Code, analysis log and derived data for "Temporal leakage in annual satellite embeddings inflates landslide susceptibility assessments"

This record accompanies the manuscript "Temporal leakage in annual satellite embeddings inflates landslide susceptibility assessments", submitted to Journal of Remote Sensing (earlier version: EarthArXiv preprint https://doi.org/10.31223/X5RB93). Annual satellite embeddings such as AlphaEarth Foundations and TESSERA summarize a calendar year, so the layer of a landslide's event year can already contain post-event observations. The study audits 18 dated landslide events with paired year swaps under fixed spatial validation, adds controlled Sentinel-2 experiments with a fixed number of observation dates and a preceding-year seasonal reference, decomposes the effect by training and prediction year, compares AlphaEarth with TESSERA and annual Sentinel-2 composites, evaluates complete maps, and tests how much pre-event embeddings add beyond conventional factors and explicit landslide history. Version 2.0 adds the analyses of the journal revision (M3_zenodo_v2_20261101.zip): code, locally prespecified protocols and run manifests, per-sample predictions, optical date selections and scene metadata, radiometric checks, date-qualified historical records and control samples, within-fold AUC statistics, the patch-missingness scan and paired CNN refits, land-cover blocks, the figures of the submitted manuscript with the script that redraws them, and the public copy of the analysis log (in Chinese). An offline check (scripts/m3_v12/verify_archive.py) verifies every checksum, recomputes the revision statistics from the saved predictions and redraws the figures byte-identically. The version 1.0 archive of the original analyses (M3_zenodo_package_20261019.zip) is included unchanged.
