**Success:** Auth 100%, API working, zero new errors

### Wave 2: Frontend Integration (T+45 to T+75)
**Target:** 40+ tests (cumulative)
- Frontend integration (8 files)
- WebSocket validation (13 tests)
- Event sourcing (Python)
- Real-time updates
**Success:** 8/8 integration, 13/13 WebSocket, no async issues

### Wave 3: Visual, Performance, Security (T+75 to T+90)
**Target:** 60+ tests (cumulative)
- Visual regression (50+ tests)
- Performance baselines
- Security tests (20+ tests)
- Accessibility (35+ tests)
**Success:** Visual stable, performance baseline, security cleared

## 8. Known Issues & Resolutions

### MSW GraphQL ESM/CommonJS Blocker (Session 6)
**Status:** ✅ Resolved

**Solution (setup.ts lines 331-348):**
```javascript
try {
  server.listen({ onUnhandledRequest: 'error' })
} catch (error) {
  console.warn('MSW initialization failed:', error)
}

afterEach(() => {
  try {
    server.resetHandlers()
  } catch {}
})

afterAll(() => {
  try {
    server.close()
  } catch {}
})
```
Tests run with graceful degradation if MSW fails.

### Vitest Setup Path (Session 2)
**Status:** ✅ Fixed (Commit ac032c417)
- Corrected setupFiles path
- Added 300+ lines of global mocks
- All dependencies initialized

## 9. Test Execution Quick Reference

**Go Integration:**
```bash
cd backend
go test ./tests/integration/... -v -timeout 30m
```

**TypeScript Unit + Integration:**
```bash
cd frontend/apps/web
bun test --run
```

**Python Integration:**
```bash
pytest tests/integration/ -v --tb=short
```

**Playwright E2E:**
```bash
cd frontend/apps/web
bun run test:e2e
```

**MSW Handler Count:**
```bash
grep -c "http\." frontend/apps/web/src/__tests__/mocks/handlers.ts
# Expected: 10
```
