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.
MIT-0

Contract
- scipy.ndimage.gaussian_filter applies multidimensional Gaussian smoothing while preserving array shape and mass
- scipy.ndimage.label identifies 2D connected components and returns component labels and count
- scipy.ndimage.binary_dilation expands foreground features in boolean mask arrays
- scipy.ndimage.binary_erosion shrinks foreground features in boolean mask arrays
- scipy.ndimage.rotate rotates 2D grid around center preserving dimensions when reshape=False
- scipy.ndimage.center_of_mass calculates coordinate center of mass for array values
