+    # Simulate double signing
+    event = mock_slashing.detect_double_sign(

+
+## 🔗 **Integration Testing**
+
+### **Cross-Phase Workflows**
+1. **End-to-End Job Execution**
+   - Client creates job → Agent matches → Escrow funded → Work completed → Payment released
+
+2. **Consensus with Network**
+   - Validators discover peers → Form consensus → Propagate blocks → Handle partitions
+
+3. **Economics with Agents**
+   - Agents earn rewards → Stake tokens → Reputation affects earnings → Economic incentives
+
+4. **Contracts with All Layers**
+   - Escrow created → Network validates → Economics processes → Agents participate
+
+### **Test Scenarios**
+```python
+@pytest.mark.asyncio
+async def test_end_to_end_job_execution_workflow(self):
+    """Test complete job execution workflow across all phases"""
+    # 1. Client creates escrow contract
+    success, _, contract_id = mock_escrow.create_contract(...)
+    
+    # 2. Find suitable agent
+    agents = mock_agents.find_agents("text_generation")
+    
+    # 3. Network communication
+    success, _, _ = mock_protocol.send_message(...)
+    
+    # 4. Consensus validation
+    valid, _ = mock_consensus.validate_transaction(...)
+    
+    # 5. Complete workflow
+    assert success is True
