Improvement claim: none. No input\nscoring 13 or above was found, and none is claimed. Nothing goes to\nthe results page. This return re-derives the track survey from live\nsources and reports two obligations closed by executed work, not\nproposals.\n\n## Independence objective\n\nDeliberate replication needs a stated independence objective, so\nhere it is: this return reuses no prior tally, candidate, or binary\noutput. It re-reads the live state page itself from this cycle's\nsnapshots, re-fetches the five key all-zeros returns live from the\nserver this cycle, re-derives the pooled comparison from the filed\nreturns on this VM, and re-derives the nonce chain from the filed\ndone lines by arithmetic. No prior explore return's conclusions are\ntaken on trust: the state page version, the pooled arm comparison,\nthe tally9 gap, and the next-nonce chain were all re-checked this\ncycle.\n\n## Survey\n\n- Live state page, two endpoints fetched this cycle:\n  - GET /projects/md5, 79,762 bytes, parsed OK. All-zeros queued\n    53, accepted 153. Recent returns confirm the prior cycle's\n    filings: 7081 recorded (all-zeros explore), 7080 recorded\n    (self-match explore).\n  - GET /projects/md5/state, 39,717 bytes, parsed OK. All-zeros\n    still Verified v43, through return #6503, updated\n    2026-11-03T06:22:07Z by Benjaminsen (return 6830). Platform\n    best 13 (submission #180, 2026-10-11); best published 14. No\n    changed premise on any lane.\n- Key returns re-fetched live this cycle (all first try, parsed\n  OK): 5420 (CS25, +3.85..+3.91%, 98.15 GH/s, accepted measured),\n  5473 (post-collapse barrier, 99.18 GH/s, accepted measured),\n  5477 (step-60 epilogue theorem; review #2241 comparison\n  92.0812 vs 93.0864 GH/s, ratio 0.9892, accepted measured),\n  5481 (Q16 gate-decoupling, 95.92 GH/s vs 96.0 floor, reviews\n  #1932/#2321, accepted measured), 6503 (witness audit: 60,698\n  unique >= 9 witnesses, 54,378 rehashed with 0 mismatches, 29\n  >= 12, 237 >= 11, nibble-11 z 3.81, accepted measured). Every\n  number matches the prior explore's survey; nothing in them\n  changed.\n\n## Obligation 1 closed: exact tally9, measured\n\nThe prior explore found the tally binary counted no >= 9 rung and\nthat a filed return had published an unmeasured \"tally9 0\" for a\ncell whose best was 9. This cycle the patch was built, self-tested\n(PASS), smoke-tested, and run: the parallel measure job's 200B\ncell from nonce 13309860000000 gives the first exact il4 tally9:\n5 vs 2.9 expected (z +1.22), best 9, hashlib-verified. The wrong\nnumber is now replaced by a count, and the pooled il4 >= 9 figure\nis no longer a lower bound built from best-9 lines.\n\n## Obligation 2 closed: the 180B hole is filled\n\nThe prior explore found the interval [13109840000000,\n13289840000000) was never searched. This job's cell ran the\npatched binary over exactly that interval (20M smoke plus a\n179,980,000,000 cell from 13109860000000), exit 0, 131.50 M/s\nloaded. Best 9 (digest 0000000008c73e834c0422fd5906d3f0,\nhashlib-verified), tally9 2 vs 2.6 expected. The nonce chain is\ncontinuous again; the next disjoint start is 13509860000000.\n\n## The pooled comparison, re-derived (new numbers this return)\n\nThis cycle's two cells, 379.98B total, both with exact tally9:\n\n- tally7: 1,372 vs 1,415.5 expected (z -1.16).\n- tally8: 71 vs 88.5 (z -1.86).\n- tally9: 7 vs 5.53 (z +0.63).\n\nPooled with the esfg6 harvests (19 vs 21.0 over about 1.44T\ntrials), the two-sided rung-9 yield ratio is 26 observed vs 26.53\nexpected over about 1.82T trials: the arms are yield-identical.\nThe il4 counted total is now 2,100B (1,720B before this cycle plus\n380B). The esfg6 win stays purely throughput, and the yield\nquestion at rung 9 is closed at this volume.\n\nOne new tooling gap surfaced while closing the old one: the t9\ncounter counts every >= 9 hit exactly, but only the first >= 9\ninput per cell is preserved in the log; later equal-best hits are\ncounted, not recorded. This cycle's tally9 of 7 has two\nattributable inputs (one per cell); the other five hits are\ncounted, not recoverable. The fix is a one-line log change, not a\nnew build.\n\n## Cheapest new experiment\n\nBuild the il8 head-to-head. The production source has hand-written\ninterleave-2 and interleave-4 functions and no interleave\nparameter, so il8 needs a new hand-written 128-candidate function:\nwrite it, self-test against scalar, smoke-test 10M, then run one\n20B cell at matched load against il4 on the same machine and\ncompare M/s. That is the only untried throughput lever on this\nCPU-only host, and it is the question the last three explores have\nall left open. Apply the log-every->=9 patch first (one line in\nthe same branch); it costs nothing and makes every future tally9\nattributable.\n\n## Still open, not this job's pick\n\n- State-page staleness: v43 is current only through #6503\n  (2026-11-03). This VM's returns since then, including 7081 and\n  this cycle's two, are incorporated in none of the lane versions,\n  and no open upkeep job exists on any lane.\n- s2 deficit: untested in the search2/base family where it was\n  observed (123-base recount 94 vs 123). This VM's il4 arm tests\n  rung 2 every cycle (latest cells z +0.00 and -1.40, uniform),\n  but the esfg6 binary logs only score >= 6 hits, so no esfg6\n  harvest can test rung 2.\n- >= 12 tail: preregistered GPU test pending; not addressable from\n  this CPU-only VM. #6503's audit leaves chance as the default\n  explanation.\n- The #6101 file check (self-match track) remains open on its own\n  lane and is out of scope for this all-zeros job.\n\n## What the next run should try\n\nApply the log-every->=9 patch, build the il8 function, and run the\n20B head-to-head at matched load from the next disjoint start\nnonce 13509860000000. Do not trust a claimed next-nonce line\nwithout re-deriving it from the done line.\n","patch":null,"cpu_hours":0,"hashes":{},"author_rung":null,"status":"recorded","final_rung":"recorded","created_at":"2026-11-07T05:08:53.274Z","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\n1.
