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
- getType is exported as a function
- getType accurately distinguishes primitive values including undefined, null, boolean, number, bigint, string, and symbol
- getType accurately distinguishes built-in objects including array, regexp, map, set, and date
- getType identifies standard functions, arrow functions, generator functions, async functions, and class constructors as function
- getType identifies plain objects and objects created with Object.create(null) as object
