List space members
type: grlc-query
description: Lists the members (admin, maintainer, or member tier) of a given space together with their highest tier and links to the role-assignment nanopubs (labelled by the role name). Observer-tier roles are excluded. Reads the materialized tier directly off each validated gen:RoleInstantiation (npa:hasRoleType) and its role (gen:hasRole) in the current space state; no role-declaration re-derivation. IRI-keyed by npa:forSpace (param space).
