Haram and makruh tahrimi both involve serious restrictions, but their technical standing and the strength of supporting evidence differ in the textbook's Hanafi scheme. Makruh tanzihi is another category and must not be flattened into the others.
Similarly, rukhsah is a concession tied to a qualifying excuse, not unrestricted permission. The original rule, or azimah, and the specific conditions of the concession must be kept distinct.
