The hourly `expireSessions()` cron runs `DELETE FROM planner.sessions WHERE last_activity < cutoff`. Without an index on `last_activity`, that's a full table scan growing linearly with the total sessions ever created (planner sessions are never user-deleted; expiry is the only churn path). `drizzle-kit push` picks this up on next deploy.
