LLMs Make Lean Proofs a Retryable Engineering Loop
ImperialViolet's zstd-in-Lean experiment shows proof automation becoming practical when the model can generate attempts and Lean provides strict deterministic verification.
Signal contract
ImperialViolet's zstd-in-Lean experiment shows proof automation becoming practical when the model can generate attempts and Lean provides strict deterministic verification. The signal shifts formal methods from rare expert ceremony toward a generator-verifier loop: LLMs can fail repeatedly while Lean cheaply rejects bad proofs and accepts only type-checking ones. Novelty: structural. Verification: source-inspected.
