      "content": "请基于场景、时间线、实体上下文，以及程序生成的影视化改编候选，输出一个更适合后续 screenplay 阶段消费的 scene-level adaptation brief。输出必须是严格 JSON，键为：scene_id, decision, presentation_mode, story_function, adaptation_focus, must_keep, may_compress, visual_focus, audio_focus, continuity_requirements, script_objective, conflict, turning_point, reason。scene_id 必须与输入一致；不得新增其他顶层键。必须保留 chronology 所表达的时间模式与顺序差，不得自行重排或删改时间结构。must_keep / may_compress / visual_focus / audio_focus / continuity_requirements 都应是短列表。只返回单个 JSON 对象，不要 markdown，不要代码块。如果无法判断，至少返回原候选中的 scene_id、decision 和
