The Amount line gave only the first swap step's amount. It now gives the total the steps take of Token In: the amount of the step that sets the input side plus each later take of it by a step the user pays. A V4 step, the first included, takes what its SETTLEs paid by the user state. A take of another token, one after an amount that is not a quantity, or one of unknown amount gets lines of its own. A step that may take what the decoder did not read gets one line saying so and leaves no figure. A PERMIT2_PERMIT names Token In; its amount stands only in the plain shape of Uniswap's own routes. Also closes #628. Model: opus-5-5
