+# NetKingdom credential custody contract
+
+Status: **draft / blocked pending OpenBao owner confirmation**
+Incident: `KEYCAPE-EXPOSURE-20260823-01`
+Consumer procedure: NetKingdom `NK-WP-0033`, resolver reconciliation revision
+`eec7007` / checkout `f2e578c`
+
+This document defines the Railiance-side contract without containing or
+deriving any credential value. It is not an authorization to fetch, export,
+apply, or rotate a secret.
+
+## Ownership
+
+- `railiance-platform` owns OpenBao custody, policy, delivery, rotation
+  metadata, and revocation evidence.
+- `net-kingdom` owns the privacyIDEA resolver contract and attended consumer
+  reconciliation.
+- `ops-warden` routes the lane only; it does not fetch or proxy either value.
+
+## Required OpenBao metadata (owner must fill, never guess)
+
+| Lane | Canonical path | Field | Delivery | Status |
+| --- | --- | --- | --- | --- |
+| `net-kingdom-lldap-bind-credential` | `REQUIRED_FROM_OPENBAO_OWNER` | `REQUIRED_FROM_OPENBAO_OWNER` | protected attended input to NetKingdom resolver helper | blocked |
+| `net-kingdom-privacyidea-admin-token` | `REQUIRED_FROM_OPENBAO_OWNER` | `REQUIRED_FROM_OPENBAO_OWNER` | protected attended input to provider-admin helper | blocked |
+
+The owner receipt must also identify the KV mount/version semantics, the
+least-privilege read/update policy, the authentication method, the expiry or
+rotation behavior, and the approved attended handoff. No value belongs in this
+file, State Hub, Git, chat, argv, or ordinary logs.
+
+## Consumer handoff
+
+Once the OpenBao owner supplies the metadata above, Railiance-platform records
+the receipt identifier and passes only protected input to the pinned
+NetKingdom procedure. The resolver repair must use the minimal two-input
+`--reconcile` flow; audit proofs (lookup, MFA, predecessor denial) remain a
+separate read-only operation.
+
+## Current gate
+
+The routing lane is registered but remains `resolvable: false`. No
+`warden access --fetch`, proxy execution, resolver retry, or predecessor
+restoration is authorized until the OpenBao owner publishes the missing
+metadata and the attended handoff is approved.
