Type Alias: LtpEvent
LtpEvent = {
type:"enq"; } | {type:"ack"; } | {type:"nak"; } | {type:"eot"; } | {frame:AstmFrame;type:"frame"; }
An inbound protocol event the consumer feeds the reducer: one of the four LTP
control signals (ENQ/ACK/NAK/EOT) read off the wire, or a frame the
consumer already decoded with decodeAstmFrames (the reducer reuses the codec's
trusted/checksum verdict - it never re-derives it).
