NFOGuard Project Summary

📋 Current Status: v0.6.0 (In Development)

🎯 Project Goal

Preserve movie and TV import dates in Emby/Jellyfin/Plex by preventing upgraded files from appearing as "recently added". NFOGuard listens to Radarr/Sonarr webhooks and manages .nfo files and file timestamps to maintain chronological consistency.

🚀 Major Achievements

Database-Only Architecture (v0.5.0+)

• Performance: 10x faster than API-based approach
• Reliability: Direct PostgreSQL database queries eliminate API limitations
• Scalability: Handles 1500+ movies without pagination issues

🎯 Configurable Release Date Priority System (v0.6.0)

• Three-Tier Priority System: Digital → Physical → Theatrical (fully configurable)
• Smart Fallbacks: "The Craft (1996)" gets 1996 theatrical, "Top Gun Maverick (2022)" gets digital
• Per-Movie Intelligence: Automatically adapts to movie era and available release data
• Source Tracking: NFO files annotated with chosen date source (tmdb:theatrical, tmdb:digital, etc.)
• Quality Control: Prevents unrealistic dates through smart comparison logic

🏗 Current Architecture

Core Components:

• nfoguard.py - Main FastAPI webhook server
• clients/radarr_db_client.py - Direct database access client
• clients/external_clients.py - TMDB/OMDb integration
• core/nfo_manager.py - NFO file creation and management
• bulk_update_movies.py - Mass movie processing

Data Flow:

1. Radarr webhook → NFOGuard processes → Database queries for import dates
2. Smart fallback logic for manual imports → TMDB digital release dates
3. NFO file creation with preserved dates → File timestamp updates

🔧 Configuration Management

Environment-Based Setup:

• .env.template - Generic configuration template
• docker-compose.yml - Production deployment configuration
• Supports multiple media paths and database types

Key Settings:

• MOVIE_PRIORITY=import_then_digital - Prioritizes real import history
• PREFER_RELEASE_DATES_OVER_FILE_DATES=true - Smart fallback for manual imports
• RELEASE_DATE_PRIORITY=digital,physical,theatrical - Configurable fallback order
• Database connection parameters for PostgreSQL/SQLite

📊 Performance Metrics

Before (API-based):

• Took 30+ seconds for complex movies
• Failed on movies with extensive history
• API pagination caused timeouts

After (Database-only):

• Sub-second response times
• Handles any history size
• Reliable July 2025 date detection maintained

🧪 Testing Infrastructure

Comprehensive Test Suite:

• test_bulk_update.py - Database connection validation
• test_movie_scan.py - Directory scanning logic testing
• test_end_to_end.py - Complete workflow validation

Debug Endpoints:

• /debug/movie/{imdb_id} - Import date analysis
• /debug/movie/{imdb_id}/priority - Date selection logic
• /debug/movie/{imdb_id}/history - Complete import history

🎉 Success Metrics

Production Results:

• ✅ Correct July 2025 dates preserved for legitimate imports
• ✅ Manual imports now use intelligent release date selection:
  • "The Craft (1996)" → 1996 theatrical date (not 2025 file date)
  • "Top Gun Maverick (2022)" → digital release date per user preference
• ✅ Zero API timeout issues with database-only approach
• ✅ Complete webhook-based operation (no manual CLI required)
• ✅ NFO source annotations for full transparency

🚧 Current Development Focus

Completed (v0.6.0):

• ✅ Revolutionary Priority System: Configurable digital/physical/theatrical fallbacks
• ✅ Per-Movie Intelligence: Adapts to movie era and available release data
• ✅ Complete Documentation: README, testing guides, troubleshooting
• ✅ Source Transparency: NFO annotations show exactly which source was used

Next Priorities:

• TV series processing optimization
• Additional external API integrations (OMDb, Jellyseerr)
• Advanced configuration options
• Community feedback integration

📈 Project Maturity

Ready for Production:

• ✅ Stable database architecture
