Request sitting-requester OpenBao custody without allocating a CCR.

Verifier + attended reader on a new informed-decision KV path, not a
widening of CCR-2026-0024/0025. Intents still match approval-engine
canonical binding. No secret, no apply, no bind.

+# Sitting requester custody — requested, not allocated
+
+**Workplan:** `INFD-WP-0002-T03`
+**Owner:** `railiance-platform` (OpenBao KV + ESO + attended reader)
+**Peer:** `key-cape` (client row; not yet registered)
+**Status:** requested 2026-09-14. **No CCR id is allocated here. No secret
+is in this repository. Do not apply from this file.**
+
+Same split as `CCR-2026-0024` / `CCR-2026-0025` for
+`secrets-engine-requester`: one KeyCape **verifier** path (ESO) and one
+**attended operator reader**. Do not widen those CCRs or that KV path.
+
+## What to allocate
+
+Platform assigns the next CCR pair. Suggested shape, names only:
+
+| Piece | Suggested value |
+| --- | --- |
+| KV path | `platform/workloads/informed-decision/sitting-requester` |
+| Field | `CLIENT_SECRET` only |
+| Verifier policy | read that path; Kubernetes auth for `external-secrets` in `external-secrets` |
+| Reader policy | read that path; OIDC attended operator; sibling paths and parent listing denied |
+| ESO / env | `KEYCAPE_INFORMED_DECISION_SITTING_REQUESTER_CLIENT_SECRET` (already the `secretRef` name in the KeyCape request) |
+| Workload | `informed-decision` |
+| Tenant | `platform` / `tenant:platform` |
+
+Do not put `approval:approve` or `approval:consume` material on this path.
+The human PKCE client stays public and secretless.
+
+## Activation conditions (when platform and key-cape accept)
+
+1. KeyCape owns `informed-decision-sitting-requester` (`applied: false` today).
+2. Attended authority writes CAS=0 custody to the new path only.
+3. Exact policy/auth readback; sibling `secrets-engine/approval-requester` denied.
+4. Excess scopes (`approval:approve`, `approval:consume`, `approval:read`) refused at token exchange.
+5. Wrong secret refused. No human entry synthesized. No POST of sitting intents until that proof exists.
+
+Registration contract: `docs/keycape-sitting-requester-registration.md`.
+Create intents (not posted): `docs/batches/2026-09-14/approval-create-intents.json`.
