+/// Pre-1036 code left stale MergeJob entries after a story recovered from a
+/// merge failure and transitioned to Done.  Those entries caused the gateway
+/// UI to mislabel recovered stories as "FAILED" because `load_pipeline_state`
+/// unconditionally read the MergeJob error field for every story.  This
+/// migration removes the orphaned entries so the state is clean on the next
+/// server start.
+///
+/// Running this migration repeatedly is safe — tombstoned entries are filtered
+/// out by the read path, so subsequent calls are no-ops.
