The sync routine deletes all AilssNote/AilssTarget nodes before any inserts, and each step runs outside a single transaction. If a later batch write fails (e.g., transient network/auth error or memory limit), the mirror is left empty or partially rebuilt. In non-strict mode the indexer logs and continues, so MCP will treat Neo4j as available but serve incomplete data. Consider staging writes in a transaction or swapping in temp labels to preserve the previous mirror on failure.
