'Unstable' seems good, but what if 'unstable' was used in place of 'troubled',
and this case was called an 'orphan'? I realize it's still connected in the
DAG, so not truly an orphan, but with obsolete csets generally being hidden, it
might better convey the concept.
This might work better if the command to resolve all of these cases is
'stabilize'. (FWIW, the command 'evolve' conjures an image of the thing that
would place obsolete markers and cause a cset to evolve into another, not
necessarily the command to fix these problems. IDK if the plan was to have an
all in one command or not.)

'Mutant'? Given that it applies to a cset that is attempting to replace
something that is immutable, I think that also gives more clarity to the
particular scenario (i.e. there's a mutant of something that is immutable).
