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. Specificity.calculate parses single and comma-separated CSS selectors returning an array of Specificity instances
  2. Specificity instance exposes a b c component getters representing ID class and type weights
  3. Specificity instance provides toArray toObject toString and toJSON representation methods
  4. Specificity instance throws error when attempting to mutate component weights directly
  5. Specificity instances support comparison via isLessThan isGreaterThan and isEqualTo methods
