A Structural Companion to Relaxation-Driven Cyclic Cosmology

This document is a conceptual and structural companion to the Relaxation-Driven Cyclic Cosmology (RDCC) framework. It does not propose a new dynamical cosmological model, nor does it attempt to compete with or replace established approaches such as ΛCDM. Instead, it preserves and articulates the interpretative, ontological, and symmetry-based ideas that motivated the development of RDCC. The text explores themes such as CPT symmetry, sectoral time orientation, duality, and the reinterpretation of fundamental constants (e.g. ε, π, i) as structural markers rather than purely dynamical parameters. It also offers a non-standard perspective on quantum entanglement as a consequence of sectoral projection from a globally non-separable, timeless state. This work is intended as a reflective and exploratory resource for readers interested in the conceptual foundations of cyclic cosmology, symmetry principles, and the limits of sectoral physical description. It serves as a companion and memory space for ideas that may guide future formal or mathematical developments, without making empirical claims or predictive assertions. The document is released as an independent, citable record of conceptual reasoning and is open to reinterpretation, critique, or extension.
