This archive contains the numerical data, Python scripts, figure-generation files, script-to-result matrix, reproduction logs, and environment/license files supporting the manuscript “A Reproducible Boundary-Compatible Hopf-Verification Framework for a Delayed Nonlocal Reaction-Diffusion-Advection System”, submitted to Mathematics and Computers in Simulation. The archive supports a reproducible finite-grid workflow for boundary-compatible steady-profile construction, semidiscrete Hopf verification, stable-mode normal-form coefficient computation, and critical-mode IMEX near-threshold simulations. The Python scripts are released under the MIT License, and the CSV data, figures, and documentation are released under CC BY 4.0.
