You are modifying a database schema. Migrations are hard to reverse in production — verify before writing.

check

Before writing this migration: - Have you read the current schema (not assumed it)? - Is this migration reversible? If not, does it need to be? - What existing data is affected — will this migration need a data backfill? - Are there other services or queries that depend on the table/column being changed? - Is there a migration naming convention or ordering system in this project?
