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
- lowercaseKeys transforms all own enumerable property keys of an object to lowercase
- lowercaseKeys preserves the associated values of transformed keys
- lowercaseKeys returns a shallow copy and does not mutate the source object
- lowercaseKeys overwrites earlier properties if multiple keys collide when lowercased
- lowercaseKeys returns an empty object when passed an empty object
