In short

Proof of execution is a claim that an action ran, while a verifiable receipt is an artifact a reviewer can inspect. The receipt supports only the execution and observations present in its record.

Keep the claim and artifact distinct

A completion statement describes what an agent says happened. A receipt supplies a separate record of the tool call and the result the execution system observed.

What a verifiable receipt does not prove

A receipt cannot establish an outcome beyond its recorded evidence. Check external state with the system that owns it.

Next step

Check a saved record with the public receipt verifier.
