PFUSRC-106 to PFUSRC-110 form a complete closed-loop subsystem under the PFUSRC theoretical framework for topological unification of particle physics and four fundamental interactions. As the capstone retrospective paper of this subsystem, this manuscript introduces no new axioms, derivations or experimental predictions. Instead, it delivers a systematic overview of the five sequential papers, reconstructs their complete logical chains, and delineates their hierarchical boundary relationships. This paper sequentially restates core contents of each document: the ontological substrate of Primordial Unity and the elimination of artificial positive-negative binary fallacies proposed in PFUSRC-106; the definition of topological rheology tensor and intrinsic geometric derivation of gauge fields in PFUSRC-107; topological intrinsic regularization and geometric reinterpretation of QED quantum corrections in PFUSRC-108; topological geometric explanation of quark confinement and the strong interaction in PFUSRC-109; and topological redefinition of the weak interaction plus geometric reconstruction of the Higgs mechanism in PFUSRC-110. On this basis, it compiles a unified summary table covering all four fundamental interactions within the PFUSRC system, sorts out the logical inheritance, axiom transfer and subordinate hierarchical relations across the five papers, and systematically organizes core innovations of this subsystem, paradigm demarcations against mainstream physical theories, as well as unresolved follow-up quantitative research tasks. This retrospective serves as a full navigation framework for the particle physics sector of PFUSRC, and provides clear logical starting coordinates for the subsequent PFUSRC-112 and PFUSRC-113 research papers.
