Ignore test run failures for now. They are currently unrelated.

Sorry that it took me so long to respond. I was busy and also travelling a bit. And this was not something I could just review on my phone 😅

Basically everything I criticized in the review is readability related. This is not completely on you, this block of code with multi-stage checks is already not very readable the way it is now. But it took me quite a while to understand what's going on with your additional 'flags' mixed into the other steps. Making the additional check self-contained should increase readability quite a bit.

Good morning!!! Thank you for your precious suggestions.
In the last commit I followed your ideas trying to keep check_4 self-contained. I only left two conversations unresolved to see what you think and suggested a personal improvement to one of them. Let me know your thoughts about 😄

That looks much more readable already. I made one more suggestion regarding the duplicate integrity error for a single lap. But after that, I think this is good to merge.

Edit: line length needs to be fixed though

Good morning! I've resolved the conversations and fixed the line length of the code i wrote. Please note for the future that other lines of core.py needs to be fixed for line length, too.

For any other issues please let me know. Thank you!

Everything looks good now, thank you!

Please note for the future that other lines of core.py needs to be fixed for line length, too.

Yes, that's why the line length rule is currently only enforced on changes, so that the overall code base slowly moves towards proper line length. That's less intrusive than doing one huge commit that changes hundreds or thousands of lines throughout all files.
