Instead implemented a wrapper repository following adapter pattern. **Key Technical Decisions**: 1. Domain vs Application Layer: Moved to domain layer (repository concerns) 2. Macro vs Manual: Used macro to generate 15 state-specific methods 3. Wrapper vs Trait: Wrapper pattern simpler and more maintainable 4.
