+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。"""

+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；原文中的其他事件只作背景。
+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。
+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。

 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。'''),

+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。
-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。
+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。
-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。'''),

-## 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.
+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 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 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 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.
+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.
 
-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.
+### First rollout of two-stage research
 
-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.
+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.
 
-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.
+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 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 following steps are prepared operator instructions, not an instruction to run production changes without authorization:
 
-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.
+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.

+### Isolated acceptance and original-data protection
 
-The additive `b2c4d6e8f012` migration requires separate authorization and pauses the existing news AI setting.

-```sh
+Real-news acceptance requires explicit permission for the bounded sample and necessary model access. Export original records in a read-only repeatable-read transaction, copy only necessary provider fields to a private isolated configuration, and never copy the production `.env`. After processing, review keyword coverage, event boundaries, reposts, evidence, dates and ratings, retain a credential-free report, and remove temporary keys and test containers. The initial November 3 round used thirty news items and additive tables only; the subsequent chronological supplement uses twelve frozen originals and a separate additional request budget. Legacy sample replay/reset commands target a different schema and are not part of this workflow; do not run them for this transition. Legacy reports and task counts do not prove current quality or savings. Missing usage is not zero cost.
-python3 scripts/deploy.py reset-news-ai --build /path/to/accepted-build.json
-```
 
-After explicit maintenance authorization, the same command with `--confirm-delete-old-news-ai` stops the news worker and clears only `risk_analyses`, `risk_events` and `risk_snapshots` in one transaction. It refuses if the new pipeline already contains data. It preserves provider configuration, source news, revisions, calendar, Skills, Chat and trading. 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. Downgrading the additive migration drops the new AI tables and requires an independent data-retention decision.
+News transport uses at most two retries after 30/60 seconds, honoring valid Retry-After up to 120 seconds while retaining the worker slot. Partial output and permanent failures are not replayed. Structural submission repair is bounded to one correction using already available evidence. Default Skill changes are not automatically published to live nodes. External search must use a working test endpoint to establish external-verification coverage; unavailable search is explicitly reported.

-### News AI concurrency
-
-All background news AI stages share `risk_settings.max_concurrency` (default 5).
-A slot covers one complete stage task, including its sequential model and verification
-calls. Completed tasks release their slots immediately; runnable real-time stages rotate
-before historical items use spare capacity. Pending work remains in PostgreSQL.
-
-The home settings dialog saves this operational limit independently of model settings.
-Increasing it admits more work; decreasing it drains existing tasks without cancelling
-paid requests. Pausing stops new admissions. The overview reports active slots and stage
-counts; an expired worker heartbeat shows an unknown active count.
-
-`PATCH /api/risk/settings/concurrency` accepts a positive integer `max_concurrency`.
-The limit is excluded from frozen reprocessing configurations and model fingerprints.
-“Test and enable” requires paused analysis and an idle pipeline; an exclusive PostgreSQL
-advisory gate prevents concurrent validation and background work. Historical items persist
-individual states, so completion order does not change progress or skip unfinished items.
-
-Migration `e5f701234567` adds the limit and converts legacy historical checkpoints to
-item states. Deployment and execution of this migration require separate authorization.
-
-### Historical news AI backfill and queue
-
-The home page's **AI 历史回补** selects publication times in `[start, end)` using
-stored current news revisions. `missing` completes unfinished grouping/package analysis
-and reuses published successes; `review` explicitly repeats grouping/TAG and package
-verification, preserving previous successful versions. Selecting both includes all
-news in the range. Related event timelines are refreshed; a batch waits only for its
-own package/event targets, while the home reading window stays at 72 hours.
-Corrections register every resulting package in the same transaction, including new
-branches when a split retains the original ID. An empty reading window saves a cleared
-snapshot without a model call or concurrency slot.
-
-`POST /api/risk/reprocess/preview` accepts `start`, `end`, and `modes`. Its opaque
-`preview_id` expires after 15 minutes and fixes news IDs, content hashes, models,
-reasoning efforts, and published Skills. `POST /api/risk/reprocess` accepts that ID;
-changed configuration requires a new preview, and changed source content fails its
-individual item explicitly. A missing item completed before execution is skipped.
-Only one batch runs at a time. Batches use spare slots in the shared concurrency
-pool, respect global AI pause, support cancellation of further news admissions and
-explicit retry of failed items, and reclaim interrupted news items after restart.
-Already scheduled downstream package/event updates continue after cancellation.
-An in-flight news item also keeps its identity reserved after cancellation, so a new
-batch waits for that item to finish while unrelated news can still use spare slots.
-
-`GET /api/risk/reprocess/{id}` returns paginated per-news states and downstream
-stage counts. `GET /api/risk/queue` filters by `state`, `stage`, `origin`, `job_id`
-and page. The home queue refreshes every three seconds while visible. Actual model
-waits, research rounds, tool calls and save steps are transient telemetry under
-`ap:risk:active`; PostgreSQL remains the durable queue. Heartbeat expiry means unknown
-execution state. Empty outlook polls and batch completion checks do not consume AI
-slots or appear as running model tasks.
-Batch filters include durable package/event targets even after real-time updates
-change their execution configuration; displayed model/source metadata describes the
-current execution. Open news details refresh with the batch list, retaining their page
-and rejecting responses from an older selection or session.
-
-Migration `f60123456789` adds normalized batch news items and package/event targets,
-retaining legacy job JSON and execution semantics. Isolated acceptance includes
-`scripts/smoke_backfill.py`; it mocks all model/Redis I/O and checks mode behavior,
-frozen previews, source changes, target completion and queue queries. Live migration,
-deployment and real backfill execution require separate authorization.
-
-### Complete news units and exclusive rechecks
-
-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.
-
-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.
-
-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.
-
-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.
