# 首个形式化验证的3D CSG实现：93行规范替代1000行AI代码

开发者展示了首个形式化验证的3D构造实体几何（CSG）操作——网格相交。该实现基于Lean 4编写，仅93行规范即可精确定义结果网格表面并保证实用良构性。相比之下，同类AI生成的代码通常需要1000行且未经验证。

## English Version

**First Formally Verified 3D CSG: 93-Line Spec vs 1000 Lines of AI Code**

A developer presented the first formally verified 3D constructive solid geometry (CSG) mesh intersection implementation in Lean 4. It uses a 93-line specification to guarantee correctness and well-formedness, while typical AI-generated code runs 1000+ lines without verification.
