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
- @types/react-dom package.json defines types field pointing to index.d.ts and version 19.2.4
- @types/react-dom package exports declare TypeScript definition subpaths for client, server, static, canary, and experimental modules
- index.d.ts declares core DOM functions and hook state types including createPortal, flushSync, useFormStatus, and useFormState
- client.d.ts declares client rendering root functions createRoot and hydrateRoot along with Root and HydrationOptions interfaces
- server.d.ts and static.d.ts declare server streaming and prerendering APIs including renderToPipeableStream, renderToReadableStream, and prerender
- Inspection helpers correctly verify type declaration files existence and symbol content integrity
