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
- Plugin default export is a function factory asserting Babel 7 compatibility
- Plugin factory returns an object named transform-block-scoping with visitors for variable declarations and loop statements
- Plugin validates throwIfClosureRequired option to be a boolean, throwing an error otherwise
- Plugin validates tdz option to be a boolean, throwing an error otherwise
- VariableDeclaration visitor transforms block-scoped let declarations to var and moves binding to outer var scope
- VariableDeclaration visitor renames shadowed block-scoped variables when parent scope contains matching identifiers
- VariableDeclaration visitor preserves standard var declarations without modifying scope
- Module helpers instantiate the plugin, validate options, and execute variable declaration AST transformations
