## Architecture Overview

### Gap 5.3: Frontend Integration Tests

```
Problem: 8 skipped integration tests
├─ Missing MSW handlers (reports, search, export)
├─ Store state contamination (no cleanup)
├─ Incomplete test fixtures
└─ Async timing issues

Solution Architecture:
├─ MSW Handlers → New endpoints (3)
├─ Test Data → Extended mockData
├─ Global Cleanup → afterEach hook + store reset
├─ Test Helpers → Reusable async utilities
└─ Re-enable → Replace 8 it.skip with it()

Success Criteria: 8/8 tests passing, no flakes (5x run), 85%+ coverage
```

### Gap 5.4: Temporal Snapshot Workflow

```
Problem: 1 skipped temporal workflow test
├─ No snapshot activities defined
├─ No snapshot workflow defined
├─ No Temporal test environment
└─ No service integration

Solution Architecture:
├─ Activities → 3 activities (Query, Create, Upload)
├─ Workflow → Chain activities with retries
├─ Test Setup → Temporal test server + worker
└─ Service Integration → Register in service.go

Success Criteria: 1/1 test passing, MinIO upload verified, metadata updated
```

### Gap 5.5: E2E Accessibility Tests

```
Problem: 6 skipped accessibility tests
├─ No table test data (needs 7+ rows)
├─ API handler returns insufficient data
├─ Test fixture doesn't wait for rows
└─ Tests skip due to row count check

Solution Architecture:
├─ Test Data → 10 tableTestItems
├─ API Handler → Updated pagination
├─ Fixture Setup → Wait for 8+ rows
└─ Re-enable → Remove 6 test.skip calls

Success Criteria: 6/6 tests passing, keyboard navigation works, WCAG 2.1 AA compliant
```

## Implementation Schedule

### Execution Model: 3 Parallel Agents + 1 Synchronization Point

```
Phase 1: Parallel (10-15 min)
  Agent 1: MSW handlers + test data (Gap 5.3)
  Agent 2: Activities.go + Workflows.go (Gap 5.4)
  Agent 3: Table test data + API handlers (Gap 5.5)
  ↓ [Sync checkpoint]

Phase 2: Parallel (10-15 min)
  Agent 1: Global cleanup + test helpers (Gap 5.3)
  Agent 2: Test setup + service integration (Gap 5.4)
  Agent 3: Playwright fixture + re-enable (Gap 5.5)
  ↓ [Sync checkpoint]

Phase 3: Parallel (5-10 min)
  Agent 1: Re-enable 8 tests (Gap 5.3)
  Agent 2: Verify workflow registration (Gap 5.4)
  Agent 3: Add WCAG validation (Gap 5.5)
  ↓ [Sync checkpoint]

Phase 4: Sequential Testing (10 min)
  npm test -- app-integration.test.tsx        # Gap 5.3 → 8 passing
  make test-backend TEST_TEMPORAL=1           # Gap 5.4 → 1 passing
  npx playwright test table-accessibility...  # Gap 5.5 → 6 passing

Final: 15/15 tests passing ✓
```

| Store contamination | Comprehensive afterEach cleanup | Agent 1 |
| Async race conditions | Explicit waitFor with timeouts | All agents |
| Temporal env missing | Use test server package | Agent 2 |
| Table data insufficient | Hardcode 10 items (7+ required) | Agent 3 |
