✓ Accepted answer
Name the event as a completed business fact, then choose a stable key that keeps related events ordered. Include an event ID, event time, schema version, producer, and the smallest useful business payload. Document compatibility expectations before adding consumers, and design consumption to be idempotent so replay is safe.
