This record contains the manuscript and supporting data for the study“Emergence of Discrete Energy Scaling in a Nonlinear Triangular Collective Oscillator”. The work introduces a minimal nonlinear classical dynamical model composed of threecoupled oscillators arranged in a triangular topology. Through extensive numericalsimulations, the model exhibits robust hydrogen-like energy scaling emerging fromcollective vibrational dynamics, without invoking quantization rules or Coulomb potentials. The archive includes the full manuscript, a complete dataset of 500 numerical simulations,and the reference simulation code used to generate the results. All data and simulationsare fully reproducible.
