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. YAML.parseDocument parses a YAML string into a Document AST instance
  2. Document.get and Document.set retrieve and update values in the document AST
  3. Document.has checks for key existence and Document.delete removes a key
  4. Document.toJS converts the AST document into a plain JavaScript object
  5. Document.toString serializes the AST document back into a YAML string
