- Added SQLAlchemy 2.0 and Alembic 1.13 dependencies - Created models.py with Channel and VideoEntry ORM models - Created database.py for database configuration and session management - Initialized Alembic migration system with initial migration - Updated feed_parser.py with save_to_db() method for persistence - Updated main.py with database initialization and new API routes: - /api/feed now saves to database by default - /api/channels lists all tracked channels - /api/history/<channel_id> returns video history - Updated .gitignore to exclude database files - Updated CLAUDE.md with comprehensive ORM and migration documentation Database uses SQLite (yottob.db) with upsert logic to avoid duplicates. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
