    dct:description "Lists the observers of a given space ref (space IRI + root definition): agents holding an observer-tier role and no validated admin/maintainer/member role. Pass the ref's root nanopub (root_np). Per (member, role) only the latest role-instantiation nanopub is returned (by dct:created), so a role re-asserted several times shows once. Unlike list-space-observers (validated-only), this also includes self-declared observers whose key is not trust-validated (no accepted introduction), flagging them in the headerless ?unverified_noheader column. The role label is pinned to the role the space actually assigned (RoleAssignment), correct even when several declarations share a property. Ref-scoped; shows un-introduced observers rather than hiding them.";
