Ontology of Huzhi Grammar: Underlying Logic and Meta-Rule Framework (v1.0.0 Final)

Abstract Human cognitive activities have long relied on an operational tool called "Subject-Object Grammar." This tool is efficient and reliable when parsing simple mechanical systems; its status is equivalent to application software within an operating system—task-specific, function-specific, and fully competent. However, when facing highly complex, networked contemporary systems, tools at the application layer alone are insufficient. Setting aside all concrete empirical cases, this paper systematically expounds the axiomatic system of "Huzhi Grammar" as an underlying operating system purely at the ontological level. It defines the first principle of "relation precedes entity," establishes the "Line-Cutting Test" as the core criterion for determining system nature, and derives a "meta-rule framework" for addressing complex network systems. This paper aims to provide a self-consistent, self-sourced infrastructure for upgrading human cognition from application-layer tools to an underlying operating system.
