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

Contract

  1. DEFAULT_OPTIONS exposes baseline formatting configuration with standard defaults
  2. getDefaultOptions returns a clone matching DEFAULT_OPTIONS
  3. isValidOptionKey validates option keys against DEFAULT_OPTIONS properties
  4. formatValue formats objects using default two-space indentation and properties
  5. formatValue supports custom option overrides including min and indent
  6. formatValue throws an error when unknown option keys not in DEFAULT_OPTIONS are provided
  7. formatValue respects the default callToJSON option
