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. program.args remains empty when an optional positional argument with a default value is omitted, because default argument values are populated into program.processedArgs and action parameters rather than program.args.
  2. omitted defaulted argument is absent from program.args when partial arguments are supplied
  3. variadic omitted argument without an explicit default defaults to an empty Array rather than undefined
  4. custom coerce parser is bypassed for default values when options or arguments are omitted
  5. program.opts populates defaults for omitted options while program.args does not populate defaults for omitted arguments
