    dct:description "Returns the latest non-invalidated SpaceDefinition per space ref from the server-materialised spaces repo, joined to the declaring nanopublication for its label and type. Ref-aware variant of Get spaces (v2): adds the space ref (?ref) and its root nanopublication (?root) so the client can key one space per ref (space IRI + root definition) rather than per IRI. v4 (supersedes the v3 RAD5KmWO…): the invalidation filter is gated on a shared signing pubkey (npa:hasValidSignatureForPublicKeyHash) between the invalidating nanopub and the space-definition nanopub, so a foreign-key retraction can no longer suppress a space definition (issue #487).";
