## Critical Bug Fixes & Resolutions
### CSV Export Test Failure
- **Issue**: Test expected 'userId' field but service generated flattened format
- **Root Cause**: `convertToCSV` method didn't handle user activity report format
- **Solution**: Added format detection for `data.users` array with proper header mapping
- **Result**: All 31 tests passing with correct CSV generation
### TypeScript Compilation Issues
- **Challenge**: Multiple import path and type definition errors
- **Approach**: Systematic resolution of module imports and type declarations
- **Status**: Core services compile successfully, some existing files have unrelated errors
