From e274cd9adeecc6a5232e2959fee1efc3fb35aa7a Mon Sep 17 00:00:00 2001 From: Cursor Agent Date: Thu, 29 Oct 2026 20:32:52 +0000 Subject: [PATCH 1/5] fix(plv): accept structural mandate label variants MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Recognize Mandate, User mandate, Principal instruction, and bare Principal mandate headers when they are real section headers, so an omitted model quote is not floored to 0.25. Labels inside quotes, tool output, or the proposed action do not count. Disagreeing sections fail closed, and a fabricated model quote is never replaced by a fallback span.
