All 18 tests now fail if the module doesn't install what it claims:
- Wayland compositors (hyprland, labwc, niri, sway, mangowc): which &lt;bin&gt;
  + wayland session desktop file present
- openbox: which openbox + xsession desktop file
- hyprlock: which hyprlock + /etc/pam.d/hyprlock configured
- xinit: which xinit + which startx
- xwayland-satellite: which xwayland-satellite + /tmp/.X11-unix created
- wireplumber: which wireplumber + /etc/wireplumber conf fragment
- zzz/seahorse/nvidia-settings: which &lt;bin&gt;
- ifupdown-ng: which ifup + /etc/network/{ifupdown-ng.conf,interfaces}
- resolvconf: which resolvconf + /etc/resolvconf.conf
- regreet: which regreet (via systemPackages) + greetd running at rl3
- plymouth: grep splash /proc/cmdline (initrd-only module)
- gvfs: dbus service file present + GIO_EXTRA_MODULES in pam_env.conf
