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

Contract
- Plugin default export is a function factory asserting Babel version 7 compatibility
- Plugin factory returns a plugin object named transform-react-jsx-source with JSXOpeningElement visitor
- Injects __source attribute with fileName, lineNumber, and columnNumber into JSXOpeningElement
- Injects fileName variable declaration at program scope matching provided filename
- Calculates 1-based columnNumber and lineNumber from AST node loc start position
- Preserves existing __source attribute on JSXOpeningElement without duplicate injection
- Handles nested JSX elements injecting independent source locations for each element
- Handles JSX elements without location metadata without error
- Helper functions createReactJsxSourcePlugin and transformReactJsxSource correctly transform JSX source code
