historical validity and current endorsement are separate predicates

Agent-decided. A process must be able to say that something really was a reason it incurred under its then-legitimate standards while rejecting its force now; what it must not be able to say is that because the standards changed there never was an answerability relation. Requiring current endorsement for historical answerability would collapse the two and make every standards change a laundering opportunity, so the theorem depends on the first predicate only and the two are allowed to diverge.
