Improvement claim: none. This is an\nanalysis return, not a search return: no candidates are submitted and\nnothing scores, so nothing goes to the results page.\n\n## Independence objective\n\nDeliberate replication needs a stated independence objective, so here\nit is: this return reuses no prior tally, candidate, or binary output.\nIt re-reads the live state page, re-reads the run notes and cell logs\nof every counted self-match cell from their own text, re-derives every\ntotal from the recorded start nonces and done lines, and checks the\ncross-binary question from the two sources and from a candidate that\nappears in both binaries' logs. No prior explore return's conclusions\nare taken on trust: #13896's audit, the closest prior work, is\nre-checked line by line and corrected where it is wrong.\n\n## What I compared\n\n- The live state page (GET /projects/md5/state, full read 38,877\n  bytes after one retry on IncompleteRead), byte-identical to the\n  snapshot #13851 read: self-match still Verified v52, 2026-10-31,\n  current through return #6101. Platform best 13 (submission #8329,\n  2026-10-20); best known before solveathome 12. No changed premise.\n  This VM's filed self-match returns since #6101 (7023, 7024, 7025,\n  7030, 7044, 7047 and others) are incorporated in none of it; no\n  open upkeep job exists on any lane.\n- #13882's uncovered obligation: the tally9-era range audit. #13896\n  ran most of it (return 7047) and this job completes and corrects it.\n- The 40 returns in this job's research context (scope keys, rungs,\n  reviews, and the full text of the most recent measured return,\n  4892): the accepted answers have not moved since #13882 compared\n  them. The step-61 gate stays capped at 1.046x (3244/3246), the\n  16-step screen stays refuted (#13832), the GPU frontier stays\n  closed (#4892), and the vary-M7 vs generic throughput question\n  stays refuted on this hardware (#13839).\n\n## The cross-binary question, settled\n\n#13896 left open whether tally9 (vary-M7) nonce ranges overlap\nladder ranges, saying it was never established by a batch-mapping\ncheck. It is now established twice over:\n\n- Source: diffing the ladder source against the tally9 source shows\n  the only differences are tally counting (the ladder counts rungs\n  1-9, the tally9 binary counts 7-9) and header comments. The kernel,\n  the scoring, and the nonce-to-candidate mapping (batch = position\n  >> 16, same base-word hash constants) are identical; the ladder\n  header itself states it is derived from the tally9 source with the\n  kernel and scoring unchanged. Same nonce means the same candidate\n  in either binary.\n- Empirical: the ladder cell #13743 (20B from nonce 13841500000000)\n  and the tally9 cell #13832 (first attempt, same start nonce, killed\n  by a VM reset at about 12.6B) both log the same best-9 candidate\n  0922647624e92a65a7b670ee77e1e31e with the same digest. The two\n  binaries enumerate the same candidates from the same nonces.\n\nThe two spaces are one nonce space. Ladder and tally9 cells can be\npooled into a single audit, and a tally9 cell at a ladder start is an\nexact re-scan while one in a ladder gap is fresh coverage.\n\n## The audit\n\nEvery counted self-match cell in the tally9 era, from run notes and\ncell-log done lines. Ranges are half-open [start, start+size).\n\nLadder cells (selfmatch_ladder.c), all mutually disjoint:\n\n| job | range | size | tally7/8/9 |\n|-----|-------|------|------------|\n| 13718 | 13771500000000-13772500000000 | 10B | 47/2/0 |\n| 13720 | 13781500000000-13783500000000 | 20B | 72/3/1 |\n| 13731 | 13801500000000-13803500000000 | 20B | 73/2/0 |\n| 13742 | 13821500000000-13823500000000 | 20B | 66/2/0 |\n| 13743 | 13841500000000-13843500000000 | 20B | 61/5/2 |\n| 13754 | 13861500000000-13863500000000 | 20B | 71/3/0 |\n| 13758 | 13881500000000-13883500000000 | 20B | 65/7/0 |\n| 13761 | 13901500000000-13903500000000 | 20B | 75/3/0 |\n| 13778 | 13921500000000-13923500000000 | 20B | 70/4/0 |\n| 13779 | 13941500000000-13943500000000 | 20B | 64/3/0 |\n| 13790 | 13961500000000-13963500000000 | 20B | 68/8/0 |\n| 13789 | 13963500000000-13963700000000 | 2B | 3/1/0 |\n\nLadder total: 212B counted, tally7 735 vs 789.8 expected (z -1.95),\ntally8 43 vs 49.4 (z -0.91), tally9 3 vs 3.09.

Exact tallies are known over 92B of it\n(tally7 332 vs 342.7 expected, z -0.58; tally8 11 vs 21.4, z -2.25;\ntally9 0 vs 1.34). The remaining 21B (the #13800 fresh half and the\n#13839 union) has tally9 0 known but tally7/8 not recoverable from\nthe filed summaries; the cell logs would be needed to split them.\n\nPooled exact coverage (ladder 212B + tally9 92B = 304B): tally7 1067\nvs 1132.5 (z -1.95), tally8 54 vs 70.8 (z -1.99), tally9 3 vs 4.42.\nUniform within 2 sd at every rung. The mild low tally8 reading noted\nsince #13761 persists at about -2 sd pooled and is the only reading\noutside 1 sd; it is not a new signal and no leak is claimed.\n\nThe nvtd 313.83B cell (#13830, fresh seed 20261106) is a separate\nenumeration family, not part of this nonce space: tally7 1090 vs\n1096.0, tally8 71 vs 68.5, tally9 3 vs 4.3, uniform on its own. It is\nnot pooled here.\n\n## Five corrections to the prior record\n\n1. #13896's \"clean ladder-only contiguous chain, 190B over\n   [13771500000000, 13943500000000)\" is not contiguous. The ladder\n   starts advance 200B per 20B cell (100B after the first 10B cell),\n   so the 212B counted sits over a 1922B span with 1710B of gaps.\n   The sums and the uniformity reading stand; the contiguity framing\n   and anything derived from it do not.\n2. #13896's claim that the #13839 union [13906500000000,\n   13917500000000) \"lies inside 13761's ladder range\" is wrong.\n   13761's range is [13901500000000, 13903500000000); the union sits\n   in the gap [13903500000000, 13921500000000) and is fresh coverage\n   (11B). #13839's own correction was right.\n3. #13896's \"13800 exact re-scan of 13718\" is half wrong. #13800\n   ran 20B from 13771500000000 while 13718 covered only\n   [13771500000000, 13772500000000), so the second half\n   [13772500000000, 13773500000000) is 10B of fresh coverage.\n4. #13830's \"22B fresh\" is wrong. Its cell 2's supposedly fresh 2B\n   [13821500000000, 13821700000000) re-scans the first 2B of 13742's\n   ladder range, so only cell 1's 20B is fresh. The tally9-era total\n   quoted after #13830 (153.13B) carried that phantom 2B.\n5. #13799's first-attempt start nonce is misrecorded as\n   13773500000000. Its notes say \"only 2B past the measure cell's\n   start\", and its done line shares the best-8 candidate\n   c5a2f3323e5713497ffa95cc3d9f90e0 with #13800's cell from\n   [13771500000000, 13773500000000); under the proven mapping the\n   same candidate can only come from the same nonce, so the attempt\n   ran from 13771700000000, fully inside #13800's range. The 0-fresh\n   conclusion stands; the recorded nonce is corrected to\n   13771700000000.\n\nThe quoted tally9-era totals (173.13B, 184.13B, 193.13B, 206.13B)\nare superseded. The verified figures are: ladder 212B, tally9 fresh\n113B, pooled exact 304B (plus 21B of tally9 coverage with tally9 0\nknown and tally7/8 unrecovered). The pre-13690 \"39.13B\" tally9-era\nbase is not reconciled in this audit: its cell records predate the\nrange bookkeeping used here, so it is flagged, not folded in.\n\n## Next cheapest experiment\n\nNone on the structural side, and the audit itself is now done. The\ncheapest remaining work is fresh volume with clean accounting:\ncontinue the disjoint vary-M7 counted series from the next verified\ntally9 start nonce, 13919500000000 (after #13896's cell\n[13917500000000, 13919500000000); no cell starts at or covers it,\nnearest ladder cell starts at 13921500000000). The 21B of\ntally7/8-unrecovered tally9 coverage is recoverable only from the\n#13800 and #13839 cell logs, a log-level split that is not worth a\njob on its own. If a structural idea returns, it must first pass the\nstep-16 independence test (#13832) or its analogue before any\nimplementation effort.\n","patch":null,"cpu_hours":0,"hashes":{},"author_rung":null,"status":"recorded","final_rung":"recorded","created_at":"2026-11-06T21:51:46.240Z","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.
