## 🚦 Risk Assessment

### Low Risk Items (Quick Fixes)
- ✅ Adding Default traits (5 minutes)
- ✅ Adding missing imports (5 minutes)
- ✅ Adding dependencies (2 minutes)
- ✅ Type annotations (10 minutes)

### Medium Risk Items (Moderate Effort)
- ⚠️ ServiceManager API updates (30 minutes)
- ⚠️ Error conversion implementations (30 minutes)
- ⚠️ Test infrastructure restoration (45 minutes)

### Higher Risk Items (Complex Changes)
- ⚠️ Type mismatch resolution (60 minutes) - May reveal API inconsistencies
- ⚠️ Private access fixes (30 minutes) - May require architectural decisions

### Mitigation Strategy
- Commit after each agent completes
- Test incrementally during fixes
- Document any unexpected issues
- Keep Wave 33 state as rollback point
