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
- transforms ES6 class declarations and method definitions into ES5 constructor functions with prototype methods
- enforces runtime constructor call checks to throw TypeError when a class is invoked without new
- transforms class inheritance with extends, super calls, and prototype chain wiring
- transforms static methods and getter/setter property descriptors
