Finite cardinalities belong to dark endsegments.
Finite cardinals can change by 1
Yes. The last endsegments have 3, 2, 1, 0 elements.

No. All elements of finite endsegments (and almost all of infinite endsegments) are dark.
The endsegments
only can have an empty intersection
if there are endsegments with 3, 2, 1, 0 elements.
The end.segments
can only have a non.empty intersection
if there is an element which is in each end.segment.
That is the case for every non-empty endsegment before all elements are lost.
Otherwise two endsegments with different elements must exist. That is impossible by inclusion monotony.
