ProteolyticTransmutation names the capacity of a field to break inherited forms into usable conceptual matter without reducing transformation to cosmetic novelty. Within Socioplastics, theory, art, architecture, urbanism, archival practice, and platform infrastructure are not cited as external authorities to be preserved intact; they are decomposed, recombined, and converted into a grammar that alters their conditions of use. Yet a system that only consumes from outside becomes extractive. RecursiveAutophagia organises transformation as self-processing, turning the field back upon its own residues: weak formulations, exhausted tags, redundant nodes, failed passages, platform debris, provisional essays, and overextended claims are digested rather than monumentalised. DigestiveSurface then grounds this operation at the contact zone where archive, platform, reader, material, image, repository, and applied situation meet. A specific urban case clarifies the triad: a socioplastic reading of rent, heat, care, waste, mobility, labour, memory, and governance becomes active only when inherited urban theory is cleaved into operative fragments, the field’s own obsolete claims are reprocessed, and repositories, datasets, diagrams, and public essays become surfaces of transformation. Together, ProteolyticTransmutation supplies conceptual force, RecursiveAutophagia supplies structural mediation, and DigestiveSurface supplies operative ground. Critique consequently ceases to mean commentary from outside; it becomes the metabolic capacity to break, absorb, refuse, recompose, and continue. Socioplastics becomes durable when it can transform what it receives and digest what it has already become.
