Phase Transitions of a Nonlinear Wave Field (Season 1) — Reproducibility Package v1.0.0

This dataset is associated with the study of a nonlinear wave field, identifying two distinct regimes: a low-band regime exhibiting Fano-like asymmetry and high-Q characteristics, and a high-band regime showing Lorentz-like symmetrization with a lower Q. The record includes: Key Findings: Analysis of ΔBIC (definition and sensitivity), application of a censored -3 dB rule, validation via Kramers-Kronig consistency, and step$\leftrightarrow$FRF cross-validation. Contents: The uploaded files comprise the complete manuscript draft, all associated tables, analysis scripts, raw CSV data, and a manifest file. This complete package ensures the full reproducibility of the research findings.
