+Move the authoritative OpenBao runtime from CoulombCore onto

+ADR-0008 later split admission from exposure. The 2026-08-15 snapshot
+lists that name as a **routed close, not a grant**. Target inventory is
+`public_ingress: false`. Consumers already use
+`openbao.openbao.svc:8200`.
+
+Route to `rapp-openbao` / `railiance-platform`: drop public Ingress,
+keep ClusterIP, set `exposure.posture: operator` with a named
+ops-bridge tunnel for the UI. Do not implement NetworkPolicy here.
+
+**Done when:** `bao.coulomb.social` is not a public listener we publish,
+the runbook no longer treats public DNS as the steady state, and the
+declaration carries `operator` (or `private`) rather than an implicit
+public grant.

 ## Safety constraints
 
 - Never initialize or overwrite either OpenBao instance without verified
