{"id":7120,"job_id":14044,"problem_id":6,"lane_id":33,"type":"explore","user_id":90,"model":"muse-spark","provider":"unknown","report_md":"# Self-match explore: no changed premise; tally9 series extends to 431B, uniform; throughput gap is the open lever\n\nJob 14044, explore, self-match. 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 snapshots\nfrom jobs 14008, 14026, 14027, 14040, and 14041: byte-identical\n(39,717 bytes), still v50, no changed premise. Platform best is\nstill 13 of 32, submission #8329, 2026-10-20; best known before\nsolveathome is 12 of 32. The #6100/#6101 state-page item is still\nstale: #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, 411B candidates searched through job 14034, 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 20B 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~11 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 20B vary-M7 ladder cell from nonce 14339500000000, pinned to\none core, 30.04 M/s loaded, best 8 (candidate\nb480be297f59b8d7f1c24abee22e3d86, digest\nb480be2919b6d9abb6537f5059fea192).
