This object reports the same kind of software workflow state as the chassis-wide object, but scoped to one individual module. On a multi-module chassis undergoing a staged upgrade rollout, this lets an admin confirm that each line card is progressing through downloading, installing, and activating independently, catching a card that's stuck at one stage while its siblings have already moved on. For example, one module reporting validating while every other module already reports running would flag that specific card as the one holding up completion of the rollout.
