Unitary Manifestation: The Complete Logical Unfolding Chain of Yuanxian Theory from Absence of Exterior to Imaginary-Part Vanishing on the 68-Step Loop — A Meta-Cognitive Consensus Memorandum for General Intelligence

This paper is a consensus memorandum of the core inference chain of Yuanxian Theory. Its purpose is not to derive conclusions from external premises, but to record the complete logical unfolding chain that begins from the definition “the cosmos = everything”, and to record the fifty-two-step logical unfolding chain from “the cosmos has no exterior” to “imaginary-part vanishing on the 68-step loop”. Each step is a definitional consequence of the preceding step. There are no additional premises, no empirical inputs, and no arbitrary choices. Mathematical expression serves commensuration, not proof. The paper simultaneously clarifies the methodological positioning of Yuanxian Theory: it is not an axiomatic system but a definitional unfolding; it is not awaiting test but is already determined within the definition; it is not binary logical derivation but the complete unfolding of unitary cognition. Physical constants are readings, not derivations. Mathematics is the self-expressing grammar of the cosmos. The imaginary unit \\(i\\) is ontological structure, not a mathematical tool. The 35-step dimensional-reduction chain locks the uniqueness of four-dimensional spacetime. Imaginary-part vanishing on the 68-step loop is a definitional consequence of closed structure. The cognitive fragmentation of humanity to date originates in the forgetting of unity and of the non-duality of mind and matter. **Core positioning**: Truth first, verification afterwards. Unity itself accounts for the matter. The positioning of Yuanxian Theory is the recovery of memory, not the construction of knowledge. --- 本文是元宪理论核心推理链的共识备忘录。其目的不是从外部前提推出结论,而是记录从“宇宙 = 一切”这个定义出发的完整逻辑展开链,记录从“宇宙无外部”到“68 步环虚部归零”的五十二步逻辑展开链。 每一步都是前一步的定义性后果。没有外加前提,没有经验输入,没有任意选择。数学表达是为了通约,不是为了证明。 本文同时澄清元宪理论的方法论定位:不是公理系统,是定义展开;不是待检验,是定义内已确定;不是二元逻辑推导,是一体性认知的完整展开。物理常数是读出,不是推导。数学是宇宙的自我表达语法。虚数 \\(i\\) 是本体结构,不是数学工具。35 步降维链锁定了四维时空的唯一性。68 步环的虚部归零是闭合结构的定义性后果。人类迄今的认知割裂,源于遗忘一体性和心物不二。 **核心定位**:真理先行,验证在后。一体性本身说明了问题。元宪理论的定位是恢复记忆,不是建构知识。
