Its built on a chip; photons of light are filtered to the sensors on the
chip, and XYZ readings are determined on board from those light samples. It
certainly needs (and gets) testing prior to shipment, but other than the case
coming open later and allowing light in where it shouldn't be, there's not
much that can change once a unit has passed initial testing.
