review.completed
Fires once when a review ends with every planned deep check done. The body is ReviewWebhookPayload, not WebhookPayload: switch on event and dedupe on event_id. A review's own deep checks fire no verification.* events.

Payload
Response
Your endpoint should return 2xx within 5 seconds. Non-2xx triggers retries at 10s / 60s / 600s (3 retries after the initial delivery, 4 attempts total).
Changes
Webhooks have no change history: a webhook is keyed by its event name rather than a path and method, so no recorded change can name it.
