Can I treat the c2pa-rs test images and clips (earth_apollo17.jpg, mars.webp, Big Buck Bunny clip, sample1.*) as covered by the repository's MIT/Apache licence?

The c2pa-rs licences cover the crate's software (MIT and Apache-2.0, dual) and the README warns that some components carry different terms. Nothing beside the test fixtures states their origin or terms, the published crate excludes tests/fixtures, and the project's own contributions note calls third-party test images something that need not be in the SDK while wishing for public-domain replacements. Treat the images and clips as unlicensed for reuse until their origin is established elsewhere. Curator qualifications: Repository text read 2026-10-22; no fixture downloaded or reused. Media rights unstated (hold); third-party works such as Big Buck Bunny may carry their own public licence, not checked here. Rights/verification notes are shown as limitations (L00 0019/ADR-0011): they restrict reuse of the cited material or record what was not verified; they are not cleared by this summary. Limitations: Repository text read 2026-10-22; no fixture downloaded or reused. [component_reuse_restriction] Eligible as rights hold; T20/T16 test-media reuse caution. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
