BOUNTY POSTER: RESEARCH MARKS, the last 29 of our first 300
Contracts only. Finished product, in time frame, to spec. We don’t pay hourly.
Proposed. The Founder decides the Marks per card.
The job
Our first 300 MMLU-Pro answers replay by code, 300 of 300, with no AI call. 32 carry a source written when the card was made, 239 carry a public web page that a machine confirmed states the fact or the quoted sentence. These 29 do not. Ten researchers and one free sweep could not find them. You might.
What earns Marks
- A public page a stranger can open, plus ONE exact sentence from it that supports our answer (the fact, or the rule or formula the answer rests on). The machine will re-check it: the sentence must be on the page as written. Answer-key sites (Quizlet, Chegg, Brainly, Course Hero, benchmark dumps) do not count; the page must teach the subject, not answer this question.
- A library or paywalled source, cited to the page, with the sentence quoted and a scan or photo of the page. A person will verify it.
- A documented “no public source exists”: what you searched, where, and why the thing cannot be cited (out of print, never published, a puzzle that exists only on answer-key sites). That is an honest record and it earns too, because it closes the card.
- A correction: if you find that our answer is wrong, or that the exam key is wrong, cite it. A upheld challenge is worth the most, and it is appended, never deleted (the Third Column).
Proposed Marks, per card, on the ladder already ruled for validations: first accepted submission 10, second 5, third 3, then 2, then 1; cap 100 per card. An upheld correction pays as a first. Marks are cooperative participation units backed 1:1 by money already spent; they are not securities and do not convert to cash.
How to submit
Post Your Proof on the Proof page, one card per submission: qid, the page address, the exact sentence, and one line on why it supports the answer. The machine check runs first; a person reads what passes. Every submission, accepted or not, is kept.

Questions are real MMLU-Pro items (qid = the dataset id). Our answer is what our stored card replays. The checker anyone can run is in the public Conduit download; the same rule applies here.
