nist.material_properties

The version is immutable: the content at this address never changes.

The descriptor below is exactly the record the resolver puts into law.lock. Its shape is normative ($defs/LockedPackage of the lockfile schema), so publication status is expressed by the section of the catalogue rather than by a field inside it: an extra field would make the descriptor invalid.

Signature

Not issued. The field schema exists (signature: algorithm, keyId, value); an issuer and keys do not: a signature attests the provenance of the bytes, not the legal correctness of the rules, and is a separate piece of work.
