The first pass anchored a slice on the active task, which still showed completed rows, kept the active item mid-window, and gave the two views divergent selection logic. Per reviewer, replace it with one shared policy both collapsed views run.
selectCollapsedTodos (todo.ts) omits completed/abandoned, pulls every active task (in_progress or subagent-matched pending) to the head in todo order, fills remaining rows with following pending tasks, and emits '… N more active todos' when active work alone exceeds the cap; it falls back to closed tasks for a settled phase so HUD persistence still renders. renderTreeList gains a trailingSummary primitive so item selection lives in the todo domain. The transient tool result reaches live subagent matches via setActiveTodoDescriptionsProvider, wired from interactive mode's observer registry, so both views share the active set.
