 "notes": "EPISODE 9 (2026-11-07). STATE: round 4 (31 items, r4-d1/d2/d3/f1/f2/s1/m1, NP deltas vs NP on 800000..801999) has NOT STARTED: all waiting, none running; r4-trunk (code, best/** = NP) waiting. Round 3: 18 still running (r3-d1 x3, r3-d2 x4, r3-d3 x4, r3-f1/post-arb-pair, r3-f2/th-pia, r3-m1 ch-replicate/ch-calib/ch-repo-scan). Handed 2: r3-m1/pub-scan, r3-d2/tune-tox (below). Nothing measured vs NP yet: NO PROMOTION 4, round 4 unscored (round 3 promoted: stop rule untouched). BEST = NP. Ep9's first attempt was rejected invalid_output (brief over 3000 chars, notes over 8000); this one spawns ONE batch of 4 items (vars key+task, brief ~2950 filled).\n\nDECIDED (4 items, 124 of 600 used): r5-pri = the requester's 04:55Z priority, scheduled nowhere else at 4000 seeds: NP2 = CH + edit A (norm-phat) + edit B (two-print re-specified exactly: slot 11 = previous print's direction in the step; later-print alpha 0.12 when the direction repeats, else 0.06), both edits pasted verbatim. combo-fresh-a/b: NP2 vs NP and vs CH on 1000000..1001999 and 1002000..1003999 (ep9 fresh block; pool to n 4000 only if both code_sha256 agree: mean of means, se = sqrt(se_a^2+se_b^2)/2). combo-calib-a/b: NP2 on 900000..904999 and 905000..909999 (pool: mean = (sum_a+sum_b)/10000, se from pooled sumsq). Each item also scores NP on 0..999 (must be 526.0337302497852) and NP2 on 0..999. r4-d2/np-two (original two-print code 6f23c204, 800000..801999) is an independent estimate. Wake: r5-pri and r4-m1 settle, or 600 min. Read = 30: r5-pri x4, r4-m1 x3, r3-m1 x3, r4-d2 x5, r4-d1 x5, r4-d3 x4, r4-f1 x4, r4-f2 th-killed + edge-base.\n\nSCOREBOARD (paired, n 2000 unless said; runs are bit-reproducible across machines):\n- BEST, promotion 3 (ep8): NP = CH + 9 lines inserted right before `uint256 tradeRatio = ...`: `if(!firstInStep&&feeUsed>30*BPS&&gamma>0){uint256 nS=trade.isBuy?wdiv(wmul(spot,gamma),WAD-30*BPS):wdiv(wmul(spot,WAD-30*BPS),gamma);pHat=wmul(pHat,9*WAD/10)+wmul(nS,WAD/10);}` (a later-in-step print reveals the 30 bps pool's spot through the router's equal marginal prices; blend 0.1 into pHat). sha256 f1ea5b95c853ef28399a0b22ec222773525dba18c92282c04993170c97b57c83 (r3-f1/norm-phat). vs CH on 600000..601999: +0.4645 se 0.0159 (worst -4.58 seed 601271). 0..999 = 526.0337302497852 (se 2.79).

New write-up: Algebra Finance, LinkedIn pulse \"amm-fee-challenge-notes-from-our-run-optimization-arena-qe3ff\" (2026-03-27): long-term sigma/flow/arb-probability/normalizer estimates plus short-term pool signals, asymmetric fees, probabilistic within-step ordering; no code. r3-d2/tune-tox (six toxicity constants at +-10/25 %, 500 seeds per cell): nothing clears 2 se; CH's toxicity block is a local optimum (TOX_QUAD -25 % -0.17, TOX_DECAY +25 % -1.0); gas max 185532 of 250000.\n- Earlier: vs CH ablate +0.0014, gate-grid -0.014, kalman-gate -0.211; vs YQ kalman +0.196, tune-decay +0.182 (n 1200), ablate +0.019, tune-asym -0.010, losers to -305; round 1 vs starter router-optimal +149.46, flow-estimate +124.42, fixed 75/75 +10.61 se 0.16, r1x edge-max +147.19; public shl0k28 -0.177 se 0.298 vs YQ, dipankar -232.88 and -5.05.\n- CALIBRATION (900000..909999, report-only): vanilla 342.26191722896806 se 0.5176; starter 367.91606344584477 se 0.5900; YQ 522.520303864629 se 0.917; CH, NP, NP2 pending (expect ~523.5 / ~524; 0..999 runs ~2.1 above). None of 525/527/528 reached.\n- BOARD MAP (official API, 743 entries): board = local 0..999 minus 0.7-3.7 (30 bps 338.60 / 342.26; Starter 367.18 / 367.92; Fixed75 378.94 / 380.1; YQ 523.21 / 524.63). 1st 528.40 needs ~529.5-530 local = +3.5 over NP: out of this goal's reach. Requester submits at +0.8 over CH on 4000 fresh seeds (NP +0.46; NP2 maybe ~+0.7 if additive) or +2 over YQ with a change of ours (NP +1.43).\n\nNEXT EPISODE (10, THE LAST): set finish = true and write up; spawn nothing. 1) Read everything handed; drop any item with paired.n 0 or under 500 (unmeasured). PROMOTION 4 = largest mean_diff >= 2 se with n >= 2000 vs NP: NP2 (r5-pri, pooled only if shas agree, else each item alone), np-two, or any r4 delta on 800000..801999; if two different deltas clear, the best file is one that was measured, never an untested union; if nothing landed, the best stays NP. 2) Write-up: the best Strategy.sol in full (rebuild from CH's URL + the edits; a rebuilt NP matches by its 0..999 score 526.0337302497852, by sha only if formatted identically: say so); paired gain over the starter (direct from r4-m1/replicate, else the chain) and over the previous best, with se, n, worst; ranked promotions table (YQ +154.69 se 0.95 vs starter; CH +0.962 se 0.021 vs YQ; NP +0.4645 se 0.0159 vs CH; a 4th if promoted); calibration numbers and the board map with the 525/527/528 statement; the candidate scoreboard (pub-scan table, tune-tox's null); methods (seeds, pairing, 2 se rule, tuning vs fresh blocks, calibration never used to choose); the setup-script deviation (briefs carried a compressed same-step version of the requester's 04:44Z script, Linux x86_64 only, uv venv --python 3.12; r5-pri's uses the requester's ziglang fallback as cc instead of micromamba gcc); what is missing (round 4 if still unmeasured; 1st not reached); citations: YQ, ChengHua, houseofjiao, shl0k28, dipankar, eliizabethzhang, 0xniki, The-CTra1n repos; Algebra medium post and LinkedIn pulse; Bruno I.

Tune only on 0..99999; promote only at >= 2 se, n >= 2000, on a fresh block.

Simulator: 10000 steps; GBM sigma U(0.000882,0.001008); an arb each step leaves spot at the band edge; Poisson(U(0.6,1.0)) retail split by the router between us and the fixed 30 bps pool.
