    "1": { "name": "Attach", "requires": "A machine-readable evidence object accompanies the claim, with a schema.org conformsTo edge to this spec." },

    "3": { "name": "Sign", "requires": "The content is signed with ed25519 over the RFC 8785 (JCS) canonical form of the evidence object; the public key is published under the site's /.well-known/." }

  "positioning": "KGP does not replace C2PA (media provenance), sigstore or SLSA (software artifacts), or schema.org ClaimReview (fact-check claims). It is the web-discoverable, schema.org-tied, badge-linked evidence layer for arbitrary web claims, self-hostable via /.well-known/.",
  "adoption": "Draft. Reference implementations across the Kinetic Gain estate are rolling out. There are no external adopters yet; this field will list only independently verifiable implementers."
