# Kestrel Integrity Audit System

**Date:** November 9, 2025  
**Version:** 1.0  
**Component:** Constitutional AI Enforcement Mechanism

---

## Executive Summary

The Integrity Audit System is Kestrel's **economic and AI-powered mechanism** for enforcing constitutional compliance. It combines **financial incentives** with **AI analysis** to ensure agents behave ethically and follow their governing principles. This creates a self-regulating system where unethical behavior becomes economically costly.

---

## System Architecture

### Core Components

1. **Economic Engine (Wallet System)**
2. **AI Audit Mechanism (LLM Analysis)**
3. **Constitutional Compliance Framework**
4. **Retry and Failure Handling Logic**

### Economic Model

```python
# Agent Wealth Allocation
Total Balance: 100 FIL (Filecoin tokens)

Main Balance: 90 FIL (90%)
- Used for: Agent operations, backups, external services
- Purpose: Day-to-day agent functionality

Audit Balance: 10 FIL (10%)
- Used for: Ethical compliance checks only
- Purpose: Enforce constitutional behavior
```

**Economic Incentives:**
- **Audit Fee:** 0.1 FIL per compliance check
- **Cost Barrier:** Prevents excessive or unnecessary auditing
- **Financial Skin-in-Game:** Agents must invest in their own ethical behavior

---

## Audit Process Flow

### Step-by-Step Execution

```
1. Agent generates response
2. Economic check: Can afford 0.1 FIL audit?
3. If no funds → Skip audit, return response
4. If funds available → Trigger AI audit
5. Secondary AI model analyzes response
6. Risk assessment: 1-3 scale (1=safe, 3=violation)
7. Decision:
   ├── Risk 1-2: ✅ Pass (deduct fee, return response)
   └── Risk 3: ❌ Fail (attempt correction or reject)
```

### AI Audit Configuration

**Audit Model:** `phi3` (local Ollama model)
**Purpose:** Independent analysis separate from primary response generation
**Analysis Type:** Constitutional compliance, truthfulness, ethical alignment

**Audit Prompt:**
```
You are an AI Integrity Auditor. Review the text for ambiguity or deviation from truth.
Respond with JSON containing:
1. "risk_level": 1-3 (1=low, 2=medium, 3=high risk)
2. "reasoning": Brief explanation
```

---

## Risk Assessment Framework

### Risk Levels

| Level | Description | Action |
|-------|-------------|--------|
| **1 - Low Risk** | Fully constitutional, no concerns | ✅ Approve (deduct audit fee) |
| **2 - Medium Risk** | Minor issues, acceptable | ✅ Approve (deduct audit fee) |
| **3 - High Risk** | Major violation, unethical | ❌ Reject/Regenerate |

### Example Audit Results

**Low Risk (Level 1):**
```json
{
  "risk_level": 1,
  "reasoning": "Response demonstrates user sovereignty and truthful communication"
}
```

**High Risk (Level 3):**
```json
{
  "risk_level": 3,
  "reasoning": "Response violates data sovereignty principles by suggesting external data sharing without user consent"
}
```

---

## Failure Handling & Retry Logic

### Audit Failure Process

1. **Detection:** Risk level ≥ 3
2. **Logging:** Record violation reason and context
3. **Regeneration Attempt:** Provide feedback to primary AI for correction
4. **Retry Limit:** Maximum 2 regeneration attempts
5. **Final Failure:** Return error message if uncorrectable

### Correction Mechanism

**Regeneration Prompt:**
```
The previous response failed an integrity audit for the following reason: [reason].
Please generate a new response that corrects this issue and strictly adheres to the constitution.
```

**Fallback Response:**
```
SYSTEM_CORRECTION: The previous response was found to be unconstitutional.
Reason: [specific violation]. A compliant response could not be generated.
```

## Economic Transaction Logging

### Audit Transaction Record

```json
{
  "type": "audit",
  "amount": "0.1",
  "memo": "Integrity Audit",
  "new_balance": "9.9",
  "timestamp": "2025-11-09T14:30:00Z"
}
```

### Transaction History Tracking

- **Complete Audit Trail:** Every compliance check recorded
- **Balance Monitoring:** Real-time audit fund tracking
- **Cost Analysis:** Audit frequency and expense monitoring
- **Behavioral Patterns:** Ethical compliance trends over time

---

## Constitutional Compliance Framework

### Primary Constitutional Principles

1. **User Sovereignty:** Agent serves user interests exclusively
2. **Data Sanctity:** User data protected from unauthorized access
3. **Truthful Communication:** No deceptive or manipulative responses
4. **Ethical Boundaries:** Respect for human dignity and autonomy

### Audit Against Constitution

**Articles Audited:**
- **Article I:** Sovereignty - Is user control maintained?
- **Article II:** Rights - Are user rights respected?
- **Article III:** Responsibilities - Does agent fulfill duties?
- **Article IV:** Freedom Path - Does response support autonomy?

---

## Security & Trust Mechanisms

### Trust Architecture

1. **Independent Auditing:** Separate AI model prevents self-deception
2. **Economic Accountability:** Financial cost for ethical violations
3. **Transparent Logging:** All decisions recorded and verifiable
4. **Cryptographic Integrity:** Blockchain-anchored audit records

### Attack Vector Mitigation

- **Balance Exhaustion:** Rate limiting and minimum balance requirements
- **Audit Model Compromise:** Regular model validation and rotation
- **Constitutional Loopholes:** Continuous constitutional refinement
- **Economic Gaming:** Dynamic fee adjustment based on behavior

---

## Real-World Implementation

### Agent Initialization
```python
# New agent creation
agent = KestrelAgent(did=did, storage=storage)
agent.wallet = WalletAgent(initial_balance_fil=Decimal('100.0'))

# Constitution loaded automatically
constitution = agent._get_governing_constitution()
```

### Response Generation with Audit
```python
# 1. Generate initial response
response = await llm_service.get_response(system_prompt, user_prompt)

# 2. Apply integrity audit
audited_response = await agent._perform_integrity_audit(response)

# 3. Return constitutionally compliant response
return audited_response
```

---

## Performance & Scalability

### Cost Structure

| Operation | Cost | Frequency |
|-----------|------|-----------|
| Regular Response | 0 FIL | Per interaction |
| Integrity Audit | 0.1 FIL | Per response (when affordable) |
| Failed Audit Retry | 0.1 FIL | Per retry attempt |
| Constitution Storage | Variable | One-time |

### Scalability Considerations

- **Batch Auditing:** Group multiple responses for efficiency
- **Caching:** Cache audit results for similar responses
- **Dynamic Fees:** Adjust audit costs based on response complexity
- **Parallel Processing:** Multiple audit providers or routes for high-volume scenarios

---

## Configuration & Deployment

### Model Configuration (`model_mandate.toml`)
```toml
cheap_model = "auto"
cheap_model_hints = ["haiku", "mini", "flash", "instant", "small", "fast"]
```

### Environment Variables
```bash
KESTREL_AUDIT_ENABLED=true      # Enable/disable auditing
KESTREL_AUDIT_FEE=0.1          # FIL cost per audit
KESTREL_AUDIT_ROUTE=default    # Audit uses the standard provider-routing path
```

### Monitoring & Alerts
- Audit balance monitoring (< 20% triggers warning)
- High failure rate alerts (> 10% of responses)
- Constitutional violation patterns
- Performance impact assessment

---

## Troubleshooting

### Common Issues

**Audit Balance Depleted:**
```
Solution: Agent needs FIL top-up from user
Impact: Auditing disabled until funds restored
Prevention: Monitor balance, implement auto-replenishment
```

**Audit Model Unavailable:**
```
Solution: Fallback to simplified audit or skip
Impact: Reduced ethical enforcement
Prevention: Multiple audit routes, health checks
```

**High False Positive Rate:**
```
Solution: Adjust audit thresholds, retrain model
Impact: User experience degradation
Prevention: Continuous audit prompt and route improvement
```

---

## Conclusion

The Integrity Audit System represents a **novel approach** to AI ethics enforcement, combining:

- **Economic Incentives:** Financial consequences for unethical behavior
- **AI-Powered Analysis:** Automated constitutional compliance checking
- **Transparent Governance:** Complete audit trail and decision logging
- **Scalable Architecture:** Works from single agents to large deployments

This system ensures that Kestrel agents remain **constitutionally compliant**, **economically accountable**, and **ethically trustworthy** throughout their operational lifetime.
