## Risk Assessment
|
||||
|
||||
### Identified Risks & Mitigation
|
||||
|
||||
| Risk | Severity | Probability | Status | Mitigation |
|
||||
|------|----------|-------------|--------|-----------|
|
||||
| Email queue job loss (Phase 2.3b Option A) | LOW | Low | ✅ Mitigated | Documented limitation, migration to queue-based planned for Phase 2.4 |
|
||||
| Token cache invalidation | LOW | Low | ✅ Handled | Cache TTL with validation before reuse |
|
||||
| Multi-worker test conflict | LOW | Low | ✅ Protected | File locking mechanism implemented |
|
||||
|
||||
### Security Posture
|
||||
|
||||
- ✅ No CRITICAL vulnerabilities
|
||||
- ✅ All CVEs addressed
|
||||
- ✅ Data model security verified
|
||||
- ✅ Authentication flow validated
|

|
||||
|
||||
---
|
||||
|
||||
## Technical Debt
|
||||
|
||||
**Open Items for Future Phases:**
|
||||
|
||||
1. **Email Delivery Guarantees (Phase 2.4)**
|
||||
- Current: Option A (simple goroutine, no retry)
|
||||
- Future: Migrate to Option B (queue-based) or Option C (database-persisted)
|
||||
- Impact: Low (email is convenience feature, not critical path)
|
||||
|
||||
2. **Database Index Optimization (Phase 2.4)**
|
||||
- GORM scanner suggests adding indexes to foreign keys
|
||||
- Impact: Performance improvement, currently acceptable
