Coupling Geometry Extensions: Global Supply Chains as Coupling Architecture

This second paper in the Coupling Geometry Extensions series applies the framework to the machinery that delivers the modern world — and to the doctrine that nearly broke it. Just-in-time did not fail, it argues: it succeeded, at its stated objective of maximising efficiency, and failed at an objective it could not perceive, because it had one metric (cost) and one direction (down), and lacked the one concept that mattered — a coupling threshold. The paper traces the ratchet from Ohno’s factory floor to the planetary web it became: buffers eliminated, suppliers consolidated, production concentrated until a single Taiwanese fabricator stood to the global electronics economy as the Roman Senate stood to provincial revenue. It shows the refractive field operating through the performance metrics themselves — managers rewarded for tightening the web, risk models calibrated to a coupling level that no longer existed — and reads COVID-19 not as a disruption but as a fold crossing: a $210 billion semiconductor cascade, a six-day blockage converted into weeks of global disorder. The post-pandemic record then confirms the redistribution theorem with uncomfortable precision: four years of reshoring rhetoric, an architecture substantively unchanged, and one instructive exception — the CHIPS Acts — where governments built channel-independent capacity instead of regulating the captured channels. Falsifiable predictions close the paper. Democracy as Coupling Architecture – Colonialism as Coupling Export
