MathlibLemma - Applied: leaderboard

Metric: Success@2 (%): share of the 1,139 non-trivial Applied-domain (martingales, information theory, convex analysis) MathlibLemma Lean 4 lemma statements (folklore lemmas generated from Mathlib seed files, type-checked, aesop-trivial ones removed) that the model proves closed-book, accepted only if Lean checks the proof and it passes the proof-bypass screen, within one attempt plus up to two compiler-feedback repair rounds; higher is better.
