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. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

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