Evidence claims:
- [upstream_claim] README: tools for rendering wide-gamut scene-linear data to an SDR or HDR display; OpenDRT places as much control as possible in the image author's hands; most tools available as a Nuke node and as a DCTL; JzDT described as an old and flawed experiment. · locator: README, list of transforms · source: https://github.com/jedypod/open-display-transform
- [sourced_fact] LICENSE is the GNU General Public License v3. · locator: LICENSE, header · source: https://github.com/jedypod/open-display-transform
- [sourced_fact] GitHub metadata: GPL-3.0, not archived, last push 2026-02-09. · locator: repository metadata · source: https://github.com/jedypod/open-display-transform
- [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.
