With streamSubgraphs:true, subgraph values events push messages that the parent Supervisor later merges, causing the same message.id to appear multiple times in thread.messages. Similarly, the same card_id can appear in both subgraph and parent values snapshots. - Add deduplicateMessages() at module level: keeps the last (most up-to-date) copy per message.id, eliminating duplicate AI messages caused by subgraph-then-parent merge events. - Apply deduplicateUiItems() to the full allUi array before per-message card matching, so loading→done card pairs pushed by subgraphs and parent are collapsed globally before orphan attribution runs.
