> When no one owns copyrights - everyone does. Both you and you custom have full rights to copy and distribute those parts of software as do everyone else, you just don't own exclusive rights (copyrights) to control whether and how anyone else can also copy those parts of software. Do you own copyright for number "10", does it mean you can't use it in your software.
Yes. It can be an issue depending of the wording of your agreement with the customer. For example, if 'you' agreed to develop a piece of software 'exclusively' for the customer, and then use AI to create substantial parts of the software, then neither it was 'you' who developed that, nor was it 'exclusively' for the customer as you can't grant exclusivity.

On the other hand, if ‘you’ had taken no action at all, then there would be no software at all. The actions by ‘you’ are necessary for the software to exist, so the argument must be about whether those actions count as development or not. Is the definition of development written down anywhere?

I think it is, but I'm not a German lawyer, so I'll just link what I did in another comment - it revolves around the question who is the Geistiger Schöpfer (lit. spiritual creator) https://sta.dnb.de/doc/RDA-E-W135

Definition? Yes, but it's required over a hundred years of jurisprudence to apply it to different scenarios, in the US at least. It's amusing that you think the definition would clear things up.
