+# OpenBao public-listener transition
+
+Status: source implementation complete; live retraction held.
+
+This is the S3-owner procedure for `RMASTER-WP-0020-T09`. It preserves the
+OpenBao Deployment, the `openbao-ui-gateway` Deployment, and its ClusterIP
+Service while removing the public `bao.coulomb.social` Ingress.
+
+## Target access
+
+- Exposure posture: `operator`
+- Named tunnel: `openbao-ui-railiance01`
+- Local UI: `http://127.0.0.1:18200`
+- Cluster target: `openbao/openbao-ui-gateway:8080`
+- Public Ingress: absent after the transition
+
+The tunnel is an ops-bridge local forward to the current ClusterIP and does not
+open a node port. If the Service is recreated with a new ClusterIP, update and
+revalidate the tunnel before use.
+
+Browser OIDC derives its callback from the local origin. Before retraction,
+both the KeyCape `openbao-admin` client and OpenBao
+`auth/netkingdom/role/platform-admin` must allow exactly:
+
+```text
+http://127.0.0.1:18200/ui/vault/auth/netkingdom/oidc/callback
+```
+
+Record only a value-safe attended-login result. Do not record the authorization
+code, token, accessor, callback query, browser storage, or screenshots.
+
+## Guarded sequence
+
+```bash
+make openbao-public-listener-dry-run
+make openbao-public-listener-status
+```
+
+The status command deliberately fails if ops-bridge does not report the named
+tunnel as lifecycle-healthy, even when an orphan forward still answers. Repair
+that state before proceeding.
+
+After KeyCape/OpenBao callback configuration and one attended MFA login through
+the local URL, use the exact hold point:
+
+```bash
+OPENBAO_OPERATOR_LOGIN_VERIFIED=true \
+OPENBAO_PUBLIC_LISTENER_CONFIRM='RETRACT RMASTER-WP-0020-T09 PUBLIC OPENBAO LISTENER' \
+make openbao-public-listener-retract
+```
+
+The command pins the railiance01 cluster UID, rechecks the ClusterIP gateway and
+tunnel, deletes only `openbao/openbao-ui-gateway` Ingress, then proves the
+private path remains healthy and the public name no longer returns a successful
+HTTP status.
+
+## Rollback
+
+During the bounded observation window:
+
+```bash
+OPENBAO_PUBLIC_LISTENER_CONFIRM='ROLLBACK RMASTER-WP-0020-T09 PUBLIC OPENBAO LISTENER' \
+make openbao-public-listener-rollback
+```
+
+Rollback reapplies only the retained Traefik middleware and the explicitly
+named rollback Ingress. It does not mutate OpenBao policy, Raft, PVCs, Secrets,
+or the CoulombCore retention state.

+# RAILIANCE-WP-0027 — OpenBao operator-only access
+
+## Goal
+
+Implement the S3-owner half of RMASTER-WP-0020-T09 without coupling it to
+destructive CoulombCore cleanup.
+
+## T01 — Align the retained compatibility source
+
+```task
+id: RAILIANCE-WP-0027-T01
+status: done
+priority: high
+```
+
+The retained platform manifest now matches the canonical package posture:
+Deployment plus ClusterIP Service only. Ordinary deploy no longer applies the
+public-only middleware. The old Ingress remains solely in an explicitly named
+rollback artifact.
+
+## T02 — Add guarded retraction and rollback
+
+```task
+id: RAILIANCE-WP-0027-T02
+status: done
+priority: high
+```
+
+`scripts/openbao-public-listener-transition.sh` pins the cluster UID, verifies
+source and runtime packet posture, requires a lifecycle-healthy named tunnel,
+and gates live deletion on exact confirmation plus attended-login verification.
+It deletes only the Ingress and provides an exact rollback path.
+
+## T03 — Complete the attended operator cutover
+
+```task
+id: RAILIANCE-WP-0027-T03
+status: wait
+priority: high
+```
+
+Blocked on two facts: KeyCape and the OpenBao role must accept the exact
+loopback callback, and an attended MFA login must pass. The host-namespace
+preflight already proves `openbao-ui-railiance01` lifecycle-healthy and reaches
+the expected overlay. Then execute the guarded retraction, coordinate public
+DNS withdrawal with railiance-infra, and return non-secret acceptance evidence
+to Railiance Master.
+
+This workplan authorizes no OpenBao seal/unseal, policy broadening, PVC or
+Secret mutation, reboot, restore, or RMASTER-WP-0020-T08 cleanup.
