Upload / PMS Sync

The API accepts either format. https://ca.hyatt.com/... matrix or {hotelCode,businessDate,rooms:[]}. On real deploys, your external process will POST to /api/pms/sync.

• If a serviced/checked-out room becomes vacant dirty → a new follow-up task is created (reason EARLY_DEPARTURE or REDIRTY_AFTER_COMPLETION).
• If a new workload appears after assignment, the task keeps its housekeeper until a manager explicitly returns it to the pool.
• PMS/board mismatches create discrepancies (visible on Reconciliation & All Rooms).
• If the board is locked, the sync is recorded but board rows aren't changed — unlock the board first.
• Old PMS snapshots are rejected if generatedAt is older than last sync.
