Nothing beyond the operator selecting its name. And the same name is used for every tray of that type. I can see why storing more pocket numbers hasn't helped us.

Ask the integrator to define that confirmation before treating either saved position as usable.

We walked it through with our shift lead. A changed source now leaves its position unconfirmed, and a possibly completed transfer leaves both sides for reconciliation. Integrator is turning that into the recovery design; our cover operator still needs to try the handover.
