Pass the ref's root nanopub (root_np); the query resolves the ref via npa:rootNanopub and its space IRI, gates the authorized signer pubkeys on the ref's admin/maintainer role instantiations, and otherwise mirrors get-view-displays (same columns, latest-version resolution via the supersedes chain, preset-supplied views). Because view displays are not materialised into the spaces repo, this is a federated join: the per-ref admin gate lives in the /repo/spaces service while the displays come from the view-display type repo.
