DDD is the input. > Nope. YOU don't understand the meaning of the terms, perhaps because you don't understand what REALITY is. The "Behavior of the Input" comes from the input alone, and doesn't depend on the emulator doing anything. The emulation only REVEALS the behavior to the decider, not create it.
