Data and code for "Negative-sample hardness reveals shortcut-like dependence on dominant predictors in landslide susceptibility modeling"

This repository contains the figure-ready source data, fold-level evaluation tables, ablation summaries, statistical-test inputs, derived diagnostic summaries, scripts, metadata, and reproducibility documents supporting the manuscript “Negative-sample hardness reveals dominance-prone shortcut-like dependence in landslide susceptibility modeling”. The package supports verification of the reported numerical results, tables, figures, and statistical tests, including the negative-sample hardness gradient, mainline model performance, Road/Rain ablation diagnostics, SHAP-based interpretation summaries, susceptibility-zoning summaries, fold-alignment checks, hyperparameter robustness checks, and Supplementary Figure S3 correlation/VIF diagnostics. The raw landslide inventory with precise coordinates, unpublished local geological hazard investigation materials, original raster/vector geospatial layers, and restricted third-party data are not redistributed because of geographic sensitivity and licensing constraints. Instead, this package provides derived figure-ready tables, anonymized or summarized fold-level metrics, scripts, and final display figures needed to verify the reported results.
