The answer's input is now the object the node-engine seat's contract names, so a decoder without UseNumber turns its
numbers into float64 and a checker re-encoding it for the composer would hand on different digits.

The seat is defined whole in mesh-contracts (ADR 0613 §3), so mesh-sdk takes its names from there (ADR 0613 §5):
EngineSeat and EngineEvents are nodeengine's, EngineComposeCandidateVerb is nodeengine.VerbComposeCandidate, and
ComposeCandidateAsk, ComposeCandidateAnswer and ModuleComposed are aliases of nodeengine's ComposeCandidateInput,
ComposeCandidateAnswer and Module. The encode and decode checks stay here over those types until the seat has a client
package (ADR 0625 §4). For importers: a module's fingerprint is Fp, and the answer's Input is a JSON object
(map[string]any), not raw bytes. compose-candidate's input is the boolean the engine and the checker read; the seat
set's test takes that correction, and the whole seat's added verbs as da653ce reads them. EngineSeat leaves
testdata/seat-names.txt.
