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. matchProperty returns canonical property name when given a canonical property name directly
  2. matchProperty resolves short property aliases to their canonical ECMAScript property names
  3. matchProperty resolves binary property aliases to their canonical ECMAScript property names
  4. matchProperty throws an Error with Unknown property message when given an unknown property name
  5. matchProperty enforces strict case-sensitivity and throws an Error for incorrect casing
