## Known Issues (Non-Blocking)

### Issue 1: Pre-existing Test Compilation Errors
**Files**:
- `services/backtesting_service/tests/ml_strategy_backtest_test.rs:395`
- `services/backtesting_service/tests/dbn_multi_day_tests.rs:176`

**Status**: Pre-existing (not Wave D related)
**Impact**: Test code only, production code unaffected
**Action**: Defer to Wave E cleanup phase

### Issue 2: Regime Tables Empty
**Status**: Expected (no live data streamed yet)
**Impact**: None - tables ready for production data
**Action**: Will populate during live trading

### Issue 3: No Dedicated Adaptive Strategy E2E Tests
**Status**: Implementation exists, E2E tests missing
**Impact**: Non-blocking - unit tests pass
**Action**: Add in Wave E
