I think this largely makes sense, and the idea is that we'll primarily test calculateScanPackagesUpdatedLoop, right?

We'd need a better name than nextLongScan, what is a "long scan"?

[isoos]

renamed to nextLongOverlap + added some description

Yes, I've added some tests.

I think we should also test the loop's logic, e.g. to execute the correct query for scanning and also to execute the task updates. But it is not yet clear to me how that should look like, and until that is figured out, we can start with the internals of the loops.
