## Dependencies & Execution Order

### Sequential Dependencies
- **Phase 1** → **Phase 2**: Database must exist before resolver can cache
- **Phase 2** → **Phase 3**: Resolver must exist before snapshot enrichment
- **Phase 2** → **Phase 4**: Definitions needed for normalizer
- **Phase 4** → **Phase 5**: Normalized data structure needed for UI
- **Phase 5** → **Phase 7**: UI must exist before feature tests

### Parallel Opportunities
- **Phase 2** (T003-T007): Resolver methods can be implemented in parallel
- **Phase 4** (T011-T014): Normalizer sub-methods can be implemented in parallel
- **Phase 5** (T015-T022): UI components can be developed in parallel after T015
- **Phase 7** (T026-T031): Unit tests can be written in parallel
- **Phase 7** (T032-T037): Feature tests can be written in parallel

### Example Parallel Execution
**Phase 2**:
- Developer A: T003, T004 (resolve methods)
- Developer B: T005, T006 (resolveOne + fallback)
- Both converge for T007 (warmCache)

**Phase 5**:
- Developer A: T015-T017 (tabs + accordion setup)
- Developer B: T018-T020 (rendering logic)
- Both converge for T021-T022 (search functionality)

| Phase 4: Normalizer | 4 | ~2-3 hours | Phase 2 |
| Phase 5: UI Settings | 8 | ~3-4 hours | Phase 4 |
| Phase 6: UI Tabs | 3 | ~1 hour | Phase 5 |
| Phase 7: Testing | 17 | ~3-4 hours | Phase 2-6 |
| **Total** | **42** | **11-15 hours** | |

## Constitution Compliance Evidence

| Principle | Evidence | Tasks |
|-----------|----------|-------|
| Safety-First | Read-only UI, no edit capabilities | All UI tasks |
| Immutable Versioning | Snapshot enrichment non-blocking, metadata only | T008-T010 |
| Defensive Restore | Not applicable (read-only feature) | N/A |
| Auditability | Raw JSON still accessible via tab | T023-T025 |
| Tenant-Aware | Resolver respects tenant scoping (via GraphClient) | T003-T007 |
| Graph Abstraction | Uses existing GraphClientInterface | T003-T007 |
| Spec-Driven | Full spec + plan + tasks before implementation | This document |

---

## Risk Mitigation Tasks

- **Risk**: Graph API rate limiting
  - **Mitigation**: T007 (warmCache is non-blocking), aggressive DB caching
- **Risk**: Definition schema changes by Microsoft
  - **Mitigation**: T001 (raw JSONB storage), T006 (fallback logic)
- **Risk**: Large policies slow UI
  - **Mitigation**: T017-T018 (accordion lazy-loading), performance tests in T042

---

## Notes for Implementation

1. **Feature 002 Dependency**: Feature 003 uses tabs from Feature 002 JSON viewer implementation. Ensure Feature 002 code is stable before starting Phase 5.

2. **Database Migration**: Run migration early (T001) to avoid blocking later phases.

3. **Graph API Endpoints**: Verify access to `/deviceManagement/configurationSettings` endpoint in test environment before implementing T004.

4. **Testing Strategy**: Write unit tests (Phase 7, T026-T031) in parallel with implementation to enable TDD workflow.

5. **UI Polish**: Leave time for manual QA (T042) to catch UX issues not covered by automated tests.

6. **Performance Profiling**: Use Laravel Telescope or Debugbar during T042 to measure actual performance vs NFR targets.
