Scrollback accumulates
Tests whether lines scrolled off the top of the visible screen are preserved in the scrollback buffer. This is fundamental terminal behavior — without scrollback accumulation, users cannot scroll up to see previous output. Virtually all modern terminals maintain a scrollback buffer, though the maximum size varies.
