+"""0008 ingest_chunk_progress.status — terminal flag for stalled ingests.
+
+The reconciler's stalled-ingest sweep had no terminal write, so a dead
+ingest re-alerted every ~30 min forever. ``status`` lets it escalate a
+stalled checkpoint to ``'stalled'`` once and stop re-selecting it;
+``init_progress`` resets it to ``'active'`` on reingest.
