Tables fixed: - rooms → added updated_at - housekeeping_tasks → added updated_at - channels → added created_at + updated_at Trigger function set_updated_at() attached to all 6 tables (hotels, users, rooms, bookings, housekeeping_tasks, channels) — updated_at now auto-sets on every UPDATE via BEFORE UPDATE trigger. Indexes added for archiving / range queries: - bookings(hotel_id, created_at), bookings(hotel_id, updated_at) - housekeeping_tasks(hotel_id, created_at) - rooms(hotel_id, updated_at) - channels(hotel_id, updated_at) Also patched 001_schema.sql so fresh installs start correct. Migration runner is idempotent — skips already applied files. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
