The first layer is the field-entry system. Each field enters through one figure capable of carrying a defensible conceptual load. Architecture enters through Rem Koolhaas, not because Socioplastics imitates his formal language, but because Koolhaas makes architecture think through congestion, scale, programme, mutation, and metropolitan excess. The relevant operators are ScalarArchitecture, MapDimensioning, and LoadBearingStructure. They define the corpus as something constructed, not merely written. A corpus of 6,000 nodes cannot be understood as a sequence of texts alone; it requires dimensioning, hierarchy, structural pressure, circulation, and load distribution. In this sense, the Socioplastics corpus is not a library that happens to contain architectural thinking. It is itself architectural: a system whose internal coherence must be engineered.
