Guide
Never publish a render before you verify the artifact.
Terminal webhooks mean the job finished — not that your CDN object is safe to show. Check checksum, content type, and URL expiry before user-visible publish.
- Handle the signed webhook idempotently.
- Fetch artifact metadata and compare checksum/content-type.
- Only then copy/promote into your delivery bucket.
- If verification fails, surface an internal retry — do not show a partial file.
