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. flatted.stringify serializes circular object references without throwing TypeError
  2. flatted.stringify serializes circular array references into indexed flatted structure
  3. flatted.stringify preserves shared references across object properties
  4. flatted.stringify serializes primitive values into flatted array representation
  5. flatted.stringify supports replacer function to transform serialized values
  6. flatted.stringify supports replacer array to filter object properties
  7. flatted.stringify supports space parameter for formatted indentation
  8. flatted.stringify roundtrips through flatted.parse recovering exact circular structure and identity
