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. assert stringify produces deterministic JSON string with sorted object keys regardless of key insertion order
  2. assert stringify handles nested objects and arrays deterministically
  3. assert stringify formats output with indentation when space option is provided as a number or string
  4. assert stringify supports custom key comparison function via cmp option or direct function parameter
  5. assert stringify supports replacer function and serializes objects with toJSON methods
  6. assert stringify throws TypeError on circular structures by default and replaces circular references with __cycle__ when cycles option is true
  7. assert stringify correctly serializes primitive values, null, and omits undefined or functions in objects while converting them to null in arrays
