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.

Case
HOW- Goal
- THREE.WebGLRenderer.capabilities.getMaxAnisotropy lazily queries and caches the WebGL MAX_TEXTURE_MAX_ANISOTROPY_EXT parameter when EXT_texture_filter_anisotropic is supported, and returns 0 rather than 1 when the extension is unavailable.

Contract
- renderer.capabilities.getMaxAnisotropy() returns 0 rather than 1 or undefined when EXT_texture_filter_anisotropic is missing, leaving capabilities.maxAnisotropy undefined.
- When EXT_texture_filter_anisotropic is available, getMaxAnisotropy() queries gl.getParameter(MAX_TEXTURE_MAX_ANISOTROPY_EXT) lazily on first invocation and caches the result for subsequent calls.
