Scope fence – read before use A PASS verdict proves: the pasted document's proof block is a valid eddsa-jcs-2022 Ed25519 signature over the JCS-canonicalized document (minus proofValue), verified against the Ed25519 key decoded directly from the did:key named in verificationMethod; and every nested receipt's execution_hash independently recomputes from its own policy_parameters/output_payload via the same canonicalizer chaingraph/kernels/_hash.mjs uses. It does not prove a human reviewed the artifact – a valid signature is a machine-signing fact only (see the attestation_grade row below), and it does not prove the did:key belongs to any particular organization, since did:key is self-certifying by construction with no registry.
