LLM As Design Node

An LLM can participate in CPUX as a Design Node.

It should not become an invisible authority outside the Field.

It should absorb a Signal, reason within that bounded context, and emit a Signal that O_reflector can validate.

Input Signal

Example:

{
  "intention": {
    "id": "I_explain_movement_state"
  },
  "pulses": [
    {
      "phrase": "current light",
      "tv": "Y",
      "response": ["red"]
    },
    {
      "phrase": "current position",
      "tv": "Y",
      "response": ["4"]
    },
    {
      "phrase": "movement allowed",
      "tv": "N",
      "response": ["false"]
    }
  ]
}

The LLM is not asked to infer from an unbounded conversation.

It receives a represented situation.

DN Prompt Boundary

A CPUX-facing LLM DN can be prompted with the Signal contract:

You are a Design Node in CPUX.
Absorb the input Signal.
Emit only the expected result Signal.
Do not invent Pulse phrases.
Do not alter the input Signal.

The output expectation may be:

{
  "intentionId": "I_reflect_movement_explanation",
  "requiredPulses": [
    "movement explanation",
    "next human action suggested"
  ]
}

Expected Output Signal

{
  "intention": {
    "id": "I_reflect_movement_explanation"
  },
  "pulses": [
    {
      "phrase": "movement explanation",
      "tv": "Y",
      "response": ["Movement stopped because the current light is red."]
    },
    {
      "phrase": "next human action suggested",
      "tv": "Y",
      "response": ["Wait until the light becomes green."]
    }
  ]
}

O_reflector validates that this emitted Signal matches the designated output before reflecting it to the Field or UI.

Why This Matters

The LLM is powerful, but CPUX keeps it situated.

The model participates through:

• a bounded input Signal
• a declared Intention
• known Pulse phrases
• a designated output expectation
• O_reflector validation
• Field-visible reflection

This gives a safer and more inspectable role than allowing the LLM to mutate app state directly.

Developer Rule

Treat the LLM as a DN.

Do not let it bypass Signal contracts, O_reflector validation, or Field stabilisation.
