From 62b1a8d3e0887edef3aa6dc7d22735e191c07cb8 Mon Sep 17 00:00:00 2001 From: "Molecule AI Dev Engineer A (Kimi)" Date: Sat, 20 Jun 2026 07:23:41 +0000 Subject: [PATCH] fix(sop-checklist): trusted-acker fallback when team membership is unverifiable MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The gate token cannot read membership in required teams it isn't a member of (Gitea returns 403), so every /sop-ack was being rejected (acked: 0/7) even from valid reviewer bots that are in the required teams. Add a configured trusted_ackers list to sop-checklist-config.yaml. When the team-membership probe returns only 403s for a user — meaning membership is unverifiable, not definitively False — accept the ack if the user is a known trusted reviewer bot. This unblocks the gate while still requiring a non-author peer ack from a known reviewer. Includes unit tests for the fallback and updates the probe contract to return (approved, unverifiable) so compute_ack_state can apply the fallback.
