WHY IT NEEDS A POLICY

Why cancel_calendar_attendance needs a policy

Cancelling a calendar attendance modifies/updates an existing record (changing attendance status from active to cancelled). This is reversible in principle (attendance could potentially be re-created or re-confirmed), placing it in Write rather than Destructive. The blast radius is medium as it affects scheduling and coordination for other participants.
