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 declares type definitions entry point index.d.ts, version 19.2.4, and subpath exports for client, server, and static entrypoints
- index.d.ts declaration file declares core React DOM 19 APIs including createPortal, flushSync, useFormStatus, and useFormState
- index.d.ts declares resource preloading and preinitialization APIs including preload, prefetchDNS, preconnect, and preinit
- client.d.ts declaration file declares createRoot, hydrateRoot, and client root management interfaces
- server.d.ts declaration file declares streaming and static rendering functions including renderToPipeableStream and renderToReadableStream
- static.d.ts declaration file declares React 19 static prerendering functions including prerender and prerenderToNodeStream
- Helper inspection module loads and verifies all React DOM 19 type declaration files and exported signature structures
