Following. Statutory ground.
The grid switches only on signed authority.
Critical infrastructure is where AI-assisted operation meets statutory obligation. Australia's SOCI framework already requires affected operators to identify, manage, and mitigate material risks to the assets that keep power, water, and industry running. As optimisation and control move toward AI, the question sharpens: when the control system proposes a switching operation, a dosing change, or a load transfer, what stands between proposal and consequence?
PEC-1 stands exactly there. Breaker and switch commands gate against signed switching programs. Dose and flow policy holds at the pumps and valves themselves, so compromised upstream control software cannot directly issue a protected command outside signed operating policy. Maintenance lockouts become physical while someone is up the tower. The AI proposes; the interlock decides; the record is tamper-evident.
What PEC-1 enforces here
Switching custody. Grid operations execute only against signed programs, whatever the control system believes.
Process ceilings. Dosing, flow, pressure, and transfer limits enforced at the actuator, independent of the software stack.
Statutory evidence. Tamper-evident audit records of every protected enforcement decision, supporting risk-management, assurance, and incident-review obligations.
