The physical question is when a relational configuration can support consistent references in three independent directions. The numerical threshold follows from that geometric requirement. It is not an arbitrary size chosen to resemble a cosmological observation.

The word referenceable has a specific role. It concerns whether a realized domain can support the physical relationships needed for measurement. Before that condition is met, MQ does not treat the underlying count description as an ordinary small object already embedded in measurable space.

The threshold is therefore different from a directly observed radius of the universe at an early time. It is a consequence of the framework’s assumptions about closure. Nor should it be substituted for every conventional early-universe length scale without deriving the physical relationship between them.

The manuscript connects this condition with the transition into a stable System Frame. Subsequent expansion and cosmological behavior require additional relations. A minimum closure geometry cannot, on its own, establish the observed microwave-background spectrum or the later distribution of matter.
