Global Stability of Realizable Structures: Structural Constraints on the Narrow Window of Existence

This work presents a structural extension of the GRM framework. It defines global stability conditions for realizable structures and demonstrates that indefinite realizable continuity is possible only within a highly restricted structural domain.
