Very simple elegant solution.

An even more elegant solution - construct each of the two or more holes so that only the part meant to fill that hole fits. There could never be an error in that universe of holes.
You're right! I can't think of anything else on this planet that has two holes, in close proximity, with very different purposes. Oh, wait.....
Not always such different purposes. But surely we humans can do better than evolution when it comes to distinguishing the purposes of holes.
