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. callExpression constructs a CallExpression AST node with the specified callee and arguments array
  2. callExpression supports MemberExpression callee for method calls
  3. callExpression supports SpreadElement arguments
  4. isCallExpression correctly validates CallExpression nodes against other AST node types
  5. assertCallExpression asserts that an AST node is a CallExpression and throws on mismatch
