A field must hold together. The StructuralCoherence names the binding force that prevents a corpus from fragmenting under the pressure of its own heterogeneity: not uniformity, but regulated diversity. In the Socioplastics architecture, coherence is not sameness. The field integrates ten disciplinary domains. This is extreme heterogeneity. StructuralCoherence is what allows this heterogeneity to function as a field rather than as a collection. It identifies the binding mechanisms: the CamelTag system that provides a common vocabulary, the ScalarGrammar that provides a common syntax, the DOI layer that provides a common reference system, the dataset that provides a common analytical framework. These are not decorative additions. They are structural ligaments. Without them, the field's diversity would tear it apart. With them, the field's diversity becomes its strength. The StructuralCoherence is not a static property. It is a dynamic equilibrium. As the field grows, new binding mechanisms must emerge. As old mechanisms become obsolete, new ones must replace them. Node 2504 places this concept in Core IV because coherence is the fundamental condition of field existence. It is what distinguishes a field from a heap. Without this concept, the field is a list. With it, the field is a system.
