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
- traverse is exported as a function with helper utilities (explode, hasType, cheap, clearNode)
- traverse walks AST nodes and triggers visitor callbacks for specific node types such as Identifier and FunctionDeclaration
- traverse executes enter and exit lifecycle hooks in correct order for AST nodes
- traverse supports path.scope binding inspection and scope-level symbol renaming
- traverse supports path.skip to bypass child node traversal and path.stop to halt traversal
- traverse passes custom visitor state and context objects across AST nodes
- traverse supports AST mutation with path.remove and path.replaceWith
- traverse.hasType quickly detects existence of AST node types without full traversal
- traverse.explode normalizes multi-type visitor keys into exploded visitor maps
- traverse.cheap iterates over all AST nodes with a simple callback function
- visitors.merge combines multiple visitor definitions into a single visitor map
- traverse exports NodePath and Scope constructor classes
