B.5.TU:4.5 - Apply the answer to the working question

Read the answer back in the terms of the intended use. If it gives a construction, determine whether the required inputs and operations are available. If it gives a bound, use the exclusion or allowance that bound supports. If it gives a physical prediction, identify the model and operating conditions under which that prediction concerns the system.

Examine the correspondence at the point where it could change the action. Does a feasible mathematical answer violate a receiving condition? Could two cases treated alike by the formulation require different actions? If so, restore the distinction, change the formulation, or keep a weaker answer that remains useful.

For a new physical reliance, address the model assumptions whose failure could change that use. Reuse adequate knowledge and observations. Choose further checking or acquisition under C.11.DUA when their benefit and burden are the live decision; an unresolved stronger claim need not displace a sufficient conditional answer.
