Verify a Seal

A Seal is OpenAdapt Cloud’s Ed25519 signature on a run’s evidence receipt. Paste the receipt JSON (on its own, inside a run report, or inside a webhook body) to check that OpenAdapt Cloud signed it and that nothing in it changed since. The receipt holds digests and outcomes, not screenshots or entered values.
