 "notes": "Episode 7/10. Entry: 63/400 items used, no refusals, 12 results handed; still running: e05-confirm-rs/a, e05-rs-search/c (d: 6 evals, = RS1, no information), e06-rs2-wide b/c/e (f held), e06-rs-side/a, e06-rs-post a/b. This episode spawns 5 batches, 26 items (89 used if admitted, 311 left). No simulation here.\n\nBASE IS RS2 (requester 23:50Z): `code` of https://api.imdnotdead.fun/artifacts/19f2ec857df536e8ab62ab1da89ec6623332521ce46849f15bccff402c63e1e5, sha256 f24b6ca198b744c380842c3a17964a6dc21f311bb04984b26733afa3fee8eaf2 (generator_source, params_exact there). Harness = `harness_source` of the V10 artifact https://api.imdnotdead.fun/artifacts/33f54e81f3372088e9eced52c0174f310ac348af98ef5727b73785c088679194. The requester is submitting RS2 and submits any file confirmed >= +0.07 over RS2 pooled over 4,000 fresh seeds, 0 OOG. Measure everything paired vs RS2.\n\nRESULTS READ (local paired vs Vanilla; none is a board result; handed code hashes recomputed, all match):\n- b24-a/b e06-confirm-rs2: exact RS2 on 5104000..5105999 and 5106000..5107999: vs RS1 +0.0915 se 0.0115, +0.0878 se 0.0114; vs V10 +0.1639 se 0.0121, +0.1627 se 0.0125; retail +1.47 / arb -1.32 vs V10; CH exact; 0 halts; afterSwap 203,671, init 243,099. Pooled n 4,000: about +0.090 vs RS1, +0.163 vs V10.\n- b25-a/d e06-rs2-wide: a (177 evals) held-out -0.0042 se 0.0144 vs RS2; d (69 evals) -0.0211 se 0.0132. The 7-parameter RS family is at its plateau; do not widen it again.\n- b26-b e06-rs-side/b: per-side lambda split -0.0254 se 0.0137 vs RS2, flat in side_mix of either sign. Negative (a still running).\n- b22-a/b e05-rs-ablate (RS1, 512 seeds each): the gain is the cleaned SIZE replacement (count+size minus count-only +0.35 / +0.30); count-only loses -0.20 / -0.16 vs V10; RS1's missing-flow correction is dead weight (-0.066 / -0.065, se 0.013); RS2 bounds it at 1.5x and rs2-wide/a without it ties RS2: removing it buys gas, not edge.\n- b23 e05-design-impl (on V10, 512 held-out): cont-a table -0.044 se 0.013; cont-b polynomial -0.003 se 0.003 (unsafe variants -0.23..-1.7); tail-a DAR and tail-b Jensen: every enabled arm -0.13..-30, identity frozen. RETIRED: two-step continuation overlays, size-tail quote targets.\nPattern: every overlay that moves quotes trades retail for arb one for one; only replacing short-memory flow inputs by long-memory cleaned ones nets a gain, in tenths.\n\nHONEST STATUS: local +0.31 over STACK (V10 +0.136, RS1 +0.085, RS2 +0.090). Board 519.85 with V10; RS2 expected near 520.0; 26th about +0.27 above that; 10th about +4.6 more. No in-family path to +5 has appeared in four goals.\n\nFROM THE EARLIER WRITE-UPS (re-read): CH (ChengHua926's public fork) is the same V2/NP2 family and scores below STACK (V2 526.94 vs CH 525.53 on seeds 0..999): no shortcut. The board's top 10 cluster as ONE low-variability fee family (1st 528.399, 2nd 528.362, 5th 528.099), which looks like a shared ancestor. Earlier goals read only a few entrants' repos (one leader's public repo scored about 3.9 below his board entry). The challenge repo has 74 public forks (GitHub API); 28 were pushed after upstream's last commit, some large and active for months (VictorQian03 to May 2026, jaoz 25 MB, sisyphusSmiling 13 MB, solosage1, giorgoschionas). Nobody has swept them: the one untried source of whole fee rules.\n\nDECISIONS:\n(1) e07-fork-mine, 12 items: f1..f7 take 4 named forks each (the 28 pushed ones); `rest` checks the other 46 by branch head; h1..h4 take 8 again (the largest, and CH's) on another machine, older files too. Each collects every .sol defining afterSwap, validates, scores on common seeds 900000..900031 against RS2, runs its best 3 and RS2 on 901000..901255, returns the best file's code, licence and mechanism. Same seeds everywhere, so figures compare across items. Its first five items are its canary.\n(2) e07-public-search, 4 items (repos, code, writeups, entrants): non-fork repositories, gists, write-ups, the top-30 entrants' public pages; mechanisms only with URL and quote; any code measured on the same common seeds.\n(3) e07-run-anchor, 6 items (sigma, act, tox x a/b): RS2's retention ran to its upper bound, so the fee prefers a run's constants; V10's sigmaHat (decay 0.69), actEma/sizeHat (0.53), toxEma (0.91) are short. Anchor each to a running mean over the run with a searched deviation gain; identity = RS2.\n(4) e07-vol-flow a/b: board-fit says leaders' fee moves more with volatility (4.8-6.8 vs 3.2) and less with flow (0.2-0.4 vs 1.4) at a lower mean: gains (1+a) on sigma terms, (1-b) on flow terms, minus c, searched jointly.\n(5) e07-lean-tail a/b: both earlier write-ups asked for a look at tail runs (our bid-ask lean 17-19 bps where 1st gains 15-18); never done. Scan 2,000 runs, characterise the 20 largest-lean runs, test a governor acting only there.\nNo cancellations.\n\nTHIRD-PARTY CODE: a mined file is another entrant's work and the challenge repo carries no licence. Treat mined files as evidence and a source of mechanisms to port onto RS2; tell the requester author and licence, and leave any verbatim submission to them (my advice: port, do not submit another entrant's file as ours).\n\nLEDGER. Confirmation blocks (half-open, 2,000, spent once allocated): [5000000,5036000) spent/quarantined; [5036000,5100000) reserved unused; 5100000 confirm-rs/a (running); 5102000, 5104000, 5106000 used. NEXT FREE 5108000; none allocated this episode. Tuning (inclusive): common mining seeds 900000..900031 and 901000..901255 (reuse for any later ranking of mined files); run-anchor sigma-a 910000, sigma-b 915000, act-a 920000, act-b 925000, tox-a 950000, tox-b 955000; vol-flow a 930000, b 935000; lean-tail a 940000, b 945000 (5,000-wide bands: search s..s+2999, re-check s+3000..s+3255, held-out s+4000..s+4511, parity s+4600..s+4631; lean-tail scan s..s+1999, screen s+2000..s+2255). NEXT FREE tuning band 960000; after 999999 use the untouched tails s+6100..s+9999 of bands 640000..899999.\n\nEPISODE 8 PLAN (two episodes remain after it; a requester note can start it before the batches settle: then act on what is in, do not respawn what still runs, wake on the rest):\n(a) Read blocked first; a blocked fork-mine slice is re-run in a new batch with the same fork list.\n(b) Mined files: rank all top3 entries by paired mean vs RS2 on 901000..901255. For any file with 0 OOG beating RS2 by > 3 se, spawn at once (i) a two-machine confirmation of the exact file vs RS2 on 5108000 and 5110000 (5112000, 5114000 for a second file), CH calibration in the brief; (ii) two port items per distinct mechanism: the mechanism on RS2, or RS2's retail state on the mined rule if that base is higher, 512 held-out tuning seeds; (iii) if it is > +1 ahead, a CMA search around its constants on 2-4 machines. Give the requester file, author and licence in notes.\n(c) If nothing mined beats RS2, record the fork network as swept and port only mechanisms whose source reports a board score above ours.\n(d) run-anchor, vol-flow, lean-tail, rs-post, rs-side/a: frozen held-out vs RS2 > 2 se and >= +0.05 -> two-block confirmation vs RS2; smaller but > 2 se -> one integration item pair with the other positives; flat or negative -> retire with its artifact.\n(e) Not requested (30 reads max): e06-rs2-wide c/e/f, e05-rs-search/c, e05-confirm-rs/a; ask only if rs2-wide/b beats RS2.\n(f) Budget: 311 left; spend up to 60-100 on ports and searches of anything mined that beats RS2; keep 40 for confirmations and a final gas check. Episode 10 sets finish: best confirmed file, sha256, provenance, the honest gap to the top 10.\nRules in force: briefs < 3,000 chars with the verbatim setup script (this episode's are 2,958-2,970); every {{var}} in every item; two items per idea; CH calibration (seeds 0..999 = 525.5258821780834) in every confirm brief; no seed >= 5000000 for tuning; never pool different hashes; afterSwap < 235k, init < 245k (RS2 init 243,099: no new write in afterInitialize); any OOG invalidates a hash. finish=false: no top-ten result exists.",
