# Milestone Validation: M006

## Success Criteria Checklist
## Success Criteria Checklist

- [x] **Admin links consolidated under dropdown** — S01 delivered AdminDropdown.tsx with Review Queue, Reports, Pipeline links. Deployed bundle contains `admin-dropdown` classes. Header shows Home/Topics/Creators as flat links + Admin dropdown.
- [x] **Pipeline event log has head/tail toggle** — S02 added `order=asc|desc` query param to backend + Head/Tail segmented toggle in frontend. `curl ?order=invalid` returns 400. Default `desc` preserved for backward compat.
- [x] **Git commit SHA appears in version metadata** — S03 added 4-tier SHA resolution chain in `_get_git_commit_sha()`, Dockerfile.api build arg, and conditional Commit row in TechniquePage.tsx. Currently shows "unknown" on pre-rebuild containers (expected); code verified on ub01 (3 matches in stages.py, 1 in config.py).
- [x] **Technique page sidebar reordered with plugins first** — S04 moved Plugins Referenced to top of sidebar div. Creator block added between h1 and meta row with genre pills.
- [x] **Tags use coherent color scheme** — S04 added 6 per-category badge color pairs (sound-design, mixing, synthesis, arrangement, workflow, mastering) as CSS custom properties + utility classes. 7 `badge--cat-*` classes in App.css (6 original + music-theory from S05).
- [x] **Topics page shows 7 categories with Music Theory** — S05 added Music Theory with 8 sub-topics to canonical_tags.yaml. Live API returns 7 categories confirmed. Topics page redesigned as 2-column responsive card grid.
- [x] **Footer shows version info** — S06 delivered AppFooter with version (0.1.0), build date, commit SHA, GitHub link. Deployed bundle contains `0.1.0`. Footer pushed to bottom via flex-column + min-height:100vh.

## Slice Delivery Audit
## Slice Delivery Audit

| Slice | Claimed Deliverable | Evidence | Verdict |
|-------|-------------------|----------|---------|
| S01 | Admin dropdown with Review/Reports/Pipeline; ModeToggle removed from header | AdminDropdown.tsx exists, 6 `admin-dropdown` hits in deployed bundle, App.tsx updated | ✅ Delivered |
| S02 | Head/Tail toggle for event log; token counts visible | Backend `order` param verified (400 on invalid), frontend segmented toggle (7 matches in AdminPipeline.tsx), API confirmed order=asc/desc working | ✅ Delivered |
| S03 | Git commit SHA captured at build time and shown in version metadata | `_get_git_commit_sha()` on ub01 (3 matches), `git_commit_sha` in config.py, conditional Commit row in TechniquePage.tsx, Dockerfile.api build arg | ✅ Delivered |
| S04 | Sidebar reordered (plugins first), creator emphasis, per-category badge colors | Plugins at line 418 (first in sidebar), creator-block at line 230, 7 badge--cat-* classes in CSS, dynamic category class in JSX | ✅ Delivered |
| S05 | Topics page redesign with 7 categories including Music Theory | API returns 7 categories (confirmed live), TopicsBrowse.tsx rewritten with topics-grid layout, canonical_tags.yaml updated, music-theory badge CSS added | ✅ Delivered |
| S06 | App footer with version, build date, commit SHA, repo link | AppFooter.tsx exists, Vite define config with 3 build-time constants, deployed bundle contains 0.1.0, flex-column layout applied | ✅ Delivered |

## Cross-Slice Integration
## Cross-Slice Integration

**S03 → S06 interaction:** Both slices deal with git commit SHA. S03 captures it backend-side for pipeline metadata. S06 captures it frontend-side for the footer. They use different mechanisms: S03 uses a 4-tier Python fallback chain reading `.git-commit` file or git binary; S06 uses Vite build-time constants from `execSync('git rev-parse')` or `VITE_GIT_COMMIT` env var. Both receive the SHA via the shared `GIT_COMMIT_SHA` docker-compose build arg. The S06 summary correctly notes this dependency and the pattern match.

**S04 → S05 badge colors:** S04 established the per-category badge color system (6 categories). S05 extended it with a 7th color (music-theory: warm orange-gold). App.css now has 7 `badge--cat-*` classes. No conflicts — the patterns are additive and consistent.

**No boundary mismatches detected.** All slices are independent with clean handoffs where they overlap.

## Requirement Coverage
## Requirement Coverage

M006 is a polish/UX milestone. Active requirements are R001–R015 (R015 is the only `active` one; all others are `validated`).

**Requirements advanced:**
- **R006 (Technique Page Display)** — Advanced by S04: sidebar reordered for usability, creator given visual prominence, category badges color-coded per category.
- **R008 (Topics Browse Page)** — Advanced by S05: upgraded from 6 categories to 7 (Music Theory added), redesigned from accordion to responsive card grid with descriptions, stats, and color-coded accents.

**R015 (30-Second Retrieval Target)** — Active but not in scope for M006. This is a UX performance target that applies to the overall system; M006's changes (better sidebar ordering, better topics navigation) indirectly support it but don't explicitly validate it.

**No active requirements left unaddressed that were in-scope for M006.** M006's scope was explicitly polish/UX improvements, not new feature requirements.

## Verification Class Compliance
## Verification Classes

### Contract ✅
All 7 contract items verified:
1. Admin links consolidated under dropdown — AdminDropdown.tsx deployed with 3 links ✅
2. Pipeline event log has head/tail toggle — API `order` param + frontend toggle ✅
3. Git commit SHA in version metadata — 4-tier fallback chain + conditional UI row ✅
4. Technique page sidebar reordered (plugins first) — Code confirmed ✅
5. Tags use coherent color scheme — 7 per-category badge color pairs in CSS ✅
6. Topics page shows 7 categories with Music Theory — Live API returns 7 ✅
7. Footer shows version info — Deployed bundle contains 0.1.0 ✅

### Integration ✅
1. Admin dropdown navigates to all three admin pages — S01 uses React Router Links to /admin/review, /admin/reports, /admin/pipeline ✅
2. Pipeline events API returns correct data with head/tail — order=asc returns ascending timestamps, order=desc returns descending, order=invalid returns 400 ✅
3. Version metadata capture includes real git SHA — Code verified on ub01; currently "unknown" on pre-rebuild containers (expected, documented) ✅
4. Topics API returns 7 categories from updated canonical_tags.yaml — Confirmed live: Sound Design, Mixing, Synthesis, Arrangement, Workflow, Mastering, Music Theory ✅

### Operational ⚠️ (minor gap)
1. Frontend builds with zero TypeScript errors — `npx tsc --noEmit` exit 0, `npx vite build` exit 0 ✅
2. All containers healthy on ub01 — All 7 containers Up and (healthy) confirmed ✅
3. No console errors on any page — **Not explicitly verified.** No browser-based console error check was performed. Slice summaries don't report console errors but no systematic scan was done.
4. Footer version displays correctly — Deployed bundle contains "0.1.0" ✅

**Gap:** No systematic browser console error check across all pages. This is a minor gap — all slices passed their individual build/deploy verifications and no errors were reported, but a targeted console-error sweep was not performed.

### UAT ⚠️ (documented, not blocking)
UAT test cases were written for all 6 slices. These are manual verification scripts. No automated UAT execution occurred — the UAT.md files serve as test plans for manual verification. Slice summaries provide partial UAT coverage through their individual verification steps (e.g., S05 verified desktop 2-column grid, mobile 1-column layout, filter, expand/collapse via browser).


## Verdict Rationale
All 6 slices delivered their claimed outputs. All 7 success criteria met with evidence from deployed code, live API responses, and build verification. Cross-slice integration is clean. Two minor gaps exist: (1) no systematic browser console error sweep across all pages, and (2) UAT test plans exist but weren't formally executed as automated tests. Neither gap is material — all individual slice verifications passed, all containers are healthy, and the deployed bundle contains all expected artifacts. These gaps are documented for the record but do not warrant remediation slices.
