Shared References Weaken Pairwise Confidence More Than Rank Order in ECOTOX Chemical Prioritization — Reproducibility Package

This reproducibility package accompanies the study “Shared References Weaken Pairwise Confidence More Than Rank Order in ECOTOX Chemical Prioritization.” It contains analysis-ready freshwater-fish and Daphnia data, analysis scripts, source-structure summaries, reference-aware uncertainty and pairwise-decision outputs, publication-vintage and concentration-scale sensitivity results, figure source data, and a 48-chemical row-level external-document audit. The upstream U.S. EPA ECOTOX snapshot is not redistributed; its public source URL, release information, file size, and SHA-256 checksum are provided for provenance.
