Count attachment transport failures and preserve updated article bodies

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.

+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。

+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。"""

+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。
-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。'''),

-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。
+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。
-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。
+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。
-'''+'''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。
+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。
-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。
+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。

-## Three-stage news research
+## Two-stage news research
 
-The `news-risk` service runs three model stages with separate durable queues for grouping, package review, event timelines, reading and explicit reprocessing. Original news and revisions remain in their existing tables; AI packages, package versions, memberships and research evidence are stored separately.
+A news item has one stable package, identified by `news_items.id`. Reposts remain separate packages; a digest is never split into new packages. All original news, revisions and legacy AI tables are retained.
 
-1. **Grouping:** the selected Luna model processes every domain and content type, including political news, statements, data, explanations and opinions. Reposts of the same concrete fact share a package with original links and normalized tags. New developments and opinions form separate packages; topic similarity alone is insufficient. One article can contribute to multiple packages.
+1. **Keyword indexing and event assignment:** read the complete news once to persist canonical TAGs, literal aliases and original supporting quotes. This stage generates no summaries or ratings. Assignment is a separate persisted subtask, so a classification retry reuses the keyword index. Packages and events have many-to-many membership; a digest can support several distinct events, and a single package may start an event. Event candidates cover all time, bounded to sixty lexical matches. Shared names or sectors alone do not establish a common occurrence. Source-content changes explicitly invalidate the index; oversized single-news input fails without truncation.
-2. **Package review:** a separately selected model receives the package fact, title, category, tags and content type alongside its original articles, so separate facts within one roundup retain distinct review scopes. It records facts, timeline, claims, verification verdicts, counter-evidence, related packages, opinions and watchpoints. Reading importance (1–5) is independent of risk severity (0–5), so major positive developments can enter the important reading list. Each attempt permits four local searches, eight local reads, two external searches and four external reads, across at most eight tool rounds followed by submission. Context planning reserves the research tool definitions before extracting or compacting long articles. News/package/calendar search and SearXNG are read-only. Search snippets and other AI summaries are leads, not independent verification. Quotes must occur in a source actually supplied or read; insufficient evidence must remain explicit. Tool responses, failed attempts and previously successful versions are retained. A manual retry can reuse saved successful tool responses; old failures cannot requeue a revision that already succeeded.
+2. **Event research:** read all current member packages and originals together, producing one event summary, claims, importance (1–5), independent risk (0–5), verification, factors, uncertainty, opinions, impacts, counter-evidence, watchpoints and timeline. Every successful result and failed attempt retains input, output, rules, usage and tool evidence. Long event inputs use evidence-preserving extraction/compaction across all originals or fail explicitly. Timeline nodes identify the corresponding member packages and their original news IDs; background nodes supported only by supplementary material have an empty package list. Literal quotes and source identities are validated before publication.
-3. **Reading and trends:** the independently selected advanced model ranks every successful event or independent package of importance 3–5 within the last 72 hours. Large inputs are processed in batches; truncated ranking outputs split into smaller batches, while a truncated single-package output fails explicitly. The complete reading list is retained and paginated, with strict package/version coverage checks. Up to three lower-importance packages from different domains provide expansion reading. Synthesis distinguishes facts from inference and gives market implications, 24–72-hour and 1–4-week trends, conditions, counter-evidence and watchpoints. Ordinary changes aggregate for 15 minutes; importance-5 developments can trigger earlier, with at least 60 seconds between starts. Citation-only changes do not repeat advanced-model calls; changed facts, ratings or verification verdicts still trigger updates. Reposts and analysis execution alone do not advance package source-progress timestamps. Window expiry also triggers an update. Failed refreshes retain the previous successful briefing.
 
-An event is optional and requires at least two distinct packages describing the same developing incident or process. A standalone package remains readable and can join an event later. Review must actually read the other packages before proposing membership. Each package has at most one main event; cross-event links remain separate. Event timelines preserve known, partial and unknown occurrence times, reporting times, verification status, original quotes and exact package versions. Unknown occurrence times are never replaced by publication times. A later event refresh cannot publish over changed member versions. Successful events aggregate their represented packages into one reading entry; typed `(kind, id, revision)` references distinguish events from packages.
+An event has its own continuing timeline. Research may refer to another event's successful immutable version as background, supporting material or subject. A changed referenced event is marked for the reader and does not automatically start another paid call. AI summaries are clues, never primary evidence. Tools allow four local searches, eight local reads, two external searches and four external reads per attempt; supplied articles and cached reads are reused. Tool failures remain visible as research limitations.
 
-Package review can request atomic split/merge corrections. Corrections lock and verify input revisions, require all current source assignments and literal evidence, retain old IDs/history, and preserve the earliest ID on merges. Repeating a correction with the same source hashes and Skill rules is rejected to prevent loops. Corrections are versioned separately; superseded package URLs link to replacements. A pure repost only adds a source; new facts, independent evidence and corrections request another review. Original news rows are never rewritten by AI.
+Research receives each member's selected `keyword_canonicals` and complete selected keyword records from its latest successful assignment snapshot, together with `scope_quote`, `reason` and `other_scopes` for independent matters in the same news. New assignments atomically retain resolved targets in `Attempt.rules.membership_targets`. Older assignments reuse their exact output selection when the owning target is unambiguous; otherwise `scope_selection=legacy_unscoped` and `keyword_canonicals=null` explicitly identify a historical full index. Missing successful input snapshots or mismatched original revisions fail durably before model I/O. The full original remains available; TAGs locate scope and do not replace evidence. Long-input extraction also receives these boundaries. The research Skill requires summaries, facts, claims and timelines to stay within the assigned matter, including when an earlier result drifted. Independent matters may appear only as necessary, explicitly identified background in reasoning with the appropriate event reference. These instructions require real-model semantic acceptance; structural tests alone cannot prove compliance.
 
-The homepage offers a publication-range reprocessing preview followed by explicit cost confirmation. Starting captures the latest source hashes, three model/effort configurations and published Skill contents; it does not reconstruct a historical information state. Jobs yield to pending realtime work, persist position and failure reasons, and resume after restart. Cancellation stops subsequent articles; an in-flight call and already queued package/event reviews may finish. Pause stops new work. Completion waits for package/event review and a reading snapshot; failures retain prior successful outputs. Failures identify their stage and object. Retrying grouping failures reruns only those news items; package review, event timeline and reading failures resume their own stages without repeating successful grouping. Retries can incur additional model costs. Pausing before a grouping call leaves the job checkpoint unchanged, even when an older successful analysis exists. Source revisions invalidate stale job items; select a new range to include the new revision. Shared packages/events may update even when some of their articles fall outside the selected range.
+The research Skill reuses complete originals already supplied in `articles`, requests original reads only when needed after extraction, bundles independent evidence queries and stops when no concrete lead can resolve a consequential gap. Repeated member reads return `already_provided` with a reuse instruction and are retained in tool audit records without consuming another read budget or duplicating the full text. The tool-round ceiling and evidence requirements remain unchanged. Updating defaults does not modify already published production Skills; publication and deployment require task authorization.
 
-The first successful enable operation records a permanent start timestamp. Only source publications or source updates after that timestamp enter the pipeline; ingestion of older history does not trigger analysis. Pause/resume retains the timestamp. Historical records remain available to research tools. No trading actions are triggered.
+Assignments select nonempty, unique `keyword_canonicals` verbatim from the input index for each target. Selection covers the relevant subject and factors throughout the original, including names outside the scope quote; unrelated digest matters are excluded. Unknown or rewritten canonical names fail validation. All aliases of selected records remain searchable. Successful assignment records store each resolved event's TAG contribution in `Attempt.rules.membership_tags` in the same transaction as memberships. Rebuilds union the latest successful assignment snapshots of current members; reindexing, pending/failed assignments and removed memberships cannot introduce new TAGs into old events. Original package keywords remain intact. Legacy assignments retain their complete historical input index; missing snapshots fail explicitly rather than reading a newer index. Deployment does not rewrite historical records or clean legacy digest noise; historical cleanup requires a separately authorized operation. Package search also matches whole ASCII name/model tokens of at least three characters inside current canonical names and aliases (`MI455X` matches `MI455X GPU`, but not `MI455X2`); stale package keywords remain excluded.
 
-During package review, long-article slices with no facts relevant to the package return empty facts and evidence together and are omitted from compaction. Relevant slices must retain literal source quotes; if every slice is irrelevant, review fails explicitly. Grouping extraction, compaction and final package summaries still require nonempty evidence.
+New event timeline day/month values are UTC-midnight calendar markers (first day for month precision), retaining the stated calendar date rather than converting a local midnight to a different UTC day. They do not denote precise instants. Minute precision retains its actual timezone; unknown dates stay null. Historical versions are not reparsed or rewritten. Research Skills require explicit timezone evidence for minute precision, and keep quarters/years as period text. Updated default templates must be reviewed and published as new Skill versions to change bound model instructions; changing source templates alone does not update published production Skills. Existing reviewed vocabulary remains the authority for name equivalence; no vocabulary is silently seeded.
 
-Create or update the three default news Skill drafts in homepage settings, review and publish them in the Skills page's News tab, then bind the grouping, package-analysis and reading Skills. Updating appends a new draft only when the latest content differs; it preserves node IDs, previous versions and published versions. Templates never publish themselves. `POST /api/risk/skill-templates` without a body, or with `refresh_existing=false`, only creates missing templates; the homepage explicitly sends `refresh_existing=true` to prepare updated drafts. News-scoped Skills never enter Chat/trading prompts. Publishing a Skill does not enqueue a historical reanalysis.
+Long-input compaction stops when the final research Skill, payload, tools and result schema fit the configured context budget. Extraction and consolidation keep their event-boundary instructions and check their own call budgets; the final fit check does not count member metadata a second time in those instructions.
 
-All three stages independently select a model and reasoning effort (`low`, `medium`, `high`, `xhigh`, `max`). Model selections support provider model lists and manual IDs. Clearing a stage's effort inherits its provider setting; if both are unset, no effort parameter is sent. Overrides do not change the shared provider. Each attempt retains the selected override, effective effort, rules and model identity; changing either the override or effective settings changes its configuration fingerprint. Test-and-enable makes real validation calls and reports unsupported settings without silently lowering effort; saving paused settings makes no model calls.
+Ordinary new facts, independent evidence and corrections aggregate for five minutes, with a fifteen-minute hard deadline. Urgent developments are immediately eligible. Pure reposts retain their own packages and citations without requesting a new successful event review. Indexing, assignment and research share the configured concurrency pool (1–16, default 3). Pausing stops new admissions; in-flight work drains. Interrupted tasks recover from PostgreSQL. Third-stage reading/trends, legacy queue/backfill jobs and old three-model configuration are not exposed or scheduled by this workspace.
 
-The additive `c3d5e7f90123` migration follows `b2c4d6e8f012` and adds three nullable stage-effort columns. Existing settings inherit provider effort. Apply it only with separate migration authorization through the normal deployment lock; it does not update live Skill contents, publish drafts, enable AI or reprocess history.
+The homepage provides event and package searches, pagination, membership details, timelines, evidence and version history. `GET /api/risk/settings` and `PUT /api/risk/settings` manage independent `index` and `research` model/effort/Skill bindings and concurrency; saving pauses admission. Clearing effort inherits provider settings. `POST /api/risk/enable` validates the two models with synthetic material, including separate index/assignment contracts. `POST /api/risk/packages` enrolls up to 500 explicit news IDs; while enabled the worker additionally admits news published since November 1, 2026, 00:00 Asia/Shanghai. Failed assignment retries reuse indexing; event retries never repeat indexing. Earlier source revisions are not shown with current revision annotations.
 
-The subsequent `d4e6f8012345` migration adds events, membership and cross-event links, grouping versions, correction records, reprocessing jobs and active article assignments. It seeds grouping history from existing analyses and pauses AI while leaving raw news and prior successful summaries intact. Both pending migrations require separate authorization under the deployment lock. Update and review the default Skill drafts before enabling the new output contracts; no historical job starts automatically. CI exercises migration and pipeline behavior using synthetic models and a disposable database, including cancelled/failed reprocessing, reposts and correction history.
+Create the two default Skill drafts in homepage settings, review and publish them in Skills, then bind them before enabling. Template generation never publishes or changes existing Chat/trading Skills. The additive `a71234567890` migration follows `f60123456789` and creates seven `news_research_*` tables; `b81234567890` adds the eighth table for immutable vocabulary snapshots. There is no conversion, truncation or deletion of original/legacy tables. Production schema execution, code deployment, commits and pushes require the corresponding task authorization; preparing a migration alone does not grant it.
+
+### First rollout of two-stage research
+
+The first rollout deploys the new workspace and binds the two published Skills while automatic news AI remains paused. The user requested a first production trial of exactly 50 frozen news items after deployment. Run only their indexing, assignment and resulting event research through the same runtime services, then leave automatic admission paused. Fifty news items require more than fifty model requests because assignment and event research are separate tasks, with bounded tool rounds and retries.
+
+Do not use the normal enable endpoint for this trial: it makes real synthetic model calls and admits news published since November 1, 2026, 00:00 Asia/Shanghai. A read-only check on November 4 found 3,388 eligible news items; this count will grow. Explicitly enrolling 50 IDs does not limit automatic admission after enabling. The acceptance allowance of 180 requests belongs to the earlier isolated acceptance runner and does not impose a production spending limit.
+
+The following steps are prepared operator instructions, not an instruction to run production changes without authorization:
+
+1. Review the complete working tree, including new files, and obtain task authorization for commit/push, the independent schema migration, deployment, and publication/binding of the two news Skills. A `dev` push publishes accepted images and automatically attempts deployment. Review the proposed scope before pushing; GitHub receives a public mirror. Keep all original news and legacy AI data.
+2. After the authorized commit/push, wait for the isolated check/build job and download its `build-receipt` artifact. Record the full commit, version and accepted image identities. The first automatic deploy is expected to stop at `Database migration requires separate authorization` while the database is at `f60123456789`; this check runs before stopping or replacing services. Do not disable the guard or bypass the deployment lock. If a different failure occurs, diagnose it first.
+3. Under `/docker/gitea/dev/AlphaPulse/.deploy.lock`, confirm no pending deployment, the approved commit is still current `dev`, legacy news AI is paused, the database is at `f60123456789`, and the candidate has the single head `b81234567890`. Validate both image identities using `scripts/deploy.py`'s `validate_images` and the downloaded receipt. Preserve the current deployment receipt, Compose and image selection. Create a private full database backup with the owning PostgreSQL container, record its checksum, and verify restoration in a separate empty database before migrating. Preserve the existing encryption key through its private configuration mechanism; never put it in reports or Git. A file existing or `pg_restore --list` succeeding alone does not establish recoverability.
+4. Still holding the same lock, use the verified candidate backend image with the existing instance `.env` and `dev_default` network to run `alembic upgrade b81234567890`. Only these two reviewed migrations may run. Check the resulting revision and eight new tables; verify original-news samples and legacy settings remain intact. The migration updates `alembic_version` as well as creating the new tables. If it fails, inspect the revision and tables before retrying; do not stamp a revision or drop tables to bypass a failure.
+5. Release the migration lock, then run the existing update command with that same accepted receipt:
+
+   ```sh
+   python3 scripts/deploy.py update --build /absolute/path/to/accepted/build.json
+   ```
+
+   The updater takes the lock itself and restarts the existing nine services using their existing configuration. Verify the served frontend/API commit, all service states, restart counts and search health. A newer `dev` commit causes the update to skip; obtain its accepted receipt and reassess migrations before continuing.
+6. In homepage settings, create the two default drafts through `POST /api/risk/skill-templates`. Review and publish **新闻关键词索引与事件归属** and **新闻事件整体研究** in Skills. Record their returned node IDs, published version IDs and content hashes, and verify their scope is `news` and they are enabled. The first content must equal `INDEX_SKILL + "\n" + ASSIGN_SKILL`; the second must equal `RESEARCH_SKILL` in the deployed candidate. Do not copy the sample-specific official-URL hints from isolated acceptance Skills into these production defaults. Preserve the legacy Skills and all Chat/trading bindings.
+7. Bind the returned Skill IDs to `index` and `research` with the reviewed provider/model/effort values and concurrency 3. Save settings, then read them back and confirm `enabled=false`. Published content is used together with the runtime base instructions; production has no fallback to an unbound default template. Configuration/publication does not call the models. Do not click test-and-enable, call `/api/risk/enable`, or import isolated acceptance outputs during this rollout.
+8. Verify homepage event/package lists, news details, vocabulary reads and authentication. Empty new event/package lists are expected before the fixed trial; originals and legacy history remain stored. Record the migration, served commit, Skill versions/bindings and paused state in the private rollout receipt.
+9. For the fixed trial, freeze exactly 50 distinct original news IDs and their content hashes before processing. In the absence of another selection, use the latest 50 and order them by publication time and ID for assignment. Keep the instance deployment lock throughout execution, stop only the existing `news-risk` service through the deployment controller's Compose command, and acquire the worker's PostgreSQL advisory lock `(20261030, 1)` before dispatch. Keep the research-settings row locked and `enabled=false`, and invalidate concurrent enable validation by advancing its control revision. Reject an existing research package outside the frozen selection; do not clear it. Validate the published model/Skill bindings without calling the normal enable endpoint. Index with concurrency 3, assign chronologically and serially, then research the resulting events with concurrency 3; each event reads all its member packages. Reuse completed stages instead of repeating successful TAG extraction. Abort if a frozen original changes. Preserve JSON checkpoints, attempts, versions, evidence, usage and failures; automated completion is not semantic quality approval. In a `finally` block, retain the paused setting, release the advisory lock and restore the previously running news worker under the deployment lock. Check the stored package IDs equal the frozen 50 and the automatic setting is still paused, then review TAGs, memberships, event conclusions, evidence and model usage. General production enablement remains a separate decision; neither this bounded trial nor historical samples prove long-running production quality.
+
+For a failure after replacement starts, `scripts/deploy.py` attempts restoration of the previous images/configuration. Use `python3 scripts/deploy.py recover` only when a pending deployment remains; use `python3 scripts/deploy.py rollback` for an explicitly authorized rollback after a successful deployment. Image rollback retains the eight new tables and their data and does not downgrade or stamp Alembic. Before rolling back an enabled system, pause news AI and check in-flight work; pause stops admission rather than cancelling requests already sent. Keep legacy news AI disabled so the old worker does not resume the three-stage flow. If new Skills have already been published, retain their versions for a later forward deployment. Do not restore the database backup over ongoing news/trading writes as a routine image rollback. The older image's Alembic CLI cannot resolve the new revision; run any subsequent schema inspection or migration using the candidate that owns it.
+
+Uncommitted preflight images are local test artifacts, not deployable CI receipts. Build them under distinct local tags and run isolated smoke tests against those exact images. `scripts/ci.py check` identifies images by committed `HEAD` and may reuse its published images; running it on a dirty working tree cannot by itself establish that the uncommitted runtime was exercised. After committing, the normal clean-checkout CI must build and accept the committed version before rollout.
+
+### Event boundaries, vocabulary and pinned references
+
+An event follows one occurrence, its direct consequences, responses, investigation, corrections and remediation across months or years. A new occurrence, independent decision/action or statistical period starts another event. A market reaction explicitly attributed to a particular release belongs to that release. Shared subjects or TAGs establish candidate relevance, not membership.
+
+Candidate recall also matches whole ASCII words from literal compound aliases against event TAGs and titles, so an existing `bybit` TAG can be found from `Bybit Hack` without regenerating historical keywords. Full-phrase matches rank first, retired events are excluded and the sixty-candidate cap remains. The model decides membership. New keyword extraction keeps independently searchable subject names alongside incident phrases. Research quotes must retain enough continuous original context to support the claim, including original line breaks around names; literal substring validation alone does not establish semantic support.
+
+`GET/PUT /api/risk/tag-vocabulary` reads/saves the reviewed phrase vocabulary. PUT accepts `{base_revision, entries: [{canonical, aliases}]}`; stale revisions return 409, ambiguous or invalid entries return 422. Each save creates an immutable snapshot in the additive `news_research_vocabulary_versions` table (migration `b81234567890`, following `a71234567890`). The homepage provides manual editing. Vocabulary changes expand historical searches without rewriting prior model output or triggering paid reprocessing. Attempts and event research freeze their vocabulary snapshot; literal news aliases and quotes remain unchanged.
+
+`GET /api/risk/events/{event_id}/versions/{version_id}` reads a successful pinned version, including frozen member articles and references; a mismatched event or unsuccessful version returns 404. Reference links open that snapshot. Current target changes are marked but do not enqueue referring events.
+
+`scripts/accept_news_research.py` runs only against an empty local disposable database with CI credentials and an explicitly supplied private model configuration. Use the frozen 30-news report or `backend/tests/fixtures/news_research_scenarios.json` (`--synthetic`). Separate databases share a `--budget` counter file, which atomically limits all provider requests, including retries and repair/tool/extraction rounds, to 240. Never reset the counter for the same acceptance run. The script reports automated assertions separately from human quality review and never automatically grants quality acceptance. Synthetic external searches are controlled; real-source availability limitations remain visible. Reports retain exact inputs, outputs, rules, vocabulary, evidence and usage; private provider configuration must be removed after the run.
+
+### Chronological scenario acceptance
+
+`accept_news_research.py --scenario-manifest MANIFEST --credentials PRIVATE --output RUN_DIRECTORY --budget NEW_COUNTER` freezes twelve real originals and chronological batches. The manifest specifies explicit same-event, separation and pinned-reference expectations, official URLs with text anchors, and the immutable historical counter hash (199). The independent new counter permits 90 requests initially; `--resume --finish` permits the reserved continuation up to 120 additional requests total. All retries, repairs and tool rounds share this counter; never reset it. Reports and attempts are retained separately, while `state.json` holds resumable progress.
+
+After an explicitly authorized budget extension, `--resume --finish --request-limit LIMIT` sets the cumulative supplemental cap for that continuation and records it in the new state/report. It never changes the frozen manifest or resets the counter. Omission retains the original 90/120 defaults; the option is rejected without both resume flags or below 120. A counter already above the selected cap fails explicitly. Completed-checkpoint restoration retains the extended cap from its report; paid continuation still needs the explicit authorized limit. Authorization remains an operator responsibility.
+
+Only the disposable local CI database is writable. Published isolated Skills use the same configuration path as runtime; both the base instructions and published content must reach the model. Original news enters the test database one batch at a time. External tools are disabled during historical replay; final live verification publishes an isolated Skill version with explicitly supplied official URL hints, which are leads rather than evidence. These explicit reruns do not count as natural revisions. Known public URLs may be read directly through the same DNS, redirect, size and tool-budget checks. Tool snapshots distinguish `discovered` and `direct` reads. Search availability and successful official text reads are assessed separately.
+
+The manifest, configuration, vocabulary and existing originals must remain frozen for resume. A diagnosed missing incident reference can use `--resume --finish --repair-references` before the final natural-update batch: retain the old version, publish a repaired isolated Skill, and retry the affected consumer without repeating successful TAG extraction. This explicit repair is retained in the audit and is not evidence of autonomous recovery. Automated checks never grant human quality acceptance; limited acceptance requires review of facts, timelines, rating rationale, original quotes and immutable references. No result establishes long-running production quality, autonomous URL discovery, or savings. Live migration, deployment and real Skill publication remain separate actions.
+
+Official-evidence checks require a successful version of the intended event, a successful read from its expected official domain with the frozen fact anchors, and a supported/partial claim citing that read's literal text. A read retained only in a failed version cannot pass. Each event receives only the official leads associated with its member news; unrelated official pages are not required reading. Reference checks require a later natural target update without another consumer attempt and call the application reference reader to verify that the pinned version remains unchanged while `changed=true`.
+
+Resume requires the disposable database as well as report files. If that database has been removed, `scripts/restore_news_scenario.py --report ORIGINAL_REPORT --snapshot COMPLETED_BATCH_SNAPSHOT --credentials PRIVATE --output NEW_RUN_DIRECTORY --budget ORIGINAL_NEW_COUNTER` restores a completed chronological prefix into an empty local `ci` database with synthetic CI credentials. Apply migrations to that isolated database first. The restore checks historical versions, originals, vocabulary and checkpoint consistency, preserves successful keyword attempts, and carries forward the original counter without resetting or spending requests. Historical rules stay frozen; subsequent work uses newly frozen isolated Skills and requires separate real-model validation. Old reports are never overwritten. Offline mock replay demonstrates code behavior only and cannot grant quality acceptance.

It uses the deployment lock and does not start the worker or enable models. Deploy through the normal `scripts/deploy.py update` path, then configure, publish and enable from the UI. Do not roll back to pre-scope code with enabled news Skills: pause news AI and disable news-scoped nodes first, since older code does not understand that boundary.

+preserves its cursor; restarting a completed traversal scans it again. Official
+rounds wait for the previous checkpoint commit and reload current source settings
+and cursors from the database; queued messages cannot restore canceled history
+or bypass a newly saved failure backoff. A failed checkpoint write is retried on
+subsequent triggers, with three total write attempts per round; exhausted writes
+block new collection with an explicit error until the collector is restarted. An ended
+list traversal does not prove complete bodies or attachments. Attachment failures
+remain visible on the news item, with up to three scheduled attempts one hour apart;
+exhausted gaps require explicit investigation or another traversal.
 
-### Complete news units and exclusive rechecks
+Article and DOJ document failures also remain explicit gaps, with at most three
+scheduled attempts one hour apart, measured from the actual failure time.
+Real-time and history lanes share the document retry quota; a document retry is
+requested only once per round. Due body and attachment retries remain eligible
+after their document leaves the real-time lookback window.
+A failed round may reuse completed document
+reads and retain retry evidence, but cannot advance its lane or history position;
+a pipeline error prevents saving completed reads. HTTP 403/429 and detected
+challenge pages stop the round for at least fifteen minutes; a longer valid
+`Retry-After` is honored and subsequent blocks cannot shorten that deadline.
+CFTC document requests are serialized with a three-second
+delay. The console distinguishes active collection, scheduled waiting, failure
+backoff, stopped processes and unresolved document gaps.
 
-Grouping retains each coherent publication as a complete news unit: related metrics and background remain inside the package. Independent developments remain separate. Local research accepts up to six keywords and ranks partial matches; search outages are distinct from successful empty searches. Planned dates and statistical periods remain separate from actual occurrence timestamps.
+Real-time discovery follows pagination, including every Federal Register page
+within a day. Only verified descending feeds stop early at a fully dated page
+outside the lookback window; unknown ordering is traversed conservatively.
+Treasury currently returns the first page again for subsequent page requests.
+A dated real-time page can end discovery at the lookback boundary; a repeated
+historical page still fails explicitly and cannot establish historical coverage.
+Congress screening reads subjects, CRS summaries, and available text before
+excluding a bill whose title alone is inconclusive. Missing bill evidence remains
+an unresolved gap, retried at most three times one hour apart per official update;
+exhausted gaps remain visible in the collection console. No AI is called.
 
-Reading ranks all important inputs, shortlists at most twelve low-star candidates across domains, selects up to three expansion entries, then synthesizes once. Saved priorities are reused by synthesis.
+Original documents remain separate news packages across publishers. Body and
+attachment text are searchable and versioned. Date-only releases are displayed as
+dates, not precise release instants. Backfilled documents describe the version
+available at capture time; they are not historical point-in-time evidence.
 
-Reprocess previews accept `selection=attempted` to freeze distinct previously attempted news IDs at their latest source hashes and force regrouping. `run_mode=history_only` requires paused, idle AI; startup uses the existing three-stage validation gate, enables only this durable batch, and pauses on completion, cancellation or failure. It does not consume realtime backlog. Grouping finishes before downstream review; completion also waits for the final reading snapshot. Existing range/shared behavior remains the default. These additions use existing JSON storage and require no schema migration.
+Selection rule `us-policy-v2` uses explicit national budget, continuing/consolidated
+appropriations, discount-rate and reserve-policy phrases instead of standalone
+`budget`, `fiscal` or `quantitative`. Federal Register macro screening uses the title
+to avoid incidental references in unrelated regulations; crypto screening still
+reads the complete body and extracted attachments.
 
-An exclusive batch also enrolls unfinished member packages required by its events, using the same frozen configuration. This may add package reviews beyond the selected news; unrelated realtime work stays queued. Failed members remain failed until explicitly retried. Any grouping, package or event failure blocks advanced reading generation. The first exclusive start initializes the dispatch boundary while preserving an existing boundary. Event plan dates must match the verified time point's precision, original time text and at least one corresponding time quote.
+Image attachments remain an explicit text-extraction gap, including when their
+format is PNG, JPEG or GIF. They do not establish completeness or irrelevance.
+Relevant documents remain `partial`; documents whose relevance is still unknown
+are kept in bounded attachment retries rather than inserted as unrelated news.
+Congress meeting attachment failures retain the same retry evidence as articles.
+Bill and attachment retry records retain an optional `error` explaining missing
+dates, unavailable text formats or extraction failures. The console shows these
+reasons, original links, attempt counts and pending/exhausted state even while a
+new round runs. Historical records without a reason remain visible as such; this
+change neither resets their retry quota nor rewrites historical records.
+`unresolved_bills`, `bill_retry_pending` and `bill_retry_exhausted` are derived from
+the persisted bill retry cursor, independently of the latest round's statistics.
+The source API derives `attachment_gaps`, `attachment_retry_pending` and
+`attachment_retry_exhausted` from the persisted cursor, independently of the latest
+round's statistics. The console keeps these document counts visible across rounds;
+success clears the gap, while three failed attempts remain visible for investigation.
+
+Validation without production credentials:
+
+- `cd backend && uv run pytest && uvx ruff check --select F,E9,B src tests`
+- `cd web && pnpm lint:check && pnpm typecheck && pnpm test && pnpm build`
+- `scripts/smoke_us_news.py` requires an isolated PostgreSQL database with user
+  `ci`, password `ci-only`, database `ci`, host `127.0.0.1`; it creates its own
+  news tables and must run in an empty disposable database. Redis publication is mocked.
+
+The 50 public HTML fixtures cover eight publishers. Eight additional Fed
+discovery responses were captured on 2026-11-04: the 2025/2026
+press, speech and testimony archives, FOMC calendars and H.4.1 release dates.
+Their offline regression checks configured entry URLs and article discovery;
+Fed speech archives use the singular `speech/` directory.
+Three captured policy bodies cover implementation notes, economic projections
+and meeting minutes. Minutes use the calendar's explicit release date, with its
+source URL recorded, rather than the meeting date encoded in the document URL.
+Date-only documents remain eligible on the cutoff day; older discovery links
+are filtered before fetching their bodies in both realtime and history lanes.
+Additional API/PDF fixtures cover three 2025 DOJ institutional cases (OPA and USAO), their four attachments,
+one excluded personal crime case, and a Federal Register daily XML containing 106
+unique document numbers. The isolated database smoke checks idempotency and
+revisions after API-package edits. Three additional
+packages are actual GovInfo bill XML texts for GENIUS, CLARITY and STABLE;
+this cross-check is separate from the captured Congress API responses.
+The Congress API fixture contains 39 successful responses and produces 100
+packages: GENIUS 52, CLARITY 37, STABLE 10, and one crypto committee meeting.
+The smoke also replays those API packages without network access. On 2026-11-04,
+the isolated PostgreSQL run finished with 156 news packages and 158 revisions;
+replaying unchanged inputs created no extra revisions, and two deliberate edits
+each created one revision.
+
+DOJ discovery uses the public news API with 50 metadata records per page, then
+fetches individual bodies by UUID. It traverses publication dates newest first;
+old HTML discovery cursors are rebuilt without deleting news or changing the
+history target. API attachment file IDs use the verified official `/media/{id}/dl`
+endpoint. Calendar publication dates remain date-only; official update timestamps
+are stored separately.
+
+Federal Register daily results above 2,000 use the GovInfo issue XML to enumerate
+unique document numbers, then reuse the document API/body/PDF path. The issue date
+and unique count must match the daily API total; mismatch or download failure does
+not advance the checkpoint. A day advances only after its pending documents finish.
+Overflow tests use constructed 2,001-document data, not a claim of a real overflow day.
+
+An independent test key completed the three bill parser chains and a selected
+crypto committee meeting on 2026-11-04. This verifies the sampled API/text/action
+and attachment paths, not complete historical discovery or full source quality.
+The report keeps `accepted=false`: GENIUS has one undated text version, and one
+meeting PDF has no extractable text. Production credentials were not used in
+tests, and no key is hardcoded into the collector or saved in the fixtures.
+
+Three Federal Register API/body/PDF documents were previously read successfully
+on 2026-11-04; font encoding fidelity was not independently verified. Fixture replay
+and limited live reads do not prove complete 2025 coverage or authorize production
+collection activation.
+
+The GovInfo GENIUS BILLSTATUS XML captured on 2026-11-04 confirms that the
+Enrolled Bill version has an empty date. The offline cross-check preserves that
+gap and validates a dated text from each of the three bills without inventing a
+date. A dated version without a supported format also remains a bounded retry
+gap even when other versions succeed. Meeting PDFs include both meeting documents
+and witness documents, deduplicated by URL. The selected real meeting lists 16 PDF
+entries with 15 unique URLs: 14 yielded text, while a Truth in Testimony form did not. The meeting
+package remains `partial`; no OCR dependency or invented text/date hides the gap.
+
+Earlier public-key probes returned HTTP 429 and stopped immediately. The
+independent test key resolved that access blocker. Do not reuse production
+credentials for this test.
+
+
+Resumable Congress acceptance capture (no database, Redis, model, or production
+configuration access):
+
+```sh
+PYTHONPATH=backend/src backend/.venv/bin/python scripts/capture_congress.py --cache /tmp/alphapulse-congress-acceptance/responses.json.gz
+```
+
+For a separate local test key, enter `CONGRESS_TEST_API_KEY` in the ignored,
+mode-0600 `/srv/AlphaPulse/.env.congress-test`, then load it with uv:
+
+```sh
+PYTHONPATH=backend/src uv run --project backend --no-sync --env-file /srv/AlphaPulse/.env.congress-test python scripts/capture_congress.py --cache /tmp/alphapulse-congress-acceptance/responses.json.gz --meeting-url https://api.congress.gov/v3/committee-meeting/119/house/119541
+```
+
+The script uses `CONGRESS_TEST_API_KEY` when separately configured, otherwise the
+public DEMO_KEY. It atomically saves each successful, credential-redacted response,
+reuses cached responses on another invocation, and stops on HTTP 429 or its bounded
+request budget (default 60, maximum 100). It never follows redirects with API
+credentials. A separate compressed report records incomplete cases; an incomplete
+run exits nonzero. GENIUS's known undated version remains an explicit gap rather
+than a passing complete case. Meeting selection requires a crypto-relevant title
+or related metadata; `--meeting-url` accepts a known official single-meeting API
+URL to avoid an unrelated meeting scan. `parser_accepted` means the selected
+callback chain finished, including explicit partial packages; it does not mean
+full source quality passed. Exhausted candidate/request budgets remain incomplete.
+Mocked tests and real captured responses are separate evidence; neither proves
+complete 2025 coverage or authorizes production activation.
+
+### Bounded collection failures (November 2026)
+
+SEC, DOJ and Congress use one durable retry layer (three failed attempts, at least
+one hour apart). EIA, DOL, Michigan and ADP retain the same budget per calendar
+release in `collection_failures` / `collection_retired_at`. Cooling does not spend
+an attempt. Retirement retains evidence and values; new releases are independent.
+A source is disabled only after three failed discovery/schedule checks, not for
+one document gap. Explicit official photo captions can exclude illustrations from
+text extraction. Missing official dates are never replaced by update timestamps.
+
+Migration `db2345678901` is additive and must precede activation. With the crawler
+stopped under the deployment lock, preview `python -m
+alphapulse.crawler.repair_collection`; append `--execute` once to establish the
+repair budget for existing news gaps. It preserves the previous retry evidence
+and records a durable initialization marker. Repeating it cannot renew the budget.
+Set the authorized SEC contact in the private instance environment before enabling
+SEC; do not put the address or credentials in tracked configuration.
