NEW pkg/zapwire: pure-Go leaf holding the frozen CLOB ZAP frame (Submit=66/Place=65/ Cancel=40/EnsureMarket=32/Ack=24, FillWireSize=17, float64 codec) so the public precompile imports the wire format without the cgo/GPU engine. SubmitMarketable (IOC taker): removed time.Now()+atomic.AddUint64 from the consensus path; trade ts derives from block-derived order ts; fills carry maker+taker identity. zap_server.go docstring demoted authority-> gateway. nocgo: verifyOrdersCPU returns nil for empty. Verified pkg/zapwire 6/6, full ./... green.
