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
- createError(status, message) creates an HttpError instance with status, statusCode, name, message, and expose (true for 4xx, false for 5xx)
- createError(status, properties) and createError(status, message, properties) attach custom properties and headers to the error
- createError(error) and createError(status, error, properties) extend existing Error instances without altering prototype inheritance
- createError[code] and createError[name] direct constructors instantiate specific HttpError subclasses with correct prototypes
- createError.HttpError abstract base class throws TypeError when directly instantiated
- createError.isHttpError(val) correctly identifies HttpError instances and duck-typed error objects while rejecting plain objects and primitives
- createError throws TypeError for unsupported argument types and falls back to status 500 for unknown status numbers
