# AITBC Codebase Update Summary - Service Standardization

## Overview
This document summarizes the comprehensive service standardization and cleanup performed on the AITBC codebase to ensure all services use the standardized `/opt/aitbc` paths and `aitbc` user configuration.

## Date of Update
**March 4, 2026**

## Services Standardized

### ✅ Core Services (Fully Operational)
- **`aitbc-blockchain-node.service`** - RUNNING (52.5M memory)
- **`aitbc-blockchain-rpc.service`** - RUNNING (55.3M memory)  
- **`aitbc-coordinator-api.service`** - RUNNING (27.9M memory)
- **`aitbc-exchange-api.service`** - RUNNING (9.8M memory)

### ✅ Standardized Configuration Applied

#### User Standardization
- **All services**: Now use `aitbc` user (instead of `root`, `oib`, `debian`, etc.)
- **Consistent permissions**: Proper ownership of `/opt/aitbc` directories

#### Path Standardization  
- **Working directories**: All use `/opt/aitbc/apps/{service-name}` structure
- **Virtual environments**: All use `/opt/aitbc/apps/coordinator-api/.venv/bin/python`
- **Log directories**: All use `/opt/aitbc/logs/`
- **Data directories**: All use `/opt/aitbc/data/`

#### Python Version Standardization
- **Minimum version**: Python 3.13.5+ enforced across all services
- **Consistent validation**: Pre-execution version checks

## Services Cleaned Up (Duplicates Removed)

### ❌ Removed Duplicate Services
- **`aitbc-node.service`** - Removed (duplicate of blockchain-node)
- **`aitbc-gpu-miner-root.service`** - Removed (duplicate of gpu-miner)
- **`aitbc-host-gpu-miner.service`** - Removed (broken configuration)
- **`aitbc-blockchain-rpc-1.service`** - Purged (stubborn systemd reference)
- **`aitbc-blockchain-rpc-2.service`** - Purged (stubborn systemd reference)

### ✅ Service Renames
- **`aitbc-gpu-multimodal.service`** → **`aitbc-multimodal-gpu.service`** (better naming)

## Environment-Specific Configuration

### AT1 (Localhost) Environment
- **GPU Services**: `aitbc-multimodal-gpu.service` ENABLED
- **CPU Services**: `aitbc-multimodal.service` DISABLED
- **Reasoning**: AT1 has GPU resources for development

### Production Servers Environment  
- **GPU Services**: `aitbc-multimodal-gpu.service` DISABLED
- **CPU Services**: `aitbc-multimodal.service` ENABLED
- **Reasoning**: Production optimized for CPU processing

## File Organization Updates

### Scripts Reorganized
- **App-specific scripts**: Moved from `/scripts/` to `/apps/{app}/scripts/`
- **Development scripts**: Moved to `/dev/scripts/`
- **Deployment scripts**: Consolidated in `/scripts/deploy/`
- **Global scripts**: Only truly global utilities remain in `/scripts/`

### Key Moves
- **`geo_load_balancer.py`** → `/apps/coordinator-api/scripts/`
- **Blockchain scripts** → `/apps/blockchain-node/scripts/`
- **Contract scripts** → `/contracts/scripts/`
- **Development tools** → `/dev/scripts/`

## Deployment Automation

### New Deployment Scripts
- **`deploy-multimodal-services.sh`** - Environment-aware multimodal deployment
- **Updated deployment logic** - Automatic configuration based on target environment
- **Standardized paths** - All deployments use `/opt/aitbc` structure

### Environment Detection
```bash
# AT1 (localhost) - GPU services only
./scripts/deploy/deploy-multimodal-services.sh at1

# Production servers - CPU services only  
./scripts/deploy/deploy-multimodal-services.sh server

# Both services (for testing)
./scripts/deploy/deploy-multimodal-services.sh both
```

## Monitoring and Management

### Service Monitoring Workflow
- **Created**: `/scripts/monitor-services.sh` for health checks
- **Created**: `.windsurf/workflows/aitbc-services-monitoring.md` workflow
- **Automated**: Systemd timer for 5-minute health checks
- **Comprehensive**: Status reporting and troubleshooting guides

## Documentation Updates

### Updated Documentation
- **Multimodal Services Deployment Guide** - Environment-specific instructions
- **Service Monitoring Workflow** - Complete management procedures
- **Project Organization** - Clean file structure guidelines
- **Development Guidelines** - Updated best practices

### Configuration Examples
- **Service templates** - Standardized service file formats
- **Environment variables** - Consistent naming conventions
- **Security settings** - Proper systemd configurations

## Current Service Status

### ✅ Running Services (4/4 Core)
```bash
● aitbc-blockchain-node.service      active running (52.5M memory)
● aitbc-blockchain-rpc.service       active running (55.3M memory)
● aitbc-coordinator-api.service      active running (27.9M memory)
● aitbc-exchange-api.service         active running (9.8M memory)
```

### ✅ Standardized Non-Core Services
```bash
● aitbc-exchange-frontend.service   standardized (aitbc user, /opt/aitbc paths)
● aitbc-explorer.service            standardized (aitbc user, /opt/aitbc paths)
● aitbc-wallet.service              standardized (aitbc user, /opt/aitbc paths)
● aitbc-gpu-registry.service         standardized (aitbc user, /opt/aitbc paths)
```

### ⚠️ Services in Restart Loop (2)
- `aitbc-loadbalancer-geo.service` 
- `aitbc-marketplace-enhanced.service`

### ✅ Disabled Services (Environment-specific)
- `aitbc-multimodal.service` (disabled on AT1, enabled on servers)
- `aitbc-multimodal-gpu.service` (ready to run)

## Benefits Achieved

### 🎯 Standardization Benefits
- **Consistent user**: All services use `aitbc` user
- **Consistent paths**: All use `/opt/aitbc` structure  
- **Consistent Python**: All require 3.13.5+
- **Consistent security**: Proper systemd settings
- **Consistent logging**: Centralized in `/opt/aitbc/logs/`

### 🚀 Operational Benefits
- **No duplicates**: Clean service landscape
- **Environment-aware**: Automatic configuration
- **Monitoring**: Automated health checks
- **Documentation**: Complete guides and workflows
- **Maintainability**: Easier service management

3. **Health metrics** - Detailed performance monitoring
4. **Backup automation** - Automated configuration backups

## Verification Commands

### Check Service Status
```bash
# All AITBC services
systemctl list-units --type=service | grep aitbc

# Core services status
systemctl status aitbc-blockchain-node.service aitbc-blockchain-rpc.service aitbc-coordinator-api.service aitbc-exchange-api.service

# Environment-specific services
systemctl status aitbc-multimodal.service aitbc-multimodal-gpu.service
```

### Verify Standardization
```bash
# Check user consistency
grep -r "User=" /etc/systemd/system/aitbc-*.service | sort | uniq -c

# Check path consistency  
grep -r "WorkingDirectory=" /etc/systemd/system/aitbc-*.service | grep -v "/opt/aitbc"

# Check Python version
grep -r "Python 3.13.5" /etc/systemd/system/aitbc-*.service
```

### Verify File Organization
```bash
# Check script organization
ls -la /opt/aitbc/apps/*/scripts/
ls -la /dev/scripts/
ls -la /scripts/deploy/

# Check for duplicates
find /etc/systemd/system/ -name "*aitbc*" | sort
```

## Summary
