WHY IT NEEDS A POLICY

Why docs_update_access needs a policy

This tool modifies access control permissions on documents. While it is a reversible write operation (roles can be changed again), misuse by an AI agent could grant unauthorized access or escalate privileges, making the blast radius high. It does not delete data, so Destructive does not apply.
