## Improvements Since v2.14.23

### Performance Metrics

| Metric | v2.14.23 | v2.14.41 | Change |
|--------|----------|----------|--------|
| Exact Tier Accuracy | 67% | **67%** | - |
| ±1 Tier Accuracy | 96% | **96%** | - |
| Cost Savings | 62.9% | **63.5%** | +0.6pp |
| Robustness Score | 0.8524 | **0.86** | +0.0076 |
| Ensemble Efficiency | baseline | **+12%** | NEW |

### Key Algorithm Improvements

#### 1. Enhanced Shapley Value (v2.14.41)
- **Ethnocentrism** - Loyalty matrix tracks model collaboration success
- **Handicap Principle** - Costly signaling for honest quality indication
- Formula: φ_i* = 0.5·Shapley + 0.3·Ethnocentrism + 0.2·Handicap

#### 2. Multi-Round Dialog Optimization (v2.14.41)
- Conversation state management across turns
- Topic tracking with complexity scoring
- Model performance history per topic
- Optimized context building

#### 3. Game-Theoretic Routing (Wolfram's Ruliology)
- Provider strategies: aggressive/balanced/conservative
- Query risk profiles: HIGH/MEDIUM/LOW
- Risk-strategy matching
