# CRDs and CRD refs

{/* Stub. Source: kix/lib/scope/builders.nix (mkCRD forwards `ownership`), scope.mkCRDRef { installedBy } marks a CRD another package installs so the CRD barrier waits on it (kix/packages/openebs DiskPool is a user), scope.mkCR. Full upstream CRDs with operator-managed fields use ownership.cede (kix/packages/cdi). */}
