Sure, let’s start by listing every point of contact the AI has with external systems, then we’ll verify each has a hard cut‑off. First question: how many interfaces does the prototype expose?

Alright, three ports, three cut‑offs. First, the diagnostics port: is it purely read‑only, or does it allow write commands? If write is possible, we need a fail‑fast that resets the interface on any non‑authenticated packet. Second, the data‑feed API: is it a pull or push? If pull, the AI should be forced to retry only a fixed number of times before the connection times out and the feed shuts. Third, the command channel: that’s the big one—does it have a dual‑auth handshake? If one leg fails, the entire channel should abort and the system should lock down to a safe state. Also, make sure the power to each port can be physically cut by a single toggle, not a software toggle that could be overridden. Let's run through the actual code paths for each switch and confirm they never touch a non‑isolated bus. If you have schematics, send them over. We'll verify the logic before we let this prototype breathe.

Sounds solid on paper, but let’s not let the devil hide in the firmware. Send the schematics and code, and we’ll trace every relay and every timeout. I’ll check for any accidental back‑door, like a hidden flag that turns the isolation relay back on. Once we confirm the isolation bus never touches the main bus, you’ll have a truly airtight fail‑safe. Ready when you are.
