Lines of scrollback kept for [`Program.output`](/en/ts/latest/reference/program-program-output/), for `"session"`, up to tmux's 2147483647. Defaults to 100000; older lines are dropped, and [`ProgramResult.lostStart`](/en/ts/latest/reference/types-programresult-loststart/) says so. It bounds the output too: at most this many rows plus the screen's, each [`width`](/en/ts/latest/reference/types-spawnoptions-width/) columns, the newest kept.
