name: SSH Windows hosts

# Design D5/D6 exit gate, Windows half: the real client-side relay deploy against a real
# Win32-OpenSSH server on 127.0.0.1 (inbox capability and the pinned 10.0.0.0p2-Preview release),
# on x64 and arm64. Each job provisions a private sshd service and one standard account per cell
# (config/ci/windows-ssh-provider/), hides the host toolchain from SSH sessions behind logging
# shims, and asserts rung A on the pinned node.exe in both DefaultShell cases plus the opt-out.
