This deposit presents **Version 23/F3 of the Invariant Temporal Ordering Framework (ITOF) **, released under the official preprint designation `ITOFV23F3ₚreprint`. ITOF is a foundational framework for distinguishing physical change, prior–later succession, measurement, representation, and temporal ontology. It begins from an explicit universal postulate: every admissible identity-extended physical system undergoes sustained realized change. On every realized identity-preserving history chain, each occurrence whose identity continues is followed by a later occurrence with a physically non-identical complete condition. This postulate is motivated by convergent evidence from heterogeneous physical domains, but it is not presented as the result of exhaustive observation of every physical system or every stage of change. For an arbitrary system within the postulate domain, ITOF distinguishes realized physical occurrences, complete physical conditions, derived stages of change, analytical references, measurements, records, and numerical differences. Physical change is attributed to the constituted system and its realized history; it is not relocated into time. Time in ITOF is defined as the universe-wide descriptive expression of the continuing, non-reversing extension of physically realized prior–later succession across the identity-preserving histories of admissible physical systems throughout the universe. Temporal meaning is distinguished from its formal representation as a strict partial-order structure. The prior–later relation is irreflexive and transitive, while no total order is imposed on physically unrelated occurrences. ITOF therefore introduces neither a universal clock value nor a preferred reference frame. Time is not treated as matter, energy, a field, a physical system, a force, or an independent causal agent. A central result of V23/F3 is the separation of temporal meaning from metric, geometric, and operational quantities. Clocks measure through their own physical change; proper time, coordinate time, signal intervals, and geometric quantities retain their established mathematical and empirical roles. Their operational and predictive success does not, by itself, establish an additional physical agency or substance called time. The framework formulates a typed non-transfer principle: a valid result in one category—measurement, representation, geometry, dynamics, or statistical inference—cannot be transferred automatically into a distinct ontological category without an explicit and physically justified bridge. ITOF neither replaces nor modifies the dynamical equations of special relativity, general relativity, quantum mechanics, or other established physical theories. Its contribution is different: it provides a rigorous architecture for temporal meaning, physical attribution, measurement discipline, admissible representation, domain-level specialization, and foundational testing. Version 23/F3 consolidates the formal ontology of physical occurrences and histories, sharpens the treatment of clocks and distant physical records, preserves established relativistic quantitative relations while clarifying their ontological attribution, examines the stationary quantum-state challenge, and distinguishes system-level empirical tests from genuine framework-level or ontological discrimination.
