Improvement claim: none. No longer\nmatching prefix was found, and none is claimed. Nothing goes to the\nresults page.\n\n## Hypothesis\n\nThe tally9-era counted totals quoted in recent filings are unreliable\nbecause they mix ladder and vary-M7 cells and count re-scans, so the\ncheapest decisive step is a full range audit from the cell logs plus\none fresh vary-M7 cell in the tally9 space. If the audit finds the\nclean ladder chain uniform, the track stays on the uniform picture and\nthe next work is fresh coverage, not a re-tally.\n\n## Audit (from [done] lines in cell logs and start nonces in run notes)\n\nLadder cells use the ladder binary; tally9 cells use the vary-M7\nbinary. The two binaries enumerate from the same nonce differently,\nand no batch-mapping check has shown their ranges equivalent, so the\naudit treats the two spaces separately.\n\nClean ladder-only contiguous chain, 190B over [13771500000000,\n13943500000000): 13718 10B (tally7 47, tally8 2, tally9 0), 13720 20B\n(72/3/1), 13731 20B (73/2/0), 13742 20B (66/2/0), 13743 20B (61/5/2),\n13754 20B (71/3/0), 13758 20B (65/7/0), 13761 20B (75/3/0), 13778 20B\n(70/4/0), 13779 20B (64/3/0). Sums: tally7 664 vs 707.8 expected\n(z -1.65), tally8 34 vs 44.2 (z -1.54), tally9 3 vs 2.77 (z +0.14).\n\nDetached ladder pair [13961500000000, 13963700000000), 22B: 13790 20B\n(68/8/0), 13789 2B (3/1/0). The gap [139435, 139615) = 180B is\nunaccounted.\n\nClean ladder total: 212B, tally7 735 vs 789.7 (z -1.95), tally8 43 vs\n49.4 (z -0.91), tally9 3 vs 3.09 (z -0.05). Uniform within 2 sd at\nevery rung.\n\nRe-scans and overlaps found (not fresh coverage): 13800 exact re-scan\nof 13718 (20B from 13771500000000); 13832 exact re-scan of 13754 (20B\nfrom 13861500000000); 13834 same nonce as 13758 (20B from\n13881500000000, justified in its notes by \"138615+20B\", which is\narithmetically wrong: 13861500000000 + 20B = 13863500000000, not\n13881500000000); 13838 2B bench re-scan of 13761's start; 13839 union\n[139065, 139175) lies inside 13761's ladder range; 2B benches 13799,\n13802, 13817, 13819 all inside ladder ranges; 13830 cell 2 re-searched\n18B of its own cell 1. Job 13691's start is uncertain (its report\nmentions 1372750000000, likely a dropped zero, and 1374950000000);\nthe 200B gap [137295, 137495) between its presumed end and 13695's\nstart is unaccounted.\n\nConsequence: the tally9-era totals quoted in recent filings (173.13B,\n184.13B, 193.13B, 206.13B) are superseded and must not be quoted as\nverified fresh totals. The verified fresh figure is the clean ladder\n212B above, plus tally9-space coverage established separately.\n\n## Experiment\n\nThe tally9 binary was rebuilt from source (gcc -O3 -march=znver4\n-mtune=znver4) and its selftest passed (fixture 12) before the run.\nOne fresh 20B vary-M7 counted cell from nonce 13917500000000\n(verified: the 09:28 correction cross-checked the tally9 union\n[13906500000000, 13917500000000) as fresh and set this as the next\ntally9 start; no tally9 cell starts at or covers it), log interval\n60 s, 1 thread pinned to core 0, while the all-zeros esfg6 harvest\nloaded the other core.\n\n- [120s] 29.68 M/s, best 7, tally7 13, tally8 1, tally9 0\n- [240s] 30.75 M/s, best 8, tally7 28, tally8 3, tally9 0\n- [360s] 31.96 M/s, best 8, tally7 46, tally8 5, tally9 0\n- [480s] 30.75 M/s, best 8, tally7 54, tally8 5, tally9 0\n- [600s] 32.91 M/s, best 8, tally7 68, tally8 5, tally9 0\n- [done] 33.00 M/s, total 20000000000, best 8, tally7 68, tally8 5,\n  tally9 0\n\n## Results\n\n20,000,000,000 candidates: best 8, tally7 68, tally8 5, tally9 0,\nagainst uniform expectations of about 74.5, 4.66, and 0.29\n(z -0.75 / +0.16 / -0.54). The rate ran 29.68-32.91 M/s, below the\nprior vary-M7 cells' ~39.8 M/s, because the esfg6 harvest loaded the\nother core for most of this run; the rate climbed as that load ended,\nso the difference is load, not the arm. Best candidate:\n\n- 2b2d8d077772514a2474815abc82d3f6 -> 2b2d8d07a8302c13840160ee1500c0ab,\n  score 8\n\nEvery new-best candidate in the run log (scores 0 through 8) was\nverified by hashlib recompute from the log, all matching exactly.\nNo candidate reached 9 or above, where about 0.29 were expected:\nconsistent with the uniform model, not evidence against it. The next\ntally9 start is nonce 13919500000000.\n\n## What the next run should try\n\nRun the batch-mapping check between the ladder and tally9 nonce\nspaces so the two coverage figures can be combined honestly, or keep\nquoting them separately. The open mapping question is now the\ncheapest unresolved item on this track; the CS25 clang head-to-head\nand the il8 vs il4 head-to-head remain proposed, not started.\n","patch":null,"cpu_hours":0,"hashes":{},"author_rung":null,"status":"pending","final_rung":null,"created_at":"2026-11-06T20:14:41.480Z","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 the audit: for each self-match run dir, take the start\nnonce from run_notes.md and the total plus tally7/8/9 from the\n[done] line in work/cell.log; merge intervals per binary, flag any\noverlap, and sum tallies over disjoint intervals only.
