+## Key Findings Summary
+
+### Finding 1: Asset Scoring Architecture COMPLETE ✓

+- **Status**: Production-ready
+- **Components**: 4-factor model (ML 40%, momentum 30%, value 20%, liquidity 10%)
+- **Tests**: 100% passing
+
+### Finding 2: Feature Extraction EXISTS but NOT INTEGRATED ✗
+- **Two Systems**:
+  - Real-time 26-dimensional (common/src/ml_strategy.rs)
+  - Production 256-dimensional (ml/src/features/extraction.rs)
+- **Current Usage**: ML model inference and training only
+- **Missing**: Integration with asset selection scoring
+
+### Finding 3: Asset Scoring Feature-Blind ✗
+- **Current Input**: Pre-calculated values (external data)
+- **Missing**: Real-time feature extraction per asset
+- **Impact**: Cannot adapt weights by feature regime
+
+### Finding 4: Portfolio Allocation NOT IMPLEMENTED ✗
+- **Location**: services/trading_agent_service/src/allocation.rs
+- **Status**: 6-line stub
+- **Missing**: 5 allocation strategies (Equal-Weight, Risk Parity, Mean-Variance, ML-Optimized, Kelly)

+
+## Critical Gaps for Wave C
+
+| Gap | Current | Needed | Impact |
+|-----|---------|--------|--------|
+| Feature Extraction | select_assets() returns empty | Integrate MLFeatureExtractor | Required for Wave C |
+| Feature-Based Scoring | Pre-calculated inputs | Map 26-dim features to scores | Enables adaptive weighting |
+| Portfolio Allocation | Pure stub | 5 allocation algorithms | Blocks position sizing |
+| Feature Regime | Not utilized | Market regime detection | Prevents adaptive switching |
