What is a proof worth at my x402 price? One signed number: the premium buyer-agent models gave a cue (a passed certification, an attested sample, pay on delivery, signed receipts, a pledge, the data-not-instructions declaration, or a fake payer count, urgency or an authority claim), in dollars at your price, with its 95% range and whether it's beyond chance, from the newest readable price-of-proof run, and only near the listing prices that run tested.
