formal verification

MathCode is a terminal AI coding agent for mathematical formalization: it turns plain-language math problems into Lean 4 theorems and attempts formal proofs, with a persistent Lean REPL and supporting theorem/axiom libraries.

A Lean 4 project for formally verified 3D mesh intersection and constructive solid geometry, with a browser demo for intersecting example meshes or STL imports.

A capability-based microkernel written in SPARK Ada and formally verified with gnatprove, with a thin C SDK for building services and distribution components.

A Python filter layer for LLM apps that evaluates responses against a Lean-verified Scherf logic backend and can pass, flag, correct, or block output.

An autonomous neuro-symbolic formal verification engine for Lean 4. The repository describes a proof workflow that generates tactics and then checks them deterministically in Lean, with example proofs, verification steps, and telemetry outputs.
