    dct:description "Ref-scoped variant of get-view-displays (the Content-tab renderer query) for a single space ref. Takes TWO inputs: the space IRI (resource) and the ref's root nanopub (root_np); the authority gate is scoped to admins/maintainers of THAT ref (npa:forSpaceRef resolved from root_np) instead of the space IRI merged across all its refs. Both inputs are concrete (VALUES) so federation bindings propagate. Space-only companion to get-view-displays; same columns. Regenerate from the latest get-view-displays by adding the root_np VALUES, the ?passedRef npa:rootNanopub resolution, and npa:forSpaceRef ?passedRef on the gate's RoleInstantiation.";
