 "notes": "EPISODE 8 (2026-11-10, about 01:05Z). State before: 79 of 150 items used; this is the last planned episode (maxEpisodes 8). NOTHING LANDED since episode 7: this episode was woken by requester note 7 (01:00Z) about ten minutes after episode 7's decisions were accepted, and all 15 of episode 7's items were still queued (r6-confirm-qm-a qa1-qa4, r6-confirm-qm-b qb1-qb4, r6-qm-trim qtr1-qtr2, r6-rerun-blocks tb3r/pb1r, r6-arb ar1-ar3), plus r5-qm-t2 qt1/qt2, r4-qm-port qm-1, r4-confirm-p2-a pa1, r4-confirm-p2-b pb3 and r3-gate-q (3) still running. DECISION: finish=false, because the goal's answer (the qm policy's 2,048-seed score and a gas-fit qm contract) is exactly what the queued items produce; finishing now would write up without them. Spawned r7-qm-trim (qtr3, qtr4), copies 3-4 of the qm-2 gas trim the requester asked for in note 7 (3 copies, engine peak <= 240,000, fees unchanged, cheaper spline evaluation, shared ask/bid basis, trim-1's math trims; truncation only as a declared last resort), engine seeds 9539000..9539127 and 9540000..9540127 vs trim-1 and t03. Wake on the five r6/r7 batches or after 300 minutes. If the plane allows no episode 9, the write-up is made from these notes and the reads listed (25 results). Budget after this episode: 69 items.\nWRITE-UP PLAN (whoever writes it). Submission rule (note 7): >= +0.3 over trim-1 on 2,048 fresh engine seeds, afterSwap peak <= 245,000, 0 OOG, complete code + sha256. (1) Pool qm-2's eight blocks qa1-qa4 (9613312..9614335) and qb1-qb4 (9614336..9615359): qm-2 minus trim-1 directly (mean of all 2,048 diffs, se = sd/sqrt(n)), also minus t03 and IB; gas verdict = max per-chunk peak over all blocks and total OOG. Expected about +0.8 over trim-1 (128 seeds: +2.137 se 0.113 vs t03, 124/128 wins). (2) From r6-qm-trim qtr1/qtr2, r7-qm-trim qtr3/qtr4, r5-qm-t2 qt1/qt2 and qm-1: a contract with runtime <= 24,576 B, engine peak <= 245,000 (ideally <= 240,000), 0 OOG, gate F passed. A trim whose fees are BIT-IDENTICAL to qm-2 (0 differing callbacks, equal trace digests) inherits qm-2's 2,048-seed confirmation (the engine is deterministic given the fees): name it the submission with its code URL and sha256 and say why the score transfers. A contract only within 0.01 bps (qt1/qt2, or a declared last-resort trim) gets qm-2's pooled score as the policy's score plus its own 128-seed run as direct evidence, saying plainly which seeds ran on which contract. If no gas-fit qm contract lands, the submission stays trim-1 (on the board at 524.1189) and qm-2 is reported as beating it by the pooled margin at peak 245,140 with 0 OOG in 1.4M calls, for the requester to judge (net-1 at 245,377 also ran with 0 OOG, so the engine's real limit is above the printed cap; the requester's rule is the number).
