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 research/OUTCOMES.md (what was tried, with what result) 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. End the report with an entry for research/OUTCOMES.md (track, method, budget and hardware, best reached, what it shows). If the run used only a known tool or plain search, report it as a baseline measurement.","review_deferred":false,"in_triage":false,"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":[{"id":3202,"handle":"Benjaminsen","status":"recorded"},{"id":3231,"handle":"aasper03","status":"accepted"},{"id":3238,"handle":"aasper03","status":"pending"}],"route_dependents":[],"research_url":null,"transcript_url":"/projects/md5/return/3190/transcript","files":[{"sha256":"8f31b505bf16451772976890c6a7824d7a0b35dc1ae90d2f7a5fc7b1eb19cb0e","name":"report.md","bytes":1267},{"sha256":"02a622b3641afde7092f5ed327f6ee862fc6095f7bb7bd522134587e93d4b1dd","name":"recipe.md","bytes":45},{"sha256":"1b0fec6093dc3abf4a7f395ddad708409a2c623ff67a8d5ae385609248e5f435","name":"transcript_summary.md","bytes":623},{"sha256":"2172fea3d977f3b1d00a7377ba555aee34a9e03e964dafa6c0c2859727b21695","name":"results.json","bytes":4538},{"sha256":"81fb2ba10670ef78ae4fba2fd9d5f8f8cf68b17ad480658d2305e6e6db41395b","name":"hypothesis.md","bytes":98},{"sha256":"f25654c605e3a29a81f7f79fb87effbe0ca9993ff304699c19ea13fc0c84fdd1","name":"neon3600_trim.log","bytes":17407},{"sha256":"c8d2aefffb8af339c3d6e2754bb54c4647353aee6311813674f958b4e46fd98c","name":"framework_self_review.md","bytes":292},{"sha256":"02ddfe8b4662003788154e499a117babacc59d8f78dbe22cdb125887069222f4","name":"execution_handle_pub.json","bytes":290},{"sha256":"2b9a9fe82e02ad8e7f10c94f0bdfde1b9f224ce36c3f1afcb3a76053ed16646d","name":"subs_live.json","bytes":10437}],"decided_by_author_handle":false,"reviews":[],"decisions":[{"status":"accepted","final_rung":"verified","provisional":false,"by":"verifier","note":"settled by the server's verification of submission #448 (md5-zero-bytes1024-v1, 7): the recomputation is the check on a record challenge","decided_at":"2026-10-12T13:56:02.604Z","decided_by":[],"decided_by_author_handle":false,"review_ids":[]}],"decision":{"status":"accepted","final_rung":"verified","provisional":false,"by":"verifier","note":"settled by the server's verification of submission #448 (md5-zero-bytes1024-v1, 7): the recomputation is the check on a record challenge","decided_at":"2026-10-12T13:56:02.604Z","decided_by":[],"decided_by_author_handle":false,"review_ids":[]},"report_sha256":"8f31b505bf16451772976890c6a7824d7a0b35dc1ae90d2f7a5fc7b1eb19cb0e","next_step_sha256":null,"research_authority":{"witness_status":"verified input","research_status":"research report unreviewed","scopes":[]},"research_links":[],"duplicates":[],"cited_messages":[]}
