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

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. 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
  2. Piping the stream controller into a Writable destination upon onShellReady emits the rendered HTML string synchronously
  3. renderToString with a suspended component renders fallback HTML with diagnostic template markers instead of throwing or awaiting the promise
  4. react-dom/server in Node retains deprecated renderToNodeStream but omits renderToReadableStream
  5. react-dom retains legacy render and hydrate exports whereas modern createRoot and hydrateRoot reside in react-dom/client
