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
- PIL.ImageStat.Stat computes per-band pixel count, extrema, sum, and sum of squares for an image.
- PIL.ImageStat.Stat calculates mean, root mean square, variance, and standard deviation statistical metrics per channel.
- PIL.ImageStat.Stat accepts a binary or grayscale mask to restrict statistical evaluation to non-zero regions.
- PIL.ImageStat.Stat can be instantiated from an image histogram list directly.
