#### Dependencies

- Backend APIs ready: GET/POST `/api/mcp-tokens`, DELETE `/api/mcp-tokens/{id}`, GET `/api/mcp-tokens/{id}/audit-logs`
- shadcn/ui components: Dialog, Table, Checkbox
- Day 6 Settings infrastructure complete

#### Risks

- Permission matrix UI complex (many checkboxes) (mitigation: clear visual grouping, templates)
- Token display security (prevent screenshots) (mitigation: warning messages only, no technical prevention)
- Audit log pagination performance (mitigation: server-side pagination, limit to 50 per page)

## Dependencies and Critical Path

### Critical Path Analysis

**Critical Path:** Day 1 → Day 2 → Day 3 → Day 4 → Day 9 (Backend-dependent path)

```
Day 1: Domain Layer (COMPLETE)
  ↓
Day 2: Infrastructure + TenantContext
  ↓
Day 3: Application Layer + APIs
  ↓
Day 4: Migration Prep + Testing
  ↓ (Backend Ready)
Day 5: Frontend Core (can start if APIs mocked)
  ↓
Day 6: Frontend Settings
  ↓
Day 7: Frontend MCP
  ↓ (Frontend Ready)
Day 8: Integration Testing
  ↓
Day 9: Production Migration
  ↓
Day 10: Validation
```

### Parallel Work Opportunities

**Days 5-7 (Frontend) can start in parallel with Days 2-4 (Backend) if:**
- API contracts defined (DONE - API integration guide complete)
- MSW mocks configured for frontend development
- Backend APIs deployed to staging environment when ready

**Optimization:**
- Frontend team can start Day 5 tasks while backend completes Day 3
- This compresses timeline by 1-2 days if backend APIs are delayed

### Dependencies Matrix

| Task | Depends On | Blocks |
|------|-----------|--------|
| Day 1: Domain | - | Day 2 |
| Day 2: Infrastructure | Day 1 | Day 3 |
| Day 3: Application + APIs | Day 2 | Day 4, Day 5 (for real API testing) |
| Day 4: Migration Prep | Day 3 | Day 9 |
| Day 5: Frontend Core | API contracts (done), ideally Day 3 for real APIs | Day 6 |
| Day 6: Frontend Settings | Day 5 | Day 7 |
| Day 7: Frontend MCP | Day 6 | Day 8 |
| Day 8: Integration Testing | Days 4 + 7 | Day 9 |
| Day 9: Migration | Days 4 + 8 | Day 10 |
| Day 10: Validation | Day 9 | - |

## Risk Management

### High-Risk Items

| Risk | Probability | Impact | Mitigation |
|------|-------------|--------|------------|
| **Data loss during migration** | Low | Critical | Full backup, tested rollback, validation scripts |
| **Extended downtime** | Medium | High | Pre-test migration, have rollback ready, schedule off-peak |
| **Performance degradation** | Medium | High | Performance testing on Day 4, proper indexes |
| **Critical bugs found on Day 8** | Medium | High | Allow extra time on Day 9 for fixes |
| **SSO integration issues** | Low | Medium | Test with real IdPs, clear error messages |

### Risk Mitigation Strategies

1. **Technical Risks:**
   - Comprehensive testing (unit, integration, E2E, security)
   - Code reviews (all PRs reviewed by at least one other developer)
   - Performance testing before production (Day 4)
   - Staging environment mirrors production

2. **Schedule Risks:**
   - Buffer time built into Days 8-9 (can absorb 1-day delay)
   - Frontend can start earlier if APIs mocked
   - Rollback plan tested and ready

3. **Quality Risks:**
   - TDD approach (tests written alongside code)
   - Integration tests verify tenant isolation
   - Security tests before production
   - Code coverage target: >80%
