Let's hear about when these "magical" coding assistants actually burned you in production. Copilot, ChatGPT, Claude, whatever - what's the worst bug that made it past review and how much damage did it do?<p>Bonus points for security vulnerabilities and midnight incident reports.
Used Copilot to write a user auth migration script. It silently reset 2FA settings for ~3k users with OAuth accounts because it didn't handle NULL vs empty string edge cases in our legacy DB schema. Classic "garbage in, garbage out" situation.<p>Found out two weeks later when angry users couldn't log in during peak hours. Damage: 4 hours of downtime, one very grumpy security team, and a new "no AI for auth code" policy.
