WHY IT NEEDS A POLICY

Why start_work_session needs a policy

This tool creates a new work session record (a session ID), which is a reversible write operation. It does not execute code, delete data, or involve financial transactions. The blast radius is low since it only initializes a session state that can be ended via end_work_session.

From the tool's definition 'Start a work session from a tool. Returns session ID for use with end_work_session.'
