A hybrid method uses LLM-generated proof strategies and lemma selection to raise a specialized Lean prover's miniF2F pass rate to 55.3% at 128 attempts, above the baseline's 54.9% at 3200 attempts.
• If a lemma makes an assertion not present or derivable from the NL proof and global hypotheses, it’s incorrect
