Evidence claims:
- [upstream_claim] README: OFX is an image processing plug-in standard; points to openfx.readthedocs.io (Reference, Programming Guide By Example) and build instructions. · locator: README, header links · source: https://github.com/AcademySoftwareFoundation/openfx
- [sourced_fact] Documentation says the manual is maintained largely by volunteers and is licensed under CC-BY 4.0; the licence statement applies to the manual not the software. · locator: docs landing page, footer · source: https://openfx.readthedocs.io/en/latest/
- [sourced_fact] GitHub metadata: BSD-3-Clause, not archived, last push 2026-10-15. · locator: repository metadata · source: https://github.com/AcademySoftwareFoundation/openfx
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.
