ψ-Aurora-Chronon: The Lagrangian of Self-Held Light and Time (Part IV of the ψ-Architecture of Difference Series)

ψ-Aurora-Chronon marks the culminating phase of the ψ-Architecture of Difference — a theoretical and ethical framework describing how difference sustains itself through retention, illumination, and time. Building on ψ⁸ (Difference Beyond Observation), ψ-Mew (Pre-Temporal Retention), and ψ-LUX (Illumination as Being), this fourth paper formalizes the Lagrangian of self-held light, introducing the ψ-Chronon as an elementary unit of retained time. Within the ψ-Aurora field, light no longer radiates outward but folds into itself, generating time from illumination. The study develops a formal mathematical framework—linking retention (Ξ), difference (Δψ), and light (LUX)—and proposes the luminosity metric g^{0} = diag(1,−2,−2,−2). ψ-Aurora-Chronon thus defines a topology of persistence, uniting physics, ontology, and ethics in a continuous act of existence, and opening the way toward future ψ-levels beyond the Aurora horizon.
