What

In a multi-agent team session, when a pending permission request is resolved by a message from the team lead, that incoming message is now checked by a forgery classifier before being accepted as the real decision. Messages tagged as "forged" are discarded rather than acted on.

Why

This prevents a spoofed or malicious message from impersonating the team lead to approve or deny a permission request in a team session.
