In response to AI agents discovering vulnerabilities in the Lean proof assistant's kernel, Lean v4.35.0 introduces the `lake check` command and four additional independent kernels (e.g., nanoda, lean4lean) for sandboxed re-verification. This update aims to ensure logical soundness of formal mathematical proofs through multi-kernel cross-validation against automated attacks.

    • AI agents have become a primary source of discovering kernel vulnerabilities in the Lean proof assistant, prompting stronger defensive mechanisms.
    • Version 4.35.0 adds the `lake check` command, enabling users to re-verify projects using multiple independent kernels within a sandbox environment.
    • Four additional kernels (nanoda, lean4lean, con-leche, con-ron) are introduced to facilitate cross-validation and ensure proof correctness.
