1. Configuration Validation

1.1 wave_d() Method Implementation

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

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)

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

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)

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 ✅
