## 📝 NOTES

### Known Issues

1. **Validation Logic**: ParameterManager validation có logic `GoodTrackingBlend < PoorTrackingBlend` - có thể cần review lại logic này
2. **Metrics Calculation**: Một số edge cases có thể return NaN - cần handle better
3. **Test Data**: TestHelpers.CreateTelemetryHistory() có thể cần improve để có realistic timestamps

### Recent Fixes (2026-01-27)

1. **DI Container Fix**: Fixed ITestExecutor registration - changed from concrete class to interface registration
2. **Entity Framework Configuration**: 
   - Added JSON conversion cho all complex types trong NavigationParameterSet
   - Configured proper enum conversions (TestStatus, ViolationType, ViolationSeverity)
   - Added optimized indexes cho performance
   - Configured proper relationships với cascade delete
   - Added MaxLength constraints cho string properties
3. **Project Structure**: Created NavigationTune.Shared project để decouple frontend from backend
4. **Build Issues**: Fixed all compilation errors related to namespace changes và missing references

### Design Decisions

1. **Abstract Class Persistence**: Sử dụng `TestScenarioEntity` với JSON serialization thay vì EF Core TPH
2. **Simplified Controllers**: PurePursuit và VelocityEstimator được simplified với custom DTOs
3. **Adapter Pattern**: Sử dụng adapters để decouple từ RobotApp dependencies
