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
- Root export returns the built-in Error constructor reference
- es-errors/eval subpath exports the built-in EvalError constructor reference
- es-errors/range subpath exports the built-in RangeError constructor reference
- es-errors/ref subpath exports the built-in ReferenceError constructor reference
- es-errors/syntax subpath exports the built-in SyntaxError constructor reference
- es-errors/type subpath exports the built-in TypeError constructor reference
- es-errors/uri subpath exports the built-in URIError constructor reference
- Constructed error instances inherit from Error and their specific constructor with expected name and message properties
- Constructors called as functions return valid error instances
- getErrorConstructor routes string identifiers to corresponding Error constructors
- createError constructs error instances matching expected constructors and messages
