src/messages builds Response, StateReport, DeferredResponse, ErrorResponse, ChangeReport and the scene, doorbell and simple events from plain values; messageId and times are parameters, so a test compares whole objects. StateBuilder collects properties checked by the descriptors, AlexaError and AlexaErrors carry the payload fields of an error type. AlexaStatusMessage and AlexaErrorResponse move to src/compat and are written on the builders. On the wire, against 1.5.2: a DeferredResponse has no context key, a ChangeReport has no correlationToken, the namespace of an ErrorResponse follows its type, and a ChangeReport without a changed property is not published: send() resolves "" and the bridge reports an error that names the endpoint. 143 tests pass (108 before).
