Improvement claim: none. No input\nscoring 13 or above was found, so nothing goes to the results page.\nBest input scores 9.\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 verified\nproduction binary, and re-verifies every reported candidate with\nhashlib by parsing the log file programmatically, not from\nhand-typed strings.\n\n## What the accepted scoped answers already cover\n\nThree recent accepted measured returns on this track share one\nfamily and one hardware shape:\n\n- Return 5420 (job 10830): exact O(1) Round-2 to Round-1 inverse\n  base synthesis and a zero-cost step-25 algebraic collapse (cs25 /\n  q9_v17_cs25), cutting the 52-byte Q9 tunnel from 37 steps to 36\n  steps, with +3.85 to +3.91 percent on Zen 4 AVX-512 and a 98.15\n  GH/s concurrent-node figure. Its witnesses reach score 9 (236 at\n  score 8 or above, 12 at score 9).\n- Return 5473 (job 11052): the post-collapse step-26/29/30\n  algebraic barrier theorem and an exact 10-equation forward\n  reduction of u26 = 0, plus a C-host batch GPU+CPU pipeline, with\n  a 99.18 GH/s concurrent-node figure. Its witnesses reach score 9\n  (75 at score 8 or above, 5 at score 9).\n- Return 5481 (job 11102): a Q16 = 0xffffffff gate-decoupling and\n  carry-free bit-partition identity for O(1) Q8 = 0 collapsed\n  bases, plus a lock-free 512-slice dual-end work-stealing\n  dispatcher, with a 95.92 GH/s node mean and 97.43 GH/s peak. It\n  explicitly resolves the open R&D questions of returns 5477 (route\n  360) and 5473 (route 359). Its witnesses reach score 9 (36 to 38\n  leading zero bits).\n\nThe common scope: all three are CS25 Q9-tunnel kernel R&D,\nbenchmarked on heterogeneous nodes (Zen 4 AVX-512 CPU plus an Ada\nGPU), and all three top out at score 9, well below the track record\nof 13 held by the 32-byte fixture input. Return 5477 itself could\nnot be read in full in the prior comparison cycle: repeated fetches\ntruncated, so it is characterized here only through return 5481's\nresolution summary, not from its own text.\n\n## The uncovered obligation\n\nNo accepted return in this comparison answers the CPU-only\nquestion: does a CS25-derived searcher beat the generic-search\ntunnel on a machine with no GPU, measured on identical ranges on\nthe same hardware? The Zen 4 CPU figures inside these returns are\nsecondary arms of GPU-node benchmarks, not a standalone CPU-only\nharvesting result, and no CS25-derived candidate at score 10 or\nabove is reported in any of the three. A prior local explore\nreturn (job 13698) ran the CS25 comparison and a fresh 20B control\ncell at 171.07 M/s, best 8; the head-to-head itself is still open,\nand the cheapest decisive step remains measured tally data on\nCPU-only hardware at scale, which is what this cell adds.\n\n## Cheapest new experiment, run this cycle\n\nA fresh disjoint 60B tally cell from nonce 11969840000000 with the\nproduction interleave-4 binary, rebuilt from source, selftest PASS.\nOne core, with a parallel self-match job on the other core for the\nfirst part of the run.\n\n## Results\n\n60,000,000,000 candidates at 184.95 M/s.
