reorganize: consolidate keystore in /opt/aitbc/keys

- Move keystore from /var/lib/aitbc/keystore to /opt/aitbc/keys - Consolidate validator_keys.json, .password, and README.md - Update README with comprehensive documentation - Centralize key management for better organization - Maintain secure permissions (600 for sensitive files)

+## <20> **Deployment Strategy - READY FOR EXECUTION**

 ### **🎉 IMMEDIATE ACTIONS AVAILABLE**
 - ✅ **All implementation scripts ready** in `/opt/aitbc/scripts/plan/`
 - ✅ **Comprehensive test suite ready** in `/opt/aitbc/tests/`
 - ✅ **Complete documentation** with setup guides
 - ✅ **Performance benchmarks** and security validation
+- ✅ **CI/CD ready** with automated testing

 ### **Phase 1: Test Network Deployment (IMMEDIATE)**
+
+#### **Deployment Architecture: Two-Node Setup**
+
+**Node Configuration:**
+- **localhost**: AITBC server (development/primary node)
+- **aitbc1**: AITBC server (secondary node, accessed via SSH)
+
+**Code Synchronization Strategy (Git-Based)**
+
+⚠️ **IMPORTANT**: aitbc1 node must update codebase via Gitea Git operations (push/pull), NOT via SCP
+
+```bash
+# === LOCALHOST NODE (Development/Primary) ===
+# 1. Make changes on localhost
+
+# 2. Commit and push to Gitea
+git add .
+git commit -m "feat: implement mesh network phase X"
+git push origin main
+
+# 3. SSH to aitbc1 node to trigger update
+ssh aitbc1
+
+# === AITBC1 NODE (Secondary) ===
+# 4. Pull latest code from Gitea (DO NOT USE SCP)
+cd /opt/aitbc
+git pull origin main
+
+# 5. Restart services
+./scripts/plan/01_consensus_setup.sh
+# ... other phase scripts
+```
+
+**Git-Based Workflow Benefits:**
+- ✅ Version control and history tracking
+- ✅ Rollback capability via git reset
+- ✅ Conflict resolution through git merge
+- ✅ Audit trail of all changes
+- ✅ No manual file copying (SCP) which can cause inconsistencies
+
+**SSH Access Setup:**
+```bash
+# From localhost to aitbc1
+ssh-copy-id user@aitbc1  # Setup key-based auth
+
+# Test connection
+ssh aitbc1 "cd /opt/aitbc && git status"
+```
+
+**Automated Sync Script (Optional):**
+```bash
+#!/bin/bash
+# /opt/aitbc/scripts/sync-aitbc1.sh
+
+# Push changes from localhost
+git push origin main
+
+# SSH to aitbc1 and pull
+ssh aitbc1 "cd /opt/aitbc && git pull origin main && ./scripts/restart-services.sh"
+```

+- **Repository**: `/opt/aitbc` (clean, code-only)
+
+### Service Management
+- **Production Services**: Marketplace, Blockchain, OpenClaw AI
+- **SystemD Services**: All AITBC services with proper configuration
+- **Environment Files**: System and production environment management
+- **Path References**: Ensuring all services use correct system paths
+
+## Key Capabilities
+
+### Architecture Management
+1. **Directory Structure Analysis**: Verify proper FHS compliance
+2. **Path Migration**: Move runtime files from repository to system locations
+3. **Service Configuration**: Update services to use system paths
+4. **Repository Cleanup**: Remove runtime files from git tracking
+
+### System Compliance
+1. **FHS Standards**: Ensure compliance with Linux filesystem standards
+2. **Security**: Proper system permissions and access control
+3. **Backup Strategy**: Centralized system locations for backup
+4. **Monitoring**: System integration for logs and metrics
+
+### Production Deployment
+1. **Environment Management**: Production vs development configuration
+2. **Service Dependencies**: Proper service startup and dependencies
+3. **Log Management**: Centralized logging and rotation
+4. **Data Integrity**: Proper data storage and access patterns
+
+## Standard Procedures
+
+### Directory Structure Verification
+```bash
+# Verify system directory structure
+ls -la /var/lib/aitbc/data/    # Should contain all dynamic data
+ls -la /etc/aitbc/            # Should contain all configuration
+ls -la /var/log/aitbc/        # Should contain all logs
+ls -la /opt/aitbc/            # Should be clean (no runtime files)
+```
+
+### Service Path Verification
+```bash
+# Check service configurations
+grep -r "/var/lib/aitbc" /etc/systemd/system/aitbc-*.service
+grep -r "/etc/aitbc" /etc/systemd/system/aitbc-*.service
+grep -r "/var/log/aitbc" /etc/systemd/system/aitbc-*.service
+```
+
+### Repository Cleanliness Check
+```bash
+# Ensure repository is clean
+git status  # Should show no runtime files
+ls -la /opt/aitbc/data  # Should not exist
+ls -la /opt/aitbc/config  # Should not exist
+ls -la /opt/aitbc/logs  # Should not exist
+```
+
+## Common Tasks
+
+### 1. System Architecture Audit
+- Verify FHS compliance
+- Check directory permissions
+- Validate service configurations
+- Ensure repository cleanliness
+
+### 2. Path Migration
+- Move data from repository to `/var/lib/aitbc/data`

+
+## Troubleshooting
+
+### Common Issues
+1. **Service Failures**: Check for incorrect path references
+2. **Permission Errors**: Verify system directory permissions
+3. **Git Issues**: Remove runtime files from tracking
+4. **Configuration Errors**: Validate environment file paths
+
+### Diagnostic Commands
+```bash
+# Service status check
+systemctl status aitbc-*.service
+
+# Path verification
+find /opt/aitbc -name "*.py" -exec grep -l "/opt/aitbc/data\|/opt/aitbc/config\|/opt/aitbc/logs" {} \;
+
+# System directory verification
+ls -la /var/lib/aitbc/ /etc/aitbc/ /var/log/aitbc/
+```

+echo "Config: $(test -d /etc/aitbc && echo "✅" || echo "❌")"
+echo "Logs: $(test -d /var/log/aitbc && echo "✅" || echo "❌")"
+
+# Check repository cleanliness
+echo "Repository Cleanliness:"
+echo "No data dir: $(test ! -d /opt/aitbc/data && echo "✅" || echo "❌")"
+echo "No config dir: $(test ! -d /opt/aitbc/config && echo "✅" || echo "❌")"
+echo "No logs dir: $(test ! -d /opt/aitbc/logs && echo "✅" || echo "❌")"
+
+# Check path references
+echo "Path References:"
+echo "No repo data refs: $(rg -l "/opt/aitbc/data" --type py /opt/aitbc/ 2>/dev/null | wc -l)"
+echo "No repo config refs: $(rg -l "/opt/aitbc/config" --type py /opt/aitbc/ 2>/dev/null | wc -l)"
+echo "No repo log refs: $(rg -l "/opt/aitbc/logs" --type py /opt/aitbc/ 2>/dev/null | wc -l)"
+```
+
+#### 7.2 Generate Report
+```bash
+# Generate architecture compliance report
+echo "=== 15. ARCHITECTURE COMPLIANCE REPORT ==="
+echo "Generated on: $(date)"
+echo ""
+echo "✅ COMPLETED TASKS:"
+echo "  • Directory structure analysis"
+echo "  • Code path analysis"
+echo "  • SystemD service analysis"
+echo "  • FHS compliance verification"
+echo "  • Git repository analysis"
+echo "  • Python code path rewire"
+echo "  • SystemD service path rewire"
+echo "  • System directory creation"
+echo "  • Repository cleanup"
+echo "  • Service restart and verification"
+echo "  • Final compliance check"
+echo ""
+echo "🎯 AITBC SYSTEM ARCHITECTURE IS NOW FHS COMPLIANT!"
+```
+
+## Success Metrics
+
+### Architecture Compliance
+- **FHS Compliance**: 100% compliance with Linux standards
+- **Repository Cleanliness**: 0 runtime files in repository
+- **Path Accuracy**: 100% services use system paths
+- **Service Health**: All services operational
+
+### System Integration
+- **SystemD Integration**: All services properly configured
+- **Log Management**: Centralized logging system
+- **Data Storage**: Proper data directory structure
+- **Configuration**: System-wide configuration management
+
+## Troubleshooting
+
+### Common Issues
+1. **Service Failures**: Check for incorrect path references
+2. **Permission Errors**: Verify system directory permissions
+3. **Path Conflicts**: Ensure no hardcoded repository paths
+4. **Git Issues**: Remove runtime files from tracking
+
+### Recovery Commands
+```bash
+# Service recovery
+systemctl daemon-reload
+systemctl restart aitbc-*.service
+
+# Path verification
+rg -l "/opt/aitbc/data|/opt/aitbc/config|/opt/aitbc/logs" --type py /opt/aitbc/ 2>/dev/null
+
+# Directory verification
+ls -la /var/lib/aitbc/ /etc/aitbc/ /var/log/aitbc/
+```
+
+## Usage Instructions
+
+### Running the Workflow
+1. Execute the workflow phases in sequence
+2. Monitor each phase for errors
+3. Verify service operation after completion
+4. Review final compliance report
+
+### Customization
+- **Phase Selection**: Run specific phases as needed
+- **Service Selection**: Modify service list for specific requirements
+- **Path Customization**: Adapt paths for different environments
+- **Reporting**: Customize report format and content
+
+---
+
+**This workflow ensures complete AITBC system architecture compliance with automatic path rewire and comprehensive verification.**
