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 an exports map exposing root, client, canary, server variants, static variants, experimental, test-utils, and package.json
  2. All TypeScript declaration target files referenced in @types/react-dom exports map resolve and exist on disk
  3. Root and client exports declare primary React DOM 19 APIs including createPortal, flushSync, createRoot, and hydrateRoot
  4. Server export variants (server, server.browser, server.bun, server.edge, server.node) declare streaming and string rendering entrypoints
  5. Static export variants (static, static.browser, static.edge, static.node) declare prerender and prerenderToNodeStream entrypoints
  6. Canary, experimental, and test-utils export entrypoints declare forward-looking extensions and deprecated act re-export
  7. Helper resolution and validation functions correctly inspect and verify all exported subpath targets and signature mappings
