From Informational Coherence to Regime Transitions: A Structural Continuity Note

This technical note documents the structural continuity between earlier work developed under the Informational Coherence Model (MCI) and the axiomatic framework of Regime Shift Theory (RST). No new physical assumptions, mechanisms, laws, or ontological claims are introduced. The note does not extend, revise, or reinterpret prior results. Its sole purpose is to clarify the evolution of scope and methodological level across the two frameworks, making explicit their non-competitive and non-overlapping roles. MCI operates at a descriptive and phenomenological level, addressing coherence patterns within specific regimes. RST, by contrast, operates at a second-level methodological layer, formalizing the structural conditions under which models and descriptions lose validity due to regime transitions, irreversibility, loss of comparability, or non-transitivity. This document serves exclusively as a continuity reference and historical linkage. It should not be read as a complete theoretical formulation, a unifying framework, or a proposal of new physics.
