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. 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.
  2. assert parser with allowTrailingOptions: false treats --mode and --verbose after a positional argument as literal positional arguments in rest rather than parsing them
  3. assert parser with allowTrailingOptions: false preserves the double-dash separator in rest rather than consuming it
  4. assert default parser with allowTrailingOptions: true consumes the double-dash separator and parses options normally
