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
- concatMap(xs, fn) transforms elements by fn and concatenates resulting arrays into a flattened array
- concatMap(xs, fn) appends scalar non-array return values directly to the result array
- concatMap(xs, fn) drops elements when fn returns an empty array
- concatMap(xs, fn) provides element and 0-based index to the callback function
- concatMap(xs, fn) returns an empty array when given an empty input array
