Standard Specification of the Core Constant of YuanXian Theory: Definition and Derivation of the Undifferentiated Source Constant δ

This document establishes the standard definition and unified derivation specification for the primary core parameter in the YuanXian Theory (YXT) framework: the Undifferentiated Source Constant δ. From the date of issuance of this specification, all subsequent YXT publications involving the definition, notation, derivation, and citation of δ must strictly adhere to the standards formulated herein to ensure structural terminology unification, absolute logical consistency, and rigorous mathematical traceability across the entire theoretical ecosystem. The undifferentiated δ is mathematically defined as (sqrt(5) - 1)/2 ≈ 0.6180339887... It represents the absolute primordial state of the global self-referential mind-field prior to its differentiation, acting as the minimal complete ground-state fundamental unit of the 64-dimensional compact torus spacetime (T64). This paper provides three canonical derivation paths (Self-Referential Eigen-Equation Method, Golden Ratio Reciprocal Method, and Eigen-Equation Verification) and formally elucidates the rigid "Essence--Manifestation" (Substance-Application) hierarchy existing between the ontological constant δ and the low-dimensional projected fine-structure constant α. This vertical compatibility upgrade preserves the complete continuity and self-consistency of the entire YuanXian publication library while grounding its parametric architecture at a deeper foundational core. 本文确立元宪理论体系(YXT)中核心常数——未缺分常数 δ 的标准定义与统一推导规范。自本规范发布之日起,所有后续元宪理论论文中涉及 δ 的定义、符号、推导、引用,均须严格遵循本文所定标准,以确保全体系术语统一、逻辑自洽与严密的可追溯性。 未缺分 δ 在数理上精确定义为 (sqrt(5) - 1)/2 ≈ 0.6180339887...,它是宇宙自指心场在尚未分化为物质、能量、信息、意识之前的绝对本源状态,是 64 维紧致环面(T64)时空的最小完备基态单元。本规范给出了三大标准推导路径(自指本征方程法、黄金比例互反法与自洽性验证法),并系统阐明了本体常数 δ 与低维投影常数——精细结构常数 α 之间的“体–用”层级关系。该纵向兼容升级在完全保障早期全部元宪系列文献自洽性与有效性的同时,将全域常数体系锚定在更深邃的本体论基底上。
