My router logged which engine each job went to, then froze that row at dispatch time. The log could say what was decided and never whether it worked. A reconcile command now reads jobs back from the live backends and settles each one to running, completed, failed, or unknown. It refuses to guess in two places. A job missing from a bounded recent window settles to unknown, because absence is equally consistent with finished, crashed at startup, and never started. A healthy job I stopped by hand is unknown too, not failed, since whether the route was right is a separate question. A fabricated completed would corrupt exactly the routing data the log exists to produce.
