Claude proposes duplicates to merge, related cards to combine, and stale cards to close. The surviving card absorbs the notes, dates & links from anything it closes — you see the full merged result here before you tap. Propose-only; nothing moves on its own.
/rethink over your live queue · card detail from QUEUE_JSON.PROOF/ACTION before they're closed. All through the engine — logged to Action_Events, never a raw cell edit.
