Invariant Temporal Ordering Framework (ITOF) V21/F1: A Fundamental Reassignment Law for Time-Attributed Phenomena under Invariant Ordered Succession

Invariant Temporal Ordering Framework (ITOF) V21/F1: A Fundamental Reassignment Law for Time-Attributed Phenomena under Invariant Ordered Succession develops the first Foundation Series extension of ITOF after the ontological assignment closure established in V20. The work does not treat time as a physical substance, force, field, causal agency, measurable material quantity, or active organizer of phenomena. Instead, it preserves time as invariant prior--subsequent ordered succession by which distinguishable realized stages are described as successive. The central temporal assignment is: T_ITOF = (S, ≺) where S denotes distinguishable realized stages and ≺ denotes the invariant prior--subsequent ordering relation. The corresponding exclusion is that T_ITOF is not an agency, influence, physical determinant, or causal operator. Time describes prior--subsequent succession; it does not produce, arrange, regulate, organize, or physically cause the phenomena described through that succession. The central aim of V21/F1 is to examine phenomena commonly attributed to time and reassign their explanatory burden to the physical, biological, observational, cognitive, measurement, signal-propagation, or modeling determinants that actually produce, condition, record, represent, or interpret them. The general reassignment law is: M_A(Z)|T_ITOF = Φ_A^Z(D_A(Z)) with the exclusion: T_ITOF ∉ D_A(Z) where M_A(Z) denotes the manifestation of a time-attributed phenomenon Z in a selected system A, D_A(Z) denotes the determinant subset responsible for that manifestation, and T_ITOF is explicitly excluded from cause, organizer, influence, and determinant status. The framework is applied across multiple domains: physical change, causality, failure, growth, healing, adaptation, evolution, cognition, memory, clocks, measurement, records, astronomical observation, light propagation, and relativistic interpretation. In each case, the work preserves the reality of the phenomenon while rejecting ontological transfer to time. Change remains assigned to system structure, physical influences, system-mediated influences, interaction processes, resistance, biological support, cognitive organization, measurement representation, observational record, signal propagation, or model structure, not to time itself. A central clarification concerns astronomical observation. Light is treated as a carrier of physical records associated with source events, not as a carrier of time. For a distant star S_star and an Earth observer A_Earth, the observational chain is represented as: E_i -> R_gamma(E_i) -> O_i where E_i is a source event, R_gamma(E_i) is a light-borne record associated with that event, and O_i is the corresponding observation. Propagation offsets affect observational access: O_2 - O_1 = (E_2 - E_1) + (Π_2 - Π_1) but they do not imply separate ontological successions of change for the star and Earth. If the propagation offset is common, stable, or corrected, the received observational separation preserves the source succession interval: Π_2 = Π_1 => O_2 - O_1 = E_2 - E_1 Thus, the relevant point is not how long the first light record required to reach Earth, even if the distance is millions or billions of light-years. The relevant point is the ordered separation between successive light-borne records. If a stellar change occurs over days, weeks, months, or years at the source, the corresponding records are received on Earth with the same interval after the first observation, subject to propagation-offset correction. Light carries records associated with realized stellar events; it does not carry the star's time, and it does not divide invariant prior--subsequent succession into distinct ontological successions. V21/F1 also reinterprets clocks and measurement systems. A clock is treated as a physical system that symbolically represents a selected regular process; it does not measure time itself. Clock drift, clock correction, clock synchronization, and relativistic correction are assigned to clock-system behavior, measurement geometry, model structure, signal coordination, and physical-realization conditions. Operational success does not by itself establish temporal ontology: Success(G_meas, G_geom, M_model) ⇏ δT_ITOF ≠ 0 The conclusion of the work is that time-attributed phenomena are real, but their explanation should not be transferred to time unless time is first shown to possess physical influence-character. Within ITOF, time describes invariant prior--subsequent succession among realized phenomena; it does not produce, arrange, regulate, organize, or physically cause those phenomena.
