## Smart Metadata Application Logic
### Direct Replacement Mode (Default)
- Takes metadata from preferred provider exactly as provided

* Covers: Only replace if higher resolution
* Authors: Always update for consistency
* Tags/Series: Always add for discoverability

- Updated fetch_and_apply_metadata() for admin-only control
- Integrated CWA_DB settings checking for both modes
### Ingest Processor (scripts/ingest_processor.py)
- Removed user-based metadata checking
- Streamlined to use admin settings only
- Improved processing pipeline integration
### Form Processing (cps/cwa_functions.py)

## Integration & Compatibility
- Maintains backward compatibility with existing email settings
- Integrates seamlessly with auto-convert and ingest systems
- Respects existing access controls and user permissions
- No breaking changes to existing functionality
## Testing Notes
- Database schema updates will apply automatically on app startup
- Settings form processing handles new boolean field automatically
- Metadata fetching now controlled entirely by admin settings
- User interface cleaned of deprecated metadata controls
This implementation provides a complete automated book delivery and metadata enhancement system while maintaining the principle of admin-controlled automation and user-friendly operation.
