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 version compatibility
- Plugin factory returns an object named transform-class-properties with manipulateOptions, pre, and visitor
- manipulateOptions adds classProperties and classPrivateProperties to parser plugins array
- Plugin accepts options including loose mode configuration
- Visitor provides Class and ExportDefaultDeclaration visitor methods for AST transformation
- Module helpers instantiate the plugin, configure parser options, and extract visitors
