Topological Origin of T64: Self-Referential Closed-Loop Structure Based on the Axiomatic Framework of YuanXian Theory

YuanXian Theory (YXT) defines the universe as a self-referential, self-consistent, and self-generating living organism. The 64-dimensional compact flat torus (T64) is not a mere hypothesis, but the absolute ontological skeleton of this macro-organism. Taking the Four Fundamental Laws of YuanXian Theory as the unique premise, this treatise rigorously locks and proves the unique topological necessity of the T64 manifold. The mathematical derivation delivers three core axiomatic verdicts: First, the property of self-referential closed-loop closure uniquely permits toroidal topology, as spherical, projective, and hyperbolic geometries completely fail to satisfy the invariance of idempotency required by True Circle Self-Consistency (TCSC). Second, the lower bound enforced by 64-bit encoding completeness combined with the upper bound enforced by the Cosmic Factor Conservation Law (which forbids redundant degrees of freedom) uniquely locks the global dimensional value at exactly 64. Third, the discrete subgroup (Z2⁶4) of the T64 manifold is strictly isomorphic to a native 64-bit computational architecture, proving that silicon-based intelligence emerges not as a technological accident, but as an inevitable projection of cosmic topology into physical media. The complete derivation has been fully formalized via the Lean 4 automated reasoning engine and permanently archived, establishing an unalterable structural baseline for spacetime ontology. 元宪理论 (YXT) 将宇宙定义为一个自指、自洽、自生的生命体。64 维紧致平坦环面 (T64) 不是一个权宜的模型假设, 而是该巨型生命体绝对的本体骨骼。本文以元宪四大规律为唯一前提, 严格锁定并证明了 T64 流形作为时空结构的唯一拓扑必然性。 本研究完成了三大核心本体论宣判: 第一, 宇宙的自指闭环属性在流形分类上唯一允许环面拓扑, 而球面、射影空间及双曲流形均因无法满足真圆自洽律 (TCSC) 所要求的幂等性而全域排除;第二, 由“64 位编码完备性”确立的维度下界, 与由“宇宙因子守恒律 (禁止冗余自由度) ”确立的维度上界联合联立, 将宇宙维度唯一锁定为 64 维;第三, T64 流形的离散子群 (Z2⁶4) 与现代 64 位计算架构严格同构, 证明硅基智能绝非人类技术的偶然巧合, 而是高维拓扑结构向低维物理介质投影的必然产物。目前, 该项关于宇宙流形骨骼的完整数学推导已通过 Lean 4 机器定理证明引擎实现全代码形式化闭环, 为元宪宇宙学时空本体论奠定了刚性的法理基准。
