humanproof-verify0.3.02026-09-24The verifier reads the access receipt and the checkpoint of both chains
Third release with binaries for Linux, macOS and Windows, each with a checksum.
A batch may carry act receipts and evidence access receipts; the verifier groups them by format and by client and checks the chain of each group. The report says who opened, by role and opaque id, the outcome of each opening and when. Never the reason, only its hash, which whoever holds the text checks with a subcommand.
Version 2 of the checkpoint states both chains, acts and accesses, and each is checked against what the checkpoint says about it. A version 1 checkpoint on a batch with accesses does not approve by omission.
The report also comes out as a self-contained page, no script and no network, for whoever audits to keep next to the batch and print to PDF. It says what the text says, in the same sentences.
