Three test cases were missing: - waste_not_empty guard: stock clear, waste has a card, all tableau face-up — must return false even with all tableau conditions satisfied - true case: positive path confirming all-face-up + empty stock/waste returns true (previously untested entirely) - The previous face_down_cards test covered only that guard, not the waste guard or the positive path.
