Asked about Debugging systematically

Walk me through how you debug something.

An answer that works

Reproduce it reliably first. Then one hypothesis at a time, choosing the cheapest experiment that could falsify it rather than confirm it. Bisect the pipeline to eliminate half the system per check rather than inspecting sequentially.

Reading an answer is not being able to give one. The section that teaches this is Debugging systematically, 5 hours of Debugging.
