Is there an official C2PA public test-file set for validators, and what licence does it state?

The C2PA public test-file repository is CC BY-SA 4.0 as a whole (share-alike applies to derived test packs) and, at this pin, its 2.2 directories hold only READMEs and .gitkeep placeholders, so no C2PA 2.2 media test pack is present there. Curator qualifications: Licence texts/pages read 2026-10-22; no test files downloaded; not legal advice. Where the actual assets live (producer reading) not re-read. Limitations: Licence texts/pages read 2026-10-22; no test files downloaded; not legal advice. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
