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
- errCode attaches a string error code to an Error instance under the code property
- errCode attaches additional custom properties to an Error instance alongside the error code
- errCode accepts an object of custom properties as the second argument when code is omitted
