This paper establishes a complete dual-time system based on the PFUSRC global rigid axiomatic system and the cone-edge interlayer truncated domain theory, revealing that the physical essence of time is not an independent dimension but a derivative effect of spatial topological structures. The study demonstrates that helical time constitutes the ontologically dominant component of causal evolution, while photon time serves only as a macroscopic apparent observational component. The so-called time compression phenomenon is essentially the geometric result of interlayer space expansion, helical topological folding, and causal density enhancement. Based on the coaxial bicone topology, interlayer truncated domain structure, and intelligence-monad dominance mechanism, this paper completes the ontological demonstration of the dual-time system and indicates its universal significance in cosmic structure, information transmission, and system evolution. The τ-scaling phenomenon emerging in contemporary semiconductor fields is internally consistent with the topological evolution law described in this theory, which can be regarded as a cross-scale verification of interlayer space and geometric determinism. The research directions opened by the PFUSRC system—including cone-edge interlayer, intelligence-monad space, high-dimensional causal paths, and the ontological rectification of form-shell hierarchy—possess extremely rich mathematical structures and physical connotations. The relevant theoretical system has been systematically elaborated in a series of papers.
