Expose persistent collection gaps and public Congress links

Retain bill and attachment failure reasons and derive retry counts from saved cursors. Show gap details and retry exhaustion in the collection console while preserving historical records and retry limits.

Convert Congress API bill links to public pages and cover diagnostics, mixed dated versions, persistent counts and legacy records with regression tests.

+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。"""

+梳理事件是什么、主体、发展状态、关键因素、影响渠道。对照previous重点研究新增进展和冲突，沿用仍成立的判断；previous不能覆盖本轮原始证据，也不能让旧版本混入的独立事项继续留在本事件。
+先核对每包的scope_quote、reason和keyword_canonicals确定当前事项；keywords仅保留该次归属所选TAG及其原文别名。other_scopes列出同包已另行归属的独立事项，不能因主体、地点、公告或文章相同而重新混入。scope_selection=legacy_unscoped、keyword_canonicals=null表示历史没有可确认的精确TAG选择，此时keywords仅是历史整包索引，不证明其全部属于本事件，仍依scope_quote/reason和原文判断边界。TAG用于定位，不能替代原文事实，也不能遗漏同一事件在其他句子中的主体、因素及后续进展。
+必须阅读完整原文，不把归属引文当全文。title、summary、facts、claims、timeline及timeline_points均只写当前事项及其直接进展，评级和影响判断亦只针对当前事项。other_scopes中的独立行动不得列为本事件事实、主张或时间线节点；只有解释本事件确有必要时，才在reasoning明确标为“其他事件背景”，并按实际用途查询引用其成功版本。例如同一公告中的油轮触雷与另两艘船被拦截，分别归属后各自总结、核验和记时间线；不能把拦截也写进触雷事件。提交前逐字段检查，不能只检查标题。
+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。"""
