Evidence claims:
- [sourced_fact] Spec README header lists status 'Complete, Ratified by the Khronos Group', depends on glTF 2.0, and defines kernel (only 'ellipse'), colorSpace, projection and sortingMethod properties on a mesh primitive. · locator: Status; Extending Mesh Primitives · source: https://github.com/KhronosGroup/glTF/blob/main/extensions/2.0/Khronos/KHR_gaussian_splatting/README.md
- [upstream_claim] Khronos announced the extension as a release candidate on 3 Feb 2026 (secondary reporting; ratified status above is read from the spec README as of the check date). · locator: Khronos news item · source: https://www.khronos.org/news/permalink/khronos-announces-gltf-gaussian-splatting-extension
- [sourced_fact] Repository LICENSE.adoc maps specification markup documents to CC-BY-4.0 and scripts/build tooling to Apache-2.0. · locator: LICENSE.adoc header · source: https://github.com/KhronosGroup/glTF/blob/main/LICENSE.adoc
- [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.
