A sorry-free Lean 4 formalization of the Classification of Finite Simple Groups, built on Mathlib and TauCeti.
Why you might care
Useful for anyone studying formal verification of large mathematical theorems or working with Lean and Mathlib at scale. It follows the first-generation CFSG proof and uses only standard axioms, with no native_decide. The full build is expected to take many hours, so it is more a reference artifact than a tool to run casually.
