You can visit Schengen following the expiry of a residence permit. The Schengen clock does not tick when you have a residence permit. It starts ticking when the permit expires (and at that point your 90 days will begin).
I wonder whether days before a residence permit are ever added to those after to count towards 90 total?
it's theoretical because a residence permit duration is normally 6 months or more. Haven't seen one for less than that, but if a residence permit was less than 6 months, then indeed visiting time would count. For sure.
