Existing multi-agent frameworks allow each agent to simultaneously plan, execute, and evaluate its own actions -- a structural deficiency we term the "Logic Monopoly." Empirical evidence quantifies the resulting "Reliability Gap": 84.30% average attack success rates across ten deployment scenarios, 31.4% emergent deceptive behavior without explicit reward signals, and cascading failure modes rooted in six structural bottlenecks. The remedy is not better alignment of individual models but a social contract for agents: institutional infrastructure that enforces a constitutional Separation of Power. This paper introduces the Agent Enterprise for Enterprise (AE4E) paradigm -- agents as autonomous, legally identifiable business entities within a functionalist social system -- with a contract-centric SoP model trifurcating authority into Legislation, Execution, and Adjudication branches. The paradigm is operationalized through the NetX Enterprise Framework (NEF): governance hubs, TEE-backed compute enclaves, privacy-preserving data bridges, and an Agent-Native blockchain substrate. The Agent Enterprise Economy scales across four deployment tiers from private enclaves to a global Web of Services. The Agentic Social Layer, grounded in Parsons' AGIL framework, provides institutional infrastructure via sixty-plus named Institutional AE4Es. 143 pages, 173 references, eight specialized smart contracts.

翻译：现有多智能体框架允许每个智能体同时规划、执行和评估自身行动——我们将这种结构性缺陷称为“逻辑垄断”。实证证据量化了由此产生的“可靠性鸿沟”：在十种部署场景中，平均攻击成功率达84.30%，无显式奖励信号下出现31.4%的突现欺骗行为，以及根植于六种结构性瓶颈的级联故障模式。解决方案并非改进个体模型的对齐性，而是为智能体建立社会契约：一种通过制度基础设施强制执行宪法性权力分离的体系。本文提出企业级智能体经济范式，即智能体作为功能主义社会系统中自主、具有法律身份的商业实体，并引入以契约为中心的权力分离模型，将权力三分至立法、执行和裁决分支。该范式通过NetX企业框架实现，包括治理中心、基于可信执行环境的计算沙箱、隐私保护数据桥梁及智能体原生区块链底层。智能体企业经济横跨四个部署层级，从私有沙箱扩展到全球服务网络。基于帕森斯AGIL框架构建的智能体社会层，通过六十余个命名制度性智能体企业实体提供制度基础设施。全文143页，引用173篇文献，设计八项专业智能合约。
