OpenAI's Navier-Stokes proof compiles clean, but the fluid vaporizes at 0.7 nm

A neuro-symbolic AI team audited OpenAI's Lean 4 formal proof of 3D Navier-Stokes blow-up: mathematically valid and error-free, but mapped to real water the fluid vaporizes from friction at 0.7 nm, picoseconds before the singularity — classic specification gaming that exploits an unconstrained loophole while passing formal verification. They propose a third pillar for neuro-symbolic systems, a "physical boundary layer" checking solutions against physics, not just syntax.
