## QUALITY ASSURANCE

### Pre-Commit Verification ✅
- Phase 5.1-5.2: 18 tests confirmed passing
- Phase 5.3-5.5: 15+ tests confirmed passing

- No breaking changes introduced
- No new compilation errors

### Test Validation ✅
- Backend auth tests: PASS (go test ./internal/auth)
- Frontend handlers: Working (MSW +25 lines)
- Router mocks: Integrated (setup.ts updated)
- App-integration tests: Enabled and passing

### Known Issues (Pre-existing) ⚠️
- Backend service tests: 3 failures (pre-existing, not Phase 5)
  - Storage service upload panic
  - Storybook error message mismatch
  - Temporal build failure
- **Resolution:** These are blocking on backend refactoring, not Phase 5
