- **Coverage**: Directory created, ready for generation
- **Linting**: 182 files auto-fixed, remaining issues need review
- **Type Checking**: ✅ Passing

### Backend
- **Compilation**: ✅ All packages compile
- **Test Status**: ✅ All unit tests pass
- **Coverage**:
  - `internal/embeddings`: 44.8%
  - `internal/handlers`: 35.9%
  - `internal/infrastructure`: 30.1%
  - `internal/nats`: 21.8%
  - Overall: 37.9%

## 🎯 Integration Tests Status

All integration test files created with proper structure:
- ✅ `search_integration_test.go`
- ✅ `graph_integration_test.go`
- ✅ `queries_integration_test.go`
- ✅ `repository_integration_test.go`

**Note**: Integration tests require:
1. Running with `-tags=integration` flag
2. Docker available for testcontainers
3. Migrations to be run in test database

## ✅ Verification

### Backend Tests
```bash
cd backend
go test ./internal/embeddings/...     # ✅ PASS
go test ./internal/handlers/...       # ✅ PASS
go test ./internal/infrastructure/... # ✅ PASS
go test ./internal/nats/...          # ✅ PASS
```

### Frontend Tests
```bash
cd frontend/apps/web
npm test -- --run                    # 98.3% pass rate
npm test -- --run --coverage         # Coverage generation ready
```

## 🚀 Next Steps

1. **Run Integration Tests**
   ```bash
   cd backend
   go test -tags=integration ./internal/search/...
   go test -tags=integration ./internal/graph/...
   go test -tags=integration ./internal/db/...
   go test -tags=integration ./internal/repository/...
   ```

2. **Review Frontend Linting**
   - Many unsafe fixes skipped
   - Review and manually fix critical issues
   - Run: `npm run lint:fix -- --unsafe` (with caution)

3. **Fix Remaining Frontend Test Failures**
   - 2 tests still failing in `CreateLinkForm.test.tsx`
   - Review and fix timeout/async issues

4. **Generate Final Coverage Reports**
   - Backend: `go test -coverprofile=coverage.out ./internal/...`
   - Frontend: `npm test -- --run --coverage`
