Scratches and marks in AR chambers..... What is excessive and what is OK?

I hope, however, that one of our members who has experience in metallurgy or inspection can give us a read on the first two images. I have only a lttle experience in this area, but they suggest that the barrel steel itself has cracks and inclusions. That could be a safety issue.

I see no cracks...
I have seen fire cracking throughout the rifling and chambers of a lot of older barrels in the past but, theses are scratches and nicks in the chamber neck & throat.
