Specimen ledgers
The record as it stands, for one asset at a time.
A team with a submission date, a coverage review or a transaction closing gets the record about its asset as it stands: every act the deciding institutions have recorded, each dated to the day its source carries, tied to an archived copy by its digest, and chained so an edit anywhere shows.
A specimen is a real ledger, published so a buyer can see the shape of the deliverable before commissioning one. Nothing on a ledger is estimated; the registered record an asset may also have lives on its own page and is linked, not restated.
