## Critical Model/Database Sync Fix
**Problem**: Railway database has access_url_name/display_url_name columns but Django model didn't define them.
**Solution**:
✅ Add missing fields to Agent model with proper Django field definitions
✅ Create fake migration to sync with existing Railway database schema
✅ Avoid DuplicateColumn errors on Railway deployment
## Changes Made
**Agent Model** ():
- Added
- Added
**Migration** ():
- Fake migration that does nothing (columns already exist on Railway)
- Marks migration as applied without attempting to create existing columns
## Error Fixed
❌ Was: Invalid field name(s) for model Agent: 'access_url_name', 'display_url_name'
✅ Now: Model defines fields that match existing Railway database columns
## Result
- Django model matches Railway PostgreSQL schema
- Agent creation commands will work (fields are now valid)
- populate_agents will succeed and create all 5 agents
- Railway marketplace will finally show agents
