Collapsible rows are the v1-schema equivalent: one open, the rest collapsed, same as a tab strip behaviourally. 'activity' is a fourth row for the five panels that are neither cost, resource health, nor subagent-specific (agent count, turn count, code/config-size trends) — left expanded so the dashboard opens on something besides a wall of accordion headers.",
