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. ArgumentParser parses positional and optional arguments with default values and type conversion
  2. ArgumentParser supports flag actions including store_true, store_false, append, and count
  3. ArgumentParser supports nargs to capture multiple values into an array
  4. ArgumentParser accepts custom type conversion functions
  5. ArgumentParser format_help and format_usage return formatted CLI documentation
  6. BooleanOptionalAction handles --flag and --no-flag switches setting boolean values
  7. add_subparsers defines subcommands with subcommand-specific arguments and options
  8. add_mutually_exclusive_group ensures mutually exclusive flags are configured and parsed
