A lost event between a shared stream and a module's consumer could not be located: no tool read a consumer's delivered and acknowledged sequence or a stream's messages for one subject. nats_consumer reads from the monitoring document; nats_stream_messages asks STREAM.MSG.GET on the module's own credential, newest first and bounded.
