Reproducibility archive for "A quasi-decadal pulse linking geomagnetic pole drift, Earth rotation, and global temperature" (1981-2024)

This record is the reproducibility archive for a manuscript analyzing a quasi-decadal bridge linking geomagnetic pole drift, Earth rotation, ocean heat content, and global temperature over 1981-2024. It contains the retained derived datasets, canonical Python workflows, companion MATLAB reproducibility materials, regenerated outputs, appendix-specific reproducibility bundles, and no-code audit materials used to verify the reported results. The archive is intended as a functional reproducibility package rather than an editorial manuscript-source package.
