+# T03 requester session
+
+CCR-2026-0025 admits only the new requester path. The contained Warden login
+uses `secrets-engine-requester-workload-kv-read`. Its owner command checks exact
+reader policies and denial of the existing consumer path, obtains one in-memory
+create-only token and submits only the three frozen T03 records. It cannot bind
+or consume an approval and never reads the KeyCape verifier Secret.
+
+Use the current source catalog explicitly while the installed bundle is older:
+`WARDEN_ROUTING_CATALOG=/home/worsch/ops-warden/registry/routing/catalog.yaml`.
+
+The reviewed child is
+`/home/worsch/informed-decision/.venv/bin/python -B /home/worsch/railiance-platform/scripts/create-t03-approval-requests.py`.
+It requires the owner-bound Approval Engine tunnel at 127.0.0.1:18281 and frozen
+native evaluator receipts. Its output is metadata-only persisted by the owner;
+Warden self-revokes and removes the reader helper after the child exits.
