# SamCloud Music - Development Progress Log

## Session: July 1, 2025

### 🎯 SESSION GOALS
- [x] Create comprehensive backup system
- [x] Fix library loading uninitialized variable error  
- [ ] Resolve Jellyfin authentication localStorage issues
- [ ] Test complete music library browsing workflow
- [ ] Document working state for future reference

### 📝 PROGRESS LOG

#### 05:08 - Complete Project Backup Created ✅
- **Action**: Created full backup at `/Volumes/SamMgmt/Containers/SpotSpot/Backup/SamCloud_Music_20250701_050806`
- **Files**: Complete project structure with documentation
- **Size**: 1280 items backed up
- **Status**: ✅ Complete and recoverable

#### 05:09 - Current Issues Identified
- **Library Error**: Uninitialized variable at line 3262 in `index.html`
- **localStorage Problem**: Incorrect Jellyfin server URL cached from previous testing
- **Source Maps**: Missing socket.io map files (404 errors)

#### 05:10 - Fixed Uninitialized Variable Error ✅
- **Action**: Fixed duplicate `const libraryCount` declarations in `loadLibrary()` and `loadLibraryData()` functions
- **Root Cause**: Variable was declared twice causing "Cannot access uninitialized variable" error
- **Solution**: Removed duplicate declaration and moved `libraryCount` reference to within the appropriate scope
- **Status**: Container restarted, JavaScript error should be resolved
- **Test**: App opened in browser for verification

### 🐛 CURRENT BUGS TO FIX

1. **Priority 1**: ~~JavaScript `ReferenceError: Cannot access uninitialized variable`~~ ✅ **FIXED**
   - **Location**: `backend/templates/index.html:3262`
   - **Impact**: Prevents library from loading
   - **Status**: Resolved - duplicate variable declarations removed

2. **Priority 2**: Jellyfin authentication localStorage mismatch  
   - **Issue**: Cached wrong server URL (`jellyfin.sammgmt.com` vs `jellyfin.samcloud.ca`)
   - **Solution**: Reset settings button added, needs testing
   - **Next**: Test reset functionality and correct authentication

3. **Priority 3**: Missing source maps (cosmetic)
   - **Files**: `socket.io.min.js.map`
   - **Impact**: Console 404 errors (non-functional)
   - **Next**: Add proper source maps or use non-minified version

### 📋 TODO LIST

#### Immediate (Today)
- [x] Debug and fix uninitialized variable in library loading ✅
- [ ] Test localStorage reset functionality
