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
- Disabling allowTrailingOptions causes option-like arguments and the double-dash separator after a positional argument to be treated as literal positional arguments in results.rest rather than being parsed or consumed.
- assert parser with allowTrailingOptions: false treats --mode and --verbose after a positional argument as literal positional arguments in rest rather than parsing them
- assert parser with allowTrailingOptions: false preserves the double-dash separator in rest rather than consuming it
- assert default parser with allowTrailingOptions: true consumes the double-dash separator and parses options normally
