WHY IT NEEDS A POLICY

Why assistant_axis_session_end needs a policy

This tool terminates an active monitoring session and retrieves final metrics. Ending a session is a state-modifying action (Write) that closes/finalizes a session record. It is not destructive in the sense of permanently deleting data, and it retrieves a summary as a side effect. The blast radius is medium since terminating a session prematurely or unintentionally could disrupt ongoing monitoring workflows.
