Channel-centric native communication stack

Superlink

North star / never-ending improvement

Messages, files, calls, screens, and machines through one resilient link.

A Windows C++23 communication prototype joining an always-on daemon, custom reliable UDP transport, optional PSK packet encryption, rendezvous and relay services, WebView2 clients, media capture, transfers, remote control, and headless session helpers.

Chat, code, calls, cameras, files, screens, clipboard, and control in one channel.
Custom network lanes keep voice and control ahead of giant transfers.
Turn a trusted machine into a 24/7 headless node with explicit permissions.

Current truth

A fresh GNU 14.2 build with WebView2 and Opus enabled and PortAudio disabled passes all three registered smoke tests. The default PortAudio-enabled GNU build currently fails inside the dependency under the repository's C23 flags, MSVC configuration rejects the required C23 dialect, and media quality, hostile-network behavior, long-run soak, installer delivery, and the custom PSK/AES-GCM protocol have not been independently admitted.

Every subsystem has a door.

System map

The daemon is the communication authority

surface -> daemon -> peer

Scope

Every interaction belongs to a channel

one scope, many lanes

Local authority

Length-prefixed JSON connects clients to the service

len + JSON over named pipe

Discovery

A small UDP directory introduces live peers

channel presence -> peer address

Custom UDP

ReliableUDP builds ordered work above datagrams

payload -> sequenced datagrams

Scheduling

Realtime traffic is protected from bulk work

voice > control > media > bulk

Packet boundary

Configured channels derive directional AES-GCM keys

channel PSK -> HMAC -> AES-GCM

Client surfaces

Three WebView2 windows share one native bridge

WebView2 <-> JSON bridge

Artifacts

Files travel through a resumable bulk lane

offer -> chunks -> resume -> done

Audio media

Capture, Opus, jitter, mix, and playback meet in the daemon

capture -> Opus -> jitter -> mix

Screen media

Screenshare is subscription-driven and keyframe-aware

viewer -> capture -> JPEG frame

Camera media

Media Foundation feeds multi-camera channel views

camera -> frame lane -> filmstrip

Remote actions

Control and clipboard require explicit policy

request -> policy -> inject

Always-on nodes

A service delegates session work to a helper

service -> session helper -> desktop

Fallback path

The relay forwards addressed channel packets

opaque packet -> peer address

Policy

JSON configuration is the consent surface

config = local consent

Build + packaging

Nine native targets exist; installable delivery does not

source -> native targets, not installer

Evidence boundary

Three smoke lanes prove a narrow executable spine

3 smoke tests != production admission
