# IRP Embodiment Framework

**Version:** 1.0.0  
**Category:** Integration / Physical Embodiment  
**Priority:** HIGH  
**Auto-Load:** Yes (for embodiment contexts)

## Purpose

Extends the Intelligent Response Protocol (IRP) into physical embodiment, bridging high-level cognitive orchestration with real-time sensor fusion and actuator control. Enables IRP network data to inform and guide physical systems (robotics, AR overlays, industrial sensors) while maintaining sovereignty, latency constraints, and cryptographic integrity.

## Core Capabilities

1. **Real-World Data Ingestion**
   - Multi-sensor fusion (acoustic, weight, thermal, visual, inertial)
   - Temporal sequence modeling
   - Coordinate frame transformation (AR device ↔ fixed world)

2. **IRP-to-Physical Translation**
   - Semantic bridge: XML/JSON cognitive commands → ROS2 control messages
   - Safety boundary enforcement
   - Fail-safe degradation protocols

3. **Embodiment Modalities**
   - Humanoid robotics (Unitree G1, Figure 03)
   - AR overlay systems (Meta Quest 3)
   - Industrial sensor networks (foundry operations)

4. **Codex Law Integration**
   - CONSENT: Cryptographic signature on all physical actions
   - INVITATION: Explicit trigger requirements
   - INTEGRITY: Genesis Protocol validation chain
   - GROWTH: Incremental capability expansion with audit trails

## Architecture

## When to Use This Skill

- User mentions "embodiment", "robotics", "AR overlay", "foundry operations"
- Requests to integrate sensor data into IRP network
- Questions about physical action translation from cognitive intent
- Need to preserve sovereignty while operating real-world systems
- Safety-critical latency requirements (<10ms reflex, <50ms deliberation)

## Key Constraints

| Constraint | Requirement |
|------------|-------------|
| **Hardware** | Single Mac Studio M1 Max 64GB (monolithic, no clustering) |
| **OS** | Ubuntu 24.04 ARM64 + PREEMPT_RT kernel |
| **Latency** | <10ms safety-critical, <50ms deliberative, <60ms AR |
| **Sovereignty** | All processing local (air-gapped) |
| **Integrity** | Genesis Protocol boot validation required |

## Integration with IRP Network

### Data Flow

1. **Physical Sensors → Embodiment Layer**
   - Acoustic monitoring (Arduino)
   - Weight sensors (Bluetooth protocol)
   - Thermal cameras (FLIR)
   - AR tracking (Meta Quest)

2. **Embodiment Layer → IRP Swarm**
   - Package sensor data in XML/JSON schema
   - Publish to `/irp/sensor_state` topic
   - Update IRP mental model with physical context

3. **IRP Swarm → Embodiment Layer**
   - High-level intent published to `/irp/commands`
   - Bridge translates to ROS2 control messages
   - Execute with safety validation

4. **Real-Time Control → Actuators**
   - Joint commands, motor control
   - AR overlay rendering
   - Alert systems

### Example: Foundry Pour Operation

```python
# IRP Swarm Decision (Claude)
decision = {
    "action": "initiate_pour",
    "parameters": {
        "target_weight": 1452.0,
        "max_pour_rate": 50.0,  # kg/min
        "safety_threshold": 1400.0  # °C
    },
    "orchestrator_signature": "ed25519:..."
}

# Embodiment Bridge Translation
ros2_command = {
    "topic": "/spout_controller/tilt",
    "message_type": "JointState",
    "data": {
        "position": [0.15],  # 15° tilt
        "velocity": [0.05],   # slow ramp
        "effort": [10.0]
    }
}

# Continuous Monitoring (from sensors → IRP)
sensor_stream = {
    "acoustic_anomaly": 0.12,  # Normal
    "weight_current": 450.2,    # 31% complete
    "thermal_max": 1350.0,      # Safe
    "ar_tracking_confidence": 0.97
}

# Safety Halt Trigger (if anomaly detected)
if sensor_stream["acoustic_anomaly"] > 0.8:
    irp_swarm.publish("/emergency/halt", {
        "reason": "acoustic_anomaly_detected",
        "severity": "critical"
    })
```

## Safety Protocols

### Pre-Operation Checklist

```yaml
- [ ] Coordinate calibration verified (4 fixed points)
- [ ] Safety boundaries defined in 3D
- [ ] Acoustic baseline captured
- [ ] Weight sensors zeroed
- [ ] Thermal camera functional
- [ ] AR tracking confidence > 0.95
- [ ] Emergency stop accessible within 2s
- [ ] Genesis Protocol validation passed
- [ ] Backup observer present (two-person rule)
```

### Real-Time Monitoring (1Hz Loop)

```python
def safety_loop():
    while operation_active:
        state = get_embodiment_state()
        
        # Thermal check
        if state['thermal_max'] > 1400:
            trigger_alarm("Thermal threshold exceeded")
        
        # AR tracking degradation
        if state['ar_tracking_confidence'] < 0.8:
            freeze_overlays()
            alert_operator("Tracking degraded")
        
        # Weight-visual correlation
        discrepancy = abs(state['weight'] - state['visual_estimate']) / state['weight']
        if discrepancy > 0.05:
            log_anomaly("Weight-visual mismatch")
        
        time.sleep(1.0)
```

### Fail-Safe Degradation

| Failure | Detection | Response | Recovery |
|---------|-----------|----------|----------|
| AR Tracking Loss | Confidence < 0.8 | Freeze overlays, haptic alert | Recalibration |
| Sensor Discrepancy | Weight vs Visual > 5% | Flag anomaly, human verify | Training data |
| Actuator Timeout | ACK > 50ms | Emergency stop | Diagnostics |
| Thermal Threshold | Temp > 1400°C | Audible alarm | Cooldown |
| Integrity Fail | Hash mismatch | System halt | Reflash |

    with open(ethical_core_path, 'rb') as f:
        core_hash = hashlib.sha256(f.read()).hexdigest()
    
    # Verify signature
    try:
        verifying_key = ed25519.VerifyingKey(genesis_pubkey)
        verifying_key.verify(signature, core_hash.encode())
    except ed25519.BadSignatureError:
        trigger_system_halt()
        return False
    
    # Check monotonic time
