Version 1.1.0 Update Summary This release reclassifies the paper as foundational within the Temporal–Density Framework (TDFT). While the technical content remains unchanged, the work is now formally positioned as part of the developmental and structural archive leading to the canonical formulation of the framework. The complete and authoritative presentation of TDFT is contained in the three-volume series Dimensionless Unification and Empirical Predictions, Unified Origins of Matter, Dark Matter, and Horizon Geometry, and Entropy Gradients, Cosmic Structure, and Large-Scale Dynamics, which supersede the present work and should be cited in preference where the full theory is required. No substantive corrections to the analysis or results are introduced in this update. Version 1.0.1 — Update Notes Minor content revision of the original release (v1.0).This update adds the Testability Outlook section and refined “Notes for Further Development,” completing the empirical roadmap of Volume 2.The document now incorporates final structural polish and closing reflection, establishing Volume 2 as the definitive dimensionless formulation of the Temporal–Density Framework. Scientific content and equations remain consistent with the original release; metadata and layout have been standardised for series continuity.The canonical DOI for citation remains 10.5281/zenodo.17582953.

This paper forms part of the foundational archive of the Temporal–Density Framework (TDFT). It develops an early or specialised aspect of the framework but is not intended as a standalone or canonical reference. The complete and authoritative formulation of the Temporal–Density Framework is presented in the three-volume series: • Volume I — Dimensionless Unification and Empirical PredictionsDOI: 10.5281/zenodo.17597722 • Volume II — Unified Origins of Matter, Dark Matter, and Horizon GeometryDOI: 10.5281/zenodo.17666466 • Volume III — Entropy Gradients, Cosmic Structure, and Large-Scale DynamicsDOI: 10.5281/zenodo.17716678 These volumes supersede the present work and should be cited in preference where the full framework, definitions, derivations, and predictions are required. This paper is retained for archival completeness and for readers interested in the developmental trajectory, intermediate derivations, or specific structural components that informed the final theory.
