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. stringify serializes circular object references without throwing TypeError
  2. stringify preserves shared references across multiple branches of a data structure
  3. stringify transforms property values when provided a replacer function
  4. stringify filters object properties when provided a replacer array of property names
  5. stringify formats output with indentation when space argument is specified as number or string
  6. stringify invokes custom toJSON method on objects during serialization
  7. stringify serializes primitives, arrays, and flatted parses them back preserving values
  8. cloneCircular helper performs deep clone preserving circular reference graph
