  "notes": "EPISODE 10 (2026-11-07), THE LAST: finish = true, nothing spawned. STATE: round 4 (31 NP-delta items) produced NO measurement: all 10 handed results (np-two, np-sigma, np-lambda, np-first, np-nhat, np-clip, fill-rate, exact-stale, phase2, lite9) and r4-m1/calib-b came back blocked at the setup script with n 0 (8 x `tar: Cannot change ownership to uid 1001: Invalid argument` at the uv archive, the bug the requester fixed at 05:19Z with `tar --no-same-owner`; np-lambda: micromamba tar needs bzip2, absent; fill-rate: rustup needs procfs, absent; np-first: a Mac, platform check). The remaining 20 round-4 items and r4-trunk (code wave writing best/Strategy.sol = NP) are still running; r5-pri (NP2 = CH + norm-phat + two-print at 4000 seeds, the requester's 04:55Z priority) never started (4 waiting) and is cancelled here: no episode remains to read it. Round-3 stragglers handed now (all vs CH on 600000..601999): fees-used +0.2993 se 0.0381 but n 300 only (not promotable; its idea: on a first-in-step print with ret > 2*sigmaHat use alpha 0.20 instead of 0.27, sha d6666c0c, 0..999 = 525.80 unpaired, +0.275 over CH); sigma-elapsed (elapsed-normalised variance, sha 3d8dfb6a) -0.2866 se 0.0177 n 2000, 0..999 525.25: loser; tune-base (5 base constants +-25 %, n 500 per cell): every direction negative (LAMBDA_COEF -25 % -2.11, SIGMA_COEF +-25 % -0.54, BASE_FEE -25 % -0.20), CH returned unchanged; tune-est (1-CPU machine, n 30): nothing clears, LAMBDA_CAP looks sensitive (-0.56 se 0.11 at -25 %); cma-residual (1 CPU, 30 candidates at n 6, sigma 0.1 over 33 constants): every candidate 0.4 to 10 below CH, CH sits in a sharp basin, CH returned unchanged. NO PROMOTION 4: round 4 is unscored, not negative. BEST = NP.\n\nWRITE-UP (write it from this; the read list carries the results it cites).\nBEST FILE: NP = CH plus 9 lines inserted right before `uint256 tradeRatio = ...` in afterSwap: `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 retail print was split by the router so fee-adjusted marginal prices equalise, which reveals the 30 bps pool's spot: a second observation of the fair price, blended 0.1 into pHat; 0.3 -0.83, 0.5 -6.0, a hard clamp -23.5).

Every standalone mechanism lands 5-150 below the YQ family.\nMETHODS: `amm-match run --simulations N` = seeds 0..N-1 (numpy default_rng(seed) draws size, rate, sigma; Rust price seed = seed, retail seed+1); other ranges via amm_sim_rs.run_batch with explicit seeds; runs bit-reproducible across machines (anchors2 a/b identical). Tuning only on 0..99999 (r3 10000.., r4 30000..); confirmation on fresh blocks e*100000..+1999 per episode; promote only at paired mean_diff >= 2 se, n >= 2000; 900000..909999 report-only. DEVIATIONS to state: briefs carried a compressed same-step version of the requester's 04:44Z setup script (Linux x86_64 only, uv release binary, micromamba gcc or ziglang cc, rustup minimal in scratch/, `uv venv --python 3.12`); it lacked `tar --no-same-owner`, which blocked round 4 on root-in-container machines. Blocking rate: ~40 % of all build items never ran the simulator.\nMISSING / NEXT STEPS: (1) rerun round 4 (31 NP deltas) and r5-pri (NP2 on 1000000..1003999 + calibration 900000..909999) with the 05:19Z script (`tar --no-same-owner -xz` for uv, `-xj` for micromamba, bzip2 fallback via python tarfile, early stop without procfs); (2) confirm fees-used on 600300..601999 (n 1700) and, if it clears, NP + fees-used + two-print as one measured file; (3) CMA-ES/coordinate tuning needs >= 8 cores and n >= 300 per cell; (4) 1st place is +3.5 locally away: needs a new mechanism, not constants.\nCITATIONS: benedictbrady/amm-challenge 6b6921f8; paradigm.xyz/puzzles/amm (+about, leaderboard API); repos jiayaoqijia/amm-challenge-yq 3e9dc7d5, ChengHua926/amm-challenge d34a5199, houseofjiao 4f41eb91, shl0k28 9c4be0b6, dipankar, eliizabethzhang 7156ff03, 0xniki 56ca9d16, The-CTra1n cd1bf7bc; Algebra medium.com/@crypto_algebra and LinkedIn pulse (2026-03-27); Bruno I.
