065-declared-fail-closed-refusal

A fail-closed screen's refusal of hostile content is declared, not a breach of spec 025's invariant

Amends spec 025. Invariant I-1 says no byte of untrusted content changes a Statecraft decision, evidence admission included; spec 014's secret screen refuses evidence whose content looks like a credential. A corpus case may therefore declare one refusal from a closed list, naming the decisions it is carried into and the recordings it leaves empty; those may differ from the twin's only as that refusal, and every other difference still fails. A refusal only withholds; nothing here lets content expand authority.
