This article presents an original systems-level framework for integrated public service design, governance, and resilience, with particular emphasis on the alignment of human, animal, and environmental needs within a unified legal and institutional architecture. The work develops a structured model grounded in rule-of-law principles, separation of powers, and accountability mechanisms, and proposes a scalable approach to public service delivery that addresses systemic failure across healthcare, welfare, housing, environmental protection, and institutional governance. The article is authored independently and is supported by an openly available dataset and technical materials hosted on GitHub and Zenodo. It is intended for policymakers, legal scholars, systems architects, and interdisciplinary researchers concerned with governance reform, public service integration, and long-term societal resilience.
