 # NFOGuard Development Summary
 
-## Current Status: v1.3.7 - NFO XML Parsing Fix
+## Current Status: v1.3.8 - NFO Field Ordering Fix
 
-### Latest Updates (v1.3.7)
-- **� FIXED**: XML comment parsing error causing NFO creation to fail
-- **🔧 XML HANDLING**: Improved XML comment insertion and file writing
-- **✅ PRESERVATION**: Existing movie metadata properly preserved during updates
-- **🎯 ROBUST**: Better error handling for malformed XML files
+### Latest Updates (v1.3.8)
+- **🎯 FIELD ORDERING**: NFOGuard fields now append at bottom of existing NFO content
+- **📋 STRUCTURE**: Date fields (premiered, dateadded, lockdata) appear after all existing metadata
+- **✅ PRESERVATION**: All existing content (actors, plot, ratings, etc.) maintained in original order
+- **🧹 SMART CLEANUP**: Only removes NFOGuard-added elements, preserves existing uniqueid[tmdb]
 
-### NFO Update Process (Fixed)
-```
-1. ✅ Load existing movie.nfo (if exists)
-2. ✅ Parse and validate XML structure  
-3. ✅ Remove old NFOGuard elements to avoid duplicates
-4. ✅ Preserve all existing content (title, plot, cast, etc.)
-5. ✅ Add/update NFOGuard fields (dateadded, lockdata, uniqueid)
-6. ✅ Write properly formatted XML with comment
+### NFO Field Order (Fixed)
+**Now places NFOGuard fields at the bottom:**
+```xml
+<movie>
+  <!-- All existing Radarr/Jellyfin content preserved -->
+  <title>Movie Title</title>
+  <plot>Plot content...</plot>
+  <actor>...</actor>
+  <!-- ... all existing fields ... -->
+  
+  <!-- NFOGuard fields appended at bottom -->
+  <uniqueid type="imdb" default="true">tt8350360</uniqueid>
+  <premiered>2019-06-26</premiered>  <!-- only if missing -->
+  <dateadded>2025-09-14T13:45:54-04:00</dateadded>
+  <lockdata>true</lockdata>
+</movie>
 ```
 
-### Error Resolution
-- **v1.3.6**: XML comment handling caused `'()` error
-- **v1.3.7**: Fixed comment insertion and XML serialization
-- **Result**: NFO files now update correctly while preserving contentlopment Summary
+### Smart Element Management
+- ✅ Preserves existing `uniqueid[tmdb]` and other IDs
+- ✅ Only removes NFOGuard-managed `uniqueid[imdb]` to avoid duplicates
+- ✅ Appends new fields using `ET.SubElement()` for bottom placement
+- ✅ Maintains clean XML structure and formatting
 
-## Current Status: v1.3.3 - Database Migration & Path Validation Complete
-
-### Latest Updates (v1.3.3)
-- **� DATABASE**: Fixed missing `path` column migration in movies table
-- **✅ MIGRATION**: Automatic schema updates with graceful error handling
-- **🔍 VALIDATION**: Enhanced database migration with column existence checks
-- **🎯 COMPATIBILITY**: Backward compatibility with existing databases maintained
-
-### Path Mapping Success (v1.3.2-v1.3.3)
-- **🐛 CRITICAL**: Fixed substring matching bug (movies/movies6, tv/tv6)
-- **🎯 ALGORITHM**: Longest-path-first matching prevents incorrect mappings
-- **� DEBUG**: Comprehensive debug logging for troubleshooting
-- **✅ TESTED**: Annabelle webhook now processes correctly
-
-### Working Path Mapping Example
-```
-Radarr webhook: /mnt/unionfs/Media/Movies/movies6/Annabelle...
-✅ Sort by length: [movies6, movies] (longest first)
-✅ Match movies6: /mnt/unionfs/Media/Movies/movies6
-✅ Map to index 1: /media/Movies/movies6
-✅ Result: /media/Movies/movies6/Annabelle (2014) [tt3322940]
-✅ Path exists: Validation passes
-✅ Processing: Movie webhook succeeds
-```
-
-### 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
