+```
+
+## Running tests
+

+# Unit tests (no LLM keys needed)
+tests/run_tests.sh unit
+
+# Smoke tests (needs LLM API key in env)
+tests/run_tests.sh smoke

+
+## Coding style
+
+Full rules live in `docs/simple-coding-rules.md`. The short version:
+
+- **Minimal code.** Prefer fewer functions, fewer layers, fewer lines.
+- **Strict schemas.** Use Pydantic models / enums for inputs and outputs.
+- **Fail fast.** No `try/except` fallbacks for missing packages. If something
+  is required, let it raise.
+- **Docstrings everywhere.** Every file gets a top-level docstring explaining
+  what it contains. Every function gets a docstring.
+- **Self-tests.** Add an `if __name__ == "__main__":` block that exercises the
+  real code path (no mocking or stubbing). Keep it inline, not in a separate
+  function.
+- **No dead code.** When you replace logic, remove the old path.
+- **Config from TOML, keys from env.** Runtime config comes from the TOML
+  layer stack (`default.toml -> global -> project -> env var`). Only API keys
+  use environment variables.
+
+## Adding a new platform adapter
+
+This is the most common contribution. Follow these steps:
+
+1. **Create `src/lerim/adapters/<platform>.py`.**
+   Start with a top-level docstring. Implement the four functions required by
+   the `Adapter` protocol in `src/lerim/adapters/base.py`:
+
+   - `default_path() -> Path | None` -- where traces live on disk.
+   - `count_sessions(path) -> int`
+   - `iter_sessions(traces_dir, start, end, known_run_ids) -> list[SessionRecord]`
+   - `find_session_path(session_id, traces_dir) -> Path | None`
+   - `read_session(session_path, session_id) -> ViewerSession | None`
+
+   See an existing adapter (e.g. `codex.py` or `claude.py`) as a reference.
+
+2. **Register the adapter** in `src/lerim/adapters/registry.py`:
+   add an entry to `_ADAPTER_MODULES` and optionally to `_AUTO_SEED_PLATFORMS`.
+
+3. **Add a self-test** (`if __name__ == "__main__":` block) at the bottom of
+   the new adapter file that exercises the real code path.
+
+4. **Add unit tests** in `tests/test_<platform>_adapter.py`. Look at the
+   existing adapter test files for the expected patterns.
+
+5. **Update `tests/README.md`** if you added new fixtures or test infrastructure.
+
+## Reporting bugs
+
+Open a GitHub issue with:
+
+- Steps to reproduce.
+- Expected vs actual behavior.
+- Lerim version (`python -m lerim --version`), Python version, and OS.
+- Relevant config (redact API keys).
+
+## Pull request checklist
+
+- [ ] `ruff check src/ tests/` passes with no errors.
+- [ ] `tests/run_tests.sh unit` passes.
+- [ ] New/changed files have top-level docstrings and function docstrings.
+- [ ] New source files include an `if __name__ == "__main__":` self-test when practical.
+- [ ] No mocking or stubbing in self-test flows.
+- [ ] Related docs updated if behavior changed.

 Lerim is a continual learning layer that gives coding agents persistent memory across sessions. It watches your agent conversations (Claude Code, Codex, Cursor, OpenCode, ...), extracts decisions and learnings, and stores them as plain markdown files that both humans and agents can read. Memories are refined offline over time through merging, deduplication, archiving, and decay-based forgetting. You can query stored memories anytime to bring relevant past context into your current session.

+### Tabs
+
+- **Overview**: high-level metrics and charts (sessions, messages, tools, errors, tokens, activity by day/hour, model usage).
+- **Runs**: searchable session list (50/page) with status and metadata; open any run in a full-screen chat viewer.
+- **Memories**: library + editor for memory records (filter, inspect, edit title/body/kind/confidence/tags).
+- **Pipeline**: sync/maintain status, extraction queue state, and latest extraction report.
+- **Settings**: dashboard-editable config for server, model roles, and tracing; saves to `~/.lerim/config.toml`.

+### Notes
+
+- Top bar filters (`Agent`, `Scope`) update dashboard metrics and run listings.
+- Graph Explorer code is kept in the project but currently hidden in the UI.

-### Supported platforms
+### Connecting coding agents
 
-- `claude` — reads from `~/.claude/projects/` (JSONL files)
-- `codex` — reads from `~/.codex/sessions/` (JSONL files)
-- `cursor` — reads from Cursor's `state.vscdb` SQLite DB, exports sessions as JSONL to `~/.lerim/cache/cursor/`
-- `opencode` — reads from `~/.local/share/opencode/`
+Lerim ingests session transcripts from your coding agents to extract decisions and learnings. The `lerim connect` command registers an agent platform so Lerim knows where to find its sessions.
+
+#### Supported agents
+
+| Platform | Session store | Format |
+|----------|--------------|--------|
+| `claude` | `~/.claude/projects/` | JSONL files |
+| `codex` | `~/.codex/sessions/` | JSONL files |
+| `cursor` | `~/Library/Application Support/Cursor/User/globalStorage/` (macOS) | SQLite `state.vscdb`, exported to JSONL cache |
+| `opencode` | `~/.local/share/opencode/` | SQLite `opencode.db`, exported to JSONL cache |
+
+#### How to connect
+
+Auto-detect and connect all supported platforms at once:
+
+```bash
+lerim connect auto
+```
+
+Or connect a specific platform:
+
+```bash
+lerim connect claude
+lerim connect codex
+lerim connect cursor
+lerim connect opencode
+```
+
+List currently connected platforms:
+
+```bash
+lerim connect list
+```
+
+Disconnect a platform:
+
+```bash
+lerim connect remove claude
+```
+
+#### Custom session path
+
+If your agent stores sessions in a non-default location, use `--path` to point Lerim to the correct folder:
+
+```bash
+lerim connect claude --path /custom/path/to/claude/sessions
+lerim connect cursor --path ~/my-cursor-data/globalStorage
+```
+
+The path is expanded (`~` is resolved) and must exist on disk. This overrides the auto-detected default for that platform.

-    Transcript format: JSONL (one JSON object per line, newline-separated).
-    Parse by splitting on newlines and parsing each line as JSON.
-
-    Example formats from different coding agents (actual keys may vary):
-    1) Simple: {"role": "user", "content": "I decided to use X instead of Y", "timestamp": "2026-02-23T10:00:00Z"}

-    3) Codex: {"type": "event_msg", "payload": {"type": "user_message", "message": "Lesson:..."}}
-
-    Note: Different agents use different key names. Look for common patterns like
-    user/assistant role indicators, content/text/message fields, and timestamp info.
-
-    Primitive type rules (must be consistent):
-    - decision: an explicit choice, preference, or configuration that should stay stable.
-      Trigger words: "decision", "we will", "use X not Y", "always do", "never do", "set X to Y".
-    - learning: a lesson, fix, pattern, or friction signal learned from experience.
-      Trigger words: "lesson", "fix", "found that", "struggled with", "wasted time on".
-    - When in doubt, prefer learning. Only use decision when the transcript contains
-      a clear deliberate choice or a stated configuration value.
+    IMPORTANT -- Extraction strategy (you are running inside an RLM REPL):
+    1) Do NOT normalize or pre-parse the transcript schema. Treat it as raw text.
+       Different agents (Claude Code, Codex, Cursor, Windsurf) use different JSON shapes.
+    2) First EXPLORE: sample a few spans from beginning, middle, and end to understand
+       the structure and length. Print samples, check types. Do not try to solve in one step.
+    3) Build overlapping windows of ~20,000 characters with ~2,000 overlap.
+    4) For each window, use llm_query() to extract only durable, high-value items:
+       - decision: explicit stable choice / configuration / policy.
+         Trigger words: "decision", "we will", "use X not Y", "always do", "never do", "set X to Y".
+       - learning: reusable lesson / fix / pitfall / friction signal / user preference / habit.
+         Trigger words: "lesson", "fix", "found that", "struggled with", "wasted time on",
+         "I prefer", "I like", "I want", "I always", "my style", "don't like", "hate when",
+         "keep it", "make sure", "never use", "always use", "I usually", "my convention".
+       - When in doubt, prefer learning.
+    5) For every extracted item, keep one short verbatim evidence quote (<=200 chars).
+    6) After processing all windows, MERGE near-duplicates across windows.
+    7) Prefer precision over recall. If evidence is weak, drop it.
+    8) SUBMIT only the final deduplicated primitives list.
 
     Kind (for learnings only):
     - insight: a reusable observation or pattern.
     - procedure: a step-by-step fix or workflow.
     - friction: a blocker, struggle, or time-waster.
     - pitfall: a mistake to avoid.
-    - preference: a soft preference (not a hard decision).
+    - preference: a user preference, habit, convention, or style choice.
+      Examples: coding style, tool choices, naming conventions, communication preferences,
+      workflow habits, formatting rules, library preferences.

-    Examples: queue, heartbeat, docker, ci-cd, patching, error-handling.

+       - user goals and intentions

+       - fixes applied and outcomes achieved

+
+# Smoke tests (requires LLM — default: openrouter, ~80s)
+tests/run_tests.sh smoke

+```
+
+The test runner auto-activates `.venv` if not already active and `cd`s to the project root.
+Override the test LLM provider/model via env vars `LERIM_TEST_PROVIDER` and `LERIM_TEST_MODEL`, or via `tests/test_config.toml`.
+Default provider: `openrouter/qwen/qwen3-coder-30b-a3b-instruct` for all roles.
+
+## Test Categories
+
+### Unit (`pytest -m "not integration and not e2e and not smoke"`)
+

+
+Full CLI command flows as a user would invoke them. Requires working LLM.
+
+| File | What it tests |
+|------|---------------|
+| `test_e2e_sync.py` | `lerim sync` against fixture traces creates memories; re-running is idempotent (no duplicates) |
+| `test_e2e_maintain.py` | `lerim maintain` on seeded memories performs maintenance actions (archival, dedup) |

+
+## Regression / Contract Tests
+
+Regression tests live in unit-land (no LLM needed) but serve a distinct purpose: they pin down public API surfaces so accidental breakage is caught immediately. If a field is added or removed from a Pydantic model, or a CLI subcommand is renamed, these tests fail.
+
+`test_regression_contracts.py` checks:
+
+- **`SyncResultContract`** — exact field set (`trace_path`, `memory_root`, `workspace_root`, `run_folder`, `artifacts`, `counts`, `written_memory_paths`, `summary_path`)
+- **`MaintainResultContract`** — exact field set (`memory_root`, `workspace_root`, `run_folder`, `artifacts`, `counts`)
+- **`SyncCounts`** — fields: `add`, `update`, `no_op`
+- **`MaintainCounts`** — fields: `merged`, `archived`, `consolidated`, `decayed`, `unchanged`
+- **`MemoryCandidate`** — fields: `primitive`, `kind`, `title`, `body`, `confidence`, `tags`
+- **CLI subcommands** — `connect`, `sync`, `maintain`, `daemon`, `chat`, `memory`, `dashboard`, `status` all present
+- **`MEMORY_FRONTMATTER_SCHEMA`** — decision and learning types have expected keys (`id`, `kind`, etc.)
+
+When changing any of these contracts, update the corresponding test assertions. These are intentionally strict — a diff in fields means the contract changed and downstream consumers may break.
+
+## Fixture Dataset
+
+Hand-crafted fixture files live in `tests/fixtures/`. These are NOT auto-generated — they are minimal, deterministic inputs designed for specific test scenarios.
+
+### Trace fixtures (`fixtures/traces/`)
+
+| File | Lines | Format | Purpose |
+|------|-------|--------|---------|
+| `claude_simple.jsonl` | 6 | Claude (`type`/`message`) | JWT auth decision + CORS learning; primary happy-path trace |
+| `claude_long_multitopic.jsonl` | ~20 | Claude | Long multi-topic session; tests windowed extraction |
+| `codex_simple.jsonl` | varies | Codex | Codex adapter parsing verification |
+| `codex_with_tools.jsonl` | varies | Codex | Codex trace with tool calls; tests tool-call extraction |
+| `debug_session.jsonl` | ~10 | Generic | Debugging session; tests friction/pitfall extraction |
+| `mixed_decisions_learnings.jsonl` | 8 | Generic (`role`/`content`) | Multiple decisions AND learnings in one trace; tests extraction of mixed primitives |
+| `edge_short.jsonl` | 2 | Generic | Minimal conversation; edge case for very short input |
+| `edge_empty.jsonl` | 2 | Generic | Empty user content; edge case for noise/empty input handling |
+
+### Memory fixtures (`fixtures/memories/`)
+
+| File | Primitive | Purpose |
+|------|-----------|---------|
+| `decision_auth_pattern.md` | decision | JWT/HS256 auth decision with full frontmatter; used by `seeded_memory` fixture |
+| `learning_queue_fix.md` | learning | Atomic queue operations learning; general seeding |
+| `learning_stale.md` | learning | Old (2025), low-confidence (0.3) record; tests archival/decay logic |
+| `learning_duplicate_a.md` | learning | Near-duplicate A; tests deduplication |
+| `learning_duplicate_b.md` | learning | Near-duplicate B; tests deduplication |
+
+There is also a `fixtures/cline/` directory with Cline adapter test data (pre-existing).
+
+## Shared Infrastructure
+
+### `conftest.py`
+
+Shared pytest fixtures available to all tests:
+
+- **`tmp_lerim_root`** — Temporary directory with canonical Lerim folder structure (`memory/decisions`, `memory/learnings`, `memory/summaries`, `memory/archived/*`, `workspace/`, `index/`)
+- **`tmp_config`** — `Config` object pointing at `tmp_lerim_root`
+- **`seeded_memory`** — `tmp_lerim_root` with fixture memory files copied into the correct subdirectories
+- **`skip_unless_env(var)`** — Marker helper that skips unless an env var is set
+
+### `helpers.py`
+
+Shared test utilities:
+
+- **`make_config(base)`** — Builds a deterministic `Config` rooted at a given path. Uses `openrouter`/`qwen/qwen3-coder-30b-a3b-instruct` for all roles (overridable via `LERIM_TEST_PROVIDER`/`LERIM_TEST_MODEL`).
+- **`write_test_config(tmp_path, **sections)`** — Writes a TOML config file for CLI integration tests
+- **`run_cli(args)`** — Runs a CLI command in-process, returns `(exit_code, stdout)`
+- **`run_cli_json(args)`** — Runs a CLI command and parses stdout as JSON
+
+## Environment Variables
+
+| Variable | Required for | Default LLM |
+|----------|-------------|-------------|
+| `LERIM_SMOKE=1` | Smoke tests | `openrouter/qwen/qwen3-coder-30b-a3b-instruct` |
+| `LERIM_INTEGRATION=1` | Integration tests | `openrouter/qwen/qwen3-coder-30b-a3b-instruct` |
+| `LERIM_E2E=1` | E2E tests | `openrouter/qwen/qwen3-coder-30b-a3b-instruct` |
+| `LERIM_TEST_PROVIDER` | Override provider | `openrouter` |
+| `LERIM_TEST_MODEL` | Override model | `qwen/qwen3-coder-30b-a3b-instruct` |
+| `LERIM_CONFIG` | Override config path | `tests/test_config.toml` (auto-applied by conftest) |
+
+## Adding New Tests
+
+- Place unit tests in `tests/test_<module>.py` — no special marker needed.
+- For smoke/integration/e2e, use the appropriate pytest marker and gate with `skip_unless_env`.
+- Add new fixture files to `tests/fixtures/traces/` or `tests/fixtures/memories/` as needed.
+- Each test file must have a docstring at the top explaining what it tests.
+- Each test function should test ONE thing.
+- Update this README if you add new test files, fixtures, or change the test infrastructure.
+
+## DSPy Thread Safety
+
+PydanticAI dispatches tool functions to worker threads via `anyio.to_thread.run_sync()`. DSPy's `dspy.configure(lm=lm)` is **not thread-safe** — it enforces that settings can only be changed by the thread that initially configured them.
+
+The pipelines use `dspy.context(lm=lm)` (a thread-local context manager) instead of `dspy.configure()`. This ensures extract/summarize tools work correctly when called from PydanticAI worker threads. See `extract_pipeline.py` and `summarization_pipeline.py`.
