- Prevents circular dependency where login requires session, but session requires database table created by migrations - Fresh installs: use file session until migrations run, then switch to database session - Upgrades: use file session during migration, then switch to database session - Ensures sessions table exists before using database session handler Fixes: Sessions table missing on fresh install prevents login
