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 NimbleOptions.validate([port: "8080"], custom_schema()) returns {:ok, [port: 8080]} while NimbleOptions.validate([port: :bad], custom_schema()) returns {:error, %NimbleOptions.ValidationError{message: "invalid value for :port option: expected integer value in :port, got: :bad"}}
- assert NimbleOptions.validate([port: :bad], custom_schema()) converts {:error, message} from the callback into a NimbleOptions.ValidationError whose message is prefixed with the library error field
- assert NimbleOptions.validate([port: "8080"], invalid_schema()) raises RuntimeError because the callback returns a non-conforming value
