## 📋 Pending Tasks

### Models (Priority: Critical)
Need to copy and adapt from v1 with improvements:

1. **User Model** - Add indexes on username
2. **Player Model** - Add indexes on auth_code, group_id, last_seen
3. **Group Model** - Add indexes on name
4. **Content Model** - Add indexes on content_type, position, uploaded_at
5. **ServerLog Model** - Add indexes on level, timestamp
6. **PlayerFeedback Model** - Add indexes on player_id, timestamp
7. **Association Tables** - group_content for many-to-many relationship

### Utils (Priority: Critical)
Need to copy and adapt from v1 with type hints:

1. **logger.py** - Logging utility with type hints
2. **uploads.py** - File upload utilities with progress tracking
3. **group_player_management.py** - Group/player management functions
4. **pptx_converter.py** - PowerPoint conversion utility

### Templates (Priority: High)
Need to copy from v1 and update route references:

1. Update all `url_for()` calls to use blueprint naming:
   - `url_for('login')` → `url_for('auth.login')`
   - `url_for('dashboard')` → `url_for('main.dashboard')`
   - `url_for('add_player')` → `url_for('players.add_player')`
   - etc.

2. Organize templates into subdirectories:
   - `auth/` - login.html, register.html
   - `admin/` - admin.html
   - `players/` - players_list.html, add_player.html, edit_player.html, player_page.html, player_fullscreen.html
   - `groups/` - groups_list.html, create_group.html, edit_group.html, manage_group.html, group_fullscreen.html
   - `content/` - content_list.html, upload_content.html, edit_content.html
   - `errors/` - 404.html, 403.html, 500.html
   - `base.html` - Main layout template

### Docker Configuration (Priority: High)
1. **Dockerfile** - Multi-stage build targeting 800MB
2. **docker-compose.yml** - Services: digiserver, redis, optional worker
3. **nginx.conf** - Reverse proxy configuration
4. **.dockerignore** - Docker ignore patterns

### Testing (Priority: Medium)
1. **tests/conftest.py** - Test fixtures
2. **tests/test_auth.py** - Authentication tests
3. **tests/test_players.py** - Player management tests
4. **tests/test_groups.py** - Group management tests
5. **tests/test_content.py** - Content management tests
6. **tests/test_api.py** - API endpoint tests

### Git Repository (Priority: Medium)
1. Initialize Git repository
2. Create initial commit
3. Push to remote (if desired)

---

## 🎯 Next Steps

### Immediate Actions
1. **Copy models from v1** - Add to `app/models/` with:
   - Type hints
   - Database indexes
   - Proper relationships
   - `__repr__` methods

2. **Copy utils from v1** - Add to `app/utils/` with:
   - Type hints
   - Improved error handling
   - Documentation

3. **Create model init file** - `app/models/__init__.py` to export all models

### After Models/Utils
4. **Copy templates from v1** - Update route references to blueprint naming
5. **Create Docker configuration** - Multi-stage build with optimization
6. **Test application** - Ensure all routes work correctly
7. **Initialize Git** - Create repository and initial commit

## 📝 Notes

### Architecture Decisions
- **Blueprint organization**: Logical separation by functionality
- **Caching strategy**: Redis for production, SimpleCache for development
- **Authentication**: Flask-Login for web, Bearer tokens for API
- **Rate limiting**: In-memory for now, should use Redis in production
- **File uploads**: Direct save with progress tracking, can add Celery for async processing

### Optimization Opportunities
- Add Celery for async video processing
- Implement WebSocket for real-time player updates
- Add comprehensive database migrations
- Implement API versioning (v1, v2)
- Add comprehensive test coverage
- Add Sentry for error tracking

### Migration from v1
When copying from v1, remember to:
- Update all route references to blueprint naming
- Add type hints to all functions
- Add database indexes for performance
- Update imports to match new structure
- Update static file paths in templates
- Test all functionality thoroughly

## 🚀 Ready for Next Phase

The blueprint architecture is now **fully implemented** with all 6 blueprints:
- ✅ main (dashboard, health)
- ✅ auth (login, register, logout)
- ✅ admin (user management, system settings)
- ✅ players (CRUD, fullscreen, bulk ops)
- ✅ groups (CRUD, manage, fullscreen)
- ✅ content (upload, manage, API)
- ✅ api (REST endpoints, authentication, rate limiting)

**Ready to proceed with models and utils migration!**
