Holographic Residual Dark Matter: A Non-Particle Origin for Cold-Dark-Matter Phenomenology

This record is a Master Working Note / Extended Framework for the Holographic Residual Dark Matter (HRDM) model. It preserves the broader conceptual and mathematical development of the framework, including the pre-geometric holographic seed, critical surface-area initialization, projection lock-in, the residual gravitational component X, CDM-like effective behavior, galaxy-scale phenomenology, and merging-cluster interpretations. This document is not intended as a concise submission-ready paper. Focused papers derived from this master note, including a shorter Paper I on the core CDM-like component, will be released as separate records. This technical preprint proposes a minimal phenomenological model in which…
