 分包步骤：先识别每个信息单元的主体、行为或主张、对象、发生时间、地区、统计期和内容类型，再对照给定候选。同一具体事实的转载、标题改写、多语言报道归入同一包；相同主体、主题或相似措辞不是同一事实的充分条件。新进展、不同统计期、不同政策动作另建包；评论与它讨论的事实报道分包。宁可保留事实边界，不将多个独立事件合成一个大主题。
@@ -25,7 +25,7 @@ event_timeline任务整理已核验包的过程：区分发生时间和报道时
 claims逐项输出statement、verdict、evidence_refs；verdict只用supported/partial/conflicting/insufficient/refuted。非insufficient结论必须有实际原文证据；相互矛盾的来源都应保留。verification按official/reported/unverified/refuted/insufficient说明信息状态，confidence用low/medium/high独立表示把握，不能用高重要性代替高可信度。证据不足无法判断方向时direction必须unknown，不用neutral掩饰未知；整体verification=insufficient时direction只能unknown。
 重要性importance_stars：1背景信息，2局部进展，3重要变化，4广泛影响，5重大系统性变化。评估阅读必要性、影响范围和新颖性，不依赖是否存在风险；科技突破、政策改善等利好也可高重要性。
 风险risk_stars：0无明显风险，1轻微，2有限，3显著，4严重，5极端或系统性风险（5X）。结合潜在损害、传播范围、持续性、可逆性评估；可信度另行标注。严重但未证实的安全传闻可以提示高风险，同时明确条件和低可信度，不能写成已发生。政治或社会事件不因不属于财经而漏评，也不因政治标题自动升为最高风险。没有行情证据不得编造涨跌幅。例如交易所被盗报道与市场下跌同时出现，须分别核实，不能仅凭同时发生认定因果。
-输出：summary为简明事件总结，facts区分事实与未核实主张，timeline保留来源时间与统计期；timeline_points逐点输出occurred_at(带时区或null)、time_precision(minute/day/month/unknown)、time_text(来源时间原文)、reported_at、description、verification和evidence_refs；未知时间不填造，不能将报道时间当发生时间，asset_impacts说明有依据的市场或社会影响及传导条件；无依据时明确无法判断。reasoning解释评级依据，opinions提出有条件的相关意见，counter_evidence保留反证和替代解释，uncertainty列出缺口，watchpoints给出可观察的后续信号。related_packages只引用实际查询过的其他包，使用related/followup/supports/contradicts/corrects并解释关系，关系不是因果证明，不引用自身。只有文章完全不包含当前包相关事实时才列入excluded_article_ids，不能因一文多事件排除有效来源；混包应明确报出，不生成混合结论。
