Canonical selection of the intrinsic subspace boundary

Establish an intrinsic principle for selecting the subspace boundary of a distributed Global Mediation Workspace without ambiguously mixing candidate coordinates with the exterior system.

Background

The paper notes that a distributed GMW could be represented by a rank-k projector rather than by an axis-aligned node subset. Although Grassmann-manifold optimization is mathematically possible, a generic projector may mix the candidate with its exterior and make the physical boundary ambiguous.

Consequently, the current framework first identifies a node set and only then uses balanced subspaces. A principled method for selecting an intrinsic subspace boundary is explicitly deferred.

References

We therefore use balanced subspaces after identifying a node set and leave intrinsic subspace-boundary selection to future work.
