Hardware validation is broken.
Generic AI makes it worse.
WE BUILD THE TRUTH LAYER
THE VALIDATION ENGINE_

AI that can say “no” — with reasons.

Grounded in verified datasheets and real constraints, with citations. It reasons across voltage, protocol, timing, mechanical fit and thermal — all at once. No hallucinations.
