Structural repairs need a clear closure standard. First define which cross-checked results of VIN history, physical vehicle inspection, title documents, and maintenance records constitute completion, then specify who reviews them and how exceptions are recorded. Without a closure standard, teams can mistake "a response was received" for "the issue is resolved." This is why vehicle history, mileage, or structural condition that cannot be proven by a single photograph is often carried into the next stage.
