This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Contract
- ACESFilmicToneMapping is exported as the integer constant 4 across root and webgpu entrypoints, identifying the ACES Filmic curve in ShaderChunk and ToneMappingNode pipelines.
- Tone mapping constants distinguish NoToneMapping (0), LinearToneMapping (1), ReinhardToneMapping (2), CineonToneMapping (3), ACESFilmicToneMapping (4), CustomToneMapping (5), AgXToneMapping (6), and NeutralToneMapping (7).
- ShaderChunk tonemapping_pars_fragment defines the vec3 ACESFilmicToneMapping GLSL function applying the RRTAndODTFit curve scaled by exposure / 0.6.
- ToneMappingNode in three/webgpu and toneMapping in three/tsl accept ACESFilmicToneMapping to configure WebGPU node rendering.
- ACES Filmic curve transforms linear color through ACESInputMat and ACESOutputMat with rational polynomial fitting, clamping black to 0.0 and compressing highlights asymptotically to 1.0.
