Socioplastics [2514] expands StructuralCoherence as the internal consistency that allows a corpus to be read as proof. Coherence here is not stylistic uniformity, but load-bearing relation: concepts recur, nodes connect, slugs stabilise, references return, and the field becomes traversable across scale. This console explains why internal consistency matters more than external approval at the first stage of formation. A corpus proves itself by showing that its parts belong to one operative architecture, that its terms carry weight across contexts, and that its sequence can sustain navigation. Structural coherence transforms accumulation into form. Without it, many texts remain a pile. With it, the corpus becomes an epistemic building.
