Thanks. Are you sure this is the correct vowel harmony here?
I don't understand your argument here. The "helper vowel" can be inscribed using one of the ordinary vowel marks. (I'm pretty sure the grammarians address this explicitly.) Scribes may choose not to do this, but they can if they want to. This occurs in many cases, e.g. after the question particle hal.
I would like to see how you can add a vowel to a tanween mark.
