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.variableDeclaration creates a VariableDeclaration AST node with the specified kind and declarations array
  2. types.variableDeclaration supports var, let, and const declaration kinds with multiple declarators
  3. types.isVariableDeclaration returns true for VariableDeclaration nodes with optional kind matching and false for non-VariableDeclaration nodes
  4. types.assertVariableDeclaration succeeds for valid VariableDeclaration nodes and throws an Error for non-VariableDeclaration nodes or mismatching kind
  5. VariableDeclaration nodes integrate into statement contexts such as Program body, BlockStatement body, and ForStatement initialization
  6. types.cloneNode produces an independent equivalent copy of a VariableDeclaration node
