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.

Contract
- types is exported by @babel/core as an object containing AST builder and validator utilities
- types.identifier creates an Identifier AST node and types.isIdentifier validates it
- types.binaryExpression creates a BinaryExpression AST node combining operator and operand nodes
- types.variableDeclaration creates a variable declaration statement containing variable declarators
- types.assertIdentifier succeeds on valid Identifier nodes and throws TypeError on invalid nodes
- types.isNodesEquivalent returns true for structurally equivalent AST nodes and false for different nodes
- types.cloneNode performs a deep clone of AST nodes preserving structure and properties
- types.callExpression creates a function call AST node with callee and arguments
