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
- listAllHelpers returns an array of runtime helper names including typeof, classCallCheck, and wrapRegExp
- hasHelper checks if a helper is registered in @babel/helpers list
- getHelperAst retrieves the AST node statements and globals for a helper declaration
- getHelperMinVersion returns the minimum Babel runtime version for a helper
- getHelperDependencies returns dependent helper names required by a helper
- isHelperInternal indicates whether a helper is flagged for internal compiler use
- ensureHelper succeeds for known helpers and throws BABEL_HELPER_UNKNOWN ReferenceError for unknown helper names
- getHelperAst throws BABEL_HELPER_UNKNOWN ReferenceError when requesting an unknown helper name
