Show HN: Formally verified 3D CSG: Trust 93 lines spec, not 1000 lines AI code

- What happened
- A formally verified 3D mesh intersection algorithm in Lean 4 requires reviewing only 93 lines of specification, not 1000+ lines of AI-written implementation code.
- Why it matters
- Engineers building safety-critical CAD, robotics, or manufacturing software where mesh operations must be mathematically guaranteed correct without trusting AI code.
- Watch out
- The verified kernel runs 24 seconds for complex meshes versus milliseconds for unverified implementations; performance was deprioritized for reviewability and correctness guarantees.
