Multi-select state for bulk task operations on the Dashboard.

Source: hooks/commits/useTaskSelection.ts

The useTaskSelection hook manages multi-select state for bulk task operations on the Dashboard commits screen.

---

Selection State

The hook maintains a Set of selected task IDs internally, exposing it as a stable array for React rendering:

const [selectedIds, setSelectedIds] = useState<Set<string>>(new Set());

---

Available Actions

Action	Behavior
toggleSelect(id)	Adds or removes a task from the selection set
selectAll(tasks)	Adds all visible task IDs to the selection set
clearSelection()	Empties the selection set and exits multi-select mode
bulkDelete()	Iterates through selected IDs, calling deleteTask() via Triple-Write for each

---

Multi-Select Mode

The Dashboard enters multi-select mode when the user long-presses a task card. Visual indicators (checkmarks, highlighted backgrounds) appear on selected items. The mode exits automatically when the selection is cleared or all selected tasks are deleted.

---

Bulk Delete Strategy

Bulk deletion iterates through the selected IDs sequentially (not in parallel) to avoid overwhelming the SyncLock. Each deletion goes through the full Triple-Write pipeline:

for (const id of selectedIds) {
  await deleteTask(id);  // Convex → SQLite → Re-arm alarms
}

Sequential execution ensures each deletion’s rollback can complete before the next starts.
