wp-background-processing

Use when a WordPress plugin needs to run work outside the HTTP request cycle — scheduling async or recurring jobs with Action Scheduler (as_enqueue_async_action, as_schedule_single_action, as_schedule_recurring_action, as_unschedule_action), implementing WP_Background_Process (push_to_queue, save, dispatch, is_queue_empty), registering WP Cron events (wp_schedule_event, wp_clear_scheduled_hook), batch-processing large datasets without hitting PHP timeouts, tracking job progress, handling retries on failure, or debugging the actionscheduler_actions table. Triggers: \"schedule this for later\", \"run this without hitting timeout\", \"queue these items for background processing\", \"why is my cron not running\", \"Action Scheduler job keeps failing\", \"as_enqueue_async_action\", \"WP_Background_Process\", \"push_to_queue\", \"dispatch the queue\", \"DISABLE_WP_CRON\", \"process records in batches\", \"send emails in the background\", \"WP Cron not firing\", \"batch import without timeout\", \"scheduled action not running\", \"background job stuck\", \"wp action-scheduler list\", \"recurring cron event\", \"progress tracking for batch job\", \"retry failed background tasks\", \"chunked processing to avoid timeout\", \"scheduled action completes but nothing happens\", \"my hook never fires in cron\", \"handler registered behind is_admin\", \"job runs in admin but not from cron\", \"webhook fired twice\", \"background job double-processed\", \"make my background job idempotent\". Not for: real-time AJAX handlers or synchronous REST endpoints.
