The output is a single tracker ("the **kept** issue") that carries every reporter's credit, every mailing-list thread, and every independent report's body, with the other tracker ("the **dropped** issue") closed and labelled `duplicate`. This is **one of the few places in the security workflow** where a piece of reporter-supplied content (the dropped issue's body) moves from one tracker to another. Since the target tracker is private to `<tracker>`, no confidentiality boundary is crossed, but the skill must still preserve every reporter's
