+- [x] **T02: Removed yellow semantic-search-unavailable banner from search results, simplified footer to hide commit info in dev builds, and bumped version to 0.8.0** — Three independent frontend cleanups:
 1. Remove the yellow 'semantic search unavailable' fallback banner from SearchResults
 2. Clean up the footer to hide commit info when value is 'dev' (already partially done — verify and simplify)
 3. Bump package.json version to 0.8.0

+
+**Removed yellow semantic-search-unavailable banner from search results, simplified footer to hide commit info in dev builds, and bumped version to 0.8.0**
+
+## What Happened
+
+Three independent frontend cleanups: (1) removed fallback banner JSX and CSS rule plus the now-unused fallbackUsed state variable, (2) simplified AppFooter to conditionally hide commit section when __GIT_COMMIT__ is 'dev' instead of showing plain 'dev' text, (3) bumped package.json version to 0.8.0. Build passes with zero errors.
+
+## Verification
+
+All grep checks pass (no banner references remain), version confirmed as 0.8.0, npm run build succeeds with zero errors. Slice-level Creator model check also passes.
+
+## Verification Evidence
+
+| # | Command | Exit Code | Verdict | Duration |
+|---|---------|-----------|---------|----------|
+| 1 | `grep -q 'search-fallback-banner' frontend/src/pages/SearchResults.tsx` | 1 | ✅ pass (not found) | 100ms |
+| 2 | `grep -q 'search-fallback-banner' frontend/src/App.css` | 1 | ✅ pass (not found) | 100ms |
+| 3 | `grep -q '"0.8.0"' frontend/package.json` | 0 | ✅ pass | 100ms |
+| 4 | `cd frontend && npm run build` | 0 | ✅ pass | 2600ms |
+
+
+## Deviations
+
+Removed fallbackUsed state variable entirely — TS strict mode flagged it as unused after banner JSX removal, causing build failure. Plan said to keep it.
+
+## Known Issues
+
+None.
