Usher Lantern Handoff Receipt / 引座灯笼交接回执
When a blackout displaces a row, the lantern that guided them becomes a receipt, not decoration. The storyline asks who carried it, who claims the safety credit, and which future reader is allowed to consume that safety proof.
Required state: displaced row, lantern source row, original usher or explicit absence, receiving handler, requested afteruse, claimant families, harmed audience or crew, proof bridge, and future route effect.
