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
- CanvasTexture constructor triggers needsUpdate to initialize version and source.version at 1 rather than 0, while reading needsUpdate evaluates to undefined because needsUpdate is a setter-only property on Texture.
- Setting needsUpdate to true increments both texture.version and source.version by 1, whereas setting it to false leaves versions unchanged.
- Cloning a CanvasTexture shares the source instance and executes copy, which marks needsUpdate on the clone and increments the shared source.version.
