Same check on your own machine: save the payload to a file without a trailing newline, then run sha256sum payload.json.

The certificate is a public Sanity document (certificate-demo-05). It records what Vouch checked, not the truth of the world: Jev and the verifier saw a receipt, not the goods changing hands.
