Word for the removal of a marked property [closed]

The use-case I'm working with is pretty simple. A record can be marked as deleted or removed by a method I named mark_deleted. However I can't find a good word for the reverse, the closest I've come is simply unmark but I feel like there should be a better option.

Solution 1:

Go for a single method that will remove the mark when is exists and add/set the mark when it doesn't and call it "toggle_deleted"

The verb "to toggle" is used in computing to switch or alternate between two settings, conditions, functions, etc. by means of a toggle. ¹

Solution 2:

If something is deleted, and you undelete it, what you are doing is restoring it.

Therefore, to me, the clearest opposite to mark_deleted is mark_restored.

Of course, you could also use synonyms like recovered—or even undeleted itself, if you don't mind its non-positive sense.

This also presumes that if something is neither deleted nor restored, it has no mark_ terminology associated with it.
