The Legacy Ticket

Leo, a backend developer, was woken up by a PagerDuty alert at 2:00 AM. A client’s internal dashboard—built in 2018 and running on a legacy CMS—had completely broken. The error logs pointed to a strange conflict: the current jQuery version (3.4.0) was misbehaving with a new security header their IT team had deployed. The client was back online
