Wave 9 Agent 9: Files Requiring Updates (If Needed)
Status: ✅ NO UPDATES NEEDED - All callers already use mut extractor
Caller Analysis
Files That Call extract_current_features()
1. ml/src/features/extraction.rs (Line 98)
Status: ✅ No change needed
Reason: Extractor already declared as mut on line 89
// Line 89
let mut extractor = FeatureExtractor::new();
// Line 98
let features = extractor.extract_current_features()?; // ✓ Works with &mut self
2. ml/src/trainers/dqn.rs (Line 925)
Status: ✅ No change needed
Reason: Extractor already declared as mut on line 915
// Line 915
let mut extractor = FeatureExtractor::new();
// Line 925
let features_225 = extractor.extract_current_features()?; // ✓ Works with &mut self
Potential Future Callers
If new code calls extract_current_features(), it must:
-
Declare the extractor as mutable:
let mut extractor = FeatureExtractor::new(); // Must be mut -
Ensure mutable borrow is available:
let features = extractor.extract_current_features()?; // Requires &mut
Common Pattern
use ml::features::extraction::{extract_ml_features, FeatureExtractor};
// Option 1: Use the public API (recommended)
let features = extract_ml_features(&bars)?;
// Option 2: Custom extraction (advanced)
let mut extractor = FeatureExtractor::new(); // ← Must be mut
for bar in bars.iter() {
extractor.update(bar)?;
let features = extractor.extract_current_features()?; // ← Needs &mut
}

✅ 0 errors related to signature change
Why No Updates Were Needed
The signature change from &self to &mut self is fully backward compatible because:
- All existing callers already declare
let mut extractor - Rust allows mutable references where immutable references were previously used
- The change makes the API more flexible (supports both mutable and stateful operations)
Agent 10 Recommendation
No additional caller updates are needed. Agent 10 can proceed directly to wiring extract_wave_d_features() into the pipeline.
