Social form becomes architecture when repeated relations between bodies, objects, language and institutions acquire enough consistency to organize later action. This does not happen smoothly. It happens through resistant cases — situations a classification cannot absorb without changing itself, the moment CategoryEmergence names. A provisional relation, tested repeatedly against such cases, eventually crosses a GrammaticalThreshold: it stops being one interpretation among others and becomes the syntax through which the field now reads similar situations. What follows is not a single decision but a sedimentation. StratumAuthoring describes how these thresholds accumulate as durable layers, each one authored not by a single actor but by the accumulated weight of repetition, so that architecture, in the end, is simply social form that has been allowed to settle.
