A good-enough copy means that both are indistinguishable—there’s no “original” and “copy”, just two forks from the same history.
Hm. What’s your opinion on imperfect copies, like you can look at your blood with a microscope and tell for sure if you are the original, naturally grown person or a person assembled from nutrient slurry in couple minutes? But you are incapable of telling introspectively.
Depends on the impact of the differences in cognition and experience. I’d imagine that many small differences could be physically detectable, but not qualia-impacting. Both copies experience continuity from before the fork. Maybe one (or both) have a slight perceptible change, like getting a bad night of sleep in the single-thread case. But it’s not enough to break the experience of continuity for either one.
