Pass the ref's root nanopub (root_np); the query resolves the ref via npa:rootNanopub and returns, for each trust-state-validated admin RoleInstantiation (npa:inverseProperty gen:hasAdmin) scoped to that ref (npa:forSpaceRef), the admin agent and each of its AccountState pubkey hashes. Ref-scoped variant of get-space-admin-pubkey-hashes (which is IRI-keyed via npa:forSpace and merges all refs of an IRI).";
