Well, I'm thinking that for the predicate editor in Xcode I need
something like "folder == SELF AND disabled = TRUE" with "item" as
destination, but that doesn't work. Woking from the "folder" end of
the relationship doesn't work either, at least for me and my tries
with the predicate syntax.
Am I overlooking something here?

"Fetch requests set on an NSFetchedProperty have 2 special variable
bindings you can use:$FETCH_SOURCE and $FETCHED_PROPERTY. The source
refers to the specific managed object that has this property; the
property refers to the NSFetchedProperty object itself (which may
have a user info associated with it that you want to use)."
