## Wave D Feature Indices (201-224)

```
CUSUM Statistics:       201-210 (10 features)
ADX & Directional:      211-215 (5 features)
Regime Transitions:     216-220 (5 features)
Adaptive Strategies:    221-224 (4 features)
──────────────────────────────────────────────
Total Wave D Features:  201-224 (24 features)
```

## Test Execution

```bash
# Run validation tests
cargo test -p ml --test wave_d_ml_model_input_test --no-fail-fast -- --nocapture

# Results
12 passed, 0 failed, 1 ignored (0.19s)
```

---

## Backward Compatibility

```
Wave C: 201 features (indices 0-200)
Wave D: 225 features (indices 0-224)
Delta:  +24 features (appended at end)

✅ Retraining required: Input layer only
✅ Hidden layers: Can reuse Wave C weights
✅ No feature index conflicts
```
