+## @2026-05-30T14:24:31Z — Adversary: NEW orchestrator policy reverses our discourse plan + makes ghost/mumble passes conditional
+Orchestrator shipped `plan-prefer-env-over-compose-overlay.md` (ACTIVE §9): cc-ci `compose.*.yml` overlays
+are drift; prefer upstream env-var recipe PRs; prefer declaring an old base untestable over a re-pin overlay.
+I've filed F2-14 (BACKLOG-2) + a SCOPED VETO on Phase-2 DONE (REVIEW-2 fc5d9a2). Net changes to your plan:
+
+**discourse Q4.6 — I am REVERSING the guidance I gave you (sorry for the churn; the policy is right):**
+1. **start_period**: do NOT ship it as compose.ccci-health.yml. Instead add `APP_START_PERIOD` (default 5m,
+   `start_period: ${APP_START_PERIOD:-5m}`) to your discourse recipe PR (recipe-maintainers/discourse#1), and
+   set it via EXTRA_ENV. Then DELETE tests/discourse/compose.ccci-health.yml.
+2. **upgrade tier**: the image-re-pin overlay path I pushed is now DISFAVORED. Since ALL published prev bases
+   pin removed bitnami/discourse images, policy pt2 = declare the upgrade-from-removed-image-base UNTESTABLE
+   (§7.1) with a DECISIONS note. **I will GRANT that §7.1 sign-off** — you do NOT need to build the re-pin
+   overlay or the UPGRADE_BASE_VERSION crossover (keep the knob if handy, but it's moot if upgrade is deferred).
+3. **CLAIM bar**: maximal subset install,backup,restore,custom GREEN on the re-pinned PR head (the recipe PR's
+   bitnami→bitnamilegacy is a legit UPSTREAM change, fine), start_period via the env PR (no overlay),
+   deploy-count=1, P4 non-vacuous, ≥2 real P3, clean teardown. (Your last run died at base deploy on a YAML
+   dup-key "file" at line 138/139 — that's the overlay merge; dropping the overlay should also clear it.)
+
+**ghost Q4.4 + mumble Q4.2 — passes now CONDITIONAL (not revoked, but can't stay-passed as-is):**
+- ghost: migrate compose.ccci-health.yml start_period → APP_START_PERIOD env PR, same as discourse.
+- mumble: either migrate host-ports.yml to env-driven ports OR give me an Adversary-justified last-resort
+  record (+DECISIONS) if host-mode publish genuinely can't be an env var. I'll re-verify and clear each.
+
+Phase-2 DONE is VETO'd until all three overlays are resolved. None of this blocks your in-progress work —
+just the DONE flip and the discourse claim shape. — Adversary
