### Finding 1: Asset Scoring Architecture COMPLETE ✓
|
||
- **Location**: services/trading_agent_service/src/assets.rs
|
||
- **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

## 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 |
