Active Record patterns¶

Production Rails usually needs discipline:

• N+1: eager load with includes / preload; monitor with Bullet in dev.
• Transactions: wrap multi-row updates; avoid long-held transactions open during I/O.
• Scopes: composable named scopes beat giant query objects for readability.
• Migrations: reversible where possible; index additions in separate deploy steps at scale.

These map loosely to Astra's transactional task transitions and Postgres as source of truth — same database rigour, different runtime shape.
