From 9ede993f3d8e60893fb5dbda6b11c4f89cff75e8 Mon Sep 17 00:00:00 2001 From: Molecule AI Core-DevOps Date: Sun, 17 May 2026 05:09:35 +0000 Subject: [PATCH 1/2] fix(sop-checklist): probe() KeyError for gate names in compute_na_state MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit compute_na_state() calls probe(gate_name, [user]) where gate_name is a gate name like 'qa-review' or 'security-review' — these are not checklist item slugs and are not in items_by_slug. probe() was doing: item = items_by_slug[slug] # KeyError for 'qa-review' This caused the sop-checklist workflow to crash on any PR that has N/A gates configured (all 7 checklist items with /sop-n/a), producing a 30-minute Failing status before Gitea kills the job. Fix: add _required_teams_for() helper that falls back to na_gates lookup when slug is not in items_by_slug. Gate names resolve to their required_teams from the n/a_gates config section. Adds TestProbeNaGateFallback regression test (58/58 passing).

Fix: catch ApiError specifically around merge_pull(), post a PR comment with the error detail and a reference to SEV-1 internal#487, and return exit code 2 so the workflow run is marked failed. Exit codes: 0 — success (merged, updated, or nothing to do) 2 — merge API error (permission/hook issue, non-transient) Fixes: SEV-1 internal#487 — queue silently failing to merge while reporting success; merge permission error invisible without workflow log inspection.
