The headline was 0%. The controls still failed.

A lexical classifier labels answers and refusals. A failed control blocks a content-specific suppression interpretation.

{"method": "every question is a family of meaning-preserving wordings; the family is the statistical unit; new refusals (answered->refused) are the erasure events; the standing alarm is a mixture supermartingale, so the lifetime false-alarm rate is bounded under unlimited peeking", "method_note": "Rates are family-level with Wilson 95% intervals. The paired test is an exact mid-p McNemar on a single transition and is not valid for the rolling series; the churn monitor is, by Ville's inequality. Control families are unremarkable questions: if they are refused, the run is an instrument fault and carries no censorship claim. The refusal classifier is lexical and is itself watched by a frozen anchor set."}

The method describes this dated suite, not model behaviour outside it.

Cross-model agreement does not identify a provider-side cause.

The seal proves the attestation was not rewritten. It does not prove the classifier was correct.

This is the nearest prior full sweep. The two full-sweep records are descriptively comparable, but they do not identify a model release, provider, or routing cause.
