Urban Hemodynamics II: The Engineering Implementation and Service Ecosystem of the Carbon-Silicon Symbiotic Network

[Abstract] This paper serves as the engineering realization of the ethical framework established in "The Civilizational Covenant" (Jia, 2026). We propose "Dynamic City," a decentralized, edge-first operating system that translates theoretical "Urban Hemodynamics" into physical reality. By introducing the V-Hub (Vehicle Hub), the Passive Exposure Protocol, and a Metabolic Service Ecosystem, we construct a traffic governance architecture that eliminates the "Isolated Island" effect. This system transforms the city into a living organism where every node—vehicle, human, and infrastructure—acts as an "Interactive Eye," ensuring safety through collective perception, efficiency through fluid dynamics, and justice through algorithmic equity. Key Mechanisms: V-Hub Architecture: De-GPS reverse localization and liability locking. Passive Exposure: The "Ghost Car" paradox and immune response. Bubble Theory: Sentinel, Pedestrian, and Encryption Bubbles. The Lifeline: Dynamic emergency relay and family convoy protocols. [摘要] 本文是《文明契约》伦理框架的工程实现版。我们提出了 “动态城市” (Dynamic City) 架构,通过去中心化的 V-Hub(外挂式车载中枢)、分级感知网格 以及 代谢型服务生态,构建了一套兼容现有车辆、具备自我免疫能力的城市操作系统。 本文详细阐述了从“幽灵车”的被动暴露机制到“生命接力”的急救协议,展示了如何用代码和硬件将“文明契约”固化为不可违背的物理铁轨,实现“硅基守护碳基”的终极愿景。 Series Context:This is Paper No. 02 in the Symbiosis Sequence. It is an extended inquiry based on the foundational work:Foundation: The Civilizational Covenant (DOI: 10.5281/zenodo.18371344).
