Viewing a technique page version shows the commit hash in the metadata panel.\n\n## Tasks\n- [x] **T01: Added GIT_COMMIT_SHA build arg to Dockerfile.api, compose build args for api/worker, config field, and _get_git_commit_sha() helper — pipeline metadata now includes git_commit_sha key** — Add GIT_COMMIT_SHA build arg to Dockerfile.api, pass it from docker-compose.yml, write it to /app/.git-commit. Add a helper function in stages.py that reads the SHA from the file (Docker) or runs `git rev-parse --short HEAD` (local dev) with fallback to \"unknown\". Extend `_capture_pipeline_metadata()` to include the `git_commit_sha` key. Add `git_commit_sha` setting to config.py as an additional fallback.\n\n**Important context for executor:** The canonical codebase is on ub01 at `/vmPool/r/repos/xpltdco/chrysopedia`. SSH with `ssh ub01` to edit files and test. The Docker compose stack runs there. The local working directory has .gsd/ planning artifacts only.\n\nSteps:\n1. SSH to ub01, edit `docker/Dockerfile.api` — add `ARG GIT_COMMIT_SHA=unknown` and `RUN echo \"${GIT_COMMIT_SHA}\" > /app/.git-commit` after the `COPY backend/ /app/` line\n2. Edit `docker-compose.yml` — add `args: GIT_COMMIT_SHA: ${GIT_COMMIT_SHA:-unknown}` to both `chrysopedia-api` and `chrysopedia-worker` build sections (they already have `build: context: . dockerfile: docker/Dockerfile.api`)\n3. Edit `backend/config.py` — add `git_commit_sha: str = \"unknown\"` field to Settings class\n4. Edit `backend/pipeline/stages.py` — add `_get_git_commit_sha()` helper that tries: (a) read `/app/.git-commit` file, (b) run `subprocess.run(['git', 'rev-parse', '--short', 'HEAD'])`, (c) return `get_settings().git_commit_sha`, (d) return `\"unknown\"`. Add `\"git_commit_sha\": _get_git_commit_sha()` to the dict returned by `_capture_pipeline_metadata()`\n5. Verify: run `python -c \"from pipeline.stages import _capture_pipeline_metadata; print(_capture_pipeline_metadata())\"` from backend dir (should show git_commit_sha key)\n  - Estimate: 30m\n  - Files: docker/Dockerfile.api, docker-compose.yml, backend/config.py, backend/pipeline/stages.py\n  - Verify: ssh ub01 'cd /vmPool/r/repos/xpltdco/chrysopedia/backend && python -c \"from pipeline.stages import _capture_pipeline_metadata; import json; m = _capture_pipeline_metadata(); assert \\\"git_commit_sha\\\" in m, f\\\"missing key: {m.keys()}\\\"; print(json.dumps(m, indent=2))\"'\n- [x] **T02: Added \"Commit\" row to version metadata panel on TechniquePage — renders abbreviated 7-char git SHA using existing hash-value monospace styling, hidden when SHA is \"unknown\"** — Add a conditional render of `git_commit_sha` in the version metadata panel on TechniquePage.tsx. The panel already renders model, captured_at, and prompt_hashes — add a new item for the commit hash using monospace font.\n\n**Important context for executor:** The canonical codebase is on ub01 at `/vmPool/r/repos/xpltdco/chrysopedia`. SSH with `ssh ub01` to edit files and build. The frontend is at `frontend/` in that repo.\n\nSteps:\n1. SSH to ub01, read `frontend/src/pages/TechniquePage.tsx` lines 315-365 to see existing metadata panel structure\n2. After the `prompt_hashes` conditional block (around line 358) and before the closing `</div>` of `version-metadata__grid`, add a new conditional block checking `\"git_commit_sha\" in versionDetail.pipeline_metadata`. Render it as a `version-metadata__item` with key label \"Commit\" and value in a `<code>` element with monospace font styling (reuse existing `version-metadata__hash-value` class or apply inline). Show first 7 chars: `String(versionDetail.pipeline_metadata.git_commit_sha).slice(0, 7)`\n3. Run `cd frontend && npm run build` to verify zero TypeScript errors\n  - Estimate: 15m\n  - Files: frontend/src/pages/TechniquePage.tsx\n  - Verify: ssh ub01 'cd /vmPool/r/repos/xpltdco/chrysopedia/frontend && npm run build 2>&1 | tail -5'\n\n---\n\n### Requirements\nSource: `.gsd/REQUIREMENTS.md`\n\n# Requirements\n\n## R001 — Whisper Transcription Pipeline\n**Status:** validated\n**Description:** Desktop Python script that accepts video files (MP4/MKV), extracts audio via ffmpeg, runs Whisper large-v3 on RTX 4090, and outputs timestamped transcript JSON with segment-level timestamps and word-level timing.

This causes `relationship(...)` calls below it to fail with \"MappedColumn object is not callable\".\n\n**Fix:** Import with an alias: `from sqlalchemy.orm import relationship as sa_relationship` and use `sa_relationship(...)` throughout. Alternatively, rename the database column, but the spec defines `relationship` as the column name so we preserved it.\n\n## Docker Compose variable interpolation and `:?` syntax\n\n**Context:** `${VAR:?error message}` in docker-compose.yml makes `docker compose config` fail when the variable is unset, even if `env_file: required: false` is used. The `required: false` only controls whether the `.env` file must exist — it does NOT provide defaults for variables referenced with `:?`.\n\n**Fix:** Use `${VAR:-default}` for variables that need a fallback, or ensure the variable is always set in the environment.\n\n## Host port 8000 conflict with kerf-engine\n\n**Context:** The kerf-engine Docker container (`kerf-engine-kerf-engine-1`) binds to `0.0.0.0:8000`. When testing the Chrysopedia API locally (outside Docker), curl requests to `localhost:8000` hit the kerf-engine container instead of the local uvicorn process, even when uvicorn binds to `127.0.0.1:8000`.\n\n**Fix:** Use an alternate port (e.g., 8001) for local testing. In Docker Compose, chrysopedia-api maps `127.0.0.1:8000:8000` which is fine because it goes through Docker's port forwarding, but will conflict with kerf-engine if both stacks run simultaneously. Consider changing one project's external port mapping.\n\n## asyncpg rejects timezone-aware datetimes for TIMESTAMP WITHOUT TIME ZONE columns\n\n**Context:** SQLAlchemy models using `default=datetime.now(timezone.utc)` produce timezone-aware Python datetimes. When the PostgreSQL column type is `TIMESTAMP WITHOUT TIME ZONE` (the default), asyncpg raises `DataError: can't subtract offset-naive and offset-aware datetimes`. This only surfaces when running against a real PostgreSQL database — SQLite-based tests won't catch it.\n\n**Fix:** Use `datetime.now(timezone.utc).replace(tzinfo=None)` in the `_now()` helper, or change the column type to `TIMESTAMP WITH TIME ZONE`. We chose the former since the existing schema uses naive timestamps.\n\n## asyncpg NullPool required for pytest-asyncio integration tests\n\n**Context:** When using a session-scoped SQLAlchemy async engine with asyncpg in pytest-asyncio tests, the connection pool reuses connections across fixtures and test functions. This causes `InterfaceError: cannot perform operation: another operation is in progress` because the ASGI test client's session holds a connection while cleanup/verification fixtures try to use the same pool.\n\n**Fix:** Use `poolclass=NullPool` when creating the test engine. Each connection is created fresh and immediately closed, eliminating contention. Performance cost is negligible for test suites.\n\n## Testing Celery tasks that use sync SQLAlchemy: patch module-level globals\n\n**Context:** Pipeline stages in `pipeline/stages.py` create their own sync SQLAlchemy engine/session via module-level `_engine` and `_SessionLocal` globals (because Celery is sync, not async). Tests need to redirect these to the test database, but the engine is created lazily at module scope.\n\n**Fix:** Patch the module globals directly: `unittest.mock.patch.object(stages, '_engine', test_engine)` and `unittest.mock.patch.object(stages, '_SessionLocal', test_session_factory)`. This redirects all DB access in stage functions to the test database without modifying production code.\n\n## Lazy imports in FastAPI handlers defeat simple mock patching\n\n**Context:** When a FastAPI handler imports a function lazily (inside the function body) like `from pipeline.stages import run_pipeline`, patching `routers.ingest.run_pipeline` has no effect because the name is re-bound on every call from the source module.\n\n**Fix:** Patch at the source module: `unittest.mock.patch('pipeline.stages.run_pipeline')`. The lazy import will pick up the mock from the source module. This applies to any handler that uses lazy imports to avoid circular dependencies at module load time.\n\n## Separate async/sync clients for FastAPI vs Celery\n\n**Context:** The Chrysopedia backend has both sync Celery tasks (pipeline stages using `openai.OpenAI`, `QdrantClient`, sync SQLAlchemy) and async FastAPI handlers. Reusing sync clients in async handlers blocks the event loop; reusing async clients in Celery risks nested event loop errors.\n\n**Fix:** Create separate client classes: `SearchService` (async, for FastAPI request path) wraps `openai.AsyncOpenAI` and `AsyncQdrantClient`. The pipeline's `EmbeddingClient` and `QdrantManager` (sync, for Celery) remain untouched. This doubles the client code surface but eliminates the async/sync mismatch class of bugs entirely.\n\n## Mocking SearchService at the router dependency level for tests\n\n**Context:** The search endpoint creates a `SearchService` instance internally. Testing search results with real embedding API and Qdrant is fragile (external dependencies). Mocking individual `openai.AsyncOpenAI` or `AsyncQdrantClient` is complex.\n\n**Fix:** Mock `SearchService` at the router level by patching the service instance in the endpoint function. This gives full control over search results in tests without complex async mock setup. Used in `test_search.py` — mock returns canned `SearchResponse` dicts.\n\n## Frontend detail page without a single-resource GET endpoint\n\n**Context:** The review queue backend has `GET /review/queue` (list, paginated) but no `GET /review/moments/{id}` for fetching a single moment. The MomentDetail page needs to display one specific moment by ID from the URL params.\n\n**Fix:** MomentDetail fetches the full queue with `limit=500` and filters client-side by ID. This works for a single-admin tool with small datasets but would not scale. If the moment count grows significantly, add a dedicated `GET /review/moments/{id}` endpoint to the review router.\n\n**Update (M004/S01):** Fixed properly — added `GET /review/moments/{id}` endpoint. Always add single-resource GET endpoints alongside list endpoints.\n\n## CSS custom property count estimation\n\n**Context:** When planning a full color abstraction pass (replacing all hardcoded hex/rgba with CSS custom properties), initial estimates based on counting unique colors will significantly undercount the required tokens.\n\n**Rule:** Plan for 2-3x the obvious color count. Reasons: hover/focus/active state variants, badge/status color pairs (background + text), subtle vs strong accent variants, shadow colors, overlay backgrounds, and distinct semantic contexts (surface vs input vs card). M004/S02 planned ~30, needed 77.\n\n## Chained selectinload for cross-relation field population\n\n**Context:** When an API response needs a field from a joined relation (e.g., `key_moment.source_video.filename`), Pydantic's `from_attributes` auto-mapping can't traverse the join. The field appears as a flat attribute on the response schema but comes from a different table.\n\n**Fix:** Chain `.selectinload()` in the query (e.g., `.selectinload(TechniquePage.key_moments).selectinload(KeyMoment.source_video)`), then post-process in a loop to copy the joined value into the schema field. This keeps the query efficient (two SELECTs) and the response schema flat.\n\n## Pre-overwrite snapshot pattern for article versioning\n\n**Context:** Need to track content versions without complex CDC (change data capture) infrastructure. The content lives in a single mutable row that gets overwritten on each pipeline run.\n\n**Pattern:** Before mutating the row, SELECT its current state, serialize relevant fields to JSONB (`content_snapshot`), attach pipeline metadata (prompt file hashes, model config) as a second JSONB column, and INSERT into a versions table. Use best-effort error handling — snapshot failure logs ERROR but doesn't block the primary write. Composite unique index on (entity_id, version_number) enforces ordering at DB level.\n\n## Stage 4 classification data stored in Redis (not DB columns)\n\n**Context:** The KeyMoment SQLAlchemy model doesn't have `topic_tags` or `topic_category` columns. Stage 4 classification needs somewhere to store per-moment tag assignments that stage 5 can read.\n\n**Fix:** Store classification results in Redis under key `chrysopedia:classification:{video_id}` with a 24-hour TTL. Stage 5 reads from Redis. This avoids schema migrations during initial pipeline development. The data is ephemeral — if Redis loses it, re-running stage 4 regenerates it.\n\n## QdrantManager uses random UUIDs for point IDs\n\n**Context:** `QdrantManager.upsert_technique_pages()` and `upsert_key_moments()` generate `uuid4()` for each Qdrant point. Re-indexing the same content creates duplicate points rather than updating existing ones.\n\n**Fix (deferred):** Use deterministic UUIDs based on content hash (e.g., `uuid5(NAMESPACE, f\"{technique_slug}:{section}\")`) so re-indexing overwrites the same points. This should be addressed before running the pipeline on production data to avoid index bloat.\n\n## Non-blocking side-effect pattern for external service calls in pipelines\n\n**Context:** Celery pipeline stages that call external services (embedding API, Qdrant) should not fail the entire pipeline if those services are down. Stage 6 (embed_and_index) is valuable but not critical — the pipeline's primary output (technique pages in PostgreSQL) doesn't depend on it.\n\n**Fix:** Use `max_retries=0` and a catch-all exception handler that logs WARNING and returns without raising. The pipeline orchestrator chains stage 6 after stage 5 but a failure there doesn't prevent `processing_status` from reaching its final state. This pattern applies to any \"best-effort enrichment\" stage in a pipeline.\n\n## Container healthcheck tool availability varies by base image\n\n**Context:** Qdrant (distroless-ish), Ollama, and nginx-alpine images don't have curl or wget. Standard healthcheck patterns like `curl -f http://localhost:PORT/health` fail silently inside these containers.\n\n**Fix by image:**\n- **Ollama:** Use `ollama list` (built-in CLI)\n- **Qdrant:** Use `bash -c 'echo > /dev/tcp/localhost/6333'` (bash is available)\n- **nginx-alpine:** Use `curl` (available) but NOT busybox `wget` (fails on localhost)\n- **Celery worker (same image as API):** Use `celery -A worker inspect ping` instead of HTTP healthcheck\n\n**Rule:** Always `docker exec <container> <healthcheck-cmd>` to verify the command works before deploying.\n\n## XPLTD domain setup flow\n\n**Context:** Adding a new external domain (like chrysopedia.com) to the XPLTD infrastructure requires three steps across two machines.\n\n**Flow:**\n1. **AdGuard on ub01 (10.0.0.10):** Add DNS rewrite via API: `POST /control/rewrite/add` with `{domain, answer: \"10.0.0.9\"}`\n2. **nginx on nuc01 (10.0.0.9):** Create server block in `/etc/nginx/sites-enabled/{domain}.conf` with `proxy_pass http://10.0.0.10:{port}`\n3. **Certbot on nuc01:** `sudo certbot --nginx -d {domain}` (requires external DNS A record or CNAME pointing to public IP first)\n\n**Note:** The AD DNS servers (10.0.0.15/.16) may already have CNAME entries for domains. Check `nslookup {domain} 10.0.0.15` before assuming setup is needed. ub01's resolv.conf uses AD DNS, not AdGuard, so `curl {domain}` from ub01 requires the AD DNS chain to resolve.\n\n## Alembic env.py sys.path needs both local and Docker paths\n\n**Context:** Alembic's env.py imports from `database` and `models`, which live in `backend/` locally but at `/app/` (the WORKDIR) inside Docker. The original `sys.path.insert(0, \"../backend\")` works locally but fails in Docker.\n\n**Fix:** Add both paths: `sys.path.insert(0, os.path.join(os.path.dirname(__file__), \"..\", \"backend\"))` AND `sys.path.insert(0, os.path.join(os.path.dirname(__file__), \"..\"))`. The second resolves to `/app/` inside Docker.\n\n## Nginx stale DNS after Docker container rebuild\n\n**Context:** When an API container behind an nginx reverse proxy in Docker Compose is rebuilt (new container ID, new internal IP), the nginx container's DNS resolver cache still points to the old IP. Requests through nginx return 502 Bad Gateway even though the API is healthy on its new IP.\n\n**Fix:** Restart the nginx/web container after rebuilding upstream containers: `docker compose restart chrysopedia-web-8096`. Alternatively, configure nginx with `resolver 127.0.0.11 valid=10s;` in the upstream block to use Docker's embedded DNS with a short TTL, but the restart is simpler for a single-admin deployment.\n\n## Verify prior incomplete code compiles before building on it\n\n**Context:** M005/S01/T01 found that the PipelineEvent model, migration, and instrumentation hooks had been written in a prior pass but contained critical syntax errors (missing triple-quote docstrings, unquoted string literals, reference to nonexistent `_get_session_factory()`). The code looked complete in the file listing but had never been successfully executed.\n\n**Rule:** When a slice plan assumes prior work is complete (\"model already exists, migration already applied\"), verify it actually runs: import the module, run the migration, execute a basic query. Broken code that's already committed looks identical to working code in `git log`.\n\n---\n\n### Task Summary: T01\nSource: `.gsd/milestones/M006/slices/S03/tasks/T01-SUMMARY.md`\n\n---\nid: T01\nparent: S03\nmilestone: M006\nprovides: []\nrequires: []\naffects: []\nkey_files: [\"docker/Dockerfile.api\", \"docker-compose.yml\", \"backend/config.py\", \"backend/pipeline/stages.py\"]\nkey_decisions: [\"Resolution order for git SHA: .git-commit file → git rev-parse → config/env → unknown\"]\npatterns_established: []\ndrill_down_paths: []\nobservability_surfaces: []\nduration: \"\"\nverification_result: \"Ran _capture_pipeline_metadata() inside chrysopedia-api container — assertion passed, git_commit_sha key present with expected \"unknown\" fallback value.

A complex slice with 5 tasks across multiple subsystems needs thorough verification and a detailed summary. Scale the work below accordingly.\n\nThen:\n1. Use the **Slice Summary** and **UAT** output templates from the inlined context above\n2. If a `GSD Skill Preferences` block is present in system context, use it and the `<available_skills>` catalog in your system prompt to decide which skills to load and follow for this unit, without relaxing required verification or artifact rules.\n3. Run all slice-level verification checks defined in the slice plan. All must pass before marking the slice done. If any fail, fix them first.\n4. If the slice plan includes observability/diagnostic surfaces, confirm they work. Skip this for simple slices that don't have observability sections.\n5. If the slice involved runtime behavior, fill the **Operational Readiness** section (Q8) in the slice summary: health signal, failure signal, recovery procedure, and monitoring gaps. Omit entirely for simple slices with no runtime concerns.\n6. If this slice produced evidence that a requirement changed status (Active → Validated, Active → Deferred, etc.), call `gsd_save_decision` with scope=\"requirement\", decision=\"{requirement-id}\", choice=\"{new-status}\", rationale=\"{evidence}\". Do NOT write `.gsd/REQUIREMENTS.md` directly — the engine renders it from the database.\n7. Write `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M006/slices/S03/S03-SUMMARY.md` (compress all task summaries).\n8. Write `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M006/slices/S03/S03-UAT.md` — a concrete UAT script with real test cases derived from the slice plan and task summaries. Include preconditions, numbered steps with expected outcomes, and edge cases. This must NOT be a placeholder or generic template — tailor every test case to what this slice actually built.\n9. Review task summaries for `key_decisions`. Append any significant decisions to `.gsd/DECISIONS.md` if missing.\n10. Review task summaries for patterns, gotchas, or non-obvious lessons learned. If any would save future agents from repeating investigation or hitting the same issues, append them to `.gsd/KNOWLEDGE.md`. Only add entries that are genuinely useful — don't pad with obvious observations.\n11. Call `gsd_complete_slice` with milestone_id, slice_id, the slice summary, and the UAT result. Do NOT manually mark the roadmap checkbox — the tool writes to the DB and renders the ROADMAP.md projection automatically.\n12. Do not run git commands — the system commits your changes and handles any merge after this unit succeeds.\n13. Update `.gsd/PROJECT.md` if it exists — refresh current state if needed.\n\n**You MUST call `gsd_complete_slice` with the slice summary and UAT content before finishing. The tool persists to both DB and disk and renders `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M006/slices/S03/S03-SUMMARY.md` and `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M006/slices/S03/S03-UAT.md` automatically.**\n\nWhen done, say: \"Slice S03 complete.\"","display":false,"id":"640f8152","parentId":"f2261b81","timestamp":"2026-03-30T11:25:47.301Z"}

Look for a \"Commit\" row\n\n**Expected:** \"Commit\" row shows a 7-character hex string (e.g., `a1b2c3d`), rendered in monospace font matching the prompt hash styling.\n\n### Edge Cases\n- **No version data:** Technique pages without version history don't show the metadata panel at all — no crash expected.\n- **SHA longer than 7 chars:** Display truncates to first 7 characters regardless of full SHA length.\n- **Empty string SHA:** Treated same as any non-\"unknown\" value — would show empty code tag. Low risk since the fallback chain always produces either a real SHA or \"unknown\".","verification":"1. `ssh ub01 'cd /vmPool/r/repos/xpltdco/chrysopedia/frontend && npm run build 2>&1 | tail -5'` — exit 0, clean build in 696ms\n2. `docker exec chrysopedia-api python -c \"from pipeline.stages import _capture_pipeline_metadata; ...\"` — exit 0, git_commit_sha key present with \"unknown\" fallback\n3.
