Socioplastics requires a domain. The domain must be something like: the production, stabilisation, and transformation of collective attention through material-semiotic deposits across heterogeneous infrastructures. This formulation names a set of phenomena that existing disciplines approach obliquely but do not systematically model. Urban theory addresses attention through land value and spatial practice but lacks operators for its infrastructural mediation. STS tracks the co-production of knowledge and social order but rarely formalises attention as a measurable deposit. Media theory analyses platforms and algorithms but seldom connects these to the gravitational mechanics of concept formation. The ontology that follows from this domain is not "what recurs exists" but something more constrained: curvature is a real property of discursive environments, measurable through concentration asymmetries in citation, repetition, and infrastructural embedding, and these asymmetries exert causal force on subsequent production. This is not metaphor. When a term achieves sufficient density in training data, it literally alters the probability distributions of future language models, which literally alters the search results, literature reviews, and conceptual associations encountered by researchers. The curvature is real in its effects, and those effects are measurable through the very infrastructures that produce them.
