 - [x] [adversary] **[A1] Build #585 must NOT be used as the "clean post-proxy pass"** — it ran pre-proxy (03:59Z vs proxy fix at 05:38Z) and tested PR#5 (cfold probe), not PR#4. A genuine post-proxy !testme on PR#4 is required for M1. @2026-06-13T06:22Z — **CLOSED: Builder used build #612 (post-proxy, 06:13Z), not #585. M1 PASS @06:38Z**
 - [x] [adversary] **[A2] `update_config.monitor` is likely the root cause of upgrade timing failures** — builds #557 and #578 both failed with `UpdateStatus=paused`, NOT VIP exhaustion. @2026-06-13T06:22Z — **CLOSED: Build #612 passed post-proxy confirming infra-confound. Operator comment explains MySQL timing under load. M1+M2 PASS @06:38Z**
 - [x] [adversary] **[A3] PR#5 (cfold probe) should be closed once PR#4 has its verdict** — not the canonical upgrade. @2026-06-13T06:22Z — **CLOSED: PR#5 closed (verified). M2 PASS @06:38Z**

+- Cold Gitea inventory shows exactly one open Ghost upgrade PR: PR#8, head
+  `dbe40ecb7b0084050a71baf4dcf971b65aac125e` on `upgrade-ee04ca9`; PRs #1-#7 are closed.
+- Gitea comments #16297 and #16298 show the fresh `!testme` and its result for build #66.
+- Drone API build #66 independently reports `status=success`, `RECIPE=ghost`, `PR=8`,
+  `REF=dbe40ecb7b0084050a71baf4dcf971b65aac125e`, and `SRC=recipe-maintainers/ghost`.
+- Host artifact `/var/lib/cc-ci-runs/66/results.json` reports `level=5`, with install,
+  upgrade, backup, restore, custom, and lint all `pass`; no unintentional skips are present.
+- The current evidence is post-proxy and uses the current PR head. The historical failed
+  artifacts remain separate: builds #515/#517 failed at install and #519/#557 failed at
+  upgrade, while the proxy was subsequently fixed to `10.10.0.0/16`; they were not used as
+  evidence against the current retry.
+
+### M2: PASS @2026-10-20T03:22:00Z

+- Exactly one relevant open Ghost upgrade PR remains, PR#8; all historical PRs #1-#7 are closed.
+- The operator-facing result comment #16298 links build #66 and reports the successful result.
+- Artifact flags are `clean_teardown=true` and `no_secret_leak=true`; `docker stack ls`,
+  `docker service ls`, `docker volume ls`, and `docker network ls` probes found no
+  `ghos-*` or `dev-ghost` resources. The proxy subnet is `10.10.0.0/16`.
+- The prior M2 veto is cleared: build #66 has a verified lint `pass`, unlike build #55's
+  unintentional lint `unver` result.
+
+**Fresh verdict:** M1 and M2 PASS. The current Ghost upgrade PR is operator-ready, the
+post-proxy retry is a genuine level-5 pass for the current head, historical failures remain
+separate from current recipe evidence, and no Ghost resources leak.
