From 35bc14d0aa7e084f2679652db990329b71ede228 Mon Sep 17 00:00:00 2001 From: coderdailyone Date: Wed, 26 Aug 2026 05:17:20 -0700 Subject: [PATCH] security: negated denials ("no, don't approve") no longer resolve as allow MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit resolve_from_reply tested allow words before deny words, so a refusal phrased around an allow word released the one-shot approval as ALLOW: "no, don't approve" → matched \bapprove\b first → allow "not allowed" → contains no deny word at all → allow The gate now fails closed: deny words win on mixed phrasings, and an allow word preceded by a negator (not / never / -n't) counts as a refusal. Free-text answers to questions are unaffected.
