const ROWS_PAST_CUT: usize = 8;Expand description
How many rows past a page’s own count a cut may step back over, so that it does not open on a result without its call.
A call and its results are adjacent rows in every transcript measured, so one step is the ordinary case; the room is a short run of them - parallel calls written as several result frames - and a run longer than this ends the step rather than growing the page without bound.
