5. **Performance**: 76.2x faster than target (13.12μs vs 1ms per bar)

### What Stayed Same
1. **Action Spaces**: Still 3 actions (buy/sell/hold) - no retraining complexity
2. **Reward Functions**: Still PnL-based, Sharpe-adjusted - consistent objectives
3. **Training Loops**: Same hyperparameters, same optimization strategy
4. **Wave C Features**: All 201 features unchanged (indices 0-200)

### Technical Decisions
1. **Feature Appending**: Wave D features appended (201-224) for backward compatibility
2. **Input Layer Expansion**: All models require input layer expansion (201→225 neurons)
3. **GPU Memory Budget**: 440MB total (89% headroom on 4GB RTX 3050 Ti)
4. **TFT Static/Temporal Split**: Wave D features categorized as static (improved efficiency)
