Insight Machine Group Editor — Target Agent Version is now a dropdown populated from the appliance's available agent versions (sorted newest first, with the active version badged); when a pinned version is no longer present in the appliance archive a red "missing from archive" warning surfaces so operators can spot stale pins
Staggered Rollout Controls on the Insight Machine Group Editor — when a Target Agent Version is pinned, a new sub-block exposes Immediate / Gradual / Paused rollout modes (default Gradual), batch size, batch interval, an estimated time-to-roll-out hint, and a Pause/Resume button that toggles between Gradual and Paused without clearing the pinned version
Live Rollout Status Panel on the Insight Machine Group Editor — read-only panel showing started timestamp, offered/total agents, completed count and ETA, with a manual Refresh button; the panel hides gracefully on appliances that don't yet expose rollout status
