+
+# Find drop-in files
+rg "Conflicts=|After=" --type systemd /etc/systemd/system/aitbc-*.service.d/
+```
+
+## Common AITBC Tasks
+
+### Path Migration Analysis
+```bash
+# Find all data path references
+rg "/opt/aitbc/data" --type py /opt/aitbc/production/services/
+
+# Find all config path references
+rg "/opt/aitbc/config" --type py /opt/aitbc/
+
+# Find all log path references
+rg "/opt/aitbc/logs" --type py /opt/aitbc/production/services/
+
+# Generate replacement list
+rg "/opt/aitbc/(data|config|logs)" --only-matching --type py /opt/aitbc/ | sort -u
+```
+
+### Service Configuration Audit
+```bash
+# Find all service files
+rg "aitbc.*\.service" --type systemd /etc/systemd/system/
+
+# Check EnvironmentFile usage
+rg "EnvironmentFile=" --type systemd /etc/systemd/system/aitbc-*.service
+
+# Check ReadWritePaths
+rg "ReadWritePaths=" --type systemd /etc/systemd/system/aitbc-*.service
+
+# Find service dependencies
+rg "After=|Requires=|Wants=" --type systemd /etc/systemd/system/aitbc-*.service
+```
+
+### Code Quality Checks
+```bash
+# Find potential security issues
+rg "password|secret|token|api_key" --type py --type yaml /opt/aitbc/
+
+# Find hardcoded URLs and IPs
+rg "https?://[^\s]+|[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}" --type py /opt/aitbc/
+
+# Find exception handling
+rg "except.*:" --type py /opt/aitbc/ | head -10
+
+# Find TODO comments
+rg "TODO|FIXME|XXX" --type py /opt/aitbc/
+```
+
+## Advanced Patterns
+
+### Regex Mastery
+```bash
+# System path validation
+rg "/(var|etc|opt)/aitbc/(data|config|logs)" --type py /opt/aitbc/
+
+# Port number validation
+rg ":[0-9]{4,5}" --type py /opt/aitbc/
+
+# Environment variable usage
+rg "\${[A-Z_]+}" --type py --type yaml /opt/aitbc/
+
+# Import statement analysis
+rg "^import |^from .* import" --type py /opt/aitbc/
+
+# Function definition analysis
+rg "^def [a-zA-Z_][a-zA-Z0-9_]*\(" --type py /opt/aitbc/
+```
+
+### Complex Searches
+```bash
+# Find files with multiple patterns
+rg "pattern1" --files-with-matches --type py /opt/aitbc/ | xargs rg -l "pattern2"
+
+# Context-specific searching
+rg "class.*:" -A 10 --type py /opt/aitbc/
+
+# Inverse searching (files NOT containing pattern)
+rg "^" --files-with-matches --type py /opt/aitbc/ | xargs rg -L "pattern"
+
+# File content statistics
+rg "." --type py /opt/aitbc/ --count-matches | awk '{sum += $2} END {print "Total matches:", sum}'
+```
+
+## Troubleshooting and Debugging
+
+### Common Issues
+```bash
+# Check ripgrep version and features
+rg --version
+
+# Test pattern matching
+rg "test" --type py /opt/aitbc/ --debug
+
+# Check file type recognition
+rg --type-list
+
+# Verify gitignore integration
+rg "pattern" --debug /opt/aitbc/
+```
+
+### Performance Debugging
+```bash
+# Time the search
+time rg "pattern" --type py /opt/aitbc/
+
+# Check search statistics
+rg "pattern" --stats --type py /opt/aitbc/
+
+# Benchmark different approaches
+hyperfine 'rg "pattern" --type py /opt/aitbc/' 'grep -r "pattern" /opt/aitbc/ --include="*.py"'
+```
+
+## Best Practices
+
+### Search Optimization
+1. **Use specific file types**: `--type py` instead of generic searches
+2. **Leverage gitignore**: Ripgrep automatically respects gitignore rules
+3. **Use appropriate patterns**: Word boundaries for precise matches
+4. **Limit search scope**: Use specific directories when possible
+5. **Consider alternatives**: Use `rg --files-with-matches` for file lists
+
+### Pattern Design
+1. **Be specific**: Use exact patterns when possible
+2. **Use word boundaries**: `\bword\b` for whole words
+3. **Consider context**: Use lookarounds for context-aware matching
+4. **Test patterns**: Start broad, then refine
+5. **Document patterns**: Save complex patterns for reuse
+
+### Performance Tips
+1. **Use file type filters**: `--type py` is faster than `--glob "*.py"`
+2. **Limit search depth**: `--max-depth` for large directories
+3. **Exclude unnecessary files**: Use gitignore or explicit exclusions
+4. **Use appropriate output**: `--files-with-matches` for file lists
+5. **Consider memory usage**: `--max-filesize` for large files
+
+## Integration Examples

+
+## 🔧 **Troubleshooting**
+
+### **Common Issues**
+
+#### **Black Formatting Issues**
+```bash
+# Check formatting issues
+./venv/bin/black --check .
+
+# Auto-fix formatting
+./venv/bin/black .
+
+# Specific file
+./venv/bin/black --check path/to/file.py
+```
+
+#### **Import Sorting Issues**

+# Check import sorting
+./venv/bin/isort --check-only .
+
+# Auto-fix imports
+./venv/bin/isort .
+
+# Specific file
+./venv/bin/isort path/to/file.py
+```
+
+#### **Type Checking Issues**
+```bash
+# Check type errors

+- **Service Status**: Healthy and operational
+- **Code Quality**: Type-safe and validated
+- **Security**: Enterprise-grade
+- **Monitoring**: Full observability
+
+---
+
+## 🚀 **Pre-Flight Validation**
+
+### **🔍 System Health Check**
+```bash
+# 1. Verify service status
+systemctl status aitbc-agent-coordinator.service --no-pager
+
+# 2. Check service health endpoint
+curl -s http://localhost:9001/health | jq '.status'
+
+# 3. Verify port accessibility
+netstat -tlnp | grep :9001
+```
+
+**Expected Results**:

+  -H "Content-Type: application/json" \
+  -d '{"username": "admin", "password": "admin123"}' | jq -r '.access_token')
+
+# 2. Verify token received
+if [ "$TOKEN" != "null" ] && [ ${#TOKEN} -gt 20 ]; then 
+  echo "✅ Authentication working: ${TOKEN:0:20}..."
+else
+  echo "❌ Authentication failed"
+fi
+
+# 3. Test protected endpoint
+curl -s -H "Authorization: Bearer $TOKEN" \
+  http://localhost:9001/protected/admin | jq '.message'
+```
+
+**Expected Results**:

+# Type Checking CI/CD Workflow
+
+## 🎯 **Overview**
+Comprehensive type checking workflow that ensures type safety across the AITBC codebase through automated CI/CD pipelines, coverage reporting, and quality gates.
+
+---
+
+## 📋 **Workflow Steps**
+
+### **Step 1: Local Development Type Checking**
+```bash
+# Install dependencies
+./venv/bin/pip install mypy sqlalchemy sqlmodel fastapi
+
+# Check core domain models
+./venv/bin/mypy --ignore-missing-imports --show-error-codes apps/coordinator-api/src/app/domain/job.py
+./venv/bin/mypy --ignore-missing-imports --show-error-codes apps/coordinator-api/src/app/domain/miner.py
+./venv/bin/mypy --ignore-missing-imports --show-error-codes apps/coordinator-api/src/app/domain/agent_portfolio.py
+
+# Check entire domain directory
+./venv/bin/mypy --ignore-missing-imports apps/coordinator-api/src/app/domain/
+
+# Generate coverage report
+./scripts/type-checking/check-coverage.sh
+```
+
+### **Step 2: Pre-commit Type Checking**
+```bash
+# Pre-commit hooks run automatically on commit
+git add .
+git commit -m "Add type-safe code"
+
+# Manual pre-commit run
+./venv/bin/pre-commit run mypy-domain-core
+./venv/bin/pre-commit run type-check-coverage
+```
+
+### **Step 3: CI/CD Pipeline Type Checking**
+```yaml
+# GitHub Actions workflow triggers on:
+# - Push to main/develop branches
+# - Pull requests to main/develop branches
+
+# Pipeline steps:
+# 1. Checkout code
+# 2. Setup Python 3.13
+# 3. Cache dependencies
+# 4. Install MyPy and dependencies
+# 5. Run type checking on core models
+# 6. Run type checking on entire domain
+# 7. Generate reports
+# 8. Upload artifacts
+# 9. Calculate coverage
+# 10. Enforce quality gates
+```
+
+### **Step 4: Coverage Analysis**
+```bash
+# Calculate type checking coverage
+CORE_FILES=3
+PASSING=$(./venv/bin/mypy --ignore-missing-imports apps/coordinator-api/src/app/domain/job.py apps/coordinator-api/src/app/domain/miner.py apps/coordinator-api/src/app/domain/agent_portfolio.py 2>&1 | grep -c "Success:" || echo "0")
+COVERAGE=$((PASSING * 100 / CORE_FILES))
+
+echo "Core domain coverage: $COVERAGE%"
+
+# Quality gate: 80% minimum coverage
+if [ "$COVERAGE" -ge 80 ]; then
+  echo "✅ Type checking coverage: $COVERAGE% (meets threshold)"
+else
+  echo "❌ Type checking coverage: $COVERAGE% (below 80% threshold)"
+  exit 1
+fi

+          exit 1
+        fi
+```
+

+
+## 📊 **Coverage Reporting**
+
+### **Local Coverage Analysis**
+```bash
+# Run comprehensive coverage analysis
+./scripts/type-checking/check-coverage.sh
+
+# Generate detailed report
+./venv/bin/mypy --ignore-missing-imports --txt-report reports/type-check-detailed.txt apps/coordinator-api/src/app/domain/
+
+# Generate HTML report
+./venv/bin/mypy --ignore-missing-imports --html-report reports/type-check-html apps/coordinator-api/src/app/domain/
+```
+
+### **Coverage Metrics**
+```python
+# Coverage calculation components:
+# - Core domain models: 3 files (job.py, miner.py, agent_portfolio.py)
+# - Passing files: Files with no type errors
+# - Coverage percentage: (Passing / Total) * 100
+# - Quality gate: 80% minimum coverage
+
+# Example calculation:
+CORE_FILES = 3
+PASSING_FILES = 3
+COVERAGE = (3 / 3) * 100 = 100%
+```
+
+### **Report Structure**
+```

+```
+
+---
+
+## 🚀 **Integration Strategy**
+
+### **Development Workflow Integration**
+```bash
+# 1. Local development
+vim apps/coordinator-api/src/app/domain/new_model.py
+
+# 2. Type checking
+./venv/bin/mypy --ignore-missing-imports apps/coordinator-api/src/app/domain/new_model.py
+
+# 3. Pre-commit validation
+git add .
+git commit -m "Add new type-safe model"  # Pre-commit runs automatically
+
+# 4. Push triggers CI/CD
+git push origin feature-branch  # GitHub Actions runs
+```
+
+### **Quality Gates**
+```yaml
+# Quality gate thresholds:
+# - Core domain coverage: >= 80%
+# - No critical type errors in core models
+# - All new code must pass type checking
+# - Type errors in existing code must be documented
+
+# Gate enforcement:
+# - CI/CD pipeline fails on low coverage
+# - Pull requests blocked on type errors
+# - Deployment requires type safety validation
+```
+
+### **Monitoring and Alerting**
+```bash
+# Type checking metrics dashboard
+curl http://localhost:3000/d/type-checking-coverage
+
+# Alert on coverage drop
+if [ "$COVERAGE" -lt 80 ]; then
+  send_alert "Type checking coverage dropped to $COVERAGE%"
+fi
+
+# Weekly coverage trends
+./scripts/type-checking/generate-coverage-trends.sh
+```
+
+---
+
+## 🎯 **Type Checking Standards**
+
+### **Core Domain Requirements**
+```python
+# Core domain models must:
+# 1. Have 100% type coverage
+# 2. Use proper type hints for all fields
+# 3. Handle Optional types correctly
+# 4. Include proper return types
+# 5. Use generic types for collections
+
+# Example:
+from typing import Any, Dict, Optional
+from datetime import datetime
+from sqlmodel import SQLModel, Field
+
+class Job(SQLModel, table=True):
+    id: str = Field(primary_key=True)
+    name: str
+    payload: Dict[str, Any] = Field(default_factory=dict)
+    created_at: datetime = Field(default_factory=datetime.utcnow)
+    updated_at: Optional[datetime] = None
+```
+
+### **Service Layer Standards**
+```python
+# Service layer must:
+# 1. Type all method parameters
+# 2. Include return type annotations
+# 3. Handle exceptions properly
+# 4. Use dependency injection types
+# 5. Document complex types
+
+# Example:
+from typing import List, Optional
+from sqlmodel import Session
+
+class JobService:
+    def __init__(self, session: Session) -> None:
+        self.session = session
+    
+    def get_job(self, job_id: str) -> Optional[Job]:
+        """Get a job by ID."""
+        return self.session.get(Job, job_id)
+    
+    def create_job(self, job_data: JobCreate) -> Job:
+        """Create a new job."""
+        job = Job.model_validate(job_data)
+        self.session.add(job)
+        self.session.commit()
+        self.session.refresh(job)
+        return job
+```
+
+### **API Router Standards**
+```python
+# API routers must:
+# 1. Type all route parameters
+# 2. Use Pydantic models for request/response
+# 3. Include proper HTTP status types
+# 4. Handle error responses
+# 5. Document complex endpoints
+
+# Example:
+from fastapi import APIRouter, HTTPException, Depends
+from typing import List
+
+router = APIRouter(prefix="/jobs", tags=["jobs"])
+
+@router.get("/", response_model=List[JobRead])
+async def get_jobs(
+    skip: int = 0,
+    limit: int = 100,
+    session: Session = Depends(get_session)
+) -> List[JobRead]:
+    """Get all jobs with pagination."""
+    jobs = session.exec(select(Job).offset(skip).limit(limit)).all()
+    return jobs
+```
+
+---
+
+## 📈 **Progressive Type Safety Implementation**
+
+### **Phase 1: Core Domain (Complete)**
+```bash
+# ✅ Completed
+# - job.py: 100% type coverage
+# - miner.py: 100% type coverage  
+# - agent_portfolio.py: 100% type coverage
+
+# Status: All core models type-safe
+```
+
+### **Phase 2: Service Layer (In Progress)**
+```bash
+# 🔄 Current work
+# - JobService: Adding type hints
+# - MinerService: Adding type hints
+# - AgentService: Adding type hints
+
+# Commands:
+./venv/bin/mypy --ignore-missing-imports apps/coordinator-api/src/app/services/
+```
+
+### **Phase 3: API Routers (Planned)**
+```bash
+# ⏳ Planned work
+# - job_router.py: Add type hints
+# - miner_router.py: Add type hints
+# - agent_router.py: Add type hints
+
+# Commands:
+./venv/bin/mypy --ignore-missing-imports apps/coordinator-api/src/app/routers/
+```
+
+### **Phase 4: Strict Mode (Future)**
+```toml
+# pyproject.toml
+[tool.mypy]
+check_untyped_defs = true
+disallow_untyped_defs = true
+no_implicit_optional = true
+strict_equality = true
+```
+
+---
+
+## 🔧 **Troubleshooting**
+
+### **Common Type Errors**
+
+#### **Missing Import Error**
+```bash
+# Error: Name "uuid4" is not defined
+# Solution: Add missing import
+from uuid import uuid4
+```
+
+#### **SQLModel Field Type Error**
+```bash
+# Error: No overload variant of "Field" matches
+# Solution: Use proper type annotations
+payload: Dict[str, Any] = Field(default_factory=dict)
+```
+
+#### **Optional Type Error**
+```bash
+# Error: Incompatible types in assignment
+# Solution: Use Optional type annotation
+updated_at: Optional[datetime] = None
+```
+
+#### **Generic Type Error**
+```bash
+# Error: Dict entry has incompatible type
+# Solution: Use proper generic types
+results: Dict[str, Any] = {}
+```
+
+### **Performance Optimization**
+```bash
+# Cache MyPy results
+./venv/bin/mypy --incremental apps/coordinator-api/src/app/
+
+# Use daemon mode for faster checking
+./venv/bin/mypy --daemon apps/coordinator-api/src/app/
+
+# Limit scope for large projects
+./venv/bin/mypy apps/coordinator-api/src/app/domain/ --exclude apps/coordinator-api/src/app/domain/legacy/
+```
+
+### **Configuration Issues**
+```bash
+# Check MyPy configuration
+./venv/bin/mypy --config-file pyproject.toml apps/coordinator-api/src/app/
+
+# Show configuration
+./venv/bin/mypy --show-config
+
+# Debug configuration
+./venv/bin/mypy --verbose apps/coordinator-api/src/app/
+```

-# AITBC Setup Guide
-
-## Quick Setup (New Host)
-
-Run this single command on any new host to install AITBC:
-
-```bash
-sudo bash <(curl -sSL https://raw.githubusercontent.com/oib/aitbc/main/setup.sh)
-```
-
-Or clone and run manually:
-
-```bash
-sudo git clone https://gitea.bubuit.net/oib/aitbc.git /opt/aitbc
-cd /opt/aitbc
-sudo chmod +x setup.sh
-sudo ./setup.sh
-```
-
-## What the Setup Script Does
-
-1. **Prerequisites Check**
-   - Verifies Python 3.13.5+, pip3, git, systemd
-   - Checks for root privileges
-
-2. **Repository Setup**
-   - Clones AITBC repository to `/opt/aitbc`
-   - Handles multiple repository URLs for reliability
-
-3. **Virtual Environments**
-   - Creates Python venvs for each service
-   - Installs dependencies from `requirements.txt` when available
-   - Falls back to core dependencies if requirements missing
-
-4. **Runtime Directories**
-   - Creates standard Linux directories:
-     - `/var/lib/aitbc/keystore/` - Blockchain keys
-     - `/var/lib/aitbc/data/` - Database files  
-     - `/var/lib/aitbc/logs/` - Application logs
-     - `/etc/aitbc/` - Configuration files
-   - Sets proper permissions and ownership
-
-5. **Systemd Services**
-   - Installs service files to `/etc/systemd/system/`
-   - Enables auto-start on boot
-   - Provides fallback manual startup
-
-6. **Service Management**
-   - Creates `/opt/aitbc/start-services.sh` for manual control
-   - Creates `/opt/aitbc/health-check.sh` for monitoring
-   - Sets up logging to `/var/log/aitbc-*.log`
-
-## Runtime Directories
-
-AITBC uses standard Linux system directories for runtime data:
-
-```
-/var/lib/aitbc/
-├── keystore/     # Blockchain private keys (700 permissions)
-├── data/         # Database files (.db, .sqlite)
-└── logs/         # Application logs
-
-/etc/aitbc/       # Configuration files
-/var/log/aitbc/   # System logging (symlink)
-```
-
-### Security Notes
-- **Keystore**: Restricted to root/aitbc user only
-- **Data**: Writable by services, readable by admin
-- **Logs**: Rotated automatically by logrotate
-
-## Service Endpoints
-
-| Service | Port | Health Endpoint |
-|---------|------|----------------|
-| Wallet API | 8003 | `http://localhost:8003/health` |
-| Exchange API | 8001 | `http://localhost:8001/api/health` |
-| Coordinator API | 8000 | `http://localhost:8000/health` |
-| Blockchain RPC | 8545 | `http://localhost:8545` |
-
-## Management Commands
-
-```bash
-# Check service health
-/opt/aitbc/health-check.sh
-
-# Restart all services
-/opt/aitbc/start-services.sh
-
-# View logs (new standard locations)
-tail -f /var/lib/aitbc/logs/aitbc-wallet.log
-tail -f /var/lib/aitbc/logs/aitbc-coordinator.log
-tail -f /var/lib/aitbc/logs/aitbc-exchange.log
-
-# Check keystore
-ls -la /var/lib/aitbc/keystore/
-
-# Systemd control
-systemctl status aitbc-wallet
-systemctl restart aitbc-coordinator-api
-systemctl stop aitbc-exchange-api
-```
-
-## Troubleshooting
-
-### Services Not Starting
-1. Check logs: `tail -f /var/lib/aitbc/logs/aitbc-*.log`
-2. Verify ports: `netstat -tlnp | grep ':800'`
-3. Check processes: `ps aux | grep python`
-4. Verify runtime directories: `ls -la /var/lib/aitbc/`
-
-### Missing Dependencies
-The setup script handles missing `requirements.txt` files by installing core dependencies:
-- fastapi
-- uvicorn
-- pydantic
-- httpx
-- python-dotenv
-
-### Port Conflicts
-Services use these default ports. If conflicts exist:
-1. Kill conflicting processes: `kill <pid>`
-2. Modify service files to use different ports
-3. Restart services
-
-## Development Mode
-
-For development with manual control:
-
-```bash
-cd /opt/aitbc/apps/wallet
-source .venv/bin/activate
-python simple_daemon.py
-
-cd /opt/aitbc/apps/exchange
-source .venv/bin/activate
-python simple_exchange_api.py
-
-cd /opt/aitbc/apps/coordinator-api/src
-source ../.venv/bin/activate
-python -m uvicorn app.main:app --host 0.0.0.0 --port 8000
-```
-
-## Production Considerations
-
-For production deployment:
-1. Configure proper environment variables
-2. Set up reverse proxy (nginx)
-3. Configure SSL certificates
-4. Set up log rotation
-5. Configure monitoring and alerts
-6. Use proper database setup (PostgreSQL/Redis)

-# AITBC Blockchain RPC Service Code Map
-
-## Service Configuration
-**File**: `/etc/systemd/system/aitbc-blockchain-rpc.service`
-**Entry Point**: `python3 -m uvicorn aitbc_chain.app:app --host ${rpc_bind_host} --port ${rpc_bind_port}`
-**Working Directory**: `/opt/aitbc/apps/blockchain-node`
-**Environment File**: `/etc/aitbc/blockchain.env`
-
-## Application Structure
-
-### 1. Main Entry Point: `app.py`
-**Location**: `/opt/aitbc/apps/blockchain-node/src/aitbc_chain/app.py`
-
-#### Key Components:
-- **FastAPI App**: `create_app()` function
-- **Lifespan Manager**: `async def lifespan(app: FastAPI)`
-- **Middleware**: RateLimitMiddleware, RequestLoggingMiddleware
-- **Routers**: rpc_router, websocket_router, metrics_router
-
-#### Startup Sequence (lifespan function):
-1. `init_db()` - Initialize database
-2. `init_mempool()` - Initialize mempool
-3. `create_backend()` - Create gossip backend
-4. `await gossip_broker.set_backend(backend)` - Set up gossip broker
-5. **PoA Proposer** (if enabled):
-   - Check `settings.enable_block_production and settings.proposer_id`
-   - Create `PoAProposer` instance
-   - Call `asyncio.create_task(proposer.start())`
-
-### 2. RPC Router: `rpc/router.py`
-**Location**: `/opt/aitbc/apps/blockchain-node/src/aitbc_chain/rpc/router.py`
-
-#### Key Endpoints:
-- `GET /rpc/head` - Returns current chain head (404 when no blocks exist)
-- `GET /rpc/mempool` - Returns pending transactions (200 OK)
-- `GET /rpc/blocks/{height}` - Returns block by height
-- `POST /rpc/transaction` - Submit transaction
-- `GET /rpc/blocks-range` - Get blocks in height range
-
-### 3. Gossip System: `gossip/broker.py`
-**Location**: `/opt/aitbc/apps/blockchain-node/src/aitbc_chain/gossip/broker.py`
-
-#### Backend Types:
-- `InMemoryGossipBackend` - Local memory backend (currently used)
-- `BroadcastGossipBackend` - Network broadcast backend
-
-#### Key Functions:
-- `create_backend(backend_type, broadcast_url)` - Creates backend instance
-- `gossip_broker.set_backend(backend)` - Sets active backend
-
-### 4. Chain Sync System: `chain_sync.py`
-**Location**: `/opt/aitbc/apps/blockchain-node/src/aitbc_chain/chain_sync.py`
-
-#### ChainSyncService Class:
-- **Purpose**: Synchronizes blocks between nodes
-- **Key Methods**:
-  - `async def start()` - Starts sync service
-  - `async def _broadcast_blocks()` - **MONITORING SOURCE**
-  - `async def _receive_blocks()` - Receives blocks from Redis
-
-#### Monitoring Code (_broadcast_blocks method):
-```python
-async def _broadcast_blocks(self):
-    """Broadcast local blocks to other nodes"""
-    import aiohttp
-    
-    last_broadcast_height = 0
-    retry_count = 0
-    max_retries = 5
-    base_delay = 2
-    
-    while not self._stop_event.is_set():
-        try:
-            # Get current head from local RPC
-            async with aiohttp.ClientSession() as session:
-                async with session.get(f"http://{self.source_host}:{self.source_port}/rpc/head") as resp:
-                    if resp.status == 200:
-                        head_data = await resp.json()
-                        current_height = head_data.get('height', 0)
-                        
-                        # Reset retry count on successful connection
-                        retry_count = 0
-```
-
-### 5. PoA Consensus: `consensus/poa.py`
-**Location**: `/opt/aitbc/apps/blockchain-node/src/aitbc_chain/consensus/poa.py`
-
-#### PoAProposer Class:
-- **Purpose**: Proposes blocks in Proof-of-Authority system
-- **Key Methods**:
-  - `async def start()` - Starts proposer loop
-  - `async def _run_loop()` - Main proposer loop
-  - `def _fetch_chain_head()` - Fetches chain head from database
-
-### 6. Configuration: `blockchain.env`
-**Location**: `/etc/aitbc/blockchain.env`
-
-#### Key Settings:
-- `rpc_bind_host=0.0.0.0`
-- `rpc_bind_port=8006`
-- `gossip_backend=memory` (currently set to memory backend)
-- `enable_block_production=false` (currently disabled)
-- `proposer_id=` (currently empty)
-
-## Monitoring Source Analysis
-
-### Current Configuration:
-- **PoA Proposer**: DISABLED (`enable_block_production=false`)
-- **Gossip Backend**: MEMORY (no network sync)
-- **ChainSyncService**: NOT EXPLICITLY STARTED
-
-### Mystery Monitoring:
-Despite all monitoring sources being disabled, the service still makes requests to:
-- `GET /rpc/head` (404 Not Found)
-- `GET /rpc/mempool` (200 OK)
-
-### Possible Hidden Sources:
-1. **Built-in Health Check**: The service might have an internal health check mechanism
-2. **Background Task**: There might be a hidden background task making these requests
-3. **External Process**: Another process might be making these requests
-4. **Gossip Backend**: Even the memory backend might have monitoring
-
-### Network Behavior:
-- **Source IP**: `10.1.223.1` (LXC gateway)
-- **Destination**: `localhost:8006` (blockchain RPC)
-- **Pattern**: Every 10 seconds
-- **Requests**: `/rpc/head` + `/rpc/mempool`
-
-## Conclusion
-
-The monitoring is coming from **within the blockchain RPC service itself**, but the exact source remains unclear after examining all obvious candidates. The most likely explanations are:
-
-1. **Hidden Health Check**: A built-in health check mechanism not visible in the main code paths
-2. **Memory Backend Monitoring**: Even the memory backend might have monitoring capabilities
-3. **Internal Process**: A subprocess or thread within the main process making these requests
-
-### Recommendations:
-1. **Accept the monitoring** - It appears to be harmless internal health checking
-2. **Add authentication** to require API keys for RPC endpoints
-3. **Modify source code** to remove the hidden monitoring if needed
-
-**The monitoring is confirmed to be internal to the blockchain RPC service, not external surveillance.**
