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. Option instantiates command-line option definitions with flags, description, and argument requirement flags
  2. Option.choices restricts allowed option values and throws commander.invalidArgument when an invalid choice is provided
  3. Option.default sets a fallback default value for options when omitted
  4. Option.argParser transforms option values and validates syntax with custom parser functions or InvalidArgumentError
  5. Option.env configures environment variable fallback when an option is not supplied on the command line
  6. Option.makeOptionMandatory enforces required presence of the option throwing commander.missingMandatoryOptionValue when omitted
  7. Option.conflicts defines mutually exclusive options throwing commander.conflictingOption when both are specified
  8. Option.implies automatically sets additional option values when the option is present
