Formally verified 3D mesh intersection - trust 93 lines of spec, not 1000+ lines of AI-written code
Can AI agents formally verify real-world Rust soure codes with Lean4?
Pre-alpha Idris 2 semantic kernel and reference scheduler for normalizing typed action sequences under an at-most-once policy, with tested but non-production service scaffolding.
A programming system where computers write and verify all code. Formally verified components with machine-checkable proofs, zero sorry.
A verifiably-bounded AI architecture: security from a small, formally-verified governor (the Warden) that holds authority over an untrusted learned core. Safety guarantee proved four ways — Z3, Coq/Rocq kernel, sympy, Lean. AGPL-3.0 + commercial dual-license.
A Rust crate extracted to Lean 4 by Charon/Aeneas and proved against hand-written specs, behind a reproducible Nix verification gate — the worked demo for the talk "Verified Components from Rust to Lean".
Prove a function in Lean 4, call it from C#. lean2il re-checks every proof with Tenet, an independent Lean kernel, compiles the kernel terms to .NET IL, and writes the docs from the Lean. With a VS Code extension.
