Audit agent tri-mode, porte blindée + caméra + vigile
Production agent governance pattern: a lone agent is a risk; an agent with 3 simultaneous auditors (Mode 1 blocking, Mode 2 traceability, Mode 3 learning) is a system that compounds. Articulated by Willy (Gouvernance IA): most people use zero modes, some 1, almost nobody all 3. Covers the surveillance angle agent-governance-chassis (mandate) does not.
