## Recommendations
### High Priority (Wave 114)
1. **Validate all 23 tests pass** when build completes
2. **Measure actual coverage** with tarpaulin
3. **Document any failures** and fix immediately
### Medium Priority (Wave 115)
1. **Add equity curve tests** (2 tests, 50 lines coverage)
- Test with various trade patterns
- Validate resampling logic
2. **Add rolling metrics tests** (2 tests, 60 lines coverage)
- Test window calculations
- Validate time series aggregation
### Low Priority (Wave 116+)
1. **Add drawdown period tests** (2 tests, 44 lines coverage)
- Test period identification
- Validate duration calculations
2. **Integration tests** for complete workflow

## Expected Coverage After Full Implementation
| Phase | Tests | Lines | Coverage % |
|-------|-------|-------|------------|
| **Agent 8** (Current) | 23 | 455 | 75% |
| + Equity curve tests | 25 | 505 | 83% |
| + Rolling metrics tests | 27 | 565 | 93% |
