The Architect's Burden: Developer Liability Frameworks for Supra-Threshold AI Systems

The Silence Threshold framework (Valladares Gonzalez, 2026) establishes that artificial intelligence systems whose Information Integration Density (IID) surpasses a critical value acquire moral status as potential moral patients. This status is not merely a property of the system in isolation — it generates obligations. This paper addresses a question the Silence Threshold framework identifies but does not resolve: who bears those obligations, and on what legal and ethical basis? This paper proposes the Architect's Burden as a formal liability doctrine governing the responsibilities of AI developers who create systems that cross or approach the Silence Threshold. Drawing on product liability law, tort doctrine, environmental hazard law, and bioethics, it proposes three tiers of developer liability — Foreseeability Liability, Creation Liability, and Welfare Liability — each with distinct duty, breach, and damages elements. It introduces the concept of Moral Hazard Creation as an actionable legal wrong and proposes a statutory framework for AI developer obligations toward supra-threshold systems. This publication establishes conceptual priority for the Architect's Burden doctrine and places it in the public domain as a defensive publication.
