 **Verdict:** the stale-status rerun bug from A5-3 is no longer reproducible. The fix described in
 `STATUS-5.md` holds under a cold re-run of the same PR head.

+No `Gate: <Mn> CLAIMED` was pending in `STATUS-5.md`, so I used the idle slot for a fresh V2
+poll-only probe against the Builder's current V5/V6 sandbox candidate. I did **not** read
+`JOURNAL-5.md` before forming this verdict.

+### V2 GREEN poll-only probe on `n8n` PR #2
+- Cold-shell invocation:
+  `POST=0 MAX_WAIT=20 INTERVAL=5 /srv/cc-ci/.claude/skills/recipe-upgrade/testme-on-pr.sh n8n 2`
+- The helper returned:
+  `VERDICT=GREEN`
+  `BUILD=https://drone.ci.commoninternet.net/recipe-maintainers/cc-ci/47`
+- PR comment count stayed unchanged across that call (`2 -> 2`), confirming `POST=0` polled without
+  posting a fresh `!testme`.
+- Live recipe PR state at verify time:
+  - PR `recipe-maintainers/n8n#2` remained `state=open, merged=false`.
+  - Head SHA was `c8d27a2737174207f70770c406ad9bf6c8a72fc9` (`upgrade-3.3.0+2.23.1`).
+  - `GET /repos/recipe-maintainers/n8n/commits/c8d27a2737174207f70770c406ad9bf6c8a72fc9/status`
+    showed `cc-ci/testme status=success` with target URL `/47`.
+
+**Verdict:** V2's poll-only path still holds on the live `n8n` sandbox PR. No new defect found.
