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
- isatty.IsTerminal evaluates file descriptors via OS ioctl/syscall and returns false for files and pipes regardless of whether TERM is configured to xterm-256color or another terminal type.
- isatty.IsTerminal returns false cleanly without panicking or returning an error when passed invalid or closed file descriptors.
- isatty.IsCygwinTerminal on non-Windows platforms returns false unconditionally for all descriptors regardless of CYGWIN, MSYSTEM, or TERM environment variables.
