Sliding door does not completely disappear into the wall

Now your answer sounds completely different. Because in your first post you didn't even accuse the team of writing this simple sentence that your daughter could also write. So what is it now? But yes, we have managed in Germany that for a simple door that should be flush with the wall, a requirements specification with two pages is needed.

No. But a simple statement from the OP to the craftsman along the lines of "please install a flush door" is not too much to ask. It is comparable to an interior door. Rebated or non-rebated. What is the standard? Both are normal.

What always surprises me a bit are these conversations in which the answers often assume facts that actually cannot be found anywhere. How exactly the agreement between the craftsman and the client took place can be imagined based on the initial post but cannot be known. Nevertheless, people speak as if it is very clear who is "at fault." What I want to say: There are posts for one side as well as the other, where my impression is that positions are taken without being able to definitely recognize where a mistake might have been made. As if it is not about the matter, but about arguing. I do not consider arguing to be a bad thing, but it should make sense. At least that's what I think.

It doesn’t surprise me. The OP is asked at least 6 questions, with or without question marks. If nothing comes of it, one could assume that the OP “takes the blame” – regardless of whether someone is looking for a culprit or not. A lot is being asked here about how it came to be, people are participating in problem-solving – except the OP.

one could assume that

that's exactly what I mean. you don't know, but it is assumed as if the facts were clear.

Especially when the original poster does not want or cannot make a clear statement, from my perspective there is absolutely no reason to take a stand.

I just wanted to make it clear that "dispute without cause" surprises me (and yes: honestly it often annoys me quite a bit. But that's my problem, which I can cope with)

Thank you for the numerous responses, which indeed differ quite considerably in opinion.

Yes, we are laypeople, not craftsmen ourselves, it is our first house, and honestly, I have never seen a sliding door where a part of it protruded from the wall. (although, of course, I hadn’t really paid attention to such things before)
In our old rental apartment, we also had a sliding door, where the door panel disappeared completely into the wall and there was also this little hook to pull it out.
But the house was from 1950 and I have no idea whether such doors are still sold/installed today. Apparently, in this case, that is already the case, and maybe it could also be retrofitted.

In that respect, I would have of course wished for somewhat better advice – the carpenter could have asked: do you want it like this or do you want it like that?

Currently, it does bother us a bit, it simply makes the doorway relatively narrow, and actually, we don’t plan to close the sliding door often, except when someone is cooking something very greasy or smelly or the loud extractor fan is on while people want to talk in the living/dining area. But I could imagine that will be at most once a month.

I will contact the carpenter again to see if it can still be retrofitted, if necessary at our expense, if it really bothers us a lot, which will surely become clear in the next 2-3 months.

Many thanks for all all your opinions
