ARCHITECTURAL FIX: Resolves critical feature dimension mismatch
- Training: 256 features → 225 features
- Inference: 30 features → 225 features
- Models: 16-32 features → 225 features (ready for retraining)
CHANGES:
Wave 1-2: Create common/src/features/ module structure
- Created features/mod.rs (module root)
- Created features/types.rs (FeatureVector225 = [f64; 225])
- Created features/technical_indicators.rs (510 lines: RSI, EMA, MACD, Bollinger, ATR, ADX)
- Created features/microstructure.rs (skeleton)
- Created features/statistical.rs (skeleton)
Wave 3: Implement dual API (streaming + batch)
- Streaming API: RSI, EMA, MACD, BollingerBands, ATR, ADX (stateful calculators)
- Batch API: rsi_batch, ema_batch, macd_batch, bollinger_batch, atr_batch, adx_batch
- Zero-cost abstraction: No runtime performance degradation
Wave 4: Integration
- Updated common/src/lib.rs: Export features module + 12 public types/functions
- Updated ml/src/features/extraction.rs: [f64; 256] → [f64; 225], use common::features
- Updated ml/src/features/unified.rs: FeatureVector → [f64; 225]
- Updated common/src/ml_strategy.rs: Added 7 indicator calculators, extended to 225 features
- Fixed 24 test assertions across 7 files (30/256 → 225)
