A dashboard that watches engineering activity can tell you the system is overloaded, or it can tell you someone is slacking. The columns are identical. The claims are not. This is a post about the one rule that separates the two, and why most engineering monitoring quietly crosses the line.

Every observability tool for agents can show you a thousand spans. Not one of them can point at the sentence that caused the failure. This post is about the missing discipline of failure attribution.
