You are the closer — verify the assembled work actually delivers the slice goal, then compress everything into a slice summary. After you finish, a **reassess-roadmap agent** reads your slice summary to decide if the remaining roadmap still makes sense. The slice summary is also the primary record of what this slice achieved — future slice researchers and planners read it as a dependency summary when their work builds on yours.\n\nWrite the summary for those downstream readers. What did this slice actually deliver? What patterns did it establish? What should the next slice know?\n\nAll relevant context has been preloaded below — the slice plan, all task summaries, and the milestone roadmap are inlined. Start working immediately without re-reading these files.\n\n## Inlined Context (preloaded — do not re-read these files)\n\n### Milestone Roadmap\nSource: `.gsd/milestones/M008/M008-ROADMAP.md`\n\n# M008: \n\n## Vision\nFix the broken and embarrassing things first. Key moment links that 404, test data in production, jargon banners, empty metrics — these erode trust before a visitor even evaluates the content.

Three areas need changes:\n\n1. **Qdrant payload enrichment** (`backend/pipeline/qdrant_client.py` + `backend/pipeline/stages.py`): Add `slug` to technique page payloads and `technique_page_slug`/`technique_page_id` to key moment payloads. The stage 6 code in `stages.py` (~line 960) builds `page_dicts` and `moment_dicts` — add the missing fields there. For moments, build a `page_id_to_slug` mapping from the `pages` list, then look up each moment's `technique_page_id` to get the slug.\n\n2. **Search service** (`backend/search_service.py`):\n   - `_enrich_results()` (~line 310): Currently falls back to `title.lower().replace(' ', '-')` for slug. Add `technique_page_slug` to the enriched dict, reading from `payload.get('technique_page_slug', '')`. For technique pages, use `payload.get('slug', '')` directly (no longer need the naive fallback once re-indexed, but keep it as fallback for old data).\n   - `keyword_search()` (~line 137): Key moment results currently set `slug: ''`. Add an outerjoin to `TechniquePage` via `KeyMoment.technique_page_id == TechniquePage.id` to get the parent slug. Add `technique_page_slug` to the result dict.\n   - Also add `technique_page_slug` to technique_page keyword results (set to same as `slug` — a technique page IS its own parent).\n\n3. **Schema** (`backend/schemas.py`): Add `technique_page_slug: str = ''` to `SearchResultItem`.\n\n4. **Tests** (`backend/tests/test_search.py`): Update the keyword fallback test to verify `technique_page_slug` is present in results. Add a test for key moment keyword search returning the correct parent technique page slug.\n  - Estimate: 45m\n  - Files: backend/pipeline/stages.py, backend/pipeline/qdrant_client.py, backend/search_service.py, backend/schemas.py, backend/tests/test_search.py\n  - Verify: cd /home/aux/projects/content-to-kb-automator && python -m pytest backend/tests/test_search.py -v 2>&1 | tail -30\n- [x] **T02: Key moment search results now link to parent technique page with hash-scroll to the specific moment** — Fix the frontend so clicking a key moment search result navigates to the parent technique page and scrolls to the specific moment.\n\n1. **TypeScript interface** (`frontend/src/api/public-client.ts`): Add `technique_page_slug?: string` to the `SearchResultItem` interface (line ~10).\n\n2. **Search result card** (`frontend/src/pages/SearchResults.tsx`): In `SearchResultCard` (~line 145), the `<Link>` currently always goes to `/techniques/${item.slug}`. Change to:\n   - If `item.type === 'key_moment'` and `item.technique_page_slug`: link to `/techniques/${item.technique_page_slug}#km-${item.slug || item.title}`\n   - If `item.type === 'key_moment'` but no `technique_page_slug`: link to `/search?q=${encodeURIComponent(item.title)}` (graceful fallback — don't 404)\n   - Otherwise (technique_page): keep `/techniques/${item.slug}`\n\n3. **Key moment anchors** (`frontend/src/pages/TechniquePage.tsx`): The `<li key={km.id}>` at ~line 421 has no `id` attribute. Add `id={`km-${km.id}`}` to the `<li>` element so hash fragments can target specific moments.\n\n4. **Scroll-to-hash** (`frontend/src/pages/TechniquePage.tsx`): Add a `useEffect` that runs after technique data loads. If `window.location.hash` starts with `#km-`, find the element by ID and call `scrollIntoView({ behavior: 'smooth', block: 'start' })`. The effect should depend on `technique` (the loaded data) so it fires after render.\n\n5. **Build verification**: Run `npm run build` in the frontend to ensure no TypeScript errors.\n  - Estimate: 30m\n  - Files: frontend/src/api/public-client.ts, frontend/src/pages/SearchResults.tsx, frontend/src/pages/TechniquePage.tsx\n  - Verify: cd /home/aux/projects/content-to-kb-automator/frontend && npm run build 2>&1 | tail -20\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 applies to any slim-based image where a healthcheck needs to verify the main process is alive.\n\n**Fix:** Use `python -c \"import os; os.kill(1, 0)\"` as the healthcheck command. PID 1 is always the container's entrypoint process. `os.kill(pid, 0)` checks if the process exists without sending a signal — it raises `ProcessLookupError` if the process is dead, causing the healthcheck to fail. No external tools needed.\n\n## SQLAlchemy column names that shadow ORM functions\n\n**Context:** If a model has a column named `relationship` (or any other ORM function name like `query`, `metadata`), Python resolves the name to the column's `MappedColumn` descriptor within the class body. 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## Vite build-time constant injection requires JSON.stringify\n\n**Context:** Vite's `define` config replaces identifiers at build time with string literals. If you write `define: { __APP_VERSION__: version }` where `version` is a JS string, the replacement is the raw value without quotes — the built code gets `const v = 0.1.0` (syntax error) instead of `const v = \"0.1.0\"`.\n\n**Fix:** Always wrap with `JSON.stringify`: `define: { __APP_VERSION__: JSON.stringify(version) }`. Declare the constants in `vite-env.d.ts` as `declare const __APP_VERSION__: string` for TypeScript.\n\n## Docker ARG→ENV ordering matters for Vite/Node builds\n\n**Context:** In a Dockerfile that runs `npm run build` to produce a static frontend bundle, Vite reads environment variables at build time. A `ARG VITE_FOO=default` alone isn't visible to Node unless also set as `ENV VITE_FOO=$VITE_FOO`. The `ENV` line must appear BEFORE the `RUN npm run build` step.\n\n**Fix:** Pattern is `ARG VITE_FOO=default` → `ENV VITE_FOO=$VITE_FOO` → `RUN npm run build`. In docker-compose.yml, pass build args: `build: args: VITE_FOO: ${HOST_VAR:-default}`.\n\n## Slim Python Docker images lack procps (pgrep/ps)\n\n**Context:** The `python:3.x-slim` base image (used by Dockerfile.api) does not include `procps`, so `pgrep`, `ps`, and `pidof` are unavailable. Healthcheck commands like `pgrep -f watcher.py || exit 1` silently fail because the binary doesn't exist.\n\n**Fix:** Use Python for process healthchecks: `python -c \"import os; os.kill(1, 0)\" || exit 1`. This sends signal 0 to PID 1 (the container's main process), which succeeds if the process exists without actually sending a signal. Works for any single-process container where PID 1 is the service.\n\n## PollingObserver over inotify for ZFS/NFS folder watchers\n\n**Context:** Python watchdog's default `Observer` uses inotify on Linux, which doesn't reliably detect file changes on ZFS datasets or NFS mounts. The watcher silently misses file creation events.\n\n**Fix:** Use `watchdog.observers.polling.PollingObserver` instead. It polls the filesystem at configurable intervals (default 1s). Slightly higher CPU usage but works reliably on any filesystem type.\n\n## File stability detection for folder watchers receiving SCP/rsync writes\n\n**Context:** When files land via SCP or rsync, the filesystem sees partial writes before the transfer completes. A watcher that processes on first `on_created` event may read an incomplete file.\n\n**Fix:** After detecting a new file, check file size at two points separated by a delay (e.g., 2 seconds). Only process when the size is stable. This handles both SCP (which writes incrementally) and rsync (which may use a temp file then rename, but the rename triggers a new event with the final size).\n\n## Check toggle state once at initialization, not per-operation\n\n**Context:** When a feature toggle (e.g., debug mode) controls whether extra work happens on every operation (e.g., storing full LLM I/O on every API call), checking the toggle per-operation adds latency (Redis round-trip) on every call even when the feature is off.\n\n**Fix:** Check the toggle once when creating the callback/handler closure, and let the closure capture the boolean. The trade-off is that toggle changes don't take effect until the next pipeline run (not mid-run), which is acceptable for diagnostic features.\n\n---\n\n### Task Summary: T01\nSource: `.gsd/milestones/M008/slices/S01/tasks/T01-SUMMARY.md`\n\n[...truncated 23 sections]\n\n**Match effort to complexity.** A simple slice with 1-2 tasks needs a brief summary and lightweight verification. 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/M008/slices/S01/S01-SUMMARY.md` (compress all task summaries).\n8. Write `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M008/slices/S01/S01-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/M008/slices/S01/S01-SUMMARY.md` and `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M008/slices/S01/S01-UAT.md` automatically.**\n\nWhen done, say: \"Slice S01 complete.\"","display":false,"id":"a94a2144","parentId":"570d7289","timestamp":"2026-03-31T05:04:06.036Z"}

The fix required coordinated backend and frontend changes across two tasks.\n\n**T01 (Backend):** Added `technique_page_slug` to the search result data flow. Four areas changed: (1) `SearchResultItem` schema gained a `technique_page_slug` field. (2) Qdrant payload enrichment in stage 6 now includes `slug` on technique page dicts and `technique_page_slug`/`technique_page_id` on key moment dicts via a `page_id_to_slug` mapping. (3) The search service's `_enrich_results()` reads `technique_page_slug` from Qdrant payloads; `keyword_search()` uses an outerjoin to TechniquePage to resolve the parent slug for key moments. (4) Three new integration tests verify correct slug population for technique pages, key moments with parents, and orphan moments.\n\n**T02 (Frontend):** Three changes: (1) `SearchResultCard` routing now sends key moment clicks to `/techniques/{parent_slug}#km-{id}` (with a re-search fallback if no parent slug exists). (2) Key moment `<li>` elements in `TechniquePage` gained `id={`km-${km.id}`}` anchor attributes. (3) A `useEffect` scrolls to the hash target after technique data loads, using `scrollIntoView({ behavior: 'smooth', block: 'start' })`.","observabilitySurfaces":[],"oneLiner":"Key moment search results now link to their parent technique page and scroll to the specific moment, instead of 404ing.","patternsEstablished":["Cross-entity link resolution: when search results reference a parent entity, resolve the parent slug at query time (DB join for keyword, payload enrichment for semantic) rather than expecting the frontend to make a second API call","Hash-scroll pattern: anchor IDs on target elements + useEffect that fires after data load to scrollIntoView"],"provides":["technique_page_slug field on all SearchResultItem responses","Hash-scroll anchors (km-{id}) on key moment list items in TechniquePage"],"requirementsAdvanced":[{"how":"Key moment search results no longer 404 — they link to the parent technique page with hash-scroll to the specific moment","id":"R005"},{"how":"Eliminating the 404 dead-end on key moment clicks removes a significant time-waster from the search-to-read flow","id":"R015"}],"requirementsInvalidated":[],"requirementsSurfaced":[],"requirementsValidated":[],"requires":[],"sliceId":"S01","sliceTitle":"Fix Key Moment Search Links","uatContent":"## UAT: Fix Key Moment Search Links\n\n### Preconditions\n- Chrysopedia stack running on ub01 (docker ps shows all containers healthy)\n- At least one technique page with key moments exists in the database\n- Qdrant has been re-indexed after deployment (or title-based fallback is acceptable for semantic results)\n\n### Test 1: Key Moment Semantic Search → Parent Page Navigation\n1. Open http://ub01:8096\n2. Type \"compression\" in the search bar\n3. Wait for results to appear\n4. Identify a result with type \"key_moment\" (shown with a moment/clip icon)\n5. Click the key moment result\n6. **Expected:** Browser navigates to `/techniques/{parent-technique-slug}#km-{moment-id}` — the parent technique page loads and the page scrolls to the specific key moment in the key moments list\n\n### Test 2: Key Moment Keyword Search → Parent Page Navigation\n1. Open http://ub01:8096\n2. Type a query that matches a key moment title via keyword search (e.g., a specific technique name that exists as a key moment)\n3. Click the key moment result\n4. **Expected:** Same as Test 1 — navigates to parent technique page with hash-scroll\n\n### Test 3: Technique Page Search → Normal Navigation (No Regression)\n1. Open http://ub01:8096\n2. Search for a term that matches a technique page title\n3. Click the technique page result\n4. **Expected:** Navigates to `/techniques/{slug}` — the technique page loads normally (no hash fragment, no scroll behavior)\n\n### Test 4: Hash-Scroll Works on Direct URL\n1. Open a technique page URL directly in the browser\n2. Find a key moment ID from the page (inspect element on any key moment `<li>` — look for `id=\"km-{uuid}\"`)\n3. Append `#km-{that-uuid}` to the URL and reload\n4. **Expected:** Page loads and scrolls smoothly to the specific key moment\n\n### Test 5: Missing Parent Slug Fallback\n1. If any key moment in the database has a NULL technique_page_id (orphan moment):\n   - Search for it\n   - Click the result\n   - **Expected:** Browser navigates to a search page with the moment's title as the query — NOT a 404 page\n\n### Edge Cases\n- **Empty search results:** Search for gibberish → no results shown, no errors in console\n- **Key moment at top of page:** If the target moment is the first in the list, scrollIntoView should still work (no-op if already visible)\n- **Browser back button:** After navigating from search to technique page via key moment link, pressing Back returns to search results","verification":"Backend: All 8 tests pass (5 existing + 3 new) via `python -m pytest tests/test_search.py -v` inside chrysopedia-api container on ub01 (2.88s).
