Manual migration workflow for Major Domo database:

1. Create SQL file in migrations/ with timestamp: YYYY-MM-DD_description.sql
2. Update Peewee model in app/db_engine.py to match
3. Apply via SSH to dev server (10.10.0.42):
   ssh 10.10.0.42 "docker exec -i sba_postgres psql -U sba_admin -d sba_master -c 'SQL HERE'"
4. Production is on Akamai Linode (ssh akamai, cd container-data/sba-database)

Key gotchas:
- Table names are SINGULAR (team, player, etc.) not plural
- Container name is sba_postgres (underscore, not hyphen)
- No psql on local machine - must SSH and use docker exec
- Use IF NOT EXISTS for idempotent migrations
- Peewee FloatField maps to PostgreSQL REAL type
