description: "Re-verifies a conversion receipt from art-191: recomputes binding_sha256 over the JCS-canonical receipt and compares, checks structure and hex fields, and optionally compares digests re-hashed from the actual files. Returns a verdict of valid, binding_mismatch, digest_mismatch, or malformed, plus a per-check detail list. This verifies the domain receipt inside the artifact, which is distinct from verify_execution_hash, the utility that verifies the section 4 artifact envelope. Zero network, zero PII."
