feat(news): index news packages and research persistent events

Extract reusable literal keywords once per source revision, assign complete news packages to long-lived events, and research all event members with immutable evidence and references.

Add additive research storage, vocabulary snapshots, the two-stage workspace, isolated acceptance coverage, and a paused rollout with an initial fixed 50-news production trial.

+一个包可以关联多个事件：综述涉及多件独立事件时，各填一个归属，以对应连续原文quote说明相关部分，不能因主题相同而合并独立事件。
+事件以主体、具体事项和发生批次或统计期为边界；归属reason明确说明同一事实主线及原文依据。直接后果、回应、调查、更正、赔付属于原事件；独立决策或行动、新事故、新统计期另建事件，不能因为相关而强行合并。原文明示由某次数据发布引起的直接市场反应归入该次发布；独立政策决策另建。例：瑞士10月CPI环比、同比和受该次CPI影响的欧元兑瑞郎反应同属发布事件；瑞士11月CPI另建。币安同一次被盗及数月后追偿同属一事，第二次被盗另建。单次事故的资金追踪、冻结或追回即使由另一国家机关执行，也属于原事故直接处置，不能仅因执行主体或国家不同另建；只有原文明示独立案件范围（例如同一平台处理多起无关犯罪的执法）才另建并引用事故。关联不明时独立建事件并在reason说明缺口，不编造因果。
+优先检查给定的长期事件候选；同一次事故、回应、调查、损失修订和处置可属于同一事件，即使横跨数月。仅主体相同不是同一事件。
+候选reporting_range是报道时间范围，evidence包含首条与近期成员原文线索，不等于事件发生时间；结合quote中的日期、统计期及具体事项区分每日数据、不同次事故等独立事件，不能仅因名称或TAG相同而归并，也不能仅因报道间隔长而拆开同一事件。
+每个target填写event_id或new_key且恰好一个非空、title、reason、quote和change_kind、urgent。已有事件沿用ID；无合适候选则创建可独立识别的新事件名称，不编写事件总结。至少归属一个事件，单包事件也成立。
+change_kind=repost仅用于没有新事实或独立佐证的重复报道；new_fact为新进展，new_evidence为独立证据，correction为纠正/反证。转载各自保留包，只是不要求事件重研。urgent只用于重大紧急新进展。不要编造候选ID。通过submit提交完整targets。"""

+所有evidence_refs的article_id使用输入文章id或工具返回引用ID。补充原文read_news/read_package返回的article_id可能为负数，必须使用该article_id，绝不能使用news_id、包id或其他事件AI总结里历史引用的正数ID；例如工具返回news_id=1004、article_id=-1，本轮该补充原文所有引用必须填-1。其他事件总结中的引用ID不属于本轮证据命名空间。

+网页正文可能在机构名、主体、金额单位或专有名词前后保留换行及括号；quote必须复制完整原句并原样保留这些字符，在JSON字符串中用转义换行表示。不能为避开换行把主语、责任主体或名称截掉，也不能将括号里的名称与前后文改写拼接。关于攻击归因或活动名称的主张，引用必须包含明确归因的完整句及所称名称；独立标题与没有名称的半句不能共同证明该名称。与本事件无关的其他官方链接无需读取或产生额外主张。
+独立执法事件原文明示涉及其他已发生事故（例如洗白Bybit被盗资金）时，也应检索并读取该事故成功版本，以background或support引用；不能仅因本案是独立事件省略关联引用。原文明示其他独立事件作为本次决策依据或研究对象时，检索并读取其成功版本，按实际用途添加references；无成功版本则说明缺口，不伪造引用。

 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。
-输出：reason说明本条的分包依据；packages中已有包只填写候选package_id，新包只填写稳定的group_key，两者恰好一个有效。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。
+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。'''),

-核验流程：围绕影响结论的关键主张与缺口，有针对性地查询站内新闻、其他包、经济日历及外部来源。可读取当前包已有总结作为版本比较线索，说明新增事实、更正或撤回，但旧AI结论不能自证。每次最多4次本地搜索、8次本地读取、2次外部搜索、4次网页读取，最多8轮工具后提交；优先核验能改变判断的主张，不做无目标遍历。预算或上下文不足时明确尚未核实什么，不声称完成全面核验。
-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。

-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用planned_at/planned_precision保存计划日期，用period_text保存统计期，不能把计划当已发生；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；未知时间必须occurred_at=null且time_precision=unknown；已知时间带时区且精度不能为unknown。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。

+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。'''),
