receiver

Node.js-side inbound pipeline: frames in, opened packets out.

createReceiver(label, receivePacket, logger, open, onDrop?) builds a Receiver from a ReceivePacketFn callback that takes each opened UnencryptedPacket and the session's PacketOpener (protocol.open). receiver.receive(frame) takes the raw bytes from a TCP socket data event, a process.on('message', ...) IPC handler, or a WebSocket message handler; a single open queue opens one frame at a time, which keeps the session's replay counter exact, and delivers each packet in order. A frame that is forged, replayed, malformed, or from another session is reported through onDrop and never delivered.

Hello frames belong to the protocol's acceptHello, not to the receiver. Pair with /node/sender on the other end and a protocol from /node/v3 or /node/v4; a channel from /node/channel creates both for you.

Function signatures match /browser/receiver so cross-runtime communication is symmetric.
