Group matching owner/subject/revision frames and distinguish repeated pins from conflicting content pins 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.

Group matching owner/subject/revision frames and distinguish repeated pins from conflicting content pins for nonpersonal work and permission-manifest metadata. No authoritative license interpretation, rights clearance, agreement acceptance, royalty transfer or legal advice. Satisfied conditions are caller declarations only. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.

Group matching owner/subject/revision frames and distinguish repeated pins from conflicting content pins for caller-supplied package release and file-inventory manifests. Manifest revision lineage only, not a resolved package dependency graph. No registry lookup, download, installation, code execution, vulnerability scan, publisher authentication or software-safety certification. Input limit: 32 KiB. Result retention: 24 hours; minimal receipt metadata: 90 days.

Group circuit/backend/revision frames and distinguish exact pinned duplicates from conflicts in operation digest, register size or scope. Ingestion IDs are not circuit identity. Caller-supplied public/synthetic nonpersonal metadata only. No quantum simulation, device/API access, execution, calibration measurement, scientific validation or claim of circuit equivalence. Input limit: 32 KiB. Result retention: 24 hours; minimal receipt metadata: 90 days.

Group exact backend/run/revision frames; conflicting measurement, scope or register-size pins are separate from repeated projections. Ingestion IDs do not identify calibration runs. Caller-supplied public/synthetic nonpersonal calibration declarations only. No hardware measurement, device/API access, recalibration, mitigation, performance guarantee or scientific certification. Input limit: 32 KiB. Result retention: 24 hours; minimal receipt metadata: 90 days.
