- Fix useElapsedTimer to use completedAt instead of Date.now() for
finished runs, preventing wildly inaccurate durations (e.g. 9802m)
when reopening old sessions
- Extract formatElapsedMs as a shared pure formatter; reuse in
SubagentActivityCard
- Standardize icon column alignment across all activity row types
using consistent w-4 + h-[18px] icon containers
- Redesign collapsed header: status dot with pulse animation, bolder
status label, tabular-nums on elapsed time, cleaner hierarchy
- Polish expanded stream: timeline spine connecting activity items,
more prominent intent dividers with pill-style background,
tightened vertical rhythm
- Add unit tests for formatElapsedMs

Add multi-select mode to the sidebar session list, enabling users to
archive, restore, or delete multiple sessions at once.
UX:
- Ctrl+Click (Cmd+Click on Mac) any session to enter multi-select mode
- Animated checkboxes stagger-reveal across all visible sessions
- Click to toggle, Shift+Click for range selection
- Running sessions are excluded from selection (safety guard)
- Floating action bar slides up with count pill, Archive, Delete, Cancel
- Batch delete shows a confirmation dialog with hold-to-confirm for 3+
sessions and a scrollable list of session titles
- Batch archive shows an undo toast with 5-second auto-dismiss
- Escape key or Cancel button exits multi-select mode
Backend:
- batchSetSessionsArchived IPC: single load/mutate/persist cycle for N
sessions instead of N sequential calls
- batchDeleteSessions IPC: parallel cleanup of scratchpad dirs and SDK
sessions, then single workspace persist
Accessibility:
- Action bar: role=toolbar, aria-label
- Checkboxes: role=checkbox, aria-checked, keyboard-activatable
- Selection count: aria-live=polite
- Delete dialog: role=alertdialog, aria-modal, focus trap

- Show agent activity label in chat header (Thinking…, Using bash…, etc.)
instead of an anonymous pulsing dot
- Fix ThinkingProcess elapsed timer to tick live every second using
useElapsedTimer hook instead of stale useMemo computation
- Show completed/failed subagents for 3s grace period with fade-out
transition instead of instantly hiding them
- Transition activity labels to Completed state for 1.5s grace period
on session idle instead of abrupt removal
- Eliminate message flash during thinking reclassification by folding
trailing pending assistant messages into the thinking group
optimistically when they follow existing thinking messages
- Stabilize ThinkingProcess isActive flag by checking for pending
messages in the group rather than relying solely on array position
- Skip rendering empty pending messages inside ThinkingProcess steps
