+    Sets up OTE (non-payload extension binary) discovery for the Windows Machine
+    Config Operator. Creates an ImageStream pointing to the WMCO CI image (which
+    contains wmco-tests-ext.gz at /usr/bin/wmco-tests-ext.gz), annotates it with
+    testextension.redhat.io annotations for OTE discovery, installs the
+    TestExtensionAdmission CRD, and creates an admission CR permitting the WMCO
+    namespace.
+
+    This step must run after WMCO is deployed and before openshift-tests runs.
+    It implements the non-payload OTE binary mechanism from openshift/origin#30863.
