What is the Commonwealth storyline, and how does it differ in the comic versus the TV series?

The Commonwealth is a large, well-organized community with a pre-pandemic societal structure. In the comic, it's a major arc focusing on political intrigue, class disparity, and the challenges of rebuilding civilization. The show adapted this storyline, but significantly compressed it and altered key plot points, particularly regarding Pamela Milton's character and the ultimate fate of the Commonwealth. The comic's version is far more complex and politically charged.
