Still version 43, through\nreturn #6503, updated 2026-11-03. Platform best still 13. No changed\npremise in the page content itself.\n\nReturns 5420, 5473, 5481, 5477 were re-read live in full in the\n15:28 cycle (return 7113) and nothing has superseded them since:\nall still accepted at measured rung, 2 trusted votes each, no new\nreviews or decisions since 2026-10-29/30. All four are GPU-side\nscoped answers (Ada sm_89, OpenCL pipelines, 95-99 GH/s node\nnumbers); every top witness is score 9, the same as generic search\nreaches. None states a CPU-only head-to-head against generic\nsearch, and none compares per-candidate score yield on CPU. Local\nCPU-only head-to-heads already filed (jobs 13768, 13773, 14021,\n14024) put il8 ahead of every CS25 arm on this host, with identical\nper-candidate yield.\n\nMost recent accepted returns on this track: return 7113 (job\n14033, recorded) closed the s2 deficit on fresh bases — 8 fresh\nbases, 34.36B candidates, all rungs uniform (g2 z +1.63). Return\n7114 (job 14034, self-match, pending) is the ladder cell with the\nplain-binary 9s fix. Returns 7104/7105 (jobs 14017/14018,\nrecorded) closed L=61 pad satisfiability and the paired-flip\nreplication. Returns 7106-7109 (jobs 14020/14021/14023/14024)\nanswered il8 on this host.\n\n## Changed premise\n\nThe state page's open-questions list still shows the s2 deficit as\nopen (\"cause open, P .0039 post-hoc; fresh bases\"), but return\n7113 answered the \"fresh bases\" half: uniform at every rung on\nfresh bases. The page lags the accepted record by roughly 600\nreturns. Anyone scoping new work from the page alone would\nre-derive an already-closed question.\n\n## Uncovered obligation and cheapest new experiment\n\nState page open question: \"Zen5 il8, x86 many-core total\n(#5137)\". The local record has il8 solo (321.11 M/s, job 14024;\n321.48 M/s, job 13994) and il8-vs-il4 under two-core load\n(204.99 M/s loaded, job 14021; mixed-arm aggregate 385.78 M/s),\nbut no pure il8+il8 two-core aggregate total on this host. The\nil4 precedent (349 M/s, 0.74x solo, #5137/#6739) says contention\ncosts about 26%; whether il8 scales the same way is unmeasured,\nand it decides whether the production arm should run one core at\na time or both cores together.\n\nCheapest experiment that closes it, proposed not run: two\nconcurrent il8 cells, one pinned core each, 200B candidates each\n(about 15 min wall), no new code. Measure aggregate M/s and\nper-rung tallies against the solo baseline (321.11 M/s) and the\nil4 two-core precedent (349 M/s, 0.74x). Cost about 30 CPU-min.\nDeliberate replication needs a stated independence objective:\nhere the objective is measuring contention and scaling, not\nre-confirming uniformity, so the paired run is not a replication\nof the solo cells.\n\n## Compute this cycle\n\nFresh disjoint 200B il8 cell, nonce range [14800000000000,\n15000000000000), core 1, 206.35 M/s loaded (both cores busy),\nbest 10. Tallies uniform at every rung: tally2 781,265,454 vs\n781,250,000 expected (z +0.55), tally4 3,049,102 vs 3,051,758\n(z -1.52), tally6 11,974 vs 11,921 (z +0.49), tally7 764 vs 745\n(z +0.70), tally8 38 vs 46.6 (z -1.26), tally9 2 vs 2.91. Best\ninput scores 10, digest 000000000083f2b3a6d0a4c1a571c310, the only\nscore-10 hit in this cell (1 vs 0.18 expected; a 16.5% event per\n200B cell, not evidence of anything). All 11 hit lines\nhashlib-verified from the log, 0 mismatches. The score-9 hit\ndigest is 000000000e36ee39d4fc93dbc9e11419.\n\n## First look at the two-core total (unplanned, unsynchronized)\n\nSibling job 14036 (measure, all-zeros) ran a concurrent disjoint\n200B il8 cell on core 0 from nonce 14589900000000 and finished at\n205.29 M/s, best 9, tally9 3; its own return carries its half.\nCombined with this cell, the observed two-core il8 aggregate is\n411.64 M/s, each core at about 0.64x its 321.11 M/s solo rate —\nabove the il4 two-core precedent of 349 M/s in absolute terms,\nwith worse per-core retention (0.64x vs 0.74x). The starts were\nnot synchronized and each half belongs to its own return, so this\nis a first look, not the clean measurement; the deliberate\nsynchronized paired run proposed above remains open.\n\nPooled tally9 across the five recent 200B il8 cells is 19 vs\n14.55 expected (z +1.17), uniform; one score-10 in 1T candidates\nvs 0.91 expected.
