atMostOne completion

The "atMostOne" completion is a logical constraint used in problem-solving and programming. It ensures that, among a set of options or variables, no more than one can be true simultaneously. For example, if you have several possible choices, "atMostOne" guarantees that you select zero or one option, but never two or more. This helps model situations where only a single selection is allowed, or none at all, maintaining clear and consistent rules in the problem space.
