CACAS provenance and reproducibility assets for a reference-corpus affinity metric study

This archive contains the provenance, reproducibility, and manuscript-support assets for the CACAS reference-corpus affinity metric study. It includes the manuscript copy, analysis scripts, result JSON files, final figure assets, verified-main-corpus manifest, reconstructed EU-woodcut provenance table, license summary, and diagnostic contact sheets. The package is intentionally conservative about image redistribution. It does not claim to be a legal authorization certificate and does not redistribute raw third-party source images. Instead, it records source URLs, public-domain or license metadata where available, provenance status, and review notes needed to audit the reference corpus used in the study. The 22 EU-woodcut pilot negatives are mapped to Commons or BHL source URLs and public-domain metadata through the original URL-hash naming rule. The archive is intended to support reproducibility, provenance review, and manuscript evaluation for the P4 CACAS study.
