Abstract Modern governance systems increasingly operate through layered technological infrastructures, hybrid public–private authority, and algorithmic decision systems. While such complexity enables coordination at unprecedented scale, it also introduces a structural hazard: authority becomes insulated from the consequences it generates, and visibility between institutions and populations becomes asymmetrical. When these conditions emerge, the feedback mechanisms that stabilize cooperative systems weaken, producing declining legitimacy, institutional fragility, and periodic crisis. This essay proposes a preliminary framework for Ecological Institutionalism, a design philosophy that treats institutions as regulatory environments within which human cooperative systems must remain capable of adaptive feedback. Drawing on insights from cybernetics, institutional analysis, complexity science, and the moral-ecological theory of cooperation developed within Disenchantment 2.0 / Reflexive Resource Regulation Theory (DT2/RRR), the framework identifies the preservation of reciprocal exposure between authority and consequence as a central condition of legitimate governance. By structuring institutions so that decision-makers remain structurally exposed to the outcomes of their decisions and populations retain meaningful channels of contestation and correction, complex societies may preserve legitimacy without abandoning expertise, coordination, or technological sophistication. The aim is not to eliminate institutional mediation but to design governance architectures capable of sustaining the ecological feedback conditions upon which durable human cooperation depends
