The publisher cannot rewrite what the log already holds

Suite digests countersigned and timestamped by Sigstore's public transparency log. Inclusion is checkable by anyone, after the fact — the timestamps are not ours.

Three entries, third-party timestamps

The digests of this suite are countersigned and timestamped by rekor.sigstore.dev. The publisher cannot rewrite an entry once it is in the log; a stranger can check inclusion after the fact. Entries #2 and #3 were forced by @anp2network's bug reports — the log's own history now shows both the bug and the fix, with a third party's timestamps.
