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. Argument instantiates positional argument definitions with name, description, required, and variadic flags
  2. Argument.choices restricts allowed argument values and throws commander.invalidArgument when an invalid choice is provided
  3. Argument.default sets a fallback default value for optional positional arguments when omitted
  4. Argument.argParser transforms input values and validates syntax with custom parser functions or InvalidArgumentError
  5. Argument supports variadic positional arguments collecting multiple values into an array
