Module restream_session 

Node end of a live restreamer session (A2 / A3).

The node dials C2’s uplink, OPENs a channel, then runs the inner Noise_NK handshake toward the relayed recipient key as ordinary DATA frames: msg1 goes up through C2 into the core drain, msg2 comes back down the same stream. After that every request and reply is Noise transport ciphertext, wrapped in C2’s outer layer on the way up. C2 only ever sees opaque bytes, and the node never learns what sits behind C2.

One TCP carries every channel (C2 routes downlink by node id). A single FIFO send queue would let browser frames or a stuck mail channel wedge PTY control (head-of-line blocking). Outbound traffic is therefore queued per-channel with priority scheduling, browser frames are coalesced under pressure, and a write timeout tears the socket down so the bridge reconnects.

Structs

NodeSession

NodeUplink

One TCP uplink to C2 carrying any number of channels.

UpstreamKeys

Keys C2 hands a node at enrollment: its own outer key and the upstream recipient key.

Enums

SendPrio

Outbound priority on the shared uplink. Lower ordinal = sent first.
