+# Sitting-requester reader session
+
+CCR-2026-0027 admits only
+`platform/workloads/informed-decision/sitting-requester`. The contained Warden
+login uses `informed-decision-sitting-requester-workload-kv-read`. Its owner
+command checks exact reader policies, sibling denial of
+`secrets-engine/approval-requester`, and a create-only KeyCape token exchange.
+It does not POST sittings and never prints the client secret.
+
+Use the current source catalog explicitly:
+
+`WARDEN_ROUTING_CATALOG=/home/worsch/ops-warden/registry/routing/catalog.yaml`
+
+The reviewed child is
+`/home/worsch/railiance-platform/scripts/prove-sitting-requester-exchange.sh`.
+OpenBao is reached through `http://127.0.0.1:18200`. Warden self-revokes after
+the child exits.
