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 declaring Babel version compatibility
- Plugin factory returns an object named transform-duplicate-named-capturing-groups-regex with manipulateOptions, pre, and visitor.RegExpLiteral
- Plugin factory throws an Error when runtime option is non-boolean
- Plugin pre() sets duplicateNamedCaptureGroups feature flag and runtime options on Babel file context
- RegExpLiteral visitor compiles duplicate named capturing groups to numbered groups and wraps with wrapRegExp helper when runtime is true
- RegExpLiteral visitor compiles duplicate named capturing groups without wrapRegExp when runtime is false
- RegExpLiteral visitor skips wrapRegExp helper wrapping when RegExp is used in a test method expression
- RegExpLiteral visitor leaves regular expressions without duplicate named groups unchanged
