Appendix TIM — The Mediating Layer of Temporal Structure

Appendix TIM presents a provisional proposal that redefines time not as a single axis but as a four-quadrant structure. Through the two axes of spatial-constraint dependence / phase dominance and reversibility / irreversibility, time is decomposed into four distinct domains. TIM is positioned as a mediating layer between Paper D1 and Paper D2, making visible the temporal coordinate system that connects QIII (Reversible × Phase-Dominant Time) and QIV (Irreversible × Phase-Dominant Time). It does not perform formalization or present a final theory of time; rather, it provides a structural hypothesis and a reference coordinate system for future D-series papers. It is published as a paired Japanese–English edition. Contact: laboratory@dualbind.com License: CC BY 4.0
