## 3. Code Diff Visualization
|

|
||
### 3.1 Method Signature Change
|
||
|
||
```rust
|
||
// BEFORE (Line 166):
|
||
pub fn extract_current_features(&self) -> Result<FeatureVector> {
|
||
────────
|
||
IMMUTABLE
|
||
❌ Cannot call &mut self methods
|
||
|
||
// AFTER (Line 166):
|
||
pub fn extract_current_features(&mut self) -> Result<FeatureVector> {
|
||
────────────
|
||
MUTABLE
|
||
✅ Can call extract_wave_d_features(&mut self)
|
||
```
|
||
|
||
### 3.2 Feature Extraction Call Chain
|
||
|
||
```rust
|
||
// BEFORE (Lines 195-198):
|
||
// 7. Statistical features (175-224): 50 features ❌ WRONG COUNT
|
||
self.extract_statistical_features(&mut features[idx..idx + 50])?;
|

──────
|

Overwrites 201-224!
|
||
|
||
// Validate no NaN/Inf
|
||
self.validate_features(&features)?;
|
||
Ok(features)
|
||
|
||
|
||
// AFTER (Lines 195-201):
|

// 7. Statistical features (175-200): 26 features ✅ CORRECT COUNT
|
||
self.extract_statistical_features(&mut features[idx..idx + 26])?;
|
||
idx += 26; ──────
|
||
FIXED!
|
||
|

// 8. Wave D regime detection features (201-224): 24 features ✅ NEW
|

self.extract_wave_d_features(&mut features[idx..idx + 24])?;
|

─────────────────────────────────────────────────────────

✅ NOW CALLED! Fills features 201-224 with regime data
