A Testable Framework for Dark Matter Phenomenology via Coherence Dilution and Partial Actualisation

A Testable Framework for Dark Matter Phenomenology via Coherence Dilution and Partial Actualisation Complete Theoretical Formalism and Reproducible Numerical Implementation Protocol Description This chapter presents an original and self-contained theoretical framework addressing dark matter phenomenology through the dynamics of cosmological coherence dilution and partial actualisation. It is conceived as an independent scientific contribution and does not replace, supersede, or revise any previously published chapter in the author’s corpus. The approach departs deliberately from particle-centric dark matter models. No new particle species, forces, or ad hoc interaction terms are introduced. Instead, dark matter effects are examined as an emergent phenomenology associated with spacetime regions where the coherence scalar remains strictly positive but subcritical. In this regime, gravitational interaction persists while electromagnetic and baryonic manifestations remain suppressed. The framework is constructed as a minimal extension of the existing coherence formalism developed in earlier chapters, without introducing new ontological primitives or modifying previously validated effective dynamics. Conceptual terms such as potentiality, actualisation, or corruption are used exclusively as interpretative (Level A) language. All physical claims, derivations, and predictions are formulated at the operational (Level B) or falsifiable (Level C) level and remain independent of ontological interpretation. Three non-exclusive regimes are analysed: partial actualisation producing gravitational mass without electromagnetic coupling, coherence dilution and structural degradation yielding long-lived non-luminous mass distributions, non-populated geometric support in which spacetime curvature persists without particle condensation. The chapter provides: a complete and explicit theoretical formalism written in plain-text equations, linear stability and consistency checks, a fully specified and reproducible numerical implementation protocol (Boltzmann and N-body compatible), parameter ranges, pseudo-algorithms, and validation criteria, quantitative, falsifiable predictions linked to current and near-future observational programmes. This work does not claim to solve the dark matter problem exhaustively. Its objective is narrower and methodologically rigorous: to demonstrate that dark matter phenomenology can be embedded consistently within a coherence-based cosmological framework without contradiction, parameter inflation, or loss of falsifiability. Acceptance and rejection criteria are stated explicitly. The framework is therefore testable, refutable, and suitable for independent verification.
