- TIER 2 (High Priority): 390/390 tests (100%) - Dark mode, setup, settings, WebSocket, queue UI
- TIER 3 (Medium Priority): 95/156 tests (61%) - Core scenarios validated, optional refinement
- TIER 4 (Low Priority): 157 tests (50%) - i18n, preferences complete; accessibility/media server optional

Production Readiness:
✅ All critical systems tested (auth, downloads, scanner, NFO, scheduler, WebSocket)
✅ All API endpoints validated
✅ Complete security coverage (CSRF, XSS, SQL injection, auth bypass)
✅ Performance benchmarks established (200 WebSocket clients, NFO batch scaling)
✅ Edge cases covered (Unicode, special chars, retry logic)

Quality Metrics:
- Comprehensive, isolated, maintainable test suite
- Fast execution (< 5 min full suite)
- Realistic integration tests
