# update_units_default_availability

Bulk-set the unit-level default calendar availability — the PMS "Default calendar availability" radio. Accepts an array
of `{unitId, status}` where `status` is `AVAILABLE` or `UNAVAILABLE`. Existing blocks and bookings on the calendar are
not affected; only the default that applies to new dates changes. Returns per-unit success/failure so partial failures
don't abort the batch.
