+The launcher summary counts the number of times each worker was launched, and it shows the total number of assigned and completed tasks from all past terminated instances of each worker. In addition, it shows whether the current worker instance was actively connected ("online") or had connected at some point during its life cycle ("discovered") as of the last call to `controller$launcher$tally()`.
