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
- In Commander 10, a leading-space argument signature is not ignored, so parsing `['node', 'app', 'only']` with `new Command().arguments(' <required> [optional]')` throws `commander.missingArgument` and does not accept a single positional argument.
- assert.equal(error.code, 'commander.missingArgument')
- assert.match(error.message, /missing required argument/)
