This project contains a number of examples and test cases for the IETF SCITT WG specification.
This is a Signed Statement using COSE Hash Envelope, produced by a Microsoft issuer, and made transparent in test DataTrails and Microsoft ledgers.
The Signed Statement commits to the digest of an in-toto Statement (application/vnd.in-toto+json) describing the Phi-4-reasoning model. The CWT subject is experimental/microsoft/phi-4-reasoning, and the issuer is identified by a did:x509 with the Microsoft Signing Transparency EKU 1.3.6.1.4.1.311.76.59.1.1. The in-toto manifest and recreation steps are documented at https://github.com/achamayou/scitt-for-phi.
Two Transparent Statements, embedding respectively one and two receipts are available.
