Each card states its own C.16 well-formedness fields: characteristic, scale, unit or unitless interpretation, declared measurement basis, comparability basis, evidence relation, evidence-provenance relation, source relation, or evidence-claim-absent reason, non-admissible use, and repair action. When source material is used as evidence, the source relation is named. A source checklist, source-discharge slice, dashboard label, or inherited score is not enough.
