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.

- which(cmd) resolves to executable path on PATH
- which.sync(cmd) synchronously returns executable path
- which.sync(cmd, { nothrow: true }) returns null when executable is not found
- which(cmd) rejects with ENOENT when executable is not found
