====== Tombstone ======

**Tombstones** represent any object that previously used to exist but has since been deleted, and are one of the 5 types of pushable [[:object]]. It's not necessary to keep the tombstone object around forever after deleting something, but as it acts as a notification to other [[:instances]] to delete an object from their own databases, it should at the very least be [[:push|pushed]] to the same instances the original object was pushed to (and ideally to every instance that ever fetched the original object if possible).
