Turning on a WireGuard profile whose server was unreachable used to cost the
whole network stack, and the only way out was nmcli typed into a terminal.
Quickshell's Networking module has no VPN surface, so this arrives as the one
sanctioned nmcli exception: a helper that lists, raises and lowers profiles,
a service that watches NetworkManager for changes made anywhere, a quick
settings tile (left-click toggles the most recently used profile, right-click
picks among them), and a bar glyph while a tunnel is up.
The safety property is in the helper, where it cannot be skipped: activation
waits a bounded 25 seconds, and a failure is rolled back down and reported
instead of leaving a black-hole default route. The contract pins exactly that,
against a stateful stub NetworkManager.
