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.MemfdCreate creates an anonymous in-memory file descriptor with close-on-exec flag
- unix.Gettid retrieves the caller thread ID matching a positive integer
- unix.Getpgrp retrieves process group identifier matching a positive integer
- unix.InotifyInit1 initializes an inotify instance returning a valid file descriptor
