I think one has "recovered" when the past is no longer negatively affecting their present life, and is accepted as having been. It's when one realizes that life "is" all those things that happen along the journey's path... it "is."

When one has to stop and think "if" the recovery process is complete (or nearly so) then it truly is, imo.

To add to the idea... perhaps one is fully "recovered" when they don't feel the need to differentiate from when they needed recovery to the present... and no longer think about "being" recovered.
