The schema just broke. You need a new column.

When data requirements change, structures must adapt fast. Adding a new column in your database is more than an ALTER TABLE command. It touches performance, migration safety, indexing, application code, and deployment order. Done wrong, it can break production. Done right, it’s invisible to users. First, define the purpose
