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.

HOW- Goal
- WebGLRenderer requires WebGL 2, exposes read-only WebGLCoordinateSystem, syncs outputColorSpace to WebGL context properties, gates reversedDepthBuffer on EXT_clip_control, and scales drawing buffer dimensions by pixelRatio.

Contract
- WebGLRenderer throws an explicit error when initialized with a WebGLRenderingContext (WebGL 1), requires WebGL 2, and exposes a read-only coordinateSystem returning WebGLCoordinateSystem (2000).
- outputColorSpace defaults to SRGBColorSpace ('srgb') and setting it synchronizes drawingBufferColorSpace and unpackColorSpace on the underlying WebGL context.
- reversedDepthBuffer requires the EXT_clip_control extension to activate, invoking clipControlEXT and otherwise falling back to false on capabilities.
- getClearAlpha() defaults to 0 when alpha is enabled in renderer parameters or WebGL context attributes, and defaults to 1 when alpha is disabled.
- setPixelRatio scales canvas physical dimensions and getDrawingBufferSize by the ratio while getSize reports logical dimensions and setSize updates style properties.
