# Formally Verified 3D CSG: Trust 93-Line Spec, Not 1000 Lines of AI Code

A developer presented a project on Hacker News that uses formal verification for 3D constructive solid geometry (CSG). The project's correctness relies on a compact 93-line specification rather than thousands of lines of AI-generated code. This approach highlights a method for achieving high reliability in geometric modeling, contrasting with less trustworthy AI-based solutions.
