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
- unix.Write writes the entire byte buffer to a valid pipe file descriptor
- unix.Write returns n=0 and nil error when writing an empty slice
- unix.Write returns EBADF when writing to an invalid file descriptor
- unix.Write returns EBADF when writing to a closed file descriptor
- unix.Write preserves byte sequence and contents across sequential writes
- unix.Write writes successfully to a regular file descriptor opened with O_WRONLY
