Me, too. But now, I looked in the dictionary. I was aware of several meanings of
draft. But none made any sense, in this context (to me). I think, now I
understand. My Webster's shows as 16. (of 32 different meanings) Naut. The depth
to which a vessek is immersed when bearing a given load.

This seems to make sense.

Yes

Perhaps I misunderstand. I'd say no! You want to store the depth, that remains
until qsearch/eval in the HT, not the depth you have done already until this
move. Of course, when you store it, you already have done that remaining depth,
too, because you searched the tree starting from the now current position that
deep.
