In short

Ask the execution system to preserve the tool call and the result it observed. A verifiable receipt gives a reviewer a stable record to inspect and check.

Collect evidence at the point of execution

For each claimed action, retain the tool name, time, relevant input and output, and a receipt link. For an external change, also obtain confirmation from the system that owns that state.

What a verifiable receipt does not prove

A receipt is evidence about the saved execution record, not a blanket certification of the agent's reasoning or the overall task outcome.

Next step

Check a saved record with the public receipt verifier.
