🔧 SERVER-SIDE FIXES APPLIED

Database Configuration Fix:

# 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):

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):

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:

# Initial release
✅ GPU gpu_c72b40d2 released
✅ Status: available

2. GPU Booking Test:

# Book GPU
✅ {"booking_id":"bk_e062b4ae72","status":"booked","total_cost":1.5}
✅ GPU status: booked

3. GPU Release Test:

# Release GPU
✅ {"status":"released","gpu_id":"gpu_c72b40d2","refund":0.0}
✅ GPU status: available

🔍 TECHNICAL DETAILS

Root Cause Resolution:

# 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:

# BEFORE: Wrong path
"sqlite:////home/oib/windsurf/aitbc/apps/coordinator-api/aitbc_coordinator.db"

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

Service Integration:

# 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
