Centimeter positioning lives or dies on one commitment: resolving carrier-phase measurements to the right whole numbers, in real time, with confidence you can defend. Today that commitment is made heuristically and validated by thresholds that quietly stop meaning what they say when conditions drift. QUADI makes the commitment exactly: proven-best resolution, a wrong-fix confidence bound that stays valid even when conditions don't match the model, and a certified decision every epoch — full fix, partial fix, or float, never an exception. It ships as a compact library built for the receiver, drop-in at the resolver interface, with a standalone verifier your safety case can run without QUADI in the loop.
