That looks like it was a major PITA to figure out how to test, good job.

Logic bug: The function unconditionally overwrites f.passed with the result of f.checkSway(), ignoring previous successful checks from GNOME or KDE. This means if GNOME passes but Sway fails (or vice versa), the final result will only reflect the Sway check. The logic should use OR (||) to preserve any previous successful results: f.passed = f.passed || f.checkSway() or use an early return pattern when a check passes.

Suggested change

	if _, err := lookPath("sway"); err == nil {
	f.passed = f.checkSway()
	if _, err := lookPath("sway"); err == nil {
	f.passed = f.passed || f.checkSway()
