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/M005/M005-ROADMAP.md`\n\n# M005: \n\n## Vision\nAdd a pipeline management dashboard under admin (trigger, pause, monitor, view logs/token usage/JSON responses), redesign technique pages with a 2-column layout (prose left, moments/chains/plugins right), and clean up key moment card presentation for consistent readability.\n\n## Slice Overview\n| ID | Slice | Risk | Depends | Done | After this |\n|----|-------|------|---------|------|------------|\n| S01 | Pipeline Admin Dashboard | high | — | ✅ | Admin page at /admin/pipeline shows video list with status, retrigger button, and log viewer with token counts and expandable JSON responses |\n| S02 | Technique Page 2-Column Layout | medium | — | ⬜ | Technique page shows prose content on left, plugins/moments/chains on right at desktop widths. Single column on mobile. |\n| S03 | Key Moment Card Redesign | low | S02 | ⬜ | Key moment cards show title prominently on its own line, with source file, timestamp, and type badge on a clean secondary row |\n\n---\n\n### Slice Plan\nSource: `.gsd/milestones/M005/slices/S02/S02-PLAN.md`\n\n# S02: Technique Page 2-Column Layout\n\n**Goal:** Technique page shows prose content (summary + body sections) on the left and sidebar content (key moments, signal chains, plugins, related techniques) on the right at desktop widths, collapsing to a single column on mobile/tablet.\n**Demo:** After this: Technique page shows prose content on left, plugins/moments/chains on right at desktop widths. Single column on mobile.\n\n## Tasks\n- [x] **T01: Added CSS grid layout splitting technique page into prose (left) and sidebar (right) columns, collapsing to single column on mobile** — Add a CSS grid wrapper to TechniquePage.tsx that places summary + body sections in the left column and key moments + signal chains + plugins + related techniques in the right column. Add corresponding CSS grid rules to App.css with a responsive breakpoint at 768px that collapses to single column. Widen .technique-page max-width from 48rem to ~64rem to accommodate the sidebar.\n\nThe executor should work on the ub01 remote repo at /vmPool/r/repos/xpltdco/chrysopedia since that's the canonical development directory. Use SSH commands or work locally and push.\n\n## Steps\n\n1. Read `frontend/src/App.css` lines around the `.technique-page` rule (line ~1179) and the technique section CSS (lines 1179–1420) to understand current spacing.\n\n2. In `frontend/src/App.css`, change `.technique-page { max-width: 48rem }` to `max-width: 64rem`.\n\n3. Add new CSS grid rules after the `.technique-page` block:\n   ```css\n   .technique-columns {\n     display: grid;\n     grid-template-columns: 1fr 22rem;\n     gap: 2rem;\n     align-items: start;\n   }\n   .technique-columns__main {\n     min-width: 0; /* prevent grid blowout */\n   }\n   .technique-columns__sidebar {\n     position: sticky;\n     top: 1.5rem;\n   }\n   @media (max-width: 768px) {\n     .technique-columns {\n       grid-template-columns: 1fr;\n     }\n     .technique-columns__sidebar {\n       position: static;\n     }\n   }\n   ```\n\n4. In `frontend/src/pages/TechniquePage.tsx`, wrap the content sections in a grid container. After the header/report-modal and before the `{/* Summary */}` comment, open a `<div className=\"technique-columns\">` with two children:\n   - `<div className=\"technique-columns__main\">` containing the Summary section and Body Sections\n   - `<div className=\"technique-columns__sidebar\">` containing Key Moments, Signal Chains, Plugins, and Related Techniques\n   Close the `.technique-columns` div after the Related Techniques section.\n\n5. Run `cd frontend && npx tsc --noEmit` to verify no TypeScript errors.\n\n6. Run `cd frontend && npm run build` to verify production build succeeds.\n\n7. Rebuild and restart the web container on ub01: `docker compose build chrysopedia-web-8096 && docker compose up -d chrysopedia-web-8096`\n\n8. Visually verify at http://ub01:8096/techniques/ (pick any technique slug) that:\n   - At desktop width: prose on left, sidebar on right\n   - At narrow width (<768px): single column\n   - Header spans full width above both columns\n   - Existing 640px mobile styles still work (title size reduction, etc.)\n\n## Must-Haves\n\n- [ ] `.technique-page` max-width widened from 48rem to ~64rem\n- [ ] New `.technique-columns` CSS grid with `1fr 22rem` columns\n- [ ] Summary + body sections in left column\n- [ ] Key moments + signal chains + plugins + related in right column\n- [ ] Responsive collapse to 1 column at ≤768px\n- [ ] Sidebar sticky positioning at desktop widths\n- [ ] `npx tsc --noEmit` passes\n- [ ] `npm run build` succeeds\n- [ ] All CSS uses existing custom properties (no new hardcoded colors)\n  - Estimate: 45m\n  - Files: frontend/src/pages/TechniquePage.tsx, frontend/src/App.css\n  - Verify: cd frontend && npx tsc --noEmit && npm run build\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---\n\n### Task Summary: T01\nSource: `.gsd/milestones/M005/slices/S02/tasks/T01-SUMMARY.md`\n\n---\nid: T01\nparent: S02\nmilestone: M005\nprovides: []\nrequires: []\naffects: []\nkey_files: [\"frontend/src/App.css\", \"frontend/src/pages/TechniquePage.tsx\"]\nkey_decisions: [\"Sidebar fixed at 22rem width with sticky positioning at 1.5rem from top\", \"Page max-width widened from 48rem to 64rem\"]\npatterns_established: []\ndrill_down_paths: []\nobservability_surfaces: []\nduration: \"\"\nverification_result: \"TypeScript compilation (tsc --noEmit) passed with zero errors.

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/M005/slices/S02/S02-SUMMARY.md` (compress all task summaries).\n8. Write `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M005/slices/S02/S02-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/M005/slices/S02/S02-SUMMARY.md` and `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M005/slices/S02/S02-UAT.md` automatically.**\n\nWhen done, say: \"Slice S02 complete.\"","display":false,"id":"6b11ac7b","parentId":"1178f547","timestamp":"2026-03-30T08:47:56.858Z"}

The system is deployed and running on ub01 at `http://ub01:8096`.\n\n### What's Built\n\n- **Transcription pipeline** — Desktop script: video → ffmpeg audio extraction → Whisper large-v3 → timestamped transcript JSON\n- **6-stage LLM extraction pipeline** — Transcript segmentation → key moment extraction → classification/tagging → technique page synthesis → embedding/indexing. Per-stage model routing (chat vs thinking models). Resumable per-video per-stage.\n- **Article versioning** — Pre-overwrite snapshots with pipeline metadata (prompt SHA-256 hashes, model config) for benchmarking extraction quality across prompt iterations.\n- **Review queue UI** — Admin interface for approving/editing/rejecting extracted key moments.\n- **Search-first web UI** — Dark theme with cyan accents. Semantic search (Qdrant), topic/creator browse pages, technique detail pages with signal chain blocks and video source metadata.\n- **Docker Compose deployment** — API, worker, web, PostgreSQL, Redis, Qdrant, Ollama on ub01 with bind mounts at `/vmPool/r/services/chrysopedia_*`.\n- **Prompt template system** — Editable per-stage prompt files with SHA-256 tracking for reproducibility.\n\n### Stack\n\n- **Backend:** FastAPI + Celery + SQLAlchemy (async) + PostgreSQL + Redis + Qdrant\n- **Frontend:** React + TypeScript + Vite\n- **LLM:** OpenAI-compatible API (DGX Sparks Qwen primary, local Ollama fallback)\n- **Deployment:** Docker Compose on ub01, nginx reverse proxy on nuc01\n\n- **Pipeline admin dashboard** — Admin page at `/admin/pipeline` with video list, status badges, retrigger/revoke controls, expandable event log with token usage, collapsible JSON response viewer, and live worker status indicator. Pipeline events instrumented via `PipelineEvent` model (stage, event_type, token counts, JSONB payload).\n\n### Milestone History\n\n| ID | Title | Status |\n|----|-------|--------|\n| M001 | Chrysopedia Foundation — Infrastructure, Pipeline Core, and Skeleton UI | ✅ Complete |\n| M002 | Deployment — GitHub, ub01 Docker Stack, and Production Wiring | ✅ Complete |\n| M003 | Domain + DNS + Per-Stage LLM Model Routing | ✅ Complete |\n| M004 | UI Polish, Bug Fixes, Technique Page Redesign, and Article Versioning | ✅ Complete |\n| M005 | Pipeline Dashboard, Technique Page Redesign, Key Moment Cards | 🔧 In Progress |\n"}],"isError":false,"timestamp":1774860523499}}

At ≤768px the grid collapses to a single column with static positioning, preserving the existing mobile experience.\n\nIn TechniquePage.tsx, the content below the header/report-modal was wrapped in the grid container. The main column contains the Summary section and Body Sections (study guide prose). The sidebar column contains Key Moments, Signal Chains, Plugins, and Related Techniques. The header and report modal remain above the grid at full width.\n\nAll new CSS uses only structural properties (grid, gap, positioning) with no hardcoded colors, staying consistent with the existing custom property system.

Open http://ub01:8096/techniques/ in a desktop browser (viewport ≥1024px wide)\n2. Click any technique with key moments listed\n3. **Expected:** Page header (title, tags, creator info) spans full width\n4. **Expected:** Below the header, content splits into two columns — prose (summary + study guide sections) on the left, sidebar (key moments, signal chains, plugins, related techniques) on the right\n5. **Expected:** Sidebar is approximately 22rem wide; main content fills remaining space\n6. **Expected:** 2rem gap visible between columns\n\n#### TC2: Sticky Sidebar\n1. On the same technique page at desktop width, scroll down through the prose content\n2. **Expected:** The sidebar remains pinned near the top of the viewport (sticky at ~1.5rem from top) while the main content scrolls\n3. **Expected:** If sidebar content is taller than the viewport, it scrolls independently\n\n#### TC3: Mobile Single-Column Collapse\n1. Resize browser window to ≤768px width (or use DevTools mobile emulation at 375px)\n2. **Expected:** Layout collapses to a single column — all content stacks vertically\n3. **Expected:** Sidebar content (key moments, etc.) appears below the prose content, not beside it\n4. **Expected:** Sidebar is no longer sticky — it scrolls naturally with the page\n\n#### TC4: Page Width\n1. At desktop width, inspect the technique page container\n2. **Expected:** Max-width is 64rem (was previously 48rem), providing enough horizontal room for both columns\n\n#### TC5: No Visual Regressions\n1. Navigate to a technique page with all sections populated (summary, body sections, key moments, signal chains, plugins, related techniques)\n2. **Expected:** All sections render correctly — no overlapping text, no content cut off, no broken spacing\n3. **Expected:** Existing styling (colors, typography, badges, cards) is unchanged\n4. **Expected:** Dark theme custom properties still apply — no raw hex colors visible in new layout elements\n\n#### TC6: Empty Sidebar Sections\n1. Navigate to a technique page that has no plugins or no signal chains\n2. **Expected:** Empty sections are absent from the sidebar (not rendered as blank space)\n3. **Expected:** The remaining sidebar sections display correctly without extra gaps\n\n### Edge Cases\n\n#### EC1: Very Long Prose Content\n1. Find or create a technique with many body sections (5+ sub-headings)\n2. **Expected:** Main column handles the long content naturally — no overflow, no grid blowout\n3. **Expected:** Sidebar sticky behavior works correctly during extended scrolling\n\n#### EC2: Technique with Many Key Moments\n1. Find a technique with 10+ key moments\n2. **Expected:** Sidebar handles the long list — scrollable within the viewport if needed\n3. **Expected:** At mobile widths, the moment list displays fully in the single-column flow","verification":"TypeScript compilation (tsc --noEmit) passed with zero errors.
