Paper Description: Institutions rarely fail because they abandon their mission. More often, they lose what they still claim to value while performance indicators remain strong. This paper shows how that loss occurs. It argues that institutional fragility is introduced not at the moment of crisis, but earlier—when declared purpose is translated into the criteria that guide resource and capital allocation. As intent moves through layered governance systems, protective and long‑horizon conditions can gradually be reclassified as inefficiency. Reported performance may improve even as the capacity to absorb uncertainty is reduced. Drawing on the Coherence Programme’s Operating Spine, the paper identifies the Translation Interface as the structural site where drift is introduced and formalizes the Sovereign Window—the interval during which shifts in criteria can still be detected before they become embedded in budgets, routines, and performance signals. The contribution is structural rather than normative. The paper introduces a framework for translation traceability, applicable across public governance, capital allocation, portfolio management, and AI‑mediated decision systems. Paper 14 serves as the conceptual entry point to the Coherence Programme. Programme Description: The Coherence Programme examines how institutional decision systems maintain—or lose—fidelity to declared intent under conditions of complexity, scale, optimization pressure, and delayed feedback. The programme models governance as a translation architecture. Using the Operating Spine, it traces how purpose moves through Capabilities, Value Drivers, Strategy, Portfolio, and Signals, becoming progressively encoded into measurable criteria and allocative rules. At the interfaces between these layers, translation drift, coherence, and corrective intervention can be analyzed structurally. Across its papers, the programme establishes translation traceability as a foundational concern of modern governance. The research applies to public institutions, capital allocation systems, portfolio governance, and AI-mediated decision environments—where the durability of decision rules determines institutional reliability over time.
