Every receipt has a fingerprint. If anyone changes the receipt, the fingerprint no longer matches.
Each card below is a separate Zambo job. These three examples are independent records, not one combined job.
A public receipt records the tool result and links to the original run so you can inspect it.
A match means the saved result is unchanged from the record being checked.
It does not prove the answer is correct, the source data is accurate or current, or an outside action happened.
