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
- matchProperty returns canonical property name when given a canonical property name directly
- matchProperty resolves short property aliases to their canonical ECMAScript property names
- matchProperty resolves binary property aliases to their canonical ECMAScript property names
- matchProperty throws an Error with Unknown property message when given an unknown property name
- matchProperty enforces strict case-sensitivity and throws an Error for incorrect casing
