The engine's Composed keeps the catalogue's Plan and the declaration types and goes through nodeengineclient's codec; the fingerprint key part is meshcatalogclient's. The candidate answer is nodeengine.CandidateAnswer; the have still holds it through an interim JSON bridge (link.interimAnswers) until the Have group moves.
