 Follows patterns from `AdminPipeline.tsx` (table layout, expandable rows, badges, fetch pattern).

+
+**Built AdminTechniquePages page at /admin/techniques with table, expandable source video rows, filters, format badges, and admin dropdown entry**
+
+## What Happened
+
+Added AdminTechniquePageItem interface and fetchAdminTechniquePages function to public-client.ts matching the backend schema from T01. Created AdminTechniquePages.tsx with a table showing title, creator, category, format badge (v1/v2), source count, version count, and updated date. Rows expand on click to show source videos fetched from the existing technique detail endpoint, with links to pipeline admin via video ID query param. Filter bar includes multi-source-only checkbox, creator text filter, and sort dropdown. Added /admin/techniques route in App.tsx and Techniques entry in AdminDropdown.tsx. Deployed to ub01 and verified in browser.
+
+## Verification
+
+Frontend build passes clean (tsc + vite, 0 errors). Schema import verified via docker exec. API endpoint returns valid JSON with 20 pages. Browser verification: page renders table with all columns, row expansion works showing source videos section, admin dropdown shows all three entries (Reports, Pipeline, Techniques).
+
+## Verification Evidence
+
+| # | Command | Exit Code | Verdict | Duration |
+|---|---------|-----------|---------|----------|
+| 1 | `cd frontend && npm run build` | 0 | ✅ pass | 3000ms |
+| 2 | `docker exec chrysopedia-api python -c 'from schemas import AdminTechniquePageItem; print(AdminTechniquePageItem.model_fields.keys())'` | 0 | ✅ pass | 1000ms |

+
+
+## Deviations
+
+None.
+
+## Known Issues
+
+Source video and version counts are all 0 because association tables are empty. UI displays correctly and will show real counts when populated.
