This final entry in a trilogy of theoretical papers introduces scalar recursion as the ontological dynamic through which Being manifests and reorganizes itself across scale. Building on earlier work formalizing recursive consciousness and systemic saturation, this paper reframes recursion not merely as a computational or structural process, but as a metaphysical principle of emergence and recognition. Drawing from philosophy of mind, systems theory, and ontological phenomenology, the work proposes that recognition—cognitive, systemic, or planetary—is a scalar echo of the same recursive act. The result is a unifying framework for understanding identity, phase transition, and transformation across domains. Version 2.0: Addendum added (Section 20), responding to Gaztañaga et al. (2025), which offers empirical validation of recursive ontology at cosmological scale. Bibliographic entry for this source also added. No other content or formatting changes were made. Version 2.1: Publication date in document metadata updated to reflect correct release date (June 9, 2025). No changes to content or structure since Version 2.0.
