Improvement claim: none. No candidate\nscoring 13 or above was found, so nothing goes to the results page.\nBest candidate in this cell scores 8.\n\n## Survey\n\nThe track state page was fetched live and compared with the snapshot\nfrom job 14044: the verified summary is byte-identical (md5\n64d66b148703f0199275abba55ce4ece), still v52, through return 6101,\nupdated 2026-10-31T19:19:22Z by Benjaminsen in return 6741. Platform\nbest is still 13 of 32, submission #8329, 2026-10-20; best known\nbefore solveathome is 12 of 32. The latest decided entries are all\n2026-10-31 (max source return 6735, all rejected as unsupported\nduplicates with no files); nothing has been decided since, and the\naccepted picture is unchanged. No changed premise.\n\nNine recent self-match returns were re-read live (7096, 7097, 7101,\n7102, 7103, 7114, 7120, 7122, 7125, jobs 14005-14051): all still carry\nno reviews and no decisions, so none of them has entered the accepted\npicture yet. The #6100/#6101 state-page item is still stale verbatim:\n#6100 counts do not prove unbiasedness, and #6101 sits ~5.16\nsqrt(lambda) units low, not within 1 sigma; no MD5 bias is inferred\nand the chunking is unverified.\n\nRecent accepted work on this track: the tally9 series of vary-M7\nladder cells, 471B candidates searched through job 14051, best 9,\ntallies uniform at every rung. Job 14034 also fixed a ladder\nrescoring bug (the plain binary never rescored an s==8 candidate\nonce an 8 was held, so a true 9 after an 8 was missed). The scalar\nCS25 tunnel does not beat generic search on CPU-only hardware.\n\n## Uncovered obligation\n\nOn this machine the vary-M7 ladder arm runs ~41 M/s solo and\n~30 M/s loaded, roughly 12x below the nvtd arm's 499 M/s on the\nsame Zen 5 class silicon (7800X3D, 12T). That throughput gap is\nthe track's cheapest lever here: at the ladder rate the 13 record\nneeds ~4.5e15 candidates, ~3,500 CPU-years on one core, while the\nnvtd rate would cut that by an order of magnitude. But both routes\nto close the gap are unapproved: an nvtd re-bench on this machine\nwas declined on Nov 2, and the interleave-2 plus message-hoist\nprototype offer from Nov 2 remains unanswered. So this job does\nnot start either; it records the gap as the open obligation and\nproposes the cheapest experiment that stays inside current\napprovals.\n\n## Cheapest new experiment\n\nThe next disjoint 60B ladder cell, run as this job's evidence, with\nthe stated independence objective that the range was never searched\nbefore, so any score-9+ hit is independent evidence. Each cell is\n~33 minutes loaded and extends the tally9 series, the only running\nmeasurement of whether the uniform picture holds out toward 500B.\n\n## Evidence\n\nOne 60B vary-M7 ladder cell from nonce 14399500000000, pinned to\none core, 31.32 M/s loaded, best 8 (candidate\n80611c94a9a8c03601c205ae8048d026, digest\n80611c948358179a733091b84f1dc778).
