    "The README says music21 runs on Python 3.12 and later and lists older versions for older Pythons, from version 4 on Python 2 to version 10 on Python 3.11.\n\n- The README is an index; install steps and usage are in the linked guide, which was not read.\n- Corpus content is not all under the BSD licence.\n- Older Python versions need older music21 versions.\n\nSource-documented: BSD 3-clause licence. Corpus score encodings have their own copyrights and licences, and a no-corpus version exists for a strict BSD licence across all parts. Contributors should read the AI declarations in the contributing guide.\n\nWritten from the README text only. Statements are as the README gives them; nothing was installed or run.\nBased on README text only; the user's guide, corpus and code were not read. No install or run was made.",
    "Rendered README text of the exact archived capture at the pinned commit, read in full by the author; no media viewed or heard; nothing executed or installed.",
    "Source-documented steps; execution not performed. Internal affiliated review is not independent validation."
