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
- numpy.zeros, numpy.ones, and numpy.full allocate ndarrays with specified shapes, dtypes, and fill values.
- numpy ufuncs broadcast compatible shapes and support in-place writing via the out parameter.
- numpy.sum and numpy.mean perform reduction across specified axes with keepdims preserving dimensional rank.
- numpy.reshape and ndarray.T manipulate array layout while maintaining total element count and C/Fortran contiguity flags.
- numpy.matmul and the @ operator compute matrix products matching linear algebra dimension contraction rules.
- numpy.linalg.solve computes exact solutions to linear matrix systems AX = B.
- numpy.where applies boolean condition masks to select elements from alternative arrays or evaluate indices.
