What session_speichern does on Lokyy

WHY IT NEEDS A POLICY

Why session_speichern needs a policy

This tool creates a new record (session source) in the knowledge base by saving chat insights to RAW/sessions/. It is a reversible write operation (data creation/storage), not destructive, financial, or executable. Severity is medium because an AI agent could write unintended or sensitive data into the knowledge base, but the blast radius is limited to the session store.

From the tool's definition 'Hält die Kernerkenntnisse eines Chats als Quelle in RAW/sessions/ fest' — stores/persists core insights of a chat session as a source entry
