Match each claim to its evidence

A tool call receipt can show what the tool system recorded. If the task depends on a change in another system, inspect that system's own confirmation as well.

What a verifiable receipt does not prove

A receipt is not proof of every task outcome. It cannot establish an external action that the receipt did not observe.

Next step

Check a saved record with the public receipt verifier.
