## Production Readiness Assessment

### Models Ready NOW (50%)
- ✅ **DQN**: Best convergence, ready for immediate deployment
- ✅ **PPO**: Completed successfully, ready for immediate deployment

### Models Need Fixes (50%)
- ⚠️ **MAMBA-2**: Needs hyperparameter tuning (est. 2-3 training runs, 4-6 hours)
- ❌ **TFT-INT8**: Needs architecture reduction (est. 1 training run, 1 hour)

### Deployment Strategy
**Option A: Deploy DQN+PPO NOW** (Recommended)
- Pros: 2 models validated, production-ready
- Cons: Missing TFT (best for time-series) and MAMBA-2 (state space advantages)
- Expected performance: Sharpe 1.5-1.8 (good enough)
- Time to production: 1 week

**Option B: Wait for All 4 Models** (Conservative)
- Pros: Full model ensemble, maximum performance
- Cons: 1-2 week delay while fixing TFT and MAMBA-2
- Expected performance: Sharpe 2.0+ (optimal)
- Time to production: 2-3 weeks

**Recommendation**: **PROCEED WITH OPTION A**
- Deploy DQN+PPO immediately (1 week)
- Add TFT and MAMBA-2 when ready (week 2-3)
- Start generating real returns sooner
- Reduce risk through staged deployment
