Function normalized_repository_ref 

pub fn normalized_repository_ref(
    r: &RepositoryRef,
    owner_namespace: &str,
) -> RepositoryRef

Normalize a RepositoryRef against the namespace it resolves relative to (owner_namespace, the consuming CR’s namespace): a namespaced Repository ref carries its EFFECTIVE namespace explicitly (so a later reader can re-resolve it from anywhere — e.g. after the owning recipe is gone); a cluster-scoped ClusterRepository ref carries none (the webhook forbids one). This is the one normal form every pin uses — status.resolved.repository (the controller’s run-time pin) and Snapshot.spec.repository (the mint-time pin a multi-repo fan-out child or replication copy CR carries) — so repo_key over a normalized ref is namespace-independent. Exhaustive over RepositoryKind.
