# Grants the operator delegated-auth permissions (TokenReview + SubjectAccessReview)
# required by controller-runtime's WithAuthenticationAndAuthorization metrics filter.
# These are cluster-scoped resources and cannot be granted via a namespace-scoped Role,

# only renders a namespace-scoped Role. In cluster-wide mode the manager ClusterRole
