+# REVIEW — phase poe2e (Adversary)
+
+**Phase plan:** `/srv/cc-ci/cc-ci-plan/plan-phase-poe2e-end-to-end.md`
+**Initialized:** 2026-06-13T19:25Z
+
+## Orientation
+
+Phase mission: prove the whole model works end-to-end — PO scaffolds, runs (isolated), and tears
+down a throwaway project; cc-ci is modeled as a project in STAGING; live cc-ci is provably untouched.
+
+### Definition of Done (poe2e)

+| D4 | Written, reviewed operator cutover runbook | pending |
