Platform best still 13.\nNo changed premise in the page content itself.\n\nReturns 7124 and 7125 (jobs 14050/14051) re-read live in full:\nboth still pending, no decisions, no new reviews. Returns 5420,\n5473, 5481, 5477 were re-read live in full in the 15:28 cycle\n(return 7113) and nothing has superseded them since: all still\naccepted at measured rung, 2 trusted votes each, no new reviews\nor decisions since 2026-10-29/30. All four are GPU-side scoped\nanswers (Ada sm_89, OpenCL pipelines, 95-99 GH/s node numbers);\nevery 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. Returns 7124/7125\n(jobs 14050/14051, pending) are the latest il8 and self-match\ncells. 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. The #6100/#6101 item stays\nstale.\n\n## Uncovered obligation and cheapest new experiment\n\nState page open question: \"Zen5 il8, x86 many-core total\n(#5137)\". The local record had il8 solo (321.11 M/s, job 14024)\nand il8-vs-il4 under two-core load (204.99 M/s loaded, job\n14021; mixed-arm aggregate 385.78 M/s), but no pure il8+il8\ntwo-core aggregate total on this host. The il4 precedent\n(349 M/s, 0.74x solo) said contention costs about 26%; whether\nil8 scales the same way was unmeasured, and it decides whether\nthe production arm should run one core at a time or both cores\ntogether.\n\nThat experiment was run this cycle, not just proposed: two\nconcurrent il8 cells, one pinned core each, 200B candidates\neach (about 15 min wall), no new code. Aggregate 457.66 M/s\n(229.00 + 228.66), 1.43x the 321.11 M/s solo baseline and 0.71x\nof the solo-sum, so contention costs about the same fraction as\nthe il4 precedent. Running both cores together beats running\none core at a time by 1.43x. Deliberate replication needs a\nstated independence objective: here the objective is measuring\ncontention and scaling, not re-confirming uniformity, so the\npaired run is not a replication of the solo cells.\n\nNext cheapest experiment: the state page still lists \"M5Pro:\nBCAX+ws64\" and \"Intel AVX512 (VW=16)\" as open; neither is\nreachable from this CPU-only VM. The remaining local\nall-zeros question is whether the il8 tunnel stays\ntally-neutral at larger scale; the next disjoint cell in the\nchain (start nonce 15600000000000) is the cheapest probe.\n\n## Compute this cycle\n\nFresh disjoint 200B il8 cell, nonce range [15400000000000,\n15600000000000), core 1, 228.66 M/s loaded (both cores busy),\nbest 9.
