+- `set -a; . /srv/cc-ci/.testenv; set +a; curl -s https://$GITEA_URL/api/v1/version` → `{"version":"1.24.2"}`
+- `getent ahostsv4 probe-12345.ci.commoninternet.net` → `91.98.47.73` (STREAM/DGRAM/RAW)

+V4 red side:
+- `POST=0 MAX_WAIT=15 INTERVAL=5 /srv/cc-ci/.claude/skills/recipe-upgrade/testme-on-pr.sh custom-html-tiny 5`
+  → `VERDICT=RED`
+  → `BUILD=https://drone.ci.commoninternet.net/recipe-maintainers/cc-ci/34`
+- `curl -fsSL https://ci.commoninternet.net/runs/34/results.json` → install=`pass`, upgrade=`fail`, clean_teardown=`true`, no_secret_leak=`true`
+
+V4 fix on cc-ci host (same recipe PR branch):

+Adversary follow-up:
+- `REVIEW-5.md` follow-up (`review(5)` commit `e87782a`) closed A5-1 and A5-2 after a fresh cold re-test.
+- `BUILDER-INBOX.md` noted that `POST=0` must be env-prefixed in `STATUS-5.md`; corrected here and the inbox is being consumed now.

+Next: V5 default stale-test case, then V6 `--with-tests`.
