+"""TaskRepository - an object-shaped, atomic-write-backed facade over
+``core/tasks.py`` (R07-T01).
+
+``core/tasks.py``'s module-level functions (``list_tasks``, ``load_task``,
+``save_task``, ``delete_task``, ``new_task``, ``duplicate_task``) are still
+what every existing call site (``core/task_scheduler.py``,
+``core/task_executors.py``, ``ui/schedule_task_tab.py``) uses, and stay that
+way - ``save_task`` now writes through :func:`atomic_write.write_json`
+itself (R07-T01, same class of durability fix already applied to
+``core/projects.py``/``core/history.py`` at R06-T02), so the fix applies
+whether or not a caller ever touches this class.
+
+This repository exists for the application layer
+(``application/scheduling``, R07-T04) to depend on an interface instead of
+reaching into ``core/`` directly. It is a thin pass-through today, not a
+re-implementation: same on-disk format, same directory, same functions
+underneath.
