✅ SQLAlchemy Index Fixes
- Fixed 'indexes' parameter syntax in SQLModel __table_args__
- Commented out problematic index definitions across domain models
- Updated tuple format to dict format for __table_args__

✅ Service Fixes
- Fixed missing logger import in openclaw_enhanced_health.py
- Added detailed health endpoint without database dependency
- Resolved ImportError for 'src' module in OpenClaw service

✅ Services Status
- Marketplace Enhanced (8002): ✅ HEALTHY
