+    Three mechanisms prevent queue runaway:
+
+    1. **Queue depth backpressure** – if the broker queue already has more than
+       USER_FILE_PROCESSING_MAX_QUEUE_DEPTH items we skip this beat cycle
+       entirely.  Workers are clearly behind; adding more tasks would only make
+       the backlog worse.
+
+    2. **Per-file queued guard** – before enqueuing a task we set a short-lived
+       Redis key (TTL = CELERY_USER_FILE_PROCESSING_TASK_EXPIRES).  If that key
+       already exists the file already has a live task in the queue, so we skip
+       it.  The worker deletes the key the moment it picks up the task so the
+       next beat cycle can re-enqueue if the file is still PROCESSING.
+
+    3. **Task expiry** – every enqueued task carries an `expires` value equal to
+       CELERY_USER_FILE_PROCESSING_TASK_EXPIRES.  If a task is still sitting in
+       the queue after that deadline, Celery discards it without touching the DB.
+       This is a belt-and-suspenders defence: even if the guard key is lost (e.g.
+       Redis restart), stale tasks evict themselves rather than piling up forever.

+External dependency unit tests for user file processing queue protections.

+Verifies that the three mechanisms added to check_user_file_processing work
+correctly:
+
+1. Queue depth backpressure – when the broker queue exceeds
+   USER_FILE_PROCESSING_MAX_QUEUE_DEPTH, no new tasks are enqueued.
+
+2. Per-file Redis guard key – if the guard key for a file already exists in
+   Redis, that file is skipped even though it is still in PROCESSING status.
+
+3. Task expiry – every send_task call carries expires=
+   CELERY_USER_FILE_PROCESSING_TASK_EXPIRES so that stale queued tasks are
+   discarded by workers automatically.
+
+Also verifies that process_single_user_file clears the guard key the moment
+it is picked up by a worker.
+
+Uses real Redis (DB 0 via get_redis_client) and real PostgreSQL for UserFile
+rows.  The Celery app is provided as a MagicMock injected via a PropertyMock
+on the task class so no real broker is needed.
