Awesome! Thanks for popping up and clarifying.

For those of us that are not experts, how is this sort of problem generally classified? I've seen others on here say classical planning, but I wasn't sure if that is correct.

I would (also) say that this is a classic planning problem. It's deterministic, observable, static, and discrete.
