The driver-supplied hooks for the backend-specific session concerns (hosted live-view URL, native AI-control delegation, and backend release/teardown).
The Chrome DevTools Protocol connect endpoint the shared adapter attaches to. Either a raw CDP
websocket / http(s)://… DevTools endpoint or a Playwright browser-server ws(s)://… URL; the
shared provider attaches via CDP (ConnectType: 'cdp').
The result of a driver's BaseCdpRemoteBrowserProvider.AcquireSession hook: the CDP endpoint to attach to, plus the ICdpSessionBackend hooks for the backend-specific session concerns. This is the complete, consistent shape the 5 driver agents implement.
