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. estraverse.Syntax is exported as an object mapping AST node type names to identical string constants
  2. Syntax defines core ESTree declarations and statements including Program, FunctionDeclaration, and VariableDeclaration
  3. Syntax defines core ESTree expressions and literals including BinaryExpression, CallExpression, MemberExpression, Identifier, and Literal
  4. Syntax defines modern ES6+ node types including ArrowFunctionExpression, ClassDeclaration, TemplateLiteral, and AwaitExpression
  5. Syntax constants match node.type values when traversing an AST with estraverse.traverse
  6. Syntax constants enable filtering and selective transformation of AST nodes with estraverse.replace
