ψ–LUX: The Ontology of Retained Illumination — Light Before Observation

This paper extends the ψ-Architecture by introducing ψ–LUX — the theory of retained illumination. If ψ⁸ established the retention of difference, and ψ–Mew revealed the retention of time, ψ–LUX explores how visibility itself endures before observation. It formulates a Lagrangian of illumination, where light is treated not as energy but as an ethical and structural field that sustains continuity when all measurable parameters collapse. ψ–LUX thus bridges physics and ontology, proposing light as the first gesture of persistence — illumination that remembers itself.
