Pairs ranked — gap × what WE can move
profit/h = spread% × the slower leg of OUR achievable VES/h — measured seat throughput (72h) first, capture-scaled market flow for unseated tiers, capped by flip-cycle turnover. "•edge" = live book spread adjusted by our measured fill edges vs the concurrent book (24h), exactly what the engine scores on. "Mkt ceil" is the old market-wide upper bound. NOTE: the engine can only seat tiers inside its configured bands — a top pair with an out-of-band leg is shown, not seatable.
