Substance-Function-Telos Ontological Meta-Axiom Set: Completeness Criterion, Valid Boundaries, and Division of Labour with Ontological Folding

The Substance-Function-Telos meta-axiom set constitutes a formal syntax at the ontological level, which only judges whether an ontological narrative satisfies minimal completeness; it provides a necessary but not sufficient condition. This paper systematically delineates five hierarchical boundaries for the application of this meta-axiom set: it only tests formal self-consistency without verifying physical instantiation; it does not intervene in the substantive filling of the substrate; it cannot autonomously classify whether an ontological structure belongs to cognitive space or the physical world; it lacks cross-domain discriminative capacity, and cross-domain verification must rely on the higher-order meta-operator of ontological folding; it suspends the problem of primordial differentiation. This paper further clarifies the ontological status of cognitive space: cognitive space emerges from primordial manifestation and possesses intra-domain reality, yet it is not equivalent to physical reality. A standardized operational workflow is thereby established: first conduct formal screening via Substance-Function-Telos, then perform cross-domain attribution verification via ontological folding. This two-step procedure prevents the logical fallacy of equating logical self-consistency directly with physical reality and closes loopholes against the misuse of ontological frameworks.
