The original title is "Why the Same Bug Keeps Coming Back - And How to Stop It"

Short summary

A developer recounts fixing the same bug across multiple copy-pasted query handlers in a multi-tenant SaaS. The lesson: bugs appear as individual tickets but often stem from broken patterns. The fix is to describe the violated rule in searchable language, grep for all instances, and patch them in one PR rather than fixing one-off.

• •Bugs surface as individual tickets but often share a common broken pattern
• •Describe the violated rule in plain, searchable language before fixing
• •Grep for all instances and fix them in the same PR, not as follow-ups
