本文提出“存在迭代论”（Existence Iteration Theory, EIT）4.0 的形式化框架。 其目标不是预设世界中有哪些对象，而是研究：在给定观察尺度、可干预集合、预 测窗口和测量误差条件下，能否从原始相互作用历史中自动提取有效状态、识别个 体边界与身份、判断其存在资格，并进一步刻画多个下层存在形成上层存在以及上 层结构反向约束下层动力学的条件。本文首先以干预后的未来响应定义最小充分状 态 ，随后构造边界—身份联合自洽核 ，并以个体化余量、身份 可恢复余量和关系参与余量构造存在余量 。在此基础上，本文区分集合、宏观 变量与上层存在，利用动力学闭合与干预一致性建立条件性的跨层生成定理；再以 状态依赖约束算子 形式化上层对下层的反馈。最终，EIT 4.0 被压缩为状态压 缩、存在发现、跨层生成和跨层反馈四类算子的迭代闭环。本文明确区分定义内的 形式结果与尚待验证的自然科学主张，并提出一个无标签 Toy World 实验以及一组负 对照和证伪条件。该框架的主要研究价值不在于重新发明因果状态、Markov 边界、 lumpability 或 causal abstraction，而在于尝试把这些分散工具组织为同一个“存在发现 —层级生成—反馈—再迭代”的统一研究程序。

This article starts from the relativity of our perception of the real world, clearly stating that our perception is in an intermediate state between the formation of the world and the cognition of the world. Only by continuously exploring and interacting with the systems that affect us can we have a deeper understanding of our world. Regarding the core philosophical question, "existence", it also conforms to this characteristic. We study and analyze existence and define it as: existence is a system that maintains interaction with the outside world and continuously reproduces in a continuous process. From this analysis, we examine the imperfection, periodicity, and iterative evolution of existence. We learn that existence is a living entity, and immortality does not exist. The world principle is unified, from the quantum to the universe's material world, from individuals to society, and the spiritual world of knowledge products. Based on this principle, we provide new interpretations such as resonance, hoping to contribute to scientific research analysis and the evolution of the world. We will also continue to iterate and optimize the process of iterative evolution, and make it more specific.
