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. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. ArgParser.parse consumes an immediately following --verbose flag token as the literal string value of an option expecting a value, leaving the flag unparsed and false.
  2. assert(results['output'] == '--verbose');
  3. assert(results['verbose'] == false);
  4. assert(results.wasParsed('verbose') == false);
