## Risk Mitigation

### Critical Path Risk: Sync Engine (24h)
- **Risk:** Scope creep, hidden complexity in conflict resolution
- **Mitigation:** 4h checkpoints, real-time blocker escalation, parallel work independence
- **Fallback:** If sync engine slips, parallel work (3.1-3.3) completes independently

### Dependency Risk: Auth Blocking Frontend
- **Risk:** Auth system delays prevent frontend work
- **Mitigation:** Parallel work on handlers/API in parallel, Frontend work deferred to T+4-8h
- **Fallback:** Use mock auth if real auth slips

### Integration Risk: Phase 4 Depends on Phase 3
- **Risk:** Phase 3 incomplete at T+24h
- **Mitigation:** Aggressive checkpoint schedule, real-time monitoring
- **Fallback:** Phase 4 begins with Phase 3 in-progress if needed (non-blocking)
