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.blockStatement creates a BlockStatement AST node with an array of statement nodes and directives
  2. types.blockStatement creates an empty block statement when called with an empty statements array
  3. types.isBlockStatement returns true for BlockStatement nodes with optional property matching and false for non-BlockStatement nodes
  4. types.assertBlockStatement succeeds for valid BlockStatement nodes and throws an Error for non-BlockStatement nodes
  5. BlockStatement nodes integrate as the body of control flow and function constructs such as FunctionDeclaration, IfStatement, and TryStatement
  6. types.cloneNode produces an independent equivalent copy of a BlockStatement node
