I also had this dr which has htr in 14 but it's not good:

interestingly this is flippable to give a short E slice skeleton:

missed 21 from all four variations of this dr, kill me

most irritating one is i had this skeleton

but you have to insert E2 twice for +1 then S solves in +0

there are so many paths to check after (F B) idk about finding it from the niss path. setting up to the 5-move 4a2 trigger may be more realistic
