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
- MeshSurfaceSampler.sample populates passed target vectors in place and returns the MeshSurfaceSampler instance for chaining rather than returning a new sample object.
- Calling sample before build throws a TypeError because cumulative distribution weights are uninitialized.
- sample interpolates vertex attributes (position, normal, color, uv) across the sampled face using barycentric coordinates.
- When geometry lacks a vertex normal attribute, sample computes the geometric face normal and assigns it to targetNormal.
