510 stories had stale 1_backlog stages in the CRDT because they were imported during the filesystem→CRDT migration and then moved forward via filesystem-only moves that never wrote CRDT ops. This made done stories appear as ghost entries in the backlog. On startup, reads the authoritative stage from pipeline_items and corrects any CRDT entries that disagree.
