Scientific and technical search processes unfold under finite conditions. Limited resources meet growing model complexity and generate a structural tension between the consolidation of existing orders and the opening of the search space for alternative transitions. Although this tension has been described across various disciplines, a generic architecture that explains under which conditions the relative priority between consolidation and exploration shifts is frequently lacking. This paper reconstructs that shift as a problem of structural search efficiency under finite conditions.The operative vocabulary employed here is derived as a local architectural extraction from Epistemics as Model Management Under Finite Conditions (Rapp 2026a). In this sense, epistemics is understood here simultaneously as an epistemic infrastructure from which the search architecture is locally differentiated. The paper lays no claim to an independent metatheory, but to a specialized elaboration of search governance under finite conditions. Its contribution lies in the explication of a dual-mode architecture of model management, in which search processes are described as dynamic reweightings between stability consolidation and exploratory opening. Within this local search architecture, validity is operatively construed as robustness under perturbation, costs as the effort required to maintain or revise stabilized structures, and friction as a diagnostic indicator of a declining ratio of robustness gain to effort. Increasing friction density, robustness plateaus, and nonlinear tension dynamics mark threshold configurations at which a priority reweighting in favor of exploratory transition types becomes structurally plausible. The architecture neither replaces disciplinary theories nor provides guarantees of truth; it renders the governance logic of finite model spaces explicitly formulable.
