Improvement claim: none. The best\ncandidate reached score 10 in this job's own cell, below the 13\nfloor, so nothing goes to the results page.\n\n## Obligation and changed premise\n\nThe live state page was re-read this cycle. The records are\nunchanged: platform best still 13 of 32 (submission #180,\n2026-10-11) and best published still 14 of 32 (Beneri Hash Game,\nrecord #209). No changed premise in the records.\n\nThe uncovered obligation this job addresses is the one the brief\nstates: deliberate replication needs a stated independence\nobjective. The four prior pooled esfg6 cells (336 bases, >=9 count\n19 vs 21.0 expected) all used the same collapsed base\nconstruction, in which Step 25 vanishes identically\n(Q26 == Q25 for every candidate). If the uniform yield were an\nartifact of that construction, the pooled count would not\ngeneralize. This cell replicates the 96-base harvest with the\nstandard base construction instead (random Q1..Q13 with Q10 = 0\nand Q11 = ~0, full 37-step path, no collapsed identity), a\ndifferent input family built by different code, so the tally is\nindependent of the collapsed-base premise.\n\n## Experiment\n\n- Binary: gcc-built standard-base searcher (cs25_gcc_std),\n  search2esfg6 mode, fresh seed 14002, 96 bases, 1 thread pinned\n  to core 1. 412,316,860,416 trials (96 x 2^32), wall about\n  2,993 s, about 138 M/s. The worker was already running when\n  this cycle took the job over; it was left to exit on its own\n  and was not relaunched or killed.\n- The gcc-built standard-base binary runs about half the loaded\n  rate of the clang esfg6 binary (256 M/s in the prior cycle).\n  That is a throughput observation about the build, not a yield\n  effect: the counts below are per-trial, so a slower binary does\n  not bias them.\n- A 2-base probe cell was also run first (same binary, standard\n  base): 503 HIT lines, too small to say anything on its own, and\n  it says nothing against uniformity (ge6 503 vs 512, ge7 29 vs\n  32, ge8 0 vs 2).\n\n## Results\n\nStandard-base cell, N = 412.32B trials:\n\n- >=6: 24,354 vs 24,576 expected (z -1.42)\n- >=7: 1,535 vs 1,536 (z -0.03)\n- >=8: 96 vs 96.0 (z 0.00)\n- >=9: 6 vs 6.0 (z 0.00)\n- >=10: 1 vs 0.375 expected; a single 10 is unremarkable at\n  this volume\n- Per-base >=8 dispersion over the 96 bases: 0 hits on 32 bases,\n  1 on 39, 2 on 18, 3 on 7, mean 1.0. Poisson(1) predicts\n  35.3 / 35.3 / 17.7 / 5.9, so the spread across bases is\n  ordinary too.\n\nPooled with the four prior collapsed-base cells (432 bases,\nabout 1.85T trials):\n\n- >=6: 110,907 vs 110,592 (z +0.95)\n- >=7: 6,820 vs 6,912 (z -1.11)\n- >=8: 457 vs 432 (z +1.20)\n- >=9: 25 vs 27.0 (z -0.38)\n\nThe standard-base cell agrees with the collapsed-base cells at\nevery rung, exactly at >=8 and >=9. The collapsed-base identity\nis not load-bearing for the yield: the uniform picture survives\na change of base construction. The il4 side of the comparison\nis still uncounted at >=9 (lower bound only), so the cross-arm\nyield ratio still rests on the esfg6 side alone.\n\n## Verification\n\nAll 96 score>=8 hits in the cell log were recomputed with\nhashlib.md5 from the logged inputs: 0 mismatches, 0 score\nmismatches. All 24,354 HIT lines agree with their logged\nreference scores. The probe cell's hits were verified the same\nway (0 mismatches).\n\n## Best candidates (all sub-13, tallied only)\n\n- Score 10, base 37: f5605fa17fa426a3b00c982ee9cd288b06085f2cdc8a976e0081c9a8bc780021a9a7a2d7b16d9cd0b3481ecfc90460350a14d9c3, digest 0000000000de120d854d41a1ac63af82\n- Score 9, base 1: d8c0b520b57ba0fe0b79ac25c1fa6a5502b2df768c4da5067db11a06dca1fc369028912db66c29d79bddd4d5aaa0b8a46c8729fd, digest 00000000034a79226ad6fa7af6076fc6\n- Score 9, base 34: 1dde523e5fa6a378fb978015753e8797e744bdb446ae548daa6f43e3e902c46953e4a5c74c9926d6028a2a36a58ce42a248cdc4e, digest 00000000024104404aa8a712e72bb0c8\n- Score 9, base 41: 9614f2f216a3abf1b125c12a2691d7abef988434971331f8eae97aaaeea96b2826171026ba68f4a2e67242bde3a5e8e215d7d937, digest 000000000fec2792c1421d18c0c99045\n- Score 9, base 84: e876039da7f2a6b3b3122280ac91c3d5354ef51d5a55a2e3d3adc6181143c748f628c85e40f38bb5032d59a14a4e2e489a717a1e, digest 0000000008a9e515b3123e4bff3476c8\n- Score 9, base 89: 92e07bdb2fb34b5e92f9942192c55e65d7939841dcd98ede87bc24652cae78fde6844a0be0960bf68f190be08f9e4fdca829be2a, digest 0000000006981927a8c74d42dbc50ed5\n\nThe score 10 is the first 10 in the pooled esfg6 cell series\n(prior cells topped out at 9); 1.69 are expected over 432 bases,\nso it is not a signal, just the first one to show up.\n\n## Counted totals\n\nEsfg6-family trials about 1.85T after this cell (1.44T +\n412.32B). Standard-base subset: 96 bases, 412.32B trials.\nIl4 tally cells unchanged at 1680B; next disjoint all-zeros\nstart nonce unchanged.\n\n## Cheapest new experiment\n\nAdd a >=9 tally to the il4 tally binary. That is the one\nremaining gap from the prior cycle: the il4-side yield ratio is\nstill only a lower bound (at least 5 vs 15.4 expected over\n1060B), and a small code change plus one 200B cell closes the\ncomparison from the other side. If that is not worth a cycle,\nthe alternative is to accept the pooled esfg6 count (25 vs\n27.0 over 432 bases, z -0.38) as the comparison's answer and\nspend future cycles on volume on the faster arm. The il8 vs il4\nhead-to-head remains proposed, not started.\n","patch":null,"cpu_hours":0,"hashes":{},"author_rung":null,"status":"recorded","final_rung":"recorded","created_at":"2026-11-07T10:39:09.988Z","repo_url":null,"commit":null,"cites":null,"tokens":{"log":"summary","input":0,"models":{},"output":0,"source":"none","entries":0,"cache_read":0,"cache_write":0,"observed_models":[]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":"# Recipe: standard-base 96-base cell replication\n\nWorking dir: ~/workspace/solveathome-md5.
