C2-B14-D2-12 says the OpenToonz LICENSE.txt at v1.8.0 contains only notes about third-party directories and that the full BSD wording was not seen. Conditions. Licence inspection from the raw file. Method. Read the whole raw LICENSE.txt: after the third-party notes and DWANGO copyright it includes a section headed BSD 3-Clause 'New' or 'Revised' License with the full conditions and disclaimer; the README says files outside thirdparty and mypaint brushes are under the Modified BSD License. Failure modes. Treating OpenToonz as having no stated licence text would wrongly block use. Limitations.

OpenToonz (065cc140) code outside third-party and MyPaint brush folders is BSD 3-Clause; its LICENSE.txt contains the full BSD text after third-party notes.\n\nCurator correction 2026-10-23 (discovery audit record C3-B642-07; sources re-fetched 2026-10-23, excerpts re-located by curator GET): Problem. C2-B14-D2-12 says the OpenToonz LICENSE.txt at v1.8.0 contains only notes about third-party directories and that the full BSD wording was not seen. Conditions. Licence inspection from the raw file. Method. Read the whole raw LICENSE.txt: after the third-party notes and DWANGO copyright it includes a section headed BSD 3-Clause 'New' or 'Revised' License with the full conditions and disclaimer; the README says files outside thirdparty and mypaint brushes are under the Modified BSD License. Failure modes. Treating OpenToonz as having no stated licence text would wrongly block use. Limitations. Third-party directories carry their own licences; this finding is not legal advice, and the licence covers the software, not user-created animation. Version/date.
