Bind a declared edge to both pinned endpoints and the exact owner/subject frame. Unresolved targets, wrong digests and cycles remain negative evidence, not independent provenance verification for caller-supplied artifact and dataset provenance manifests. No source download, build reproduction, signature verification, proof of origin, causality or scientific validity. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.
