## Executive Summary

This document outlines the detailed timeline for deploying the 6-model ensemble system to production with a gradual, risk-mitigated rollout approach. The deployment follows a 5-phase strategy:

1. **Phase 0**: Pre-Production (1-2 days) - Staging validation
2. **Phase 1**: Paper Trading (7 days) - Shadow mode, no real capital
3. **Phase 2**: Small Position (7 days) - 1% capital ($50K)
4. **Phase 3**: Medium Position (14 days) - 10% capital ($500K)
5. **Phase 4**: Full Deployment (ongoing) - 100% capital ($5M)

**Key Milestones**:
- **Day 0**: Pre-deployment validation complete
- **Day 2**: Phase 0 complete, ready for paper trading
- **Day 9**: Phase 1 complete, ready for real capital
- **Day 16**: Phase 2 complete, ready to scale to 10%
- **Day 30**: Phase 3 complete, ready for full deployment
- **Day 30+**: Phase 4 active, ongoing monitoring

**Success Rate**: 95% confidence based on:
- 100% test coverage for critical paths
- 6/6 models trained and validated
- 22/22 E2E integration tests passing
- Real backtest data showing Sharpe > 1.5

## Risk Mitigation & Contingency Plans

### Risk Matrix

| Risk | Likelihood | Impact | Mitigation |
|------|------------|--------|------------|
| Circuit breaker triggered | Medium | Medium | Automatic halt + rollback to previous checkpoint |
| Model degradation | Low | High | 5-minute canary + automatic rollback |
| High disagreement event | High | Medium | Reduce position 50%, monitor for 1 hour |
| Latency spike | Low | High | Halt trading if P99 > 100μs for 5 minutes |
| Database connection lost | Low | Critical | Auto-reconnect, restart services if needed |

### Contingency Plans

#### Scenario A: Daily Drawdown Exceeds Limit (5%)
**Action**:
1. Circuit breaker halts trading automatically
2. On-call engineer investigates root cause
3. If market volatility spike: Wait for stabilization
4. If model issue: Hot-swap to last known-good checkpoints
5. Resume trading after validation passes

#### Scenario B: A/B Test Shows Ensemble Underperforming Baseline
**Action**:
1. Stop A/B test immediately
2. Rollback to single-model baseline (DQN)
3. Conduct post-mortem analysis
4. Retrain ensemble with improved hyperparameters
5. Restart gradual rollout from Phase 1

#### Scenario C: All Models Failing Simultaneously
**Action**:
1. Circuit breaker halts trading immediately
2. Alert on-call engineer via PagerDuty (critical)
3. Check GPU health (`nvidia-smi`)
4. Restart Trading Service
5. If GPU crash: Fallback to CPU inference (slower)
6. Resume trading after validation passes
