Use when restoring a task, deployment or CI/build run that has actually stalled or is failing: a promised fix still fails, a call is refused, a tool fails to launch, a tool adapter fails before execution, authority is missing, a runner hits a resource limit, a wrapper or test timeout leaves no compiler or assertion output, publication stalls inside a pre-push guard, a queue/review stops progressing, a pull request has no CI run after a push, a completion watch stays pending after its target finishes, or an environment disappears with unpushed work. Use prove-it and challenge for attribution of a past failure without restoration. A job making normal progress or waiting within its documented external cycle needs no intervention.
