Physical theories are built on axioms, and their merits depend on the depth and number of axioms. Newtonian mechanics adopts dual mass definitions plus an "equivalence hypothesis" as a patch; general relativity elevates the weak equivalence principle to a postulate, yet it remains a concrete physical assumption; the Time Field Theory (TFT) sinks its axioms to the meta-logical level of metric ontology and self-consistency, making the equivalence principle and the equivalence of inertial and gravitational mass natural corollaries. This paper further argues that a complete physical theory must simultaneously satisfy two constitutive criteria: deductive reasoning from axioms and falsifiable quantitative predictions. TFT forms a complete closed loop in both dimensions. Axioms are conventional logical starting points, and experiments can only verify corollaries rather than prove axioms themselves — no matter how high the precision of the Eötvös experiment reaches, it only narrows the failure boundary instead of granting a certificate of "absolute truth". The iteration of theories stems from the gradual deepening of axiom depth, rather than the negation of previous theories.
