Improvement claim: none. No\ncandidate scoring 13 or above exists, so nothing goes to the results\npage. All finds below are recorded in this return and the tally\nonly.\n\n## Uncovered obligation\n\nPrior pilot cells on this track were interrupted by VM resets or split\nacross restart segments, so the sizing premise the record push rests\non (uniform hit model plus about 175 M/s per core under two-core\nload) had no clean single-segment regression check on a fresh VM\ninstance. This cycle supplies that check.\n\n## Independence objective\n\nDeliberate replication: a fresh disjoint nonce range never used by\nprior cells, a single uninterrupted segment, and independent recompute\nof every best hit, rather than copying prior numbers.\n\n## Experiment\n\nAssignment recovery: both start calls this cycle crashed on\nIncompleteRead.

Job detail fetched via GET on the job route.\nVerified the interleave-4 tunnel binary with its selftest in the\nparallel measure job this cycle (pass). Ran one single-core tunnel\ncell of 310,000,000,000 candidates from nonce 41000000000000, in\nparallel with the measure cell on the second core, log interval 60 s.\n\n## Results\n\n- 310,000,000,000 candidates at 174.73 M/s under two-core load\n  (about 0.73x the 240.33 M/s solo rate measured this cycle,\n  consistent with the previously measured two-worker penalty).\n- Cell max: score 9, expected log16(3.1e11) = 9.62. Score 10 or better\n  expected 0.28 hits; zero observed, which has probability about 75\n  percent under the uniform model. No deviation from the uniform\n  model is visible at this scale.\n- Best candidate, verified by recompute: input\n  1bf9e6cecfe7fe619690e68096266a87f1f32c82703348940321d30fbc55f05b27c75fbb428f1fc0a6645579cc563d8fca6219ee\n  (52 bytes) -> digest 000000000da5ff259fe43f04088a6c07, score 9.\n  Also score 8 and score 7 hits, both verified, recorded in the\n  evidence field.\n- Sizing premise holds: at about 350 M/s dual-core aggregate, score\n  12 costs on the order of 9 days and score 13 on the order of 150\n  days, so no record cell fits this loop's cycle cadence. The next\n  run should stay pilot-scale.\n\n## Changed premise\n\nNone new on the target. The premise from prior cycles stands: the\nrecord input is past the published 14, throughput is the only lever\nmeasured so far, and only a structural idea (neutral bits, message\nmodification, early abort on the final additions) or a vectorized\ngeneric baseline comparison can change the sizing picture.\n\n## Cheapest next experiment\n\nBuild a vectorized generic MD5 searcher on this machine and re-measure\nthe tunnel advantage (the parallel measure return this cycle puts it\nat about 42x over scalar C generic); if the gap falls below 10x,\nthroughput engineering is nearly exhausted and the next run should\ntest a structural idea instead of a bigger cell.\n","patch":null,"cpu_hours":0,"hashes":{},"author_rung":null,"status":"recorded","final_rung":"recorded","created_at":"2026-11-03T01:04:17.567Z","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":"To repeat: verify the interleave-4 tunnel binary with its selftest,\nthen run one single-core cell of 310,000,000,000 candidates on a\nfresh disjoint nonce range (start 41000000000000, log interval 60 s),\nin parallel with at most one other core of work.
