+    # Closes the INV-FRESH gap (ADR-001): the BUILD-ONCE retag (ORCH-36) promotes
+    # the staging image to prod WITHOUT a rebuild, assuming the staging image is
+    # fresh — a guarantee the pipeline never had (a stale image could be silently
+    # promoted, LESSONS_ORCH-036 §4). Two complementary layers, self-hosting only:
+    #   A (liveness): the QG sub-check check_staging_image_fresh rebuilds the
+    #     staging image from the VALIDATED commit (worktree HEAD after merge-gate)
+    #     and recreates 8501 on the deploy-staging -> deploy edge, so we validate
+    #     and promote ONE artefact.
+    #   B (safety): build_deploy_command passes EXPECTED_REVISION and the hook
+    #     fail-closes (exit 1) if SOURCE_IMAGE's revision label != EXPECTED_REVISION
+    #     before `docker tag`, making a silent stale promote structurally impossible.
