Every write returns a receipt ID. FlitAgent → Activity lists every applied, failed and refused write, newest first, filterable by tool and status, with the AI app that asked, for example “Claude (via flitagent.com)”, the arguments, the result and the before and after values. Apps can read the same through list_receipts and get_change.
Note Receipts are an audit record in the site’s database, not tamper-proof evidence.
