The Lean layer
E8 and the Gaussian code
The algebraic cores are formalized in two Lean 4 modules over Mathlib Moura21,mathlib, committed to the repository's Lean project ( lake build green, no sorry, no native_decide): GaussianCodeBridge.lean ( [formula in source] theorems) and QuarticHalf.lean ( [formula in source] theorems), [formula in source] kernel-checked theorems in total. The finite certificates are proved by the kernel-checked decide tactic over e
