Which readings two windows disagree about, taken apart by the
direction they disagree in.
The two are worth seeing separately because they do not cost the
same. A separation leaves a visible edit in the apparatus that a
reader can challenge; a merge erases a reading and says nothing, and
the edition has no way to show what it lost. So the merges are the
list to read first, and an edge that only separates is the safer kind
of change however many readings it touches.
This is what to ask before applying a calculated window, rather than
reading admittedAsStated off the departures, which sees separations
only. An edge both windows agree about throughout needs no
re-collation at all, and its tolerance may simply be stated.
