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. typeOf returns lowercase type name for JavaScript values including primitives, arrays, dates, maps, sets, and objects
  2. className returns constructor name for objects and null when constructor is absent or null prototype
  3. functionName returns the identifier name of named and assigned function declarations
  4. every returns true when all elements in an array, Set, or Map satisfy predicate and false otherwise
  5. valueToString converts primitives, objects, and nullish values to string representations
  6. prototypes provides safe uncurried methods on array, string, and object prototypes
  7. calledInOrder returns true when spy instances are executed in sequential order
  8. orderByFirstCall sorts an array of spy objects chronologically by their first invocation callId
