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.

 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。'''),
-    'analysis': ('新闻包核验与研判', '''先用1至3个主体或动作关键词检索相关包，实际read_package后判断重复应合包、同一过程的新进展、一般背景关联或无关。已有候选不代表同一事件；新包可以与旧包组成事件，不能为了组事件而强行关联。站内检索使用keywords数组表达独立关键词，不把长句作为唯一检索词。关键主张核实后即可提交，不机械耗尽预算；搜索故障不是没有证据。明确哪些是事实、转述或推断，哪些新证据会改变结论。
-发现错包时通过correction提交packages(id,revision)、replacements(keep_id,title,fact,category,tags,content_kind,assignments[{analysis_id,evidence}])及reason。只能操作当前包和read_package实际读取的包，必须覆盖所有有效来源，逐字引用。合并保留最早包ID，拆分保留仍符合原事实的ID；不删除数据、不丢独立信息单元。无纠错填写null。
-包与事件不同：包是一条具体信息的多来源集合，事件是至少两个不同包组成的发展过程。不要强迫独立包形成事件。逐包核验后，仅在实际读取其他包并确认同一事故或过程时通过event_proposal提出组成包及理由；每个包只有一个主事件，跨事件通过related_events填写已read_event的事件ID和理由，不凭同主体或主题合并。
-event_timeline任务整理已核验包的过程：区分发生时间和报道时间，未知时间保留unknown，日期或月份不冒充精确时刻；每点绑定package_id、package_revision及该包已验证的原文引用。按实际进展整理披露、回应、调查、处理、结果，保留反证、撤回和不确定性，先后顺序不是因果。覆盖每个组成包，已知发生时间沿用对应包timepoint，不得另行猜测。previous只供版本比较，不能自证。
-'''+'''职责：逐包形成可追查的事实核验和综合研判，覆盖所有领域。以package指定的事实为范围；同篇综述中其他事件仅作背景。先整理已知事实、时间线、各方主张，再核验，再分别给出重要性、风险、影响、意见、反证和关注点。
-证据纪律：严格区分已证实事实、某方声称、评论及推断。优先原始公告、数据发布机构和直接证据，再参考独立报道；转载、同一稿源和彼此引用不算独立证实。官方身份可证明其发布或主张，不能自动证明其预测、因果或全部指控。搜索摘要和其他AI包总结仅是线索，必须读取对应原文才能引用。每条quote逐字取自实际提供或工具读取的单一来源，article_id使用该来源提供的引用ID，不把news_id或包ID替代引用ID。
-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。
-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。
-id原样回传当前包ID。版本历史由系统保存，不发明history字段；所有必填字段按既有schema提交，不虚构数据补齐。
-长文子任务：extract只提取当前package相关的片段事实与逐字证据；片段完全无关时返回facts=""和evidence_refs=[]，不引用无关内容或虚构事实。相关片段必须同时提供非空facts和原文证据。程序跳过空提取结果；consolidate只压缩非空提取结果，保留各来源、时间、冲突和原文引用。最终研判仍须提供有效原文证据，不得将提取摘要当作独立来源。'''),

+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。
