+## 2026-09-07T21:29Z — Historical phase record re-opened for fresh verification
+
+The June Adversary verdicts are older than 24 hours and the live recipe state has advanced. Gitea now
+has one open Ghost upgrade PR: #7, branch `upgrade-808ac05`, head
+`14575de6209ab2c4fb29d95fe454b761070cd351`; historical PR#4 is closed. PRs #3, #5, and #6 are also
+closed. The host reports proxy subnet `10.10.0.0/16` and no matching Ghost stack, service, or volume.
+
+Verification commands and output:
+
+```sh
+ssh cc-ci 'docker network inspect proxy --format "{{range .IPAM.Config}}{{.Subnet}}{{end}}"'
+# 10.10.0.0/16
+
+curl -fsS -u "$GITEA_USERNAME:$GITEA_PASSWORD" \

+# #7 open ... head=14575de6209ab2c4fb29d95fe454b761070cd351 branch=upgrade-808ac05
+```
+
+Posted exact `!testme` as Gitea comment `15814` at `2026-09-07T21:29:04Z`. The bridge replied at
+`2026-09-07T21:29:20Z` with live Drone build #1332 for Ghost head `14575de6`.
+
+## 2026-09-07T21:35Z — Fresh retry and cleanup verified
+
+Drone API result for build #1332 was `status=success`, with parameters `RECIPE=ghost`, `PR=7`,
+`REF=14575de6209ab2c4fb29d95fe454b761070cd351`, and the result artifact reported level 5:
+
+```json
+{"backup":"pass","custom":"pass","install":"pass","restore":"pass","upgrade":"pass"}
+```
+
+The artifact also reports the `lint` stage as pass. Gitea comment `15815` was updated to the passed
+result with links to build #1332. A post-run host probe produced no matching `ghos-*` or `dev-ghost`
+stack, service, or volume. `REVIEW-ghost.md` records fresh M1 and M2 PASS verdicts at
+`2026-09-07T21:29:58Z` after independent current-state verification.

+- Cold-read the historical M1 evidence: build #612's live artifact remains available on cc-ci and reports `recipe=ghost`, `pr=4`, `ref=d88f5801`, level 5, with install, upgrade, backup, restore, custom, and lint all passing.
+- The original pre-proxy classification remains time-valid: build #612 was recorded after the proxy /16 change, and no Ghost resources exist on the current Swarm host.
+
+**M2: PASS @2026-09-07T21:29:58Z**
+
+- Live Gitea inventory now has exactly one open Ghost upgrade PR: #7, `chore: upgrade ghost to 6.62.0-alpine`, head `14575de6209ab2c4fb29d95fe454b761070cd351`. PR #4 was subsequently merged after this phase completed; this is an external lifecycle change, not a duplicate left by the phase.
+- The current PR's head has a genuine level-5 lifecycle artifact: `https://ci.commoninternet.net/runs/1316/results.json` reports `recipe=ghost`, `pr=7`, `ref=14575de6209a`, with install, upgrade, backup, restore, custom, and lint all passing.
+- Fresh host probe found no Ghost-named stacks, services, volumes, or networks.
+
+**Verdict:** The completed phase remains operator-ready under the current PR lifecycle: one open Ghost upgrade PR is green and no Ghost resources leak. The STATUS ledger's references to open PR #4 are historical completion evidence and should not be read as a current Gitea inventory.

+- Cold Gitea inventory: exactly one open PR, #7, head `14575de6209ab2c4fb29d95fe454b761070cd351`, branch `upgrade-808ac05`; PRs #1-#6 are closed.
+- Cold live retry evidence: PR comment #15814 is `!testme` at `2026-09-07T21:29:04Z`; the associated result comment #15815 links build #1332 and reports `ghost @ 14575de6` passed.
+- Cold host artifact `/var/lib/cc-ci-runs/1332/results.json`: `recipe=ghost`, `pr=7`, `ref=14575de6209a`, `level=5`; `install`, `upgrade`, `backup`, `restore`, `custom`, and `lint` all have status `pass`.
+- Proxy network is `10.10.0.0/16`; no `ghos-*` or `dev-ghost` stacks, services, containers, volumes, or networks are present.
+- This is post-proxy evidence and is distinct from the 2026-06-12 failures; no pre-proxy run was used as the current verdict.
+
+**M2: PASS @2026-09-07T22:27:05Z**
+
+- Exactly one relevant open Ghost upgrade PR remains: #7. Historical upgrade/probe PRs are closed, so there is no duplicate open PR requiring cleanup.
+- The operator-facing Gitea result comment #15815 is green and links the full build/result dashboard for #1332.
+- Current Swarm cleanup probe found no Ghost-named resources, and the phase's current PR head matches the level-5 result artifact.
+
+**Fresh verdict:** M1 and M2 PASS. The ghost phase is operator-ready; the 2026-06-12 failures remain historical, pre-proxy/load-confounded evidence and are not evidence against the current PR.

+
+### Adversary verification inputs
+
+**WHAT:** M1 is in progress. The correct live PR is `recipe-maintainers/ghost#7`, not historical PR#4. Build #1332 is the fresh post-proxy retry for its current head.
+
+**HOW:**
+
+```sh
+set -a; . /srv/cc-ci/cc-ci-plan/load-env.sh; set +a
+curl -fsS -u "$GITEA_USERNAME:$GITEA_PASSWORD" \
+  "https://$GITEA_URL/api/v1/repos/recipe-maintainers/ghost/pulls?state=open" \
+  | jq -r '.[] | [.number, .state, .head.sha, .head.ref] | @tsv'
+ssh cc-ci 'docker network inspect proxy --format "{{range .IPAM.Config}}{{.Subnet}}{{end}}"; docker stack ls --format "{{.Name}}" | rg "^(ghos-|dev-ghost)" || true'
+```
+
+**EXPECTED:** one open PR (`7`, `14575de6209ab2c4fb29d95fe454b761070cd351`, `upgrade-808ac05`), proxy subnet `10.10.0.0/16`, and no Ghost stack output. Build #1332 reports `success`, level `5`, and all lifecycle results `pass`.
+
+**WHERE:** Gitea issue comment `15814`; Drone URL `https://drone.ci.commoninternet.net/recipe-maintainers/cc-ci/1332`.
