This directory owns the Docker Compose stack for the Windows native E2E lane. It runs on the current Linux controller and owns the Linux RVBox server, nginx TLS proxy with a per-run matching-host self-signed leaf, SQLite/segment state, control socket, and logs. The v1 client deliberately accepts this self-signed leaf when no CA file is configured; it is encrypted transport, not server authentication.

The Helium VM never hosts this stack. It receives only rvbox.exe and client TOML through the Windows fixture controller.
