Reproducible likelihood pipeline for reactor neutrino phase-correction analysis (Daya Bay + KamLAND + JUNO-like)

This repository contains the fully reproducible likelihood and parameter-scan pipeline used in the phenomenological analysis of baseline- and energy-dependent phase corrections in reactor neutrino oscillations.

The pipeline implements:

• Daya Bay near–far spectral-ratio likelihood fits  
• KamLAND covariance-matrix spectral fits  
• One-parameter and multi-parameter phase-correction scans  
• Profile-likelihood construction with nuisance-parameter profiling  
• Global likelihood combination  
• Automated generation of figures and tables used in the manuscript  

The Daya Bay and KamLAND inputs are based on publicly released experimental spectral data products.

The JUNO-like configuration included in the pipeline is a sensitivity-style simulation with multi-baseline averaging and detector-response smearing. It is not based on real JUNO data.

All numerical results, χ² profiles, confidence intervals, tables, and figures are produced directly by this pipeline without manual post-processing.

This software is intended for reproducible research and independent verification of the analysis results reported in the associated paper.
