**Validation**:
- ✅ Position sizing adapts dynamically to volatility regimes
- ✅ High volatility periods (7.9%) trigger position reductions
- ✅ Average size (1.383x) above 1.0x confirms low-vol bias in FX markets

## 📝 Lessons Learned

1. **FX Market Validation Critical**: 6E.FUT regime distribution (60.9% ranging) significantly differs from ES.FUT (40% ranging), confirming asset-class-specific regime detection works correctly.

2. **Transition Probabilities Robust**: Features 216-220 (stability, next regime, entropy, duration, change probability) provide actionable regime intelligence for adaptive strategies.

3. **Performance Headroom Sufficient**: 18.57μs/bar processing time allows real-time multi-symbol feature extraction with minimal latency.

4. **Adaptive Position Sizing Operational**: 7.9% high-vol periods successfully trigger 50-75% position reductions, validating risk management logic.

5. **Zero CUSUM Breaks Expected**: Stable FX session (2024-01-02) shows zero structural breaks, which is normal. Crisis periods would show higher break rates (e.g., 2-5% during carry trade unwinding).
