# NK-WP-0032 — OpenBao operator loopback callback

## Goal

Admit the exact callback derived by the ClusterIP-only OpenBao UI gateway when
operators reach it through the named `openbao-ui-railiance01` tunnel, without
weakening MFA or broadening the OpenBao policy.

## T01 — Update and validate the code-defined callback contract

```task
id: NK-WP-0032-T01
status: done
priority: high
state_hub_task_id: "f231077e-7440-5f20-9045-afab90fa8286"
```

Add `http://127.0.0.1:18200/ui/vault/auth/netkingdom/oidc/callback` to the
KeyCape `openbao-admin` public-PKCE client, the OpenBao `platform-admin` role
template, bootstrap validation, live authorization verifier, and operator
documentation. Preserve the former public callbacks only for the bounded
listener rollback window.

Completed 2026-08-23. Three focused regression tests, Python compilation, Bash
syntax validation, and `git diff --check` pass.

## T02 — Apply and prove the live KeyCape client addition

```task
id: NK-WP-0032-T02
status: done
priority: high
state_hub_task_id: "360bc410-d7ed-53b6-b5fc-2ce8b37b653f"
```

Patch only the code-defined non-secret client configuration, restart KeyCape,
and prove both the live Secret contract and public authorize endpoint accept
the exact loopback URI. Do not record the Secret contents or an authorization
code.

Completed 2026-08-23 on Railiance01. `sso/keycape-config` was patched without
printing decoded data, `deployment/keycape` rolled out successfully, and the
value-safe verifier proved the live client contract, exact loopback redirect,
legacy rollback redirects, and OIDC discovery endpoint. No authorization code
or Secret value was observed.

## T03 — Apply and prove the live OpenBao role addition

```task
id: NK-WP-0032-T03
status: done
priority: high
state_hub_task_id: "73b77110-2d4f-527e-98eb-2ec33897681e"
```

An attended platform-admin/root-sudo authority must apply the updated role
template to `auth/netkingdom/role/platform-admin`. Record only that the exact
URI is admitted. Do not record a token, accessor, authorization code, callback
query, browser storage, or role response body.

## T04 — Return attended-login evidence to Railiance Platform

```task
id: NK-WP-0032-T04
status: done
priority: high
state_hub_task_id: "f62bda4a-7607-5c50-9e04-664cc1b829ac"
```

After T02 and T03 pass, perform one attended MFA login through
`http://127.0.0.1:18200` and return only the success/failure outcome. This task
does not authorize public Ingress retraction; Railiance Platform retains that
separate guarded hold point.

## Infrastructure review — 2026-09-28

T03 and T04 are complete from existing owner evidence; no new attended login
or role write is needed for this reconciliation. Railiance Platform
`docs/evidence/2026-09-15-openbao-loopback-callback-already-present.json`
proves the exact callback already present, Warden exit 0 and session revocation.
`docs/evidence/2026-09-15-openbao-public-listener-retract.json` records successful
operator loopback MFA, private HTTP 200, gateway readiness and public Ingress
retraction. `RPF-WP-0025` closure on September 22 records the handoff to
Railiance Master. These receipts discharge the original role and login gates.

Today the gateway and OpenBao are ready, their Services are ClusterIP, and the
openbao namespace has no Ingress. The September 24 callback-prune receipt
retired the public callbacks; current NetKingdom client source also forbids
their return. T01's bounded rollback requirement is historical, not an
instruction to restore public callbacks. DNS withdrawal remains the
railiance-infra owner residual described by RPF-WP-0025; this review does not
claim it is complete or authorize a listener change.
