RDCC - Dualistic Extensions III Fixpoints, Light Speed, and the Limits of Sectoral Description (Conceptual Companion)

This document is part of the Relaxation-Driven Cyclic Cosmology (RDCC) research ecosystem and belongs to the conceptual companion series Dualistic Extensions. It explores the relationship between global CPT-symmetric fixpoints and the speed of light as a sectoral coherence boundary. Within RDCC, light speed is interpreted not as a fundamental dynamical substance, but as a structural limit emerging from time-directed projection in a relaxation-driven universe. The work is interpretative and non-predictive in nature. It does not propose new dynamics or modifications to established physical laws, but offers a conceptual framework connecting symmetry restoration, causal limits, and sectoral description. This upload is intended as a philosophical–structural companion to the core RDCC framework.
