Term	Kind	Topic	What it is
Command Validity Window Command Expiry, Time-Bounded Actuation	practice	Fleet Management	An expiry attached to a command sent to a device, so that an instruction delivered after the situation has changed is discarded rather than executed.
Device Group Rollout	practice	Fleet Management	Applying configuration or firmware to a fleet in ordered cohorts with health checks between them, because a bad change applied to everything at once has no remedy.
Fleet Management	practice	Fleet Management	Operating a large population of physical devices — knowing what is deployed, where, on which version, in what health, and acting on that at scale.
