Social reality becomes durable when dispersed relations acquire enough structure to govern what follows. A city, archive, building, curriculum or technical standard persists because heterogeneous forces have been aligned strongly enough to establish pathways for repetition, recognition and intervention. Once those pathways become ordinary, the history of their construction recedes from view and form begins to appear natural. Lefebvre, Foucault, Bowker and Star, Habraken and Benjamin approach this process from different directions, yet their strongest overlap lies in a shared concern with how relations become operative. Lefebvre refuses space as neutral container and shows it as a product of labour, property, representation and everyday practice. Foucault extends the argument into knowledge: discourses establish the conditions under which objects, concepts and speaking positions can appear as legitimate. Bowker and Star reveal how such rules become embedded in classifications, standards and administrative systems that distribute material consequences while hiding their histories. Habraken brings the architecture into a theory of levels, asking who may transform which part of a complex environment, under what conditions and without destabilizing the whole. Benjamin completes the sequence by showing how these structures become legible through montage, constellation and the arrangement of fragments. The overlap forms a single chain: relations produce environments; environments acquire rules; rules harden into classifications; classifications inhabit supports; supports distribute the capacity for transformation; and montage makes the resulting structure publicly legible. The chain can also be read in reverse. Montage reveals supports; supports expose classifications; classifications disclose rules; rules lead back to the relations from which the field emerged. This reversibility gives the framework its critical force. Power does not reside only in explicit commands. It operates in the arrangement of available action. A classification determines eligibility before an official decision is made. A support determines who may adapt a structure before conflict becomes visible. An archive governs return before interpretation begins. A field without stable supports cannot accumulate memory, coordinate action or become publicly usable, but a field whose supports cannot be questioned turns provisional arrangements into law. Durability therefore requires differentiation. Stability should belong to the elements that sustain collective continuity; flexibility should remain where future intelligence must operate. The strongest conclusion is not that everything is connected. What matters is that particular relations acquire the capacity to shape later possibilities. A category matters because it determines recognition. A support matters because it allocates control. An archive matters because it governs return. A spatial arrangement matters because it directs movement. A montage matters because it constructs attention. Social reality becomes transformable when its supports cease to appear natural. Knowledge becomes public when its rules of composition can be inspected. In Socioplastics, this architecture condenses as the passage by which relations become rules, rules become categories, categories become supports, and supports become publicly legible social form.
