FRP DEV Contract

The DEV reverse link is D601 to master edge through frp.

Public DEV endpoint: http://74.48.78.17:6667
hwlab-tunnel-client owns the frp client health contract.
hwlab-edge-proxy owns public HTTP ingress on port 6667.
frps.dev.toml reserves 6667 only as a TCP remotePort; do not also bind it as vhostHTTPPort, because that collides with the DEV TCP proxy.
No secret values are stored in this repository. Operators must provide auth material out of band before a real deployment.
UniDesk backend, provider-gateway, and microservice proxy are not HWLAB runtime substitutes.
