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. parse deserializes flatted string with circular object reference into circular object graph
  2. parse deserializes flatted string with circular array reference into circular array
  3. parse restores shared object references preserving identity without duplication
  4. parse deserializes primitive values serialized with flatted
  5. parse deserializes nested objects and arrays correctly
  6. parse applies reviver function to transform parsed values
  7. parse throws SyntaxError when input contains invalid JSON syntax
  8. parse throws TypeError when input is not a flatted serialized array structure
