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