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.fromJSON reconstructs primitive values from serialized flatted structure
  2. flatted.fromJSON reconstructs standard objects and nested arrays without recursion
  3. flatted.fromJSON reconstructs self-referencing circular object references preserving object identity
  4. flatted.fromJSON reconstructs circular array references preserving root array identity
  5. flatted.fromJSON reconstructs mutually circular references between multiple distinct objects
  6. flatted.fromJSON preserves shared object references across distinct properties without duplication
  7. flatted.fromJSON reconstructs object graphs from raw JSON-parsed flatted representation
  8. flatted.fromJSON correctly handles empty objects and empty arrays
