Run the verification in your browser. The receipt JSON and the published public key are the only inputs needed.

Spec: ep-receipt/2026-04-27
Algorithm: ES256
Canonicalisation: RFC 8785 JCS
Public keys: /.well-known/jwks.json

Open in /verify Run the 80-line Python verifier

Without an execution layer

✗ Action either runs unchecked or fails opaquely
✗ No third party can confirm what happened
✗ The audit trail is whoever the issuer says it is

With Execution Protocol

✓ Every action passes a deterministic policy gate
✓ Every terminal state emits a signed receipt
✓ Anyone with the public key can verify offline

The model can hallucinate. The execution layer cannot.
