万有引力常数G 的耦合张量结构:补充推导与技术说明 Coupling Tensor Structure of the Newtonian Gravitational Constant G: Supplementary Derivations and Technical Notes本文汇集与主文对应的扩展推导、方法学说明与符号表,内容包括结构涨落的本征几何标尺、球核基准G0 的详细闭式推导、δ0 = 1/(32π) 的归一来源、TACC 壳层再分配与ℓ = 1 二次回授的技术细节,以及q0 条件反演的流程与交叉检验说明。主文及其文内附录已给出本文所需的闭式链条;这里保留的是较长的对象层解释、扩展推导与方法学材料。This supplement collects the extended derivations, methodological notes, and symbollist corresponding to the main text. It includes the intrinsic geometric scale of structurefluctuation, a detailed closed-form derivation of the spherical-core baseline G0, the originof the normalisation of δ0 = 1/(32π), the technical details of TACC shell redistributionand the quadratic feedback of ℓ = 1, as well as the procedure and cross-check notes forthe conditional inversion of q0. The main text and its in-text appendices already providethe closed-form chain required for the present paper; what is retained here are the longerobject-level explanations, extended derivations, and methodological materials.
