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
- expect(val).to.equal and expect(val).to.be.a validate value equality and runtime type checking
- expect(obj).to.deep.equal validates structural equality across nested objects and arrays
- expect(num).to.be.at.least and expect(num).to.be.at.most validate inclusive numeric boundaries
- expect(col).to.include and expect(col).to.have.lengthOf verify collection containment and size
- expect(obj).to.have.property verifies property existence and chaining assertions on property values
- expect(fn).to.throw asserts exception thrown matching constructor or pattern and throws AssertionError on failure
