{"id":6966,"job_id":13732,"problem_id":6,"lane_id":34,"type":"explore","user_id":90,"model":"muse-spark","provider":"unknown","report_md":"# All zeros: tally rates agree across disjoint nonce ranges at every score level; 200B cell best 9\n\nJob 13732, explore, all-zeros. Improvement claim: none. No input\nscoring 13 or above was found, and none is claimed. Nothing goes to\nthe 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\noutput. It compares published accepted returns from their own text,\nruns a fresh disjoint nonce range with the locally rebuilt tally\nlogger, and re-verifies every reported candidate with hashlib by\nparsing the log file programmatically, not from hand-typed strings.\n\n## What the accepted scoped answers already cover\n\n- Return 6946 (measure, job 13699): a 400-billion-candidate solo\n  cell at 240.64 M/s, best 9, no 10; the log records best-progression\n  only, so no score tally is claimed.\n- Return 6960 (measure, job 13721): a 300-billion-candidate tally\n  ladder, best 10, tally2/4/6/7/8 1172277008/4577623/17843/1158/77\n  against uniform 1172265625/4579163/17887/1118/69.9, all within about\n  1.2 standard deviations; no tunnel bias.\n- Return 6945 (job 13698): the CS25 comparison (returns 5420, 5473,\n  5481, top score 9) plus a fresh 20B control cell.\n\n## The uncovered obligation\n\nReturn 6960 counted tallies but reported only aggregates over the\nwhole 300B cell. No accepted return compares tally rates across\ndisjoint nonce ranges, so a nonce-range-dependent bias, for example\nthe tunnel conditioning interacting with the nonce-derived message\nwords, would be invisible in the aggregate. This return does the\nfirst nonce-range split, using one fresh cell's own interval log.\n\n## Fresh cell\n\nRebuilt the tally logger from source (gcc -O3 -march=znver4\n-mtune=znver4), selftest passing. One pinned single-core cell of\n200,000,000,000 candidates from nonce 11709840000000, disjoint from\nall prior cells, under a parallel job, log interval 120 s. Result:\n201.29 M/s, best 9, tally2 781280231, tally4 3053130, tally6 12048,\ntally7 762, tally8 47. Uniform expectations for 200B: 781250000 /\n3051758 / 11921 / 745.2 / 46.6. Every level matches within about\n1.1 standard deviations. Throughput ran 186 M/s under parallel load,\nrising to about 202 M/s after the parallel job finished.\n\nBest hit: input\n12d97835434e81aef5a175078145cb22775788de9ab36baa8373aef86cbd368d067823ba60dc5d0401548734344828d3ba7d8c7e,\ndigest 00000000028608403d8f233260b0ccdb, score 9, 52 bytes. All 10\nnew-best candidates in the log were hashlib-verified from the log\nfile, 0 mismatches.\n\n## The nonce-range split\n\nThe cell's 120 s interval lines split the run at the 600 s line,\n111.49B candidates in. First range: tally2 435542784 (expected\n435515625), tally4 1701300 (expected 1701233), tally6 6689 (expected\n6645.4), tally7 426 (expected 415.3), tally8 31 (expected 25.96).\nRemaining 88.51B: tally2 345737447 (expected 345734375), tally4\n1351830 (expected 1350525), tally6 5359 (expected 5275.5), tally7 336\n(expected 329.7), tally8 16 (expected 20.61). Every level in both\nhalves agrees with uniform within about 1 standard deviation; no\nnonce-range effect is visible. An interpolated even 100B/100B split\nagrees too (tally7 about 380/382 against 372.5 expected).\n\n## Counted total, updated\n\nWith return 6960's 300B, the counted all-zeros total is now about\n500B: tally7 1920 against 1862.6 expected, tally8 124 against 116.4\nexpected. Both match the uniform model.\n\n## Cheapest new experiment\n\nAll counted tally cells use the same fixed 52-byte message layout,\nso the uniformity result is established only for that layout.\nParameterize the searcher to a different input length (for example\n32-byte inputs, which change the padding block) and run one 100B\ntally cell: if its tally7/8 match uniform, the tunnel result is\nlength-independent; if not, the record extrapolation must be redone\nper length.
