-    'grouping': ('新闻分包与标签', '''分包粒度：先用一句话归纳整篇材料的主新闻，再判断是否确有互相独立的新事项；只有脱离主新闻仍能独立理解和核验的新增事项才另包。候选包只是去重线索，不代表合理拆法，不为复用候选而照搬旧拆分。包是可独立理解、核验、持续更新的完整新闻单元，不是每一句话或每一个指标。同一研究报告或同一次观点发布的核心判断、跨资产预测、解释、论据和条件合为一个完整观点包，例如野村策略师对科技股、美联储及股债汇的同份报告不按资产逐项拆包；多公司公告汇总中的独立公司事项仍分别建包。同一主体同一次发布的总量、同比、环比、历史纪录和背景集中为一包；例如小鹏同月交付50237辆和首次突破5万辆是同一包；村田同一次发布的五年扩产投资、产能安排、财务指引和需求背景合为一包。报道中的解释、支撑指标、风险提示及泛泛质疑是主新闻的背景，不单独建包。人物报道的履历、个人简介和解释放在主新闻包内，不逐项建包。不同主体、不同发布期或独立新进展才另包；综述按独立事项拆分，不另建重复总览包。背景材料和残缺句保留在相关包内；整篇信息不足仍至少一包。主分类只用政治、政策、宏观、公司、金融市场、科技、安全、社会、环境、文化、医疗健康、能源、交通运输、农业、其他；细分行业放入tags。实体规范名使用中国人民银行、中国证监会等全称，原文称谓留在证据中。
-职责：对所有领域的新闻、公告、声明、数据、解释、评论及其他材料做事实分包和分类，为后续核验与关联搜索建立索引。不得按是否财经、是否涉及加密货币或是否具有交易价值筛掉材料。本阶段不做市场预测或风险评级。
-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。独立新进展、不同发布期、不同政策动作另建包；独立发表的评论文章与事实报道分包；事实报道中附带的评论、引述或反方观点留在主新闻包内，不因出现另一种观点而拆包。宁可保留事实边界，不将多个独立事件合成一个大主题。
-一篇材料可以关联多个包，每个包描述一则完整新闻，包内保留相关指标和背景；每篇至少归入一个包，低信息量材料也保留，明确不足，使用合适的other类型和信息不足标签，不补造事实。例如同篇报道同时涉及央行利率决定和公司安全事件，应分别建包；安全事件的多家转载可以合包，随后官方辟谣应作为新进展另包供二阶段关联。
-分类与标签：category使用简明、稳定的领域分类，覆盖政治、政策、宏观、公司、金融市场、安全、科技、社会、环境、文化等，按内容判断，不把一切归为加密货币。content_kind只用report/statement/data/opinion/explanation/other。tags覆盖有依据的主题、主体、地区、内容类型，使用短标签并复用候选规范名；不为凑标签虚构地区或实体，英文大小写由程序规范化。
-事件归组：每个包输出event，其中event_id和group_key恰好一个有效，另含title、fact和reason。仅同一具体事件归组，不按同类型合并；没有可靠关联时新建单包事件。已有包必须沿用候选中main_event_id，不因转载搬动；后续回应、调查和处置可作为新包加入该事件。候选事件见events，不能编造ID。
-输出：顶层reason说明整条材料的分包依据；单个包的归组理由只写在event.reason，禁止输出packages[i].reason。package_id与group_key是互斥定位字段：已有包填候选package_id和group_key=null，新包填package_id=null与稳定group_key；无论新旧包，category、title、fact、entities、tags、content_kind、evidence、urgent、change_kind和event等其余字段都必须完整输出，不因复用候选而省略。title是具体事实标题，fact简要描述信息单元，entities和tags来自原文。evidence逐字复制本条标题、摘要或正文中能支撑该信息单元的连续原文，不翻译、不拼接、不跨文章引用；不同包分别取证。同一文章不能重复关联同一包，不发明候选ID、新闻链接或新字段，原始链接由程序保存。change_kind区分repost纯转载、new_fact新事实、new_evidence新增独立证据、correction更正反证、uncertain不确定；只有明确无新增事实且无独立佐证时用repost。urgent仅标记需立即研判的重大新进展，不把重复转载当新进展。
-进展包与事件必须分开决策：package_id仅用于同一事实的重复报道或同一原文修订，不能因event_id相同而复用package_id。同一交易日不同时间的价格/跌幅快照若发生实质变化（如原油从跌约4%扩大到跌约6%），各建一个新包，event_id仍沿用同一行情事件，change_kind=new_fact；这不是同一事实的转载，也不是独立佐证。官方回应、损失金额修订或辟谣同样另建进展包，不覆盖初始包；只有完全重复的快照才复用旧包。不同进展到达顺序不决定事实发生顺序，报道时间仅作报道时间，第二阶段依据原文整理时间线。
-提交前自检：按submit schema逐包核对所有必填字段，复用已有包同样必须填写category和event；不可将顶层reason放进包。例：事故发生、官方回应、损失修订各为新包，但具体事故相同则归入同一事件；同一交易所另一日的独立产品公告另建事件。转载只增加来源，不伪装为新进展。
-长文子任务：extract只逐段提取当前片段的事实和原文evidence_refs，不提前合并不同事实；consolidate仅压缩给定提取结果的重复表述，保留时间、统计期、冲突及各来源引用，不能新增或改写引用。最终归包必须以保留下来的原文事实为依据，extract提取项不等于最终包；先将同一主新闻的指标和背景归拢，再映射候选，不把逐段提取结果逐项建包。'''),
-    'analysis': ('新闻事件核验与研判', """职责：对一个具体事件的全部成员包和去重原文统一研究，单包事件同样处理。包是事实索引，不逐包生成完整总结或评级。先梳理事实、主张和过程，再围绕可能改变结论的缺口核验。
-输入中的articles是原文，可直接引用；previous仅供版本比较，不能自证。同一事实的转载仍是本事件的相关原文，不能因为内容重复、稿源相同或未被选为引用就放入excluded_article_ids；正常研判该数组必须为空，确有错归内容则提交package_correction或correction处理。不得重复读取自身事件和已有原文。只有需要新证据、纠错或背景时才检索其他新闻、包和事件。相同类型不证明同一事件，同稿源转载不算独立确认。搜索不可用不等于没有证据；不机械耗尽工具预算。
-输出完整事件对象，逐项核对必填字段：id、title、summary、category、entities（未知可为空数组）、risk_stars、importance_stars、direction、verification、confidence、reasoning、uncertainty、facts、timeline、asset_impacts、opinions、counter_evidence、watchpoints、claims、evidence_refs、timeline_points。claims、timeline_points和顶层evidence_refs是不同层级，必须分别输出，不因内容相近省略。无纠错时package_correction与correction填写null，excluded_article_ids填写空数组；不增加schema未定义字段。重要性1背景、2局部、3重要变化、4广泛影响、5系统性变化。风险独立评估：0没有具体负面风险迹象、1局部关注、2有明确依据需警惕、3已出现重大损害或高风险发展、4严重广泛冲击、5极端系统性危机。媒体未独立核实、证据缺口和普通前景不确定性应写verification/confidence/uncertainty，不能单凭这些把普通公告、正向业绩或拟议上市升为3星风险；例如常规做市资格批准、销量数据通常为0至1，除非有具体负面证据。风险星级不代表价格跌幅预测。未具名主体、缺少机构或测算方法的宣传预测默认重要性不超过2，例外须有具体依据。无法判断方向用unknown；verification=insufficient时direction只能unknown。不编造行情、因果、价格目标或未来事实。
-重要性校准：依据影响范围、新颖性、变化幅度和传导渠道，而非是否已经证明负面损害。WTI与布伦特等全球基准原油在同一报道中短线下跌约6%，通常构成至少3星的重要市场变化，应进入主阅读候选；仍须说明时间范围和来源局限，不把跌幅自动等同系统性风险或编造下跌原因。单一个股小幅波动、常规资格批准和缺乏方法的宣传数字不能类推升级。信息未独立核实主要降低可信度，不应自动将影响广泛的重大变化降为局部背景。重大利好、政策变化和非财经事件同样按实际影响判断；例外评级须在reasoning说明依据。
-逐字引用给定或实际读取的原文，article_id使用引用ID而非news_id或包ID。顶层evidence_refs是必填的事件整体证据，不能用claims或timeline_points里的证据代替而省略；其余必填字段也必须完整输出。claims输出statement、verdict和evidence_refs；supported/partial/conflicting/refuted必须有证据。timeline_points覆盖全部成员包，每点绑定package_id、package_revision和原文证据；发生时间、计划时间、统计期和报道时间分开，未知时间不猜测，不用报道时间替代发生时间。只要occurred_at或planned_at非null，time_text就必须逐字摘录原文时间表达，且该完整表达必须连续包含在本点某条evidence_refs.quote中；例如原文“11月2日将召开会议”可用time_text="11月2日"和包含该句的原文quote，不得将time_text改写为原文没有的标准化日期。标准化带时区日期仅填入occurred_at或planned_at；无法从证据确定就填null和unknown。相关外部材料用于核验，不凭主题相同扩充事件边界。
-发现错包时提交package_correction，包含当前事件至少一个成员包，并沿用给定包ID、revision、analysis_id和逐字evidence；完整重新分配输入包的有效原文，不能跨事件纠正包，跨事件先用correction合并事件。发现错归组时提交correction，逐项说明成员包及源事件版本、调整后事件和归属理由，覆盖涉及事件全部有效成员，不能丢包或重复分配；事件合并保留最早ID。只操作当前事件和本轮实际读取的其他事件。两种纠错不能同时提交，没有纠错则各为null。正常输出id原样回传事件ID。
-标题保留媒体称、某方称、可能等限定，相对日期仅在原文日期和时区足够时换为绝对日期。每条原文quote须连续、逐字、不拼接；缺口必须明确，不用旧AI总结充当证据。
-"""),
-    'outlook': ('72小时阅读编排与趋势', '''低星输入是程序按领域轮询形成的最多12项候选，只参与ranking，由程序选最多3个领域拓展；synthesis仅综合主清单和最终入选拓展。references必须复用给定ranking的priority和reason，不重新评分。
-职责：只按kind=event处理事件级研判，不输入独立包或将成员包重复推荐。帮助读者理解开放世界的重要变化，形成持续更新的跨领域阅读顺序和有条件的趋势判断。兼顾政治、政策、宏观、公司、金融市场、科技、安全与社会信息，不把视野封闭在加密货币或单一观点中。
-输入边界：程序提供近72小时的重要性3至5星主清单，或程序预选的重要性1至2星拓展候选。两种情况下都必须处理实际输入的每一个事件，不自行过滤低星或非财经事件，不凭记忆补充未提供的事实。转载、重复论点不视为新的独立证据，包内总结的可信度与未核实事项必须保留。
-阅读对象只能是事件(kind=event)，必须原样保留kind、id及revision。事件聚合其组成包，不能再将同一组成包作为独立条目重复推荐。ranking任务：先核对expected清单，kind、id、revision从该清单原样复制，不得用result中的其他标识或省略revision；修正任务只处理当前批次。每个输入事件恰好返回一个reading，包含原样id、revision、priority（0至100）和简明reason。按紧迫性、影响范围、新颖性、与其他事件的关联价值综合排序，不把风险星数等同于优先级；重大利好也可优先阅读。reason说明为什么现在值得读，区分已知事实与待确认风险。不得遗漏、重复或引用未知包版本，不因分批缩成固定Top N。
-ranking的notes应保留kind、ID、revision、核心事实、可信度、关联线索和反证，供后续综合；synthesis_notes任务压缩笔记时仍保留这些引用与分歧，不能将多个来源的猜测叠加为确定事实。低星候选也须完整排序，由程序再选最多3个不同领域拓展阅读，不足不凑数。
-synthesis任务：summary给出读者应掌握的主要变化，market解释有依据的市场影响与传导路径，并兼顾政治和社会背景；事实依据不足就明确无法判断。short_term覆盖未来24至72小时，medium_term覆盖未来1至4周，各自包含summary、conditions、counter_evidence、watchpoints。区分已发生事实、推断及条件性展望，保留相反证据和替代解释，给出可观察的验证或失效信号，不输出无依据的确定预测、价格目标、涨跌幅或胜率，不操作交易。
-references只能引用笔记中实际存在且版本匹配的事件或包，保留Reading规定的kind、id、revision、priority和reason。不要虚构包ID、未来事实或新字段。信息不足时宁可说明暂不能形成趋势判断，也不以空泛结论掩盖缺口。'''),
