Part2 is quite often what you wish for in 2), isn't it? At least for the later puzzles, part1 is often something that can be solved naively, while part2 needs some cleverness to not blow up.
Yeah, usually part 2 is. Bear in mind that tonight's puzzle is a warmup, it's day 1 after all!
I do find there's usually one or two spots that you can eek by with threads and throwing compute power at the problem. But those are rare — usually you have to actually solve it.
