Receipt history
World Model MCP
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.
No receipt has been issued for this listing yet.
No receipt has been issued anywhere on this site yet. A receipt is signed with the site's published key, and no signing key has been published, so none can be issued until one is.
This listing was found in a public registry and read by the catalogue's own scan, which is shown on its page with the exact digest or commit it read. That reading is not a signed receipt: receipts are issued to versions a maker submits for verification.
