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. render mounts React components into the DOM and returns container, rerender, and unmount utilities
  2. screen provides pre-bound queries (getByTestId, getByRole, getByText) to document.body for finding rendered elements
  3. fireEvent dispatches DOM events wrapped in act to trigger component event listeners and state updates
  4. rerender updates rendered component props and reflects updated DOM output
  5. renderHook mounts custom React hooks and exposes reactive result.current alongside rerender and unmount helpers
  6. act wraps synchronous state modifications to flush pending React effects and lifecycle updates
  7. cleanup unmounts active component trees and clears DOM elements from document.body
