Abstract

fetched live from OpenAlex

Almost all software, open or closed, builds on open source software and therefore needs to comply with the license obligations of the open source code. Not knowing which licenses to comply with poses a legal danger to anyone using open source software. This article investigates the extent of inconsistencies between licenses declared by an open source project at the top level of the repository and the licenses found in the code. We analyzed a sample of 1,000 open source GitHub repositories. We find that about half of the repositories did not fully declare all licenses found in the code. Of these, approximately 10% represented a permissive vs. copyleft license mismatch. Furthermore, existing tools cannot fully identify licences. We conclude that users of open source code should not just look at the declared licenses of the open source code they intend to use, but rather examine the software to understand its actual licenses.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
