Module remote_gateway 

The proxy’s view of the remote tunnel.

gglib-app-services owns the tunnel (ADR 0012) and gglib-proxy cannot depend on it — the dependency runs the other way. What the proxy needs from the tunnel is small and fits a port: say whether /mcp may be reached from outside, and be told that a request arrived through the tunnel at all. Pairing is not part of it: the tunnel edge answers a pairing request itself and never forwards it. Everything else about the tunnel stays where it lives.

Design Rules

• No iroh or modelpipe types: the proxy learns what it is told and never what the transport is.
• Synchronous. Every implementation is a lock and a counter, and a port that forces an await on the request path for that would be paying for nothing.
• Debug is a supertrait because the config that carries this derives it.
