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. types.functionDeclaration creates a FunctionDeclaration AST node with specified identifier, parameters, body, and default generator and async flags set to false
  2. types.functionDeclaration creates async and generator function declarations when async or generator flags are set to true
  3. types.functionDeclaration creates anonymous function declarations when null is provided as the identifier
  4. types.isFunctionDeclaration returns true for FunctionDeclaration nodes with optional property matching and false for non-FunctionDeclaration nodes
  5. types.assertFunctionDeclaration succeeds for valid FunctionDeclaration nodes and throws an Error for invalid or mismatching nodes
  6. FunctionDeclaration nodes integrate with parameter patterns including Identifier, AssignmentPattern, and RestElement
  7. types.cloneNode produces an independent equivalent copy of a FunctionDeclaration node
