This is not an NxM verifier hell. I explicitly talked about one way which is parallel generation + classifier. You can also use majority voting here. Both would give you the right answer at each step without having to write code or test cases, just a simple prompt. There are more ways to do the same, eg: verifier blocks, layering, backtracking search (end to end assertions and then see which step went wrong), simple generative verifiers with simpler prompts and so on.

For non software world, people use majority voting most of the time.
