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
- renderToPipeableStream returns a synchronous { pipe, abort } controller object that is neither a Readable stream nor a Promise, where pipe(dest) returns the passed writable destination
- Piping the stream controller into a Writable destination upon onShellReady emits the rendered HTML string synchronously
- renderToString with a suspended component renders fallback HTML with diagnostic template markers instead of throwing or awaiting the promise
- react-dom/server in Node retains deprecated renderToNodeStream but omits renderToReadableStream
- react-dom retains legacy render and hydrate exports whereas modern createRoot and hydrateRoot reside in react-dom/client
