+
+## 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
