# NFOGuard Development Summary

## Current Status: v1.3.2 - Path Mapping Fix & Database Migration

### Latest Updates (v1.3.2)
- **🐛 CRITICAL**: Fixed path mapping bug converting `movies6` to `movies/6`
- **🔧 DATABASE**: Added automatic migration for `has_video_file` columns
- **🎯 PATH CONFIG**: Removed all hardcoded paths - fully configurable via environment
- **📝 VALIDATION**: Enhanced path validation in webhook processing
- **🔍 DEBUG**: Added debug logging to path mapper for troubleshooting

### Path Mapping Logic (Fixed)
```
Radarr webhook: /mnt/unionfs/Media/Movies/movies6/Annabelle...
↓ Match RADARR_ROOT_FOLDERS[1]: /mnt/unionfs/Media/Movies/movies6
↓ Map to MOVIE_PATHS[1]: /media/Movies/movies6  
✅ Result: /media/Movies/movies6/Annabelle...
```

### Environment Configuration Required
- `MOVIE_PATHS=/media/Movies/movies,/media/Movies/movies6`
- `TV_PATHS=/media/TV/tv,/media/TV/tv6`
- `RADARR_ROOT_FOLDERS=/mnt/unionfs/Media/Movies/movies,/mnt/unionfs/Media/Movies/movies6`
- `SONARR_ROOT_FOLDERS=/mnt/unionfs/Media/TV/tv,/mnt/unionfs/Media/TV/tv6`

### Previous Updates (v1.3.1)
- **🐛 FIXED**: 'container_path' undefined variable error in Radarr webhook handler
- **🔧 ENHANCED**: Webhook now properly handles both 'folderPath' and 'path' fields
- **✅ VALIDATION**: Added mandatory path validation before processing
- **🎯 BATCH**: Enhanced batch processing with IMDb ID validation to prevent cross-processing

### Zero Hardcoded Paths
- ✅ No default fallback paths in configuration
- ✅ Application fails with clear error if paths not configured
- ✅ Works with any folder structure
- ✅ Completely portable between environments

### Database Migration Support
- ✅ Automatic schema updates for existing databases
- ✅ Graceful handling of missing columns
- ✅ Backward compatibility maintained

### Webhook Processing Flow
1. **Reception**: Webhook received and parsed
2. **Path Resolution**: External path mapped to container path using environment mappings
3. **Validation**: Verify mapped path exists and IMDb ID matches
4. **Batching**: Add to processing queue with anti-storm protection
5. **Processing**: Date resolution, NFO creation, file timestamp updates
6. **Database**: Record processing history and results

### Technical Architecture
- **Path Mapper**: Environment-configurable path translation
- **NFO Manager**: Creates metadata files with proper date attribution
- **Database Manager**: SQLite with automatic migration support
- **Webhook Batcher**: Intelligent batching with validation
- **Client Managers**: API access for external services

### Debug Features
- **Path Mapping Debug**: Detailed logging of path translation process
- **Health Endpoint**: Database and external service status
- **Statistics API**: Comprehensive media library statistics
- **Debug Endpoints**: Movie import analysis, TMDB lookup testing

## Configuration Requirements

### Critical Environment Variables
```bash
# Required - Application will fail without these
MOVIE_PATHS=/your/container/movie/paths
TV_PATHS=/your/container/tv/paths
RADARR_ROOT_FOLDERS=/host/radarr/paths
SONARR_ROOT_FOLDERS=/host/sonarr/paths

# Database and logging
DB_PATH=/app/data/media_dates.db
LOG_DIR=/app/data/logs
```

### Known Issues
- Path mapping must exactly match your container and host configurations
- Database requires migration for existing installations
- Debug logging may be verbose during path mapping troubleshooting
