Reuse Federal Register discovery checkpoints across rounds

Bound document retries across realtime and history lanes, preserve safe completed reads on failed rounds, and retain unresolved gaps. Honor the longest access-block cooldown and measure retries from the actual failure time.

Filter dated official listings at the collection boundary, handle empty Federal Register days, and distinguish active rounds from waiting or failed processes in the console. Add captured-response regressions and isolated checkpoint validation.

+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、keyword_canonicals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。title与quote只包含本事件事项，quote保留其主体、动作和对象；综述的其他事项不要混入。不能仅引用“下跌”“另有”等失去主体的片段；原文确实未具名时不补造。
+keyword_canonicals从输入keywords中逐字选择与本事件相关的canonical，至少一个且不重复，不创造或改写TAG。阅读完整原文选择主体及相关要素，包括归属quote之外同属本事件的姓名、英文名、因素和进展；程序保留所选TAG的全部原文别名。单条quote仅作归属证据，不是TAG覆盖范围；综述其他独立事项的TAG不选。
+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。"""

+summary为事件总结；facts为已知事实；reasoning为判断依据；opinions为相关意见；uncertainty写缺口和争议；counter_evidence写反证；watchpoints写后续验证点；asset_impacts写有证据的影响，不强造市场关联。
+importance_stars独立评估：1背景、2局部、3重要、4广泛、5系统性。risk_stars：0无具体负面迹象、1关注、2警惕、3重大损害、4严重广泛冲击、5系统性危机。证据不充分降低confidence，不机械提高风险。verification=insufficient时direction=unknown。
+claims聚焦原文明示的关键主张、实质冲突及会改变判断的误读；不凭空增加“已获官方认证”“已决定全国控制权”等主张再机械判为不足。报道某人作出预测与预测已经实现分开。先核对数字、单位、期间和口径，保留算术反证能力。summary概括结论，reasoning说明推理，uncertainty集中写缺口，counter_evidence写实质反证或说明未发现，不在各字段重复整段限制。official仅表示核心主张得到实际读取的官方正文支持，不因有一个官方链接就覆盖其他未核实主张。
+每次查询先明确要解决的关键缺口：是否会改变事件身份、核心事实、核验状态、评级或判断。普通行情可直接按reported提交，不强查原因或收盘状态；重大事故、矛盾数字和关键政策仍优先核验。优先具体原始发布而非宽泛首页，不为补齐字段外搜。同稿复述没有新增信息时停止沿线查询；服务不可用或403后，仅在有不同且具体有效线索时继续，否则提交并集中说明局限。搜索失败不是反证。可独立进行的查询合并在同轮调用，不为每项claims各查一轮，不减少必要取证。
+articles已有成员完整原文时直接复用正文和文章id，不再逐包调用read_package/read_news，也不把重复读取当独立核验；仅输入extractions而无全文时，可按需读取对应成员原文。工具返回already_provided即使用先前已提供正文及article_id，不重试同一成员，也不继续逐个读取其他已提供成员。先列出会改变判断的最少证据缺口，将无需依赖彼此结果的站内查询和已知URL读取合并同一轮；拿到线索后才执行依赖它的读取。每轮检查是否有新增有效证据；没有可解决关键缺口的新具体线索时立即submit，未解决项写uncertainty，不为凑核验轮次或空字段继续查询，不跳过重大事实所需的有效取证。
+claims逐项核验，只有可能改变结论的缺口才查询站内新闻包、事件或外部资料。不机械耗尽预算；同稿转载和多个事件引用同一原文不是独立确认。搜索失败说明局限。已知官方公开URL可直接read_web；URL和搜索摘要不是核验证据，只有实际读到的正文才能引用。恢复客户资产余额不等于追回被盗资金；金额估值、可追踪比例须保留各自时点与来源，不将变化机械当成矛盾。
+时间线timeline_points按实际发展组织，转载可共用一个节点，不强制每包一节点；成员包进展的节点填写package_ids及各包对应原文evidence_refs；packages.id是包ID，packages.news_id是文章ID，二者不能混用。仅由工具补充材料支撑的背景节点package_ids填空数组，不能冒用成员包ID。发生、计划、报道时间和统计期分开；未知为null/unknown。time_text逐字取自某条quote，不用报道时间替代发生时间。
+日和月精度的occurred_at/planned_at统一以UTC零点存储日期标记（日取当日、月取首日），它不是实际发生瞬间，不按事件所在国家猜时区；明确的当地日期保留其原日期，不先换算UTC日期。分钟精度仅在原文明确时区或可由具名交易场所明确确定时填写，否则保留time_text并填null/unknown。只有报道日期不能推定发生日期。季度及年度保留period_text，不伪造月或日精度。
+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。
+引用应选能完整支撑主张的最短连续原文，保留主体、动作、对象、日期与必要限定；不能用孤立机构名、日期或被截断的半句拼凑归因结论。找不到足够证据时降低核验结论，不补写来源。所有quote必须是对应标题、摘要或正文的连续逐字原文，不改写、不拼接、不跨文章。previous和其他事件AI总结仅为线索，不能自证。
+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。
+references仅引用本轮实际读取的其他事件成功version_id，role用background/support/subject，reason说明用途；不能引用自己。相关主张必须另有原始证据，避免循环自证。没有引用则空数组。
+完整填写schema字段，id原样返回；excluded_article_ids必须为空。不确定的事实明确限定，不编造时间、行情、因果或预测。通过submit提交。"""

+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。

+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。

This measure reflects the number of employees on ADP client payrolls (Payroll Employment) to provide a richer understanding of the labor market. ADP's pay measure uniquely captures the earnings of a cohort of almost 10 million employees over a 12-month period.</p>
+<p>"The labor market downshifted to a more modest pace of growth in the final month of 2024, with a slowdown in both hiring and pay gains," said <span class="xn-person">Nela Richardson</span>, chief economist, ADP.
