## ✅ Test Coverage Verification

### Required Tests (10)

- [x] Test 1: Stable returns (low volatility → higher multiplier)
- [x] Test 2: Volatile returns (high volatility → lower multiplier)
- [x] Test 3: Insufficient history (<20 samples → raw pnl_change)
- [x] Test 4: Positive PnL + positive Sharpe → amplified reward
- [x] Test 5: Positive PnL + negative Sharpe → penalized reward
- [x] Test 6: Zero volatility → raw pnl_change
- [x] Test 7: Rolling window (last 20 samples used)
- [x] Test 8: Outlier handling (no NaN/Inf)
- [x] Test 9: Logging (every 100 steps)
- [x] Test 10: Baseline comparison (risk-adjusted > raw)

### Bonus Tests (4)

- [x] Test 11: Negative PnL with positive Sharpe
- [x] Test 12: Exactly 20 samples boundary
- [x] Test 13: Large history stress test (500 samples)
- [x] Test 14: Rapid history turnover stress test

**Total**: 14/14 tests ✅
