Reproducibility package for Diffusivity-Uniform Mean Corrections and Initial-Layer Memory in Thermochemical Reaction Systems

Reproducibility package accompanying "Diffusivity-Uniform Mean Corrections and Initial-Layer Memory in Thermochemical Reaction Systems" by Nam-Hyun Yoo, Hyojin Park, and Jinhong Yang. Corresponding author: Jinhong Yang ([e-mail]). The package contains verification programs, fixed configurations, saved numerical trajectories, tables, and four figures. It includes modal/PDE, fast-diffusion, joint-limit, and spectral-tail calculations; 72 closed-form coefficient comparisons; 32 finite-amplitude sensitivity cases; and four spatial-grid/integrator comparisons. All results are generated mathematical benchmarks; no measured material dataset or experimental calibration is included. The README gives environment versions and reproduction commands. The supplementary record publishes code and research data and does not assert journal acceptance or publication of the manuscript.
