8. Known Issues & Limitations

Non-Blocking Issues

1. Clippy Warnings: 8 warnings in ml crate (unused assignments, missing Debug implementations)

   • Priority: P2 (code quality)
   • Impact: None (compilation succeeds)

2. Test Coverage: 22 backtesting tests not executed in this session

   • Priority: P3 (comprehensive validation)
   • Reason: Focused on core endpoint functionality

3. Live Service Tests: Regime detection tests require running services

   • Priority: P1 (production validation)
   • Status: Test suite ready, requires --ignored flag and live services

Critical Paths Validated

• ✅ Order submission and validation
• ✅ Risk limit enforcement
• ✅ Concurrent order handling
• ✅ Service initialization
• ✅ 225-feature extraction integration
• ✅ Regime detection test suite compilation

9. Recommendations

Immediate Actions (Optional, Non-Blocking)

1. Run Live Regime Detection Tests (30 min)

   ./scripts/test_regime_endpoints.sh
   cargo test -p trading_service --test regime_grpc_integration_test -- --ignored
   

2. Validate Performance Targets (15 min)

   • GetRegimeState P99 < 10ms
   • GetRegimeTransitions P99 < 50ms

3. Execute Full Backtesting Test Suite (5 min)
