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
- The default ImageOps.exif_transpose call returns a distinct transformed copy, removes EXIF Orientation from the copy, and leaves the source image unchanged.
- ImageOps.exif_transpose(..., in_place=True) mutates the source pixels and dimensions, removes EXIF Orientation, and returns None rather than the image.
- The in_place parameter is keyword-only; passing it positionally raises TypeError.
- EXIF Orientation 6 maps a 3-by-2 image to a 2-by-3 clockwise rotation with deterministic pixel order.
