This paper presents a falsifiable reformulation of electroweak coupling using Chronos Theory, where time is modeled as a structured curvature field. Leptons are positioned within discrete curvature bands, and their coupling strength to the electroweak field is governed by their proximity to a defined curvature resonance threshold (nEW ≈ −20.18). This geometric alignment naturally replaces the Standard Model's arbitrary Yukawa couplings with a recursive, quantized mechanism. The model predicts measurable coupling ratios, mass generation, and decay behaviors based entirely on band displacement. Additionally, it provides a curvature-based model for neutrino oscillation that replaces Δm² with time-curvature tuning.
