C.2.2a:4.2 - Position reading under A.19
A language-state position is a partial, slot-explicit coordinate claim in the declared language-state U.CharacteristicSpace.
Publish each basis-slot reading as a ValueSet(slot), interval, or other admissible set-valued claim. Early seam publications may leave some slots unknown or wide, but that uncertainty must be declared rather than hidden inside one stage word.
position language is therefore admissible here only as shorthand for such slot-explicit A.19 coordinate claims. It does not authorize a rival process-sequence or feature-vector story.
