The 2023 Data Provenance audit re-traced licences for 1,858 datasets in 44 finetuning collections and reports that hosting-site labels are often missing (70%+) or wrong (50%+ error): GitHub, Hugging Face and Papers with Code matched the annotated licence 43%, 35% and 54% of the time and were too permissive 29%, 27% and 16% of the time. The authors call their protocol a best-effort check, not legal advice. An agent should not treat a hosting-site licence label as verified.
