A repeatable debugging method
Describe what "The debugging screen is the heart of this loop" changes in practice.
Step 1 of 3
The debugging screen is the heart of this loop. Cursor isn't checking whether you've seen this exact bug - it's checking whether you have a method that gets to the bottom of a bug nobody has seen yet.
A Product Quality Engineer is the senior escalation point between front-line support and engineering. The thing that makes that job possible is a loop you can run on any failure, on an AI-native desktop app whose behavior shifts as models change week to week. Memorized fixes rot. A method doesn't.
Carry one loop into the room and run it out loud. Here it is end to end.
