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
- ArgumentParser constructor instantiates a command line parser with custom prog and description
- addArgument defines positional arguments and parses required positional values
- addArgument defines optional flags with default values and custom destinations
- addArgument supports type conversion such as integer and float
- addArgument supports storeTrue and storeFalse boolean actions
- addArgument enforces choices validation and calls exit on invalid values
- addArgument supports variable argument lists using nargs modifier
- parseKnownArgs parses recognized options and returns unrecognized arguments as a separate array
