mikkeli a1ed8d8fc5 Boundary v0: WebSocket with heartbeats, acked commands and mock state
One socket on :7700 carries hello, heartbeats both ways (5 s timeout), 5 Hz
state snapshots of envelopes, and idempotent commands. 'mark' is forwarded to
the recorder's control socket. --mock synthesises degrading state flagged as
mock in every envelope; without it a client gets hello and heartbeats only.
Peers outside loopback, RFC 1918 and the tailnet are refused. Deployed on the
car Orin as yukart-gw.service.

# Telemetry gateway
Part of **Project Yukart**, making an old 2008 Mitsubishi Z27AG a bit smarter with modern technologies.
This file serves as the minimalist portal to other docs
## What this repo is about
Runs on the Orin. The network-facing surface for external display clients:
aggregates and rate-limits bus traffic on their behalf, and fronts the navigation
HTTP API so a display has one address to talk to.
It is a bus subscriber. It never touches hardware and never transmits on CAN.
```bash
cargo run -- --mock # on a workstation: mock state, flagged as mock
scripts/deploy.sh # build, glibc check, install yukart-gw on the car Orin
```
