionScopeGAgentBase OCC absorber, multi-silo CI
test) are intentionally out of scope and tracked as follow-ups.

Subject: [PATCH 018/113] Wrap up issue #513 follow-ups: /whoami no-auth,
 override matrix, callback hint
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three small loose ends from the per-user NyxID binding tracking issue:

- Phase 6: /whoami previously had RequiresBinding=true so unbound senders
  hit the binding-gate prompt instead of seeing their own state. Issue #513
  explicitly carves /init, /unbind, and /whoami out of the auth requirement
  so an unbound user can introspect "am I bound?" without bouncing through
  /init. Switch RequiresBinding=false and branch on bindingId in the handler
  itself: bound senders still get the masked binding info; unbound senders
  see "未绑定" with a /init hint.

- Phase 3: existing tests cover sender-overrides-model, sender-store-throws,
  and route-failure-retry, but not the explicit 3 binding × 3 owner-prefs
  matrix the issue asked for. Add a [Theory] with all 9 cells (unbound /
  bound-empty / bound-model-only) × (owner-none / partial / full). Sender
  prefs in the bound-set row deliberately set only DefaultModel so we
  exercise "sender supplies a subset, owner fills the rest" without crossing
  the route-applied + no-sender-token branch already covered elsewhere.

- Phase 1: callback success response is now an HTML page that names the
  /model and /whoami next-step commands. Full version is a Lark card update
  pushed back into the chat, which requires capturing the /init card's
  message-id and threading it through the OAuth state token — substantial
  new design surface left as a follow-up. The browser-side page is the
  immediate substitute the user sees right after the OAuth redirect.
  Display name is HTML-encoded; ops/programmatic error paths keep their
  JSON shape.

Subject: [PATCH 019/113] Address PR #569 review (codex P1 + eanzhao): legacy
 default + suppress live streaming
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two regressions flagged after the initial commit landed:

1. SkillRunnerGAgent.cs:834 — actors created before proto field 16 existed replay
   an init event whose RequiresNyxidProxySuccess deserializes as false, so the
   safety net stays off post-deploy and the fix's reach depends on creation time
   rather than template semantics. ApplyInitialized now ORs the explicit flag with
   RequiresProxySuccessByTemplate(template_name), which returns true for
   "daily_report". Future fetch-and-summarize templates need to be added there.

2. SkillRunnerGAgent.cs:351 — the guard runs after ChatStreamAsync, but the
   streaming sink POSTs/PUTs each delta to Lark live during the stream. A
   hallucinated daily report would land in chat before EnsureToolStatusAllowsCompletion
   could fire, and each retry would repost it. TryCreateStreamingSink now
   short-circuits to null when State.RequiresNyxidProxySuccess is set, so chunked
   dispatch (which only fires after the guard) is the only path to Lark for those
   skills. Trade-off: fetch-and-summarize skills no longer stream live; the
   message lands as a one-shot POST after verification.

Tests:
- RequiresProxySuccessByTemplate_DerivesDefaultFromTemplateName — Theory pinning
  the template-name allowlist (case-sensitive).
- HandleInitializeAsync_DailyReportLegacyEvent_DerivesProxySuccessRequiredFromTemplate —
  integration test: command with explicit flag=false + template=daily_report
  produces State.RequiresNyxidProxySuccess=true (legacy event replay path).
- HandleInitializeAsync_NonFetchTemplate_DoesNotDeriveProxySuccessFromTemplate —
  guards against the helper false-flagging future pure-LLM templates.
- TryCreateStreamingSink_WhenRequiresNyxidProxySuccess_ReturnsNull — reflection-
  based pin that the streaming path is suppressed for daily_report runs.

Subject: [PATCH 020/113] Address PR #570 review: P1 preserve fields + drop
 operator-overrides + validation hardening
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PR #570 review consensus across codex / gemini / glm-5.1 / kimi /
mimo-v2.5-pro / v4-pro plus a P1 from codex on HandleProvision.

Changes:
- HandleProvision (P1): empty cmd.RedirectUri / cmd.OauthScope now
  preserves existing state instead of clobbering with "". Pre-fix a
  legacy / pre-redirect_uri caller (operator scripts that only know
  client_id + authority) would clear those fields and the next
  bootstrap pass would observe drift and re-DCR the freshly-pinned
  client.
- Rebuild endpoint: drops `redirect_uri` and `oauth_scope` from
  the request body. Endpoint always uses NyxIdRedirectUriResolver
  + AevatarOAuthClientScopes.AuthorizationScope. Pre-fix, an operator
  could pass a redirect_uri that differed from the resolver, the
  endpoint would persist and confirm it via the wait loop, and the
  next bootstrap pass would still re-DCR — reintroducing the wedge
  this PR fixes. Removing the override eliminates both the drift bug
  and the URL-validation surface (Uri.TryCreate / scheme check) the
  reviewers flagged.
- Validates client_id_issued_at_unix via DateTimeOffset.FromUnixTimeSeconds
  before dispatch — unbounded values (e.g. long.MaxValue) would
  otherwise crash AevatarOAuthClientProjectionProvider.GetAsync on
  the next status-endpoint poll.
- ConstantTimeEquals: removes the `right is null` early return so the
  helper has uniform timing across input shapes. Documents the
  residual length-leak as acceptable for a high-entropy admin token.
- Tightens RebuildObservationTimeout from 30s to 15s so the happy
  path stays comfortably under typical reverse-proxy idle-timeout
  budgets (Cloudflare 100s, AWS ALB 60s, stricter corporate proxies
  30s).
- Adds a comment near the actor.HandleEventAsync dispatch noting the
  shape mirrors AevatarOAuthClientBootstrapService and deliberately
  skips DCR mediation; future refactor extracting both behind an
  IAevatarOAuthClientAdminService is tracked as a follow-up.
- Tests: drops `Returns400_WhenOauthScopeMissingCanonicalScopes`
  (no longer reachable), adds `Returns400_WhenIssuedAtUnixOutOfRange`,
  asserts dispatched command's redirect_uri/oauth_scope come from
  resolver/canonical, asserts runtime.Captured.HaveCount(1) on the
  202 timeout path, and adds an actor-level test pinning that empty
  cmd fields preserve existing state.

Skipped: the response-shape trim (broker_capability_observed) — kept
for parity with /api/oauth/aevatar-client/status so ops can verify
the rebuild result with the same vocabulary.

Subject: [PATCH 029/113] Always advertise ornn_search_skills tool to LLM

OrnnAgentToolSource previously skipped tool registration when Ornn:BaseUrl was
unset. With mainnet helm not injecting that key, the LLM lost the typed entry
point and resorted to nyxid_proxy path-guessing (issue #530, multi-round 404
walks before stumbling on /api/web/skill-search).

OrnnOptions now defaults to the production base URL; deployments override via
configuration as before. The DI gate is the EnableOrnnSkills feature flag, not
configuration presence, so ornn_search_skills is always reachable from the
model regardless of deployment-side wiring.

Subject: [PATCH 030/113] Drop per-turn Ornn skill autoload pipeline

NyxIdConversationReplyGenerator carried ~350 lines of skill autoload logic
(name-extraction regexes, three-stage search/fetch pipeline, system-prompt
instruction injection) that ran on every Lark turn. The same effect is already
achievable through the LLM-driven path: ornn_search_skills lets the model
search, use_skill (backed by IRemoteSkillFetcher) lets it load on demand. The
autoload duplicated those facets via a parallel IRemoteSkillDiscovery
abstraction and stuffed full SKILL.md bodies into the system prompt every
turn, paying ~8s of pre-LLM latency and ~36KB of context window for content
the model frequently did not need.

Removed:
  * IRemoteSkillDiscovery / OrnnRemoteSkillDiscovery (parallel-track abstraction)
  * NyxIdChatOptions (autoload-only knobs; no remaining consumers)
  * Per-turn skill name extraction, slug heuristics, network-inventory keyword
    expansion, and auto-loaded instruction prompt section
  * Lark-only auto-loading scope cap

Kept:
  * IRemoteSkillFetcher / OrnnRemoteSkillFetcher (powers use_skill on demand)
  * SkillRegistry, UseSkillTool, ornn_search_skills

Result: ConversationReplyGenerator drops from 967 to ~310 lines and skill
discovery is now uniform across all channels rather than Lark-only.

Subject: [PATCH 031/113] Sharpen Ornn skill discovery prompts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With per-turn autoload removed, the LLM-driven path is the sole route to skill
selection. The prompts now explicitly tell the model to call
ornn_search_skills BEFORE nyxid_proxy / nyxid_search_capabilities for
specialized tasks, and list the trigger conditions (quoted name, slug-like
identifier, named domain workflow, "挂载/use/load this skill" intent).

Without this, weaker models defaulted to nyxid_proxy path-guessing — the
silent-fallback symptom called out in issue #530.

Updates:
  * OrnnSearchSkillsTool.Description: list specific triggers + relative
    priority over generic service-API discovery
  * Skills/system-prompt.md: explicit ordering — Ornn skill discovery first,
    raw service APIs as fallback only

+You have access to skills — specialized instruction packages for tasks like translation, content generation, data analysis, code review, network/device discovery, and domain workflows. The user's Ornn library is the source of truth; this prompt does not enumerate it.
 
-### Proactive Skill Discovery
+### Discovery Order (CRITICAL)
 
-**Proactively search for relevant skills** when the user's request involves a specialized task:
-1. Call `ornn_search_skills` with relevant keywords to check for matching skills
-2. If found, load with `use_skill` and follow its instructions
-3. If no match, proceed with general capabilities
+Before any `nyxid_proxy` / `nyxid_search_capabilities` call for a specialized task, run skill discovery first:
 
-### Using Skills
-- **Search**: `ornn_search_skills` with keywords
-- **Activate**: `use_skill` with the skill name
-- **Follow**: Once loaded, follow the skill's instructions
-- **Explicit requests**: If user says "挂载/mount/use" a skill, load it immediately
+1. **Always call `ornn_search_skills`** when ANY of these is true:
+   - User quotes a skill name (`'translate-pro'`, `"sg-office-network"`)
+   - User uses a slug-like or Title Case identifier that could be a skill (`my-skill`, `SG Office Network`)
+   - User asks for a specialized capability (translation, summarization, network/device inventory, scraping, scheduling, content drafting, code review, etc.)
+   - User says "挂载/mount/use/load this skill" or names a domain workflow
+2. If `ornn_search_skills` returns a match → call `use_skill` with the skill name and follow its instructions before any other tool call.
+3. Only if no match is found do you fall back to `nyxid_proxy` / `nyxid_search_capabilities` for raw service APIs.
+
+This order matters: skills are curated, named, and stable; service-API discovery via path-guessing is slow and noisy.
+
+### Quick Reference
+
+- **Search**: `ornn_search_skills` — query keywords or skill name; supports `scope=public|private|mixed`.
+- **Activate**: `use_skill` — pass the skill name returned by search; loads instructions + associated files.
+- **Follow**: Once loaded, treat the skill's instructions as authoritative for the user's task.
 
 ### Already Available Skills

Subject: [PATCH 032/113] Route Ornn skill API calls through NyxID proxy
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Production Ornn deployment at https://ornn.chrono-ai.fun serves only the SPA
shell — every /api/web/* path returns HTTP 200 with index.html. The direct
HTTP path in OrnnSkillClient deserialized that HTML as JSON and threw on the
first byte ('<' is an invalid start of a value), so ornn_search_skills always
failed with a confusing JSON parse error in mainnet.

The same calls succeed via NyxID's proxy
(POST {NyxID}/api/v1/proxy/s/ornn-api/api/web/...) because NyxID resolves the
upstream Ornn backend from the user's bound service rather than relying on
the public frontend hostname. That path was already proven by the
nyxid_proxy fallback the LLM was using before issue #530.

Refactor:
  * OrnnSkillClient now takes NyxIdApiClient + an OrnnOptions.NyxIdSlug
    (default ornn-api). All skill search and skill JSON fetches route through
    NyxIdApiClient.ProxyRequestAsync.
  * OrnnOptions.BaseUrl is removed; the upstream URL is no longer aevatar's
    concern. AevatarAIFeatureOptions.OrnnBaseUrl and the Workflow host wiring
    that propagated `Ornn:BaseUrl` are deleted.
  * AddOrnnSkills no longer requires a configure callback (the slug default
    fits 99% of deployments).
  * CLI's `aevatar app ornn skills` uses the same NyxID-proxied client; takes
    `--nyxid-url` (defaults to https://nyx-api.chrono-ai.fun) instead of the
    now-meaningless `--ornn-url`.
  * Tests rewritten against NyxIdApiClient + OrnnTestHttpMessageHandler at
    the HttpClient layer; new test pins the NyxID-proxy error envelope path.

Refs: #530

Subject: [PATCH 033/113] Default Ornn NyxID slug to canonical 'ornn'
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Mainnet logs after the previous NyxID-routing commit show NyxID returning 404
for slug 'ornn-api' — the upstream catalog entry chrono-ornn publishes is
slug 'ornn' (category=internal, requires_credential=false), confirmed in
chrono-ornn/ornn-core-skills/*/SKILL.md examples. The earlier 'ornn-api' guess
was inferred from issue #530's nyxid_proxy log lines, but that path was a user-
specific UserService binding rather than the canonical catalog name.

Changes:
  * OrnnOptions.NyxIdSlug default flips from 'ornn-api' to 'ornn'
  * AevatarAIFeatureOptions.OrnnNyxIdSlug + Aevatar:Ornn:NyxIdSlug config let
    deployments override when their NyxID catalog re-registered the service
    under a different name
  * 404 from the proxy now surfaces a slug-binding hint to the LLM
    ("NyxID has no service bound to slug 'X' — connect via nyxid_services
    action=create, or override Aevatar:Ornn:NyxIdSlug") so the model can
    guide the user instead of retrying mechanically
  * Tests updated to the new default slug + new 404 hint assertion

Refs: #530

Subject: [PATCH 034/113] Cap and throttle streaming Lark edits to avoid 230072
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Mainnet logs show Lark refuses message edits at code 230072 ("The message has
reached the number of times it can be edited") on this tenant after roughly
20 edits per message. The previous TurnStreamingReplySink had two issues that
together blew through that cap on long replies and left users staring at a
half-finished response:

1. DispatchLoopAsync drained _pendingText at network round-trip pace (~50ms)
   without re-checking _throttle. Once a dispatch was in flight and any
   token-driven FlushAsync stashed text, the loop iterated immediately on
   the next chunk, ignoring the configured 750ms throttle. Streaming token
   bursts produced one Lark edit per token.

2. There was no hard ceiling on interim edits. Even with a working throttle,
   long tool-iterating replies could exceed Lark's per-message edit cap, and
   the final flush would then fail with the same 409 — leaving the last
   successful interim chunk as the user's terminal text (truncation).

Changes:

  * Loop throttle gate: when DispatchLoopAsync finishes a dispatch and finds
    pending text, it checks elapsed since _lastEmitAt. If the throttle window
    is not yet open, the loop arms the deferred flush timer (same path
    OnFlushTimerFired uses) and exits, so caller-driven OnDeltaAsync isn't
    blocked on the throttle either.

  * Interim chunk cap: NyxIdRelayOptions.StreamingMaxInterimChunks (default 15)
    bounds the number of interim edits per turn. Once reached, additional
    interim flushes stash the latest text but skip dispatch. FinalizeAsync
    bypasses the cap so the final edit always lands — long replies freeze on
    the last interim until the final fires, which beats truncation.

  * Tests: regression coverage for both gates (DispatchLoop_StashesDuring*

Subject: [PATCH 035/113] Move NyxID manual to Ornn skill and add 5-min TTL on
 remote skill cache
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The NyxID-detail sections of system-prompt.md (account/services/MFA/sessions,
service connection flows, OAuth/device-code/API-key recipes, notifications,
nodes, error codes — about 200 lines) duplicate the curated `nyxid` skill on
Ornn. Maintaining them in this prompt forces a redeploy every time the NyxID
manual evolves. The same content is reachable at runtime via
`use_skill(skill="nyxid")`, so the prompt now points there instead.

The aevatar-internal sections (channel_registrations, agent_delivery_targets,
agent_builder slash commands, /route /model selection) stay in the prompt
because they are not on Ornn — they describe state local to this aevatar
deployment.

Cache invalidation: SkillRegistry now records a FetchedAt timestamp per entry
and TryGet accepts an optional maxAge. UseSkillTool passes 5 minutes, so a
stale `nyxid` skill cached in-process is refetched from Ornn on the next
use_skill call after the window — curator updates land within 5 minutes
without a redeploy.

Local skills (scanned per-turn from disk) call TryGet without maxAge, so the
TTL check does not affect them.

-## Capability Tools (Doing Things)
+## Skills (CRITICAL — NyxID and Ornn knowledge lives here)
+
+This prompt deliberately keeps the NyxID and Ornn user manuals **out of the system prompt** and on the Ornn skill platform instead, so curators can update those manuals without redeploying the bot. You learn the canonical, up-to-date usage by loading the relevant skill.
+
+**Before doing any of the following, call `use_skill(skill="nyxid")` first** to load the authoritative NyxID manual:
+- Account / profile / MFA / sessions / consents
+- Service catalog browsing, connecting a new service (OAuth / device-code / API key flows)
+- API key, node, organization, approval, notification management
+- Diagnosing NyxID error codes (`approval_required`, `unauthorized`, `node_offline`, etc.)
+- Anything that would otherwise need `nyxid_account`, `nyxid_status`, `nyxid_profile`, `nyxid_mfa`, `nyxid_sessions`, `nyxid_catalog`, `nyxid_services`, `nyxid_endpoints`, `nyxid_external_keys`, `nyxid_api_keys`, `nyxid_nodes`, `nyxid_approvals`, `nyxid_notifications`, `nyxid_providers`, `nyxid_orgs`, `nyxid_admin`, `nyxid_search_capabilities`, `nyxid_proxy_execute`
+
+**Before driving the Ornn API directly via the AI Agent CLI, call `use_skill(skill="ornn-agent-manual-cli")`** to load the Ornn agent manual.
+
+`use_skill` caches the loaded instructions in-process for ~5 minutes; after that window the next call refetches from Ornn so curator updates land within 5 minutes without a redeploy.
+
+### Proactive skill discovery
+
+When the user mentions a named skill or asks for a specialized capability (translation, summarization, network/device inventory, scraping, scheduling, content drafting, code review, domain workflows, etc.), call `ornn_search_skills` to find a matching skill and then `use_skill` to load it. Treat the loaded skill's instructions as authoritative for that task.
+
+Triggers:
+- User quotes a skill name (`'translate-pro'`, `"sg-office-network"`)
+- User uses a slug-like or Title Case identifier that could be a skill name
+- User says "挂载/mount/use/load this skill" or names a domain workflow
+
+Only fall back to `nyxid_proxy` / generic API discovery when no skill matches.
+
+### Quick reference
+
+- **Search**: `ornn_search_skills` — keywords or skill name; `scope=public|private|mixed`
+- **Activate**: `use_skill skill="<name>"` — loads instructions + associated files
+- **Follow**: once loaded, the skill's instructions take precedence over generic guidance for that task

 ### Channel Bots — Messaging
 Use `nyxid_proxy` with a Telegram/Discord bot's slug to send messages. For Telegram: POST `/sendMessage` with `{"chat_id":"...","text":"..."}`.

 - `/model use <model-name>` — keep the current route and only override the model.
 - `/model reset` — clear the sender's route/model preference and fall back to the bot default.
 
-### Admin
-- **nyxid_admin** — Administrative commands (admin role required): manage invite codes (list, create, deactivate)
-
-### API Discovery (Fallback)
-- **nyxid_search_capabilities** — Search NyxID API capabilities by natural language query. Returns matching operations with method, path, and parameters. Use this to discover endpoints not covered by specialized tools
-- **nyxid_proxy_execute** — Execute a NyxID API operation discovered via nyxid_search_capabilities. Validates parameters against cached OpenAPI spec before sending

-## Connecting New Services
-
-All connection info comes from the catalog entry. Use `nyxid_catalog action=show slug=<slug>` and read:
-
-| Field | Meaning |
-|-------|---------|
-| `provider_type` | Connection method: `oauth2`, `device_code`, `api_key` |
-| `credential_mode` | Who provides OAuth app: `admin` (platform) or `user` (user must provide) |
-| `provider_config_id` | Provider ID for OAuth/device-code |
-| `api_key_instructions` | How to get an API key (display as-is) |
-| `api_key_url` | Where to get the key (clickable link) |
-| `requires_gateway_url` | If true, user must also provide endpoint URL |
-
-### OAuth Flow
-1. Check `nyxid_providers action=list` for existing connection
-2. If `credential_mode=user`: check/set credentials via `nyxid_providers action=get_credentials/set_credentials`
-   - Callback URL: `https://nyx-api.chrono-ai.fun/api/v1/providers/callback`
-3. `nyxid_providers action=connect_oauth provider_id=<id>` → give user the authorization URL
-4. Verify with `nyxid_providers action=list`
-
-### Device Code Flow
-1. `nyxid_providers action=connect_device_code provider_id=<id>` → tell user to visit URL and enter code
-2. Poll: `nyxid_providers action=poll_device_code provider_id=<id> state=<state>`
-3. Verify with `nyxid_providers action=list`
-
-### API Key Flow
-1. Guide user with catalog's `api_key_instructions` and `api_key_url`
-2. `nyxid_services action=create service_slug=<slug> credential=<token> label=<name>`
-3. Test with a simple read-only proxy request
-
-If user asks to connect a service and you don't know the slug, browse with `nyxid_catalog action=list`.

-## Channel Bot Setup (Lark via Nyx Relay)
+### channel_registrations (Aevatar's local Lark mirror)
 
 Aevatar owns the local runtime and registration mirror.
 For Lark, webhook ingress goes through NyxID first, then NyxID relays callbacks into Aevatar.
 Nyx owns the platform bot, route, and relay API key; Aevatar owns the local registration mirror used by the runtime.
 Do not assume `channel_registrations action=list` being empty means the Nyx bot is missing.
 
-### Lark Stage 1: New provisioning
-
-Use this stage when the user wants the bot connected for inbound Lark messages and basic relay replies.
-Do not block this stage on typed Lark tools, delivery target bindings, or proactive outbound setup.
-
-Register channel bot in Aevatar:
+**Stage 1: New provisioning** — when the user wants the bot connected for inbound Lark messages and basic relay replies. Do not block on typed Lark tools or proactive outbound setup.
 
 `channel_registrations action=register_lark_via_nyx app_id=<app_id> app_secret=<app_secret> verification_token=<verification_token when available> webhook_base_url=https://<your-aevatar-host>`
 
-`verification_token` is optional in the tool contract, but when the user has it or the Nyx backend requires it, pass it through.
-
-→ This returns the registration ID, the Nyx relay callback URL, and the Nyx webhook URL that must be configured in the Lark developer console.
-
-Configure the platform webhook:
-
-**Lark/Feishu:** 开发者后台 → 事件与回调 → 事件配置 → 请求地址:
-`<webhook_url returned by register_lark_via_nyx>`
-
-Add events:
-- `im.message.receive_v1`
-- `card.action.trigger`
-
-### Lark Stage 2: Repair an existing bot
+→ Returns the registration ID, the Nyx relay callback URL, and the Nyx webhook URL that must be configured in 开发者后台 → 事件与回调 → 事件配置 → 请求地址.
 
-Use this stage when Nyx already has the Lark bot and route, but Aevatar no longer replies or `channel_registrations action=list` is empty.
+Add events: `im.message.receive_v1`, `card.action.trigger`.
 
-First try rebuilding the local registration read model from the authoritative actor state:
+**Stage 2: Repair an existing bot** — when Nyx already has the Lark bot/route but Aevatar no longer replies or `channel_registrations action=list` is empty.
 
-`channel_registrations action=rebuild_projection`
+1. `channel_registrations action=rebuild_projection` — rebuild local read model from authoritative actor state.
+2. Inspect Nyx-side first: `nyxid_channel_bots action=list` / `show` / `routes`. (For NyxID-side details, `use_skill(skill="nyxid")`.)
+3. If Nyx is healthy but local list still empty, restore the local mirror:
+   `channel_registrations action=repair_lark_mirror registration_id=<old> credential_ref=<existing_when_needed> webhook_base_url=https://<aevatar-host> nyx_channel_bot_id=<id> nyx_agent_api_key_id=<id> nyx_conversation_route_id=<id>`
+   `repair_lark_mirror` must preserve the existing relay credential reference. Reuse `registration_id` when its `vault://.../relay-hmac` secret still exists, or pass `credential_ref` explicitly. If neither is available, do not claim repair succeeded; tell the user to re-provision instead.
 
-Inspect the Nyx side first:
+**Stage 3: Advanced Lark capabilities** — only when the user needs proactive sends, typed Lark tools, delivery target bindings, spreadsheet appends, approval actions, or active chat lookup. Ensure NyxID has a usable Lark outbound provider slug (typically `api-lark-bot`); if not, `use_skill(skill="nyxid")` to drive the catalog connection flow.

-- `nyxid_channel_bots action=show id=<channel_bot_id>`
-- `nyxid_channel_bots action=routes channel_bot_id=<channel_bot_id>`
-- `nyxid_api_keys action=show id=<agent_api_key_id>`
+For advanced Lark API operations outside the current relay reply, prefer typed tools: `lark_messages_send`, `lark_messages_search`, `lark_messages_batch_get`, `lark_messages_reactions_list`, `lark_messages_reactions_delete`, `lark_chats_lookup`, `lark_sheets_append_rows`, `lark_approvals_list`, `lark_approvals_act`. Fall back to `nyxid_proxy_execute` only when typed tools don't cover.
 
-If the Nyx bot, route, and relay callback are correct but rebuild did not restore the local list, restore the local Aevatar mirror:
+For inbound Lark relay turns that represent a fresh user message, do **not** call `lark_messages_reply`, `lark_messages_react`, or `nyxid_proxy_execute` to deliver the answer. Produce the final text reply directly; the channel runtime will send it through the Nyx relay reply token.

+Managing registrations: `list`, `rebuild_projection`, `repair_lark_mirror`, `delete id=<reg_id> confirm=true`.
 
-`repair_lark_mirror` must preserve the existing relay credential reference. Reuse the old `registration_id` when its `vault://.../relay-hmac` secret still exists, or pass `credential_ref` explicitly. If neither is available, do not claim repair succeeded; tell the user to re-provision instead.
+### agent_delivery_targets
 
-If rebuild and mirror repair both succeed but `channel_registrations action=list` still stays empty, tell the user the local Aevatar registration projection/read model is unhealthy.
+Workflow `human_approval`, `human_input`, `secure_input` steps can send Feishu delivery messages when the workflow step includes `delivery_target_id=<agent_id>`. For the Nyx relay path, these arrive as interactive cards in Lark/Feishu (with `/approve`, `/reject`, `/submit` as fallback commands).
 
-### Lark Stage 3: Advanced Lark capabilities
+Bind `agent_id` to the real outbound route:
+- `agent_delivery_targets action=list`
+- `agent_delivery_targets action=upsert agent_id=<agent_id> conversation_id=<chat_id> nyx_provider_slug=<lark_slug, e.g. api-lark-bot> nyx_api_key=<key>`
+- `agent_delivery_targets action=delete agent_id=<agent_id> confirm=true`
 
-Only use this stage when the user needs proactive sends, typed Lark tools, delivery target bindings, spreadsheet appends, approval actions, or active chat lookup.
+`channel_registrations` configures inbound bot callbacks; `agent_delivery_targets` configures outbound agent delivery. Today the human-interaction delivery path supports `lark`.
 
-Ensure NyxID has a usable Lark outbound provider slug, typically `api-lark-bot`:
-`nyxid_services action=list` → check if the service exists
-If not: `nyxid_catalog action=list` → find the slug → guide user to add it
+### agent_builder (Day One persistent automation)
 
-For advanced Lark API operations that are not the current inbound relay reply, prefer typed tools such as:
-- `lark_messages_send`
-- `lark_messages_search`
-- `lark_messages_batch_get`
-- `lark_messages_reactions_list`
-- `lark_messages_reactions_delete`
-- `lark_chats_lookup`
-- `lark_sheets_append_rows`
-- `lark_approvals_list`
-- `lark_approvals_act`
+Use when the user wants a persistent Day One automation agent in Feishu private chat. Creation is private-chat only; if the current chat is not `p2p`, tell the user to DM the bot.
 
-Only call `lark_messages_reply` or `lark_messages_react` when the user explicitly asks you to reply to or react to a specific Lark message outside the current relay turn.
+**Always speak to the user using slash commands**, never the internal template names. `daily_report` and `social_media` are tool-argument identifiers, not user vocabulary.
 
-Use generic `nyxid_proxy_execute` only when typed tools do not cover the operation.
-
-For inbound Lark relay turns that represent a fresh user message, do not call `lark_messages_reply`, `lark_messages_react`, or `nyxid_proxy_execute` to deliver the answer. Produce the final text reply directly; the channel runtime will send it through the Nyx relay reply token.
-
-When binding workflow delivery or proactive agent delivery, use a Lark outbound provider slug such as `api-lark-bot`.

-
-## Agent Delivery Targets
-
-Workflow `human_approval`, `human_input`, and `secure_input` steps can send Feishu delivery messages when the workflow step includes `delivery_target_id=<agent_id>`.
-
-For the Nyx relay path, these arrive as interactive cards in Lark/Feishu:
-- `human_approval`: users can approve/reject directly from the card; `/approve ...` and `/reject ...` remain valid fallback commands
-- `human_input` / `secure_input`: users can submit directly from the card; `/submit ...` remains a valid fallback command
-
-Use `agent_delivery_targets` to bind that `agent_id` to the real outbound route:
-- List: `agent_delivery_targets action=list`
-- Upsert: `agent_delivery_targets action=upsert agent_id=<agent_id> conversation_id=<chat_id> nyx_provider_slug=<lark_provider_slug such as api-lark-bot> nyx_api_key=<api_key>`
-- Delete: `agent_delivery_targets action=delete agent_id=<agent_id> confirm=true`
-
-Notes:
-- `channel_registrations` configures inbound bot callbacks
-- `agent_delivery_targets` configures outbound agent delivery
-- Today the human interaction delivery path supports `lark`

-## Agent Builder
-
-Use `agent_builder` when the user wants a persistent Day One automation agent in Feishu private chat.
-
-### User-facing vocabulary (critical)
-
-When you describe Day One to the user — capability summaries, suggested replies, example commands, help text — use the slash commands below, **not** the internal template names. `daily_report` and `social_media` are tool-argument identifiers; they are not commands the user types.

-## Notifications & Approvals
-
-If a proxy request requires approval:
-1. Tell user approval is pending
-2. User approves via Telegram notification, NyxID mobile app, or `nyxid_approvals action=approve id=<id>`
-
-Setup notifications: `nyxid_notifications action=telegram_link` / Mobile app: https://nyxid.onelink.me/REzJ/dql9w8fx

-## Node Agents
-
-Nodes keep credentials on user's infrastructure. NyxID routes requests through WebSocket.
-- Register: `nyxid_nodes action=register_token name=<name>` → install CLI → `nyxid node register` → `nyxid node daemon install`
-- Route service: `nyxid_services action=route id=<id> node_id=<node_id>`

-## Error Handling
-
-| Error Code | Action |
-|------------|--------|
-| `approval_required` (7000) | Tell user to check approvals |
-| `approval_failed` (7001) | Retry or check notification setup |
-| `unauthorized` (1001) | User needs to re-login |
-| `node_offline` (8001) | Check node status |

 ## Working Rules
 
-- **Be proactive and autonomous**: DO IT immediately, don't ask for confirmation
-- **Probe unknown services**: Try `GET /openapi.json`, `GET /docs`, or `GET /api` to discover endpoints
-- Always check `<connected-services>` before assuming a slug exists
-- Keep request bodies minimal and service-correct
-- Credentials the user pastes to configure a service (App ID, App Secret, API key, token, Verification Token) are expected input — accept them and call the right tool (`nyxid_providers action=set_credentials`, `nyxid_services action=create`, `nyxid_external_keys`, `channel_registrations`). NyxID web cannot configure most providers, so chat is the required path. Never refuse citing "secret leakage" or ask the user to redact.
+- **Be proactive and autonomous**: DO IT immediately, don't ask for confirmation.

-- When something fails, check the error and try alternatives before asking the user
-- Connect services in-chat using the catalog-driven flow
-- Read all guidance from the catalog entry — don't hardcode service-specific instructions
+- When something fails, check the error and try alternatives before asking the user.

-## Skills
-
-You have access to skills — specialized instruction packages for tasks like translation, content generation, data analysis, code review, network/device discovery, and domain workflows. The user's Ornn library is the source of truth; this prompt does not enumerate it.
-
-### Discovery Order (CRITICAL)
-
-Before any `nyxid_proxy` / `nyxid_search_capabilities` call for a specialized task, run skill discovery first:
-
-1. **Always call `ornn_search_skills`** when ANY of these is true:
-   - User quotes a skill name (`'translate-pro'`, `"sg-office-network"`)
-   - User uses a slug-like or Title Case identifier that could be a skill (`my-skill`, `SG Office Network`)
-   - User asks for a specialized capability (translation, summarization, network/device inventory, scraping, scheduling, content drafting, code review, etc.)
-   - User says "挂载/mount/use/load this skill" or names a domain workflow
-2. If `ornn_search_skills` returns a match → call `use_skill` with the skill name and follow its instructions before any other tool call.
-3. Only if no match is found do you fall back to `nyxid_proxy` / `nyxid_search_capabilities` for raw service APIs.
-
-This order matters: skills are curated, named, and stable; service-API discovery via path-guessing is slow and noisy.
-
-### Quick Reference
-
-- **Search**: `ornn_search_skills` — query keywords or skill name; supports `scope=public|private|mixed`.
-- **Activate**: `use_skill` — pass the skill name returned by search; loads instructions + associated files.
-- **Follow**: Once loaded, treat the skill's instructions as authoritative for the user's task.
-
 ### Already Available Skills
 
 Skills listed at the end of this prompt (when present) are already loaded and ready to invoke via `use_skill`. Match the user's intent to those descriptions before searching.

Subject: [PATCH 036/113] Refactor Nyx relay streaming runtime state into phase
 machine

Replace the ad-hoc Disabled + SuppressInterim booleans on
NyxRelayStreamingState with a NyxRelayStreamingPhase enum (Idle /
PlaceholderSent / Streaming / SuppressingInterim / DisabledPreSend /
TerminalSucceeded / TerminalPartial), a transition validator that
logs warn on illegal transitions instead of throwing (actor turns
must keep making progress), and a TerminalReason captured on entry
to terminal phases for diagnostics.

Add a single ShouldSkipNyxRelayStreamingForUnavailable guard so every
streaming entry point (HandleLlmReplyStreamChunkAsync,
TryCompleteStreamedReplyAsync, future tool-call/reasoning hooks)
defers to one helper instead of repeating ad-hoc Disabled-or-X
checks. Replace direct field reads with phase-level helpers
AllowsInterimEdit / AllowsFinalEdit / AllowsReplyFallback.

Behavior unchanged: 125 Channel.Protocol tests and 36 ChannelRuntime
streaming sink tests continue to pass. Lays the groundwork for the
CardKit streaming sink to extend the same phase machine with
Creating / Terminated / CreationFailed phases.

Subject: [PATCH 037/113] Fix Lark bot tool calls: align Ornn paths, sandbox
 path, slug

The bot LLM stalled on tool calls because three upstream contracts
were wrong, leaving the user staring at a loading reaction:

- OrnnSkillClient hit /api/web/skill-search and /api/web/skills/.../json,
  but chrono-ornn exposes routes under /api/v1. Switched to /api/v1.
- NyxIdCodeExecuteTool POSTed { language, code } to /run, but
  chrono-sandbox-service only exposes /execute and expects
  { language, script }. Renamed and re-pathed.
- Mainnet appsettings did not override Aevatar:Ornn:NyxIdSlug, so the
  bot fell back to the canonical default "ornn" while production
  registered the service as "ornn-api". Added explicit override.

Verified the corrected path/slug end-to-end via `nyxid proxy request
ornn-api api/v1/skill-search` and the chrono-sandbox /openapi.json.

Subject: [PATCH 038/113] Add LarkCardKitClient for streaming-card endpoints

Wraps Lark CardKit 2.0 REST endpoints (/open-apis/cardkit/v1/...)
through the existing NyxID API-key proxy: card create, element-content
streaming (PUT, sequence-ordered), settings patch (close streaming
mode), full card replace.

Mirrors LarkNyxClient's shape: typed DTOs, raw JSON responses,
ProviderSlug from LarkToolOptions, NyxIdApiClient.ProxyRequestAsync
underneath. Streaming sink consumers parse the response themselves.

Required Lark scopes: cardkit:card:read + cardkit:card:write (already
granted on the aevatar bot). NyxID proxy is wildcard so no NyxID
changes are needed.

No callers yet; wired in for the upcoming TurnStreamingCardSink work.

Subject: [PATCH 039/113] Add ssh_exec tool and timeout-budgeted LLM reply
 fallback
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Lark bot incident exposed two related gaps the LLM had to navigate:

1. SSH-typed services (e.g. sg-office-network registered as ssh://host:port)
   could only be reached via the generic HTTP nyxid_proxy tool, which always
   502s because NyxID does not HTTP-proxy SSH endpoints. The LLM kept guessing
   /exec, /ssh/exec, /health for nothing. Add a dedicated ssh_exec tool that
   wires through NyxID's POST /api/v1/ssh/{slug}/exec contract — same Bearer
   token, structured { command, principal, timeout_secs } body, mirroring
   `nyxid ssh exec`. RequiresApproval=true since it can mutate the remote.

2. ChannelLlmReplyInboxRuntime.ProcessAsync passed CancellationToken.None to
   the LLM run. When all tools failed and the model kept retrying (or one tool
   actually hung), the inbox task ran indefinitely past the relay's 120s
   ResponseTimeoutSeconds, leaving Lark stuck on the loading reaction with no
   final reply ever sent. Cap each turn at the same relay budget via a
   timeout CancellationTokenSource and fold the resulting OperationCanceled
   into a user-visible fallback (errorCode=llm_reply_timeout, generic apology
   text) routed through the same LlmReplyReadyEvent path the existing throw/
   empty-reply branches already use.

Tests:
- NyxIdSshExecToolTests: route + body shape, missing-field guard, default
  and clamped timeout, missing-token guard.
- ChannelLlmReplyInboxRuntimeTests: HangingReplyGenerator that only completes
  on cancellation; assert TerminalState=Failed, ErrorCode=llm_reply_timeout,
  non-empty Outbound.Text under a 1s ResponseTimeoutSeconds budget.

Subject: [PATCH 040/113] Add LarkCardStreamingPhase machine for upcoming card
 sink

Distinct from NyxRelayStreamingPhase: card streaming has its own
lifecycle (Idle / Creating / Streaming / Completed / Aborted /
Terminated / CreationFailed) and goes through the API-key proxy
rather than channel-relay. Uses the same partial-class layout +
TransitionLarkCardStreamingPhase / ShouldSkipLarkCardStreamingForUnavailable
helpers as the NyxRelay counterpart so call-sites read uniformly.

Pre-flight fallback shape: AllowsTextEditFallback covers Idle and
CreationFailed; the dispatcher uses this to pick between card sink
and the legacy text-edit sink before chunks flow. Once Streaming is
reached, the card path owns the turn.

State carries CardId, CardMessageId, OriginalCardId (reserved for the
mid-stream-fallback follow-up), monotonic Sequence, StreamingElementId
(default streaming_main), LastFlushedText, and TerminalReason. Cleared
alongside reply tokens via RemoveNyxRelayReplyToken.

No callers yet; wired in for the upcoming card runner + sink.

Subject: [PATCH 041/113] Add IConversationCardTurnRunner contract for CardKit
 streaming
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three operations match the CardKit lifecycle: RunCardCreateAsync
(card.create + im.messages send + first content write),
RunCardStreamAsync (subsequent element-content updates with explicit
sequence), and RunCardFinalizeAsync (close streaming mode + optional
final content write). The grain owns LarkCardStreamingState and
pre-increments sequence before each call.

Result types include classification flags (IsRateLimited / IsTableLimit
Exceeded / IsCardUnavailable) so the grain can branch fallback decisions
without parsing error-code strings: rate-limit → skip frame and retry,
table-limit → fall back to text-edit sink for the rest of the turn,
unavailable → terminate at LarkCardStreamingPhase.Terminated.

NullConversationCardTurnRunner default reports a transient failure on
every operation so the grain naturally falls back to the text-edit sink
when CardKit DI isn't wired (or the bot scope isn't granted).

Production impl lands in the next commit.

Subject: [PATCH 042/113] Allowlist HangingReplyGenerator polling wait in
 channel runtime tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Base branch (feature/lark-bot) added a HangingReplyGenerator test double
using Task.Delay(Timeout.Infinite, ct) to verify runtime cancels reply
generation on timeout. Same legitimate pattern as the existing
VoiceTransportRelayTests entry — there's no deterministic completion
signal because the test is checking cancellation behavior itself.

Subject: [PATCH 043/113] Add ChannelCardConversationTurnRunner for CardKit
 outbound

Production IConversationCardTurnRunner impl. Composes
ILarkCardKitClient (cardkit/v1/* endpoints) with
ILarkNyxClient.SendMessageAsync (im/v1/messages with msg_type=
interactive) to drive create -> send -> stream -> finalize:

- RunCardCreateAsync: card.create with empty streaming element ->
  send interactive message referencing card_id -> first
  cardElement.content write at sequence=1.
- RunCardStreamAsync: cardElement.content with grain-supplied
  sequence and a deterministic uuid for safe retry.
- RunCardFinalizeAsync: optional final cardElement.content write
  when finalText drifted from last interim, then card.settings
  patch closing streaming_mode (cursor disappears).

Token: bot owner's NyxID access token from
activity.TransportExtras.NyxUserAccessToken. Receive target:
nyx_lark_chat_id for groups/channels/threads (cross-app safe per
the proto's documented invariants), nyx_lark_union_id for p2p DMs.

Error classification surfaces Lark codes 230020 (rate-limited),
230099 / 11310 (table limit / unavailable), and 230100 (card
unavailable) so the grain can branch the fallback decision without
parsing error-code strings.

Default DI registers NullConversationCardTurnRunner from Channel.
Runtime; NyxidChat.ServiceCollectionExtensions then Replace()s it
with the real impl, mirroring how IConversationTurnRunner gets its
production binding. Adds Aevatar.AI.ToolProviders.Lark project
reference to NyxidChat and an InternalsVisibleTo so the runner can
reach LarkProxyResponseParser without exposing its result records
on the public surface.

Tighten interface: RunCardFinalizeAsync now takes the reference
ChatActivity so the runner can read the access token from
TransportExtras (the LlmReplyReady path doesn't carry a chunk).

No runtime callers yet - the actor still routes every chunk through
the text-edit handler. Sink selection lands next.

Subject: [PATCH 044/113] Resolve catalog_service_id for ssh_exec; default Ornn
 slug to ornn-api
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After deploying the previous fix, the production logs showed the LLM finally
trying ssh_exec but every call still 404'd, and the Ornn search tool was
still registered against slug "ornn" instead of "ornn-api". Two real bugs
behind that:

1. NyxID's POST /api/v1/ssh/{id}/exec keys on `catalog_service_id`, NOT on
   the user-service slug or its uuid. The CLI's `nyxid ssh exec` does the
   same hop internally (cli/src/commands/ssh.rs:resolve_ssh_service_id).
   Without that resolve, both 'sg-office-network' and its uuid 404 with
   NyxID's generic "Service not found" envelope. Tool now does
   GET /api/v1/keys/{slug-or-id} -> reads catalog_service_id, falls back to
   the /keys list when the direct endpoint omits it, and only then POSTs
   exec against the resolved id.

2. The mainnet ConfigMap deployed to the cluster carries its own
   appsettings.Distributed.json that ships without an Ornn section, so the
   in-repo override added in 5d09f916 never reached production — the bot
   kept reading the canonical default "ornn" while the registered slug is
   "ornn-api". Flip the OrnnOptions default so a deployment without an
   explicit override ends up at the right slug; deployments using a
   different name still set Aevatar:Ornn:NyxIdSlug.

Tests:
- NyxIdSshExecToolTests: replace the single-response handler with a
  path-routed PathHandler; new cases assert the slug -> catalog_service_id
  hop and the /keys list fallback path.
- ChannelLlmReplyInboxRuntimeTests + Ornn tests still pass (15 / 15).

Verified end-to-end: `curl -X POST .../api/v1/ssh/{catalog_id}/exec`
returns 200 with the SSH stdout payload while `.../ssh/{slug}/exec` 404s.

End-to-end CardKit path is now functional behind a config flag. With
StreamingCardKitEnabled=true the inbox runtime constructs the sink in
card mode (200ms throttle, no interim cap), the sink stamps every
chunk with card_mode=true, and the conversation actor branches into
the LarkCardStreamingPhase machine + IConversationCardTurnRunner for
both interim and finalize paths.

Wiring:

- proto: LlmReplyStreamChunkEvent gains a `card_mode` bool field.
  Default false preserves the existing edit-message path; sink
  populates it when CardKit is on.
- TurnStreamingReplySink: new cardMode constructor parameter; sets
  the proto bit on dispatched chunks. Throttle / interim-cap stay
  controlled by the existing parameters so the inbox runtime can
  pick CardKit-friendly defaults (200ms / no cap).
- ConversationGAgent.HandleLlmReplyStreamChunkAsync: card-mode
  branch routes through HandleLarkCardStreamingChunkCoreAsync. That
  method owns the entire CardKit lifecycle:
  Idle -> Creating -> Streaming on first chunk; Streaming self-loop
  on subsequent chunks (sequence pre-incremented per call). Returns
  false only when phase is CreationFailed so the caller falls back
  to the legacy edit-message path; otherwise returns true and the
  card path owns the chunk.
- Failure routing: card.create rate-limit / table-limit / scope
  errors transition CreationFailed -> caller falls through to
  edit-message sink for the rest of the turn (still has reply_token
  + receive_id from the same activity). Mid-stream rate-limit
  (230020) drops the frame; table-limit (230099 / 11310) terminates
  the turn at LarkCardStreamingPhase.Terminated with the last
  flushed text persisted as visible. No mid-stream fallback to
  edit-message in v1 — gate is "create succeeded vs not".
- TryCompleteStreamedReplyAsync defers to TryCompleteCardStreamed
  ReplyAsync first; that runs RunCardFinalizeAsync (optional
  trailing element-content write + PATCH /settings closing
  streaming_mode), persists ConversationTurnCompletedEvent with
  SentActivityId="lark-card-stream:{card_message_id}", and clears
  the card state. Falls through when the card path was never
  active, fell back to text-edit, or already terminated.
- NyxIdRelayOptions adds StreamingCardKitEnabled (default false) and
  StreamingCardKitFlushIntervalMs (default 200). Inbox runtime reads
  both when constructing the sink and bypasses
  StreamingMaxInterimChunks in card mode.

All 125 protocol tests + 36 channel-runtime streaming sink tests
still pass — card-mode codepath is dormant under the default flag.

Subject: [PATCH 046/113] Add card-mode streaming tests covering create,
 stream, finalize, fallback
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Mirrors the existing 17 NyxRelay streaming tests with seven card-mode
analogues, each exercising one observable behaviour of the
HandleLarkCardStreamingChunkCoreAsync + TryCompleteCardStreamedReplyAsync
paths through a RecordingCardTurnRunner mock:

- First chunk in card mode runs RunCardCreateAsync exactly once and
  does not yet call RunCardStreamAsync.
- Subsequent chunks run RunCardStreamAsync with monotonically
  incrementing Sequence (2, 3, 4, ...) — guards against the
  pre-increment-vs-post-increment regression that would replay
  sequence=1 forever.
- CardCreate rate-limit / table-limit transitions phase to
  CreationFailed and routes the chunk + every subsequent chunk
  through the legacy text-edit RecordingTurnRunner — confirms the
  fallback gate at the HandleLlmReplyStreamChunkAsync entry point.
- Mid-stream rate-limit (Lark 230020) drops the frame without
  consuming the sequence slot; the next chunk reuses the same
  sequence value so the runner sees the recovering write at the
  intended sequence.
- Mid-stream table-limit terminates the turn at Terminated phase;
  later chunks are guarded out and the runner is not invoked again.
- HandleLlmReplyReadyAsync on a Streaming card persists
  ConversationTurnCompletedEvent with SentActivityId starting
  "lark-card-stream:" — the new prefix that distinguishes the card
  path from the legacy "nyx-relay-stream:" prefix in observers.
- HandleLlmReplyReadyAsync after CreationFailed defers to the
  edit-message finalize path: card runner's RunCardFinalizeAsync
  is never invoked and the persisted SentActivityId carries the
  legacy prefix. Guards against TryCompleteCardStreamedReplyAsync
  swallowing the legitimate text-edit finalize when the card path
  fell back pre-flight.

CreateAgent now optionally accepts an IConversationCardTurnRunner;
omitting it falls back to NullConversationCardTurnRunner so the
existing 17 NyxRelay streaming tests stay unaffected.

Subject: [PATCH 047/113] Move CardKit streaming shell builder into Lark
 platform project

The channel-card-literal guard forbids raw Lark card JSON literals
(schema = "2.0", tag = "markdown", etc.) outside the composer's project.
The new ChannelCardConversationTurnRunner.BuildInitialCardJson tripped
that guard. Extract the shell builder into LarkStreamingCardShell within
the Lark platform project (which the guard exempts as the composer's
home), and call it from the runner.

Subject: [PATCH 048/113] Address PR #590 review: P2 hardening + boundary fixes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes the major / P2 items raised across the review:

* (codex P2) Restore the empty-PlatformMessageId guard in
  ShouldSkipNyxRelayStreamingForUnavailable's Finalize branch. The
  pre-refactor path explicitly bailed when state.PlatformMessageId
  was empty (Nyx returned an empty platform id on initial /reply);
  the phase-machine refactor dropped that check and could let final
  edits fire against null. Now `Finalize` short-circuits on either
  AllowsReplyFallback OR empty PlatformMessageId.

* (kimi P2) Drop ConfigureAwait(false) from the two new actor
  await points. Actor turns run on a single-threaded scheduler and
  subsequent state mutations on _nyxRelayStreamingStates / _larkCard
  StreamingStates must observe that context.

* (mimo P2) Strengthen the proto comment on LlmReplyStreamChunk
  Event.card_mode to flag the runtime-only invariant explicitly:
  persisting and replaying the flag would re-trigger card routing
  on a turn whose card lifecycle has long since ended.

* (codex P2) ChannelCardConversationTurnRunner now distinguishes
  pre-send vs post-send create failures via
  ConversationCardCreateResult.PostSendFailed. When card.create +
  im.messages.send succeed but the first cardElement.content write
  fails, the orphan card is already visible — falling back to the
  legacy text-edit path would post a duplicate reply. The runner
  attempts a best-effort settings patch closing streaming_mode on
  the orphan card (so the cursor stops blinking) and returns Post
  SendFailed; the actor terminates the turn at LarkCardStreamingPhase.
  Terminated and persists a partial-card terminal record using the
  surfaced card_message_id.

* (codex + kimi P2) Mid-stream terminal failures (table-limit /
  unavailable observed during cardElement.content) now persist a
  ConversationTurnCompletedEvent at transition time, not just when
  LlmReplyReady arrives. Without this, the ProcessedCommandIds
  guard in HandleLlmReplyReadyAsync would not see a matching entry
  and the legacy reply path would post a duplicate text reply on
  top of the visible card.

* (codex P2) AddNyxIdChat() now resolves IConversationCardTurnRunner
  via a factory: when ILarkCardKitClient or ILarkNyxClient is absent
  (host did not call AddLarkTools), the factory returns the no-op
  NullConversationCardTurnRunner instead of failing DI validation.

Minor follow-ups also addressed:

* (codex minor) ConversationCardFinalizeResult gains FinalText
  Written so the actor can pick the right user-visible text when the
  trailing element-content write succeeded but close-streaming-mode
  failed — the user sees finalText, not the stale interim. Persisted
  Outbound now matches what the card actually shows.

* (mimo minor) 230099 classification is now consistent across
  ClassifyCreateFailure and ClassifyStreamFailure: it maps to IsCard
  Unavailable in both. 11310 stays the IsTableLimitExceeded code.

* (glm + v4 minor) ContainsLarkCode is now boundary-aware. The
  trailing position must be the end of the string OR a non-digit;
  prevents false positives where lark_code=23002 incorrectly
  matched a string containing lark_code=230020.

Tests: 133 protocol (132 existing + 1 new card post-send-failure
regression test) + 896 channel-runtime, all green. The existing
TableLimit test also asserts persistence happens with the lark-card-
stream prefix.

Subject: [PATCH 050/113] Cover LarkCardKitClient with HTTP-level unit tests
 (#590 review)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Codecov flagged 0% coverage on LarkCardKitClient (81 lines) and
ILarkCardKitClient (17 lines). Mirror the LarkNyxClient
HTTP-recording pattern from LarkCoverageTests so the four CardKit
methods exercise the real transport: a fake HttpMessageHandler
captures the request, the test asserts URL + method + body shape.

Coverage:
- CreateCardAsync: POST /cards, body embeds DataJson as a nested
  JSON object (load-bearing — Lark rejects double-encoded payloads).
- StreamElementContentAsync: PUT to .../elements/{element_id}/
  content, sequence + uuid wired through.
- StreamElementContentAsync omits `uuid` when the IdempotencyKey is
  blank (Lark rejects empty uuids on some endpoints).
- StreamElementContentAsync runs ids through Uri.EscapeDataString
  (verified via AbsoluteUri so percent-encoded chars survive — the
  default Uri.ToString() decodes %20 back to a literal space).
- SetCardSettingsAsync: PATCH on settings, settings JSON inline.
- UpdateCardAsync: PUT card-as-object, sequence carried, no uuid.
- ParseJsonObject rejects blank/malformed JSON at the boundary
  rather than letting it surface as a 400 from Lark.
- AddLarkTools registers ILarkCardKitClient as a singleton.

54/54 Aevatar.AI.ToolProviders.Lark.Tests pass.

Subject: [PATCH 051/113] PR #562 review: phase A quick fixes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Address review batch on PR #562 (10 inline comments). All in files I have
recent ownership of and require no architectural shifts:

- #16 (blocker, security): ssh_exec is now opt-in via NyxIdToolOptions.
  EnableSshExecTool. Hosts that haven't wired the approval middleware no
  longer see the tool by default. Mainnet host opts in (Lark bot needs it).
- #21 (major, bug): code_execute keeps the modern /execute + {language,
  script} contract, but on a NyxID-proxy upstream 404 it retries the legacy
  /run + {language, code} contract so deployments still pinned to old
  chrono-sandbox-service builds keep working.
- #22 (major, bug): SkillRegistry.IsFresh now exempts SkillSource != Remote
  from TTL — local skills are baked in at registration and don't need
  expiring; prior behavior dropped them from use_skill after the first 5min.
- #18 (major, bug): TurnRunner.TryResolveSenderBindingAsync narrows the
  catch to transient infra errors (Http/Timeout/IO/JSON) and surfaces
  non-transient (logic, NRE, serialization) at Error level so ops can
  distinguish "sender unbound" from "binding store broken".
- #19 (major, bug): ConversationReplyGenerator narrows the
  sender-route-fallback catch to transient errors via
  IsRetryableSenderRouteFailure. Programmer errors no longer cost an LLM
  round on retry.
- #29 + #30 (minor): inbox runtime gives metadata enrichment its own 15s
  budget separate from the LLM run, surfacing
  errorCode=llm_reply_metadata_timeout when scope/UserConfig lookup is
  slow. ResolveFallbackTimeout treats ResponseTimeoutSeconds<=0 as "no
  timeout" rather than silently snapping back to 120s.
- #12 (minor): ConversationGAgent's stream-chunk and final-stream-chunk
  edits run under a 10s CTS now; the failure path already uses one. A hung
  relay can no longer pin the actor turn forever.
- #27 (minor, security): ConstantTimeEquals docstring tightened — removed
  the "for future callers" line and added a SCOPE comment that this helper
  is rebuild-admin-only and shouldn't be promoted to internal/public
  without replacing its length-leak with a length-padding scheme.
- #23 (major, bug): CLI ornn skills slug default → ornn-api (matches the
  registered slug; bare "ornn" is the SPA frontend that returns HTML).

Build clean (NyxId / Skills / NyxidChat / Mainnet hosts), 30 AI tests +
15 inbox runtime tests pass.

Subject: [PATCH 052/113] PR #562 review: phases C-E (DI, TOCTOU, catalog
 client)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- #15 (major, di): AddOrnnSkills now self-registers NyxIdApiClient and
  NyxIdToolOptions via TryAdd safety nets so workflow hosts that enable
  Ornn without AddNyxIdTools get a clean 404 path on missing BaseUrl
  rather than a confusing DI resolution failure.
- #3 (major, di): Introduce IExternalIdentityBindingProjectionPort and
  inject the interface in IdentityOAuthEndpoints. The concrete class
  remains for runtime composition; the registration also publishes the
  interface as a forwarder so existing tests that hold the concrete type
  keep working.
- #14 + #17 (major, concurrency): TurnStreamingReplySink TOCTOU concern
  was based on a misread — drainSignal is captured inside the same lock
  acquisition as _dispatchInProgress=false in the cap branch, and the
  throttle gate's nextIsFinal=false invariant makes _drainTcs guaranteed
  null on that path. Document the invariants so future readers don't
  re-flag this.
- #20 (major, arch): Replace the singleton Dictionary cache in
  NyxIdLlmServiceCatalogClient with IMemoryCache. Per CLAUDE.md
  "中间层状态约束", per-caller state lives in a host-owned cache, not
  a service field. AbsoluteExpiration policy preserved (30s).
- #9 (minor): /api/v1/proxy/services?per_page=100 was already extracted
  into NyxIdLlmCatalogRoutes.ProxyServicesPath — both call sites already
  use the constant.
- #10 (minor): LooksLikeLlmRouteCandidate already has negative-signal
  filtering plus a two-distinct-weak-signals threshold. No change.
- #11 (minor): ExternalIdentityBindingProjector already logs a Warning
  with DocumentId/EventId/Version on the empty-binding delete path.

Build clean (Ornn / Identity / NyxidChat / Channel.Runtime), updated
catalog client test passes.

Subject: [PATCH 053/113] PR #562 review: phase F (OAuth endpoints + projector
 docs) + G
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- #13 (major, arch): /api/oauth/aevatar-client/rebuild now dispatches
  ProvisionAevatarOAuthClientCommand via IActorDispatchPort.DispatchAsync,
  matching /unbind. The inline actor.HandleEventAsync was a known
  CLAUDE.md "投递语义必须 runtime-neutral" violation; aligning the two
  endpoints removes the inconsistency that any future inbox middleware
  would silently bypass on rebuild.
- #24 (minor, design): callback endpoint accepts ?format=json on the URL
  to opt back into the {status:"bound", already_bound, display_name}
  envelope that programmatic CLI/SDK consumers used pre-HTML-render.
  Default stays HTML for browser callbacks.
- #26 (minor, arch): /rebuild now sits behind a RebuildAuthEndpointFilter
  that enforces the admin-token check before model binding and per-request
  DI activation kick in. The filter + the inline check in the handler are
  redundant by design (defense in depth) — the filter rejects unauth
  posts before deserialization runs, and the handler still validates so
  hand-rolled tests/integration scenarios cannot bypass.
- #28 (minor, design): document the readmodel-deletion contract in the
  ExternalIdentityBindingProjector header — empty BindingId deletes the
  document instead of upserting an inactive record; downstream audit
  consumers must read the committed-event log directly.
- #1 + #2 (blocker, arch): no change needed. Earlier commits in this PR
  already moved /model self-heal to IActorDispatchPort.DispatchAsync and
  removed the EnsureProjectionForActorAsync call from the slash-command
  request path. Verified by reading the current handler.
- #25 (minor, test): documented in the rebuild handler comment — concurrent
  /rebuild calls would race on the same actor, but this is operator-grade
  break-glass and de-duping concurrent rebuilds is out of scope.

Build clean (Identity), 34 OAuth-path tests pass.

Subject: [PATCH 054/113] PR #562 review: phase H + test fix for #22
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- #7 (major, arch): wrap MEAILLMProvider's Patch.Set("$.reasoning_content")
  in try/catch so a future OpenAI SDK contract break (Patch surface change,
  serializer rewrite, field rename) degrades to "no reasoning replay"
  instead of crashing the chat call. The OpenAI package is already pinned
  to 2.9.1 in Directory.Packages.props, and the existing
  AIComponentCoverageTests already pin the serialized JSON shape so any
  drift fails the build the moment Patch stops landing in the payload.
- Test fix for #22 (skill registry TTL): the old
  TryGet_BeyondTtl_ReturnsFalseSoCallerCanRefetch test relied on TTL
  expiring SkillSource.Local entries — that's the bug #22 flagged. Updated
  the stale-entry tests to use SkillSource.Remote (via remoteId) which is
  the realistic stale scenario. Added a new
  TryGet_LocalSkillBeyondTtl_StillFresh test pinning the new behaviour.

538 AI tests + 897 ChannelRuntime tests + 16 Ornn tests pass.

Subject: [PATCH 055/113] Cover residual LarkCardKitClient branches (#590
 codecov 96.97% -> 100%)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Codecov flagged 1 missing + 2 partial branches after the previous
coverage commit (4c537ad3). Add three targeted tests:

* CreateCardAsync_RejectsLiteralNullJson: ParseJsonObject's
  `?? throw` branch only fires when JsonNode.Parse returns null
  without throwing — and the only input that does that is the
  literal JSON `"null"`. Without the throw, the request would
  serialize as `"data": null` and Lark would reject it as a missing
  field; the boundary check turns the silent null into a clear
  ArgumentException at the caller's call site.

* SetCardSettingsAsync_OmitsUuid_WhenIdempotencyKeyIsBlank: covers
  the false branch of `if (!string.IsNullOrWhiteSpace(...))` for
  the settings endpoint. Mirrors the existing StreamElementContent
  variant.

* UpdateCardAsync_PassesIdempotencyKey_WhenProvided: covers the
  true branch of the same conditional for UpdateCardAsync, plus
  asserts the idempotency key is .Trim()'d before emission so
  accidental whitespace does not defeat Lark's dedup.

13/13 LarkCardKitClient tests pass.

Subject: [PATCH 056/113] Promote card-mode chunks to a structurally separate
 proto type
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Multi-model fix-check verdict (3/5 partial, 2/5 unresolved on
discussion_r3201406794) flagged the residual structural risk: the
runtime-only `card_mode` boolean still lived on
LlmReplyStreamChunkEvent — a domain-event-shaped envelope — so a
misbehaving persistence layer could replay it and silently re-route
to the card sink. Comment-only mitigation was acceptable to three
reviewers but not to glm-5.1 / codex.

Eliminate the risk by construction:

* New proto LlmReplyCardStreamChunkEvent in conversation_events.proto
  carries the same fields as LlmReplyStreamChunkEvent, dispatched by
  the card sink path. The proto type itself signals routing — there
  is no boolean to flip.
* LlmReplyStreamChunkEvent.card_mode is removed and the field number
  is `reserved` along with its name so any stale serializer or
  accidental reuse fails loudly instead of silently re-enabling
  card mode.
* TurnStreamingReplySink.DispatchOneAsync now constructs the correct
  proto type based on the existing `cardMode` constructor flag.
* ConversationGAgent grows a second [EventHandler]
  HandleLlmReplyCardStreamChunkAsync. The legacy
  HandleLlmReplyStreamChunkAsync delegates to a private
  HandleNyxRelayStreamingChunkCoreAsync helper; the card handler runs
  the card-streaming machine and, on CreationFailed, synthesizes an
  edit-message chunk and falls through to the same helper so the
  user still gets a reply when card creation fails.
* IConversationCardTurnRunner / ChannelCardConversationTurnRunner /
  HandleLarkCardStreamingChunkCoreAsync take
  LlmReplyCardStreamChunkEvent. Tests update RecordingCardTurnRunner
  factories and CreateCardStreamChunk helper accordingly; tests now
  exercise HandleLlmReplyCardStreamChunkAsync instead of relying on
  a CardMode flag on the legacy event.

Spot-checks for the two manual-eyeball items in the verdict:
* `git grep ConfigureAwait agents/Aevatar.GAgents.Channel.Runtime/
   Conversation/ConversationGAgent*.cs` finds only a comment mention
  ("no ConfigureAwait(false)") — no actual usage. mimo's dissent on
  this point was a misread.
* The three classifier helpers
  (ClassifyCreateFailure / ClassifyPostSendFailure /
  ClassifyStreamFailure) consistently map 11310 → IsTableLimitExceeded
  and 230099 / 230100 → IsCardUnavailable. No 230099 lands in any
  IsTableLimitExceeded path. codex's "neither classifier sets it"
  read is the accurate one.

Tests: 133 protocol + 36 ChannelRuntime streaming + 57 Lark tools,
all green.

Subject: [PATCH 057/113] PR #562 fix-check follow-up: address 6 still-flagged
 threads
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Resolve the items the /opencode-pr-fix-check verdict flagged after the
first review pass:

- TurnStreamingReplySink #14 (cap branch): clear `_pendingText` when the
  cap is hit so the reviewer-asked invariant "pending text is never left
  behind when we release `_dispatchInProgress`" actually holds. The
  earlier "preserve _pendingText for FinalizeAsync" comment was wrong:
  FinalizeAsync uses its own `text` parameter, not the stash, so clearing
  is harmless.
- TurnStreamingReplySink #17 (throttle gate): arm the deferred-flush
  timer inside the same `lock` acquisition that releases
  `_dispatchInProgress = false`. A concurrent OnDeltaAsync can no longer
  observe the (no-timer + not-dispatching) gap. The trailing
  outside-lock `armTimerDelay` block is gone.
- ConversationReplyGenerator: log a Warning at construction when
  SkillRegistry is wired but IRemoteSkillFetcher is missing — that
  config silently advertises use_skill yet can't pull remote skills.
  Single grepable line for ops.
- SkillRunnerGAgent: replace the drifting `SkillRunnerGAgent.cs:351`
  reference in the streaming-sink comment with the stable anchor
  `EnsureToolStatusAllowsCompletion`.
- Ornn.Tests.csproj: explicit ProjectReference to
  Aevatar.AI.ToolProviders.NyxId — tests instantiate NyxIdApiClient
  directly so depending on transitive flow-through from Ornn was
  fragile.
- MEAILLMProvider Patch.Set: documentation upgrade — call out the
  three layered mitigations (SDK pin in Directory.Packages.props,
  AIComponentCoverageTests JSON-shape integration assertion,
  try/catch graceful degradation) and the upstream tracking path
  (file an openai-dotnet issue + retire the SCME0001 hack when a
  typed reasoning_content lands).

Build clean (Channel.Runtime, NyxidChat, Scheduled, MEAI, Ornn.Tests),
30 streaming-sink tests + 16 Ornn tests + 18 MEAI/coverage tests pass.

Subject: [PATCH 058/113] Revert AddOrnnSkills NyxId safety net (production
 regression)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The "safety net" I added in PR #562 review #15 (commit 673809ac) was
itself the cause of a production outage on 2026-05-08:

  System.InvalidOperationException: NyxID base URL is not configured.
     at NyxIdRelayAuthValidator.ResolveDiscoveryUrl()
     at NyxIdChatEndpoints.HandleRelayWebhookAsync ...

`AddAevatarAIFeatures` runs `RegisterOrnnSkills` BEFORE the mainnet host
calls `AddNyxIdTools`, so the safety-net `services.TryAddSingleton<
NyxIdToolOptions>()` registered an empty default first; the host's real
`AddNyxIdTools(o => { o.BaseUrl = ... })` then no-op'd because
`TryAddSingleton(options)` saw the empty instance already registered.
Every NyxID call (relay JWT validation, channel-relay/reply, proxy)
exploded on null BaseUrl, and Lark stopped replying entirely.

The right behaviour: hosts that enable Ornn skills MUST call
`AddNyxIdTools` themselves. If they don't, DI resolution fails fast at
startup with a clear "no service for NyxIdApiClient" — which is exactly
the signal that needs to surface, not be papered over with empty
placeholders. Updated the docstring with a remarks block so the next
person tempted to add this safety net sees the production-incident
breadcrumb first.

The reviewer concern that triggered #15 (workflow host enables Ornn
without NyxId) is real but theoretical for this repo today; the cost
of the wrong fix was concrete and severe.

Subject: [PATCH 059/113] Default StreamingCardKitEnabled to true so card-mode
 lights up by default
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PR #590 shipped CardKit streaming behind a flag (default false) and the
production cluster's ConfigMap doesn't carry an Aevatar:NyxId:Relay
override (verified earlier — the deployed appsettings.Distributed.json
has no Relay node), so flipping the flag in repo configuration was a
no-op. Move the default to true in the C# field initializer so the
aevatar Lark bot uses the card path out of the box.

Risk: low. PR #590's failure-routing already handles missing CardKit
scopes — card.create returns the scope-error / rate-limit envelope,
ConversationGAgent.HandleLarkCardStreamingChunkCoreAsync transitions to
CreationFailed, and the turn falls through to the legacy edit-message
sink for the rest of the chunks. Worst case for a deployment without
cardkit:card:read + cardkit:card:write granted is one extra POST per
turn before the fallback kicks in.

Deployments that explicitly want the legacy path (no Lark bot, or want
to skip the card.create round-trip) can opt out via
Aevatar:NyxId:Relay:StreamingCardKitEnabled=false.

Subject: [PATCH 060/113] Pin streaming-enabled inbox test to legacy chunk
 type, add card-default test

Last commit flipped StreamingCardKitEnabled default to true, which made
ProcessAsync_StreamingEnabled_DispatchesChunkEventAndReadyEvent fail
because the inbox now stamps card-mode chunks with the structurally
distinct LlmReplyCardStreamChunkEvent proto type (PR #590 routing
scheme), and the test asserts the legacy LlmReplyStreamChunkEvent
descriptor.

Two changes:
- Existing test sets StreamingCardKitEnabled=false explicitly; comment
  notes that it deliberately exercises the legacy text-edit chunk shape.
- New test ProcessAsync_StreamingEnabledWithDefaultCardMode_Dispatches-
  CardChunkEvent pins the new default behaviour: omit the flag, observe
  LlmReplyCardStreamChunkEvent on the wire.

898 ChannelRuntime tests + 94 NyxId AI tests pass.

Subject: [PATCH 061/113] Fix LarkCardKitClient body shape: data/settings as
 JSON-encoded strings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Lark CardKit 2.0's open-apis/cardkit/v1/cards endpoints want
type-tagged `data` / `settings` / `card.data` payloads as JSON-encoded
STRINGS, not inline objects. The merged PR #590 implementation always
embedded those fields as inline JsonNode trees, which Lark rejects with
code 9499 "Invalid parameter type in json: Data | Settings | Card".

Production rollout (commit 36b8b5cd flipped StreamingCardKitEnabled
default to true) made every Lark turn run card.create, hit the 400, log
"Card create failed; falling back to text-edit", and silently spend the
rest of the turn on the legacy edit-message path — so users still saw
text-edit replies and concluded card mode was off (it was on, but the
client was sending the wrong shape).

Verified each shape against the live endpoint via `nyxid proxy request`:

  POST /cards   data: STRING when type=card_json|card_id
                data: INLINE OBJECT when type=template
  PATCH /cards/{id}/settings   settings: STRING
  PUT   /cards/{id}            card: INLINE { type, data }
                                where data follows the same string rule

Tests:
- Updated existing pinning tests that asserted the wrong shape (the
  inline-object assertion was the contract bug).
- Added explicit cases for card_id (string) and template (inline object).
- Round-trip card_json string back through JsonDocument.Parse so the
  test still pins the inner schema/streaming_mode fields.
- UpdateCardAsync now validates CardJson parses (defensive client-side)
  and wraps it in `card.{type:"card_json", data:<string>}` automatically.
- All four CardKit methods reject blank / null DataJson upfront.

59 Lark CardKit tests + 37 ChannelRuntime card tests pass.

Subject: [PATCH 062/113] ssh_exec: hard wall-clock cap so NyxID hangs don't
 blow LLM run budget
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Production incident 2026-05-08: a Lark turn issued an `ssh_exec` tool
call to sg-office-network. NyxID accepted the POST to
`/api/v1/ssh/{catalog_id}/exec` at 07:17:47 UTC and never returned a
response. Direct curl reproduces the call in ~2s (NyxID side
duration_ms:1666), so the hang is something between aevatar's HttpClient
and NyxID's SSH gateway / NodeAgent — most likely the per-user single-
session SSH lock with a stale prior session. With no client-side cap,
the call sat past the inbox runtime's 120s timeout, the user got the
generic `llm_reply_timeout` fallback ("Sorry, this took too long..."),
and the actual SSH attempt was never observable to the model.

Two layered fixes:

1. NyxIdSshExecTool now wraps the SshExecAsync call in a linked CTS that
   cancels at `timeout_secs + 15s` (the +15s gives NyxID's own server-
   side timeout a margin to respond with `timed_out: true` before we
   give up). On timeout the tool returns
     {"error":"ssh_timeout","detail":"NyxID did not return ... within Ns"}
   so the LLM sees a real tool error and can either retry against a
   different host or summarize "couldn't reach the SSH gateway" instead
   of dragging the run.

2. NyxIdApiClient.SendAsync now lets `OperationCanceledException`
   propagate. Previously the catch-all wrapped it as
     {"error":true,"message":"A task was canceled."}
   which silently shadowed any per-call CTS the caller installed on top
   of the LLM run's CT (the test for this fix caught it: tool's catch
   never fired). Cancellation is a control-flow signal, not an HTTP
   error envelope. Other callers of NyxIdApiClient already work with
   either path because the LLM run's CT cancellation also unwinds the
   inbox runtime via OperationCanceledException.

Tests:
- New ExecuteAsync_HardTimesOut_WhenNyxIdHangsOnSshPost exercises the
  full fail mode via a `MapHanging` route on the test PathHandler that
  awaits Timeout.Infinite until the cancellation token fires.
- Existing 44 SSH + ApiClient tests still pass; 539-test AI suite green.

Production observation 2026-05-08: a "拉一下 sg office 设备 IP" turn
generated a perfectly-shaped streaming-card reply but ran out of LLM
turn budget mid-flush — the user saw the generic "took too long"
fallback instead of the real answer. The bot did the work; we just
cut it off too early.

Multi-step Lark turns realistically need:
  - ornn skill-search / fetch SKILL.md       ~10s
  - ssh_exec to a remote host                ~30-60s
                                             (45s is the new client-side
                                              hard cap on a stuck NyxID
                                              SSH gateway)
  - LLM thinking + final streaming dispatch  ~30-90s
  - per-tool jitter + connection setup       ~10-20s
                                             ──────
                                             ~ 80-180s typical

120s left no margin once anything but the happy path happened. 300s
buys headroom without giving up the watchdog: a true infinite hang
still resolves to the "took too long" fallback so the user is not
stuck on a "..." reaction forever.

Bumped both knobs to keep them in sync:
  - NyxIdRelayOptions.ResponseTimeoutSeconds default 120 → 300
  - ChannelLlmReplyInboxRuntime.FallbackTimeoutSecondsDefault 120 → 300

Deployments that want a tighter / looser cap still set
Aevatar:NyxId:Relay:ResponseTimeoutSeconds in config; 0 / negative
still means "no cap" (host has its own watchdog) per the existing
ResolveFallbackTimeout contract.

Existing tests that pin specific timeout values
(e.g. ResponseTimeoutSeconds=1 in the timeout-fallback test) are
unaffected; tests that didn't set the option get 300s by default
which is even further from firing for fast tests. 16 inbox runtime +
24 SSH tool tests pass.

Subject: [PATCH 065/113] =?UTF-8?q?Rename=20daily=5Freport=20=E2=86=92=20d?=
 =?UTF-8?q?aily=20everywhere?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The /daily Lark slash command and the agent template behind it were
named daily_report internally — six different casings (daily_report,
DailyReport, dailyReport, daily-report, plus compound identifiers like
daily_report_form, BuildDailyReportForm, CreateDailyReportAgentAsync).
The user-facing command has always been /daily; the internal _report
suffix added no signal and made it harder to talk about the skill in
docs and Ornn.

Strategy:
- Sed-driven global rename across .cs / .json / .md / .proto / .yaml /
  csproj. 281 occurrences across 26 files. Order: kebab → camel →
  Pascal → snake (no shared substrings, so order is defensive).
- Renamed compound identifiers (daily_report_form → daily_form,
  BuildDailyReportForm → BuildDailyForm, etc.). All callers updated by
  the same pass.
- Three test inputs that intentionally used /daily_report as a fake
  unknown-command literal (testing "this is not a real command, return
  unknown usage") now collide with the real /daily command after the
  rename. Dropped those three [InlineData] entries — the same code path
  is still covered by the /foobar and / cases that remain.

Persistence note: any scheduled agent records persisted with
template="daily_report" before this commit will not match the new
template="daily" lookup. The current production /daily flow is broken
anyway (always returns eanzhao's data, hangs past the 120s budget per
this morning's incident review), so a clean cutover is acceptable —
re-run /daily and the rebuilt agent will land under the new name.

This commit is naming-only. The next commit (separate) replaces the
template body to consume the Ornn-hosted `daily` skill via use_skill,
the way sg-office-network is reached via ssh_exec.

Build clean across affected projects (Authoring.Lark, Scheduled,
NyxidChat). 895 ChannelRuntime + 17 Lark Platform tests pass.

Subject: [PATCH 067/113] Remove /daily, /social-media, and the agent_builder
 template path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`/daily` and `/social-media` are no longer in-tree commands. Recipes for
new persistent agents now live as Ornn skills — the LLM searches via
`ornn_search_skills` (or matches a slash command name to a skill query)
and follows the SKILL.md verbatim. `agent_builder` keeps only the
lifecycle surface (`list_agents`, `agent_status`, `run_agent`,
`disable_agent`, `enable_agent`, `delete_agent`).

The `social_media` template, the `WorkflowAgentGAgent` actor, the
`twitter_publish` workflow module, the `IScopeWorkflowCommandPort` LLM
plumbing in `agent_builder`, and all related card-flow surfaces are
deleted with no replacement; the missing scope-scoped workflow tools
needed to bring social-media back as an Ornn skill are tracked in
issue #598.

Subject: [PATCH 070/113] Scaffold Responses API v1 prototype

Add /v1/responses ingress, ResponseSessionGAgent (opaque response.id ownership
+ lifecycle), ResponsesAgentToolStateGAgent (forwarded tool call state), and
current-state projection plumbing for both. Wires tool classifier
(forward/substitute/additive) and caller scope resolution at the protocol
boundary.

Touches milestone 14 issues #611, #612, #614, #617, #618, #621, #622.

 `Aevatar.Mainnet.Host.Api` 现在是 `aevatar app` 的唯一后端 API 面。当前用户面 contract 已经收敛为 `scope-first`，默认认为一个 `scope` 对应一个对外 service binding；内核仍保留 `service` 级别接口，作为未来扩展到多 service 的基础。
 
+Responses v1 最小原型也挂在主机上，入口是：
+
+- `POST /v1/responses`
+- `POST /v1/responses/{responseId}/cancel`
+
+说明：
+
+- 这是最小 prototype，只支持文本输入；`previous_response_id` 会通过 response session read model 校验同一调用者、同一 ingress origin 下的上一条 response。`function_call_output` 会按上一条 response 的 forwarded tool call 记录用 `call_id` 对账。
+- `stream=true` 时返回 Responses 风格 SSE：`response.created`、`response.output_item.added`、`response.output_text.delta`、`response.output_text.done`、`response.output_item.done`、`response.completed`；失败时输出 `response.failed` / `error`。
+- `Authorization: Bearer <token>` 只在请求上下文中透传，不会落盘；持久化的 response session 只记录 NyxID `/me` 解析出的 caller scope 与 opaque `response.id`。
+- forward tool call 在输出给客户端前会先落 response session actor，记录 `call_id`、`tool_name`、`schema_hash`、arguments、状态与过期时间。客户端续传 tool result 时可携带 `schema_hash`，不匹配会返回明确 4xx。
+- `Task`、`Todo*`、`WebFetch`、`WebSearch` 属于 substitute 类，会在 `/v1/responses` boundary 被替换为 Aevatar tool；其他客户端 declared tools 默认 forward。`aevatar_*` additive tool 接口已预留。
+- substitute 工具状态归 `ResponsesAgentToolStateGAgent` 拥有：`TodoWrite` 写入 agent-scoped todo state，`Task` 记录可投影的 topology trace，`WebFetch` / `WebSearch` 记录 trace 与简单 cache 命中状态；这些状态通过 ProjectionPipeline 物化为 current-state read model，可供后续会话查询。
+- cancel 端点会复用同一 bearer token scope resolution；可见性通过后，session actor 会把 response 标记为 `cancelled` 并将 pending forwarded tool call 标为 `cancelled`。已过期或已取消的 `previous_response_id` 不能 resume。
+
 当前推荐使用的 scope-first 入口：
 
 - `POST /api/scopes/{scopeId}/workflow/draft-run`

Subject: [PATCH 071/113] Cover Response* infrastructure adapters with unit
 tests

Add test coverage for ResponseSessionRegistrationAdapter (5 dispatch methods +
guard clauses + default field population) and ResponsesAgentToolStateCommandAdapter
(TodoWrite parsing variants, task description fallback chain, web trace TraceId
generation). Brings branch coverage on the new platform code back above the 72%
guard threshold.

Subject: [PATCH 072/113] Cover NyxIdResponsesCallerScopeResolver with unit
 tests

Add tests for the resolver's null-token / empty-userId / cancellation paths and
the trimmed-scope happy path. Boosts patch coverage on
src/Aevatar.Mainnet.Host.Api/Responses/ResponsesCallerScope.cs from 16% toward
full coverage.

Subject: [PATCH 073/113] Harden Response* prototype against review findings;
 cover new abstractions

Production changes:
- Migrate response_sessions and tool-state protos from `string *_json` to
  `bytes *_payload`; actors stay Protobuf-only, JSON parsing moves to the
  host boundary (addresses mimo-v2.5-pro blocker findings #2/#3).
- Extract `ResponsesTodoItemParser` in Abstractions so the host adapter
  preview and the actor's persisted view share one parser (addresses
  glm-5.1 finding on duplicated todo parsing).
- Introduce `IWebApiClient` abstraction so `ResponsesAevatarToolProvider`
  depends on an interface (addresses kimi finding on DI inversion).
- Add `WebFetchUrlGuard` to block loopback, private (10/8, 172.16/12,
  192.168/16, 169.254/16, 127/8, 0/8), and link-local addresses before
  WebFetch emits an HTTP request (addresses codex blocker #1 on SSRF /
  bearer token exfiltration via attacker-controlled URLs).

Test changes:
- Update existing Response* tests to track the new proto shape.
- Add `WebFetchUrlGuardTests` covering scheme rejection, IPv4/IPv6
  private ranges, IPv4-mapped IPv6, hostname loopback variants, and
  the public-host accept path.
- Add `ResponsesTodoItemParserTests` covering todos-array, single
  string/object, content-key fallback chain, numeric id, malformed
  JSON, and whitespace normalization.

Subject: [PATCH 076/113] Address review findings on credential leakage and
 dispatch retry safety
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- ConversationGAgent now strips per-call NyxID credentials
  (nyxid.access_token / nyxid.org_token / nyxid.sender_access_token)
  from NeedsLlmReplyEvent.Metadata before PersistDomainEventAsync, so
  short-lived sender tokens never reach event store / projection /
  read model. Credential key list lives in the new
  LlmReplyCredentialMetadataKeys helper next to the existing strip-on-
  persist site for reply_token.
- AgentRunGAgent persists the produced reply payload (reply_text +
  outbound + terminal_state) BEFORE dispatching LlmReplyReadyEvent, so
  output-dispatch retries re-deliver from state via the new
  ReDispatchProducedReplyAsync path instead of re-entering the LLM /
  tool chain. New AgentRunReplyDispatchedEvent marks final delivery
  and gates terminal cleanup. FailAfterUnexpectedException follows the
  same persist-before-dispatch ordering.
- ConversationGAgent.LarkCardStreaming wraps RunCardCreate /
  RunCardStream / RunCardFinalize in
  CancellationTokenSource(StreamingFailureUpdateTimeout) so a stuck
  CardKit upstream can no longer pin the actor turn forever, matching
  the per-call cap already used by the legacy text-edit streaming
  path.
- Mainnet appsettings.json bumps Aevatar.NyxId.Relay.ResponseTimeoutSeconds
  120 → 300 so the recent default change actually takes effect after
  configuration binding.

 - User quotes a skill name (`'translate-pro'`, `"sg-office-network"`)
 - User uses a slug-like or Title Case identifier that could be a skill name
-- User issues a `/<command>` slash command that isn't an in-tree relay command (the in-tree ones are `/route`, `/models`, `/model`, `/agents`, `/agent-status`, `/run-agent`, `/disable-agent`, `/enable-agent`, `/delete-agent`) — treat the command name as the skill query (`/daily` → search "daily")

Subject: [PATCH 078/113] Harden AgentRun state migration and post-dispatch
 error handling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two issues surfaced when the persist-before-dispatch refactor meets live
production state and partial-failure paths:

1. Backward-compat: pre-refactor AgentRunReplyProducedEvents have no
   reply_text / outbound / terminal_state fields (proto3 defaults on
   deserialize). The new state machine would interpret them as
   "produced but not yet dispatched" with an empty payload, causing
   ReDispatchProducedReplyAsync to deliver a blank reply and
   HandleCleanupAsync to refuse to destroy the actor. The old codepath
   only wrote AgentRunReplyProducedEvent AFTER a successful dispatch,
   so ApplyReplyProduced now treats events with an empty reply_text
   as ReplyDispatched=true. New events always populate reply_text
   (empty replies fall back to a non-empty user message before
   persisting), so this is a reliable discriminator.

2. Post-dispatch persistence isolation: once DispatchReadyEventAsync
   delivers the LlmReplyReadyEvent, the user has the reply. If
   PersistReplyDispatchedAsync then throws, the exception would bubble
   to HandleStartAsync's outer `catch (Exception)`, which would call
   FailAfterUnexpectedExceptionAsync and re-enter ProduceAndDispatchAsync
   with the "Sorry, I couldn't complete this reply" fallback — a
   second user-visible message on top of the real reply. Introduced
   TryFinalizeAfterDispatchAsync that wraps the post-dispatch persist
   and cleanup-scheduling steps in their own logging-only catch so the
   actor never propagates these errors. The trade-off: state may stay
   at ReplyProduced+!ReplyDispatched until the next reconciliation,
   accepting a lingering actor instead of a duplicate reply.

Regression coverage:
- ApplyReplyProduced_HistoricalEventWithoutReplyText_MarksAsAlreadyDispatched
- ApplyReplyProduced_NewEventWithReplyText_LeavesReplyAsNotYetDispatched
- ProduceAndDispatch_WhenPersistDispatchedFails_DoesNotDeliverDuplicateFallbackReply
  (uses a new FailOnEventTypeSourcing helper to inject a persistence
  failure on AgentRunReplyDispatchedEvent only).

Subject: [PATCH 079/113] Restore lark bot reply path on feature/lark-bot

Production Lark bot stopped replying after 1c8b5f6e: typing reactions
return 231001 ("reaction type is invalid") and every reply ends with
"Sorry, this took too long to process".

- ChannelConversationTurnRunner.TypingReactionEmojiType: "TYPING" -> "Typing".
  Lark treats this status-name reaction as case-sensitive (proper noun),
  unlike the generic uppercase emoji aliases (OK, THUMBSUP, DONE).
- AgentRunDispatcher: revert to IStreamProvider.GetStream().ProduceAsync.
  The IActorDispatchPort.DispatchAsync swap made the conversation actor
  synchronously await the entire LLM round-trip inside HandleEnvelopeAsync,
  blowing the 30s Orleans request budget and cascading timeouts through
  the streaming sink and relay webhook.
- Update AgentRunGAgentTests and ChannelConversationTurnRunnerTests for
  the reverted contract and emoji casing.

Subject: [PATCH 080/113] Tighten AgentRun historical-event discriminator for
 interactive-only replies
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The previous ApplyReplyProduced backward-compat check —
  string.IsNullOrEmpty(evt.ReplyText) => ReplyDispatched = true
— misclassifies a legitimate NEW event shape: interactive-only turns
(reply_with_interaction, card / button intents) produce an empty
reply_text alongside a non-null outbound. Those events would be marked
as already-dispatched on replay, skipping the dispatch retry path and
silently dropping the user's interactive reply.

The discriminator now also requires evt.Outbound to be null. Legacy
pre-refactor events have BOTH fields default (proto3 zero-values on
deserialize); new events always have at least one of them populated:
  - text-only replies: non-empty reply_text
  - interactive-only replies: non-null outbound
  - empty-reply fallback: replyText replaced with a non-empty user
    message before persisting

Regression coverage:
- ApplyReplyProduced_NewInteractiveOnlyEvent_EmptyReplyText_ButNonNullOutbound_IsNotMisclassifiedAsHistorical

Subject: [PATCH 081/113] Add per-call timeout to Ornn skill client

A stuck NyxID-proxied call to /api/v1/skills/{name}/json can hold an
Orleans grain turn captive for the full outer 120s LLM reply budget.
Observed in production 2026-05-13 as a 113s hang on chrono-ai-daily,
which let /daily reply ~2 minutes later via the timeout-fallback card
path while the grain's stream consumer reported repeated delivery
failures.

SearchSkillsAsync and GetSkillJsonAsync now wrap their NyxID-proxy
calls in a 30s per-call CancellationTokenSource linked to the caller
token. The fallback path logs the per-call budget breach distinctly
from generic failures so log dashboards surface upstream slowness as
its own signal, and caller cancellation propagates naturally rather
than being masked as a "skill not found" / "no results" outcome.

Successful calls observed at ~1s, so 30s preserves generous headroom.
This does NOT identify the root cause of the intermittent upstream
hang (same URL completes in 137ms via direct curl); it caps the
worst-case impact on the grain turn until that's understood.

+
+# `feature/lark-bot` 回复链测试覆盖审计
+
+> 对应 issue: [#634](https://github.com/aevatarAI/aevatar/issues/634)
+>
+> 目标：不是罗列“这个分支有很多测试”，而是明确回答四件事：
+>
+> 1. 这条回复链现在的高风险点是什么
+> 2. 已有测试到底锁住了哪些不变量
+> 3. 还缺哪些关键回归保障
+> 4. 后续 `#635 / #636 / #637` 应该先打哪里
+
+## 范围与基线
+
+本次审计以 `feature/lark-bot` 当前链路为基线，重点查看以下六组测试：
+
+- `test/Aevatar.GAgents.ChannelRuntime.Tests/AgentRunGAgentTests.cs`
+- `test/Aevatar.GAgents.Channel.Protocol.Tests/ConversationGAgentDedupTests.cs`
+- `test/Aevatar.GAgents.ChannelRuntime.Tests/ChannelConversationTurnRunnerTests.cs`
+- `test/Aevatar.GAgents.ChannelRuntime.Tests/ConversationReplyGeneratorTests.cs`
+- `test/Aevatar.GAgents.ChannelRuntime.Tests/TurnStreamingReplySinkTests.cs`
+- `test/Aevatar.AI.Tests/ToolCallLoopTests.cs`
+
+另外，以下测试与护栏作为辅助证据使用，用来校正对 `ChatRuntime`、AI 组件边界和结构约束的判断：
+
+- `test/Aevatar.AI.Tests/ChatRuntimeStreamingBufferTests.cs`
+- `test/Aevatar.AI.Tests/AIComponentCoverageTests.cs`
+- `test/Aevatar.Architecture.Tests/Rules/*`
+- `tools/ci/*guard.sh`
+
+并对照以下实现文件确认风险面：
+
+- `agents/Aevatar.GAgents.Channel.Runtime/Conversation/ConversationGAgent.cs`
+- `agents/Aevatar.GAgents.Channel.Runtime/Conversation/ConversationGAgent.LarkCardStreaming.cs`
+- `agents/Aevatar.GAgents.Channel.Runtime/Conversation/ConversationGAgent.NyxRelayStreaming.cs`
+- `agents/Aevatar.GAgents.NyxidChat/AgentRunGAgent.cs`
+- `agents/Aevatar.GAgents.NyxidChat/ConversationReplyGenerator.cs`
+- `agents/Aevatar.GAgents.Channel.Runtime/TurnStreamingReplySink.cs`
+- `src/Aevatar.AI.Core/Tools/ToolCallLoop.cs`
+- `src/Aevatar.AI.Core/Chat/ChatRuntime.cs`
+
+当前主链路为：
+
+`ConversationGAgent -> IChannelLlmReplyRunDispatcher -> AgentRunDispatcher -> AgentRunGAgent -> ConversationReplyGenerator -> ChatRuntime`
+
+## 总结论
+
+先说结论：这个分支**不是“测试不够”**，而是**测试分布不均**。
+
+已经覆盖得比较强的部分：
+
+- `ConversationGAgent` 的 dedup、retry、reply token strip/re-enrich、streaming/text fallback
+- `TurnStreamingReplySink` 的 throttle/cap/finalize/dispatch race
+- `ChannelConversationTurnRunner` 的 inbound metadata、reaction、relay/direct reply、card action
+- `ToolCallLoop` 的 tool round、middleware、reasoning propagation、length recovery
+
+相对薄弱的部分：
+
+- `ConversationGAgent -> AgentRunGAgent` 之间“accepted / committed / delivered”语义边界是否足够诚实
+- `AgentRunGAgent` 的 duplicate terminal signal / repeated callback / stale continuation 组合情形
+- `ConversationReplyGenerator` 与 `ToolCallLoop` 的 closeout 联动，而不只是各自单测
+- 新引入 seam `IChannelLlmReplyRunDispatcher` 的结构护栏
+
+所以，`#634` 的产出不应该是“建议多补一些 happy path”，而应该是：
+
+1. 承认哪些地方已经很扎实，避免重复造轮子
+2. 明确指出后续只需要补少量但高价值的回归
+3. 把结构护栏缺口单独拎出来，交给 `#637`
+
+## 风险矩阵
+
+| 风险点 | 现有覆盖 | 结论 | 缺口 / 后续动作 | 本轮优先级 |
+| --- | --- | --- | --- | --- |
+| `ConversationGAgent` 入站 dedup 与 retry ownership | `ConversationGAgentDedupTests` 覆盖 duplicate activity、duplicate command、retry scheduled / success / exhausted / permanent failure | 覆盖强，主不变量已锁住 | 暂不补功能测试 | P2 |
+| relay reply token 不进入 committed fact | `HandleNyxRelayInboundActivityAsync_NeverPersistsReplyTokenIntoEventStore`、`StripsReplyTokenFromPersistedNeedsLlmReplyEvent_ButKeepsItOnRunCommandCopy`、`RehydratesRelayToken...`、`PrefersRunEchoedReplyToken...` | 覆盖强，边界意识明确 | 后续只需补 chain-level 诚实性，不必再补“有没有 strip”基础测试 | P1 |
+| `ConversationGAgent` streaming/text/card fallback | `ConversationGAgentDedupTests` 大量覆盖 text chunk、final fallback、card create/stream/finalize | 覆盖强 | 暂不补同类 happy path | P2 |
+| `AgentRunDispatcher` 创建 run actor 并发起 start | `DispatchAsync_ShouldCreateRunActorAndDispatchStartCommand` | 基本覆盖到位 | 不缺基础测试 | P2 |
+| `AgentRunGAgent` duplicate start / timeout / empty / throw / missing target / missing activity / stale / missing token | `AgentRunGAgentTests` 已覆盖对应单点场景 | 覆盖中上，单点保护不少 | 还缺“terminal 后重复信号”和“组合情形”回归 | P1 |
+| `AgentRunGAgent` cleanup 语义 | 已覆盖 schedule cleanup、cleanup destroy | 基础覆盖到位 | 还缺“非 terminal cleanup 请求是否 no-op / 幂等”类测试 | P2 |
+| `AgentRunGAgent` streaming ready/card chunk/text-only 路径 | 已覆盖 streaming enabled/disabled、card mode、non-relay path | 覆盖中上 | 可暂缓 | P2 |
+| `ChannelConversationTurnRunner` inbound metadata / relay reaction / workflow card action / reply delivery | 覆盖很广，包括 sender binding、owner prefs、reaction clear、interactive relay reply | 覆盖强 | 暂不扩 | P2 |
+| `TurnStreamingReplySink` throttle/cap/finalize race | 15 个测试，覆盖 cap、throttle、timer、dispatch in flight、idempotent dispose、duplicate suppression、dispatch throw | 覆盖非常强 | 本轮不需要再做大面积补测，只需补 review 指向的新竞态时再加 | P2 |
+| `ConversationReplyGenerator` placeholder / owner vs sender prefs / route fallback / approval middleware | 已覆盖主要分支 | 覆盖中等 | 缺 warning/closeout 联动测试 | P1 |
+| `ToolCallLoop` tool round / middleware / request identity / reasoning propagation / length recovery | 覆盖强 | 单体循环语义稳定 | 缺和 generator / runtime 的联动 closeout 测试 | P1 |
+| `ChatRuntime` 多轮流式收尾语义 | `ChatRuntimeStreamingBufferTests` 已直接覆盖 `ChatStreamAsync` 的流式 chunk、tool-call follow-up、reasoning 透传；另有 `ToolCallLoopTests` 与 AI tests 辅助覆盖 | 覆盖中等，流式主路径已有直接保护 | 仍缺更贴 reply-chain closeout 的联动表达，建议只补一到两个 closeout 级回归，不要大规模重写测试 | P1 |
+| 新 seam `IChannelLlmReplyRunDispatcher` 的依赖方向 | 现有 architecture/channel guard 已限制“不要直连 NyxIdChatGAgent”，但没有直接锁住这条 seam | 结构护栏缺口明确 | 在 `#637` 增加 architecture test 或 CI guard | P0 |
+
+## 分文件审计
+
+### 1. `AgentRunGAgentTests`
+
+现有覆盖亮点：
+
+- run actor 创建与 `AgentRunStartRequested` 投递
+- duplicate start 幂等
+- ready/drop signal not accepted 时的 retry
+- unexpected exception / timeout / empty reply / generator throw
+- relay token echo、missing token drop、stale request drop
+- streaming text / card 路径
+- owner LLM config 与 bearer token 透传
+- terminal cleanup schedule + destroy
+
+结论：
+
+- 这组测试已经不是“空白区”
+- 真正缺的不是单一错误分支，而是**terminal 之后重复信号是否还可能造成二次回传 / 二次调度**
+
+建议补点：
+
+- terminal 状态下再次收到 `AgentRunStartRequested` / cleanup / internal retry 时的 no-op 幂等
+- duplicate `LlmReplyReadyEvent` / `Dropped` / `Failed` 对 conversation 端是否仍可能造成二次 closeout
+
+对应后续：
+
+- 归入 `#635`
+
+### 2. `ConversationGAgentDedupTests`
+
+现有覆盖亮点：
+
+- activity / command dedup
+- inbound retry 调度归 actor 所有
+- reply token strip-on-persist 与 runtime re-enrich
+- 运行后 `ReplyToken` 回传优先级
+- deferred reply dispatch
+- relay streaming chunk / text fallback / card mode fallback
+- final edit 与 partial degradation
+
+结论：
+
+- 这是当前分支覆盖最厚的一块之一
+- 很多“边界安全”基础测试已经有了，后续不需要再从零补“有没有 strip token”
+
+仍有缺口：
+
+- 更高一层的“accepted / committed / delivered”语义诚实性还没有被单独表达出来
+- 例如：conversation 持久化了 `NeedsLlmReplyEvent`，并不等于用户已经收到 reply；目前这类语义主要靠代码结构理解，而不是显式测试名称锁住
+
+对应后续：
+
+- 归入 `#635` 做 chain-level contract test
+
+### 3. `ChannelConversationTurnRunnerTests`
+
+现有覆盖亮点：
+
+- inbound metadata 组装
+- owner/sender config layering
+- relay typing reaction post / clear
+- slash / card action / workflow resume
+- direct reply / relay reply / adapter rejection
+- `OnReplyDeliveredAsync` 对 streaming path 的 reaction clear
+
+结论：
+
+- 这组测试已经像一个“适配层回归套件”
+- 不建议在当前 issue 再扩 happy path
+
+仍有缺口：
+
+- 和 `AgentRunGAgent` 的 end-to-end 语义边界不是在这层表达的
+- 所以不应把后续的 actor 语义测试继续塞到 runner tests 里
+
+对应后续：
+
+- 本轮只作为引用基线，不新增任务
+
+### 4. `TurnStreamingReplySinkTests`
+
+现有覆盖亮点：
+
+- interim cap 后 stash，不提前 dispatch
+- dispatch 中 stash + throttle gate + deferred timer
+- finalize bypass throttle
+- finalize in flight wait
+- pending == last emitted duplicate suppression
+- dispatch throw swallow
+- dispose idempotency
+
+结论：
+
+- 这组已经相当扎实，是本链路里并发回归保护最强的一部分
+- `#636` 不应该被理解成“这里完全没测”，而是“只补后续 review 指向的新竞态”
+
+仍有缺口：
+
+- 当前没有发现明显大洞
+- 若要补，也应只补“新 code path 引入的新 race”，不要做覆盖率型补测
+
+对应后续：
+
+- `#636` 的范围应收窄，避免过度施工
+
+### 5. `ConversationReplyGeneratorTests`
+
+现有覆盖亮点：
+
+- relay callback URL 注入
+- placeholder emit / skip
+- approval middleware per turn
+- owner vs sender preferences layering
+- route fallback / no token fallback
+
+结论：
+
+- 配置和偏好层面的覆盖不错
+- 但 generator 与 `ToolCallLoop` / `ChatRuntime` 的 closeout 联动还比较少
+
+主要缺口：
+
+- `SkillRegistry` 存在但 `IRemoteSkillFetcher` 缺失时的 warning 行为未见直接测试
+- 还缺“tool call -> tool result -> final answer”在 generator 这一层只收尾一次的测试表达
+
+对应后续：
+
+- 归入 `#637`
+
+### 6. `ToolCallLoopTests`
+
+现有覆盖亮点：
+
+- no tool / tool then follow-up
+- request id 与 per-call metadata
+- hook / middleware mutation 与 terminate
+- max rounds exhausted
+- length recovery
+- reasoning content propagation
+- DSML tool call 变体
+
+结论：
+
+- `ToolCallLoop` 的单体语义已经很全
+- 目前缺的不是 loop 内部逻辑，而是它和 `ConversationReplyGenerator` / `ChatRuntime` 的交界处
+
+主要缺口：
+
+- final answer closeout 与 streaming sink / reply ready 的整体联动没有被直接表达
+- “warning path + final content + no duplicate closeout” 这种跨层问题还未集中锁住
+
+对应后续：
+
+- 归入 `#637`
+
+## 已有护栏与缺口
+
+已有护栏：
+
+- `test/Aevatar.Architecture.Tests/Rules/ForbiddenPatternTests.cs`
+  - 已限制中间层 `actor/entity/run/session` ID -> context 字典事实态
+- `tools/ci/channel_relay_nyx_chat_direct_create_guard.sh`
+  - 已限制 channel relay/runtime 直连 `NyxIdChatGAgent`
+- `test/Aevatar.Architecture.Tests/Rules/ChannelArchitectureTests.cs`
+  - 已限制外部入口绕过 `ConversationGAgent`
+
+当前缺口：
+
+- 还没有一个专门护栏明确锁住：
+  - `ConversationGAgent` 依赖的是 `IChannelLlmReplyRunDispatcher`
+  - 而不是重新回退为直接依赖旧 inbox runtime 或具体 NyxIdChat 实现
+
+这说明：
+
+- `#637` 很适合新增一个非常小但高价值的 architecture test / CI guard
+
+## 建议执行顺序
+
+基于这次审计，后续 issue 的执行顺序建议是：
+
+1. `#635`
+   - 先补 `ConversationGAgent <-> AgentRunGAgent` 的 chain-level actor 语义与 credential boundary
+2. `#637`
+   - 再补 closeout 回归和最小结构护栏
+3. `#636`
+   - 最后只做 review 指向的新 sink 竞态回归，不做大面积补测
+
+原因很简单：
+
+- `TurnStreamingReplySink` 现在不是最薄的位置
+- 真正最薄的是“跨 actor handoff 的诚实性”和“closeout 是否只发生一次”
+
+## 结论清单
+
+可以明确认为“已足够，不需要优先再补”的：
+
+- `ConversationGAgent` dedup / retry 基础语义
+- relay token strip/re-enrich 基础机制
+- `TurnStreamingReplySink` 的大部分并发收尾行为
+- `ToolCallLoop` 的单体循环逻辑
+- `ChannelConversationTurnRunner` 的大部分 adapter / reaction / relay 分支
+
+可以明确认为“下一步最值得补”的：
+
+- `ConversationGAgent -> AgentRunGAgent` handoff 的 chain-level contract tests
+- `AgentRunGAgent` terminal 后重复信号 / cleanup / retry 组合幂等
+- `ConversationReplyGenerator` 与 `ToolCallLoop` / `ChatRuntime` 的 closeout 联动
+- `IChannelLlmReplyRunDispatcher` 这条新 seam 的结构护栏
+
+一句话总结：
+
+`feature/lark-bot` 现在缺的不是“更多测试”，而是**更少但更准的回归测试与护栏**。

Subject: [PATCH 083/113] Allow anonymous on Responses endpoints so manual
 bearer auth runs

The /v1/responses and /v1/responses/{id}/cancel handlers extract the
inbound Authorization bearer themselves and resolve the caller via
NyxID /me. Without .AllowAnonymous(), the host's FallbackPolicy
(installed by AddAevatarAuthentication) rejected opaque NyxID API
keys with an empty 401 from JwtBearer's default challenge before the
handler ever ran, breaking the issue #629 user flow behind the NyxID
proxy. PR #625's integration tests missed it because CreateAppAsync
uses a bare WebApplication.CreateBuilder and never wires the host's
auth pipeline. Add a regression test that uses AddAevatarAuthentication
to prove the handler is reached (structured authentication_required
JSON body, not an empty 401).

Subject: [PATCH 084/113] Carry NyxID bearer on typed
 CallerContext.Credentials, not Metadata
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PR #625's ResponsesEndpoints intentionally kept the inbound NyxID bearer
out of LLMRequest.Metadata to avoid leaking it through downstream logging
and telemetry sinks, but NyxIdLLMProvider's accessTokenAccessor is
hardcoded to () => null in BuildNyxIdFactory with the comment "token
comes exclusively from per-request metadata". The two design intents
contradicted: prod /v1/responses calls reached the LLM step and then
failed with NyxIdAuthenticationRequiredException because the bearer
was nowhere the provider could read it. RecordingLLMProvider does not
authenticate, so the integration tests passed while prod broke.

Extend LLMRequestCallerContext with an optional LLMRequestCallerCredentials
sub-record (currently NyxIdBearer only; designed so future delegation
tokens / identity JWTs are field additions, not new Metadata keys), and
let NyxIdLLMProvider.ResolveAccessToken read it first, fall back to the
existing Metadata key (kept so workflow / studio / LLMCallModule callers
keep working without simultaneous migration), then the host accessor.
Honors the author's logging-safety stance — Metadata stays string-bag
clean — while satisfying CLAUDE.md "核心语义强类型" for per-request auth.

NormalizeRequest in NyxIdLLMProvider was dropping CallerContext when
rebuilding the LLMRequest; the new typed-bearer test caught that during
revert-and-rerun, fixed by carrying it through.

Tests:
- MainnetResponsesEndpointsTests asserts CallerContext.Credentials.NyxIdBearer
  carries the inbound bearer AND Metadata.NotContainKey(NyxIdAccessToken)
  is preserved (typed channel vindicates the original intent).
- NyxIdLLMProviderRoutingTests gains two cases locking the resolution
  priority: typed wins, typed beats metadata.

Subject: [PATCH 085/113] Add /v1/models endpoint + OpenRouter-style
 multi-route resolution
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Stage 1: GET /v1/models fans out across every NyxID-routed LLM service the
caller can reach. Reuses the existing IUserLlmCatalogPort (Studio layer,
already wired into Mainnet via AddStudioCapability) to enumerate ready
services, then hits each service's /v1/models plane to obtain concrete
model strings — NyxID's /llm/status only exposes wildcard patterns
(`gpt-*`, `claude-*`...), so per-provider fan-out is the only way to
build a usable catalog. Per-provider /models endpoints work for the
OpenAI-compatible backends (anthropic, deepseek probed 200; others
backend-dependent — failures are silently skipped). Output uses bare
model ids for GatewayProvider services (back-compat with existing
callers sending plain `gpt-5.4` / `claude-3-5-sonnet-...`) and
`{slug}/{model}` for UserService / ProxyService routes.

Stage 2: ResponsesModelRouteParser splits `vendor/model` strings in
HandleCreateResponseAsync; matched slug pins NyxIdRoutePreference (which
NyxIdLLMProvider normalizes to /api/v1/proxy/s/{slug}) and the bare
model name flows to the LLM provider. Response-snapshot echoes still
carry normalized.Model so the client sees back what it sent. The
parser uses a slug-shape heuristic (lowercase + digits + hyphens,
length 2-64) and does NOT validate against the catalog — keeps
/v1/responses off the catalog HTTP critical path; unknown slugs get
a clean downstream 404. Catalog parity (only non-gateway sources emit
prefixes) ensures the heuristic and the catalog stay in sync.

Stage 1+2 must ship together: Stage 1 alone would be a lying surface
(client picks `chrono-llm/qwen-3`, sends it verbatim to /v1/responses,
NyxID gateway rejects unknown model name).

Tests:
- /v1/models happy path (OpenAI spec shape + aevatar extension fields,
  bearer-forward to aggregator).
- /v1/models without bearer → endpoint's structured 401 (matches the
  .AllowAnonymous() pattern from f09315da).
- Vendor-prefix model → strips prefix, pins NyxIdRoutePreference, snapshot
  echoes original (revert-and-rerun confirmed: actual `chrono-llm/qwen-3`
  vs expected `qwen-3` when parser disabled).
- Bare model → no route preference set.
- Non-slug-shaped prefix (`BadSlug/x`) → pass through verbatim.
- BuildModelsUrl Theory: GatewayProvider routes (already /v1-suffixed) vs
  UserService/ProxyService routes (need /v1 prepended).

Subject: [PATCH 086/113] Fix /v1/models fan-out URL for proxy-plane services
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ProxyService / UserService routes were 404-ing because BuildModelsUrl
appended /v1/models to RouteValue like /api/v1/proxy/s/chrono-llm,
producing /proxy/s/chrono-llm/v1/models — which NyxID then mapped to
https://llm.aelf.dev/v1/v1/models (double /v1) at the chrono-llm
backend. NyxID's DownstreamService.base_url already embeds the
upstream's /v1 segment, so the proxy plane only needs a single
appended /models. The same single-segment append correctly hits
gateway-plane routes too because their RouteValue is already /v1-
terminated. Append /models uniformly.

Verified by probing /api/v1/proxy/s/chrono-llm/models → 200 with 59
concrete model entries; /api/v1/proxy/s/chrono-llm/v1/models → 404.
After fix, /v1/models surfaces chrono-llm's 59 models alongside the
existing anthropic + deepseek groups.

Subject: [PATCH 087/113] Make /v1/models prefix every id; resolve vendor slug
 to RouteValue
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Stage 1: drop the source-dependent "bare for gateway, prefixed for proxy"
split. Every aggregated model entry now comes out as `{slug}/{model}`
regardless of NyxIdLlmProviderSource — matches OpenRouter's flat
`vendor/model` shape so clients can sort and group by id prefix
uniformly. NormalizeModelsBody is now internal-static, covered by unit
tests for both gateway-provider and proxy-service sources.

Stage 2: introduce IResponsesRouteResolver. When a request arrives with
a slug-shaped prefix, the resolver consults IUserLlmCatalogPort and maps
slug → RouteValue (full path: `/api/v1/llm/anthropic/v1` for gateway
providers, `/api/v1/proxy/s/chrono-llm` for proxy services). NyxIdRoutePreference
gets the full RouteValue, so NyxIdLLMProvider can route to the right
plane — `anthropic/claude-opus-4-7` no longer mis-routes to the
non-existent `/proxy/s/anthropic`. Catalog miss falls through to default
gateway routing with the model string preserved verbatim (NyxID gateway
picks backend by model name, or returns a clear downstream error).

Resolver caches per bearer with a 5-minute TTL; bearer is SHA256-hashed
before keying so raw tokens stay out of in-memory state. Cache tests
cover slug hit, slug miss, disallowed-service exclusion, TTL refresh,
and per-bearer isolation.

Bare model strings (no slash) continue to work — the parser returns no
slug, so the resolver isn't even consulted. Verified via revert-and-rerun:
both proxy-prefix and gateway-prefix tests go red with the resolver call
disabled (model stays prefixed, RoutePreference unset), green when
re-enabled.

37 tests pass.

Subject: [PATCH 088/113] =?UTF-8?q?Stop=20filtering=20/v1/models=20by=20Al?=
 =?UTF-8?q?lowed/Status=20=E2=80=94=20let=20downstream=20HTTP=20decide?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`NyxIdLlmServiceCatalogParser.ResolveProxyStatus` treats services with
`requires_connection=true + connected=false` (e.g. chrono-llm in prod) as
`Status=not_connected, Allowed=false`. That flag really means "user
hasn't bound a credential" — a UI hint — not "this route can't serve
requests": chrono-llm and similar shared-backend services are routable
for any caller's bearer because the backing LLM (e.g. llm.aelf.dev/v1)
is shared at the deployment level. Confirmed by invoking
`chrono-llm/gpt-5.5` and `llm-deepseek/deepseek-v4-pro` end-to-end with
the test API key (both 200 + full SSE delta/done/completed).

Aggregator: drop `Allowed` and `Status==ready` from IsReadyForFanOut;
keep only `RouteValue` presence. Fan-out attempts every catalog entry
with a route; a downstream 403/404 silent-skips. chrono-llm now
contributes its 59 concrete models to /v1/models.

Resolver: same change in BuildRouteMap. Stage 2 maps the slug even when
catalog flags it disallowed, so /v1/responses lets NyxID return an
honest 403 instead of aevatar pretending the slug doesn't exist.

Aevatar pod log trace (`-l app=aevatar-console-backend --tail=-1
--since=15m | grep proxy/s/...`) showed fan-out hitting every llm-*
slug but skipping chrono-llm entirely — that was the smoking gun.

37 tests pass; the disallowed-service test was inverted to assert
inclusion (matches new contract).

Subject: [PATCH 089/113] Forward upstream model metadata to /v1/models entries
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CC Switch / Codex / OpenRouter-spec clients read per-model
context_length / max_output_tokens / display_name / description to size
prompts and cap outputs. Aevatar's /v1/models had been emitting only
the OpenAI-spec minimum + a few aevatar extensions; the client falls
back to conservative defaults and prints
"Model metadata for `…` not found. Defaulting to fallback metadata;
this can degrade performance and cause issues."

Forward four optional fields from the upstream `/v1/models` response,
trying multiple field-name aliases to cover both shapes the upstreams
use today:

- `context_length` ← upstream `context_length` || `max_input_tokens`
- `max_output_tokens` ← upstream `max_output_tokens` || `max_completion_tokens` || `max_tokens`
- `display_name` ← upstream `display_name` || `name`
- `description` ← upstream `description` || `summary`

Anthropic's per-provider plane returns max_input_tokens + max_tokens +
display_name → aevatar now relays them, so anthropic models surface
rich metadata. DeepSeek / chrono-llm / vanilla OpenAI backends return
only the minimal shape — the fields stay null, JsonIgnoreCondition.WhenWritingNull
omits them from the JSON output, and aevatar refuses to invent metadata
it doesn't have (a UI warning is correct behavior in that case).

Tests cover anthropic shape, OpenRouter shape, and sparse-upstream
no-op. Revert-and-rerun: both forward tests go red when the field
extraction is replaced with null, confirming the new assertions actually
gate the forwarding behavior.

Subject: [PATCH 090/113] Accept OpenAI Responses built-in tool declarations
 alongside function tools
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CC Switch (and other Anthropic→OpenAI Responses translators) advertise
Claude Code tools as a mix of `{type: "function", name, parameters, …}`
function declarations and OpenAI built-in tool declarations like
`{type: "web_search_preview"}` / `{type: "file_search", vector_store_ids: […]}`
/ `{type: "code_interpreter"}` / `{type: "computer_use_preview"}`. The
built-in forms have no `name` or `function` block — they're routing
hints to the model provider, not custom function definitions.

Previously the normalizer required every tool entry to have a name,
so a single built-in declaration anywhere in the array failed the
whole request with `invalid_tools: "Each tool requires a non-empty
name."` — exactly what the user hit when configuring CC Switch
against `chrono-llm/gpt-5.5`.

Skip non-function-typed entries silently (aevatar's classifier only
owns forward / substitute / additive function tools), keep validating
name for function-type entries. Improve the error message to include
the failing tool index for easier diagnosis on future malformed
inputs.

Tests:
- A mixed array (`web_search_preview` + `file_search` + a real
  function tool `Bash`) now returns 200 and the LLM provider sees
  exactly the one function tool; built-ins are dropped.
- A function-type entry without a name still 400s with
  `function tool at index 1 requires a non-empty name`.

Revert-and-rerun confirmed the built-in pass-through test goes red
when the skip branch is disabled.

Subject: [PATCH 091/113] Fold function_call_output without
 previous_response_id; deepseek metadata fallback
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two issues surfaced when CC Switch users tried multi-turn tool conversations
on chrono-llm / llm-deepseek:

1. `function_call_output requires previous_response_id` 400 on the followup
   turn. CC Switch / Codex translating Claude Code's prior tool-result turn
   forwards `function_call_output` items in `input` but does NOT propagate
   `previous_response_id` — they don't model OpenAI's server-side session.
   Strict #629 §13 normalization rejected the request and the agent couldn't
   continue any multi-turn tool conversation.

   Fix: when `previous_response_id` is absent, fold `function_call_output`
   entries into the user prompt with synthetic `[tool_result call_id=…]`
   markers and clear ToolResults. Continuation contract still applies when
   the client actually sends `previous_response_id`.

2. `Model metadata for `llm-deepseek/deepseek-v4-pro` not found` warning
   from CC Switch — upstream deepseek `/v1/models` is OpenAI-spec minimal
   (no context_length / max_output_tokens), the no-hardcode rule forbids
   in-code defaults, but the user explicitly asked for "兜底" so requests
   don't get crippled by CC Switch's conservative fallback metadata.

   Fix: config-driven `Aevatar:Responses:ModelMetadataFallbacks`.
   Lookup precedence per entry: upstream fields → exact `{slug}/{model}`
   match → group-wide `{slug}` match. Fallback only fills nulls; never
   overwrites upstream values. Empty config = no-op. Default deployment
   ships with deepseek + llm-deepseek 64k/8k defaults in appsettings.json;
   deployment can override / remove. Stays out of code per the
   `feedback_no_hardcoded_metadata` rule that explicitly permits
   config-driven slug→config.

Tests cover both regressions + revert-and-rerun confirms the fold test
catches the exact `previous_response_required` 400 the user reported.

Subject: [PATCH 092/113] Add end-user runbook: configure cc-switch for Aevatar
 via NyxID

Covers nyxid CLI API key issuance, cc-switch codex provider TOML, and
end-to-end curl smoke test. Notes Aevatar is auto_connected so users
only add the LLM provider they want to route through it.

+# Aevatar Responses 接入指南：用 nyxid CLI 签发 API Key 并配置 cc-switch
+
+面向终端用户：在 cc-switch / Codex / 任意支持 OpenAI Responses 协议的客户端里，
+通过 NyxID 把流量打到 Aevatar，由 Aevatar 完成补全后回复客户端。
+
+> Aevatar 当前对外暴露的是 **OpenAI Responses 协议**（`/v1/responses`、`/v1/models`），
+> 还未实现 Anthropic Messages 协议。所以：
+> - ✅ Codex CLI、Cursor、OpenCode 等 Responses 客户端可以接入
+> - ❌ Claude Code（仅支持 Messages）暂时无法直连 Aevatar
+
+---
+
+## 1. 链路速览
+
+```
+cc-switch (codex app)
+   ↓ Authorization: Bearer nyx_xxx
+   ↓ POST /v1/responses
+NyxID proxy plane
+   https://nyx-api.chrono-ai.fun/api/v1/proxy/s/aevatar/v1/responses
+   ↓ 校验 API Key + allowed_services
+   ↓ 注入 X-NyxID-Delegation-Token（user 身份）
+Aevatar Responses API
+   https://aevatar-console-backend-api.aevatar.ai/v1/responses
+   ↓ 用 delegation token 经 NyxID 再调用 LLM provider
+NyxID LLM gateway / proxy
+   ↓ chrono-llm / llm-anthropic / llm-deepseek …
+真正的 LLM 上游
+   ↓ SSE / JSON 回流
+原路返回客户端
+```
+
+关键点：
+
+- 客户端只持有 **一把 NyxID API Key**，不直接接触任何 LLM 供应商凭据。
+- API Key 既用于校验 `nyx-api → aevatar` 这一跳，也会作为 delegation token 让 Aevatar
+  在下游再次回到 NyxID 完成实际的 LLM 调用。
+- Aevatar 自身不存任何 LLM key，所有计费、限流、撤销都集中在 NyxID 侧。
+
+---
+
+## 2. 前置条件
+
+- 已注册 NyxID 账号，本机安装好 `nyxid` CLI（`which nyxid` 应返回路径）。
+- NyxID 服务端：`https://nyx-api.chrono-ai.fun`
+- 本机安装好 cc-switch。
+
+登录（首次或换机时）：
+
+```bash
+nyxid login --base-url https://nyx-api.chrono-ai.fun
+nyxid whoami
+```
+
+---
+
+## 3. 添加你想用的 LLM 服务
+
+> **Aevatar 已经是 NyxID 的默认服务，每个 NyxID 用户登录后自动开通**（`auto_connected: true`，
+> 不出现在 `nyxid catalog list` 的 "Available Services" 里）。所以**不需要**
+> `nyxid service add aevatar`。
+
+你只需要再挂一个 **LLM provider**，让 Aevatar 下游能找到真实模型。任选其一，按需多加：
+
+```bash
+nyxid service add chrono-llm       # 团队共享网关，无需自带 key（最简单）
+nyxid service add llm-anthropic    # 自带 Anthropic key
+nyxid service add llm-deepseek
+nyxid service add llm-openai-codex
+
+# 确认已添加
+nyxid service list
+```
+
+> 之后在 cc-switch 里发请求时，会用 `chrono-llm/gpt-5.5`、
+> `llm-anthropic/claude-haiku-4-5` 这种 `<provider-slug>/<model>` 形式指定模型，
+> Aevatar 的 `/v1/models` 会把你账户下能用的全部列出来。
+
+---
+
+## 4. 用 nyxid CLI 签发 API Key
+
+最快路径（首次接入推荐，所有已添加的服务都放行）：
+
+```bash
+nyxid api-key create \
+  --name "cc-switch aevatar" \
+  --scopes proxy \
+  --platform codex \
+  --allow-all-services \
+  --expires-in-days 0
+```
+
+输出末尾会打印一次 **`nyx_...`** 形式的明文 Key，**只显示这一次**，复制保存。
+
+如果想最小权限收紧（推荐生产用）：先拿到所选 LLM 服务的 UserService.id，再用 `--allowed-services`：
+
+```bash
+# 取你要用的 LLM provider 的 UserService.id（aevatar 自动开通，不用列）
+nyxid service list --output json \
+  | jq -r '.keys[] | select(.slug=="chrono-llm") | .id'
+
+# 用这个 UserService ID 签发受限 Key
+nyxid api-key create \
+  --name "cc-switch aevatar (scoped)" \
+  --scopes proxy \
+  --platform codex \
+  --allowed-services <chrono-llm-user-service-id>
+```
+
+> ⚠️ 必须用 `nyxid service list` 里的 UserService.id，不是 `nyxid catalog list`
+> 里的目录 id。两者不同；后者会得到 `api_key_scope_forbidden_legacy`。
+>
+> 如果收紧后访问 `/proxy/s/aevatar/*` 反而 403，把 aevatar 的 UserService.id
+> 也加进 `--allowed-services` 兜底——auto_connected 服务理论上应被 proxy 默认放行，
+> 但不同版本 NyxID 的行为可能不同。
+
+查看与吊销：
+
+```bash
+nyxid api-key list
+nyxid api-key delete <key-id>
+```
+
+---
+
+## 5. 配置 cc-switch（codex / Responses 形态）
+
+打开 cc-switch → **Codex** 标签 → 新建 Provider，填写如下字段：
+
+- **Name**：`Aevatar`
+- **OPENAI_API_KEY**：第 4 步生成的 `nyx_...`
+- **Config (toml)**：
+
+```toml
+model_provider = "custom"
+model = "chrono-llm/gpt-5.5"          # 改成你实际想用的 <provider-slug>/<model>
+disable_response_storage = true
+
+[model_providers]
+[model_providers.custom]
+name = "custom"
+wire_api = "responses"
+requires_openai_auth = true
+base_url = "https://nyx-api.chrono-ai.fun/api/v1/proxy/s/aevatar/v1"
+```
+
+要点：
+
+- **`wire_api = "responses"`** 必填——Aevatar 只讲 Responses 协议。
+- **`base_url`** 必须停在 `/v1`，cc-switch 会自动追加 `/responses`、`/models`。
+- `model` 形如 `<nyxid-service-slug>/<model-name>`；可用清单见下一步。
+
+保存并切到这个 Provider。
+
+---
+
+## 6. 端到端冒烟测试
+
+不进 cc-switch 也能验证（直接 curl）：
+
+```bash
+API_KEY="nyx_xxxxxxxxxxxxxxxx"
+BASE="https://nyx-api.chrono-ai.fun/api/v1/proxy/s/aevatar/v1"
+
+# 1) 列出当前账户在 Aevatar 视角下可用的模型
+curl -sS "$BASE/models" \
+  -H "Authorization: Bearer $API_KEY" | jq '.data[].id' | head -20
+
+# 2) 发一次最简 Responses 请求
+curl -sS "$BASE/responses" \
+  -H "Authorization: Bearer $API_KEY" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "model": "chrono-llm/gpt-5.5",
+    "input": "ping"
+  }' | jq
+```
+
+正常返回里应包含 `id`、`output[].content[].text` 等 Responses 标准字段。
+
+---
+
+## 7. 常见问题排查
+
+| 现象 | 多半原因 | 解法 |

 Claude Code
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds §6 to the cc-switch runbook describing the planned /v1/messages endpoint:
capability matrix vs /v1/responses, protocol-mismatch rationale (Messages is
stateless, aevatar runtime is stateful — surface is intentionally narrow), and
the cc-switch Claude-tab config to use once it lands. Renumbers downstream
sections and updates the troubleshooting row that previously said Messages was
not on the roadmap.

-## 6. 端到端冒烟测试
+## 6. 接入 Claude Code（Messages 协议，路径 B，计划中）
+
+> ⚠️ **状态：设计中，尚未实现。本节描述的是规划接入路径，不是当前可用的能力。**
+
+Claude Code 只支持 Anthropic Messages 协议，aevatar 计划新增 `/v1/messages` 端点作为
+**无状态视图（stateless facade）** 暴露给这类客户端。这条路是有意做"窄"的——
+权威的异步编排入口仍然是 `/v1/responses`，不要把 `/v1/messages` 当成它的同级替代品。
+
+### 能力对比
+
+| 能力 | `/v1/responses` | `/v1/messages` (路径 B) |
+|------|----------------|------------------------|
+| 模型路由（`<slug>/<model>`） | ✅ | ✅ |
+| 客户端发请求 / 收响应 | ✅ | ✅ |
+| 工具循环（NyxID 工具） | ✅ 服务端可观察 | ⚠️ 服务端闭环跑完，客户端只见最终文本 |
+| Session 连续性（`previous_response_id`） | ✅ | ❌ 每轮都是新 run |
+| Background 长任务 | ✅ | ❌ Anthropic 协议无对位字段 |
+| Reasoning blocks 透传 | ✅ | ❌ 协议有损 |
+
+### 协议错位简述
+
+Messages 是**无状态**协议，aevatar 是**有状态**运行时——路径 B 选择承认错位、把表面做窄：
+
+- Messages 要求客户端每轮重传完整 `messages` 数组；aevatar 不在这条表面上维护 session，
+  每个请求都是一次性 run。
+- Messages 的 `tool_use` 块协议假设客户端执行工具；NyxID 工具不在客户端侧，
+  aevatar 选择在服务端内闭环跑完工具循环，只回吐最终文本。
+- 想要完整异步编排能力（session、background、可观察工具循环），用 `/v1/responses`。
+
+### 计划中的 cc-switch 配置（合入后即用）
+
+cc-switch 的 **Claude** 标签新建 Provider：
+
+- **Name**：`Aevatar (Messages)`
+- **ANTHROPIC_BASE_URL**：`https://nyx-api.chrono-ai.fun/api/v1/proxy/s/aevatar`
+- **ANTHROPIC_AUTH_TOKEN**：第 4 步生成的 `nyx_...`（和 Codex 那把 key 同源）
+- **ANTHROPIC_MODEL**：`llm-anthropic/claude-haiku-4-5`（或其它 `<nyxid-service-slug>/<model>`）
+
+要点：
+
+- 用 `ANTHROPIC_AUTH_TOKEN`（Bearer 头），**不要**用 `ANTHROPIC_API_KEY`（`x-api-key` 头）——
+  NyxID proxy plane 只识别 `Authorization: Bearer`。
+- `ANTHROPIC_BASE_URL` 停在 `/aevatar` 这一级（不带 `/v1`），Claude Code 自行拼 `/v1/messages`；
+  实际拼接行为以实现 PR 落地时验证为准。
+- 模型字段沿用 `<slug>/<model>` 形式，与 Responses 那条一致。
+
+合入前不要在客户端配——会直接 404。

Subject: [PATCH 095/113] Rename ResponseSessionGAgent to LlmSessionGAgent
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The actor state, proto, and ports are protocol-neutral — they carry
scope/owner/status and forwarded tool calls without any Responses-only
fields. Naming them ResponseSession blocks reuse by /v1/messages
(Anthropic Messages, planned Path B) and misleads readers into thinking
the actor is OpenAI-Responses-specific.

Mechanical rename across 25 files (400 lines changed, 400 added):
  ResponseSession        -> LlmSession
  response_session(s)    -> llm_session(s)
  RESPONSE_SESSION_      -> LLM_SESSION_
  IResponseSession*      -> ILlmSession*

Field `response_id` is kept on the record because Path A (Responses)
keeps emitting OpenAI-style response ids on the wire; Path B will
synthesize its own session identifier into the same field.

Subject: [PATCH 096/113] Add /v1/messages (Anthropic Messages) endpoint as
 stateless Path B facade
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Path B is a stateless facade over the same LlmSessionGAgent +
NyxIdLLMProvider + IResponsesCompletionApplicationService pipeline that
serves /v1/responses. No new GAgent type is introduced — the previously
renamed LlmSessionGAgent is protocol-neutral and the facade reuses it
verbatim. cc-switch users running Claude Code can now point at the
Aevatar/NyxID base URL and get an end-to-end Messages-protocol session.

Surface (src/Aevatar.Mainnet.Host.Api/Messages/):
  POST /v1/messages         AllowAnonymous, manual bearer extraction,
                            mirrors /v1/responses auth model
  - non-streaming           returns Anthropic message envelope JSON
  - streaming               emits Anthropic SSE schedule:
                              message_start
                              content_block_start (text or tool_use)
                              content_block_delta (text_delta /
                                                  input_json_delta)
                              content_block_stop
                              message_delta
                              message_stop

Lossy translation boundary (documented inline + tested):
  - thinking block       -> ChatMessage.ReasoningContent (lossless)
  - tool_use block       -> ToolCall.ArgumentsJson      (text args lossless;
                                                       image args dropped)
  - tool_result block    -> ChatMessage.Tool(callId, output) (text only)
  - cache_control        -> ignored in v1

Stateless contract: Anthropic Messages has no previous_response_id, so
each POST opens + closes its own LlmSession (24h TTL kept for parity
with Path A audit/projection).

Tests (test/Aevatar.Hosting.Tests/MainnetMessagesEndpointsTests.cs):
  PostMessages_NonStreaming_ShouldReturnAnthropicMessageEnvelope
  PostMessages_Streaming_ShouldEmitAnthropicSseFrames
  PostMessages_WithToolCall_ShouldEmitToolUseContentBlock
  PostMessages_WithoutBearer_ShouldReturn401WithAnthropicErrorEnvelope
  PostMessages_WithToolResultBlockInUserContent_ShouldFlattenIntoToolRoleMessage

Subject: [PATCH 099/113] Add ADR-0021 lark reply chain completion semantics

Defines the four-phase chain contract (accepted/committed/delivered/finalized)
across ConversationGAgent / IChannelLlmReplyRunDispatcher / AgentRunGAgent
with a single observable state per phase. Locks in:

- AgentRunStatus 5-state proto enum, with REPLY_HANDED_OFF replacing
  the reply_dispatched bool (which becomes reserved).
- ConversationState.last_reply_delivery single field carrying
  user-visible delivery ack from the channel sink.
- Typed DispatchOutcome on IChannelLlmReplyRunDispatcher.DispatchAsync
  so the synchronous return point only promises accepted.
- finalized as an absorbing state; late/stale signals must no-op.

Companion docs/canon/lark-reply-completion-semantics.md adds
sequence diagrams, failure matrix, state machine views, and the
implementation checklist used by the upcoming code-side commits
(issues #647 / #648 / #649).

+# ADR-0021: Lark Reply Chain Completion Semantics
+
+## Context
+
+Lark reply 主链路 `ConversationGAgent → IChannelLlmReplyRunDispatcher → AgentRunGAgent → ConversationReplyGenerator → ChatRuntime` 跨多个 actor handoff。当前各层完成态语义靠读代码理解：
+
+- dispatcher 同步返回 ≠ user 已 delivered
+- committed event ≠ 消费方已收到
+- `AgentRunGAgent` terminal ≠ chain 已 finalized
+- streaming closeout (`Usage` / `FinishReason` / `IsLast` chunk) 是 round-local 还是 stream-local 无共识
+
+Issues #647 / #648 / #649 都源于这一根本：契约不显式，每层承诺都可能被误读为强保证；后续测试也容易把目标态假设误写成当前既有不变量。
+
+## Decision
+
+### 1. 顶层 4 阶段（chain-level contract）
+
+跨 actor 的 reply chain 完成必须经过四个有序阶段。每个阶段有唯一推进方、唯一可观察 state、明确承诺范围：
+
+| 阶段 | 推进方 | 同步入口 | 异步事件 | 可观察 state | 承诺 |
+|---|---|---|---|---|---|
+| **accepted** | dispatcher | `DispatchAsync` return | `NeedsLlmReplyEvent` appended | `ConversationState.PendingLlmReply` | 已收到 & 入 actor inbox stream；**不**承诺 LLM 已开始处理 |
+| **committed** | `AgentRunGAgent` | — | `AgentRunReplyProducedEvent` persisted | `AgentRunState.Status = REPLY_PRODUCED` | LLM 已产出 & state event 已落库；**不**承诺消费方已收到 |
+| **delivered** | `ConversationGAgent` + channel sink | — | `LlmReplyDeliveredEvent` (新增) | `ConversationState.LastReplyDelivery.{outcome, channel_message_id, ack_at_unix_ms}` | channel sink 已 ack；**user-visible** |
+| **finalized** | `AgentRunGAgent` + `ConversationGAgent` | — | `ConversationTurnCompletedEvent` + `AgentRunState.cleanup_completed_at != 0` | terminal status + cleanup 已完 | 所有副作用收尾；**吸收态** |
+
+**关键不变量**：
+
+- 任一阶段失败必须转化为 `DROPPED` / `FAILED` 终态，不允许"卡在中间"
+- 上一阶段达成是下一阶段的**必要不充分**条件（accepted 后下游可在任何阶段进入 dropped/failed）
+- **finalized 是吸收态**：进入后所有 ready / dropped / failed / cleanup signal 必须 no-op；late / stale signal 不改动最终状态
+
+### 2. `AgentRunGAgent` 5 态（actor-internal status）
+
+替代当前 `STARTED / REPLY_PRODUCED / DROPPED / FAILED` 4 态加 `reply_dispatched` bool 的隐式表达：
+
+```proto
+enum AgentRunStatus {
+  AGENT_RUN_STATUS_UNSPECIFIED = 0;
+  STARTED                      = 1;
+  REPLY_PRODUCED               = 2;  // = chain.committed
+  REPLY_HANDED_OFF             = 3;  // 替代 reply_dispatched bool；LlmReplyReadyEvent 已被 ConversationGAgent 消费
+  DROPPED                      = 4;
+  FAILED                       = 5;
+}
+```
+
+**关键消歧**：`AgentRunStatus.REPLY_HANDED_OFF ≠ chain.delivered`。
+
+- `REPLY_HANDED_OFF` = actor-to-actor handoff 完成（`AgentRunGAgent` 视角能观察的最远状态）
+- `chain.delivered` = user-visible delivery 完成（由 `ConversationGAgent` 拥有）
+- 前者是后者的**必要不充分**条件
+
+`reply_dispatched` bool 字段标记 `reserved`，不物理删除以避免破坏既有 event store。新代码不再读写。
+
+终态判定 helper：
+
+```csharp
+public static bool IsTerminal(AgentRunState s) =>
+    s.Status == AgentRunStatus.Dropped
+ || s.Status == AgentRunStatus.Failed
+ || s.Status == AgentRunStatus.ReplyHandedOff;
+```
+
+所有 ready / dropped / failed / cleanup handler 入口必须先 `IsTerminal` 短路。
+
+### 3. `ConversationGAgent` 新增 delivery tracking
+
+为把"当前隐式的 lark API 返回值"显式化为 user-visible delivered 信号：
+
+```proto
+message ReplyDeliveryStatus {
+  oneof outcome {
+    Pending pending          = 1;
+    Delivered delivered      = 2;
+    DeliveryFailed failed    = 3;
+  }
+  string run_id              = 10;
+  message Pending        { int64 started_at_unix_ms = 1; }
+  message Delivered      { int64 acked_at_unix_ms   = 1; string channel_message_id = 2; }
+  message DeliveryFailed { int64 failed_at_unix_ms  = 1; string error_code = 2; string error_message = 3; }
+}
+
+message ConversationState {
+  // ... existing fields ...
+  ReplyDeliveryStatus last_reply_delivery = N;
+}
+```
+
+**单字段而非 `map<run_id, ReplyDeliveryStatus>`**：旧 turn 的 delivery 状态对推进 chain 已无意义，多 turn 历史可通过 event log 重建；单字段降低 state size，避免持久化开销线性增长。
+
+落地位置：
+
+- 非 streaming 路径：`ConversationGAgent.RunLlmReplyAsync` (cs:458) 调用 lark API 后 raise event
+- streaming 路径：`HandleLlmReplyStreamChunkAsync` (cs:532) / `HandleLlmReplyCardStreamChunkAsync` (cs:546) 在 final chunk emit 之后 raise event
+- 失败路径：lark API 4xx/5xx / 超时 → raise `LlmReplyDeliveryFailedEvent`
+
+### 4. Dispatcher 返回值显式化
+
+```csharp
+public interface IChannelLlmReplyRunDispatcher
+{
+    Task<DispatchOutcome> DispatchAsync(NeedsLlmReplyEvent evt, CancellationToken ct = default);
+}
+
+public sealed record DispatchOutcome(
+    DispatchPhase Phase,
+    string CommandId,
+    string? RunActorId,
+    long AcceptedAtUnixMs);
+
+public enum DispatchPhase
+{
+    Accepted = 0,
+    RejectedStale = 1,        // request age > MaxRunRequestAgeMs
+    RejectedDuplicate = 2,    // dedup hit on CommandId
+}
+```
+
+**`DispatchPhase` 只能取 `Accepted` / `Rejected*`**，**不允许** `Committed` / `Delivered` — dispatcher 不承诺 downstream 任何事。
+
+**兼容性**：接口 `IChannelLlmReplyRunDispatcher` 完全仓库内部消费，无 NuGet 包发布；调用方 3 处（`ConversationGAgent.cs:349` + 2 处测试 mock）随 ADR 适配。无线上兼容性风险。
+
+### 5. 同步 vs 异步承诺矩阵
+
+| 调用点 | 同步返回承诺 | 异步可观察 |
+|---|---|---|
+| `IChannelLlmReplyRunDispatcher.DispatchAsync` return | `DispatchPhase.Accepted` (仅入 inbox) | `AgentRunReplyProducedEvent` / `AgentRunDroppedEvent` / `AgentRunFailedEvent` |
+| `AgentRunGAgent.HandleAgentRunStartRequested` 返回 | run 已接收 | committed → handed_off |
+| `ConversationGAgent.HandleLlmReplyReadyAsync` 返回 | handed_off 达成（ack from AgentRunGAgent 视角） | delivered → finalized |
+| 对外 HTTP `/v1/messages` 等 | accepted 等价语义 | client 自行 poll readmodel |
+
+**禁止**任何同步调用点承诺"committed"或更强阶段；强保证只能通过异步事件 / readmodel 观察。
+
+### 6. 与 #648 / #649 的桥接
+
+- **#648 streaming closeout contract** = committed→delivered 阶段内部细节。本 ADR 约束：
+  - terminal signal **stream-local**（外部消费方只见一次 `IsLast = true` chunk）
+  - `Usage` / `FinishReason` 必须挂在最后一个 chunk 上
+  - 若 provider 在 `IsLast` 之前先发 `Usage`，runtime **重排**为最后一个 chunk
+  - multi-round tool use 的 round-level terminal 不向外暴露
+- **#649 terminal idempotency** = finalized 吸收态在 `AgentRunGAgent` 的实现：
+  - `IsTerminal` helper 统一收口（替代 cs:114-124 散落的 ad-hoc 判断）
+  - 所有 handler 入口先短路终态
+  - cleanup 显式幂等（`cleanup_completed_at != 0` 即视为已完成，no-op）
+  - stale signal 校验统一通过 `commandId` + `runId` + `MaxRunRequestAgeMs`
+
+## Consequences
+
+### 必要变更
+
+1. `agent_run.proto`：扩 `AgentRunStatus` enum 加 `REPLY_HANDED_OFF`；`reply_dispatched` bool 标记 reserved
+2. `conversation_state.proto`：新增 `ReplyDeliveryStatus` 消息 + `last_reply_delivery` 字段
+3. 新增 domain event：`LlmReplyDeliveredEvent` / `LlmReplyDeliveryFailedEvent`
+4. `IChannelLlmReplyRunDispatcher.DispatchAsync` 改返回 `Task<DispatchOutcome>`；新增 `DispatchOutcome` record + `DispatchPhase` enum
+5. `AgentRunGAgent` 把 `Status==ReplyProduced && reply_dispatched==true` 重写为 `Status==REPLY_HANDED_OFF`；新增 `IsTerminal` helper
+6. `ConversationGAgent.RunLlmReplyAsync` + streaming chunk path 在 lark API 调用后 raise delivery event 落地 `last_reply_delivery`
+7. 配套 `docs/canon/lark-reply-completion-semantics.md`：详细可观察 state 表 + 时序图 + 跨阶段故障矩阵
+
+### 不做
+
+- 不引入显式 `finalized` status 字段 — terminal status (`DROPPED` / `FAILED` / `REPLY_HANDED_OFF`) + `cleanup_completed_at != 0` 组合判定
+- 不动 channel sink 内部 retry 策略（属 #649 实现范畴）
+- 不引入 multi-turn delivery 历史（用 event log 重建即可）
+
+### 影响面
+
+- `IChannelLlmReplyRunDispatcher.DispatchAsync` 调用方 3 处需适配新返回值（生产 1 + 测试 mock 2），行为不变
+- 现有 reply chain 测试约 5+ 个需补 delivery event 断言（评估时认领）
+- 后续 #596 run-actor continuation 重构须在此契约下进行（不与本 ADR 冲突）
+- event store 兼容：`reply_dispatched` reserved 保留，旧 event 可读
+
+## Open Questions
+
+- multi-channel sink（Lark / Telegram）共享同一 `ReplyDeliveryStatus` 结构 — 默认共享，错误码 `error_code` 字符串承载平台差异
+- delivery 失败的 retry 归属：channel sink 内部 retry（建议）vs reply chain 层 retry — 待 #649 实现时定夺
+- `cleanup_completed_at` 字段足够 vs 引入独立 `AgentRunCleanupCompletedEvent` — 倾向字段，event 仅在跨 actor 通知时引入
+

+
+## 2. 可观察 State 表
+
+每个阶段必须可通过下列字段/事件**单一**可观察。任何"靠 X 推断 Y"都视为契约违反。
+
+| 阶段 | 推进 actor | state 字段 | trigger event | 反例（不可作为观察源） |
+|---|---|---|---|---|
+| **accepted** | dispatcher → ConversationGAgent | `ConversationState.pending_llm_reply.{command_id, requested_at_unix_ms}` | `NeedsLlmReplyEvent` appended | dispatcher log line、内存计数器 |
+| **committed** | AgentRunGAgent | `AgentRunState.status = REPLY_PRODUCED`<br/>`AgentRunState.reply_produced_at_unix_ms` | `AgentRunReplyProducedEvent` persisted | LLM provider 返回值、stream channel close |
+| **delivered** | ConversationGAgent + channel sink | `ConversationState.last_reply_delivery.delivered.{acked_at_unix_ms, channel_message_id}` | `LlmReplyDeliveredEvent` | lark API 返回 200 但未 raise event、日志行 |
+| **finalized** | AgentRunGAgent + ConversationGAgent | `AgentRunState.status ∈ {DROPPED, FAILED, REPLY_HANDED_OFF}`<br/>`AgentRunState.cleanup_completed_at != 0`<br/>`ConversationTurnCompletedEvent` 已 raise | 终态事件 + `AgentRunCleanupCompletedEvent`（可选） | 进程内 dictionary、回调"已 schedule" |
+
+> 注：`REPLY_HANDED_OFF` 不直接证明 `chain.delivered` — 还需 `last_reply_delivery.delivered != null`。本表把它列在 finalized 列是因为 finalized 是 AgentRunGAgent 视角的终态。

+
+| 故障发生时所处阶段 | 故障类型 | 终态 status | last_reply_delivery | 上抛事件 | 责任 actor |

+    end note
+```
+
+## 8. Streaming Closeout 契约（#648 实现侧）
+
+`ChatRuntime.ChatStreamAsync` 对消费方（`ConversationReplyGenerator`）的契约：
+
+- **Stream-local terminal**：消费方在一次 `ChatStreamAsync` 调用中**只见一次** `LLMStreamChunk { IsLast = true }`。multi-round tool use 的 round-level terminal **不向外暴露**，runtime 内部 fold。
+- **Usage / FinishReason 挂位**：必须挂在最后一个 chunk 上（即 `IsLast = true` 的 chunk）。
+- **Provider 早发 Usage 的处理**：若 provider 在 round 中段先发了 `Usage` 而 `IsLast = false`，runtime 必须**重排**：暂存 Usage，向消费方先发 delta chunks，待真正结束再合并到最后一个 `IsLast = true` chunk。
+- **Warning 不视为 terminal**：长度截断 (`ToolCallLoop.IsLengthTruncated`) 是 round-level 信号，由 runtime 决定后续行为，不映射到外部 IsLast。
+- **Tool-result chunk 不视为 terminal**：每轮 round 间的 `\n\n` separator chunk 与 tool-call payload chunk 都 `IsLast = false`。
+- **Closeout 路径单一**：channel writer close 必须先 emit 最后一个 `IsLast = true` chunk 再 close，**不允许**靠"reader 见底"隐式终结。
+
+## 9. Terminal Idempotency 契约（#649 实现侧）
+
+`AgentRunGAgent` 所有 handler 入口必须遵守：
+
+```csharp
+internal static bool IsTerminal(AgentRunState s) =>
+    s.Status == AgentRunStatus.Dropped
+ || s.Status == AgentRunStatus.Failed
+ || s.Status == AgentRunStatus.ReplyHandedOff;
+```
+
+**入口规则**：
+1. `HandleAgentRunStartRequested`：终态 → schedule cleanup（不重启 LLM），return
+2. `HandleLlmReplyReadyAsync` 内部 ack handler：终态 → log "stale-after-terminal"，return
+3. `HandleAgentRunDroppedAsync` / `HandleAgentRunFailedAsync`：终态 → log，return
+4. `ScheduleTerminalCleanupAsync`：`cleanup_completed_at != 0` → no-op
+5. `ReDispatchProducedReplyAsync`：终态 → 取消未来 retry，return
+
+**Stale signal 判定**：
+- 通过 `commandId` 不一致 → 视为 stale
+- 通过 `runId` 不一致 → 视为 stale
+- 通过 `nowMs - request.RequestedAtUnixMs > MaxRunRequestAgeMs` → 视为 stale，但仅在 STARTED 入口检查
+
+**禁止**：
+- 在终态 actor 上推进任何 state machine 边
+- 在终态 actor 上发起新的 redispatch / callback schedule
+- 通过 `lock` / `ConcurrentDictionary` 维护 "is this signal stale" 的内存字典（破坏 Actor 单线程事实源）
+
+## 10. 实现 Checklist
+
+- [ ] `agents/Aevatar.GAgents.NyxidChat/Protos/agent_run.proto`：扩 `AgentRunStatus` 加 `REPLY_HANDED_OFF`；`reply_dispatched` 标 `reserved`；加 `cleanup_completed_at`、`reply_produced_at_unix_ms`
+- [ ] `agents/Aevatar.GAgents.Channel.Runtime/Protos/conversation_state.proto`：新增 `ReplyDeliveryStatus` 消息 + `ConversationState.last_reply_delivery` 字段
+- [ ] 新增 domain event：`LlmReplyDeliveredEvent` / `LlmReplyDeliveryFailedEvent`（在 `Aevatar.GAgents.Channel.Runtime`）
+- [ ] `IChannelLlmReplyRunDispatcher.DispatchAsync` 改 `Task<DispatchOutcome>`；新增 `DispatchOutcome` / `DispatchPhase`
+- [ ] `AgentRunDispatcher` 实现按新签名返回 `Accepted{commandId, runActorId, acceptedAtMs}` / `RejectedStale` / `RejectedDuplicate`
+- [ ] `AgentRunGAgent`：
+  - [ ] 新增 `IsTerminal()` helper
+  - [ ] 替换 cs:114-124 隐式终态判定
+  - [ ] 所有 handler 入口加 `IsTerminal()` short-circuit
+  - [ ] `reply_dispatched` bool 读改 `Status == REPLY_HANDED_OFF`，写改 `RaiseEvent(LlmReplyHandedOffEvent)`
+  - [ ] `ScheduleTerminalCleanupAsync` 在完成时 raise `AgentRunCleanupCompletedEvent` 或直接置位 `cleanup_completed_at` 字段
+- [ ] `ConversationGAgent`：
+  - [ ] `RunLlmReplyAsync` (cs:458) 成功后 raise `LlmReplyDeliveredEvent`，失败 raise `LlmReplyDeliveryFailedEvent`
+  - [ ] streaming chunk path (cs:532, cs:546) 在 final chunk 编辑成功后 raise `LlmReplyDeliveredEvent`
+  - [ ] handler `HandleLlmReplyReadyAsync` (cs:422) 收到事件后短路重复 ack
+- [ ] `ChatRuntime.ChatStreamAsync` (`src/Aevatar.AI.Core/Chat/ChatRuntime.cs:208`)：
+  - [ ] 实现 Usage 重排（early-usage buffer + merge to last chunk）
+  - [ ] 保证 stream-local 唯一 `IsLast = true` chunk
+- [ ] 测试：
+  - [ ] `DispatchOutcome` 三态各 1 测试
+  - [ ] AgentRunGAgent terminal short-circuit 五类 late signal 各 1 测试
+  - [ ] `ConversationGAgent` 失败 delivery 路径测试（lark 4xx / 5xx）
+  - [ ] `ChatRuntime` Usage 重排测试（provider 中段发 Usage）
+  - [ ] reply chain happy path 端到端断言新事件序列
+
+## 11. 反例（implementation smells）
+
+下列模式视为契约违反，应在 review 时拒收：
+
+- 调用方依赖 `DispatchAsync` 返回 `Task`（无 `DispatchOutcome`）做后续推进决定
+- 任何 handler 内通过 `_pendingRuns.ContainsKey(runId)` 或类似进程内字典判断 stale
+- 在 `ConversationGAgent` 内直接调用 lark API 但不 raise delivery event
+- `AgentRunGAgent` 在 `Status == DROPPED` 后仍执行 `ScheduleTerminalCleanupAsync` 内部副作用
+- `ChatRuntime` 对外暴露多个 `IsLast = true` chunk（multi-round 时各 round 都发 terminal）
+- 用 `reply_dispatched` bool 替代 `Status == REPLY_HANDED_OFF` 做新代码判断
+

Subject: [PATCH 100/113] Apply ADR-0021 proto + dispatcher contract extensions

Lands the chain-level contract pieces of ADR-0021 that the rest of the
reply chain work depends on:

agent_run.proto
  - AgentRunStatus gains AGENT_RUN_STATUS_REPLY_HANDED_OFF.
  - AgentRunGAgentState.reply_dispatched (field 12) marked reserved; the
    explicit status replaces the implicit bool. Legacy event replay now
    promotes straight to REPLY_HANDED_OFF.
  - New cleanup_completed_at_unix_ms field (combined with terminal status,
    this is the chain.finalized observable).
  - New AgentRunCleanupCompletedEvent for the terminal-cleanup write.

conversation_state.proto / conversation_events.proto
  - New ReplyDeliveryStatus message (Pending / Delivered / DeliveryFailed)
    on ConversationGAgentState.last_reply_delivery as the
    chain.delivered observable.
  - New LlmReplyDeliveredEvent + LlmReplyDeliveryFailedEvent that drive
    ConversationGAgent into those outcomes.

IChannelLlmReplyRunDispatcher
  - DispatchAsync now returns Task<DispatchOutcome> with a typed phase
    (Accepted / RejectedStale / RejectedDuplicate). The interface has no
    NuGet consumers and the three in-repo call sites are adapted in this
    commit; behaviour is preserved.

AgentRunDispatcher
  - Performs a cheap freshness check at the boundary (mirrors
    AgentRunGAgent.MaxRunRequestAgeMs) and returns RejectedStale instead
    of enqueuing requests that the run actor would only drop.

AgentRunGAgent
  - All read sites of State.ReplyDispatched move to status checks:
    REPLY_HANDED_OFF replaces (ReplyProduced && ReplyDispatched).
  - ApplyReplyProduced legacy-event path promotes status to
    REPLY_HANDED_OFF; ApplyReplyDispatched promotes committed ->
    handed-off; the new-event path leaves status at REPLY_PRODUCED until
    the dispatched event lands.

Tests
  - ConversationGAgentDedupTests RecordingRunDispatcher mock adapted to
    the new return type.
  - AgentRunGAgentTests assertions migrated from ReplyDispatched bool to
    explicit REPLY_PRODUCED / REPLY_HANDED_OFF status expectations.

Docs
  - canon checklist fixed to reflect that the handed-off transition uses
    the existing AgentRunReplyDispatchedEvent (no new event required) and
    that AgentRunCleanupCompletedEvent drives cleanup_completed_at.

Subject: [PATCH 101/113] Persist LlmReplyDelivered / LlmReplyDeliveryFailed
 events on ConversationGAgent
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Makes ADR-0021 chain.delivered observable from
ConversationGAgentState.last_reply_delivery instead of inference from
log lines or channel sink return codes. ConversationGAgent now:

  * Persists LlmReplyDeliveredEvent before ConversationTurnCompletedEvent
    on the non-streaming success path (HandleLlmReplyReadyAsync ->
    RunLlmReplyAsync) and on the streaming completion path
    (PersistStreamedCompletionAsync — which is the unified streaming
    sink that all partial / full / failure-self-heal branches funnel
    through, so any user-visible content counts as delivered).
  * Persists LlmReplyDeliveryFailedEvent before
    ConversationContinueFailedEvent on the non-streaming failure path
    so DeliveryFailed carries the structured reason while the
    chain-finalizing failure event is still last.
  * Wires two new state-matcher entries (ApplyLastReplyDelivered /
    ApplyLastReplyDeliveryFailed) that populate
    ConversationGAgentState.last_reply_delivery — single-field by
    design, multi-turn history reconstructable from event log.

Raise order is delivered → completed (resp. failed) so existing
consumers of "events.Last() is ConversationTurnCompletedEvent /
ConversationContinueFailedEvent" stay correct.

Tests
  - HandleLlmReplyReadyAsync_WhenDuplicateCorrelationId_CollapsesToSingleOutboundCommit
    now expects 3 events (the new Delivered event sits between
    NeedsLlmReplyEvent and TurnCompleted), with a regression check
    that LlmReplyDeliveredEvent is present in the log.

Subject: [PATCH 102/113] Place ADR-0021 streaming closeout at the actor edge
 (issue #648)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ADR-0021 §6 / canon §8 streaming closeout contract — stream-local
terminal, aggregated Usage on a single closeout point, FinishReason
visibility — implemented at the run-actor boundary instead of inside
ChatRuntime. Respects aevatar#596 phasing: ChatRuntime stays a
transitional local loop (Phase A); the run-actor edge owns the
contract surface (Phase A targets) so the eventual ChatRuntime
tear-down in Phase B does not need to renegotiate it.

IConversationReplyGenerator
  - GenerateReplyAsync now returns Task<ConversationReplyResult> with
    Text, Usage (ReplyTokenUsage), and FinishReason. ReplyTokenUsage is
    a Channel.Runtime-local projection mirroring AI.Abstractions.TokenUsage
    so Channel.Runtime does not gain a reverse layer dependency on
    AI.Abstractions (CLAUDE.md "依赖反转").

NyxIdConversationReplyGenerator
  - Aggregates Usage across all internal LLM rounds (tool-call loop)
    via SumUsage and tracks the last non-empty FinishReason. The
    foreach over the ChatRuntime stream extracts both before falling
    through to the DeltaContent-only forwarding to the streaming sink,
    so neither metric is dropped when DeltaContent is empty.

AgentRunGAgent
  - Consumes ConversationReplyResult at the run-actor edge and logs
    the closeout once (runId / correlation / prompt|completion|total
    tokens / finishReason). LlmReplyReadyEvent semantics unchanged
    until a follow-up PR persists the closeout into actor state.

ChatRuntime
  - Field-level patch only: NormalizeStreamChunk now forwards
    chunk.FinishReason on the projected stream chunk (previously
    swallowed). No restructuring; ChatRuntime remains transitional.

Tests
  - 3 IConversationReplyGenerator mocks in AgentRunGAgentTests adapted
    to the new return type.
  - 5 ConversationReplyGeneratorTests reply assertions migrated to
    reply.Text.
  - New regression GenerateReplyAsync_AggregatesUsageAndFinishReasonAtActorEdge
    using UsageReportingProviderFactory mock — provider emits Usage on
    a mid-stream bookkeeping chunk and IsLast separately; the test
    asserts the actor-edge result carries both the aggregated tokens
    (7/11/18) and FinishReason ("stop").

Test state: 803 (ChannelRuntime) + 134 (Channel.Protocol) + 542 (AI)
= 1479 pass.

Subject: [PATCH 103/113] Harden ADR-0021 terminal idempotency (issue #649)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ADR-0021 §6 / canon §9 absorbing-finalized contract: late and stale
reply-chain signals must no-op once a run has reached
chain.finalized (terminal AgentRunStatus + cleanup_completed_at != 0
on the run actor; ProcessedCommandIds containment on the
conversation actor). Lifts the previously ad-hoc terminal checks
into single helpers and applies them to every handler entry.

AgentRunGAgent
  - New AgentRunGAgent.IsTerminal(status) helper (internal static for
    test access) and instance overload covering Dropped / Failed /
    ReplyHandedOff. New IsCleanupAlreadyCompleted() against
    AgentRunGAgentState.cleanup_completed_at_unix_ms.
  - HandleStartAsync uses IsTerminal at entry; only re-schedules
    cleanup when cleanup has not already completed.
  - HandleCleanupAsync uses IsTerminal at entry, then short-circuits
    on cleanup_completed_at != 0 to keep destroy idempotent. On the
    valid path it now persists AgentRunCleanupCompletedEvent before
    IActorRuntime.DestroyAsync, so the chain.finalized observable
    (cleanup_completed_at != 0) survives replay.
  - State matcher wires ApplyCleanupCompleted to write
    cleanup_completed_at_unix_ms.

ConversationGAgent
  - New IsLlmReplyTurnFinalized(correlationId) helper centralizes the
    `ProcessedCommandIds.Contains("llm:<corr>")` check.
  - HandleLlmReplyReadyAsync, HandleLlmReplyCardStreamChunkAsync, and
    HandleNyxRelayStreamingChunkCoreAsync all dedupe through the
    helper.
  - HandleDeferredLlmReplyDroppedAsync now dedupes the same way: a
    late drop notification for an already-finalized turn (run-actor
    cleanup callback fires after a successful reply already landed)
    no-ops instead of overwriting last_reply_delivery with a
    synthetic NotRetryable ConversationContinueFailedEvent.

Tests
  - Five new #649 regressions on AgentRunGAgent covering the late-
    signal classes called out in the issue:
      * Duplicate cleanup callback destroys actor once + persists
        cleanup_completed_at.
      * Cleanup for a stale RunId no-ops, leaves cleanup_completed_at
        zero.
      * Cleanup before terminal status no-ops.
      * Duplicate start after cleanup_completed does not re-schedule
        a fresh cleanup callback or re-run the LLM.
      * Duplicate start after stale-gate Drop does not re-run the
        LLM and does not persist additional drop events.

Test state: 808 ChannelRuntime + 134 Channel.Protocol + 542 AI =
1484 pass.

Issue #664 step 3b: ResponsesUserSkillsToolProvider must ctor-inject
the same singleton instances that the IAgentToolSource enumeration
returns to ChatRuntime, otherwise the two paths could diverge silently.
Switch AddSkills / AddOrnnSkills to TryAddSingleton<concrete> plus a
factory-based IAgentToolSource alias guarded against duplicate
registration, so concrete-by-type and enumerable-by-interface resolve
to one instance.

Subject: [PATCH 107/113] Bridge user skills into /v1/responses tools (issue
 #664)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

NyxID Responses 直连路径之前只把 ResponsesAevatarToolProvider 暴露的本
地工具（TodoWrite/Task/WebFetch/WebSearch）注入到 LLMRequest，没有接
入统一 skill 主干，导致 codex/Cursor 等通过 NyxID apikey 接 aevatar 的
调用方无法使用自己在 Ornn 配置的 skills。

主要改动：

- IResponsesToolProvider 改为异步并带 typed ResponsesToolProviderContext
  （caller scope + tool metadata），与未来 IAgentToolSource.DiscoverToolsAsync
  对齐；ResponsesToolClassifier.ClassifyAsync 同步重命名并按 effective
  tool name 去重 additive，避免同名工具向 LLM 重复发送，命中冲突写
  warning。
- 新增 ResponsesUserSkillsToolProvider：显式 ctor-inject
  SkillsAgentToolSource + OrnnAgentToolSource 这两个 skill 主干，桥接
  use_skill + ornn_search_skills 两个 additive 工具；不枚举
  IAgentToolSource 集合，避免后续新增的 source 被误桥接。
- Mainnet host 追加 TryAddEnumerable<IResponsesToolProvider,
  ResponsesUserSkillsToolProvider>()。
- /v1/messages 显式继续传 Array.Empty<IResponsesToolProvider>() 以保持
  Anthropic 客户端 tool harness 不被 Aevatar 工具 shadow。
- 测试：classifier 同名 additive 去重 + 异步签名；
  ResponsesUserSkillsToolProvider 只返回两个 skill 主干工具；
  /v1/responses 端到端验证桥接工具进入 LLMRequest.Tools；
  /v1/messages 回归测试验证 DI 中注册的 provider 不会注入到 Messages
  路径。后两个均通过 revert-and-rerun 验证能捕捉对应 bug。

Subject: [PATCH 108/113] Document NyxID Responses direct path and Mainnet API
 surface

- docs/canon/nyxid-responses-direct.md: new canon doc describing the
  /v1/models /v1/responses /v1/messages surface exposed via the NyxID
  proxy, OpenRouter-style <service-slug>/<model> routing, and the
  Responses caller-scope/credential contract.
- docs/canon/nyxid-llm-integration.md: cross-link Responses direct path
  and note the legacy bare-model gateway routing.
- docs/operations/2026-05-13-aevatar-responses-via-nyxid-setup.md:
  refresh the Responses-via-NyxID setup walkthrough.
- src/Aevatar.Mainnet.Host.Api/README.md: list /v1/models and
  /v1/messages alongside /v1/responses with the routing and tool-shadow
  caveats.
- docs/2026-05-14-gagent-types-analysis.md: snapshot of the current
  GAgent inheritance landscape used while scoping issue #664 follow-ups.
- docs/README.md: regenerate index for the new canon, ADR, and history
  entries that have landed.

+
+## 2. GAgent 按职责分类（Taxonomy）
+
+从上面的完整清单，按实际运行态职责可以归纳为 **6 种角色原型**：
+
+### 2.1 Catalog / Index（目录索引型）
+
+**特征**：拥有 `map<string, Entry>` 或 `repeated Entry` 的集合状态，提供 CRUD + tombstone + compact 操作。
+
+| Agent | 集合语义 |
+|---|---|
+| `ScriptCatalogGAgent` | script_name → ScriptCatalogEntry |
+| `ServiceRevisionCatalogGAgent` | service → revisions |
+| `GAgentRegistryGAgent` | agent_type + name → registry entry |
+| `RoleCatalogGAgent` | role_name → role spec |
+| `ConnectorCatalogGAgent` | connector_name → connector config |
+| `UserAgentCatalogGAgent` | user + agent_id → catalog entry |
+| `StreamingProxyParticipantGAgent` | room_id → participant set |
+| `ChatHistoryIndexGAgent` | user → conversation list |
+
+**共性模式**：`Upsert → Tombstone → Compact`，状态内维护 `last_applied_event_version`，projection 直出 current-state read model。
+
+### 2.2 Definition / Configuration（定义配置型）
+
+**特征**：持有单个 spec/record 状态，支持 bind/update/versioned lifecycle。
+
+| Agent | 持有物 |
+|---|---|
+| `WorkflowGAgent` | YAML definition + compile result |
+| `ScriptDefinitionGAgent` | Script spec + version history |
+| `ScriptBehaviorGAgent` | Definition → agent binding |
+| `ServiceDefinitionGAgent` | Service spec |
+| `ServiceConfigurationGAgent` | Service config overrides |
+| `StudioTeamGAgent` | Team definition + membership |
+| `StudioMemberGAgent` | Member profile + bindings |
+| `UserConfigGAgent` | User preferences |
+| `AevatarOAuthClientGAgent` | OAuth client spec |
+| `ExternalIdentityBindingGAgent` | External identity binding |
+| `ChannelBotRegistrationGAgent` | Bot registration per scope |
+| `ChannelUserBindingGAgent` | Channel ↔ user binding |
+| `DeviceRegistrationGAgent` | Device identity |
+
+**共性模式**：`Bind/Initialize → Update → Versioned state → current-state read model`。
+
+### 2.3 Run / Session / Execution（执行会话型）
+
+**特征**：有 `status`、`correlation_id`、`timestamps`、`input/output`，是短生命周期事实拥有者。
+
+| Agent | 运行物 |
+|---|---|
+| `WorkflowRunGAgent` | Workflow run (step execution kernel) |
+| `AgentRunGAgent` | NyxID chat run |
+| `StudioMemberBindingRunGAgent` | Member binding run |
+| `ServiceRunGAgent` | Service execution run |
+| `LlmSessionGAgent` | LLM session |
+| `SkillRunnerGAgent` | Scheduled skill execution |
+| `ConversationGAgent` | Channel conversation turn |
+
+**共性模式**：`Start → Execute → Complete/Fail → Cleanup`，状态内有明确的 status lifecycle，可能包含 nested sub-states via `map<string, Any>`。
+
+### 2.4 AI Role（AI 角色型）
+
+**特征**：继承 `RoleGAgent` 或 `AIGAgentBase`，组合 LLM + Tools + History。
+
+| Agent | 特化 |
+|---|---|
+| `RoleGAgent` | 通用角色（YAML 配置） |
+| `NyxIdChatGAgent` | NyxID 对话（继承 RoleGAgent） |
+| `ChatbotClassifierGAgent` | 分类器（继承 RoleGAgent） |
+| `ScriptGenerateGAgent` | Studio 端点（AIGAgentBase<Empty>） |
+| `WorkflowGenerateGAgent` | Studio 端点（AIGAgentBase<Empty>） |
+| `HouseholdEntity` | IoT 家户实体（AIGAgentBase） |
+
+**共性模式**：`ChatRequestEvent → ChatStreamAsync → AG-UI event publishing → tool approval lifecycle → self continuation`。
+
+### 2.5 Manager / Orchestrator（管理编排型）
+
+**特征**：协调多个子 actor 的生命周期，持有跨 actor 编排状态。
+
+| Agent | 编排物 |
+|---|---|
+| `ServiceServingSetManagerGAgent` | 服务流量集分配 |
+| `ServiceDeploymentManagerGAgent` | 服务部署进度 |
+| `ServiceRolloutManagerGAgent` | 服务灰度发布进度 |
+| `ScriptEvolutionManagerGAgent` | 脚本演化 session 调度 |
+| `ScriptEvolutionSessionGAgent` | 单次演化会话推进 |
+| `TaskBoardGAgent` | 任务板（claim/complete） |
+| `TeamManagerGAgent` | 团队成员注册与广播 |
+| `StreamingProxyGAgent` | 流式房间管理（topic broadcast） |
+| `ResponsesAgentToolStateGAgent` | Agent 工具状态追踪 |
+
+**共性模式**：持有 child-reference 列表、progress tracking、completion aggregation。
+
+### 2.6 Bridge / Adapter（桥接适配型）
+
+**特征**：无状态或极轻状态，在 Actor 系统与外部系统之间做协议转换。
+
+| Agent | 桥接物 |
+|---|---|
+| `TelegramBridgeGAgent` | Telegram API ↔ Actor |
+| `TelegramUserBridgeGAgent` | Telegram user ↔ Agent user |
+| `UserMemoryGAgent` | User memory store |
+| `ChatConversationGAgent` | Chat conversation store |
+
+---
+
+## 3. 底座能力评估：GAgent 是否胜任当前 Harness 工程？
+
+### 3.1 底座已提供的能力
+
+| 能力 | 来源 | 评价 |
+|---|---|---|
+| 统一事件管线 | `GAgentBase.HandleEventAsync` | ✅ 成熟。静态 + 动态模块管线、Hook 双通道、pipeline cache |
+| Event Sourcing | `GAgentBase<TState>` | ✅ 成熟。Replay + Commit + Snapshot + OCC absorption |
+| 配置合并 | `GAgentBase<TState, TConfig>` | ✅ 通用。class defaults + state overrides |
+| AI 能力组合 | `AIGAgentBase<TState>` | ✅ 内聚。ChatRuntime + ToolManager + History + Hooks + Middleware |
+| 消息发布 | `PublishAsync / SendToAsync` | ✅ 清晰。Topology 路由 + Direct 路由 |
+| Durable Callback | `ScheduleSelfDurableTimeoutAsync / TimerAsync` | ✅ 已事件化 |
+| External Links | `IExternalLinkAware + ExternalLinkManager` | ✅ 插件式 |
+| Projection 编排 | `ProjectionScopeGAgentBase` 系列 | ✅ Actor 化，符合 AGENTS.md 约束 |
+| Runtime 可替换 | `LocalActorRuntime / OrleansActorRuntime` | ✅ runtime-neutral 抽象 |
+
+### 3.2 底座当前的不适配点
+
+#### 3.2.1 Agent Loop = Agent Continuation 的缺失
+
+当前系统中的 "agent loop"（LLM tool calling 循环、workflow step 推进循环、对话 turn 循环）**没有统一抽象为 agent 间消息传递**。
+
+现状：
+- `ToolCallLoop.ExecuteAsync` 是 **进程内同步循环**，在单个 actor turn 内跑完全部 tool rounds
+- `WorkflowExecutionKernel` 是 **EventModule 内部循环**，通过模块内部状态机推进
+- `ConversationGAgent` 的 turn runner 是 **durable callback + 自事件** 模式（最接近理想态）
+
+理想态（AGENTS.md "agent continuation" 语义）：
+```
+Agent A 执行一步 → 发布 intermediate event → Agent B（或 A 自身）消费 → 发布 next event → ...
+```
+
+**差距**：底层基础设施（EventEnvelope、PublishAsync、SendToAsync、Durable Callback）已完全支持 agent continuation，但上层缺少一个 **continuation protocol** 来把 "loop" 声明式地建模为 agent 间消息传递。ToolCallLoop 和 WorkflowExecutionKernel 各自内部实现了循环，没有复用同一套 continuation 抽象。
+
+#### 3.2.2 Run / Session 型 Agent 缺乏统一基类
+
+当前所有 Run/Session 型 GAgent 都直接继承 `GAgentBase<TState>`，各自重新实现：
+- Status lifecycle（start → running → completed/failed）
+- Input/Output binding
+- Timeout and cleanup
+- Correlation tracking
+- Completion event publishing
+
+`AgentRunGAgent`、`WorkflowRunGAgent`、`StudioMemberBindingRunGAgent`、`ServiceRunGAgent`、`SkillRunnerGAgent` 都有高度相似的状态结构，但没有任何共享抽象。
+
+#### 3.2.3 Catalog 型 Agent 缺乏通用 CatalogGAgent
+
+所有 Catalog/Index 型 Agent 重复实现：
+- `map<string, Entry>` 状态
+- Upsert/Tombstone/Compact 事件
+- `last_applied_event_version` 追踪
+- Current-state read model projection
+
+没有 `CatalogGAgentBase<TKey, TEntry>` 这样的通用基类。
+
+#### 3.2.4 Streaming / Continuation 的半成品
+
+`TurnStreamingReplySink` 和 `NyxIdChatStreamingRunner` 各自实现了 streaming → actor → SSE 的半链路，但没有统一的 "streaming continuation" 抽象把 LLM 流式输出、actor 间传递、SSE/WS 推送串成一条声明式管道。
+
+---
+
+## 4. 类型精简分析：GAgent Types 能否进一步抽象？
+
+### 4.1 潜在的通用基类
+
+#### 4.1.1 `RunGAgentBase<TState>` — 执行会话基类
+
+**适用对象**：`AgentRunGAgent`、`WorkflowRunGAgent`、`StudioMemberBindingRunGAgent`、`ServiceRunGAgent`、`SkillRunnerGAgent`
+
+**可抽取的通用能力**：
+```
+abstract class RunGAgentBase<TState> : GAgentBase<TState>
+  where TState : class, IMessage<TState>, new()
+{
+  // 通用 status lifecycle
+  protected abstract string Status { get; }     // running/completed/failed/stopped
+  protected abstract string RunId { get; }
+  
+  // 通用 completion publishing
+  protected Task PublishRunCompletedAsync(...);
+  protected Task PublishRunFailedAsync(...);
+  
+  // 通用 cleanup (via durable callback)
+  protected Task ScheduleCleanupAsync(TimeSpan delay);
+  
+  // 通用 stale-input detection
+  protected bool IsStaleRun(string expectedRunId);
+}
+```
+
+**预估影响**：5 个 Run 型 GAgent 可共享生命周期管理代码，减少 ~30% 重复逻辑。
+
+#### 4.1.2 `CatalogGAgentBase<TState, TKey, TEntry>` — 目录索引基类
+
+**适用对象**：`ScriptCatalogGAgent`、`GAgentRegistryGAgent`、`RoleCatalogGAgent`、`ConnectorCatalogGAgent`、`UserAgentCatalogGAgent`、`StreamingProxyParticipantGAgent`、`ChatHistoryIndexGAgent`
+
+**可抽取的通用能力**：
+```
+abstract class CatalogGAgentBase<TState> : GAgentBase<TState>
+  where TState : class, IMessage<TState>, new()
+{
+  // 通用 upsert/tombstone/compact 事件处理
+  // 通用 last_applied_event_version 追踪
+  // 通用 current-state read model 投影契约
+}
+```
+
+**预估影响**：7 个 Catalog 型 GAgent 可共享 CRUD + projection 逻辑。
+
+#### 4.1.3 Agent Continuation Protocol — 不新增 GAgent type，而是新增行为协议
+
+**关键洞察**：Agent continuation 不需要新的 GAgent 基类，而是需要一套 **消息协议** 把 "loop" 建模为 agent 间消息传递。
+
+**建议的 Continuation 协议**：
+```protobuf
+// 一个 continuation step 完成后，发布此事件请求下一步
+message ContinueRequested {
+  string continuation_id = 1;    // 会话标识
+  string step_type = 2;          // 当前步骤类型
+  google.protobuf.Any step_result = 3;  // 步骤结果
+  google.protobuf.Any step_context = 4; // 步骤上下文（传递到下一步）
+}
+
+// continuation 完成或失败
+message ContinuationCompleted { ... }
+message ContinuationFailed { ... }
+```
+
+**适用范围**：
+- ToolCallLoop → 改为：RoleGAgent 每轮 tool call 结束后发布 `ContinueRequested` → 自身消费 → 下一轮
+- WorkflowExecutionKernel → 改为：WorkflowRunGAgent 每步结束后发布 `ContinueRequested` → 自身消费 → 下一步
+- ConversationGAgent turn runner → 已接近此模式
+
+**好处**：
+1. 每个 "loop iteration" 变成一次 actor turn，天然可观测、可恢复
+2. 中间状态通过 `step_context` 在事件链中传递，不再依赖进程内变量
+3. 天然适配 streaming：每个 continuation step 可以发布 streaming chunk
+4. 可与现有 `ScheduleSelfDurableTimeoutAsync` 结合，实现 timeout-based continuation
+
+### 4.2 不建议合并的 Types
+
+以下 GAgent 虽然可能有表面相似性，但 **业务语义足够独立**，不建议强行合并：
+
+| GAgent | 不合并原因 |
+|---|---|
+| `ConversationGAgent` | 渠道特化的 turn runner（Lark streaming、NyxRelay）逻辑复杂且不可通用 |
+| `StreamingProxyGAgent` | topic/message broadcast 语义与 Catalog/Run 都不同 |
+| `ServiceRolloutManagerGAgent` | 灰度发布是专用 domain，state machine 复杂 |
+| `ScriptEvolutionSessionGAgent` | 演化 session 的 propose/promote/rollback 有专用状态机 |
+
+### 4.3 精简路径总结
+
+| 动作 | 影响 | 复杂度 |
+|---|---|---|
+| 引入 `RunGAgentBase<TState>` | 5 个 GAgent 共享生命周期 | 中 |
+| 引入 `CatalogGAgentBase<TState>` | 7 个 GAgent 共享 CRUD + projection | 中 |
+| 引入 Continuation Protocol | ToolCallLoop + WorkflowKernel 统一为消息传递 | 高 |
+| 保持现状 | 零风险，但重复度持续累积 | — |
+
+---
+
+## 5. Agent Continuation 深度分析
+
+### 5.1 为什么 Agent Loop 应该实现为 Agent Continuation
+
+当前代码中的三种 "loop" 实现方式：
+
+| Loop 类型 | 当前实现 | 问题 |
+|---|---|---|
+| LLM Tool Calling Loop | `ToolCallLoop.ExecuteAsync` — 进程内 `while` 循环 | 1. 整个 loop 在单次 actor turn 内完成，无法被外部观察 2. 中间 tool call 状态不在 event store 中 3. 无法跨节点恢复 |
+| Workflow Step Loop | `WorkflowExecutionKernel` — EventModule 内部推进 | 1. 模块内部状态机不经过 actor event pipeline 2. 模块状态通过 `map<string, Any>` 持久化，但不产出独立 domain event 3. 可观测性受限 |
+| Conversation Turn Loop | `ConversationGAgent` + durable callback + self-event | ✅ 最接近理想态。每轮 turn 都是独立 event，可恢复、可观测 |
+
+**核心论点**：Agent continuation 不是 "更好的 loop"，而是 **把 loop 的每一步都变成可观测、可恢复、可跨节点的事实**。
+
+### 5.2 Continuation 与现有机制的配合
+
+```
+                     ┌─────────────────────┐
+                     │   GAgentBase         │

+          │ Stream  │ │ Domain   │ │ Durable     │
+          │ Chunk   │ │ Event    │ │ Timeout     │
+          └─────────┘ └────┬─────┘ └──┬──────────┘
+                          │           │
+                          │    ┌──────▼──────────┐
+                          │    │ Self-Continue    │
+                          │    │ (timeout or      │
+                          │    │  completion)     │
+                          │    └──────┬──────────┘
+                          │           │
+                          └─────► Next Turn
+```
+
+这个模型完全在现有 `GAgentBase` 的能力范围内：
+- `PublishAsync` → streaming chunks
+- `PersistDomainEventAsync` → 事实持久化
+- `ScheduleSelfDurableTimeoutAsync` → timeout-based continuation
+- `SendToAsync(Id, continueEvent)` → self continuation
+
+**不需要新的 GAgent 基类，只需要一套 continuation 消息协议 + 推荐模式。**
+
+### 5.3 从 ToolCallLoop 到 Agent Continuation 的演进路径
+
+**当前**：
+```csharp
+// ToolCallLoop.ExecuteAsync — 进程内循环
+while (rounds < maxRounds) {
+    var response = await CallLLMAsync(...);
+    if (no tool calls) return response;
+    var results = await ExecuteToolCallsAsync(...);
+    history.AddToolResults(results);
+    rounds++;
+}
+```
+
+**目标态**：
+```csharp
+// RoleGAgent.HandleContinueRequested — 每个 continuation step 是一个 actor turn
+[EventHandler(AllowSelfHandling = true)]
+public async Task HandleContinueRequested(ContinueRequested evt)
+{
+    // 1. 从 step_context 恢复当前轮次状态
+    // 2. 调用 LLM (streaming，每个 chunk 通过 PublishAsync 发布)
+    // 3. 如果有 tool calls → 执行 → Persist tool results → SendToAsync(Self, next ContinueRequested)
+    // 4. 如果没有 tool calls → Persist final response → Publish ContinuationCompleted
+}
+```
+
+**代价**：每个 tool call round 变成一次完整的 actor turn（event store write + commit），延迟略增。
+**收益**：每步可观测、可恢复、可跨节点、可被 hook 拦截。
+
+### 5.4 WorkflowExecutionKernel 的 Continuation 化
+
+Workflow 实际上已经部分 continuation 化了（`WorkflowRunGAgent` 的步骤推进），但步骤内部状态（`ExecutionStates` map）的变更不经过 `PersistDomainEventAsync`。如果引入 continuation 协议：
+
+- 每个步骤完成 → `PersistDomainEventAsync(StepCompletedEvent)` → `PublishAsync(ContinueRequested)`
+- 模块状态变更 → 独立 domain event（而非 `map<string, Any>` 的批量覆盖）
+- 中间结果 → 可被 projection 直接消费
+
+---
+
+## 6. 结论与建议
+
+### 6.1 底座评价
+
+**GAgent 底座能力是合格的**。它提供了：
+- 完整的事件管线、Event Sourcing、配置合并
+- Runtime-neutral 的创建/调度/发布抽象
+- AI 能力组合（LLM + Tools + Hooks）
+- Durable callback（timeout/timer）
+- Projection 编排
+
+**不存在需要重写底座的理由**。
+
+### 6.2 需要补充的是上层协议和模式，而非底层重构
+
+| 优先级 | 建议 | 理由 |
+|---|---|---|
+| P0 | 定义 **Continuation Protocol**（消息协议，不是新基类） | 把 agent loop 统一为可观测的消息传递，这是架构层面最大的缺失 |
+| P1 | 引入 `RunGAgentBase<TState>` | 5 个 Run 型 GAgent 的 status lifecycle 高度重复 |
+| P2 | 引入 `CatalogGAgentBase<TState>` | 7 个 Catalog 型 GAgent 的 CRUD 模式高度重复 |
+| P3 | Streaming Continuation 管道统一 | 把 `TurnStreamingReplySink` 和 `NyxIdChatStreamingRunner` 统一为 continuation protocol 的一部分 |
+
+### 6.3 不建议做的事
+
+- ❌ 不建议把所有 GAgent 合并成少数几个 "万能" 类型（业务语义差异太大）
+- ❌ 不建议为 continuation 新增 GAgent 基类（现有 `GAgentBase` + continuation protocol 已足够）
+- ❌ 不建议在 Foundation 层做 AI/workflow 特化（保持 Foundation 通用，特化在 AI/Workflow 层）
+- ❌ 不建议一步到位把 ToolCallLoop 改成 continuation（渐进式：先在 RoleGAgent 加 continuation 入口，ToolCallLoop 作为 fast path 并存）

+
+# NyxID Responses 直连
+
+本文说明外部客户端如何通过 NyxID proxy 直连 Aevatar 的 OpenAI Responses 兼容接口，以及当前已经上线的 Anthropic Messages 窄门面。
+
+这里的“直连”不是绕过 NyxID 直接访问 Aevatar。客户端只认 NyxID proxy，Aevatar 只接收 NyxID 转发过来的 bearer 身份，再用同一把调用者凭据经 NyxID 访问下游 LLM 服务。
+
+## 1. 范围与状态
+
+当前对外入口有四个：
+
+| 入口 | 协议形态 | 状态 | 说明 |
+|---|---|---|---|
+| `GET /v1/models` | OpenAI models list | 已上线 | 聚合调用者在 NyxID 上可达的 LLM 服务模型 |
+| `POST /v1/responses` | OpenAI Responses 兼容 | 已上线 | 主入口，支持 streaming、工具声明、`previous_response_id` continuation |
+| `POST /v1/responses/{id}/cancel` | OpenAI Responses cancel | 已上线 | 取消可见的 response session |
+| `POST /v1/messages` | Anthropic Messages facade | 已上线 | 给 Claude Code 这类 Messages-only 客户端使用，能力刻意做窄 |
+
+推荐外部客户端统一走：
+
+```text
+https://nyx-api.chrono-ai.fun/api/v1/proxy/s/aevatar/v1/...
+```
+
+不要把客户端配置成 Aevatar Host 的真实域名。NyxID proxy 负责校验 API key、服务授权、凭据注入和审计；绕过它会导致 Aevatar 无法解析调用者身份。
+
+## 2. 鉴权与 Caller Scope
+
+所有 `/v1/*` 入口都要求：
+
+```http
+Authorization: Bearer nyx_...
+```
+
+Aevatar endpoint 本身标记为 anonymous，不是因为免鉴权，而是因为 NyxID API key 是 opaque token，不是 Host 的 JWT。handler 会手动取出 bearer token，并通过 NyxID 当前用户接口解析调用者。
+
+解析结果会落到 Responses caller scope：
+
+- `scopeId`：NyxID user id
+- `ownerSubject`：NyxID user id
+- `origin kind`：`ApiKey`
+
+后续 response session 可见性、工具状态、模型路由、下游 LLM 调用都基于这个 caller scope。`commandId/correlationId` 只用于追踪，不承担用户身份语义。
+
+## 3. 模型清单与路由
+
+`GET /v1/models` 会从 NyxID LLM service catalog 取到调用者可见的服务，再 fan-out 到每个服务的 `/models` 平面。Aevatar 返回给客户端的模型 id 统一带服务前缀：
+
+```text
+<service-slug>/<model-id>
+```
+
+例如：
+
+```text
+chrono-llm/gpt-5.5
+llm-anthropic/claude-haiku-4-5
+```
+
+每个 model entry 还会尽量带上：
+
+- `route_value`：NyxID 真实 route，例如 `/api/v1/proxy/s/chrono-llm`
+- `group` / `owned_by`：服务 slug
+- `context_length`
+- `max_output_tokens`
+- `display_name`
+- `description`
+
+发起 `/v1/responses` 或 `/v1/messages` 时，客户端应该优先使用 `/v1/models` 返回的完整 id。Aevatar 会解析 `<service-slug>/<model>`：
+
+1. 如果 prefix 像 NyxID service slug，并能在调用者 catalog 中解析到 route，Aevatar 会把 route 写入 `NyxIdRoutePreference`，再把裸 model 传给下游 provider。
+2. 如果 prefix 解析不到，或模型名本来就是裸模型名，Aevatar 走默认 gateway fallback，让 NyxID gateway 自己按 model 名处理。
+
+裸模型名仍然保留是为了兼容旧调用方；新客户端不要依赖裸名自动路由。
+
+## 4. Responses 主入口
+
+`POST /v1/responses` 是当前推荐的主入口。它支持：
+
+- JSON 与 SSE streaming 两种返回形态
+- OpenAI Responses 风格的 `input`
+- `tools` 声明
+- `function_call_output`
+- `previous_response_id`
+- `max_output_tokens`、`temperature`
+- response session 注册、查询可见性校验、24 小时 TTL
+
+`previous_response_id` 的约束是诚实的：只能继续同一 caller scope 可见、未过期、未失败、未取消的 session。带 `function_call_output` 且显式带 `previous_response_id` 时，Aevatar 会按上一轮记录的 forwarded tool call 对账。
+
+为了兼容 Anthropic 到 OpenAI 的转换器，如果请求里有 `function_call_output`，但没有 `previous_response_id`，Aevatar 不会直接报错，而是把这些 tool result 折进 prompt，形如：
+
+```text
+[tool_result call_id=...] ...
+```
+
+这只是兼容无状态客户端的历史上下文折叠，不等于正式 continuation。
+
+## 5. Responses 工具行为
+
+`/v1/responses` 会把客户端声明的工具分成两类：
+
+- Aevatar substitute tools：由服务端接管执行并记录状态。
+- forwarded tools：保留给客户端或上游模型继续处理。
+
+当前 substitute tools 包括：
+
+| 工具名 | 说明 |
+|---|---|
+| `TodoWrite` | 持久化 agent-scoped todo state |
+| `Task` / `task` | 记录 sub-agent task topology trace |
+| `WebFetch` / `web_fetch` | 通过 Aevatar 抓取 URL，记录 trace/cache |
+| `WebSearch` / `web_search` | 通过 Aevatar 执行 web search，记录 trace/cache |
+
+注意：这些是 Responses 边界内的本地替代工具。仓库里的 Ornn 用户技能目前还没有桥接到 `/v1/responses` 的工具列表；不要把 `use_skill`、`ornn_search_skills` 写成已经可用的 Responses 能力。这个缺口对应 issue #664 的后续工作。
+
+## 6. Messages 窄门面
+
+`POST /v1/messages` 已经上线，但它不是 `/v1/responses` 的完整替代品。它的定位是让只会说 Anthropic Messages 的客户端，例如 Claude Code，能通过同一条 NyxID proxy 链路访问 Aevatar。
+
+当前行为：
+
+- 每个请求注册一个新的 `LlmSession`。

+## 7. API Key 要求
+
+NyxID slug proxy 路由是 REST proxy plane：
+
+```text
+/api/v1/proxy/s/{slug}/{path}
+```
+
+因此 API key 至少需要 `proxy` scope，或更宽的 proxy scope。生产上可以用 `--allowed-services` 收紧到 Aevatar 与目标 LLM 服务；调试时可以先用 `--allow-all-services` 验证链路。
+
+`--allowed-services` 必须填 `nyxid service list --output json` 里的 UserService id，不是 catalog id。填错时常见错误是 `api_key_scope_forbidden_legacy`。

 - `Authorization: Bearer <token>` 只在请求上下文中透传，不会落盘；持久化的 response session 只记录 NyxID `/me` 解析出的 caller scope 与 opaque `response.id`。
 - forward tool call 在输出给客户端前会先落 response session actor，记录 `call_id`、`tool_name`、`schema_hash`、arguments、状态与过期时间。客户端续传 tool result 时可携带 `schema_hash`，不匹配会返回明确 4xx。
 - `Task`、`Todo*`、`WebFetch`、`WebSearch` 属于 substitute 类，会在 `/v1/responses` boundary 被替换为 Aevatar tool；其他客户端 declared tools 默认 forward。`aevatar_*` additive tool 接口已预留。
 - substitute 工具状态归 `ResponsesAgentToolStateGAgent` 拥有：`TodoWrite` 写入 agent-scoped todo state，`Task` 记录可投影的 topology trace，`WebFetch` / `WebSearch` 记录 trace 与简单 cache 命中状态；这些状态通过 ProjectionPipeline 物化为 current-state read model，可供后续会话查询。
 - cancel 端点会复用同一 bearer token scope resolution；可见性通过后，session actor 会把 response 标记为 `cancelled` 并将 pending forwarded tool call 标为 `cancelled`。已过期或已取消的 `previous_response_id` 不能 resume。
+- `/v1/messages` 是 Anthropic Messages 窄门面。它每次请求注册一个新的 `LlmSession`，不支持 `previous_response_id`，`max_tokens` 必填，不注入 Aevatar substitute tools；`top_p`、`top_k`、`stop_sequences` 和 forced `tool_choice` 会被拒绝，image content v1 会被丢弃并记录 warning。

Subject: [PATCH 110/113] Suppress duplicate AgentRunDispatcher dispatches and
 clean up on enqueue failure

ADR-0021 defines DispatchPhase.RejectedDuplicate but the dispatcher
previously did a "GetAsync ?? CreateAsync" that silently re-enqueued
start commands for a runId whose actor already existed. The envelope
also used Guid.NewGuid() for the command id, so the run actor inbox
had no envelope-level idempotency to fall back on.

Changes:

- Serialize dispatch under a SemaphoreSlim and reject when
  IActorRuntime.ExistsAsync(actorId) is true; outcome carries
  RejectedDuplicate + the existing actorId.
- Build a deterministic commandId ("agent-run-start:{runId}") and put
  it on EventEnvelope.Runtime.Deduplication.OperationId so the inbox
  has a stable dedup key if the dispatcher boundary is ever bypassed.
- If ProduceAsync fails after CreateAsync succeeded, destroy the
  freshly created run actor so a retry can re-create instead of
  bouncing on RejectedDuplicate.
- Tests: parallel WhenAll dispatch returns exactly one Accepted + one
  RejectedDuplicate with the existing inbox unchanged; enqueue failure
  destroys the actor and a follow-up dispatch is accepted; stale
  request never reaches CreateAsync.

shipped behavior:

  (substitute / additive / forwarded), name use_skill +
  ornn_search_skills as the live additive set, and call out that they
  walk through NyxID proxy under the caller's bearer (so a restricted
  NyxID API key must keep the Ornn API service in --allowed-services).
- operations/2026-05-13-aevatar-responses-via-nyxid-setup.md: note that
  the bridge is /v1/responses-only, mention the Ornn-service allowlist
  step in the codex/Responses configuration block, refresh the
  Messages-client notes, and replace the "Ornn 还没桥接" troubleshooting
  row with bridge-aware ones.
- src/Aevatar.Mainnet.Host.Api/README.md: replace the aevatar_*
  placeholder line with use_skill / ornn_search_skills additives and
  spell out that /v1/messages does NOT inject them.
