Receipt history

Zibby MCP CLI

Every signed receipt issued for every version of this listing, kept public, with what changed from one version to the next. Each one is checked against its Ed25519 signature before anything it says is shown here, and each downloads as the signed JSON it is, so it can be verified without this site.

What this does not cover: a receipt is true for the version, rubric and date it names, and nothing later. A regression below is a change between two signed results, not a finding about how the software is used.

The receipt registry did not answer, so this page shows nothing rather than a copy it cannot check. Try again shortly.
