Handling

Verify x-networked-signature against the raw body before you trust the request.

Answer any 2xx within 10 seconds and process the event afterwards.

Deduplicate on id: retries and resends carry the same id.

Ignore keys and event types you do not handle; keys may be added, never removed or renamed.
