 "claim": "UltraData-Code declares Apache-2.0 in its card YAML and ships the verbatim Apache-2.0 text as LICENSE. Its README then prohibits, in English and Chinese, the reposting and mirroring that Apache-2.0 §2 grants irrevocably. Separately, the card instructs users to comply with each source repository's licence — which L2's schema makes possible and L3's schema makes impossible, because L3 keeps the verbatim source file in raw_content and drops repo_name and relative_path.",
 "method": "Read at commit ebea626 / 86a7233 on 2026-09-18: the card YAML via the Hub API (cardData.license), README.md and README_ZH.md via /raw/main, the LICENSE blob via /resolve/main, and the two row schemas from the README's own Data Formats section, cross-checked against the feature list the datasets-server /rows endpoint returns for each config.",
