## 1. Configuration Validation

### 1.1 wave_d() Method Implementation

**File**: `/home/jgrusewski/Work/foxhunt/ml/src/features/config.rs` (Lines 345-362)

```rust
/// Wave D configuration: 225 features (regime detection + adaptive strategies)
///
/// Feature breakdown:
/// - Wave C: 201 features (indices 0-200)
/// - Wave D additions: 24 features (indices 201-224)
///   - CUSUM Statistics: 10 features (indices 201-210)
///   - ADX & Directional Indicators: 5 features (indices 211-215)
///   - Regime Transition Probabilities: 5 features (indices 216-220)
///   - Adaptive Strategy Metrics: 4 features (indices 221-224)
/// Total: 225 features (indices 0-224)
pub fn wave_d() -> Self {
    Self {
        phase: FeaturePhase::WaveD,
        enable_ohlcv: true,
        enable_technical_indicators: true,
        enable_microstructure: true,
        enable_alternative_bars: true,
        enable_barrier_optimization: true,
        enable_fractional_diff: true,
        enable_regime_detection: true,
        enable_wave_d_regime: true,  // ✅ CRITICAL: Wave D features enabled
    }
}
```

**Verification**: ✅ All required flags are set to `true`

---

### 1.2 Feature Count Calculation

**Method**: `FeatureConfig::feature_count()` (Lines 366-414)

```rust
pub fn feature_count(&self) -> usize {
    let mut count = 0;

    if self.enable_ohlcv {
        count += 5; // OHLCV features
    }

    if self.enable_technical_indicators {
        count += 21; // Technical indicators
    }

    if self.enable_microstructure {
        count += 3; // Microstructure features
    }

    if self.enable_alternative_bars {
        count += 10; // Alternative bars
    }

    if self.enable_fractional_diff {
        count += 162; // Wave C: 201 - 39 = 162
    }

    if self.enable_wave_d_regime {
        count += 24; // Wave D: CUSUM (10) + ADX (5) + Transitions (5) + Adaptive (4)
    }

    count
}
```

**Breakdown**:
- Base (OHLCV + Technical + Microstructure + Alternative): 5 + 21 + 3 + 10 = **39 features**
- Wave C (fractional_diff): **162 features**
- Wave D (wave_d_regime): **24 features**
- **Total**: 39 + 162 + 24 = **225 features** ✅

---

### 1.3 Live Test Execution

**Command**: `cargo run -p ml --example check_feature_count`

**Output**:
```
Wave A: feature_count: 26
Wave B: feature_count: 36
Wave C: feature_count: 201
Wave D: feature_count: 225
Wave D regime enabled: true

✅ Wave D active (225 features)
```

**Result**: ✅ **VERIFIED - Returns 225 features**

---

## 2. Wave D Features Validation

### 2.1 Feature Definitions

**Function**: `wave_d_features()` (Lines 90-172)

Defines all **24 Wave D features** with proper indexing:

| Feature Group | Index Range | Count | Features |
|---|---|---|---|
| CUSUM Statistics | 201-210 | 10 | cusum_s_plus_normalized, cusum_s_minus_normalized, cusum_break_indicator, cusum_direction, cusum_time_since_break, cusum_frequency, cusum_positive_count, cusum_negative_count, cusum_intensity, cusum_drift_ratio |
| ADX & Directional Indicators | 211-215 | 5 | adx, plus_di, minus_di, dx, trend_classification |
| Regime Transition Probabilities | 216-220 | 5 | regime_stability, most_likely_next_regime, regime_entropy, regime_expected_duration, regime_change_probability |
| Adaptive Strategy Metrics | 221-224 | 4 | position_multiplier, stop_loss_multiplier, regime_conditioned_sharpe, risk_budget_utilization |
| **Total** | **201-224** | **24** | **All features defined** ✅ |

**Feature Categories**:
- `FeatureCategory::RegimeDetection`: 20 features (indices 201-220)
- `FeatureCategory::AdaptiveStrategy`: 4 features (indices 221-224)

---

### 2.2 Feature Indices Mapping

**Method**: `FeatureConfig::feature_indices()` (Lines 416-466)

```rust
if self.enable_wave_d_regime {
    indices.wave_d_regime = Some((current_idx, current_idx + 24));
    // current_idx is 201 for Wave D (39 base + 162 Wave C = 201)
}
```

**Result**: Wave D features correctly map to indices **201-224** ✅
