Defined 77 semantic tokens in a `:root` block covering: page/surface/input backgrounds, primary/secondary/muted text, borders, cyan accent (replacing indigo throughout), status badge variants (pending/approved/edited/rejected with dark-appropriate tints), button states, shadows, overlays, header/transcript backgrounds, error states, and active tab/filter indicators. The token count grew from the planned ~30 to 77 because full coverage of the existing design required finer semantic distinctions — e.g., separate hover, focus, and subtle variants for the accent color, distinct badge background/text pairs for dark readability, and separate shadow weights for cards vs dialogs.\n\n**T02 — Mobile Responsive + HTML Metadata:** Added `overflow-x: hidden` to `html, body` as a global safety net against horizontal scroll. Fixed three specific overflow sources: mode-toggle label (added `overflow: hidden; text-overflow: ellipsis; max-width: 6rem`), creator-row stats (added `flex-wrap: wrap` in the 640px media query), and app-header__right (added `flex-wrap: wrap`). Updated index.html title from \"Chrysopedia Admin\" to \"Chrysopedia\" and added `<meta name=\"theme-color\" content=\"#0a0a12\">` for mobile browser chrome coloring. Deployed to ub01 and visually verified at desktop (1280×800) and mobile (390×844) viewports — dark theme renders correctly, no horizontal scrollbar on any tested page.\n\n## Verification\n\nAll slice-level verification checks pass:\n- `npm run build` exits 0 (clean build, no warnings)\n- Hex colors outside `:root` block: 0 (all 77 hex values are inside `:root` definitions only)\n- CSS `var(--` references: 217 (exceeds 190+ threshold)\n- `rgba()` outside `:root` block: 0\n- `overflow-x` rule present in App.css\n- `<title>Chrysopedia</title>` confirmed in index.html\n- `<meta name=\"theme-color\">` confirmed in index.html\n- Browser verification at 390px mobile viewport: scrollWidth === clientWidth (no horizontal overflow)\n- Visual verification on Home, Topics, and Creators pages at both desktop and mobile viewports confirms dark theme renders correctly\n\n## New Requirements Surfaced\n\nNone.\n\n## Deviations\n\nToken count grew from planned ~30 to 77 CSS custom properties — needed finer semantic granularity to fully eliminate all hardcoded colors. `.topic-category__count` has white-space:nowrap but didn't need fixing — text content is naturally short enough at 390px.\n\n## Known Limitations\n\nCreators page returns API 422 on ub01 — this is a pre-existing backend issue (addressed in S01), not caused by this slice. The CSS variables define a single dark theme; there is no light/dark toggle mechanism — the app is dark-only for now.\n\n## Follow-ups\n\nNone.\n\n## Files Created/Modified\n\n- `frontend/src/App.css` — Added 77 CSS custom properties in :root block, replaced all 193 hex colors and 24 rgba values with var(--*) references, added html/body overflow-x:hidden, fixed mode-toggle label truncation, creator-row stats wrapping, and header flex-wrap for mobile\n- `frontend/index.html` — Changed title from 'Chrysopedia Admin' to 'Chrysopedia', added <meta name=\"theme-color\" content=\"#0a0a12\">\n\n---\n\n### S02 UAT Result\nSource: `.gsd/milestones/M004/slices/S02/S02-UAT.md`\n\n# S02: Dark Theme + Cyan Accents + Mobile Responsive Fix — UAT\n\n**Milestone:** M004\n**Written:** 2026-03-30T06:42:29.412Z\n\n## UAT: Dark Theme + Cyan Accents + Mobile Responsive Fix\n\n### Preconditions\n- Chrysopedia frontend is deployed and accessible at http://ub01:8096\n- Browser dev tools available for viewport resizing\n\n---\n\n### Test 1: Dark Theme Renders on Desktop\n**Viewport:** 1280×800\n\n1. Navigate to http://ub01:8096\n2. **Expected:** Page background is near-black (#0f0f14), not white\n3. **Expected:** Header background is darker than page (#0a0a12)\n4. **Expected:** Cards (search results, nav cards) have dark surface backgrounds (#1a1a24), visually distinct from page\n5. **Expected:** Primary text is light (#e2e2ea), readable against dark backgrounds\n6. **Expected:** No white or light-gray backgrounds anywhere in the UI\n\n### Test 2: Cyan Accent Color\n**Viewport:** 1280×800\n\n1. Navigate to http://ub01:8096\n2. Hover over interactive elements (search button, nav cards)\n3. **Expected:** Accent color is cyan (#22d3ee), not indigo/purple\n4. **Expected:** Focus rings on form inputs are cyan\n5. **Expected:** Active tab/filter indicators use cyan\n6. Navigate to a technique page if available\n7. **Expected:** Links and interactive elements use cyan accent\n\n### Test 3: Status Badge Readability (if review queue accessible)\n**Viewport:** 1280×800\n\n1. Navigate to review queue (if accessible — may require /admin path)\n2. **Expected:** Status badges (pending, approved, edited, rejected) are visually distinct\n3. **Expected:** Badge text is readable — light text on dark tinted backgrounds\n4. **Expected:** Pending = amber text on dark amber bg, Approved = green text on dark green bg, Edited = blue text on dark blue bg, Rejected = red text on dark red bg\n\n### Test 4: No Horizontal Scroll on Mobile\n**Viewport:** 390×844 (iPhone 14 equivalent)\n\n1. Navigate to http://ub01:8096\n2. **Expected:** No horizontal scrollbar appears\n3. Try to scroll horizontally by dragging\n4. **Expected:** Page does not scroll horizontally\n5. **Expected:** All content fits within the 390px viewport width\n\n### Test 5: Header Wraps on Mobile\n**Viewport:** 390×844\n\n1. Navigate to http://ub01:8096\n2. Inspect the header area (logo, nav links, mode toggle)\n3. **Expected:** Header content wraps to multiple lines rather than overflowing\n4. **Expected:** Mode toggle label is truncated with ellipsis if too long, not pushing content off-screen\n\n### Test 6: Creators Page Mobile Layout\n**Viewport:** 390×844\n\n1. Navigate to Creators page\n2. **Expected:** Creator row stats (technique count, video count) wrap to next line instead of overflowing horizontally\n3. **Expected:** Genre filter pills wrap within the viewport\n4. **Expected:** No horizontal scroll on this page\n\n### Test 7: Topics Page Mobile Layout\n**Viewport:** 390×844\n\n1. Navigate to Topics page\n2. **Expected:** Topic categories and subcategories fit within viewport\n3. **Expected:** Count badges don't cause overflow\n4. **Expected:** No horizontal scroll on this page\n\n### Test 8: Search Input Mobile\n**Viewport:** 390×844\n\n1. Navigate to http://ub01:8096\n2. Tap/click the search input\n3. **Expected:** Search input fits within viewport width with appropriate padding\n4. **Expected:** No overflow caused by search form\n\n### Test 9: HTML Metadata\n1. View page source or inspect `<head>`\n2. **Expected:** `<title>` is \"Chrysopedia\" (not \"Chrysopedia Admin\")\n3. **Expected:** `<meta name=\"theme-color\" content=\"#0a0a12\">` is present\n4. On mobile browser: **Expected:** Browser chrome (status bar / address bar) matches dark header color\n\n### Test 10: No Hardcoded Colors in CSS Source\n1. Open `frontend/src/App.css`\n2. Search for hex color patterns outside the `:root` block\n3. **Expected:** Zero hex colors (#xxx, #xxxxxx) outside `:root`\n4. Search for `rgba(` outside the `:root` block\n5. **Expected:** Zero rgba() values outside `:root`\n6. Search for `var(--`\n7. **Expected:** 190+ occurrences (actual: 217)\n\n### Edge Cases\n- **Very long creator name:** Should truncate or wrap, not overflow on mobile\n- **Many genre filter pills:** Should wrap to multiple rows, not overflow\n- **Empty states:** Loading spinners and \"no results\" text should use theme colors, not white/black defaults\n\n---\n\n### S03 Summary\nSource: `.gsd/milestones/M004/slices/S03/S03-SUMMARY.md`\n\n---\nid: S03\nparent: M004\nmilestone: M004\nprovides:\n  - Technique detail API returns video_filename on each key moment\n  - Technique page renders meta stats, video sources, and signal chain flow blocks matching reference layout\nrequires:\n  - slice: S01\n    provides: Fixed technique detail endpoint (422 bug resolved)\naffects:\n  - S04\nkey_files:\n  - backend/schemas.py\n  - backend/routers/techniques.py\n  - frontend/src/api/public-client.ts\n  - frontend/src/pages/TechniquePage.tsx\n  - frontend/src/App.css\nkey_decisions:\n  - Populate video_filename via post-processing loop rather than Pydantic from_attributes auto-mapping, since the field comes from a joined relation not a direct column\n  - Used text-overflow ellipsis on video filename with max-width 20rem to prevent layout breakage on long filenames\npatterns_established:\n  - Chained selectinload for cross-relation field population in technique detail endpoint — pattern for adding more joined fields to API responses\nobservability_surfaces:\n  - none\ndrill_down_paths:\n  - .gsd/milestones/M004/slices/S03/tasks/T01-SUMMARY.md\n  - .gsd/milestones/M004/slices/S03/tasks/T02-SUMMARY.md\nduration: \"\"\nverification_result: passed\ncompleted_at: 2026-03-30T06:58:43.576Z\nblocker_discovered: false\n---\n\n# S03: Technique Page Redesign + Video Source on Moments\n\n**Technique detail pages now show meta stats, video filenames on key moments, and monospace signal chain flow blocks with arrow separators — matching the reference layout spec.**\n\n## What Happened\n\nThis slice delivered three visual changes to the technique page plus the backend data prerequisite to power them.\n\n**T01 (Backend):** Added `video_filename: str = \"\"` to the `KeyMomentSummary` Pydantic schema. Chained `.selectinload(KeyMoment.source_video)` onto the existing key_moments eager load in the technique detail endpoint. Added a post-processing loop that populates `video_filename` from the joined `source_video.filename` relation. Deployed to ub01 and verified all 13 key moments on the wave-shaping technique page return populated video filenames.\n\n**T02 (Frontend):** Three changes to TechniquePage.tsx plus corresponding CSS:\n1. **Meta stats line** below the title — shows source count (unique video filenames), moment count, and last-updated date. Computed inline via an IIFE for readability.\n2. **Video filename on key moments** — each moment row displays the source video filename in muted monospace text, truncated with ellipsis at 20rem to prevent layout breakage.\n3. **Signal chain flow blocks** — replaced the numbered `<ol>` list with a horizontal-wrap monospace `<div>` where steps are separated by cyan arrow (`→`) separators. Uses `var(--color-accent)` for the arrows, `var(--color-bg-surface)` background, and proper border-radius.\n\nAll CSS uses `var(--*)` tokens exclusively — zero hardcoded hex colors outside `:root`. The TypeScript `KeyMomentSummary` interface was updated to include `video_filename: string`. Build passes cleanly with zero errors.\n\n## Verification\n\n1. API returns video_filename on all key moments: `curl` to wave-shaping technique endpoint → 13 moments, all with `video_filename` populated as \"Skope - Understanding Waveshapers (2160p).mp4\".\n2. Frontend builds cleanly: `npm run build` exits 0 with zero TypeScript errors.\n3. No hardcoded colors: grep for hex colors outside `:root` returns zero matches.\n4. Live deployment on ub01:8096 serves the updated frontend with all three visual changes rendering correctly.\n\n## New Requirements Surfaced\n\nNone.\n\n## Deviations\n\nNone.\n\n## Known Limitations\n\nThe meta stats line computes source count client-side from video filenames — if two videos have the same filename (different paths), they'd be counted as one source. Unlikely in practice.\n\n## Follow-ups\n\nNone.\n\n## Files Created/Modified\n\n- `backend/schemas.py` — Added video_filename: str = '' to KeyMomentSummary schema\n- `backend/routers/techniques.py` — Chained selectinload for source_video; post-processing loop populates video_filename\n- `frontend/src/api/public-client.ts` — Added video_filename: string to KeyMomentSummary TypeScript interface\n- `frontend/src/pages/TechniquePage.tsx` — Added meta stats line, video filename display on moments, monospace signal chain flow blocks\n- `frontend/src/App.css` — Added CSS for technique-header__stats, technique-moment__source, technique-chain__flow/arrow/step classes\n\n---\n\n### S03 UAT Result\nSource: `.gsd/milestones/M004/slices/S03/S03-UAT.md`\n\n# S03: Technique Page Redesign + Video Source on Moments — UAT\n\n**Milestone:** M004\n**Written:** 2026-03-30T06:58:43.577Z\n\n## UAT: Technique Page Redesign + Video Source on Moments\n\n### Preconditions\n- Chrysopedia stack running on ub01 (all containers healthy)\n- At least one technique page exists with key moments and signal chains (e.g., wave-shaping-synthesis-m-wave-shaper)\n- Browser access to http://ub01:8096\n\n### Test 1: API returns video_filename on key moments\n\n1. Run: `curl -s http://ub01:8096/api/v1/techniques/wave-shaping-synthesis-m-wave-shaper | python3 -m json.tool`\n2. **Expected:** Each object in `key_moments` array has a `video_filename` field\n3. **Expected:** At least one moment has a non-empty `video_filename` value (e.g., \"Skope - Understanding Waveshapers (2160p).mp4\")\n4. **Expected:** All existing fields (title, summary, timestamp_start, etc.) are still present and unchanged\n\n### Test 2: Meta stats line renders below technique title\n\n1. Navigate to http://ub01:8096/techniques/wave-shaping-synthesis-m-wave-shaper\n2. **Expected:** Below the technique title, a stats line appears showing: \"Compiled from N source(s) · M key moment(s) · Last updated [date]\"\n3. **Expected:** Source count reflects unique video filenames (should be 1 for this technique — all moments from same video)\n4. **Expected:** Moment count matches the API response (13)\n5. **Expected:** Date is a readable format, not raw ISO timestamp\n\n### Test 3: Key moments show video filename\n\n1. On the same technique page, scroll to the key moments section\n2. **Expected:** Each key moment row displays the source video filename in smaller muted text\n3. **Expected:** Long filenames are truncated with ellipsis (not wrapping or overflowing)\n4. **Expected:** Moments without a video filename (if any) do not show an empty label\n\n### Test 4: Signal chains render as monospace flow blocks\n\n1. On the same technique page, scroll to the signal chains section\n2. **Expected:** Each signal chain renders as a horizontal flow of steps separated by cyan `→` arrows\n3. **Expected:** Steps use monospace-style font\n4. **Expected:** The flow block has a subtle background (surface color) with padding and rounded corners\n5. **Expected:** Steps wrap naturally on narrow viewports without breaking mid-step\n\n### Test 5: No hardcoded colors in CSS\n\n1. Run: `grep -P '#[0-9a-fA-F]{3,8}' frontend/src/App.css` and inspect results\n2. **Expected:** All hex color values appear only within the `:root { }` block\n3. **Expected:** Zero hex colors in any class definition outside `:root`\n\n### Test 6: Frontend builds with zero errors\n\n1. Run: `cd frontend && npm run build`\n2. **Expected:** Build succeeds with exit code 0\n3. **Expected:** No TypeScript errors in output\n\n### Edge Cases\n\n- **Technique with no key moments:** Meta stats should show \"0 key moments\" and \"0 sources\"\n- **Technique with no signal chains:** Signal chains section should not render (or render empty gracefully)\n- **Moment with empty video_filename:** Video filename label should not appear for that moment\n\n---\n\n### S04 Summary\nSource: `.gsd/milestones/M004/slices/S04/S04-SUMMARY.md`\n\n---\nid: S04\nparent: M004\nmilestone: M004\nprovides:\n  - TechniquePageVersion model and migration\n  - Version list/detail API endpoints\n  - Pipeline metadata capture helper (_capture_pipeline_metadata)\n  - Frontend version count display and fetchTechniqueVersions API function\nrequires:\n  []\naffects:\n  []\nkey_files:\n  - backend/models.py\n  - alembic/versions/002_technique_page_versions.py\n  - backend/pipeline/stages.py\n  - backend/schemas.py\n  - backend/routers/techniques.py\n  - backend/tests/test_public_api.py\n  - frontend/src/api/public-client.ts\n  - frontend/src/pages/TechniquePage.tsx\nkey_decisions:\n  - D018: Best-effort versioning — snapshot INSERT failure logs ERROR but does not block page update\n  - Composite unique index on (technique_page_id, version_number) enforces version ordering at DB level\n  - Version count only displayed in frontend when > 0 to avoid clutter on pages with no history\n  - source_quality enum stored as string .value in JSONB snapshot for serialization compatibility\npatterns_established:\n  - Pre-overwrite snapshot pattern: before mutating an existing DB row, capture its current state into a version table with pipeline metadata for audit/benchmarking\n  - _capture_pipeline_metadata() helper collects prompt file hashes + model config — reusable for any pipeline stage that needs reproducibility metadata\nobservability_surfaces:\n  - INFO log in stage 5 when version snapshot is created (includes version_number and page slug)\n  - ERROR log if snapshot INSERT fails (with exception details)\n  - SELECT * FROM technique_page_versions ORDER BY created_at DESC LIMIT 5 — inspect recent versions\n  - GET /techniques/{slug}/versions — API surface for version history\ndrill_down_paths:\n  - .gsd/milestones/M004/slices/S04/tasks/T01-SUMMARY.md\n  - .gsd/milestones/M004/slices/S04/tasks/T02-SUMMARY.md\n  - .gsd/milestones/M004/slices/S04/tasks/T03-SUMMARY.md\nduration: \"\"\nverification_result: passed\ncompleted_at: 2026-03-30T07:21:14.192Z\nblocker_discovered: false\n---\n\n# S04: Article Versioning + Pipeline Tuning Metadata\n\n**Added technique page version tracking with pipeline metadata capture, snapshot-on-write in stage 5, version list/detail API endpoints, and frontend version count display.**\n\n## What Happened\n\nThis slice added a full article versioning stack across all three layers — database model, API, and frontend.\n\n**T01 (Model + Migration + Pipeline Hook):** Added `TechniquePageVersion` model with UUID PK, FK to technique_pages (CASCADE delete), version_number, content_snapshot (JSONB), pipeline_metadata (JSONB), and created_at.

Wrote 6 integration tests covering empty list, populated list ordering, detail with snapshot content, 404 for missing version, 404 for missing slug, and version_count on technique detail. All pass alongside 8 pre-existing tests.\n\n**T03 (Frontend):** Added TypeScript interfaces mirroring the backend schemas, a fetchTechniqueVersions API function, and conditional version count display in TechniquePage meta stats (only when > 0). Frontend builds with zero TypeScript errors.\n\n## Verification\n\nAll slice-level verification checks pass:\n1. `cd backend && python -c \"from models import TechniquePageVersion; print('Model OK')\"` → exit 0\n2. `test -f alembic/versions/002_technique_page_versions.py` → exit 0\n3. `grep -q '_capture_pipeline_metadata' backend/pipeline/stages.py` → exit 0\n4. `grep -q 'TechniquePageVersion' backend/pipeline/stages.py` → exit 0\n5. `cd backend && python -c \"from schemas import TechniquePageVersionSummary, TechniquePageVersionDetail, TechniquePageVersionListResponse\"` → exit 0\n6. `cd frontend && npm run build` → exit 0, zero errors\n7. `grep -q 'version_count' frontend/src/api/public-client.ts && grep -q 'version_count' frontend/src/pages/TechniquePage.tsx && grep -q 'fetchTechniqueVersions' frontend/src/api/public-client.ts` → exit 0\n\n## New Requirements Surfaced\n\nNone.\n\n## Deviations\n\nNone.\n\n## Known Limitations\n\n1. Version list endpoint returns all versions without pagination — acceptable since version count per page is expected to be small (single-digit to low tens).\n2. Backend integration tests require PostgreSQL on ub01:5433 and cannot run locally on this machine.\n3. Pre-existing creator test failures (5 tests) and test_search.py deadlock issues exist but are unrelated to versioning.\n4. Pipeline metadata capture hashes prompt files at snapshot time — if prompt files are deleted or moved, the hash will be empty (logged as WARNING).\n\n## Follow-ups\n\nNone.\n\n## Files Created/Modified\n\n- `backend/models.py` — Added TechniquePageVersion model with UUID PK, FK, version_number, content_snapshot (JSONB), pipeline_metadata (JSONB), created_at. Added versions relationship on TechniquePage.\n- `alembic/versions/002_technique_page_versions.py` — New migration creating technique_page_versions table with composite unique index on (technique_page_id, version_number)\n- `backend/pipeline/stages.py` — Added _capture_pipeline_metadata() helper and pre-overwrite snapshot logic in stage5_synthesis\n- `backend/schemas.py` — Added TechniquePageVersionSummary, TechniquePageVersionDetail, TechniquePageVersionListResponse schemas; added version_count to TechniquePageDetail\n- `backend/routers/techniques.py` — Added GET /{slug}/versions and GET /{slug}/versions/{version_number} endpoints; modified get_technique to include version_count\n- `backend/tests/test_public_api.py` — Added 6 integration tests for version endpoints\n- `frontend/src/api/public-client.ts` — Added version_count to TechniquePageDetail, TechniquePageVersionSummary/ListResponse interfaces, fetchTechniqueVersions function\n- `frontend/src/pages/TechniquePage.tsx` — Conditional version count display in meta stats line\n\n---\n\n### S04 UAT Result\nSource: `.gsd/milestones/M004/slices/S04/S04-UAT.md`\n\n# S04: Article Versioning + Pipeline Tuning Metadata — UAT\n\n**Milestone:** M004\n**Written:** 2026-03-30T07:21:14.192Z\n\n## UAT: S04 — Article Versioning + Pipeline Tuning Metadata\n\n### Preconditions\n- PostgreSQL running on ub01:5433 with chrysopedia database\n- Alembic migration 002 applied (`docker exec chrysopedia-api alembic upgrade head`)\n- At least one technique page exists in the database (from prior pipeline runs)\n- API running at ub01:8096\n- Frontend built and served\n\n---\n\n### Test 1: TechniquePageVersion model loads correctly\n**Steps:**\n1. `docker exec chrysopedia-api python -c \"from models import TechniquePageVersion; print('OK')\"`\n\n**Expected:** Prints \"OK\", exit 0.\n\n---\n\n[...truncated 31 sections]\n\n\n\n## Validation Steps\n\n1. For each **success criterion** in `.gsd/milestones/M004/M004-ROADMAP.md`, check whether slice summaries and UAT results provide evidence that it was met. Record pass/fail per criterion.\n2. For each **slice** in the roadmap, verify its demo/deliverable claim against its summary. Flag any slice whose summary does not substantiate its claimed output.\n3. Check **cross-slice integration points** — do boundary map entries (produces/consumes) align with what was actually built?\n4. Check **requirement coverage** — are all active requirements addressed by at least one slice?\n5. If **Verification Classes** are provided in the inlined context above, check each non-empty class:\n   - For each verification class (Contract, Integration, Operational, UAT), determine whether slice summaries, UAT results, or observable behavior provide evidence that this verification tier was addressed.\n   - Document the compliance status of each class in a dedicated verification classes section.\n   - If `Operational` verification is non-empty and no evidence of operational verification exists, flag this explicitly — it means planned operational checks (migrations, deployments, runtime verification) were not proven.\n   - A milestone with unaddressed verification classes may still pass if the gaps are minor, but the gaps MUST be documented in the Deferred Work Inventory.\n6. Determine a verdict:\n   - `pass` — all criteria met, all slices delivered, no gaps\n   - `needs-attention` — minor gaps that do not block completion (document them)\n   - `needs-remediation` — material gaps found; remediation slices must be added to the roadmap\n\n## Persist Validation\n\n**Persist validation results through `gsd_validate_milestone`.** Call it with: `milestoneId`, `verdict`, `remediationRound`, `successCriteriaChecklist`, `sliceDeliveryAudit`, `crossSliceIntegration`, `requirementCoverage`, `verificationClasses` (when non-empty), `verdictRationale`, and `remediationPlan` (if verdict is `needs-remediation`). The tool writes the validation to the DB and renders VALIDATION.md to disk.\n\nIf verdict is `needs-remediation`:\n- After calling `gsd_validate_milestone`, use `gsd_reassess_roadmap` to add remediation slices. Pass `milestoneId`, a synthetic `completedSliceId` (e.g. \"VALIDATION\"), `verdict: \"roadmap-adjusted\"`, `assessment` text, and `sliceChanges` with the new slices in the `added` array. The tool persists the changes to the DB and re-renders ROADMAP.md.\n- These remediation slices will be planned and executed before validation re-runs.\n\n**File system safety:** When scanning milestone directories for evidence, use `ls` or `find` to list directory contents first — never pass a directory path (e.g. `tasks/`, `slices/`) directly to the `read` tool. The `read` tool only accepts file paths, not directories.\n\nWhen done, say: \"Milestone M004 validation complete — verdict: <verdict>.\"","display":false,"id":"83ea98f1","parentId":"b5c98d33","timestamp":"2026-03-30T07:21:36.703Z"}

Frontend builds cleanly. ✅\n- S04: 6 integration tests pass (version list, detail, 404s, version_count). ✅\n- **Status: SATISFIED**\n\n**Integration** (\"Real pipeline data renders correctly in redesigned pages\"):\n- S01: Verified with 72 real key moments from pipeline data on ub01. ✅\n- S03: Verified with wave-shaping technique page (13 moments, real video filename). ✅\n- S04: Integration tests run against PostgreSQL with real schema. ✅\n- **Status: SATISFIED**\n\n**Operational** (\"Alembic migration applies on ub01, version history persists across pipeline re-runs\"):\n- S01/S02/S03: All deployed to ub01 via docker compose build + up. ✅\n- S04: Migration 002 created and tested in integration tests. However, no explicit evidence that `alembic upgrade head` was run on ub01 production DB, or that version history persists after a second pipeline run.\n- **Status: PARTIALLY SATISFIED** — Migration exists and is tested, but operational deployment proof on ub01 is not explicitly documented.
