Think of the topic title as the question, and the body of your post to contain more details of the problem, and any relevant examples.
The idea is to enable others to search for questions that have already been asked. Similar to StackOverflow. As such, try to ask only 1 question per thread.
I'll modify the title now to make it more discoverable, but try keeping this in mind for the next question.
Edit: I can't simplify the thread title. There are too many questions in your post.
I'll close this and ask that you open a new thread with a single question so it can be found by searching later on.
CVEI are guidelines for how you might want to think about your pipeline, but it is by no means mandatory. You could do exactly as you described, or you could come up with your own, perhaps more suitable, approach.
As an example, you might extract to..
And during integration, you might move this to..
And then delete the temporary folder.
Or you can extract into the final directory in one go and see where that takes you.
Of course. Wherever CVEI isn't a perfect fit, simply adapt it. They are guidelines, not rules.
