    dct:description "Resolves which version a reference to a space-governed definition should use: a resource view, an assertion/provenance/pubinfo template, or any other definition whose versions follow the embeds/isVersionOf/governedBy convention (docs/views-and-presets-as-maintained-resources.md and docs/template-identity-and-governance.md in the nanodash repo). Takes the definition's kind (its dct:isVersionOf target; kind), the space named by the pinned version's gen:governedBy (space), and the nanopublication URI of the pinned version (pin). If the kind is registered as a maintained resource of the space (npa:isMaintainedBy in the current space state), the result is the newest version of the (kind, space) pair: a nanopublication that npx:embeds the version, which declares dct:isVersionOf <kind> and gen:governedBy <space>, is signed by a current member+ (admin/maintainer/member, not observer) of the space's governing ref, and is not invalidated by its own key (mode 'governed'). Without such a version the result is empty and the caller keeps its pin, which is not re-validated here. If the kind is not registered for the space, gen:governedBy has no effect and the pin resolves like an ungoverned version (mode 'supersedes'): the single current head of its npx:supersedes chain, signed with the pin's own key and not invalidated by it. This is the same rule as get-latest-version-of-np, so a chain that has forked into several heads yields no row. Returns at most one row: version (the embedded definition IRI, or the nanopublication URI if it embeds none), date, np and mode. Hosted on the spaces repo; the version lookups federate to the full repo with kind, space and pin as text-substituted constants. Supersedes the two-parameter version, which returned nothing for an unregistered kind and so kept every reference to such a version on exactly that version, ignoring even same-key supersedes.";
