Historical trust features reconciled

Earlier HDF-era ideas survive only where current evidence and terminology support them.

Provenance

Represented as declared source and revision evidence; it does not prove the underlying event happened.

Online status is a separate current-state check, not part of offline integrity.

Custody events are evidence records; legal sufficiency depends on context and procedure.

Treated as historical naming, not current product claims or approved trust services.
