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 7 or 8 compatibility range
- Plugin factory returns an object named transform-block-scoped-functions with BlockStatement, SwitchStatement, and Loop visitor methods
- BlockStatement visitor transforms function declarations in strict-mode block scopes into let variable declarations with blockHoist 2
- BlockStatement visitor transforms function declarations in non-strict block scopes into var variable declarations
- BlockStatement visitor transforms async or generator function declarations in non-strict block scopes into let variable declarations
- BlockStatement visitor preserves non-function statements and ignores direct function body blocks or export declarations
- SwitchStatement visitor hoists nested function declarations from case consequents into an enclosing block statement
- Loop visitor traverses child blocks within loop structures
- Module helpers transform block-scoped function statements using the plugin and Babel core integration
