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.identifier creates an Identifier AST node with the specified name string and type 'Identifier'
  2. types.isIdentifier returns true for Identifier nodes with optional name matching and false for non-Identifier nodes
  3. types.assertIdentifier succeeds for valid Identifier nodes and throws an Error for non-Identifier nodes
  4. types.isValidIdentifier correctly validates JavaScript identifier names
  5. Identifier nodes created with types.identifier integrate into larger AST constructs like VariableDeclarator and MemberExpression
  6. types.cloneNode produces an independent equivalent copy of an Identifier node
