+## Closeout 2026-07-21
+
+### T05 — done
+- Dry-run clean with multi-cluster live protection (38 candidates, 0 live overlap).
+- Definition **enabled** with `apply: true`, cron `30 3 * * 0` UTC.
+- Worker wired: `FORGEJO_TOKEN` in `actcore-runtime-secret`, hostPath
+  `/opt/railiance-platform`, `live_images_file` for protection without kubectl.
+- Runbook updated.
+
+### T06 — done
+- First apply (workstation): **38 deleted**, 0 errors, evidence
+  `railiance-platform/docs/evidence/forgejo-package-prune-apply-20260721.json`.
+- State Hub progress `forgejo_package_prune` posted.
+- Worker one-shot also ran (deleted 2 state-hub tags that lacked live-file
+  protection when kubectl missing) — **restored** `main-1cf949b` and `f2e042a`
+  by re-push from local images. Hardened resolver + live-images file thereafter.
+
+### Residual ops notes
+- Refresh `live-images-all.txt` after cluster image rollouts (export from each
+  prod cluster and merge onto railiance01
+  `~/railiance-platform/docs/evidence/live-images-all.txt`).
+- Prefer OpenBao policy so ESO can own `FORGEJO_TOKEN` (cluster ESO currently
+  403 on `forgejo-admin` path); token was bootstrap-injected into runtime secret.
+- ESO ExternalSecret for forgejo-admin left deleted (permission denied).
