## Delivery and idempotency handling

* Use `data.id` as the primary idempotency key combined with `data.start_time` to distinguish reschedule events.
* `data.start_time` and `data.end_time` reflect the new scheduled times in milliseconds.
* Update any calendar syncs or downstream reminders when this event fires.
