+# #3141 (CTO-authorized): make the three review-team gates TRULY merge-blocking.
+# Today they post commit statuses but are NOT in BP, so a PR merges once its 4
+# BP-required contexts are green regardless of the review verdicts (proven: #3131
+# merged with qa-review red).
+#
+# MECHANISM — Path B (owner BP flip) is the ONLY option; Path A (sentinel) is
+# structurally impossible: `CI / all-required` is a plain `needs:` aggregator
+# over CI's OWN jobs (ci.yml). Gitea has no cross-workflow `needs:`, and the
+# poll-the-status-API design was deliberately removed (runner-squat RCA
+# 2026-06-01). These three contexts are emitted by SEPARATE workflow files on
+# pull_request_target / pull_request_review events, so the sentinel cannot gate
+# them — which is exactly why ci-required-drift.py F4 enforces cross-workflow
+# required contexts in BP directly.
+#
+# BP variant = (pull_request_target): it fires on every PR open/synchronize and
+# starts RED when there is no APPROVE (review-check.sh exits 1 → job conclusion
+# publishes `failure`) — fail-closed, no false-green, no deadlock. The
+# pull_request_review path explicitly RE-POSTS the (pull_request_target) context
+# to flip green on a genuine non-author APPROVE (same shape as sop-checklist).
+# Requiring (pull_request_review) instead would deadlock (absent-until-review =
+# pending forever).
+#
+# REMAINING OWNER ACTION: after THIS PR merges, PATCH
+# branch_protections/main.status_check_contexts to ADD the three
+# `(pull_request_target)` variants of the contexts below (keep the existing 4).
+# Allowlist-superset-of-BP is lint-clean; BP-superset-of-allowlist is not — so
+# the allowlist (this file) MUST land first, BP flip second. See #3141.
