Critical Path to Backend MVP
Backend MVP = Phase 0 + Phase 1 + Phase 2
Immediate Blocker: Redis Memorystore
Status: ❌ NOT DEPLOYED
Impact: Blocks ALL backend development (views.py requires Redis for atomic seat counting)
Fix Time: 30 minutes
Priority: P0 - CRITICAL
Fix Command: ```bash cd opentofu/environments/dev tofu apply -target=module.redis gcloud redis instances list --region=us-central1 ```
Timeline to Backend MVP
Day 1 (Today - 4-5 hours):
- Deploy Redis Memorystore (30 min) ⬅️ BLOCKER REMOVAL
- Create Services layer (2-3 hours)
- Start test suite (1-2 hours)
Day 2 (Tomorrow - 5-6 hours): 4. Complete tests (3-4 hours) 5. Create Dockerfile (1 hour) 6. Create Kubernetes manifests (2 hours)
Day 3 (Day After - 4 hours): 7. Deploy to GKE (2 hours) 8. Integration testing (2 hours) 9. Backend MVP Complete 🎯
Total Timeline: 2-3 days (IF Redis deployed TODAY)

Critical Path Analysis
What Blocks What?
Backend MVP Critical Path:
Redis Deployment (30 min)
↓
Services Layer (2-3h)
↓
Test Suite (4-5h)
↓
Docker + K8s (3h)
↓
GKE Deployment (2h)
↓
Backend MVP Complete
Phase 7 Deferred Work: NOT on critical path
- Does NOT block backend development
- Can be done in parallel by technical writer
- Primarily documentation completeness tasks
Resource Allocation Recommendation
Track 1: Backend MVP (Critical Path)
- Resource: 1 Backend Developer (full-time)
- Duration: 2-3 days
- Focus: Services, tests, deployment
- Priority: P0 - CRITICAL
Track 2: Phase 7 Completion (Parallel)
- Resource: 1 Technical Writer (part-time)
- Duration: 6-7 days
- Focus: Remaining diagrams and documentation
- Priority: P1 - Important but not blocking
These tracks can run IN PARALLEL ✅

Success Metrics
Backend MVP Success Criteria (2-3 days):
- ✅ Redis Memorystore deployed and operational
- ✅ Services layer complete with Cloud KMS signing
- ✅ 80%+ test coverage
- ✅ Docker container builds successfully
- ✅ Kubernetes deployment successful
- ✅ All license endpoints working (acquire, heartbeat, release)
- ✅ Integration tests pass
Phase 7 Success Criteria (30 hours deferred):
- ✅ All 35 tasks complete (100%)
- ✅ All C3 diagrams created (8 total)

Risk Assessment
| Risk | Impact | Probability | Mitigation |
|---|---|---|---|
| Redis not deployed today | HIGH | MEDIUM | Deploy immediately (30 min) |
| Backend tests take longer | MEDIUM | MEDIUM | Allocate extra day if needed |
| Phase 7 delays MVP | LOW | ZERO | NOT on critical path |
| Missing diagrams cause confusion | LOW | LOW | Core diagrams complete (7A-7C) |
| FastAPI refs remain in docs | LOW | ZERO | All critical conversions done |
Conclusion
Phase 7 Progress: 60% complete (20/35 tasks) with all critical conversions finished.
Backend MVP: 68% complete, 2-3 days away, BLOCKED ONLY by Redis deployment (30 min fix).
Deferred Work: 15 tasks (30 hours) NOT blocking backend MVP, can be completed in parallel by technical writer.
Immediate Action Required:
- Deploy Redis Memorystore (30 min) - Unblocks entire backend critical path
- Commit Phase 7 progress (10 min) - Preserve work completed this session
- Start Backend MVP track (2-3 days) - Services, tests, deployment
Timeline:
- Backend MVP: 2-3 days (if Redis deployed TODAY)
- Phase 7 Complete: 6-7 days (parallel track, technical writer)
- Overall: Both tracks complete in ~1 week
