Attest case record

Verify the media bytes

This page verifies every signed record and renders its timeline offline — and every record can be toggled between the technical view and the plain-language family view (the “plain language (family)” tab on each card). Signed media digests are listed per record; to check the media bytes themselves, open verify.html (from the extracted pack folder) and drop every file from this pack onto it.

The transparency checkpoint

This pack also carries log_checkpoint.json — a signed Merkle tree head over the deployment's receipt log (RFC 6962-style), with an inclusion proof per pack receipt and, when present, cosignatures from independent witness deployments. This page verifies the records' signatures and chains; to prove each receipt was committed to the published log — and see which witnesses vouched for that head — drop the whole pack on verify.html or run attest verify. This page can't inline the checkpoint doc: the pack's verifier manifest signs this page's bytes before the checkpoint can be issued.

What this does and does not establish

A green result proves the signed records are intact and were issued under the pinned issuer key — integrity, not physical truth. It does not prove anyone was present, absent, or honest; it proves the evidence chain was not altered after signing.

Trust note: this page traveled inside the pack it checks — for a dispute that matters, re-verify the pack with a verifier obtained independently (the deployment's /verify-pack or a pinned verify_case.py).
