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
- unix.Getpagesize returns a positive system memory page size in bytes
- unix.Pipe creates a unidirectional pipe returning valid non-negative file descriptors for read and write
- unix.Write writes bytes to a pipe descriptor and unix.Read reads the matching bytes back
- unix.Getpid returns the caller process ID matching os.Getpid
- unix.NsecToTimeval converts nanoseconds to Timeval and unix.TimevalToNsec accurately converts back
