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. CommanderError instantiates with exitCode, code, and message properties representing CLI execution errors
  2. exitOverride causes Command parsing errors such as unknown command or missing mandatory option to throw CommanderError instances
  3. exitOverride throws CommanderError with exitCode 0 and code commander.version or commander.helpDisplayed for version and help triggers
  4. CommanderError instances inherit from the standard JavaScript Error class and can be caught with try-catch blocks
  5. Custom exitOverride error handlers can inspect and rethrow or customize CommanderError instances
