A V4 step's input side is the currency SETTLE or SETTLE_ALL names, else the one currency some swap action spends and none buys; its output side is the currency TAKE or TAKE_ALL names, else the one some swap action buys and none spends. Amount and Min. received come from those actions, summed when several exact-in actions each state one. A step with an unread swap action is named only by SETTLE, SETTLE_ALL, TAKE and TAKE_ALL, and shows no figure. A side a step with a swap action leaves unknown shows no other step's token or figure. Before, the first swap action set both sides, SETTLE_ALL and TAKE_ALL went unread, and a SWAP_EXACT_OUT was read as spending its path's last currency. Model: opus-5-5
