WHY IT NEEDS A POLICY

Why remove_from_cart needs a policy

Removing an item from a shopping cart is a reversible write operation — the item can be re-added. It modifies state (the cart) but does not commit any financial transaction, delete data permanently, or execute code. Severity is medium because misuse could disrupt a user's shopping session, but the action is easily undone.
