Objective

Implement proper database migration system using Alembic for schema version control.

Current Issues

• No database migrations
• Schema changes require manual SQL
• No way to track database version
• Can't rollback schema changes
• Production deployments risky

Expected Outcome

• Alembic migration system setup
• Initial migration capturing current schema
• Migration commands documented
• Safe schema evolution process
• Version control for database

Files to Create

1. /backend/alembic.ini - Alembic configuration
2. /backend/alembic/env.py - Alembic environment
3. /backend/alembic/versions/001_initial_schema.py - Initial migration
4. /backend/migrations/README.md - Migration guide

Implementation Approach

1. Install Alembic: pip install alembic
2. Initialize Alembic: alembic init alembic
3. Configure alembic.ini with database URL from config
4. Set up env.py to use SQLModel metadata
5. Generate initial migration from existing models
6. Document migration commands

Success Criteria

• Alembic configured and working
• Initial migration captures all tables
• Can generate new migrations
• Can upgrade/downgrade database
• Migration guide documented
