Thank you very much, @NagyDonat, for the review and useful comments - especially the code pointers, which I used in 7c6ffa87d87fed8097558a9b79e9fb321903239b. I believe that I have addressed all comments, and the code is ready for the next review.

Beyond resolving the comments, I added only one commit (d472fc44e684c120c3c30e4c67289507a9ada165), which, in my opinion, makes the tests more relevant to the scenario being tested.
