Verify DOI metadata before autonomous action; preserve conflicts, provenance, and UNKNOWN.

Pre-action evidence gate for Crossref records whose record type is standard: determine what the currently available technical/industry-standard DOI metadata supports before an autonomous system cites, stores, publishes, ingests, or otherwise acts, while preserving provenance, conflicts, unresolved evidence, and explicit UNKNOWN. Use when a downstream action depends on a supported metadata fact for a Crossref standard-type DOI record and the record may be stale, incomplete, conflicting, or insufficient; when publication status, supersession, revision, adoption, approval date, designator, standards-body metadata, title, DOI, edition, or metadata surface must be checked before action; or when provenance and explicit UNKNOWN handling matter. Do not use for ordinary journal articles, citation validation, retraction checking, scholarly literature verification, or general multi-provider DOI resolution. Also do not use when raw Crossref metadata alone is sufficient, or to establish scientific truth, claim validity, legal or regulatory authority, open-ended literature search, historical reconstruction, unsupported identifier families, general fact verification, or mutation.
Exact Crossref standard-type DOI source identifier, for example crossref:doi:<DOI>. Ordinary journal-article DOI records are outside the current capability.
Exact supported technical-standard metadata fact predicate whose current evidence-supported state must be checked. See the capability beacon supported_scope.predicates list.
Optional ISO-8601 date/timestamp. Omission is carried as a separate flag so the runtime may use the current materialised observation.
