A.16.0:4.2 - Position-account discipline
The position read by this pattern is the slot-explicit claim defined in C.2.2a: a partial coordinate publication in the declared language-state U.CharacteristicSpace, where each basis-slot reading is published as a ValueSet(slot), interval, or other admissible set-valued claim.
Early seam publications may leave some slots unknown or wide. That uncertainty is admissible only if it is explicit. A trajectory account therefore records the position claim for the current episteme edition and, when needed, for predecessor or sibling editions that justify the move reading.
