# T03: Built frontend search flow: typed public API client, landing page with debounced typeahead, search results with grouped display, and full technique page with prose/key moments/signal chains/plugins/related links

**Built frontend search flow: typed public API client, landing page with debounced typeahead, search results with grouped display, and full technique page with prose/key moments/signal chains/plugins/related links**

## What Happened

Created public-client.ts with typed interfaces for all backend schemas and 6 endpoint functions. Built Home.tsx with auto-focused search bar, 300ms debounced typeahead (top 5 after 2+ chars), nav cards for Topics/Creators, and Recently Added section. Built SearchResults.tsx with URL param-driven search, type-grouped results (techniques first, then key moments), and keyword fallback banner. Built TechniquePage.tsx with full detail rendering: header with badges/tags/creator link, amber banner for unstructured content, body_sections prose, key moments index, signal chains, plugins pill list, related techniques. Updated App.tsx with public + admin routes and new navigation. Extended App.css with ~500 lines for all new components.

## Verification

TypeScript strict compilation passes with zero errors. Production build succeeds (40 modules, 191KB JS). All 4 expected page files exist. All 5 slice verification checks pass. Backend tests: 18/18 search+public API tests pass, 58/58 full suite passes with zero regressions.

## Verification Evidence

| # | Command | Exit Code | Verdict | Duration |
|---|---------|-----------|---------|----------|
| 1 | `cd frontend && npx tsc -b` | 0 | ✅ pass | 2500ms |
| 2 | `cd frontend && npm run build` | 0 | ✅ pass | 3400ms |
| 3 | `test -f frontend/src/api/public-client.ts && test -f frontend/src/pages/Home.tsx && test -f frontend/src/pages/SearchResults.tsx && test -f frontend/src/pages/TechniquePage.tsx` | 0 | ✅ pass | 50ms |
| 4 | `cd backend && python -m pytest tests/test_search.py tests/test_public_api.py -v` | 0 | ✅ pass | 10600ms |
| 5 | `cd backend && python -m pytest tests/ -v` | 0 | ✅ pass | 142900ms |


## Deviations

The verification failures that triggered this auto-fix attempt were caused by running test commands from the project root instead of from the backend/ directory. The test files exist at backend/tests/ and pass correctly.

## Known Issues

None.
