- Add backend/app/core/scheduler.py with AsyncIOScheduler, CronTrigger-based job registration, and _fire_maintenance_schedule to create batch sessions - Wire scheduler.start()/load_all_schedules()/shutdown() into main.py lifespan - Call register_schedule() in create_schedule endpoint after commit - Call register_schedule()/unregister_schedule() in update_schedule based on is_active - Add TreeShare to models/__init__.py so all SQLAlchemy mapper relationships resolve before ORM queries in the scheduler context Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
