## Task Status Information
This section defines the possible task status values returned by the API when polling for task completion.

### Completed Task Statuses (Polling can stop)
These indicate that the task has reached a terminal state — either success or failure. Once any of these is received, polling should stop.
- task_postprocess_end : Task completed successfully and post-processing is done.
- task_cancel : Task was cancelled by the user or system.

### Running Task Statuses (Continue polling)
These statuses indicate that the task is still in progress. Polling should continue if one of these is returned.
- task_queue : Task is waiting in the queue.
- task_accept : Task has been accepted for processing.
- task_assign : Task is being assigned to a worker.
- task_preprocess_start : Preprocessing is starting.
- task_preprocess_end : Preprocessing is complete.
- task_start : Task execution has started.
- task_output : Output is being generated.
