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
- assert Set#to_set with default arguments returns self instead of a new duplicate set, so mutating the result modifies the original set in-place
- assert calling to_set on a Set subclass with default klass downcasts the receiver to a base Set instead of retaining the subclass
- assert calling to_set with an explicit klass argument constructs an instance of the specified class
- assert calling Set#to_set with a block returns a newly allocated Set rather than returning self
- assert Enumerable#to_set with default klass converts any Enumerable into a base Set instance
