PFUS Unified Framework: Explicit–Implicit Seven-Yuan Logic, β₁ Primitive System and Global Structural Closed-Loop of Pendulum Ion System

Aiming at the fragmentation of modern fundamental physics, the absence of a global unified framework, and observational bias inherent in traditional cognition, this paper constructs a double-layer symmetric logical architecture of Explicit Seven-Yuan Logic and Implicit Seven-Yuan Logic based on the PFUS Primitive Unified Theoretical System. It clarifies the hierarchical positioning and operational mechanism of all units within the system. The Explicit Seven-Yuan is defined as fundamental logical units with mathematical deducibility and explicit characterization. Following the principle of mirror isomorphism, the internal composition of the Implicit Seven-Yuan is rationally presumed via theoretical hypothesis and further embodied as Pendulum Ion 1–7, which are designated as the top global order-controlling core. All other diffuse, sparse and flattened fundamental units within the β₁ primitive system are uniformly defined as β₁ Primitive Basal Units, clarifying the hierarchical boundary between the core regulatory layer and the global basal layer. This paper redefines the academic connotation of High-Order Perturbation and corrects the cognitive bias that judges existential weight merely by visibility. It establishes a complete logical chain covering primitive ontology, hierarchical architecture, field operation and global integration, achieving self-consistent closed-loop, global compatibility and primitive unification of the PFUS system.
