- Extract COMPLETE_STATUSES as a class constant on PaperlessTask,
eliminating the repeated status tuple across models.py, views.py (3×),
and filters.py
- Extract _CELERY_STATE_TO_STATUS as a module-level constant instead of
rebuilding the dict on every task_postrun
- Extract _V9_TYPE_TO_TRIGGER_SOURCE and _RUNNABLE_TASKS as class
constants on TasksViewSet instead of rebuilding on every request
- Extract _TRIGGER_SOURCE_TO_V9_TYPE as a class constant on
TaskSerializerV9 instead of rebuilding per serialized object
- Extract _get_consume_args helper to deduplicate identical arg
extraction logic in _extract_input_data, _determine_trigger_source,
and _extract_owner_id
- Move inline imports (re, traceback) and Avg to module level
- Fix _DOCUMENT_SOURCE_TO_TRIGGER type annotation key type to
DocumentSource instead of Any
- Remove redundant truthiness checks in SystemStatusView branches
already guarded by an is-None check
