Decision Sovereignty: Case Studies

This volume presents four empirical case studies applying the Decision Sovereignty Framework developed in Fritz, Fritz-Kalish and Bodrova (2025). The framework formalises the variable Y = d (P) · S, where d (P) is decision capability — decision quality as a function of predictive capacity, P — and S is decision sovereignty — the structural capacity of an institutional system to transmit decisions into outcomes without blockage, attenuation, or reversal. The four cases are selected to span the complete outcome space of the framework. Case 1 (The Berkeley AI Paradox) illustrates a congestion failure: high d (P) with positive alignment, but execution infrastructure overwhelmed as AI-generated decision volume exceeded the stability boundary ρ*. Case 2 (TCG Pty Ltd) illustrates sustained high-S execution through a distributed architecture that expanded execution capacity in proportion to capability investment over more than five decades. Case 3 (Global Access Partners) illustrates pre-commitment sovereignty construction — deliberately raising governance capacity G before formal decision load arrives. Case 4 (Robodebt) illustrates the amplification failure mode: negative alignment (Sₙet < 0) combined with high automated execution magnitude, producing Y < 0 that grew more negative as scale increased. Each case reports DSI component scores (A, C, E, V), structural regime classification, and the mechanism through which the framework's predictions are consistent with the observed outcome. Evidence classification is explicit: the Robodebt case carries the strongest evidentiary load (Royal Commission record, parliamentary testimony, peer-reviewed academic analysis) ; the Berkeley case is illustrative only, pending peer-reviewed replication.
