  "notes": "Episode 6/10. Read state, schema, three results and requester notes; no refusals. 32/400 items used; 9 running and 7 waiting across 10 unsettled batches. Add 4 independent research items in 2 small batches: total 36, 364 left if accepted. Four decision episodes remain after this one. Targets +5/+8.7 vs V2. No confirmed positive mapping gain, submission or trunk. Wake cap respected:10 batches. No local simulation here.\n\nStanding method: exact V2 comparator SHA256 28417e116f57f1029fdd1803832e852574902c1ae7253c05657f317db76da4ab, never a slim comparator. Pinned amm-challenge commit 6b6921f8d463314aa7c96234e1be25a25245f704; each strategy alone vs Vanilla via run_batch(...,8), identical direct per-seed configs (default_rng(seed): size,rate,sigma; price seed, retail seed+1), full 10000 steps. Requester corrections in goal.json permit candidate OOG<=V2 OOG on identical seeds for experimental evidence; every new brief contains the required verbatim override. Other errors invalidate. Submission still requires candidate OOG=0, paired gain>=0.3 and >2SE on 4000 fresh seeds. All new briefs include the exact rustup->micromamba fallback line; setup failure is blocked{step,error}, n=0, not a losing design. Freeze before holdout; no holdout tuning.\n\nHanded b12-control=e04-harness-repair/control, artifact db62deadd0a3ec885ad69bd3917fee793a924ead522776d73cc09110923e1e86. Hash verified locally; code is exact V2. On 10000..10255, independent V2 runs have all edges identical: n256, mean/se0; OOG7 each, afterSwap max243554, init236377, Vanilla/other errors0. Per-seed counters equal global; retail+arb reconciles within7.674e-12. Mean total523.2153137188661. This is a reproducibility control, not improvement. It supplies source_files [{path,content}]: setup.sh, full instrumentation.patch, corrected harness.py, tests.py and forced-error diagnostics. Requested configs only, chunks64, --ref V2.sol, half-open range. Forced OOG/revert/bad return detected; no holdout. Plane flags its sources; measurements remain worker evidence. Code inspection found counters_per_seed_match_global and reconciliation are reported but NOT part of validity(); new base-verification item will gate them and add per-seed retail volume for terciles. Use this artifact, not the obsolete 02c134d9 harness that aborts on baseline OOG/allocates millions of configs.\n\nHanded b07-slim=e02-gas-room/slim, artifact c5114d6f2f9230073d40f09e3a4bd09dad08ee3833d8dc9faa8779f6d7b0b132. All source hashes checked. On10000..10511 n512: V2 swap max243701/OOG13, init236377. Dropping init zero writes is exactly zero diff, init220932, swap/OOG unchanged. Packing prior spot above timestamp removes OOG: mean+0.0015018653465587173, SE0.001433047571710032, only9 formerly OOG seeds differ, max abs0.7304987692035638. Adding floor sqrt preserves packing-step edges exactly. Final sha e8ea46c8053587c7c514a1c08b5d8fce2566453b6eea4ad50fb74c49d2017a76: swap max233970, init220944, OOG/other0. Headroom16030; not evidence of an economically better mapping. Old OOG objection superseded. Test identity on non-OOG seeds and separately labelled high-gas diagnostics.\n\nHanded b06-b2=e02-design-b-edge/b2, artifact 22903683526e3817ce2cb099f097578ce78fa53121bac16c898e3bda0095560a. Source sha42938ca2214742654b303fe3dc87d284ef9db318e0239f2801f06fd7a2bf815a verified. Linear router-share, per-side immediate-edge optimizer; removed direction/activity/toxicity. Three variants on 40000..40255: -43.549 SE.643, -49.399 SE.578, -94.959 SE1.464. Best frozen v5 partial holdout 4070000..4070399 n400: -43.975 SE.481; worst seed4070035 -83.666. Candidate max231212/OOG0; V2 max243469/OOG5; other reported halts/reverts0. No top2 stage; n2000 NOT achieved (time/command limit). Overwritten earlier variants had32104 OOG. Retire this specific implementation as a strong negative, never promote or claim completed confirmation. Remaining Design B items test different forms and continue. Do not generalize this to every expected-edge rule.\n\nLatest requester 03:00Z adds usable gas headroom and negative next-mix evidence. Fetched/checked https://api.imd.fun/artifacts/f09f39f5092e5b1e56f156df10f397e5df0e194afa630ab24fc699adfd980d31. Reconstructed G IN MEMORY from code_GN: delete two MIX_ constants, block from '// Mix the next retail quote' until slots[0], and helpers from '// Poisson survival ratio' until _compressTailWithSlope. Exact sha610c1905e7dd5559b84e40a3b2d6f8e0b53a7b0ac7574ae33b6c1770a28367cb matches shas.G. Compared with slim: additionally removes slots[11]=pHat (REVERT_U=0) and uses fixed seven-step floor sqrt. G swap peak213179/OOG0 is measured on ONLY100 identity seeds, not2000; GN peak221157/OOG0 covers2000. G matches V2 on0..99 at diagnostic1M gas exactly; capped differences at96/99 reflect V2 OOG. GN (G+next-mix) on3300000..3301999: -0.04741280122016272 SE0.024606373526880866 vs V2; removing skew adds -0.06776927216760155 SE0.008352973795498791. Don't stack next-mix or zero skew. Calibration: exact V2 on0..999 mean526.9433475904315, OOG18. Reproduce this before relying on new G measurements. These calibration seeds are not tuning/holdout.\n\nDecisions: e06-g-base/verify verifies frozen G, calibration, 512 training pairs, diagnostic identity, math/packing bounds and strengthened harness; no holdout/gain claim. e06-continuation/h2,h4,h8 are three small independent copies of a NEW replacement mapping, differing in offline lookahead horizon (2/4/8 steps). Hypothesis: account for arb recentering's future retail benefit, which a myopic optimizer omits. Use small joint bid/ask action tables, exact router and execution edge, lognormal retail sizes and unknown remaining-print count. Runtime gets observable V2 estimates only; latent variables integrated offline, preserve direction skew, no online optimizer. Each gets bounded training, H=1 ablation and fresh n2000; no widening before valid gain. Workers reconstruct G/use b12 independently; no dependency on the audit.\n\nKeep all16 pending items; queue latency and negative GN do not establish their different mappings failed. No cancellation or duplication. Read all16 plus4 new results (20). Wake includes both new batches and8 older batches; omitted pos-scale batches are still read. afterMinutes90 schedules the next episode; no clock wait here.\n\nSeed ledger: ALL4000000..4259999 remain allocated/retired; never reassign, even unused. Pending old blocks: phase4080000, routing4090000, corridor4100000, a3=4130000, b1=4140000, b2=4150000, s1=4160000, e04a1=4170000, table4190000; p1=4200000,p2=4210000,p3=4220000,t1=4230000,t2=4240000,s2=4250000. Each old item confirms first2000 of its10k block. New h2=4260000..4261999 (reserve through4269999), h4=4270000..4271999 (through4279999), h8=4280000..4281999 (through4289999). NEXT FREE4290000. Training h2=10000..10063/12000..12255; h4=20000..20063/22000..22255; h8=30000..30063/32000..32255. Model fitting/tuning restricted to assigned training, never confirmation. G control uses10000..10511; no fresh block.\n\nNext episode: read blocked first, then calibration, source hashes, frozen timing, exact configs/paired n, complete gas/error counters and reconciliation. Partial tests are unconfirmed. Check H=1 vs longer-horizon ablation to distinguish continuation benefit from generic retuning. Board total-edge targets vs V2 by V2 retail-volume tercile: first +7.293/+8.7183/+10.1415; tenth +4.1639/+5.0149/+5.7501. Board API gives volumes, not retail/arb edge; use local attribution, never fee*volume proxies. If a family gains>1 and >2SE, widen a bounded canary batch AND independently confirm its frozen zero-OOG finalist on4000 new seeds from4290000 up. Smaller credible gain>=.3 also earns submission-grade confirmation; don't discard it for missing+5. Reserve final episodes for reproduction and write-up. If all measured designs lose, report that honestly; never substitute a gas-only control as the requested structural win. finish=false.",
