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
- ParserIterator yields parsed items until failure then yields None
- calling next() repeatedly on exhausted ParserIterator returns None without draining internal state
- calling finish() on exhausted ParserIterator succeeds with remaining stream slice instead of panicking on None unwrap
- calling finish() on cut error preserves and returns the ModalResult cut error
