AbstractGenerative systems across physical, cognitive, and social domainsexhibit a common architectural requirement: complete resolution ofinternal structure leads to collapse rather than maximal productivity. This paper introduces the Echo-Excess Principle (EEP), which identifiesa structural no-collapse constraint necessary for generativity topersist. The principle holds that generative architecture requires twoco-constitutive conditions: (1) a no-collapse constraint (N) thatprevents total resolution, functioning not as a measurable quantity butas a boundary condition on allowable dynamics; and (2) a persistenceoperator (matter) that stabilizes distinction across time, allowingstructure to remain without immediate collapse. Neither condition alone suffices. Constraint without persistencecollapses immediately; persistence without constraint yields repetitionwithout novelty. Together, they define the minimal conditions underwhich structure can persist, differentiate, and complete. Empiricalobservations in two independent domains---online discourse communities(n = 19,160 comments) and institutional governance proceedings (n = 6meetings)---show alignment with a minimum unresolved architecturalfraction near 3/7, consistent with the theoretical derivation. Theframework exhibits structural correspondence with the Riemann Hypothesiscritical line at Re(s) = 1/2, interpreted as a boundary condition ratherthan a numerical target. Falsification conditions are specified. The framework predicts its ownnecessary incompleteness: any complete formal description of ano-collapse architecture must itself remain partially unresolved. Thisself-referential limit places the principle in the same class as Gödelincompleteness, the no-cloning theorem, and horizonconstraints---pre-dynamical laws that define the space in which eventsare possible, rather than causing events directly.
