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.Geteuid and unix.Getegid retrieve effective process credentials matching os.Geteuid and os.Getegid
- unix.EpollCreate1 creates an epoll instance returning a valid file descriptor
- unix.FcntlInt queries file descriptor flags verifying close-on-exec status
- unix.Eventfd creates an event wait/notify file descriptor transferring counter values
