REA integrates native Chrome DevTools Protocol inspection and precise V8 coverage through two composable tools. Supply an existing loopback CDP endpoint and a page target from list_browser_targets. With omitted origins, REA selects the page's current HTTP(S) origin. The browser and page remain externally owned.
