S: I ran a database migration on staging that I thought was prod-safe.
T: It dropped a column other code still used.
A: I immediately told the team, restored from backup, and added the column back
   with a safe migration. Then I documented the rollback steps.
R: No prod impact. Now I always test migrations on a prod-like copy and require
   a second reviewer for schema changes.
