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
- Texture.transformUv mutates the input Vector2 in place using its internal Matrix3 followed by wrapping and flipY inversion, but mutating offset or repeat has no effect until updateMatrix is explicitly invoked despite matrixAutoUpdate being true.
- Texture.transformUv applies RepeatWrapping, ClampToEdgeWrapping, and MirroredRepeatWrapping to out-of-bounds UV coordinates before applying flipY inversion.
- Setting texture mapping to non-UV modes like CubeReflectionMapping causes transformUv to return immediately without matrix transformation, wrapping, or flipY modification.
- Rotation around a configured center in Texture.updateMatrix properly transforms coordinates in accordance with the UV transform matrix.
