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
- defineProperties defines non-enumerable, writable, configurable properties on target object
- defineProperties preserves existing properties when predicates are not provided or falsy
- defineProperties overwrites existing properties when predicate is boolean true and value differs
- defineProperties overwrites existing properties when predicate function returns truthy
- defineProperties does not overwrite existing properties when predicate function returns falsy
- defineProperties supports symbol keyed properties on target object
- defineProperties.supportsDescriptors is a boolean indicating descriptor support
