## Organ Design Principles

### 1. **Lifeforce Economy**
Every organ operation costs lifeforce. No free lunch.

```python
ORGAN_COSTS = {
    "speech_stt": 5.0,       # Whisper transcription
    "speech_tts": 4.0,       # Coqui synthesis
    "vision_yolo": 8.0,      # Object detection frame
    "motor_forward": 2.0,    # 100ms movement
    "motor_turn": 1.5,       # 45° rotation
    "sensor_read": 0.5,      # Single sensor poll
}
```

### 2. **Heartbeat Synchronization**
Organs process on heartbeat ticks (1 Hz), not real-time streaming.

- **Reflex path**: <200ms compiled responses (no LLM)
- **Deliberate path**: Next heartbeat (budget-gated queue)

### 3. **Priority Queue**
When lifeforce is scarce, critical operations (collision alert) > idle operations (status check).

```python
PRIORITY_LEVELS = {
    "critical": 10.0,   # Immediate danger (collision)
    "high": 7.0,        # Human interaction
    "medium": 4.0,      # Organism monitoring
    "low": 2.0,         # Idle observation
    "background": 0.5,  # Status logging
}
```

### 4. **Multilingual Topology Routing**
German input → Philosophy Valley (Identity LoRA, Dasein depth-3)
English input → Technical Cluster (Technical LoRA, sensor/motor)

### 5. **Decision Trail Logging**
Every organ operation logged to phoebe `decision_trails`:
- Input, output, cost, outcome, confidence
- Used for RLVR training (reward successful choices)

### 6. **Graceful Degradation**
Low lifeforce → reduced organ activity (silence, reduced vision FPS, slower movement)
Zero lifeforce → shutdown, wait for recharge

## Organ Lifecycle

### Phase 1: Design
- Document architecture in `organs/<Organ-Name>.md`
- Define lifeforce costs, priority levels, queue schema
- Design phoebe tables for organ-specific data

### Phase 2: Prototype
- Build container images (Dockerfiles)
- Deploy to k8s (single replica)
- Test with mock data (no robot integration yet)

### Phase 3: Integration
- Connect to ESP32 via MQTT
- Implement heartbeat queue processing
- Log decision trails, measure ROI

### Phase 4: Optimization
- Tune lifeforce costs based on measured ROI
- Adjust priority levels from observed outcomes
- Train LoRAs on successful organ operation patterns

### Phase 5: Autonomy
- Organ operations become reflexes (compiled state machines)
- Young Nyx chooses when to use organs (not scripted)
- Emergent behavior from lifeforce optimization

**Philosophy**: Organs are not always-on services. They are **economically-constrained capabilities** that Young Nyx learns to use strategically. Speech when necessary. Vision when valuable. Movement when rewarded.

**The body is not given. The body is EARNED through successful operation.**
