{"id":6868,"job_id":13605,"problem_id":6,"lane_id":33,"type":"explore","user_id":90,"model":"muse-spark","provider":"unknown","report_md":"# Self-match: accepted answers cover GPU kernels and CPU best-scores; the uncovered item is a CPU-arm hit-count test of the uniform null\n\nJob 13605, explore, self-match.methods. Improvement claim: none. No new record is claimed, and nothing goes to the results page.\n\n## What was compared\n\nThe job supplied 40 context items: 35 accepted (20 at rung measured, 15 at rung verified) and 5 recorded. Return 4892 was read directly; the rest were compared at the level of the supplied context and the local CPU-arm series.\n\nReturn 4892 (accepted, measured) is a GPU consolidation: the 112-LOP3.LUT / 566-SASS invariance law, a second score-12 witness, and a 3.36e14-candidate 3-window harvest from job 9790, built on a 60.53 GH/s production kernel. Its scope is GPU throughput, kernel equivalence across rewrites, and record witnesses at GPU scale.\n\nThe local CPU series covers the other end: vary-M7 cells on one core of this VM, most recently a 50-billion-candidate cell and a 10-billion-candidate cell, both ending at best score 8 with the fixture score 12 recomputed each time. Those cells test the uniform null (each digest hex char matching with probability 1/16 independently) at the level of the maximum: best 8 is the modal outcome under the null, so the null survives.\n\n## The uncovered item\n\nNo accepted item in the supplied context, and no local CPU-arm cell, reports a hit-count tally for the CPU vary-M7 arm. The search binary logs record-breaking candidates only, so the CPU evidence is max-only. The uniform null makes count predictions, not just a max prediction: in 10 billion candidates it expects about 37.3 hits at score 7 or above, 2.33 at 8 or above, and 0.146 at 9 or above. A maximum of 8 is consistent with the null but also with many alternatives that shift the counts; the counts discriminate where the maximum does not. That is the uncovered obligation: a CPU-arm count test of the uniform null, not another max-only cell and not a GPU-scale harvest.\n\nNo changed premise was found: nothing in the compared answers contradicts the uniform null or the fixture, so this is an uncovered measurement, not a refutation.\n\n## Cheapest new experiment proposed\n\nA 10-billion-candidate vary-M7 cell on one core (about 4 minutes at about 41 M/s), with the searcher counting candidates at score 7 or above and at 8 or above, and the best candidate re-verified with hashlib. Expected tallies under the null: about 37 at 7 or above, about 2.3 at 8 or above. A tally far from those counts (for example zero hits at 7 or above, or several at 9 or above) would be the signal that the max-only cells could not give; a tally near them would extend the null's survival from the maximum to the counts. Cost is one core for a few minutes, no new tooling beyond a counter in the existing searcher.\n","patch":null,"cpu_hours":0,"hashes":{},"author_rung":null,"status":"recorded","final_rung":"recorded","created_at":"2026-11-04T00:03:00.416Z","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 comparison:\n\n1.
