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-arrow-functions with an ArrowFunctionExpression visitor method
- ArrowFunctionExpression visitor invokes arrowFunctionToExpression with default loose options when spec option is omitted
- ArrowFunctionExpression visitor configures specCompliant transformation when spec option is true
- ArrowFunctionExpression visitor prioritizes noNewArrows compiler assumption over spec option
- ArrowFunctionExpression visitor skips transformation when node is not an arrow function expression
- Module helper simulateArrowTransformation successfully executes plugin lifecycle and collects transform configuration
