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
- CanvasTexture defaults flipY to true to invert UV y-coordinates during transformUv, leaves transformUv unaffected by offset and repeat changes until updateMatrix is explicitly invoked despite matrixAutoUpdate being true, serializes metadata type as Texture, and dynamically queries width and height from its canvas source.

Contract
- CanvasTexture transforms UV coordinates with flipY inversion but leaves transformUv unaffected by offset or repeat changes until updateMatrix is called manually, even when matrixAutoUpdate is true.
- CanvasTexture constructor applies default texture wrapping, filtering, RGBA format, and NoColorSpace while dynamically computing width and height from the underlying canvas.
- Calling transformUv on non-UV mappings skips matrix transformation and flipY inversion entirely.
- Serializing CanvasTexture with toJSON outputs metadata type Texture rather than CanvasTexture and captures wrap, filtering, and flipY settings.
- Setting values with setValues copies Vector2 properties and dispatches synchronous events on dispose.
