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
- BufferGeometry.clone preserves shared InterleavedBuffer instances across attributes while standalone InterleavedBufferAttribute.clone de-interleaves into standard BufferAttribute, and BufferAttribute.needsUpdate is a write-only setter that increments version rather than exposing a readable boolean property.
- BufferGeometry.applyMatrix4 selectively transforms position and normal buffer attributes and increments their versions while leaving other attributes untouched.
- BufferGeometry.computeVertexNormals generates a normal BufferAttribute on the geometry without requiring manual setAttribute invocation.
- Direct dictionary assignment to BufferGeometry.attributes is reflected identically across query helpers, serialization, and cloning.
