browser_timetravel
Reconstruct a complete browser session at any past moment to debug failures. View screen, console, network, and storage as they were exactly at that time.
Instructions
TIME MACHINE — THE HEADLINE VERB. Reconstruct EVERYTHING as it was at a single moment: the screen (path to the nearest visual frame), local/session storage, cookies, page state, the console tail, the network activity in the surrounding window, the anchoring action, and the windowed event timeline. Anchor by absolute time (at), by an event sequence number (seq), or — most useful — beforeLastError to land just before the last failure. Operates on a loaded past session if one is loaded, else the live session. This is what a snapshot tool can never do: go back in time and see the whole picture.
