A data diode cannot fetch: on-prem inference, guarded retrieval, and the question that leaks
Teams that keep inference on-prem eventually want the model to read the outside world. The instinct is to buy a data diode. A diode solves half the problem and hides the other half: the question the model asks is itself the leak. This is the architecture that survives that fact, and an honest account of how much of it we have built.
