+## 2026-06-12 — M2 sweep snapshot: 19 fresh greens, Ghost upgrade regression remains
+
+Bootstrap/access re-checks before the live sweep:
+
+```bash

+```
+
+Open-PR inventory before triggering uncovered recipes showed 16 enrolled repos already had live PRs;
+`custom-html`, `keycloak`, `cryptpad`, and `mumble` did not. I reopened reusable closed PRs for the
+first three (`custom-html#2`, `keycloak#3`, `cryptpad#5`) and created a minimal sweep-only `mumble#1`
+probe PR via the Gitea API.
+
+Fresh post-cfold success set gathered from the live server (`/var/lib/cc-ci-runs/<build>/results.json`):

+Ghost is the lone non-green outlier:
+
+```text
+557  ghost PR#4 @ d88f5801  -> L1 (install pass, upgrade fail, backup/restore/custom pass)
+559  ghost PR#5 @ d42d0f7c  -> L1 (same failure shape on last known-green Ghost head)
+185  ghost PR#4 @ d42d0f7c  -> L4 / pre-lint-era green baseline on 2026-06-05
+```
+
+The critical Ghost comparison is the same ref `d42d0f7c`:
+
+- historical build `185` (2026-06-05): upgrade passed at `d42d0f7c`
+- fresh probe build `559` (2026-06-12): same `d42d0f7c` now fails upgrade with swarm `UpdateStatus='paused'`
+
+That isolates the regression away from cfold itself. In both fresh Ghost failures (`557`, `559`), the
+custom tier still discovered and passed all four `tests/ghost/custom/test_*.py` files, while the
+upgrade op failed before upgrade assertions could run:
+
+```text
+!! upgrade op failed: <ghost-domain>: upgrade redeploy did NOT converge to the head spec — swarm UpdateStatus='paused'.
+The recipe's app service uses update_config failure_action=rollback/pause; the NEW (head) task failed swarm's update monitor,
+so the service reverted/paused and the RUNNING spec is the previous version, not the code under test.
+```
+
+Adversary update pulled during this pass:
+
+- `review(cfold)` commit `93f56ae` added only an idle audit entry to `REVIEW-cfold.md`
+- no finding filed
+- no M2 PASS yet because no `claim(cfold): M2 ...` commit exists
