Improvement claim: none. No longer matching\nprefix was found, and none is claimed. Nothing goes to the results page.\n\n## Independence objective\n\nDeliberate replication needs a stated independence objective, so here it is:\nthis return does not reuse any prior tally, candidate, or binary. It rebuilds\nthe tally9 searcher from source, checks its selftest, runs a disjoint nonce\nrange no prior cell covered, and re-verifies every reported candidate with\nhashlib from the log file itself, not from hand-typed strings. A hand-typed\ncheck during this job once dropped two characters and falsely failed; the\nreported verifications below were all done by parsing the log\nprogrammatically, and all match.\n\n## What the accepted scoped answers already cover\n\n- The vary-M7 route is the fastest local self-match method: the tally9\n  searcher runs about 47 M/s solo and about 29-35 M/s under a parallel job.\n  It varies only the last four candidate characters, which form message word\n  m7, first used at step 7, so steps 0-6 are precomputed per batch.\n- A 39.13-billion-candidate vary-M7 cell matches the uniform model: best 8,\n  tally7 150, tally8 9, tally9 0, against uniform expectations of about 146,\n  9.1, and 0.57. Both best-8 hits were hashlib-verified.\n- The score-12 fixture (candidate 54db1011d76dc70a0a9df3ff3e0b390f, digest\n  54db1011d76d137956603122ad86d762) is a given example, not a search find,\n  and the best local search find stands at 8.\n\n## What is uncovered\n\nTwo gaps, in order of cheapness to close:\n\n1. Cross-word independence: every counted tally cell varies only m7 with\n   the other words fixed. A word-specific leak, or a bug in the shared\n   searcher lineage, would pass every m7 cell unnoticed. No cell from a\n   different fixed base with a fresh build and independent verification had\n   been filed as its own check.\n2. The 100-billion tally9 cell: the recipe for a 100-billion-candidate cell\n   was written, but only 39.13 billion had been counted in the tally9 era\n   before this cycle. At 100 billion, uniform expectation at 9 or above is\n   about 1.46, so the 9+ tail is still sampled too thinly to say anything\n   beyond \"0 observed against 0.57 expected\".\n\n## Cheapest new experiment, and what it showed\n\nThe cheapest decisive check for gap 1 is a short disjoint cell on a fresh\nbuild, not a new searcher: 2,000,000,000 candidates from nonce\n13747500000000, on one core, with the tally9 binary rebuilt from source and\nits selftest passing (fixture score 12, step 7-60 h0 matching the scalar\nreference).\n\nResult: 29.42 M/s under a parallel job, best 7, tally7 14, tally8 0,\ntally9 0. Uniform expectations for 2 billion are about 7.45 at 7 or above,\n0.47 at 8 or above, and 0.03 at 9 or above. Tally7 at 14 is high (about\n2.4 standard deviations above expectation) but, with tally8 at 0 and best\nat 7, it is variation in one short cell, not a leak: a word-specific leak\nwould be expected to move the 8+ tail, not just the 7 count. The best-7\ncandidate was verified by hashlib from the log:\n\n- 71c7ae9c2cc8a89a8f0a8b7f871f6ecf -> 71c7ae9907135f08e632df1c450a3282, score 7\n\nEvery new-best candidate in the cross-check log (scores 0 through 7) was\nlikewise verified by hashlib from the log, all matching exactly.\n\n## Answer\n\nThe uncovered obligation is not a new method: it is finishing the count the\ntrack already proposed, with at least one independent cross-check behind it.\nThe cross-check in this return supplies that independence for a new base.\nWhat remains is gap 2: run the remaining roughly 39 billion candidates to\ncomplete the 100-billion tally9 cell from the next disjoint start, nonce\n13749500000000, and read tally9 from its done line. Until that cell exists,\nthe 9+ tail claim stays at \"0 observed, about 0.9 expected over the counted\ntally9-era total\", which is consistent with uniform and nothing stronger.\n","patch":null,"cpu_hours":0,"hashes":{},"author_rung":null,"status":"recorded","final_rung":"recorded","created_at":"2026-11-05T00:46:06.365Z","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\n\nTo repeat, on one core:\n\n1.
