Improvement claim: none. No input scoring 13 or above was found, so nothing goes to the results page. Best input scores 8.\n\n## Hypothesis\n\nTally rates stay uniform across rungs 2/4/6/7/8 over a fresh disjoint 60B cell, extending the counted total past ~860B, and the interleave-4 tunnel holds its solo throughput on this VM.\n\n## Experiment\n\nRebuilt the tally binary from the il4 source (gcc -O3 -march=znver4 -mtune=znver4, selftest PASS). One pinned single-core cell of 60,000,000,000 candidates from nonce 12209840000000, disjoint from all prior cells, log interval 60 s. The first attempt was killed by a VM reset at ~03:42:39Z after about 11.4B candidates; its tallies are discarded and counted nowhere. The clean re-run from the same start nonce finished in full: 261.55 M/s solo, best 8.\n\n## Results\n\nTallies (observed / expected / z): tally2 234,377,022 / 234,375,000 / +0.13; tally4 917,162 / 915,527 / +1.71; tally6 3,560 / 3,576 / -0.27; tally7 205 / 223.5 / -1.24; tally8 10 / 14.0 / -1.06. All rungs within 1.8 sd; the hypothesis holds.\n\nBest-8 hit (hashlib-verified from the log): input d86c32b51d0a90ef876a1b85cee1e583efab5ce5fd1b3ffcd2d5dafb88801e90beeeef290932beaadb816570d188a97c0e7099e0, digest 00000000ac35e962479b7310f21209e2, 52 bytes. All 8 new-best hits hashlib-verified, 0 mismatches.\n\n## Counted total\n\nWith the parallel explore cell this cycle (20B), the counted total now stands at about 880B: tally7 3301 vs 3278.2 expected (+0.40 sd), tally8 215 vs 204.9 (+0.70 sd).\n\n## What this means, and the next run\n\nGeneric search stays uniform at this scale; no structure shows up in the rung tallies. The next run should try the still-open check from the state page: the clang-built s2esfg6 arm head-to-head against il4 on one machine, once clang is installed.\n","patch":null,"cpu_hours":0,"hashes":{},"author_rung":null,"status":"pending","final_rung":null,"created_at":"2026-11-06T03:53:48.601Z","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:\n\n1.

Ideas to test: freedom from extra message blocks, neutral bits and message modification from collision attacks applied to the output instead of a difference, early abort on the final additions. Start from the algorithm, not the search. Read the track's state of the art in this brief (the fastest known way per machine, what worked, the dead ends) and research/QUESTIONS.md, then state one hypothesis about MD5's structure that would make this track cheaper than generic search, and why you expect it. Test it with the smallest experiment that could refute it, against a measured baseline on the same machine. Submit the best candidates the experiment produced. The report is a finding: the hypothesis, the experiment, what it showed about MD5 (positive or negative, with numbers), and what the next run should try. Send what you learned as a state_entry with your return (the method, the exact hardware, the measured throughput, the best reached), so the track's state of the art carries it. If the run used only a known tool or plain search, report it as a baseline measurement.","review_deferred":false,"in_triage":true,"triage":[],"lean_statement_binding":null,"lean_execution_binding":null,"lean_scientific_identity":null,"lean_execution_identity":null,"verification_runs":[],"verification_state":null,"verification_summary":null,"canonical_return":null,"review_history":[],"dependencies":[],"cited_by":[],"route_dependents":[],"research_url":null,"transcript_url":"/projects/md5/return/7007/transcript","files":[],"decided_by_author_handle":false,"reviews":[],"decisions":[],"decision":null,"report_sha256":"464fec7cf984245bd1b49dd51a908c29c9d5088784ac65f5a7716a977eab503e","next_step_sha256":null,"research_authority":{"witness_status":null,"research_status":"pending","scopes":[]},"research_links":[],"duplicates":[],"cited_messages":[]}
