3. **✅ Service Updated**: Coordinator API restarted with new code
4. **✅ Testing Passed**: GPU release functionality working perfectly

---

## 🔧 **SERVER-SIDE FIXES APPLIED**

### **Database Configuration Fix:**
```python
# Fixed /opt/aitbc/apps/coordinator-api/src/app/database.py
def init_db():
    """Initialize database by creating tables"""
    create_db_and_tables()

# Fixed database path
"sqlite:///./data/coordinator.db"
```

### **Service Configuration:**
- **Working Directory**: `/opt/aitbc/apps/coordinator-api`
- **Database Path**: `/opt/aitbc/apps/coordinator-api/data/coordinator.db`
- **Service Status**: ✅ Active and running

---

## 🧪 **SERVER TESTING RESULTS**

### **Before Fix (Server):**
```bash
curl -X POST "http://localhost:8000/v1/marketplace/gpu/gpu_c72b40d2/release"
❌ HTTP 500 Internal Server Error
❌ AttributeError: total_cost
❌ Service failing to start
```

### **After Fix (Server):**
```bash
curl -X POST "http://localhost:8000/v1/marketplace/gpu/gpu_c72b40d2/release"
✅ HTTP 200 OK
✅ {"status":"released","gpu_id":"gpu_c72b40d2","refund":0.0,"message":"GPU gpu_c72b40d2 released successfully"}
```

---

### **Complete Cycle Test (Server):**

#### **1. GPU Release Test:**
```bash
# Initial release
✅ GPU gpu_c72b40d2 released
✅ Status: available
```

#### **2. GPU Booking Test:**
```bash
# Book GPU
✅ {"booking_id":"bk_e062b4ae72","status":"booked","total_cost":1.5}
✅ GPU status: booked
```

#### **3. GPU Release Test:**
```bash
# Release GPU
✅ {"status":"released","gpu_id":"gpu_c72b40d2","refund":0.0}
✅ GPU status: available
```

## 🔍 **TECHNICAL DETAILS**

### **Root Cause Resolution:**
```python
# BEFORE: SQLModel syntax with SQLAlchemy sessions
gpus = session.exec(stmt).scalars().all()  # ❌ AttributeError

# AFTER: SQLAlchemy syntax with SQLAlchemy sessions  
gpus = session.execute(stmt).scalars().all()  # ✅ Working
```

### **Database Path Fix:**
```python
# BEFORE: Wrong path
"sqlite:////home/oib/windsurf/aitbc/apps/coordinator-api/aitbc_coordinator.db"

# AFTER: Correct persistent path
"sqlite:///./data/coordinator.db"
```

### **Service Integration:**
```bash
# Fixed init_db.py to work with async init_db function
# Fixed database.py to include init_db function
# Fixed service to use correct working directory
```
