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
- OptionValidator constructor initializes descriptor and formatMessage prefixes error messages with descriptor
- validateTopLevelOptions validates allowed options against TopLevelOptionShape and throws formatted error with suggestion for invalid keys
- validateBooleanOption returns given boolean value, returns defaultValue when undefined, and throws when value is not a boolean
- validateStringOption returns given string value, returns defaultValue when undefined, and throws when value is not a string
- invariant throws formatted error when condition is falsy and passes when truthy
- findSuggestion finds the candidate string with minimal Levenshtein distance
