# Milestone Validation: M010

## Success Criteria Checklist
## Success Criteria (derived from Vision + Slice "After this" claims)

- [x] **Sub-topic pages with grouped content and breadcrumbs** — S01 delivers `/topics/:category/:subtopic` route, backend endpoint with ARRAY contains matching, breadcrumb nav, creator-grouped technique listings. Build and tests pass. **PASS**
- [x] **Related techniques on every technique page** — S02 delivers dynamic scoring (creator overlap + category match + shared tags), up to 4 results, responsive card grid. Build and tests pass. **PASS**
- [x] **7 topic categories with distinct accent colors** — S03 delivers per-category accent colors on SubTopicPage (border + badge) and SearchResults (badge), using CSS custom properties from M004/S02. Build passes. **PASS**
- [x] **Page transitions smooth** — S03 delivers `@keyframes pageEnter` fade-in (250ms ease-out) on all 7 public page wrapper classes via CSS selector list. No TSX changes needed. **PASS**
- [ ] **Creator avatars visually unique** — S03 roadmap "After this" claims this but neither S03 summary nor any task summary mentions creator avatar work. **NOT DELIVERED** (minor — cosmetic detail, no functional impact)
- [x] **Search autocomplete with suggestions** — S04 delivers `GET /api/v1/search/suggestions` (top techniques, tags, creators), `SearchAutocomplete` shared component with popular suggestions on focus and debounced typeahead on 2+ chars. Build and tests pass. **PASS**
- [x] **User discovers related techniques naturally** — S02 exploration loop (read technique → see related → click → new technique) is structurally complete. S01 sub-topic pages provide another discovery axis. **PASS**

## Slice Delivery Audit
| Slice | Claimed Deliverable | Evidence | Verdict |
|-------|---------------------|----------|---------|
| S01 | Clicking sub-topic loads /topics/mixing/compression with techniques grouped by creator, breadcrumbs | SubTopicPage.tsx, backend endpoint, breadcrumb CSS, 3 integration tests pass, build clean | ✅ Delivered |
| S02 | Bottom of every technique page shows 3-4 related techniques from same creator or sub-topic | Dynamic scoring helper, RelatedLinkItem schema enrichment, responsive card grid, 4 integration tests pass, build clean | ✅ Delivered |
| S03 | 7 categories with distinct accent colors, smooth page transitions, visually unique creator avatars | Accent colors on SubTopicPage + SearchResults, pageEnter animation on 7 pages. **Creator avatars NOT addressed** — no code, no tests, no summary mention | ⚠️ Partially delivered (creator avatars missing) |
| S04 | Autocomplete suggestions on typing, popular terms on empty focus | Backend suggestions endpoint (12 items, 3 types), SearchAutocomplete component, 5 integration tests pass, build clean | ✅ Delivered |

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

**S03 → S01 dependency:** S03 consumed S01's SubTopicPage component and `.subtopic-page` CSS class to apply category accent border and badge. Confirmed in S03 summary `requires` field. ✅

**S02 → S03 affects:** S03 did not explicitly consume S02 output. S03's color work targeted SubTopicPage and SearchResults, independent of S02's related techniques cards. No integration issue — the related cards on TechniquePage use their own `.related-card` styles from S02. ✅

**S04 independent:** S04 had no declared dependencies and built independently. SearchAutocomplete replaced inline logic in Home.tsx and SearchResults.tsx. No conflict with S03's SearchResults badge changes — S03 touches result card badges, S04 touches the search input component. ✅

**No boundary mismatches detected.** All `provides`/`requires` align with actual implementation.

## Requirement Coverage
## Requirement Coverage

**R008 (Topics Browse Page)** — Status: validated. Advanced by S01: sub-topics now have dedicated pages (`/topics/:category/:subtopic`) with structured content instead of search redirects. Meets the "Clicking sub-topic shows technique pages" validation criterion at a higher quality level.

**R005 (Search-First Web UI)** — Status: validated. Advanced by S04: autocomplete suggestions (popular terms on empty focus, typeahead on 2+ chars) enhance the search experience on both Home and SearchResults pages.

**R015 (30-Second Retrieval Target)** — Status: active. Advanced by S04: autocomplete reduces keystrokes needed to find techniques. No formal timed test conducted — R015 remains active, not validated.

**No requirements left unaddressed** for this milestone's scope. R015 was appropriately advanced but not validated (requires manual timed testing).

## Verification Class Compliance
## Verification Class Compliance

### Contract
- Sub-topic pages render with grouped content → **Verified.** S01 build passes, 3 integration tests confirm endpoint returns grouped technique data.
- Related techniques are relevant (shared tags) → **Verified.** S02 scoring algorithm tested with 4 integration tests covering ranking, self-exclusion, no-peers, NULL tags.
- Colors pass contrast checks → **Not explicitly verified.** S03 reuses CSS custom properties from M004/S02 (established palette), but no WCAG contrast audit was performed on the new accent border/badge combinations. **Minor gap.**

### Integration
- Sub-topic routes resolve correctly → **Verified.** S01 backend tests (happy path, empty results, pagination) pass against PostgreSQL.
- Related technique queries return meaningful results → **Verified.** S02 tests confirm scoring correctness and ranking.
- Search suggestions return quickly → **Partially verified.** S04 endpoint tested for correctness (5 tests pass). No explicit latency measurement. **Minor gap.**

### Operational
- All new routes healthy → **Not verified against deployed stack.** S01/S02/S04 summaries note Docker images on ub01 need rebuild to pick up new code. No evidence of post-deployment route health checks. **Gap — deferred to deployment.**
- No 404s for sub-topic pages → **Not verified against deployed stack.** Same deployment gap. **Deferred.**

### UAT
- UAT test scripts written for all 4 slices → **Written.** All S01-S04 have comprehensive UAT documents with preconditions, test steps, and expected results.
- UAT execution evidence → **No recorded execution results.** UAT documents are test plans, not test reports. Execution deferred to deployment. **Gap — noted.**


## Verdict Rationale
**Verdict: needs-attention.** All four slices delivered their core functionality — sub-topic pages, related techniques, color coding, and search autocomplete are built, type-checked, and integration-tested. Three minor gaps exist: (1) S03 roadmap claimed "creator avatars are visually unique" but no avatar work was done — this is a cosmetic detail from the demo text, not a functional requirement; (2) operational verification against the deployed ub01 stack was not performed — images need rebuild; (3) UAT documents are written as test plans but no execution evidence is recorded. None of these gaps are material enough to block milestone completion — they represent deployment-time work and a cosmetic stretch feature, not missing functionality.
