This record contains the data, code, result tables, figures, and supplementary material for the study “How Much Does Corpus Choice Change Dependency-Distance Estimates?”. The archive includes derived analysis data, sentence-level dependency-distance metrics, treebank inclusion and exclusion records, manual provenance/comparability review tables, analysis scripts, configuration files, reproducibility tests, final result tables, figures, model/audit outputs, and the supplementary material submitted with the article. The raw corpora are public, versioned third-party resources from Universal Dependencies 2.18 and Glottolog CLDF 5.3. They are not redistributed in this archive because they are large and governed by their original license terms. Exact source URLs, versions, checksums, release dates, and retrieval information are documented in the included source manifest files. The main reproducibility files are README_ZENODO.md, data/source_manifest.csv, config/analysis.yaml, scripts/, src/, data/processed/, and results/.
