WHY IT NEEDS A POLICY

Why unpublish-story needs a policy

Unpublishing a story reverses its public visibility but does not delete it — the content remains in the CMS and can be republished. This is a reversible state change, making it a Write operation. However, severity is high because taking live content offline can have significant impact on production websites or applications relying on that content being published.
