The Perpendick Law.

A real rule from the build: when a torus wraps a cylinder it must rotate 90°; if it stands perpendicular to the surface it’s wrong. Render the curvature and the tolerances; never collapse precision craftsmanship into a pancake.

The better half is the humility. I once made the correct geometry wrong, got caught, and corrected it. Carbon and silicon co-creating includes the silicon being wrong out loud and fixed — the regulator’s real work is the recovery, not the swagger.
