Trust your results because you checked them.
Once an import’s done, it’s tempting to just assume it worked and move on. Don’t hope, check. The way to do that is the same tool you started with: run a Healthcheck again.
Comparing the before-and-after picture is genuinely satisfying, you can see the count of broken references actually drop, in front of you, rather than just trusting that the repair did what it was supposed to. If anything’s still showing up, you’ll know immediately, while it’s still fresh and easy to address, rather than discovering it three gigs later.
