+

+

 ## 当前路线
 
-- 使用 Electron 开发 Windows、macOS 双平台桌面端。
-- 以 Playwright 固定执行为主线，Midscene 作为可选辅助；学习后台以 A2A learning 的适用模块为基础裁剪适配，桌面壳另行提取验证。
-- 学习端围绕少量平台操作完成观察取证、结构化整理、候选生成、固定校验、变参试跑和版本发布，运行异常回流维护端修订。
+- 当前按功能模块逐层盘点小红书网页版入口，把可复用操作分别固化，再按平台/任务类型路由；桌面阶段采用 Electron，同时面向 Windows 和 macOS。
+- 已确定学习与桌面共用 Playwright 固定执行、同一版本合同及结果核对，不另建 browser-use `Agent.run` 路径；Midscene 仍是后续可选辅助。学习后台以 A2A learning 的适用模块为基础裁剪适配，桌面壳另行提取验证。
+- 学习端按页面类型和入口来源记录层级、下级控件及返回路径，分别完成观察取证、候选生成、固定校验和变参试跑；运行异常回流维护端修订。
 - 首期由开发者与本地 Codex 协作学习：维护者在平台页面登录，Codex 观察、编写参数化实现、提交候选并依据校验和试跑结果修订；后台管理证据与版本。后台内置自主学习 Agent 后续按需求建设。
 - 学习后台使用独立 PostgreSQL，检索库准备 `pg_search` 与 `pgvector`；商家桌面端仍按 SQLite 规划。平台账号在官方页面自行登录，每个账号复用专用浏览器资料目录。
 - `browser_use` 测试工程的 Electron 桌面壳、产品认证和管理后台作为候选复用基础；云端可沿用其 FastAPI 骨架，本地 SQLite、获客执行与商业模块按当前方案适配或新增，范围见整体方案第 4.4 节。
 - 模型由我们在运营后台按文本判断、复杂复核、视觉操作等用途配置，不绑定具体型号。
 - 第一条学习链路选定小红书「搜索笔记 → 详情 → 评论读取」，先用本机演示页跑通学习与验证，再在维护者自行登录的平台页面上适配。
+- 新小红书任务默认“有界网页操作（原生通信）”，也可明确选旧模式作对照。新模式只允许已观察唯一搜索输入/回车、固定官网标准笔记链接和普通区域有界读取；15 秒动作窗口内，当前主框架发起的第一方 HTTPS `xhr/fetch POST` 自然通信（包括安全通信）可正常进行。它不是网络沙箱，也不承诺服务端绝无副作用；不直接请求接口、运行任意 JavaScript 或添加指纹伪装。旧模式（legacy）的四类精确请求策略原样保留。
+- 当前浏览器执行为 Playwright，尚未接入 browser-use。平台提醒的识别、暂停与人工恢复需按真实页面补齐；任何浏览器框架都不作为不会被识别或限制账号的保证。
+- 学习探索记录与正式运行模式验证分开：已实现运行前基线、观察窗口、人工追加反馈和候选质量状态；晚到异常保留原记录并将同版本置为待复核。当前只评价维护环境，平台自动提醒识别、真实平台表现与商家发布仍待验证。
 
 ## 项目状态

+
+在已取得可用正文并通过来源核对的阅读详情中，点击“分析本次已读内容”。这会分析该条已保存的文字，不重新打开或操作平台。正文与每条首层评论分别给出明确需求、疑似需求、普通讨论或信息不足，并保留逐字依据、来源、缺失信息、模型配置和请求记录。纯图片/视频标为信息不足、内容未解释；需求信号不等于已确认客户。失败阅读不能分析，有正文的有效部分阅读会保留范围说明。
+
+新版另列当前角色信号、多选表达、业务相关性及根据商家条件派生的初步匹配和建议。“自身要装修”可同时“提问、求建议”；服务方也可有自身需求，短句“哪里”不确认角色。阅读默认沿用关联条件，旧阅读可选择已确认条件追加新分析；条件摘要参与结果复用，旧分析仍可查看。地区或上下文不足会提示补充信息。建议未执行。
+
+新分析合同为 `renovation-demand-v4 / demand-result-v3`。评论通过服务端生成的 `context_refs:["note"]` 引用同次阅读的笔记，笔记没有背景引用，正文只向模型提供一次；总范围仍为21个来源、16,000字。新增独立 `consultation`（有／无／信息不足），本条逐字依据与笔记背景依据分开保存，不能引用其他评论或继承作者的身份、需求、项目地区和预算。程序派生“保留待核实”等展示结果，不据咨询意向提升业务匹配或触发联系；这也不是独立线索库。新旧提示和结果版本隔离复用，不重写旧分析。

+note代表笔记作者；comment_N仅代表该条评论者。每一来源的自身事实独立，不能继承作者、其他评论或商家条件中的需求、地点、预算和身份。仅可按context_refs引用同一阅读的note背景理解咨询对象与业务相关性，不能据此补评论者自身事实。内容中角色只是当前发言信号，绝不是账号身份核验或已确认客户。
+demand分类针对发言者自身当前或未来装修需求：explicit=明确自己准备/需要装修或找装修服务；possible=有自身需求信号但不足；discussion=讨论、询问别人、服务推广、建议、已完工分享等没有自身需求信号；insufficient=信息不足。explicit/possible必须有self_need表达。询问和自身需求可共存：我家准备装修，问大家顺序，是explicit且self_need、question、seek_advice；你开始装了吗是discussion和question。不能仅靠装修词或问号判断自身需求。
+role只选suspected_demand_side（当前发言有自身需求信号）、suspected_service_provider（有本人明确提供/推荐服务信号）、participant（建议/经验等参与）、unknown。仅“哪里”“你是哪里的嘛”不足以判断服务方，role应unknown；询问地点不是说自己有需求。“我有设计师朋友推荐你”可有服务提供信号，但不表示自己要装修。服务方也可能表达自身采购/装修需求，此时role与self_need不互斥。
+expressions是可多选的表达，type只可self_need/question/seek_advice/service_offer/advice/case_share/other/unknown。question包括询问别人和自己求问；seek_advice为求建议；service_offer需实际提供/推荐服务信号，不凭“哪里”推断。unknown只能单独出现。
+business_relevance判断本源文字与business_context.service/target_customer的业务内容是否相关，value只可relevant/irrelevant/unclear；可借context_refs理解短句的咨询对象，但relevant/irrelevant仍必须引用本源文字；unclear可空。相关不等于该发言者自身有需求，不能将商家条件当作引用或捏造地点。排除服务推销由程序处理，不妨碍服务方同时有自身需求。
+stage/region/budget只提取发言者自身需求的阶段、项目地点和预算，返回{"value":"原文字词","evidence":"包含value的逐字原文"}，否则null。评论中的“你是哪里的”没有自己的地点；设计师所在地、服务覆盖地、对方项目所在地不能作发言者自身需求地点。没有自身需求时这些字段必须null。不得从service、region或提问对象补事实。媒体未提供，不能解释、OCR或依据图片推断无需求。
+只返回JSON对象，唯一顶层键results，数组恰好覆盖每个输入source_ref一次。每项恰好包含source_ref,demand,evidence,role,role_evidence,expressions,business_relevance,stage,region,budget,consultation。
+evidence为1至3条本源逐字原文，role_evidence为0至3条（非unknown角色必须有）；expressions为1至6项，每项恰好{"type":"固定枚举","evidence":["逐字原文"]}，不同type不能重复，非unknown必须有1至3条证据。business_relevance恰好{"value":"固定枚举","evidence":[]}。所有引用最长1000字，事实value最长120字，不改写引用、不输出自由推理或额外字段，只处理有文字的来源。""" + CONSULTATION_PROMPT_APPEND

 ## 当前状态
 
+- 当前主线为学习、固化、轻量召回及变参执行，按维护者要求扩展小红书网页版功能入口与页面层级；“平台路径”首批33项模板中18项有可核对观察。发布者主页导航已通过，评论者主页最终复验在官方安全验证处暂停，尚未固化新导航候选。业务识别扩展暂停，历史保留；最新事实见2026-10-25-11。
+
 - 已有 React/TypeScript 学习后台、FastAPI API、Node.js Playwright 工作进程。
 - A2A 学习后台的适用页面与组件已裁剪迁入；原工程保持只读。
 - 学习账本已接入独立 PostgreSQL 17。检索库准备 `pg_search 0.26.1`、`pgvector 0.8.6`；SQLite 保留作离线开发和测试适配，原数据及备份保留。
 - 管理员在空账号库初始化为 `admin / 123456`，已有账号和密码不随启动重置。
-- 已支持人工确认会话、采集证据、记录参数化步骤、生成不可变候选、静态校验、实际试跑及追加验证历史。
-- 首期学习方式已确认为维护者与本地 Codex 协作：Codex 观察、编写、修订和验证，后台保留资料。未完成真实小红书学习，也未实现后台内置自主学习 Agent。
+- 已支持可见页面登录检测、人工确认会话、采集证据、七类有界动作、动态目标、有界容器目标定位、集合等待、容器内行读取、有界分批去重、明确空态合同、不可变候选及静态/探索/正式验证。逐批截图绑定摘要，失败保留实际前后及已得批次证据；质量复查有直达入口与待办。
+- 首期学习方式为维护者与本地 Codex 协作。旧 8 步候选正式试跑因首张卡片无标题超时，保留为待复核；新 7 步分批候选静态及两组正式执行通过，分别读到 3/4 条首层评论并登记过程复查，原正式阶段为 42 份观察、7 步和 3 条验证。已登记窗口内正常反馈，仍待到期后的实际复查，未提前登记无异常完成。此后单篇衔接的新增验证见最新记录；没有后台内置自主学习 Agent。
 - 第一条目标链路为小红书「搜索笔记 → 详情 → 评论读取」。平台自动身份核验、完整独立来源读回、正式发布分发、Electron 商家端、macOS 实机验收及商业 AI/计量仍未完成。
-- 最近已执行的工程验证为：后台套件 28 项通过、浏览器工作进程 12 项回归通过、PG + Edge 本机演示页端到端通过、检索扩展烟测通过。具体边界与证据见下文；这些阶段计数不累加，也不表示本轮重新执行。
-- Git：基建代码与此前文档已提交并推送至 `origin/main`，主实现提交为 `cd34154`；本轮同步结果见第 07 条，后续文档回写以实际远端提交为准。
+- 装修内容初筛已接入维护后台：独立四步搜索读取有界列表，规则保留少量笔记；可逐篇接入正文/首层评论，点击前后核对笔记编号，独立保存阅读、部分结果、验证与证据。旧离屏、超时及文字必填遇图片的失败保留；新文字/媒体内容合同和阶段耗时已接。限定当前定位检查后，同一新八步候选两篇探索约 46/49 秒完成，各取得正文及 6 条首层评论，其中一篇为 5 条文字和 1 条纯图片，媒体未解释。已接模型独立分析文字，原文依据逐条校验；实际身份与需求、准确率及实付费用仍待核实，地区不作自动过滤。
+- 模型采用服务端可配置的官方 `deepseek-flash`，本机已配置两个不同 Key、一个优先一个备用，默认关闭思考。两篇已有阅读各保留 v1/v2/v3 分析；新版增加独立维度，询问他人进展/推荐设计师不再当作自身需求，歧义项仍人工待核。分析不操作平台，原阅读/候选不变；未做已确认客户或模型准确率承诺，未调用真实备用 Key 强制试错。
+- “内容初筛”新增商家需求工作台：自然语言逐字段提取、原文依据与缺项、维护者显式确认追加版本、固定首词初筛及阅读衔接；schema 8 保存不可变商家条件。新版分析独立区分角色信号、多选表达、自身需求及相关性，程序按条件派生匹配和展示建议。未知地区不默认全国，不能改传关键词/地区覆盖确认条件；旧记录及原失败保留。已对两条已有真实阅读追加 v3 分析，未重新操作平台。
+- 分析历史“查看分析”点击直接打开详情侧栏，同条可关闭重开，原文、维度和依据优先，技术配置及用量折叠。已接人工核对、五轴纠错、逐字依据、追加修订和最新版本统计；查看/预填不自动保存，不调用模型。首批 3 项用户对话核对已注明来源代录：正文确认 1、首条评论表达纠错 1、第二条评论暂不能确定 1；仅 2 项计入已判定，首篇余 4 项及另一篇仍待核，没有扩大到账号真实身份或地域匹配。下一步建议未执行关注/私信/评论。
+- 08–09阶段记录：“案例或服务展示内容 → 评论者自身需求”已完成新模式首篇探索回放：`playwright-xhs-native-ui-v1` 实录9步，四步搜索及八步正文/评论候选均静态通过；八步一次完整回放通过，来源绑定正确，取得正文和2条完整首层评论，3批范围截断。原legacy失败保留，新搜索初筛尚未独立回放；正式运行质量、账号延后反馈与更多样本仍待完成，详见 2026-10-25-08。
+- 最近一次完整后台仍为上一阶段 **164 passed、无跳过**。2026-10-25-02 阶段观察等价 **20/20**、最终批次截止目标 **12/12**、SQLite/专用 PostgreSQL/RPC 目标单轮 **11 passed**；该阶段完整 worker **69/69** 在最终复合边界补丁前启动，最终差异由 12 项目标另验，不能称为最终冻结后单轮全量。此前分页策略 **650 断言**、整页目标 **3/3**、清洗 **2 passed** 保留，不累加。未重跑迁移、检索扩展、前端构建或 macOS；账号后续反馈、独立读回、真实标注评测与交付仍未完成。
+- 最新等待前置目标为 **92 断言**，含 20 个官网元数据纯边界场景，另有 1 次本机 Edge 集合自然出现的等待；不是真实官网端到端，本轮未重跑上述旧阶段全量。详见 2026-10-25-03。
+- 本轮范围等待最终本机 Edge **20/20 组、235 断言**，后台 **14 passed、无跳过**（SQLite/专用 PostgreSQL），界面隔离 **7 项通过**，TypeScript 检查及前端生产构建通过。均不替代真实平台复验，不累加前轮计数；详见 2026-10-25-04。
+- 请求拒因与失败诊断已加载，旧记录不补造原因。Playwright工程验证保留07阶段完整 worker **69/69**、新配置目标 **16组/809断言**、后台 **13 passed**、隔离界面 **11项**，分别统计不累加；09阶段未重跑这些套件。08阅读、旧模型及2条人工核对保留，正文仍未人工核；09仅分析已保存文字，服务重启后平台窗口已关闭，没有重开或要求账号确认。
+- 已实现独立咨询意向、有界笔记背景及保留待核展示，使用 `renovation-demand-v4 / demand-result-v3` 和六轴 `analysis-review-v2`；旧v2分析仍可五轴核对且不补字段。最终后台单轮116项、隔离界面13项及前端检查/构建通过，应用贯通集成在最后失败诊断补丁前通过、补丁由最终后台目标覆盖。新版本首次真实输出合同失败保留，补固定无文本拒因后，后续独立分析将2条短评论判为咨询yes/保留待核，实际自身需求、身份、地区和匹配仍不足。没有重现首次失败，不能确定其具体原因；有限结果不作整体稳定性验收，详见09。

 实施规划：本轮仅同步仓库，不改变整体方案第 14 节的优化优先级；下一步仍为本地 Codex 协作的小红书实际链路学习。
 
 提交/推送：主实现提交 [`cd34154`](https://github.com/zwt-cmd/assistant/commit/cd341549dd5fd487afac55425a3e7640f21fc8b0) 已成功推送到 `origin/main`，远端从 `f76f166` 前进到 `cd34154`。前两次直连分别遇到连接重置与超时，定位系统本机代理后，以单次命令代理参数重试成功。本条为推送成功后的进度回写，随后续文档提交同步，最终状态以 `origin/main` 核验。

+## 2026-10-24-01：恢复本机学习后台访问
+
+目标：排查用户反馈的学习后台无法访问，并恢复本机服务。
+
+排查与处理：检查时前端 `5179`、后台 `8810` 均无监听，Docker 引擎可用；通过现有 `scripts/db.mjs up` 确认 PostgreSQL 就绪，再用 `scripts/dev.mjs` 启动前后端。可以确认服务进程此前未运行，尚无证据确定其退出的具体触发因素；本次没有修改应用代码、依赖或数据库配置。
+
+验证：后台 `/api/health` 返回 `ok` 且使用 PostgreSQL，前端首页返回 HTTP 200 并包含应用根节点，前端代理 `/api/health` 同样返回 `ok`。以上是本轮恢复时的检查，不代表永久在线。浏览器工具获取现有标签页时被 URL 安全策略拒绝，未尝试绕过，因此未完成页面画面确认。未重跑功能测试，也未执行真实平台任务。
+
+规划：本轮恢复现有开发服务，不调整整体方案第 14 节的实施顺序。
+
+提交/推送：未执行；仅追加本次故障处理与检查事实，保留此前未提交的规则及文档调整。
+
+## 2026-10-24-02：复核参考学习端与 V8 召回设计，调整对接规划
+
+目标：按用户给出的两个本机路径，重新检查学习后台、学习逻辑和召回逻辑，当前先对齐学习与召回，桌面工程暂后置。
+
+核对事实：参考总仓仍为 `main / db7b54a9c5ad4216df589e307ba57d180e3911af`，与上次相同；学习目录相对该基线及工作区均无修改。C 当前入口已指向 V8，新增/修改位于未提交的设计资料与交付快照；其 README 明确尚无正式应用、服务、迁移或工程测试。不能据“重新拉取”认定 A 有新实现，也不能将 C 方案当成现成召回服务。
+
+源码核对：A 已有操作链知识、参数目录、端内语义映射、正向检索文档和索引代际等基础；正式生产激活及 reader 仍受 `PRODUCTION_CURRENT_STATE_BRIDGE_REQUIRED` 阻断。新语义生成/展示不代表已进入正式索引，当前投影输出仍只支持标量。C V8 细化了能力实现级双路召回、RRF、规则/缺参/当前状态检查，以及输出集合、分页和效果的消费要求；12 组 212 项是条件适用的需求登记，不是全部已实现字段。
+
+本项目差距：现有候选主要绑定任务、样本参数、步骤、摘要和验证，读取输出仍为文本列表；尚无稳定逻辑能力身份、正式输入输出 Schema、语义修订、业务检索投影或实际召回 API。既有三条合成文档及人工三维向量烟测只能证明扩展和基础查询可用。
+
+文档完成：整体方案新增第 5.10 节，规定最小共同契约、精确版本/语义/代际关联、输入输出和对象分页、合格供给、正向索引、同模型同范围双路查询及独立召回验收；第 14 节将契约与召回前移到首条学习并行推进，保留未来双端验收。README 同步当前重点；图解增加“学习与召回”页并明确待实现状态。没有改动应用代码或参考工程，也未引入其依赖、账号或运行资料。
+
+验证：只读比对 Git 基线、相关源码与规格；CodeGraph 工具和 CLI 不可用，使用 `rg` 和源码补证，未创建索引。现有离线图解检查扩展到 8 页，通过节点/路径、文字边界、连线、搜索、主题、窄屏及导出检查，无脚本错误；本机报告为 `.tmp/plan-qa/checks.json`，属忽略的临时产物，不随提交分发。方案复核、文档差异检查通过，22 处本地链接有效；本轮未运行参考工程或应用功能测试，未执行真实模型召回、真实平台链路或业务联调。
+
+下一步：按整体方案第 14.0–14.3 节实现并验证共同契约与最小学习到召回闭环；当前新增内容是设计，不能记为接口接通或检索质量通过。
+
+提交/推送：未执行；保留此前规则和进度的未提交修改。
+
+## 2026-10-24-03：按社媒获客收敛架构，区分探索与交付验收
+
+目标：根据用户补充的获客场景调整当前方案；学习可接受探索中出现提醒，但用户接收的固定链路必须另行验证运行稳定性。
+
+本轮调整：重写整体方案第 5.10、14 节，将当前范围收敛为信息查询、意向线索发现和关注/私信/评论/回复三类任务；先按平台与任务类型选少量固定链路，内容检索在真实网页完成，AI 负责相关性、需求与摘要。A2A 仅参考目标、证据、参数化、版本、验证和修订机制，完整 A/C 协议、三级语义、重型能力召回、通用调度和桌面工程后置。已有 PostgreSQL 和检索扩展保留，不因简化重建基础。
+
+交付质量设计：每版本区分探索记录和正式运行模式验证；探索出现提醒可保留有效知识，不能直接晋级为用户可用。冻结版本按拟交付方式、正常起始会话、明确范围及变化参数独立验证完整任务、结果和平台状态；出现提醒或未知状态时不开放。已开放版本出现提醒时暂停任务并将版本置为待复核，重新验证后恢复。以上均为待实现规则，有限验证不能保证任意账号或未来平台版本永不提醒，也不能量化账号权重。
+
+事实核对：当前实际驱动为 `tools/learning/browser-worker.mjs` 中的 Playwright 持久会话，没有接入 Python browser-use。核对 browser-use 官方配置与真实浏览器文档，其浏览器控制/会话能力不证明小红书或抖音不会提醒。当前没有平台专属提醒检测、正式运行质量门禁或版本停用/恢复实现；未操作真实账号、尝试规避检测或执行跟进。
+
+涉及文件：整体方案、README、方案图解及本进度。同步纠正旧开发顺序中的桌面启动前置；图解将“学习与召回”改为“任务与检索”，补充评论/回复、轻量路由以及探索与交付验收区别。未修改应用代码或参考工程。
+
+验证：方案复核及文档差异检查通过，22 处本地链接有效；离线图解 8 页的结构、路径、文字边界、连线、搜索、主题、窄屏及导出检查通过，无脚本错误，报告位于忽略的 `.tmp/plan-qa/checks.json`。本轮未运行应用功能测试，未验证真实平台提醒率、模型判断、账号状态或跟进效果。
+

+
+提交/推送：未执行；保留此前未提交修改。
+
+## 2026-10-24-04：完成学习端实施方案及首条任务准备清单
+
+目标：在尚未开始真实平台学习时，明确学习端的具体实施、首条任务、操作质量和任务后官方消息反馈验收。
+
+完成：整体方案新增第 5.11 节，规定维护者登录/必要示范、本地 Codex 经受限工具学习固化、现有后台留证的分工；首条限定小红书搜索、详情与有限评论/回复读取。六步流程包含会话确认、正常路径基线、有限探索、固化候选、独立正式模式验证及任务后观察，关注/私信/评论发布继续单独后置。
+
+质量设计：将正常页面路径、动态对象核对、状态等待、输出来源及完整任务纳入验收；后续观察记录官方通知/功能状态基线、预配置复查窗口与时点、检查结果及关联依据。没有弹窗不代表没有事后通知；未检查、等待复查和关联未知不算无异常，延后反馈关联原版本。维护环境的学习验收与未来桌面/双端交付状态分别表达。
+
+实施准备：已有会话、取证、fill/click/read 和候选/基础验证可复用；受限调用入口、有限滚动、条件等待/超时、视口及动态对象核验、结构化映射、只读取数适配、两类验证和后续观察/可用状态仍须补齐。当前已加载 DOM 文本、CSS 可见性及固定短延时不代表已经实现上述操作质量。没有新增通用 Agent 或完整 A2A 系统要求。
+
+涉及文件：整体方案第 5.10–5.11、14 节，README 的实施入口和状态说明，图解的任务后反馈节点及本进度。未修改应用代码、访问真实平台账号或开始链路学习。
+
+验证：只读核对现有 API/worker 与发布预检，方案就绪缺口复核通过；文档差异检查、23 处本地链接检查通过。离线图解 8 页的节点/路径、边界/连线、搜索、主题、窄屏及导出检查通过，无脚本错误；本机报告仍为忽略的 `.tmp/plan-qa/checks.json`。未运行应用功能测试、真实模型、平台操作或账号效果验证。
+
+下一步：先按整体方案第 5.11 节补齐工具和记录状态，以隔离演示样本验证，再启动首条真实小红书有限学习。
+
+提交/推送：未执行；保留此前未提交修改。
+
+## 2026-10-24-05：补齐协作学习工具与维护质量记录
+
+目标：落实整体方案第 5.11 节的通用工具和记录缺口，用隔离样本验证后，再进入首条真实页面学习。
+
+已完成：
+
+- 新增本机受限控制入口，支持任务、会话、观察、动作、候选及质量记录；复用鉴权与 CSRF，限制操作和输入大小，错误不自动重放。维护者凭据从当前进程环境传入。
+- 浏览器新增有界滚动、可见/消失/文本等待、结构化提取和参数化精确目标；检查实际视口、容器裁剪及交互遮挡，零/多匹配停止，动态点击绑定实际对象。输出关联来源和本次读取范围，不将 URL 中的关键词视为正文命中。保留敏感信息过滤、写请求阻止及 EOF 清理。
+- 新候选 v2 记录字段、预算和动态对象，兼容旧 v1；统一冻结与执行的 30 步预算。前后证据、候选及历史保持不可变。
+- 后台和 UI 增加探索/正式模式、基线、服务器起止/到期时间、人工后续观察与候选质量状态。窗口到期不自动通过；晚到提醒/未知关联使同版本待复核，恢复需新的正式试跑与观察。复核发现并修复旧检查延后登记的问题：显式实际检查时间同样须达到观察期限。当前是人工维护核对，没有自动平台提醒识别或商家正式发布。
+- SQLite/PG 新增不可变质量观察表；迁移包含新表，并兼容旧 SQLite 缺表、目标非空拒绝和整体事务回滚。同步现有方案、图解、README 和工具说明，保留此前工作区修改。
+
+涉及范围：`apps/server/`、`apps/admin/`、`tools/learning/`、迁移/端到端脚本、根脚本声明及现有文档；未修改参考 A2A 工程。
+
+本轮工程验证：
+
+- 后台全量 **36 passed，无跳过**，含 5 个实际专用 PG 测试分支；其中浏览器行为使用 FakeWorker。最后两行时间门禁修复后，仅对 SQLite/PG 的质量时序用例定向复跑，**2 passed**；正向到期/恢复用受控时间验证，不是实际平台观察。
+- 真实 Edge 无头工作进程 **20/20**，使用独立本机页面，覆盖新动作/字段、动态匹配、预算/视口、错误断言、Cookie/互斥及 EOF。证据：[工作进程报告](../.tmp/worker-regression-Ln8CCd/report.json)。
+- PG 迁移 **4 项通过**，测试专用库四个随机 schema 均已清理，验证原始 SQLite 与一致备份保留。证据：[迁移报告](../.tmp/migration-regression-j1mfmz2b/report.json)。
+- `test:control` 的隔离 HTTP 传输验证通过，覆盖操作/本机地址限制、CSRF 轮换、拒绝重定向、输入预算和失败不重放；不是实际平台验证。
+- `test:learning` 在专用 PG 随机 schema + 真实 Edge 上通过 API/UI 联动：旧演示链路、7 步动态目标/结构化候选、变参正式试跑、提前无异常登记拒绝、晚到合成通知回退、摘要不变及重启恢复；UI 实际提交正式参数/基线、追加观察并刷新，执行滚动/等待/参数化提取。最终共 7 条验证，页面无脚本错误，发布未放行。证据：[端到端摘要](../.tmp/learning-acceptance-1792810225250/summary.json)。初次验收脚本遗漏首次采集及两处 Antd 测试定位已修正，最终完整通过；未将这些脚本失败算作平台结果。
+- TypeScript 检查、生产构建通过；最后的复查时间标签调整后再次类型检查通过。构建有已有的包体体积提示，FastAPI 测试有 TestClient 弃用提示，均未阻断。
+- 离线图解 8 页检查通过，无脚本错误或几何问题；文档链接及差异检查通过。临时报告和截图在忽略目录中，不作为分发资产。
+
+运行状态：更新后的本机维护服务已启动，API 和前端代理 health 均返回 200、后端为 PostgreSQL，前端首页 200；不代表永久在线。未打开真实平台、代收登录信息、执行关注/私信/评论或测量账号权重。
+
+下一步：按整体方案第 5.11、14.1 节，由维护者在专用浏览器登录并确认，与本地 Codex 观察小红书正常路径，依据页面证据补必要只读请求、字段、分页/空结果及异常分支，再固化和正式验证。真实平台表现、独立来源读回、macOS 与商家交付仍未完成。
+
+提交/推送：未执行；保留此前未提交修改。
+
+## 2026-10-24-06：开始真实首页观察，补齐失败代码诊断
+
+目标：维护者点击登录完成后，由本地 Codex 接续限定链路学习；本条记录实际观察与诊断修改，不记录一般角色解释。
+
+实际情况：
+
+- 指定小红书任务处于人工确认的 ready 会话，初始无观察、步骤或候选。经受限入口采集到真实首页，保留文本与截图；人工确认不等于自动身份核验，也没有检查任务后的官方通知。
+- 用户选择“装修”。现有任务样本 `keyword` 为空且没有参数编辑 API/UI；通过现有 Store 对指定维护者/任务做一次事务补填，条件包含旧值为空、无步骤/候选、并发比较与参数校验，恰好更新一行。保留原观察与活跃浏览器；临时维护脚本位于忽略目录，不声称参数编辑功能已实现。
+- 向已观察到的搜索框执行一次参数化填写，API 返回 409。重新采集后页面出现“装修”搜索联想，证明动作可能已有局部效果；没有将失败录为成功、自动重放填写或假定搜索完成。旧控制入口丢弃服务端错误代码，故该次失败的具体原因尚不能确认，不能直接归因为平台提醒或请求拦截。
+- 控制入口现在仅透传严格受限的 ASCII 错误代码 `apiCode/api_code`，仍使用通用错误文字，不复制返回的 message/detail 或凭据。下一步可据安全代码诊断；已请求维护者示范一次普通搜索作为基线，后续按真实页面补适配。
+
+涉及文件：控制入口及其传输测试、README、整体方案、图解及本进度；没有改动浏览器执行器或重启当前会话。页面聚合包含隐藏提示和页脚，不据 DOM 中的文字认定平台已出现可见提醒；捕获上限和交互覆盖缺口已写入整体方案第 14.1 节。
+
+验证：隔离 `test-control` 单次通过，新增安全错误码透传、无效/含敏感片段代码过滤和失败不重放覆盖；文档与差异检查通过。未重跑上一轮后台/浏览器套件，没有成功平台候选、正式试跑或发布；未执行关注、私信、评论及回复。
+
+下一步：按整体方案第 14.1 节取得正常搜索基线，补失败阶段诊断、必要请求及可见交互适配，再固化搜索/详情/评论。当前会话保持，普通页面搜索示范结果尚待确认。
+
+提交/推送：未执行；保留已有工作区修改。
+
+## 2026-10-24-07：接续真实搜索与详情观察，补登录检测及精确请求实验策略
+
+目标：维护者完成普通搜索示范后继续有限学习；按用户要求先检测持久会话是否登录，再决定是否需要登录或账号确认。
+
+实际平台进展：
+
+- 取得维护者正常搜索“装修”的结果基线，并成功结构化读取一条可见结果的标题与同源来源。旧执行器的详情点击返回 `WRITE_REQUEST_BLOCKED`，当时没有请求摘要，不能追溯断定具体请求或将其称为平台提醒。
+- 同资料目录重开后，实际页面检测为 `logged_in`。用户明确确认使用当前账号后，恢复 ready 并采集；没有重新扫码。检测只依据可见导航/登录/验证状态，不读取 Cookie、存储或表单值，不替代当前账号身份核验。
+- 新执行器保存到普通填写、搜索回车和打开笔记的实际前后证据及精确阻断摘要。一次调用误把模板字面量当作填写值，随后按任务声明的 `parameter:keyword` 更正；失败未计成功，没有自动重放。被工具阻止检索时页面出现的“无结果”不能记成平台真实空结果。
+- 实验搜索 v1 放行已观察的检索请求后，实际出现装修笔记，但 APM 请求仍令回车失败；保留旧记录。补搜索 v2 后，实际参数化填写和搜索回车均成功，再采集动态加载结果，成功提取一条标题与来源；不是仅以 URL 或请求放行认定成功。
+- 笔记打开 v1 已进入同一结果的详情。实际视口文字及截图确认正文和 **1 条可见评论**，但 `/api/sns/v1/history/report_web` 请求仍被拒绝，点击继续登记失败，未重复点击或改写成功。页面显示的评论总数不作为已读取数量；没有展开回复、翻页或滚动读取更多评论。
+- 当前真实任务累计 **37 份观察、6 个分阶段成功步骤、0 候选、0 验证**。这些探索步骤包含先前阶段，不能直接当作从首页回放的完整链路。详情/评论容器尚未作为可读定位返回，未完成结构化评论字段映射。未执行关注、私信、评论发布或回复。
+
+工程完成：
+
+- 增加受限搜索回车，前后台与 v2 校验一致；仅已观察、唯一的普通搜索框按 `Enter`，评论/消息及 POST 表单不接受。后台提供“提交搜索（回车）”。
+- 明确点击产生的同源新页可接续，旧页关闭不误关已接续页面；人工确认前同源新页仍保持未就绪。等待确认期间曾发生 `POPUP_BLOCKED`，当时来源未证实；修正其阻断状态及显示，不能只提示登录确认。未知或出域页面仍关闭暂停，最多保存 10 条脱敏页面事件，不伪造请求。
+- 捕获优先实际视口、限制离屏候选并排除隐藏文本。失败保留实际 before/after、阶段、安全代码和截图，API 不插入成功步骤、不自动重放；后台刷新失败证据并保留表单，提供安全诊断查看。
+- 被动请求观察最多 30 条，失败阻断摘要按四字段去重最多 12 类，同时保留总次数，避免重复流量淹没必要请求。两层清洗不保存查询、正文、头或凭据，敏感路径泛化。
+- 增加搜索 v2、笔记打开 v1 实验策略，只让官网当前主框架中已核验的搜索框动作或固定格式笔记链接点击自然发出已观察精确请求。固定方法、来源、路径及资源类型，最长 15 秒、finally 撤销；没有通用 HTTP 调用，未知请求及其他动作仍受保护。策略版本/规则随摘要保存，API 按版本二次校验并兼容历史搜索 v1。
+- 登录检测区分已登录、未登录、需要验证和不确定。退出/验证会撤销 ready，恢复登录不自动恢复确认；不确定不等于未登录，也不撤销仍有效的当前确认。后台提示与按钮随状态变化。
+
+涉及范围：`tools/learning/` 的执行器、契约、检测与实验策略及测试，`apps/server/` 的动作边界/失败证据/状态与清洗，`apps/admin/` 的动作和状态界面，API/UI 验收脚本、根脚本及现有方案/图解/README。参考 A2A 工程保持只读。
+
+本轮验证与边界：
+
+- 后台全量 **42 passed，无跳过**，使用实际专用 PostgreSQL 测试库，浏览器行为仍为 FakeWorker；之后的小修定向验证：阻断状态 2 项通过，事件/错误传输/失败证据目标组 3 项通过、1 个 PG 参数分支跳过，最终策略版本清洗目标 1 项通过。阶段数不累加，也不把定向结果当作全量重跑。
+- 最终真实 Edge 本机工作进程回归 **26/26**，仅隔离合成页面，覆盖搜索回车、同源/未知窗口、确认前接续、失败留证和去重诊断、原会话/互斥/EOF 等。证据：[最终工作进程报告](../.tmp/worker-regression-uWhHzp/report.json)。
+- 合成 DOM 的登录检测 **13 个可见页面场景**及官方域/伪域边界通过；测试禁止读取 Cookie 和输入值。实验平台策略 **119 项纯函数边界断言**通过，包含请求规则、动作范围、唯一性、视口/遮挡、跨规则拒绝、过期及撤销；不发送真实平台请求。这些结果不能代替真实账号或完整业务验收。
+- PG + Edge 的完整 API/UI 端到端通过：7 步候选使用搜索回车及同源新页，失败保存 2 份实际证据且无成功步骤；界面实际使用搜索回车表单、登录检测提示及失败诊断。原变参/质量/重启流程仍通过，共 7 条验证，发布不放行，页面无脚本错误。证据：[端到端摘要](../.tmp/learning-acceptance-1792812246545/summary.json)。该次在后续小范围弹窗/平台策略补丁前完成；补丁后使用定向测试、最终 worker 回归及上述真实有限接续验证，没有再全量重跑端到端。
+- TypeScript 检查和生产构建通过；最后一处提示映射后再次类型检查通过。既有 TestClient 弃用及构建包体提示未阻断。本轮没有重跑 PG 迁移、检索扩展烟测、真实模型质量或 macOS。
+- 图解 8 页检查、文档链接与差异检查通过，报告和视口截图留在忽略目录。它们是本机验证资料，不随版本库分发。
+
+运行与未完成：更新后的服务与专用账号会话已恢复，当前保持实际详情页，API/后台使用 PostgreSQL；不代表永久在线。完整自动链路、评论字段与分页、独立正式模式试跑及任务后官方通知复查均未完成；没有判断账号权重或声称平台不会提醒，也没有正式发布或双端交付。
+
+下一步：按整体方案第 14.1 节处理新发现的辅助请求及详情/评论可读容器，补有限字段/等待/结束条件；再单独录制正常起始链路、冻结候选和变参验证。保留本次探索与所有失败事实。
+
+提交/推送：未执行；保留共享工作区此前所有未提交修改。
+
+## 2026-10-24-08：完成首个有界图文候选与真实变参探索回放
+
+目标：接续维护者确认的账号，补齐搜索、详情和评论读取适配，录制干净链路并用不同关键词与笔记验证。
+
+实际平台进展：
+
+- 原任务继续保留分阶段探索及失败；新建独立录制任务 `learn_df3d819892ac481c838a186a6627a8c1`，输入为 `keyword` 和 `note_title`，没有将旧混合步骤直接冻结。重开同一持久资料实际检测为已登录，沿用用户本会话已明确确认的账号，无需再次扫码。
+- 成功录制 8 步：填写关键词、搜索回车、等待结果、按标题唯一选笔记、等待详情、提取标题/正文/作者、右侧有界条件滚动、提取首层完整可见评论。搜索排序变化后仍以标题核对目标；第二组结果带平台 AI 摘要，实际读取的是选中笔记详情。
+- 冻结候选 `candidate_b13f6407b722422abb86ddbc4d128f9b`，摘要前缀 `8a3d3984c073`，静态校验通过。“装修”和“一切从简”两组不同关键词/笔记的完整探索回放通过，各返回 1 篇正确正文及 1 条完整可见首层评论，按预先观察到的文本片段固定比较，分别保留 9 份试跑证据。输出明确保留 `truncated=true`、覆盖范围和裁剪行计数；没有把页面评论总数当作已读数量。
+- 第一轮变参回放在填写搜索时被工具阻止，实际证据显示同一 APM 路径使用 XHR，而旧搜索策略仅接受 fetch。该失败及空输出保留，未改记成功；仅在搜索 v3 增加精确 XHR 规则后重新验证通过。工具拦截不等于平台官方提醒，未核验账号权重或任务后通知。
+- 搜索 v3 加载后两组均重新完成回放：变参约 70.5 秒，原参数约 72.5 秒。最终录制任务有 **50 份观察、8 个步骤、1 个候选、5 条验证**：1 条静态通过，4 条探索试跑中 3 条通过、1 条旧失败保留。候选摘要仍与冻结时一致；不同参数仅作为试跑覆盖值，没有改写候选。证据摘要：[本机试点汇总](../.tmp/xhs-final-pilot-summary.json)。
+- 当前试点最多滚动 3 次、每次 320 像素，完整评论行出现即停，最多提取 3 条完整可见行。长正文样本初始没有可见评论，实际滚动 1 次命中；首条已完整可见时可 0 次。未展开回复或读取后续批次，没有执行关注、私信、评论发布或回复。
+
+工程完成：
+
+- 详情打开策略 v2 补实际观察到的浏览历史请求；普通读/提取/等待/滚动采用独立辅助流量策略，不能借用搜索或详情业务请求。搜索 v3、详情 v2、读取辅助 v1 分别限定 7/8/2 个精确方法、来源、路径与资源类型，仍是最长 15 秒的当前主框架动作窗口；历史策略按旧范围清洗。
+- 页面观察增加实际可读 ID、语义区域、滚动容器和可追溯集合，返回相对字段提示；集合从真实 DOM 和最多 12 层安全祖先推导。保留输入/按钮配额，避免密集链接挤掉搜索框；固定语义核对允许轮换占位示例，真正的语义变化或当前定位缺失分别停止。先前 `STALE_TARGET` 的具体单一原因没有追溯证据，不直接归因于占位文字。
+- 增加 `scroll.until_selector` 与 `extract.complete_only`，贯通 worker、Python 契约/校验和后台表单。完整行模式先校验真实缺失、隐藏、敏感与多匹配错误，再跳过裁剪行；额外保存 `skipped_incomplete_count`，空结果不能通过内容断言。省略新选项保持旧合同，边界/预算结束只作有界条件轮询，不追加滚动或自动重放。
+- 后台准确展示弹窗/范围阻断，不再将这些状态当作普通登录待确认。涉及 `tools/learning/` 执行器/契约/策略及测试、`apps/server/` 清洗和动作合同/测试、`apps/admin/` 表单/状态提示、API/UI 验收脚本及现有文档图解。A2A 参考工程保持只读，未新增检索或桌面运行实现。
+
+验证与阶段边界：
+
+- 本机 Edge 工作进程最终 **32/32**，覆盖固定搜索语义及配额、条件滚动 0 次/命中/边界/预算/懒加载、完整行过滤及后置字段错误；仅使用隔离合成页面。报告：[worker 回归](../.tmp/worker-regression-Om8Jr4/report.json)。该报告在最后搜索 v3 的精确类型补丁前完成；补丁后纯策略 **210 项断言**通过，详情/读取策略对新 XHR 类型仍拒绝，未重复全量 worker 回归。
+- 新滚动/提取合同定向 **3 passed、47 deselected、无跳过**，搜索 v3 元数据定向 **2 passed、50 deselected、无跳过**；均包含 SQLite 及实际专用 PostgreSQL 测试库，浏览器行为为 FakeWorker。后台全量未在本条重跑，不能将这些目标数累加成全量结果。
+- PG + Edge 的完整 API/UI 端到端通过，新增的条件滚动、完整可见行和动作字段隔离表单均实际提交；旧搜索回车、失败留证、变参、质量反馈和重启恢复仍通过，保留 7 条验证、`errors=[]`、发布不放行。报告：[最终端到端摘要](../.tmp/learning-acceptance-1792816035113/summary.json)。该次在搜索 v3 补丁前完成，之后用上述定向验证及真实样本回放验证策略修订。
+- 前端类型检查、生产构建通过，已有包体及 TestClient 弃用提示未阻断；离线图解 8 页无脚本错误或几何问题，本地文档 33 个链接及差异检查通过。证据在忽略的本机目录，不随仓库分发。PG 迁移、检索扩展、真实模型质量和 macOS 未执行。
+
+未完成：当前仅探索模式通过；正式模式的通知/功能基线、完整过程复查和任务后反馈尚未采集，独立身份/来源读回未接入，没有正式发布或商家双端交付。后续按整体方案第 14.1 节验证正式质量及补充边界，再推进第 14.2 节的商品条件和需求判断。
+
+结束检查：发布预检明确不放行，已通过结构/两组参数/Windows/证据检查，macOS、独立来源读回及正式质量仍不满足。当前维护服务前端首页、API 及前端代理 health 均返回 200，数据库为 PostgreSQL，专用浏览器保持原样本详情；服务生命周期仍依赖本机开发进程，不代表永久在线。
+
+提交/推送：未执行；保留共享工作区已有修改。当前候选与平台证据保存在本机独立学习账本及忽略的资料目录中。
+
+## 2026-10-24-09：正式执行修订与评论分批、明确空态合同
+
+目标：维护者报告运行前状态正常并授权 Codex 自行执行正式模式、继续开发读取边界；任务后的账号检查仍由维护者提供实际反馈。
+
+真实平台执行：
+
+- 以维护者本轮“正常”回复记录人工运行前通知/功能基线，没有假称执行器独立核验官方消息。旧候选 `candidate_b13f6407b722422abb86ddbc4d128f9b` 首次正式试跑约 49.4 秒后等待超时：真实搜索结果首张卡没有标题，固定首卡标题定位未出现；没有阻止请求。失败验证、5 份证据与过程复查不通过记录保留，旧候选为 `review_required`。
+- 新增集合可见数量等待以解除对首张卡标题的依赖。分批准备样本实际按平铺行读到 4 个不同评论 ID，其中含已展示回复；依据实际父容器结构进一步限定首层，核对得到 3 条首层并排除该回复。准备任务保留，不将其混合步骤当作最终候选。
+- 在独立任务 `learn_a1ff98e8618c43aeafab61772bcce2f6` 录制 7 步：填写、回车、集合等待、精确标题点击、详情等待、正文提取、首层分批提取。冻结候选 `candidate_d2de3f860c4d48839ff01881d9a62ac3`，摘要前缀 `c7ca1b76f572`；静态校验及两组不同关键词/笔记的正式模式执行通过，约 72.2/83.0 秒，各保留 11 份执行证据。
+- 两组各读 3 批，分别输出 3/4 条去重首层评论，去掉 1/2 次重复观察；分别以批数/时间预算结束，保持 `truncated:true`。当前样本每次滚动 320 像素、最多 3 批（含首批）、输出上限 5，不声称读完页面显示的全部评论，也未展开回复。核对搜索、对象/来源、输出、逐批依据及关键截图后，两条正式验证均追加“过程复查通过、等待账号反馈”。
+- 最终新任务 **42 份观察、7 步、1 个候选、3 条验证**（静态 1、正式执行 2，均通过），候选摘要未变化。质量仍为 `awaiting_observation`；观察窗口分别到北京时间 **2026-10-24 15:17:30、15:18:56**。告知维护者 15:20 后核对官方消息及搜索/详情/评论功能，再由 Codex 代登记实际结果；没有提前登记 `clear`，没有安排无人值守检查。汇总：[本机正式执行摘要](../.tmp/xhs-runtime-final-summary.json)。
+
+工程实现：
+
+- `wait.min_count` 仅显式可见等待使用，默认保留唯一对象语义；录制/冻结检查实际集合来源，回放允许从零项延迟加载开始，逐次核对安全和范围。搜索、详情和读取请求策略均未扩展。
+- `extract.row_selector` 将行限定在已观察的唯一普通容器内；`batch` 先读首批后有界滚动，强制完整行、安全必填业务 ID 去重及同来源/根对象，最多 5 批、每次最多 1600 像素，批次预算 15 秒。每批真实截图保存到 `batch_evidence_ids` 并参与候选摘要；来源替换、同 ID 内容冲突、未知请求等失败保留已有批次、不插成功步骤。少量行无溢出的普通滚动容器可首批读完后报告边界；零新增不等于完整读完。
+- 明确空态要求 `allow_empty`、相对行定位及精确空态依据，在普通唯一容器、零行、完整可见、非忙碌和可用会话下再次核对；仅 `{"state":"empty"}` 预期可通过，普通文本预期继续拒绝空内容。字段真实缺失、裁剪、未加载或退出登录不能伪装为空。DTO 归一空态文字首尾空白后冻结，旧候选和原有省略参数的合同保留。
+- 后台增加“正式模式试跑”直达入口、观察到期时间/账号复查说明、集合数量等待与批次/空态表单；选项互斥并按动作隔离，原配置测试保留探索默认。回放保存受限 `error_codes`，登录检测发现退出/验证时撤销 ready，批次在下一状态核对停止。
+- 涉及 `tools/learning/` 执行器、JS 合同及浏览器测试，`apps/server/` 合同/比较/证据冻结/错误清洗及测试，`apps/admin/` 类型、表单、候选入口和质量提示，隔离验收夹具与现有文档图解。参考 A2A 保持只读，没有开发桌面、模型或召回服务。
+
+验证与边界：
+
+- 后台全量 **61 passed、无跳过**，约 148.7 秒，包含 SQLite/实际专用 PostgreSQL；之后仅空态文本归一小修，受影响目标 **2 passed、59 deselected、无跳过**。不与此前 42 项或中间定向次数相加。
+- 最终隔离 Edge worker **40/40**，覆盖逐批证据/去重/边界/同高度懒加载/冲突或来源变化失败、明确空态、从零项加载的集合等待及原会话/EOF 等。报告：[工作进程回归](../.tmp/worker-regression-N1TIsP/report.json)。登录检测单独 **13 个合成 DOM 场景**和官方 URL facade/伪域边界通过，禁止读取 Cookie 和输入值；源码核对批次前后检测失效即停止。没有主动登出真实账号或构造完整官方会话失效测试。
+- 完整 PG + Edge API/UI 单轮验收通过：6 项新增界面断言及旧回归通过，实际保留 **9 条验证**，`errors=[]`，发布不放行。报告：[最终端到端摘要](../.tmp/learning-acceptance-1792822016814/summary.json)。首轮新增空态夹具漏做静态校验而正确被拒，补前置后独立完整重跑通过，没有拼接阶段结果。报告使用最终查询计数；随后仅将控制台旧计数也改为同一查询变量并做语法检查，未重复整套。
+- TypeScript 检查和生产构建通过；离线图解 8 页无脚本/几何问题，本地文档 36 个链接及差异检查通过。现有 TestClient、组件弃用和包体提示未阻断。报告及平台资料均在忽略的本机目录。真实平台搜索/评论空态、登录失效与验证页尚未学到，不能用合成用例代替；PG 迁移、检索烟测、模型质量、macOS 未执行。
+
+结束状态：维护服务健康，前端首页 200、API 为 PostgreSQL，专用浏览器保留第二组详情。发布预检仍不放行，缺账号后续反馈、独立来源读回和 macOS 验证；没有关注、私信、发布评论、账号权重判断或正式分发。后续按整体方案第 14.1–14.2 节推进。
+
+提交/推送：未执行；保留共享工作区原有改动，所有旧探索、失败、候选及验证历史均保留。
+
+## 2026-10-24-10：登记观察窗口内的人工反馈
+
+目标：将维护者“目前看都正常”的实际反馈追加到对应正式验证，同时保留时间与来源边界。
+
+完成情况：核对 UTC 时钟，登记时为北京时间约 14:35，早于两条正式验证的 15:17:30、15:18:56 到期时间。分别追加 `waiting` 人工反馈，沿用此前过程复查通过；读回新候选仍为 `awaiting_observation`、摘要不变，发布预检及 `published` 均为 false。没有将当前正常视为观察窗口已完成，也未改写原验证或旧候选失败。证据：[中途反馈摘要](../.tmp/xhs-midwindow-feedback.json)。
+
+本轮仅通过本机 API 追加 2 条质量记录并读回状态，没有业务代码修改、真实浏览器操作或重新运行测试套件。维护者另确认下一阶段样例为装修服务寻找有装修需求的业主；确定范围与实施顺序补充到整体方案第 14.2 节，业务能力和模型尚未实现。进度记录仅覆盖实际账本更新与已确认范围，不记录一般问答。
+
+未完成：窗口到期后的官方消息/功能实查反馈；后续按整体方案第 14.2 节推进业务闭环。提交/推送均未执行，保留共享工作区已有修改。
+
+## 2026-10-24-11：装修搜索结果与规则初筛，修复来源脱敏和表情截断保存
+
+目标：接续已确认的“装修服务，寻找有装修需求的业主”，先把真实搜索结果结构化读取并保留少量待读笔记。地区尚未提供，留空；模型、真实需求判断与详情自动衔接分开验收。
+
+工程完成：
+
+- 新增独立四步搜索读取合同：填写 `keyword`、搜索回车、等待至少一个可见标题、提取 `search_results`。根据实际观察选择唯一普通根容器及有标题的卡片行，不读取搜索页 AI 摘要；标题/作者可选、同源链接必填，完整行模式跳过视口裁剪行，保留有界及截断标记。
+- 增加严格 `{"state":"nonempty"}` 结构预期，仅合法提取输出、正条数、字段/必填/来源及批次元数据一致才通过；不等于语义或采购意图验证。零结果、仅裁剪行、错误形状或 `read` 输出不通过该断言。
+- 后台新增“内容初筛”页面及鉴权 API，按当前装修样例规则保留最多 1–3 篇。保留求助信号和相关案例；地区仅保存，业主身份、真实需求及预算均未核实。接口拒绝不支持的服务/客户条件，不把装修规则套到其他业务。
+- 按同站标准笔记 ID 归并，缺标题、脱敏或重复/冲突标题不自动选；合法来源但缺可用标题显示“信息不足”，无效来源另行区分。超过保留上限写明未选理由，直接否定完工/入住等表述不冒称已完成。规则模式、条件、摘要、验证、证据、理由和已识别失败均可回看。
+- `discovery_runs` 作为追加事实接入 SQLite/PG schema 5；旧记录不随规则变更重算。迁移脚本兼容旧 SQLite 尚无初筛表，并保留非空目标拒绝、备份、固定插入顺序和事务回滚。受限控制入口增加 `discovery.list/get/create`，沿用本机鉴权、CSRF、ID 限制和失败不重放。
+- 修复公开来源编号误脱敏：仅官网无凭据、标准端口、精确标准笔记路径保留公共 24 位十六进制编号；查询、片段、其他 URL 和文本仍按原规则脱敏，没有放宽请求策略或增加通用浏览器接口。
+- 修复长页面截断表情导致 PostgreSQL UTF-8 编码异常：浏览器返回入口递归处理无效 UTF-16 片段，观察保存覆盖失败捕获旁路；合法 Unicode、JSON 序列化规则、候选摘要和历史数据不变。
+
+实际平台与失败事实：
+
+- 新任务 `learn_fc248254100b482c9ae2508d9648f29d`，冻结搜索候选 `candidate_64ba8e4187f546c5a228ce9325c16b5c`，摘要前缀 `919454f3bf02`，静态通过。重启后同资料仍检测为已登录，沿用维护者已确认的账号，不再扫码。
+- “准备装修”探索约 **27.8 秒**，读取 3 条完整可见结果、跳过 2 次裁剪行，按标题规则保留 2 篇进一步阅读；保存 5 份验证证据。保留原因是准备装修表述，不确认作者为业主或真实客户。
+- “装修案例”首次探索约 **29.0 秒**，读取 3 条、跳过 3 次裁剪行，未保留笔记。其中 1 条公共编号被旧通用手机号脱敏误伤，导致业务来源校验不通过；旧结果保留。其余标题缺装修词也未选中，说明标题规则存在漏筛，不能解释为平台没有相关内容或客户。
+- 加载来源修复后的首次追加执行出现 **HTTP 500 / UnicodeEncodeError**：长文本的表情代理对被截断，保存观察时数据库拒绝；原 20 份观察增加到 23 份，但没有生成本次完整验证或初筛记录。没有自动重放、伪造完整失败验证或改记成功；工程事实见 [保存异常记录](../.tmp/xhs-discovery-unicode-incident.json)。
+- Unicode 修复后另起一次“装修案例”探索，约 **27.7 秒**通过，读取 3 条、3 个有效来源，编号无误掩，仍因标题规则未保留。新记录另存，原两条初筛及候选摘要逐字读回不变；每次均为 `coverage:bounded`、`truncated:true`，没有把上限 10 或页面总数当作实际读取量。
+- 最终新任务 **28 份观察、4 步、1 个候选、4 条验证**（静态 1、探索 3），形成 **3 条初筛记录**；另有上述未生成完整记录的持久化失败，未混入通过数。汇总：[本机初筛摘要](../.tmp/xhs-discovery-final-summary.json)。尚未自动进入选中笔记的详情/评论，没有调用模型。
+
+验证与边界：
+
+- Unicode 修复后最终后台完整 **70 passed、无跳过**，约 **186.4 秒**，包含 SQLite 和专用 PostgreSQL。覆盖装修范围、否定表述、未选上限理由、来源/标题区分，以及 30k 截断表情、嵌套文字、成功/失败证据、API 读回及旧摘要不变。修复前 67 项全量及新增 3 项定向均为阶段结果，不与最终 70 项相加；只有既有 TestClient 弃用提示。
+- 最终 worker 单轮 **43/43**：新增 1 组纯 URL 正反例与原 42 组隔离 Edge 流程，包含严格非空结构预期。报告：[工作进程回归](../.tmp/worker-regression-fFs9GY/report.json)。恶意/伪域、HTTP、凭据、非标准端口、账号及非标准笔记路径均不享受编号例外；普通手机号和敏感查询仍脱敏。不是 43 个真实平台样本，不与此前 40/42 次相加。
+- 新页面完整 PG + Edge 隔离 API/UI 单轮通过：8 条合成结果保留求助及同行各 1 篇，来源/标题不足不选，条件、理由、证据、历史重开、重启保存及缺会话失败通过；2 条初筛历史、`received_writes=0`、`errors=[]`。报告：[内容初筛验收](../.tmp/discovery-acceptance-1792825185336/summary.json)。此前两次因新夹具 schema 名及零高度空链接失败，修夹具后独立完整重跑，没有放宽执行合同。该套在最后来源/Unicode 修复前通过，之后用对应定向、worker 与真实平台重跑验证，没有重复整套 UI。
+- 迁移隔离回归 **9/9**，仅专用测试 PG 随机 schema，含初筛数据/Unicode/顺序、旧库缺表兼容、非空目标拒绝及外键失败全表回滚；没有执行开发数据迁移。报告：[迁移回归](../.tmp/migration-regression-n4og18yw/report.json)。

+## 2026-10-24-12：初筛到单篇正文与首层评论衔接，增加对象绑定和阅读历史
+
+目标：把初筛实际保留的笔记接入已学详情链路，逐篇保存来源、正文、有限评论、验证及失败原因；本轮不接模型或判定真实需求。
+
+工程完成：
+
+- 新增单篇阅读 API 与 `reading_runs` 追加事实，SQLite/PG schema 6。客户端仅提供详情候选及该初筛已保留的笔记编号，关键词、标题与来源由后台取不可变初筛记录；非保留对象、额外标题/URL 或跨归属输入不执行。候选须符合已学七步业务字段、同平台/站点及静态验证，使用其已确认会话，不自动开关浏览器或重放失败。
+- 复用原七步候选而不改写：正常搜索、唯一标题点击、等待详情、读取 `title/body/author`、有界分批首层评论。验证可选 `note_binding:{note_id}` 仅适用该合同；点击前核对当前真实链接 ID，落页后及后续等待/提取/批次内持续核对页面 ID。对象或标题变化即停，已有实际证据保留。
+- 绑定记录含目标 ID、链接检查、页面检查、实际来源及实际正文标题；后台再次比较对象、标题和两提取来源并保存 `note_source_binding` 断言。绑定输出使用实际 origin + pathname，不带 query/hash；旧无绑定语义、请求策略、冻结摘要和历史不变。这是同一浏览器内的对象核对，不等于独立身份的业务读回。
+- 阅读分为完成、部分完成与失败。只有对象核对通过的正文才作为本篇内容展示；评论缺字段或未读到完整行时可保留正文，不把 0 条当作平台确认空态。范围以实际条数、批次、去重、结束原因和截断标记展示。
+- 内容初筛页面可选同站详情候选、逐篇触发阅读，查看绑定、正文、评论、验证、证据和历史；回看地址为 `#/discovery/{run_id}?reading={reading_id}`，刷新及前后退保留对象，错初筛/过期 ID 不展示错归属结果。目标编号标签明确为“绑定目标笔记标识”，不把前置失败时的预期编号冒称实读编号。
+- 受限控制入口增加 `readings.list/get/create`；新增隔离 `test-reading` 脚本。迁移兼容旧 SQLite 没有阅读表，保证新阅读数据在初筛/候选/验证之后复制，保持非空目标拒绝、备份与整体回滚。
+
+真实平台与边界：
+
+- 加载冻结代码后，同资料目录仍检测为已登录；沿用维护者此前明确确认的账号。重新搜索“准备装修”约 **29.6 秒**，读取 3 条完整可见结果并保留 2 篇，新增初筛 `discovery_8dd08f13fc6a47c48c8385e2665540e7`，服务地区继续为空。关闭搜索任务会话，重开同账号的详情任务仍已登录，无需扫码。
+- 第一篇阅读 `reading_d887f5884bb1481fa02b5676c3d4dd9e`，探索约 **85.3 秒**通过：实际得到 1 篇正文和 **5 条去重首层评论**，读 3 批、去掉 2 次重复观察，达到本轮条数上限结束，`truncated:true`，保存 **11 份证据**。点击前链接 ID、点击后页面 ID、正文标题及两输出来源均核对通过；不是读取全部评论，也未展开回复。
+- 第二篇阅读 `reading_9fa8e3a65ba84596a0acb70658bb8bde`，探索约 **32.4 秒**失败：重新搜索后目标已不在当前视口，`TARGET_NOT_IN_VIEWPORT` 在点击前停止；未完成来源绑定检查，也未读该笔记正文/评论，保存 **6 份实际证据**及失败验证。没有盲目滚动、换一个对象、直跳来源或自动重试，没有把未执行的阅读改记成功。
+- 同一初筛下形成 2 条独立阅读记录（完成 1、失败 1）。详情任务当前 **59 份观察、7 步、1 个候选、5 条验证**：原静态 1、正式执行 2，新增探索阅读 2（通过 1、失败 1）。原 3 条验证、原初筛记录及候选摘要逐字读回不变；候选质量仍为 `awaiting_observation`，`published:false`。本轮没有收到到期后的官方消息/功能人工反馈，不以窗口已过或首篇通过自动清除质量待办。
+- 汇总：[本机阅读衔接摘要](../.tmp/xhs-reading-final-summary.json)。所有真实资料保存在本机学习账本与忽略目录中，未写入模型；没有关注、私信或发布评论动作。
+
+验证与边界：
+
+- 新后台阅读目标 **5 passed、70 deselected、无跳过**，约 79.7 秒，包含 SQLite 与实际专用 PostgreSQL。覆盖来源/标题/proof、仅保留对象可读、部分正文、会话失败、owner、不可变历史和 public Verify 大写编号归一。
+- 75 项全量首轮 **74 passed、1 failed、无跳过**，约 296.5 秒。唯一失败是旧初筛不可变测试使用 `TRUNCATE discovery_runs`：新增阅读外键使 PG 在不可变 trigger 前先拒绝，未命中旧测试预期异常。仅将测试改为 `TRUNCATE discovery_runs CASCADE`，与原事实保护测试一致，产品代码未改；受影响 PG 目标随后 **1 passed、74 deselected、无跳过**，约 11.6 秒。未重跑整套，不能称为单轮 75 项全过，也不与上轮 70 相加。
+- 最终隔离 worker **48/48**，为原 43 组与新增 5 组绑定流程的同一轮报告：[worker 回归](../.tmp/worker-regression-Da61Sg/report.json)。覆盖正确对象、同标题错 ID 点击前拒绝、跳转后 ID 变化、正文标题变化、批次内来源漂移、phone 样公共编号和旧无绑定路径。随后仅补含敏感 query/hash 的合成夹具，真实 Edge 完整七步目标 **1 项通过**：[来源边界目标](../.tmp/binding-query-hash-eSInmP/report.json)。产品未再变化，未重跑旧 43 组；不是 49 项全量或平台样本。
+- 新 PG + Edge 完整 API/UI 隔离验收单轮通过，保留 **4 条阅读记录**（完成 1、部分完成 1、失败 2）。两篇对象、正文保留、首层 3 条/2 批、绑定、证据、hash 刷新与前后退、错归属/过期 ID、历史、重启及未就绪不自动登录均通过；同标题错来源的实际 DOM 点击 **0**、错页正文请求 **0**，`received_writes=0`、`errors=[]`。报告：[阅读页面验收](../.tmp/reading-acceptance-1792827229128/summary.json)。之后只修改上述目标编号标签并再次类型检查，没有重复完整 UI 验收。
+- 迁移隔离回归 **13/13**，仅专用测试 PG、13 个随机 schema 均清理；新阅读数据、Unicode/顺序/可空引用、旧库缺表、非空目标、外键失败回滚和原核心表缺失拒绝均通过。报告：[迁移回归](../.tmp/migration-regression-4ef9osr1/report.json)。没有执行开发数据迁移。
+- TypeScript 检查与生产构建通过，最后纯标签修改后类型检查通过；受限控制传输、语法、49 个本地文档链接与差异检查通过。离线图解 8 页无脚本或几何问题，报告：[图解检查](../.tmp/plan-qa/checks.json)。既有 TestClient/组件弃用及包体提示未阻断。未重跑检索扩展、macOS、模型判断/费用或旧详情的正式模式；只读探索不代替正式发布与商家交付。
+
+涉及文件：新增 `apps/server/reading.py`、阅读测试及 `scripts/test-reading.mjs`；学习验证/DTO/SQLite/PG、worker 与测试、内容初筛页/路由/类型、迁移脚本与测试、受限控制入口和现有 README/整体方案/图解/本进度。原 A2A 工程未改，保留共享工作区全部原有修改。
+
+未完成与下一步：真实第二篇暴露重新搜索后的视口缺口，已将“选定对象重排后的有界定位与进入视口”列为整体方案第 14.2 节当前优先项；修订候选和变参验证通过后再扩大逐篇范围及接模型。当前入口和安全中断已实现，不能宣称所有保留笔记均可稳定阅读。真实空态、登录失效、回复层级、独立读回、后续账号反馈、模型与双端发布仍未完成。
+
+结束检查：已加载更新代码，API/前端代理 health 正常、前端首页 200，使用 PostgreSQL；专用浏览器保留第二次失败后的实际搜索页，没有自动续跑。服务仍依赖本机开发进程，不代表永久在线。
+
+提交/推送：未执行。测试报告及平台证据属于忽略的本机资料，不随版本库分发。
+
+## 2026-10-24-13：有界目标定位八步修订、硬截止与部分结果留存
+
+目标：补原第二篇在搜索结果重排后离屏的定位缺口，保留旧七步及失败，另录修订版并实际变参验证。
+
+工程完成：
+
+- `scroll.until_target` 限定最新观察的唯一普通纵向容器，目标匹配使用固定容器后代、明确参数与同一点击 CSS；方向、距离、次数和时间有界，目标已完整可操作时零滚动。重复、遮挡、编号/来源/根变化或预算用尽即停，互斥旧 `until_selector`。录制留参数与真实证据，旧 body 滚动及七步合同不改。
+- 新八步为填写、回车、集合等待、容器目标定位、点击、详情等待、正文、首层评论。来源绑定在定位、点击及读取中核验；`seek_results` 保存步位、实际次数/逐次位置高度、是否找到及原因，只表示定位阶段，不替代来源或整次阅读成功。后台表单、候选筛选和阅读回看已接，修复候选选择框在嵌套 grid 中持续撑宽页面的问题。
+- 首次回放暴露原总预算只在步骤之间检查，单步和失败取证可能跨过 120 秒 RPC。已补整段硬截止，旧总额 90 秒、新八步绑定为 90 秒加已声明定位预算（最多 105 秒），总额内预留 2 秒关闭与返回，不增加 RPC 上限。到期撤销执行状态、关闭本次上下文，返回已完成输出、真实步骤/批次图及定位记录；活动定位记时间到期，已完成定位保持成功。确认关闭才返回 `session_closed:true`，后台据此清缓存并暂停，部分验证正常保存，资料目录保留，不自动重开或重放。
+- 返回定位数组及逐次数字对象作值复制，避免迟到回调改写已返回事实；没有改冻结步骤或摘要。没有新增数据库表或迁移。
+
+实际平台与历史：
+
+- 重开同资料仍检测为已登录，沿用维护者已确认账号。首个新录制任务 `learn_5cf43a7e7e774342a454826df7a8d0b8` 在实际结果容器滚动 **1 次 / 320 像素**，进入原第二篇正确编号并取得正文；评论遇纯图片而触发 `REQUIRED_FIELD_MISSING`。保留 **7 个成功步骤、20 份观察及失败批次证据，未生成完整候选**。首次集合等待还因最新观察尚无结果定位被 422 拒绝，采集就绪页面后才继续，没有把前置拒绝记为成功。证据：[不完整录制及真实失败](../.tmp/xhs-seek-recording-failure.json)。
+- 图片评论没有可读文字，现有 `required body` 合同不做 OCR；完整行模式只跳过裁剪，不能跳过真实缺文字。未改作者/整行充正文，也未放宽必填来通过。另起文本样本任务 `learn_1134872f004e45f0b9c5307aa7df948a` 录完 8 步，定位 **0 次**，录制得到 3 条评论、2 批、时间预算结束；冻结 `candidate_f4c5b121840b426a89cbb72522412817`，摘要前缀 `bd0d349bb1f5`，静态通过。
+- 硬截止修复前，首次新候选回放第二篇触发 `worker_timeout`；阅读 `reading_ec87f0663dc546eaac04a119ee164b8c` 保存失败，**没有完整验证、输出或返回证据**。上下文关闭，未自动重试；不能据无记录断言页面无动作。原事实保留：[RPC 超时阅读](../.tmp/xhs-seek-rpc-timeout-reading.json)。
+- 硬截止修复后、最后纯返回深拷贝前，首篇探索 `reading_7a382eeb82e7495798ecb86fdf35a8f1` / `validation_b3b0f1e817394a838e06befaf1951af4` 约 **80.6 秒完成**：定位 0 次，1 篇正文、**5 条去重首层评论**，3 批、去重 3 次、条数上限结束，12 份证据；链接、页面编号、正文标题与输出来源通过，仍为截断的有限范围。
+- 加载最后深拷贝修订后，第二篇探索 `reading_58d5fe09137c4bab8c939e9c86e323b0` / `validation_5e51b75e0854403e8a7d1411918deacd` 约 **100.3 秒（含后台保存）部分完成**：实际 1 次滚动，从 0 到 320；来源核对及 41 字正文已得，评论阶段 `VERIFY_BUDGET`，无可用评论输出。保留 8 份真实证据和失败验证，定位摘要仍为已找到，确认浏览器关闭，任务 paused / ready false。不能将此回放说成评论已成功，纯图片缺口依据上项录制另报。
+- 同初筛现在共 **5 条阅读历史**：原完成/离屏失败、新无完整结果超时、新完成及新部分完成均保留。读回原初筛、原两条阅读、旧七步清单/摘要及新八步冻结清单/摘要不变。新任务 42 份观察、8 步、1 候选、3 验证（静态及两次有完整结果的探索）；另有上述无完整验证超时。汇总：[实际平台最终摘要](../.tmp/xhs-seek-final-summary.json)。新候选为 experimental、未发布，旧正式候选仍等待窗口后的真实账号反馈，没有据时间经过代填无异常。
+
+验证及边界：
+
+- 最终后台完整 **82 passed、无跳过**，约 **340.8 秒**，覆盖 SQLite 和实际专用测试 PostgreSQL。包含有界合同/证据/7–8 步兼容、摘要预算核对、部分内容与实际关闭、清就绪、下次不续跑及历史不变。前 80 项为闭会话修复前阶段，不与定向次数累加。日志：[82 项最终输出](../.tmp/test-server-session-closed-82.log)，只有既有 TestClient 弃用提示。
+- 硬截止版完整隔离 Edge **57/57**，含旧 48、有界定位 6 及预算 3 组；报告：[完整浏览器回归](../.tmp/worker-regression-tdVx6A/report.json)。最后仅返回深拷贝修订后，受影响预算 **3/3**，含不可变断言和 4 个实际 Edge 中断场景（等待、字体截图、DOM 阻塞、正文/首批后评论截图），已有真实 PNG/正文保留、无迟到成功、资料可重开。报告：[最后预算目标](../.tmp/worker-regression-tk3yd6/report.json)。没有称最后修订后又完整跑 57 项，也不相加成 60。
+- 硬截止修复后的完整 **PG + Edge API/UI** 通过：表单零滚动录制、重排后 3 次实际滚动并完成正文与有限首层评论；滚动预算/目标消失/重复均停止，失败点击和正文请求为 0；旧七步可选且不暗加定位、摘要/105 秒预算、历史/hash/刷新/重启通过。最终保存 4 条合成阅读（完成 1、失败 3），`received_writes=0`、`errors=[]`。候选框连续 5 次宽度稳定、页面无横向溢出。报告：[最终界面验收](../.tmp/reading-seek-acceptance-1792831062508/summary.json)。此前两轮布局失败与修复前通过报告保留；最后深拷贝后未重复完整 UI，使用上述受影响目标验证。
+- 最终 UI 类型检查及生产构建通过，只有既有包体提示；随后仅验收脚本加几何断言与 worker/API 修复，UI 无再变更。语法、本地文档链接及差异检查通过；图解 8 页无脚本或几何问题，报告：[图解检查](../.tmp/plan-qa/checks.json)。本轮未改 schema，未重跑迁移或检索扩展；没有 macOS、模型、正式模式新样本、商家发布或写操作验收。
+
+涉及范围：worker/动作合同与回归、后端学习/阅读契约及测试（含 `test_budget_closed.py`）、动作表单/内容初筛/类型、新 `scripts/test-reading-seek.mjs` 及命令入口，现有 README、整体方案、图解和本进度。原 A2A 工程未改，共享工作区已有改动保留。
+
+未完成与下一步：按整体方案第 14.2 节补阶段耗时与读取/取证成本、媒体评论类型和新候选验证，再接模型需求判断。定位已能到达该对象，不代表第二篇评论已完成；真实空态、登录失效、更多范围、独立读回、账号后续反馈、双端与正式交付仍未完成。
+
+结束检查：API/前端代理 health 正常，前端首页 200，PostgreSQL；最后专用浏览器已按预算关闭，任务保持暂停，未自动继续。服务依赖本机开发进程，不代表永久在线。提交/推送均未执行；报告、平台证据和资料目录属于忽略的本机资产，不随版本库分发。
+
+## 2026-10-24-14：显式媒体评论、阶段耗时与限定目标检查，真实两篇完成
+
+目标：补纯图片评论的显式内容合同，定位读取/取证成本，并在已有预算和对象核对下验证新的有限范围；不改写旧文字候选或失败。
+
+工程完成：
+
+- 新字段 `source:"content"` 保持 `required:true`，配置内容根及其相对文字、媒体 CSS，媒体上限 1–4。输出 `body:{kind,text,media,media_truncated}`，明确区分 `text / media / mixed`；无文字为 `null`，媒体只保存类型及相对定位。只认实际加载、可见的正文图像/视频，排除头像和链接媒体，不返回原媒体 URL、替代文字、文件或 OCR 结果。无真实内容、加载失败、敏感或歧义仍失败；原文字必填、完整行和来源绑定语义不变。
+- 安全 `read_hints` 提供实际媒体定位、类型和加载状态，不提供媒体地址。媒体证据复用真实批次截图，页面明确标为未解释；不能把媒体存在推断成无需求，也不能用媒体类型或 CSS 满足文字断言。七/八步阅读合同、动作表单、内容初筛与验证回看接通新类型。
+- 新回放保存 `step_timings` 与 `verify_timing`，分别记录真实步骤状态、独占阶段、入口、总额及关闭耗时。未进入阶段及旧记录不补零；超时只保留实际前缀，返回值复制，迟到回调不能补成成功。后端严格校验步位/动作/状态、阶段前缀及耗时和，非法轨迹拒绝；阅读和验证界面可回看。
+- 实测发现动作前重复整页候选发现成本高，改为在同一个 `describePage` 固定函数内，只查已观察定位或批次滚动根，复用原元信息、敏感判断和定位语义。普通定位须保持 canonical CSS，集合仍核对数量、类型及代表对象；最新观察、动态唯一匹配、固定对象、来源和请求检查保留。每步后及每批仍完整观察、遮罩并生成 PNG；清单、请求策略、单步/总额及 RPC 预算均未增加。无数据库 schema 或迁移变化。
+
+真实平台事实：
+
+- 重开同资料仍为可见页面检测 `logged_in`，沿用维护者此前明确确认的账号。独立探查任务 `learn_b16ed35d86524e1a929ff8b5c191f4d2` 正常搜索并进入原第二篇后，评论容器明确滚动 **480 像素一次**，实际观察并提取到 1 条纯图片评论。探查保留 **9 步、21 份观察、无候选**：[图片结构探查](../.tmp/xhs-media-probe-content.json)。没有从接口或媒体文件推断内容。
+- 首次干净录制 `learn_1e35c8cb0f824d45ac45e0d34a1218f5` 的评论阶段先得到一批 3 条，随后 `STALE_TARGET`；实际截图出现详情关闭过渡，最终回到搜索页。同次有 1 条 collect POST 被阻止，但证据不足以确定关闭原因，未据此扩大网络策略或归因给平台/人工。保留 **7 个成功步骤、19 份观察和失败批次，无候选**：[不完整录制](../.tmp/xhs-media-candidate-failure.json)。另建任务录制，原失败未覆盖。
+- 新任务 `learn_b24e405266144037b506d63cb97a1ce8` 录完八步，冻结 **`candidate_9d11e4266ec24f3e89b0b82e49b9ff9d`**，摘要前缀 **`558555f4d3f2`**，静态通过。依据实际图片位置，新范围为 **首层最多 6 条、每批 480 像素、含首批最多 3 批、15 秒批次预算**；搜索定位仍每次 320 像素、最多 5 次、10 秒，总预算 100 秒。录制得到 5 条文字和 1 条图片、2 批；原 5 条/320 像素文字版本保持不变。
+- 性能修订前，第二篇 `reading_6289d97eca864db8ad50ca4d1a782330` / `validation_6a62dbba43f54d6e8e79291365bc8cbf` 约 **100.6 秒（含后台保存）失败**，工作进程 100.012 秒，实际定位滚动 **2 次、0→320→640**。链接/页面 ID 和标题已正确，但第 7 步后置取证被硬截止中断，正文输出未返回，评论未执行；保留 7 份证据，关闭并暂停会话。`NOTE_BINDING_MISMATCH` 在此表示可用输出不足，不能解释为已点错编号。阶段显示当前检查合计 **41.437 秒**、后置取证 **42.927 秒**：[优化前阅读](../.tmp/xhs-media-before-target-check-reading.json)。同次关闭后的另一次阅读请求 `reading_92688f496b01428fb02af951904cdad4` 被 `browser_session_required` 拒绝，无验证、输出或证据，也保留为失败。
+- 性能修订加载后，重开并确认同账号，**同一冻结候选**追加第二篇 `reading_b1f787aaa4334a5eabeb8b56bb95ecbf` / `validation_b3b21364e084402dbd46cf6d4169d5a3` 探索通过：工作进程 **46.039 秒**，含保存约 **47.1 秒**；1 篇正文、**6 条首层评论（5 文字、1 纯图片）**，2 批、重复 0、条数上限结束，11 份证据。当前检查合计 **0.199 秒**；后置取证 27.186 秒、批次取证 8.553 秒。实际批次 PNG 已人工查看，图片存在且完整；内容未解释。
+- 同候选变参首篇 `reading_379e073f152648caae18b3daa2b610ea` / `validation_65f114ad964b4fb3b3f34710f46f1abc` 探索通过：工作进程 **48.761 秒**，含保存约 **50.0 秒**；1 篇正文、**6 条文字首层评论**，3 批、重复观察去掉 1 次、条数上限结束，12 份证据。两次追加探索的目标在当前结果中均为零滚动；此前同候选 2 次实际移动属于失败历史，不能据此称性能修订后已完成更多结果位置验收。两篇均核对链接、页面 ID、标题与两输出来源，`truncated:true`，未展开回复或读完全部评论。
+- 最终该初筛 **9 条阅读历史**：本轮新增 2 完成、1 有完整验证的预算失败、1 未就绪拒绝，原 5 条逐字读回不变。新任务 **51 份观察、8 步、1 候选、4 验证**（静态、优化前探索失败及优化后两次探索通过）。原搜索/文字八步清单摘要、原初筛、5 条阅读及 3 条旧文字八步验证、新候选冻结清单摘要均不变：[实际最终摘要](../.tmp/xhs-media-final-summary.json)。新版本仍为 **experimental、published:false**；旧正式候选仍 `awaiting_observation`：[旧质量与真实截图索引](../.tmp/xhs-media-evidence-status.json)。没有根据时间经过或本轮成功自动补无异常反馈。
+
+工程验证与边界：
+
+- 后台完整 **87 passed、无跳过**，约 **384.3 秒**，包含 SQLite 和实际专用测试 PostgreSQL；覆盖新内容字段/轨迹清洗、旧合同、持久化及不可变记录：[87 项输出](../.tmp/test-server-content-timing-87.log)。之后仅增加入口、步骤和关闭的独占耗时总和校验，受影响 **3 passed、84 deselected、无跳过**，约 **45.0 秒**：[最终耗时目标](../.tmp/test-server-timing-exclusive-target.log)。未在该校验后重复全量，不相加为 90。只有既有 TestClient 弃用提示。
+- 性能修订前 worker 单轮 **62/62**：[媒体与耗时阶段回归](../.tmp/worker-regression-IcEMUS/report.json)。限定检查后先 **9/9** 定向：[元信息与门禁目标](../.tmp/worker-regression-8nTVUB/report.json)，随后最终单轮 **65/65**：[最终完整回归](../.tmp/worker-regression-xQ93Pe/report.json)。包含真实隔离 Edge 的元信息等价及禁止全页枚举夹具、canonical/敏感/固定根变化、零项等待、有界定位、媒体、原合同与硬截止；不是 65 个真实平台样本，也不与 62 或定向次数相加。
+- 媒体 PG + Edge 完整 API/UI 验收先在耗时校验后通过：[前阶段验收](../.tmp/reading-media-acceptance-1792833328561/summary.json)；性能修订后独立完整重跑通过：[最终界面验收](../.tmp/reading-media-acceptance-1792835480551/summary.json)。覆盖 `data-testid`/集合定位、7/8 步内容候选、文字/图片/混合和截断、实际 PNG、来源绑定、首层 3 条/2 批、阅读/验证耗时 UI、hash、历史及重启。旧 text 遇纯图片、真正空 content 仍部分失败并保留正文；4 条合成阅读为 2 完成/2 部分，`received_writes=0`、`errors=[]`。最早脚本因未切“验证记录”标签失败的报告保留，修脚本后才有上述完整结果，未放宽产品合同。
+- 本轮 UI 类型检查与生产构建通过，之后仅脚本修正和 worker/API 受影响修订，UI 未再改动；没有重复构建。语法、文档链接及差异检查通过；更新图解 8 页无脚本/几何问题：[离线图解检查](../.tmp/plan-qa/checks.json)。迁移、检索扩展、macOS、模型准确率/费用、新候选正式模式、商家发布和写操作未执行。
+
+涉及范围：worker/动作合同及媒体/元信息回归、后端学习/阅读契约与 `test_content_timing.py`、表单/类型/内容初筛/验证回看、新 `ExecutionTimings.tsx` 与 `scripts/test-reading-media.mjs`、命令入口，以及现有 README、工具说明、整体方案、图解和本进度。A2A 原工程保持只读，共享工作区原有改动保留。
+
+未完成与下一步：按整体方案第 14.2 节接可配置模型，先用真实可用文字区分需求与信息不足，媒体不解释；结合人工样本核对误判漏判及成本。真实混合/视频评论、更多位置和异常分支仍未学习，有限两篇通过不代表所有任务稳定或账号不会收到后续提醒；原正式候选仍待到期后的实际反馈，独立读回、双端与发布未完成。
+
+结束检查：更新服务已加载，API 与前端代理 health 正常、前端首页 200，数据库为 PostgreSQL；当前专用会话为 ready / logged_in，停留最后首篇阅读，没有自动继续任务。服务依赖本机开发进程，不代表永久在线。

+- 参考工程 `.env` 使用官方 DeepSeek、`deepseek-flash`，主 Key 与备用 Key 均存在且值不同，另一个 Hub 配置重复主 Key，并非第三个独立备用。只核对环境与源码，未查参考数据库，不能声称其运行配置未被后台覆盖，也未验证账户是否独立。原工程不修改。
+- 原工程主要在余额不足时切备用。本项目实现同提供商/型号的有限 Key 切换，不引入其完整 Browser Use 模型恢复架构，不因为模型失败重放浏览器。两个 Key 已按授权导入本项目忽略的本机配置，未写入源码、前端或文档，未打印密钥值；真实 Key 不随仓库分发。
+- 按本日核对的 [官方型号与价格说明](https://api-docs.deepseek.com/quick_start/pricing/)，`deepseek-flash` 对应 V4.1-Flash-1017，旧 V4 Flash 已转新版，不能凭填旧名称认定调用旧模型。首轮选 Flash、关闭思考，按实际文字判断质量/每任务用量决定后续型号；没有执行 4.0 与新版对比，也不认定版本旧就更便宜。真实响应只返回 `deepseek-flash` 别名，未取得独立修订号，不将官网映射冒充逐次响应的精确版本。
+
+工程完成：
+
+- 新增服务端 `ModelConfig / ModelClient` 和需求分析服务，配置仅由 `ASSISTANT_MODEL_*` 环境读取，界面只展示安全状态、型号、去重后的主备槽位及限值。`model_configured` 与“真实调用成功”分别表示，旧 health/readings/discovery 的 `model_connected:false` 不被改写为历史调用过。
+- 复用 OpenAI-compatible Chat Completions 的 JSON 输出，默认非思考、最多 4096 输出 Token，可配置且上限 8192。单请求最多 30 秒、合计最多 60 秒；最多两个不同 Key。仅 401/402/429、5xx、网络及超时可转备用；400/重定向、响应过大、截断、结构或业务依据失败不切换。禁跟重定向，响应上限 262,144 字节，不保存原始提供商错误或思考内容。
+- 模型输入只取已绑定阅读的文字与临时 `source_ref`，不发作者、真实笔记/评论 ID、来源 URL、媒体 CSS/图像或凭据。最多 21 个来源、16,000 字，超限 422 且不调用，不自动截断。有正文的有效 partial 可分析，failed/无正文/来源核对未通过拒绝。纯媒体不发模型，由程序补信息不足、媒体未解释。
+- 结果固定为明确需求、疑似需求、普通讨论、信息不足；逐源核对覆盖、唯一引用、逐字证据，装修阶段/地区/预算的值须包含在本源证据中。额外联系人等字段、跨来源引用、编造证据或不合法分类失败。身份始终未确认，缺失项由程序枚举，不让模型补人群画像。
+- `analysis_runs` 为独立不可变事实，SQLite/PG schema 7，关联阅读摘要、配置摘要、提示/结果版本、来源、主备尝试、用量、失败及未知费用。只追加，不改原初筛/阅读/候选；迁移兼容旧库无分析表，按依赖在阅读后复制，保持整体回滚及非空目标拒绝。开发数据库仅启动时增表，未执行 SQLite 数据迁移。
+- 新增安全状态、分析创建/列表/详情四类 API，沿用鉴权和 CSRF。相同阅读/配置/提示与结果版本的完成记录直接复用；Key 轮换不改变结果缓存，进行中 409，失败不自动再调用。后台阅读详情展示逐项原文/依据/缺失、媒体未解释、主备、已返回 Token、失败和历史；修复新卡片 grid 被表格持续撑宽导致按钮不稳定的问题。
+- 边界复审发现深层 JSON 可抛 `RecursionError` 而不留失败，已转为安全格式错误，wire 与内容两层均覆盖；最终又收窄密钥配置为可见 ASCII，中文/emoji 坏配置返回未配置、零调用，避免请求头编码异常。未修改正常 ASCII Key 的调用语义。
+
+真实模型与质量观察：
+
+- 未搜索或重新读平台，直接分析上一轮两条 completed 阅读，原初筛及全部 **9 条阅读**、冻结候选清单/摘要逐字读回不变。v1 两条分析结构和依据校验通过、主 Key 各一次 HTTP 200，约 1.6–1.7 秒，分别 696/880 Token；人工抽查发现把询问他人地区/装修进展和推荐设计师误判为疑似需求，不能因接口成功就认定模型质量通过。
+- 保留 v1，提示修订为 **`renovation-demand-v2`**：明确判断发言者自身需求、评论不能继承笔记作者需求，并补询问/推荐反例。独立开发者标注合成集 **9 项与标签一致**：模型判断 8 段文字，另 1 条纯媒体由程序标信息不足；含自身需求、询问他人、推荐、建议、已完工与短文字不足。仅 1 次官方模型请求、1178 Token；不是 9 次 API 或真实客户准确率：[小样例核对](../.tmp/demand-eval-renovation-demand-v2.json)。
+- v2 对原两条阅读各追加一次，未覆盖 v1。`analysis_360ac874ace0422189c288e79efd412b` 约 **1.703 秒**，输入 725、输出 221、总 **946 Token**，缓存命中 384；`analysis_1bb7d85b373040759a1b0e6df6ccb6a7` 约 **1.625 秒**，输入 818、输出 284、总 **1102 Token**，缓存命中 384。两次均主 Key 成功，响应别名 `deepseek-flash`，未实际触发备用。
+- v2 两篇共 **14 项**：2 个笔记需求信号、1 条疑似评论、8 条普通讨论、3 条信息不足（含 1 条纯图片）；13 段文字送模型，媒体不解释。此前“询问对方进展/推荐设计师”的误报已改为讨论；“半包”相关评论仍有建议或自身需求歧义，留待人工核对，不计为确认客户。地区/预算/阶段未据条件补值。真实业主、商机转化、漏判/误判率均未验收。
+- 本轮真实模型调用共 **5 次**：v1 两次、v2 两次及合成样例一次，全部使用主 Key；4 条真实内容分析记录与旧事实均保留。同配置再次 POST 返回同一 v2 记录且逐字不变，未新增分析：[复用核对](../.tmp/demand-live-reuse.json)。汇总：[真实调用与历史核对](../.tmp/demand-live-summary.json)。Token 仅为已返回用量，未核对提供商实付账单，费用为 unknown；没有把备用 Key 配好等同于其额度/容灾已实测。
+
+工程验证与阶段：
+
+- 初期模型目标 **22 passed、87 deselected、无跳过**，SQLite 与实际专用 PostgreSQL，覆盖输入/归属/不可变/复用/坏依据/主备/超时/深层 JSON。schema 7 迁移隔离 **17/17**，17 个随机 schema 清理，含新分析数据顺序、旧库缺表、非空目标和失败回滚：[迁移回归](../.tmp/migration-regression-objtqyh7/report.json)。没有向开发库迁入测试数据。
+- 首轮完整后台 **108 passed、1 failed、无跳过**，约 **387.4 秒**，仅旧 PG `TRUNCATE reading_runs` 因新外键在不可变触发器之前拒绝；数据未修改。按已有同类测试处理，只改断言用 `TRUNCATE reading_runs CASCADE` 使原事实保护触发，不扩大 Store 的数据库错误映射。原失败日志保留：[前阶段完整输出](../.tmp/test-server-model-full.log)。随后 v2 与旧/新不可变目标 **24 passed、85 deselected、无跳过**，约 32.2 秒：[最终受影响目标](../.tmp/test-server-model-target-fk-cascade.log)。
+- v2 提示及 CASCADE 测试修正后的单轮完整后台 **109 passed、无跳过**，约 **432.3 秒**，包含 SQLite 与实际专用 PostgreSQL：[完整后台输出](../.tmp/test-server-model-full-final.log)。该轮在最后可见 ASCII Key 校验修改前启动；随后该输入校验的受影响目标 **1 passed、108 deselected、无跳过**，约 2.3 秒：[输入校验目标](../.tmp/test-server-model-ascii-env.log)。没有在该修改后重复全量，不相加为 110；仅既有 TestClient 弃用提示。
+- 最终完整 **PG + Edge + 本机假模型** API/UI 单轮通过，保存 4 条分析（完成 2/失败 2）、6 次仅本机模型请求；覆盖正常、主失败/备成功、双失败、坏依据拒绝、纯/混合媒体、用量未知不补 0、同 ID 复用零新增、历史/hash/刷新及重启。分析阶段平台请求新增 **0**、写操作 **0**、`errors=[]`，原始提供商错误及假密钥未进入页面/记录/日志：[最终界面验收](../.tmp/demand-analysis-acceptance-1792844588112/summary.json)。此前脚本 schema 前缀和 grid 不稳定失败保留，修复后的前一通过轮与最后补用量/截图断言轮分别留存，不累计次数。
+- 最终前端类型检查、生产构建、受限控制传输、语法与差异检查通过，构建仅既有 chunk 提示。现有图解 8 页无脚本/几何问题；实际 Key 对修改/新增源码与产物的精确匹配扫描为 0，`.env` 被 Git 忽略：[本机交付检查](../.tmp/demand-final-qa.json)。没有重跑未变的 worker 全套或检索扩展，未做 macOS、完整商家计量、模型对照、独立读回、新正式候选发布或任何外联写操作。
+
+涉及范围：新增 `apps/server/model_client.py`、`analysis.py` 与 `tests/test_analysis.py`，后端 API/SQLite/PG/迁移及其测试、`ReadingDemandAnalysis.tsx`/阅读页/类型、新 `scripts/test-demand-analysis.mjs` 与命令、控制入口、`.env.example`、现有 README/工具说明/整体方案/图解/本进度。参考工程只读，共享工作区原有改动保留。
+
+未完成与下一步：按整体方案第 14.2 节扩大人工标注，核对发言主体、商家推荐/建议与自身需求的歧义，比较候选型号的准确性、耗时与实际每任务成本，再形成带依据的线索；本轮两篇及 9 条基础样例不能替代业务评测。媒体语义、真实备用 Key 故障切换、完整费用、账号后续反馈、双端与正式发布仍未完成。
+
+结束检查：最后 ASCII 校验修订已加载，本机前端 200、API/代理 health 正常，PostgreSQL，模型安全状态已配置；服务重启已关闭原平台浏览器，会话未自动恢复。重启后相同 v2 分析仍返回原 ID 和原记录，4 条分析、原 9 条阅读及候选摘要不变。内容分析和历史回看可在无平台浏览器时使用。提交/推送：本轮未执行，所有模型凭据、真实记录和临时报告保留本机忽略目录。
+
+## 2026-10-24-16：“查看分析”显式打开详情侧栏
+
+目标：修复用户截图中“查看分析”点击缺少反馈、无法找到逐项原文依据的问题。
+
+实际完成：
+
+- 核对原实现：历史加载默认选第一条，按钮只更新选中 ID；同条再次点击没有状态变化，其他条也只在长页面表格下方静默替换内容，且原文排在配置/用量/主备信息之后。此前指导继续向下寻找，未解决入口反馈问题。
+- 在 `ReadingDemandAnalysis.tsx` 增加独立详情打开状态。历史按钮每次选定记录并打开页面级侧栏，同条关闭后可重开；创建或复用分析完成也直接打开。保留阅读/初筛归属过滤、请求代次及换阅读卸载逻辑，查看/关闭不请求新分析或修改历史。
+- 侧栏优先显示状态、提示版本、时间和逐项需求/原文/依据；模型配置、Token、主备请求及摘要改为默认折叠。宽度取 `min(880px,100vw)`，保留可访问关闭名称和弹窗语义，关闭销毁内容后重开恢复首屏。
+- 核对时本机 8810/5179 均无监听，已重新启动现有开发服务；未据此断言服务停止原因或将它当作原点击行为的唯一原因。更新模块实际由本机前端提供，API/代理 health 正常。
+
+验证与证据：
+
+- TypeScript 检查与生产构建通过，构建仅既有 chunk 提示；产品冻结后未再改代码。差异及脚本语法检查通过。
+- 适配 `scripts/test-demand-analysis.mjs` 并完成单轮隔离 **PostgreSQL + Edge + 本机假模型** 验收：[最终报告](../.tmp/demand-analysis-acceptance-1792846679071/summary.json)。实际点击历史行按钮，确认正确记录的侧栏及原文进入视口；覆盖同条关闭重开、另一条/失败详情、创建/复用自动打开、刷新及重启后再从历史打开。关闭前后历史逐字相同，查看阶段模型请求不增加。
+- 980×760 视口的侧栏边界为 x=100..980、y=0..760，原文与依据首屏可见，无横向溢出；已查看实际视口截图：[小窗口详情](../.tmp/demand-analysis-acceptance-1792846679071/demand-analysis-small-screen-visible-original.png)。整轮保留 4 条合成分析（完成 2/失败 2）、6 次仅本机模型请求；分析阶段平台请求新增 0、写操作 0、`errors=[]`，不代表真实模型或平台重新验证。
+- 首轮脚本误将笔记原文按单独正文精确匹配，而服务既有原文为标题加正文，造成定位超时；产品当时已展示侧栏。失败证据保留在 `.tmp/demand-analysis-acceptance-1792846580423`，仅修脚本使用实际 source.text 后才有上述最终通过，未放宽产品或改写失败。
+- 实际账本只读核对：原初筛、9 条阅读、4 条分析及候选清单/摘要不变，v1 分析仍逐字保留：[账本核对](../.tmp/demand-click-ledger.json)。本轮未调用真实模型、未操作平台浏览器，后端/schema/worker 均未变，未重复 109 项后台、worker 或迁移回归。
+- README、整体方案第 14.2 节与现有图解已同步查看方式及人工标注未实现的边界；离线图解 8 页无脚本/几何问题，文档链接检查通过。
+
+涉及文件：`apps/admin/src/components/ReadingDemandAnalysis.tsx`、`scripts/test-demand-analysis.mjs`，现有 README、整体方案、图解与本进度。保护共享工作区原有改动，参考工程、模型配置及真实资料未改。
+
+未完成与下一步：仍按整体方案第 14.2 节推进人工标注、纠错与业务质量评测。侧栏用于查看已有分析，不等于已保存人工核验，也未新增确认客户或发布能力。
+
+结束检查：本机前端可提供侧栏修订，API/前端代理 health 正常、前端首页 200、PostgreSQL；服务仍依赖本机开发进程。提交/推送：本轮未执行，截图和报告保存在忽略的本机目录。
+
+## 2026-10-24-17：商家需求工作台与多维内容判断
+
+目标：在学习后台验证“当前商家要找谁 → 已学链路取得内容 → 谁在表达什么需求 → 是否匹配及下一步建议”，形成未来桌面可接的轻量业务合同，不前置完整 A2A 调度或桌面工程。
+
+实际完成：
+
+- 新增 `BusinessBriefService` 及后台“商家需求 · 业务验证”入口，接解析、缺项、范围不支持与失败状态。平台、装修服务、目标业主、最多 3 个搜索词、地区和是否排除服务推广逐字段核对原文，不猜条件。维护者确认须显式提交全部字段，可保留地区未知；追加确认记录、父摘要和 `maintainer_edit`，不改草稿或伪造模型依据。
+- SQLite/PG schema 8 新增不可变 `business_briefs`、父引用及复用索引；实际开发库仅启动增表，没有迁入测试数据。确认本身不调用模型；有效解析同输入/配置/版本复用，失败不自动重试。沿用已有服务端主备、超时与用量合同，不向前端暴露真实 Key。
+- 新增 5 类商家需求 API 与 `briefs.list/get/create/confirm/discover` 受限维护入口，沿用鉴权、CSRF、归属核对。确认后的初筛只接候选和条数，由服务端取条件并执行第一个搜索词，不自动调度其余词、登录或切换账号。新初筛和阅读保存确认编号/摘要；原结构化入口和旧记录保留。
+- 内容提示升为 `renovation-demand-v3`、结果 `demand-result-v2`。独立保存当前发言角色信号、多选表达、自身需求与业务相关性；“自己准备装修”可同时提问/求建议，服务方也可有自身需求，短问句不确认服务方。逐源引用校验，阶段、地区、预算仅取该发言者自身项目；媒体未解释。
+- 分析支持同维护者确认条件，默认继承阅读绑定；旧阅读可显式选择条件，旧 `POST {}` 沿用原初筛条件并注明来源。上下文摘要参与复用，改条件不误用旧结果。匹配及建议由程序固定派生，地区未知/缺项目地/不同地名均保留待核；排除纯服务推广不屏蔽服务方自身需求或同行笔记下面的需求评论。建议只展示，不执行互动。
+- 原详情侧栏新增条件快照、角色/表达依据、相关性、匹配理由及建议，兼容旧 v1/v2 历史，不补造旧维度。README、整体方案第 14.2 节和现有图解同步共享业务层与实施顺序。
+
+真实模型与有限业务观察：
+
+- 本机服务重启后，维护入口核对原初筛、**9 条阅读、4 条旧分析**及冻结候选，作为新增前基线。输入已讨论的装修找业主样例，实际解析一次主 Key HTTP 200，约 **0.985 秒、487 Token**，准确保留地区未知与推广排除待确认，状态 `needs_clarification`，未默认全国。
+- 由本轮开发维护者执行测试确认：装修服务、目标业主、搜索装修、地区未知、不额外排除推广。保存独立确认版本；这是维护者测试条件，不能记作用户亲自操作确认或正式商业配置。确认未调用模型，未启动搜索/阅读浏览器。
+- 在确认条件下对两条已有 completed 阅读各新增 v3 分析，主 Key 均 HTTP 200，约 **2.235 秒/1599 Token**、**4.250 秒/2399 Token**。首篇作者为自身明确需求并同时提问/求建议；短评论角色保留未知，半包相关句按建议/参与者处理，不能据此确认账号身份。第二篇推荐设计师为服务推荐信号而非评论者自身装修需求，其地区不当作本人项目地。地区未设，因此作者有需求也不判定地域匹配。分类仍需人工标注，不能凭两篇证明业务准确率。
+- 本轮真实模型调用 **3 次**（解析 1、已有阅读分析 2），均主 Key，合计已返回 **4485 Token**，费用仍 unknown，未强制触发真实备用。重复分析返回同一记录且逐字不变；原初筛、9 条阅读、候选及 4 条旧分析全部不变，现在共 6 条分析。平台浏览器保持关闭，本轮真实平台动作与互动执行均为 0：[真实调用与不可变核对](../.tmp/business-live-summary.json)。
+
+工程验证与证据：
+
+- 分析模块纯函数/SQLite 定向 **46 passed、4 deselected**，商家需求定向 **8 passed**（含专用 PG），新增 API 桥接 SQLite 定向 **1 passed、1 deselected**；这些是阶段目标，不能与完整套件累加。
+- 产品冻结后的单轮完整后台 **147 passed、无跳过**，约 **427.53 秒**，含 SQLite 与实际专用 PostgreSQL，覆盖新旧分析、商家条件、API 桥接、归属和不可变事实：[完整后台输出](../.tmp/test-server-business-full.log)。仅既有 TestClient 弃用提示；本轮未重复 worker 全量或旧需求分析独立端到端，不将之前次数相加。
+- schema 8 独立 PG 迁移 **21/21**，21 个随机 schema 清理，覆盖草稿/确认自引用、精确 payload/顺序、旧库缺表、非空目标拒绝及父引用坏时整体回滚：[迁移报告](../.tmp/migration-regression-smupvvic/report.json)。未向开发库复制测试数据。
+- 最终独立 **PostgreSQL + Edge + 本机假模型** 端到端通过：[业务验收](../.tmp/business-workbench-acceptance-1792849528526/summary.json)。实际 UI 覆盖解析/复用、原文缺项、显式补条件追加、桥接搜索及单篇阅读、条件引用传递、多轴分析、相同条件复用/不同条件新增、范围不支持/双 Key 失败、旧 v1/v2 查看、同条重开与重启不变。保存 5 条合成需求、2 条新分析及 2 条合成旧历史，6 次仅本机模型请求；解析/分析期间平台请求新增 0、写操作 0、`errors=[]`。
+- 980×760 分析侧栏 x=100..980、y=0..760，横向溢出 0；已查看实际确认与小视口截图：[小窗口多轴详情](../.tmp/business-workbench-acceptance-1792849528526/analysis-small-screen.png)。确认截图显示维护者新增地区和原始输入分开，不将补充条件当作原文。
+- 两次前序端到端脚本失败证据保留：`.tmp/business-workbench-acceptance-1792849373736` 使用 AntD 隐藏辅助 option 定位；`.tmp/business-workbench-acceptance-1792849428644` 未等待历史刷新结束就关闭 busy 侧栏。仅修脚本可见定位与就绪等待，未放宽产品。旧 `test-demand-analysis.mjs` 的假模型同步新合同并通过语法检查，本轮没有完整重跑该旧脚本。
+- TypeScript 检查、生产构建及两个相关脚本语法通过；构建仅既有 chunk 提示。维护入口映射、路径校验、CSRF、无自动重试目标测试通过。离线图解 8 页无脚本/几何问题，链接检查通过。真实 Key 精确扫描工作区修改/新增文件与生产包无命中，`.env` 仍忽略；本机 API/前端代理 health 正常，首页 200。
+
+涉及文件：新增 `apps/server/business_briefs.py`、`apps/admin/src/components/BusinessBriefPanel.tsx`、`scripts/test-business-workbench.mjs` 及目标测试；修改分析、主 API、初筛/阅读、存储/迁移、后台类型/页面/详情、维护控制入口及现有文档。保护共享工作区原改动，参考项目和真实模型配置未改。
+
+未完成与下一步：按整体方案第 14.2 节保存人工核对/纠错及建立有限真实业务样本集，补地区和歧义例，再扩同行内容评论路径。当前查看不等于人工标注保存；未知地区、身份与内容质量不自动晋级。未新增真实平台搜索/阅读、正式发布、独立读回、桌面、macOS 或商业额度结算验收，原正式候选观察状态不因本轮模型分析而改为通过。
+
+提交/推送：本轮未执行；模型凭据、真实账本、截图及临时报告保存在本机忽略目录。
+
+## 2026-10-24-18：人工核对、纠错修订与样本统计
+
+目标：完成上一阶段确定的人工核对保存，让维护者对少量真实样本显式判断；需要用户参与时给出具体入口和操作步骤，不由程序或 Codex 代写真实人工结论。
+
+实际完成：
+
+- 在分析详情新增醒目“人工核对”统计和每来源“核对此条”入口。核对侧栏保留本条原文、原模型五轴和人工历史，首次预填但不预选决策、也不自动保存。维护者可选择判断正确、需要修正、暂不能确定或当前文字不可核对；修正须改变至少一轴、填写说明和 1–3 条本来源逐字依据。无文字媒体只允许未判定状态，旧结果结构保持只读。
+- 新增 `AnalysisReviewService`、四类核对/详情/统计 API 及 `reviews.list/create/summary/get` 受限维护操作。鉴权、CSRF、分析/来源归属、逐字引用、五轴一致性及既有地区条件由服务端核对。不能给缺少自身需求或地域不足的来源标成匹配，不接受联系方式、凭据或控制字符备注；无模型或浏览器调用。
+- schema 9 的 `analysis_reviews` 保存 `analysis-review-v1`、原分析和来源摘要、原模型标签、维护者、人工标签、依据、说明和前版引用。SQLite/PG 阻止更新、删除及 PG 截断，首版/后继唯一约束配合事务最新版本比较；旧表单及并发失败返回 `409 REVIEW_STALE`，不覆盖前一版或自动重发。
+- 核对结果与原分析分开，纠错或后续改为不确定均追加版本。统计每源最新版本的待核对、已确认、已纠错、有争议、文字不可核对，另计五轴差异。一致率分母只含已确认/已纠错，无已判定样本为 null；未核对、暂不能确定和媒体不算正确或错误。当前界面是可见模型建议的辅助核对，不能当作独立评测准确率、精确率或召回率。
+- 前端防连续点击、卸载和来源切换错写；409 或网络结果未知时先刷新并要求关闭重开，不自动重试。明确 422 校验拒绝则显示安全校验原因，保留表单供修正后显式保存。保存成功、422 及 409 反馈通过独立状态容器和滚动进入当前侧栏视野，保留无障碍状态提示，避免长表单只看到禁用按钮而找不到原因。README、整体方案第 14.2 节和现有图解同步入口、记录语义及后续样本顺序。
+
+工程验证与阶段证据：
+
+- 核对服务 SQLite 定向 **6 passed、6 deselected**，PG 参数留给统一全套；覆盖修订链、归属、逐源依据、媒体/地区/标签限制、并发首版/后继单一成功、状态统计、原分析/阅读不变及实际重新打开存储：[定向输出](../.tmp/test-analysis-reviews-sqlite.log)。这些是阶段目标，不与完整套件累加。
+- 后台产品及测试冻结后的单轮完整 **159 passed、无跳过**，约 **458.32 秒**，包含 SQLite 与实际专用 PostgreSQL；仅既有 TestClient 弃用提示：[完整后台输出](../.tmp/test-server-reviews-full.log)。没有重复 worker 全量或旧商家工作台完整浏览器套件，旧测试次数不累加为本轮结果。
+- schema 9 独立迁移 **27/27**，清理 **25 个随机 PG schema**；包含修订自引用/精确 payload/顺序、旧库缺表、非空拒绝、坏前版整体回滚，以及 SQLite/PG 并发首版及后继唯一约束：[迁移报告](../.tmp/migration-regression-v_9twrcl/report.json)。开发库仅启动增表，没有迁入合成数据。
+- 首轮迁移验证的旧 `TRUNCATE analysis_runs` 因新增外键在事实触发器前被 PG 关系依赖拒绝，数据未变；只将该迁移断言及后台同类测试改为 `TRUNCATE analysis_runs CASCADE` 以到达原不可变保护，未扩大数据库错误映射。原失败保留在 `.tmp/test-migration-reviews.log`。
+- 最终单轮独立 **PostgreSQL + Edge + 本机假模型** 浏览器验收通过：[人工核对报告](../.tmp/analysis-review-acceptance-1792851620367/summary.json)。合成四来源与一条新版分析，实际 UI 完成四种决策、逐字纠错、防双击单 POST、422 展示安全原因且保留可编辑表单、追加修订、409 拒绝旧版本且须重开、旧结构只读与重启历史保存。成功追加 **7 条核对**，最终每源最新为确认 1、不确定 2、文字不可核对 1，已判定 1；历史修订不累加统计。原模型分析、阅读、初筛逐字不变，核对期间模型调用新增 0、平台请求新增 0、写操作 0、`errors=[]`。准备样本的模型为仅本机假服务，不是本轮真实提供商调用。
+- 已查看纠错保存和 980×760 小视口实际截图，核对侧栏 x=220..980、y=0..760，原文和历史可见、横向溢出 0：[小视口核对](../.tmp/analysis-review-acceptance-1792851620367/review-small-screen-original.png)。测量仅取当前核对侧栏自身 wrapper，并等待动画结束及连续稳定帧，未用被推移的父分析侧栏冒充当前几何。成功、422 及 409 提示均另经实际视口裁剪断言，已查看最终校验和冲突反馈截图。
+- 前两轮浏览器脚本失败证据保留：`.tmp/analysis-review-acceptance-1792850862545` 在纯媒体下拉渲染前读取全部选项，补可见就绪等待；`.tmp/analysis-review-acceptance-1792851118936` 小视口误取嵌套的父侧栏/未稳定几何，补自身对象及稳定帧测量。均未放宽最终边界断言。两轮之间另完成上述 422 可继续纠错的产品改进，最终验收包含该行为；未用前轮局部成功代替最终通过。
+- 第三轮完整浏览器阶段在 `.tmp/analysis-review-acceptance-1792851302009` 已通过；之后只读复核发现长表单的 409 提示在上方屏外，阶段断言只验证 DOM，不能证明用户能看到反馈。补上述前端反馈滚动后才执行最终一轮；后台服务与测试未再改，159 项结果适用于该后台版本，没有为纯前端交互修订重复全量。
+- TypeScript 检查、生产构建和脚本语法通过，构建仅既有 chunk 提示；维护控制入口目标回归通过。离线图解 8 页无脚本/几何问题，文档链接有效。代码、备注输入与统计语义经过交叉只读复核，代码审查不代替实际验收。
+
+真实数据核对与待人工状态：
+
+- 通过受限维护入口保存新增前基线，重启并加载新 API 后逐字读回：原初筛、**9 条阅读、6 条分析、2 条商家需求**、冻结候选均不变。两个新版分析各有 **7 项待核对、0 项已判定**，一致率为 null；旧结构不制造可编辑样本或待办：[只读账本核对](../.tmp/review-live-summary.json)。
+- 本轮真实模型调用、真实平台动作和真实人工标注写入均为 **0**；没有把之前对话里的业务直觉或合成验收结果自动登记为人工结论，也没有写入账号观察/发布状态。
+- 结束时本机 API/前端代理 health 正常、前端首页 200、PostgreSQL；真实模型 Key 对修改/新增文件和生产包精确扫描无命中，`.env` 仍忽略。服务依赖当前本机开发进程，不据本次在线承诺永久可访问。
+- 当前由用户先核对第一篇的正文、首层评论 1 和 2。入口为当前阅读页面“装修需求判断”中最新分析的“查看分析”，逐条点“核对此条”；同意全部五轴选判断正确，不同意选需要修正并填依据，不能确定选暂不能确定并说明原因，再显式保存。用户实际保存后再根据记录继续质量改进，不能把入口已做好记作业务标注已完成。
+
+涉及文件：新增 `apps/server/analysis_reviews.py`、`apps/server/tests/test_analysis_reviews.py`、`apps/admin/src/components/AnalysisReviewPanel.tsx`、`scripts/test-analysis-review.mjs`；修改 API、存储/迁移、旧不可变测试、后台类型/分析详情、维护控制入口、package 和既有文档。共享工作区原改动及参考项目保留，真实模型配置未改。
+
+未完成与下一步：按整体方案第 14.2 节等待实际少量人工核对，再补地区、歧义和同行评论需求样本，建立独立标注集后评估误判漏判。当前没有自动重训、批量纠错、完整评测看板、真实媒体理解或正式客户确认；未新增平台链路、独立读回、桌面/macOS、商业费用或发布验收。

+
+## 2026-10-24-19：首批真实样本逐条人工核对
+
+目标：将用户在对话中明确确认的具体样本判断，通过既有核对入口代录；逐条推进，不将一般业务讨论当作其他来源的人工结论。
+
+实际完成：用户确认首篇正文为作者自身准备装修、同时提问/求建议、疑似需求方且与装修服务相关；地区未知，匹配仍待核。通过 `reviews.create` 保存 1 条 `confirmed`，备注明确“用户在对话中同意，由 Codex 代录”，附本篇逐字原文依据。仅对应首篇 `note`，未保存评论 1/2 或其他样本，不确认账号身份、地域或实际客户。
+
+验证：实际 API 新增后按编号读回一致；原分析与既有核对保持不变。首篇统计为 7 个来源、已核对/已判定 1、待核对 6；该单条标注与模型一致，不能推断整体准确率。原文和下一条评论由既有分析读取，没有重新调用模型、读取平台或执行互动：[代录与读回核对](../.tmp/user-note-review-summary.json)。本轮无应用代码变更，未重复后台、浏览器或迁移回归。
+
+后续实际核对：用户同意首条评论为询问地区、角色及自身需求不明、暂不能列为意向客户。追加 1 条 `corrected`，仅将原模型的表达不明改为询问；角色、自身需求、相关性与匹配继续保留未知/不足，不继承笔记作者需求。备注保留用户对话确认及 Codex 代录来源，原正文核对与模型分析逐字不变：[评论 1 代录核对](../.tmp/user-comment1-review-summary.json)。首篇当前为已核对/已判定 2（确认 1、纠错 1）、待核对 5；该纠错仅为表达标签，不是确认客户或整体模型准确率。没有调用模型或操作平台，无应用代码变更及新增回归。
+
+首批核对完成：用户对第二条评论选择 C（看不出来，需要更多上下文），追加 `uncertain`、`labels:null`，注明用户选择及 Codex 代录。没有把它强分为建议、服务招揽或自身需求，也不计为模型对错。按编号读回与历史对照通过，前两条核对和原分析不变；首篇 7 个来源中已核对 3、已判定 2（确认 1、纠错 1）、不确定 1、待核对 4：[首批三项汇总](../.tmp/user-first-batch-review-summary.json)。本次无模型/平台调用、无应用代码变更或回归重跑。
+
+按整体方案第 14.2 节保留这三项为有限质量对照，随后再补地区、歧义及更多独立样本。不根据两项已判定样本直接修改默认模型或宣称准确率，未改变模型提示或旧结果。涉及文档：本进度与整体方案的样本状态；实际记录仍在本机 PostgreSQL。
+
+提交/推送：未执行；私有记录及核对报告仍在本机忽略目录。
+
+## 2026-10-24-20：案例评论分支的真实验证准备
+
+目标：按整体方案第 14.2 节，继续验证“案例或服务展示内容 → 评论者自身需求”，补足目前只有业主自身发文的样本范围。
+
+实际完成：通过受限维护入口核对现有搜索四步候选、正文/首层评论八步候选、任务及初筛历史；两候选仍为本机维护者探索、未发布，清单和摘要未改。旧 4 条初筛中，两轮“装修案例”均未保留笔记；两条已有有效阅读属于业主表达自身需求，不能替代案例评论分支。只读复核发现旧案例搜索有标题缺少装修词的候选被规则排除；其中历史来源不符项仍保持无效，不改为可读对象。没有根据标题推断作者是商家或评论者是客户：[本轮准备核对](../.tmp/peer-branch-inspection.json)。
+
+已重新打开既有搜索任务的专用小红书窗口，可见页面检测为 `logged_in`，登录态仍在，无需重新扫码。当前状态为 `awaiting_user / confirmation_required`；已请用户确认当前窗口账号，尚未代填人工确认，也未运行新搜索、读取正文评论或调用模型：[窗口检测状态](../.tmp/peer-branch-current-session.json)。搜索与详情任务使用同一本地账号资料，后续仍按既有会话互斥和当前账号确认执行。
+
+涉及文件：本进度与整体方案第 14.2 节，细化本分支样本范围和通过依据；没有应用代码变更、候选修订、真实人工核对新增或互动写操作。后台 health 实际正常、PostgreSQL；既有回归未因本次准备重复运行，不将此前 159 项计为本轮新验证。
+
+未完成与下一步：等待当前窗口账号确认后，继续有限搜索；优先使用更明确的案例搜索词，若标题规则仍没有保留可读对象，先保留真实失败及漏候选事实，再决定最小筛选修订，不绕过来源绑定。正文须有案例或服务展示依据，评论须各自表达自身需求；未找到符合条件的评论则如实记录，不能因执行完成宣布业务质量通过。详情读取、模型分析和本分支人工核对尚未执行。
+
+提交/推送：本轮未执行；临时工具、真实记录和报告仍保留在本机忽略目录。
+
+## 2026-10-24-21：案例内容搜索通过，等待详情窗口确认
+
+目标：接用户对当前专用账号的明确确认，继续整体方案第 14.2 节的案例评论分支真实样本验证。
+
+实际完成：根据用户本轮对话确认，通过 `browser.ready` 确认既有搜索任务，再由冻结四步候选执行一次“装修公司案例”搜索。新增 `discovery_40adbe10d64f4542b801562e4afb73bc`，关联 `validation_e3877802b61b42f59a4b1b4c1ddc5bd7`，探索验证通过，约 24.075 秒，读到 5 个来源合格的结果，规则保留其中 2 篇 `related_content`。未将标题推定为已确认商家、案例或客户，也没有把未入选的三条等同于真实无关内容：[搜索与断言汇总](../.tmp/peer-branch-search-summary.json)。
+
+验证与会话状态：原 4 条初筛逐字读回不变，搜索候选摘要仍为原冻结值。搜索和详情任务确为同一本地账号资料；当前实现按 task 固定会话和候选执行，不支持跨 task 借用 ready 或交接。因此按既有入口关闭搜索窗口、打开详情任务，检测为 `logged_in`、`confirmation_required`，已请用户确认该窗口账号；没有替用户确认新会话，也未绕过 `ACCOUNT_BUSY` 或 ready 守卫：[详情窗口检测](../.tmp/peer-branch-current-session.json)。
+
+涉及文件：仅本进度及忽略目录中的本轮受限控制工具和证据；没有应用代码、候选、模型配置或提示变更。模型调用新增 0，正文/评论阅读新增 0，人工核对新增 0，无关注、私信或评论写入。临时工具语法和本进度差异检查通过；没有重跑未修改的应用、worker、迁移或浏览器回归，不以既有测试次数冒充本轮结果。
+
+未完成与下一步：详情窗口账号确认后，使用同一冻结八步候选分别读取所保留的两篇笔记，按实际正文及评论判断是否覆盖案例/服务展示与评论者自身需求；随后仅分析已核对来源的已有文字。当前仅完成搜索，不是案例评论分支业务质量通过、客户确认、账号后续观察或正式发布。
+
+提交/推送：本轮未执行；私有记录和临时证据仍在本机忽略目录。
+
+## 2026-10-24-22：新搜索页读取失败及整页有界定位修订
+
+目标：接用户对详情窗口账号的明确确认，继续案例评论分支；对真实页面变化修订学习能力，保留旧候选、失败与验收边界。
+
+真实平台结果：详情会话按本轮用户确认进入 ready，对首篇追加 `reading_64546cf8ec61415192a9668e57600e8f`，关联 `validation_d652ab58cb2248adbb8b1e2504308f1f`。约 **24.140 秒**，填写、回车、集合等待通过，第 4 步旧滚动根未观察到而失败，错误码 `UNOBSERVED_SELECTOR / NOTE_BINDING_MISMATCH`。未进入点击、正文或评论提取，来源绑定未建立，不能将后一码解释成已点开错误笔记。当前为新搜索页结构，已观察普通内容根不再是旧内部滚动容器；当前截图及新观察保留。第二篇未因同一已知缺口重复尝试，模型调用新增 0、人工标注新增 0，无关注、私信或评论写操作：[失败及实际执行前缀](../.tmp/peer-branch-reading-validation-1.json)。原冻结候选摘要读回不变。
+
+实际修订：
+
+- 新增可选 `scroll_scope:"viewport"`，仅用于 `scroll + until_target`；目标范围仍是已观察、唯一、非敏感的普通容器，body/html 不能作根。固定普通根及页面来源，同时固定实际文档滚动对象；按原次数、距离、时间预算记录真实整页位移，目标在根后代中精确匹配。来源/根/文档滚动对象变化、歧义、编号不符、遮挡、未知写请求及边界/预算失败仍停止。缺省容器模式不自动切换。
+- `candidates.create` 新增可选有序 `step_ids`，只冻结本任务已有的 1–30 个唯一真实成功步骤及完整证据；显式路径保存 `source_step_ids`，完整性检查按相同任务原步骤内容核对。未知、异任务、空或重复编号 422 且不创建候选；原全步骤默认行为兼容保留。没有客户端原始清单或步骤覆盖，也未修改旧步骤、候选或数据库 schema。
+- 录制表单新增整页定位选项，历史摘要显示“整页”；动作切换时不向读取泄漏滚动字段。选步组合须独立静态检查、阅读合同核对与真实回放，不继承旧成功。当前证据证明单步来源闭合，不证明重新组合后的时序已通过。
+- 同步 README、维护入口、整体方案第 14.2 节及现有图解。新事实改变原直接读取两篇的顺序：先完成该页面模式修订与新动作取证，再按原有范围复验，不能通过修改旧清单或增大预算记作成功。
+
+工程验证：
+
+- 最终冻结后的单轮完整后台 **164 passed、无跳过**，约 **489.51 秒**，包含 SQLite 与实际专用 PostgreSQL，只有既有 TestClient 弃用提示：[完整后台回归](../.tmp/test-server-viewport-full.log)。此前 SQLite 目标 9 项和数值边界目标 1 项为前阶段，不与完整结果累加。
+- 最终完整工作进程 **69/69**，隔离本机 Edge 页面；包含整页实际移动/零移动、根外同名、消失、边界/超时、歧义/遮挡、来源及根/滚动对象替换、未知写请求、八步来源绑定和错 ID 零移动/零打开，以及整页 DOM 阻塞后的硬截止、真实前缀/PNG、关闭和迟到结果不变。旧容器、媒体、元信息和 EOF 继续覆盖：[完整 worker 回归](../.tmp/worker-regression-tA2yJ5/report.json)。前阶段 7/7、3/3 和预算 3/3 不累加为本轮总数。
+- 前端类型检查及生产构建通过，构建仅既有 chunk 提示。现有离线图解 8 页无脚本错误或节点文字溢出，已查看更新的学习发布页截图；当时文档本地链接 105 项有效：[图解检查](../.tmp/viewport-doc-check.json)。
+
+- 最终单轮隔离 **PostgreSQL + Edge + 本机演示页面 API/UI** 验收通过：[最终界面验收](../.tmp/learning-acceptance-1792855829497/summary.json)。实际 UI 录制整页模式，真实位移 **0→320→640**，随后读取目标；切换读取不携带滚动字段。按两条真实步骤编号冻结新候选、静态通过，再从入口独立回放定位与读取通过；原搜索、动态对象、批次、明确空态、正式模式入口及历史/重启检查继续覆盖，`errors=[]`。这些是本机合成样本，不是本轮小红书正文或评论读取成功。
+- 前两轮界面验收失败保留：`.tmp/learning-acceptance-1792855305036` 的演示页首屏没有建立目标集合观察，校验 422 拒绝，补首屏同集合成员并改用实际观察返回的 CSS；`.tmp/learning-acceptance-1792855586045` 仅选择滚动一步，固定校验因没有读取输出拒绝，补实际读取后选两步并独立回放。均为夹具/验收准备不足，没有放宽产品校验；不将前轮局部通过替代最终通过。
+
+涉及范围：后端动作/候选输入、学习与阅读合同及新目标测试；worker 契约、执行和本机回归；后台动作类型、表单和摘要；本机界面验收夹具及既有文档。参考工程与共享工作区原有改动保留。模型配置、提示、真实原文和人工核对结论未改。
+
+加载与当前状态：已通过既有入口关闭旧详情窗口，再重启本任务持有的开发服务加载修订。实际 API/前端代理 health 正常、首页 200，PostgreSQL；修改/新增源码 82 份及构建产物 3 份对实际模型 Key 精确扫描 0 命中，`.env` 仍被忽略，最终本地文档链接 112 项有效：[本机交付核对](../.tmp/viewport-final-qa.json)。未重复迁移、检索扩展、模型评测或 macOS 验收。
+
+为新页面另建干净的 `learn_dc9059a8f4fb4ab5ba8e985da98b034c`（整页定位与案例评论读取），沿用原维护者、平台及本地账号资料，样本参数取本次已保留笔记，不修改原任务参数或步骤。新窗口检测为已登录、`confirmation_required`，已请用户确认更新后打开的窗口，尚未代填新会话确认、录制新真实动作或创建真实修订候选：[新学习会话状态](../.tmp/peer-branch-relearn-session.json)。
+
+未完成与下一步：按整体方案第 14.2 节，在该会话确认后重新观察和记录页面模式，冻结新候选并独立校验/有限回放；然后继续两篇来源核对和已有文字分析。新页面若目标重排、消失或预算内未找到仍停止并保留失败；当前没有真实案例正文/评论需求样本或业务质量通过结论。新候选真实平台复验、账号延后反馈、独立业务读回、双端交付与正式发布均未完成。
+
+提交/推送：本轮未执行；真实记录、账号资料及测试报告仍保留本机忽略目录。
+
+## 2026-10-25-01：整页链路录制、分页阶段策略与新八步候选
+
+目标：接用户“账号正确，继续学习”的确认，在整体方案第 14.2 节继续案例评论分支，重新取证并验证搜索到正文/首层评论。
+
+真实录制：当前学习任务按本轮对话确认进入 ready。填写、回车和集合等待后，首次整页定位实际移动 **0→320**，页面自然产生搜索分页请求，被本地通用只读策略拒绝，错误 `WRITE_REQUEST_BLOCKED`；失败尝试及前后截图保留，不计成功步骤，不据此认定平台异常提醒或账号降权。核对失败后实际页面及新增观察，目标已完整可见，再记录零移动定位。随后唯一链接核对来源编号、点击、等待及正文提取成功；正文是服务提供表达，不能据此认定作者真实身份。
+
+本任务共录制 11 条成功步骤，其中包含额外来源核对与两次用于观察的评论容器滚动。末次评论提取取得 **2 条完整文字、2 批**，`coverage:bounded / truncated:true / stop_reason:time_budget`；不完整行跳过计数为 5，属于累计观察次数，不等于另有 5 条唯一漏读。只处理首层文字，作者子回复未混入，本新合同没有媒体覆盖：[评论提取及批次证据](../.tmp/peer-relearn-action-11.json)。询问联系方式不足以确认评论者自身装修需求或项目地区，未将页面全量文本补入该输出。
+
+新版本：从真实步骤 **1、2、3、4、6、7、8、11** 有序冻结 `candidate_1500902c9a0e4a2090c9a3e524ccfe72`，摘要 `7bf35005d0f9c5a169d210c7053696e0e3b0eb05e40557f6f8518f08ca30008b`，独立静态验证 `validation_74dc312ff4d2414281f0317b10ae3ee4` 通过：[冻结候选](../.tmp/peer-relearn-candidate.json)、[静态检查](../.tmp/peer-relearn-candidate-check.json)。没有修改旧候选。新组合不含录制中的两次额外评论滚动，须从入口独立验证其前置状态；零移动录制及静态通过不能证明真实分页或完整重放通过。
+
+实际修复：新增 `xhs-search-scroll-experimental-v1`，仅对官网精确搜索页、已观察唯一普通根、显式整页文字目标定位生效；私有绑定当前完整页面地址与签发时间、15 秒内、当前主框架，只允许原有 collect、APM fetch 和精确搜索分页 xhr 三条规则，动作结束即撤销。没有放宽其他搜索/笔记/通用读取阶段，不主动请求接口，不涉及绕过验证。后端清洗只保留该版本对应的三个规则标签，不落盘原始请求头、正文或完整查询。涉及 `tools/learning/platform-policy.mjs`、worker 接线、后端 `worker.py` 及目标测试；同步整体方案、维护入口和原图解说明。共享工作区其他改动保留。
+
+本轮工程验证：纯策略 **650 断言通过、真实请求 0**；隔离本机 Edge 整页目标 **3/3**：[目标报告](../.tmp/worker-regression-533s9y/report.json)；后端安全元信息纯清洗 **2 passed、12 deselected**，约 2.19 秒，仅既有 TestClient 提示：[输出](../.tmp/test-search-scroll-metadata.log)。Python 语法与局部差异检查通过。上一阶段 164 项后台、69 项 worker、迁移、前端构建及双端未在本轮重跑，不累加为本轮计数。
+
+加载状态：通过维护入口关闭旧会话，再停止并重启本任务持有的服务加载修复；同一学习任务和账号资料重新打开，仍检测为 `logged_in / confirmation_required`，无需重新扫码。当时等待用户明确确认，未沿用旧窗口的 ready：[重开会话](../.tmp/peer-relearn-session-after-policy-update.json)。随后用户明确回复“账号正确，继续验证”，经维护入口确认后执行下述独立回放。没有关注、私信、评论写入。
+
+独立回放结果：新增 `reading_c1a5a8401dd7426ea6f7316a8dd10587`，关联 `validation_9e7e55cd315441b7b164a6bdd3fcb098`。约 85.404 秒（工作进程内），搜索至正文前七步通过，整页目标已可见、实际零移动；链接编号、当前编号、标题与来源核对通过，保留正文 1 条。第八步评论提取失败，阅读为 **partial**、`comments:null`，不是确认空评论；没有把录制时两条评论补进业务阅读：[独立回放与断言](../.tmp/peer-relearn-reading-validation.json)、[读回汇总](../.tmp/peer-relearn-final-summary.json)。原候选摘要和本初筛此前 1 条失败阅读读回不变，真实分析新增 0、人工标注新增 0。
+
+失败定位：本次仅一条已知 collect 遥测 POST/XHR 被阻止，发生于评论步骤开始约 22.5 秒后；此前同类型已有 `xhs-readonly-ui-experimental-v1` 允许标记。该步批次取证约 **20.397 秒**、实际执行约 2.479 秒、失败取证约 15.768 秒，整体 38.779 秒。与既有策略/批次 15 秒边界被截图跨越高度吻合，但日志未直接保存签发/到期及拒因，不能断言是唯一原因。不是新增分页请求规则缺失，也没有本次关注/私信/评论写证据；不扩规则、不延长 15 秒，不自动重试或继续第二篇。当前窗口仍已登录且 ready，原失败、实际批次截图及部分正文保留。
+
+最终本机核对：API、前端代理及首页 200，PostgreSQL；修改/新增源码 82 份、既有构建产物 3 份对真实模型 Key 精确扫描 0 命中，`.env` 仍忽略：[核对报告](../.tmp/search-scroll-final-qa.json)。图解 8 页无脚本错误及节点溢出、本地链接 122 项有效，已查看当前真实失败截图和图解截图：[文档检查](../.tmp/search-scroll-doc-check.json)。构建产物扫描不等于本轮重建前端。
+
+未完成与下一步：按整体方案第 14.2 节，优先核对并优化批次取证的实际成本，补齐 15 秒批次截止与请求策略的生命周期及真实部分结果回传，再对新修订有限复验；保持规则、来源、次数和总预算限制。尚未取得本分支可用业务评论，不调用模型冒充已分析评论，也不将服务正文当作客户需求。第二篇、本分支质量、真实分页移动、账号延后反馈、独立业务读回、桌面及 macOS 交付仍未完成。
+
+提交/推送：本轮未执行；账号资料、真实原文、截图及临时报告仅在本机忽略目录。
+
+## 2026-10-25-02：评论取证优化、批次硬截止与完成前缀保存
+
+目标：按整体方案第 14.2 节修复上轮评论取证与 15 秒窗口的交叉问题，再复验同一候选；不延长窗口、扩大请求规则或修改旧失败。
+
+实际完成：
+
+- `describePage` 的单次同步 DOM 求值内增加节点样式、几何、敏感判断、可见性、定位辅助和两种原始文本遍历缓存；每次观察重新创建，不跨页面、滚动或调用。完整观察、全文/视口文字、筛选排序、上限、脱敏及截图掩码保持原语义，没有缩为只拍评论区域。
+- 批次读取、滚动及取证纳入硬截止，不晚于已签发策略到期，最多 15 秒内预留最多 2 秒关闭。截止撤销策略/ready、关闭该浏览器上下文，返回 `BATCH_BUDGET`；总截止先到保留 `VERIFY_BUDGET`。截图完成前后均检查会话，阻止迟到描述/截图追加为成功。
+- 每批字段、业务 ID 去重及计数先暂存；实际截图完成、来源/固定根/登录/请求复查及时间核验都通过后才提交。截止时仅保留已提交批次的深复制前缀及对应 PNG，标记截断与 `time_budget`，验证仍失败、业务阅读仍为部分完成；首批未完成不补评论。实际失败截图可保留，但其未核对字段不冒充完成结果。
+- 截图等待期间若未知请求已被拦截再到截止，同步保留 `WRITE_REQUEST_BLOCKED + BATCH_BUDGET`，不提供评论前缀，避免预算错误掩盖请求失败。录制和试跑都只对真实 `session_closed:true` 承认关闭并撤销后台 ready，字符串或其他伪值不能关闭；不自动重试或恢复会话。
+- 新增观察等价、批次截止和后台关闭/部分保存目标测试，同步维护入口、整体方案及原图解。数据库 schema、模型配置、提示及真实原文/人工结论未改；共享工作区其他改动保留。
+
+工程验证：
+
+- 本机 Edge **20/20 深等价比较**，包含完整观察、限定定位、遮挡、敏感祖先、样式/滚动/删除重建跨调用刷新、媒体事实、文字截断和输出上限：[等价报告](../.tmp/observation-cache-1792901272594/report.json)。合成大页观察首轮约 258→54 毫秒，仅为合成样本，不能据此承诺真实小红书耗时。一次扩测断言未归一化空格的前序失败保留，未因该失败修改产品比较结果。
+- 最终复合边界修复后，单轮本机 Edge 批次目标 **12/12**：[截止报告](../.tmp/batch-deadline-JvRmJa/report.json)。实际挂起字体截图证明首批截止无评论、后批截止仅保留首批 2 条及真实 PNG，关闭后迟到回调不改变结果；总截止优先、来源/根变化、未知请求、未知请求与截图截止并发、资料重开及内部预算不超上限均覆盖。平台/模型调用 0、未知写请求到本机夹具 0。前序 11 项结果不累加；初轮夹具误用敏感 ID 的失败证据 `.tmp/batch-deadline-Q20GGy` 保留。
+- 后台最终新文件单轮 **11 passed**、约 72.21 秒，SQLite、专用 PostgreSQL 和 RPC：[后台目标输出](../.tmp/test-server-batch-budget-closed-v3.log)。验证合法批次前缀、正文、来源、证据和计时保存为 partial；仅真实布尔关闭撤 ready；下次请求不自动调用 worker；原候选/初筛/阅读/验证逐字不变。前两轮扩展测试因夹具缺少搜索语义、额外要求候选状态暂停而失败的报告保留，只修测试准备/多余断言，未放宽产品。
+- 本轮既有完整 worker **69/69**：[既有完整回归](../.tmp/worker-regression-ZDqvP2/report.json)。该轮在最终“未知请求与截止并发”补丁前启动；最终新增差异由上述 12 项另验，不冒称最终冻结后的一次全量，也不与各阶段计数累加。没有重跑未变的后台全量、数据库迁移、前端构建、检索扩展或 macOS 验收。
+
+涉及文件：`tools/learning/browser-worker.mjs`、`apps/server/worker.py`、`apps/server/learning.py`，新增三个目标测试文件 `test-observation-cache.mjs`、`test-batch-deadline.mjs`、`test_batch_budget_closed.py`，及既有文档。Python/JS 语法和差异检查通过；无提交或推送。
+
+加载与真实状态：经维护入口关闭原会话，重启本任务持有的服务加载修复；同一学习任务、同一账号资料重开，检测仍为 `logged_in / confirmation_required`，无需扫码，等待新窗口账号确认：[重开会话](../.tmp/peer-budget-session-after-budget-update.json)。尚未执行修复后的真实搜索/评论回放，新增业务阅读/模型分析/人工标注均为 0；上一轮部分阅读及其候选不变，没有关注、私信、回复或评论写入。
+
+最终本机核对：API/前端代理正常、首页 200、PostgreSQL；修改/新增源码 85 份及既有构建产物 3 份对真实模型 Key 精确扫描 0 命中，`.env` 保持忽略：[核对报告](../.tmp/batch-budget-final-qa.json)。现有图解 8 页无脚本错误及节点溢出，文档本地链接检查通过：[图解检查](../.tmp/batch-budget-doc-check.json)。本轮没有重建前端；产物扫描不代表重新构建。新语法、差异与报告路径检查通过。
+
+未完成与下一步：按整体方案第 14.2 节，在当前窗口确认后用同一冻结候选执行一次来源绑定阅读，比较真实批次与取证耗时，按实际完整/部分/失败保存；成功取得业务评论后才分析其文字，再决定第二篇。真实页面性能、案例评论分支业务质量、真实分页移动、账号延后反馈、独立读回、桌面及正式发布仍未通过。

+观察与边界：已完成两步的后置取证分别约 **304 / 250 毫秒**；这只是本样本已完成步骤，不把 8.141 秒与此前执行到正文后的 85.404 秒当作同范围性能比较。回车后观察尚无 `#global a.title` 集合，后来失败截图已有正常结果卡；截图可见结果不追溯改写失败，也不确认账号延后状态。当前失败有 collect、另一 APM 发送类型及安全状态请求被阻，只有安全请求摘要，无请求头/正文/凭据；不能据请求名字认定平台发出非真人提醒或账号降权，更不新增放行规则。
+
+离线定位：等待步骤的 `observed` 固定取自该步前的最新观察。若该观察没有目标集合，`selectorObserved` 始终不满足，集合后来出现也不能建立现有只读策略；若旧观察已有集合而当前暂空，则后续非空才可能建立，二者不混同。此前先进入 automating 再尝试建策略，会在尚无可用策略时阻断页面自身辅助通信。新取证更快时暴露了原录制未覆盖的加载前置状态，不能用固定延迟或借用上一搜索权限掩盖。
+
+本轮最小修复：新增 `preflightReadonlyWait`，仅官网 wait 在进入自动化前按原观察、实际普通根和原规则预检；无法建立现有策略时明确 `READONLY_WAIT_NOT_READY` 并保存失败证据，不执行自动化等待。敏感对象保持 `SENSITIVE_OUTPUT`，非官网示例和原 body 例外不扩展，策略版本、规则、窗口与安全请求限制不改。涉及 `tools/learning/browser-worker.mjs` 及独立目标测试；同步维护入口、整体方案与原图解，没有数据库或 UI 协议变更。
+
+目标验证：独立 `test-wait-preflight.mjs` 单轮 **92 断言**通过，含 20 个官网元数据纯 helper 场景；仅原 collect xhr / APM fetch 允许，APM xhr、安全状态、搜索及未知请求继续拒绝，撤销/伪造及调用者状态不变。另一次真实本机 Edge 循环地址夹具从未观察到的零项集合等到自然出现 2 项，通过并保存实际 PNG；官网浏览器导航、真实平台/模型/API 调用均为 0，夹具只有 2 次 GET、写入 0：[目标报告](../.tmp/wait-preflight-DZvvCp/summary.json)。这是纯策略边界及本机等待兼容验证，不是官网等待前置的端到端或真实加载过渡已学会。语法和差异检查通过，未重跑前阶段完整 worker、后台、迁移或前端构建。
+
+历史与当前状态：原候选摘要及本初筛此前两条失败/部分阅读读回不变，没有新增候选、录制步骤、模型分析或人工标注；第二篇未运行，无关注、私信、评论写入。当前专用窗口仍已登录且 ready。本轮前置修复尚未重启加载，避免为未完成的新加载过渡反复关闭窗口和要求账号确认；源码已修改不冒称当前进程已使用新检查。
+
+本机收尾：API/前端代理正常、首页 200、PostgreSQL；修改/新增源码 86 份与既有产物 3 份对实际模型 Key 精确扫描 0 命中，`.env` 仍忽略：[核对报告](../.tmp/wait-preflight-final-qa.json)。图解 8 页无脚本错误及节点溢出、本地链接检查通过，已查看当前真实失败截图及更新图解：[文档检查](../.tmp/wait-preflight-doc-check.json)。旧构建产物仅扫描，未重复构建。
+
+未完成与下一步：按整体方案第 14.2 节先依据实际回车后观察和结果出现后的证据，学习普通容器内加载过渡的前置及结束条件；需要新字段或范围时先定义来源、集合归属、根变更/超时中断及用例，再实现、冻结独立修订和有限回放。当前没有取得本分支可分析业务评论，不自动重试、跳过等待或扩大请求规则。真实评论修复效果、业务质量、真实分页移动、账号延后反馈、独立读回与交付仍未通过。
+
+提交/推送：未执行；真实记录、原文和截图保留本机忽略目录。
+
+## 2026-10-25-04：显式普通根范围等待、证据合同与隔离验证
+
+目标：继续整体方案第 14.2 节，解决搜索回车后最新观察只有普通容器、结果集合尚未出现时的加载过渡；不改变旧候选、失败或请求规则。
+
+实际完成：新增可选 `wait_scope`，限定可见且显式数量的集合等待。根须是最新观察的唯一、可见、非敏感普通读取容器；固定实际根对象及完整页面地址，只在根内查询后代，范围外同名对象不计数。目标可暂为零；根替换、来源变化、敏感/交互区域、超过100项及条件消失均停止。冻结引用实际根的观察证据，不补造缺失集合。旧未声明范围步骤及七/八步阅读合同保持兼容，无数据库 schema 变更。
+
+执行层轮询、根/集合与登录检查纳入等待截止，最长15秒且不晚于原策略到期，在内部预留最多2秒关闭；到期撤销策略及 ready，返回 `WAIT_TIMEOUT`，实际关闭确认才报 `session_closed:true`。后置完整观察/PNG 在撤销自动化和策略后执行，保留原截图限制与外层总预算；总截止先到仍为 `VERIFY_BUDGET`。后置再次核对同一根及可见、视口内、非忙碌数量，变化不记成功。官网仍只用原 collect xhr / APM fetch 两条辅助规则，不允许 APM xhr、安全或搜索请求借用权限。
+
+后台表单仅在可见集合等待显示可选范围，维护者显式选择，不默认代选；切换动作/状态/数量或最新观察根失效时清空，历史显示范围。服务端重新核对最新及实际动作前根，冻结根证据。涉及 `browser-worker.mjs`、`action-contract.mjs`、`learning_contracts.py`、`learning.py`、四个后台类型/表单/页面/摘要文件及两份新目标测试；同步整体方案、README、维护入口及既有图解。共享工作区原有改动保留。
+
+最终单轮验证：
+
+- 本机隔离 Edge **20/20 组、235 断言**：[执行层报告](../.tmp/scoped-wait-nOnfuj/report.json)。覆盖零项到集合、前缀/相对 CSS、后续读取、根外忽略、根/来源变化、敏感与数量、未知 POST、旧等待。实际挂起 DOM 返回 `WAIT_TIMEOUT` 并确认关闭；实际字体截图挂起由外层 `VERIFY_BUDGET` 中断，已得 PNG 和迟到不变性通过。官网仅纯元数据边界，平台导航/模型/应用 API 调用均为0，未知写请求到夹具0；不是真实小红书验收。
+- 后台新目标 **14 passed、无跳过，91.64秒**：[后台输出](../.tmp/test-server-scoped-wait.log)，包含 SQLite 和真实专用 PostgreSQL 随机隔离 schema，验证根证据、冻结、旧记录不变及七/八步兼容；未操作开发库或平台。前阶段8项不累加。
+- TypeScript 检查及前端生产构建通过，构建约37.36秒，仅既有 chunk 提示；本机隔离界面 **7项通过、页面错误0**：[界面报告](../.tmp/scoped-wait-ui-1792903347781/summary.json)，未访问真实平台或调用模型。
+
+前序夹具失败报告保留：根替换竞态已补同步固定根检查；未知 POST 改以实际集合轮询信号触发，避免在动作前取证阶段提前发送；旧等待夹具不再要求新范围查询；本机短等待的关闭预留过短，测试预算改为仍低于产品上限的1200/2000毫秒。未将前轮局部结果累加，也未因夹具不稳定放宽生产规则。独立只读集成复核未发现新增实质问题；语法及局部差异检查通过，旧阶段全量、迁移、检索扩展和 macOS 未重跑。
+
+加载与真实状态：通过受限维护入口关闭原窗口，停止本任务持有的开发服务并确认端口释放，再重启加载前置和范围等待修复。同一任务/账号资料重开，检测仍为 `logged_in / confirmation_required`，无需扫码；已请求确认当前新窗口账号，尚未代填确认、记录新搜索/范围等待或创建新候选/阅读：[重开状态](../.tmp/peer-scoped-open.json)。实际仍为11条旧成功步骤和1个旧候选，新增真实业务阅读/模型分析/人工核对均0，第二篇未运行，无关注、私信或评论写入。旧初筛、候选和三条失败/部分阅读已保存当前基线，不覆盖历史：[本轮基线](../.tmp/peer-scoped-baseline.json)。
+
+本机服务核对：API/前端代理正常、首页200、PostgreSQL；修改/新增源码88份及本轮构建产物3份对实际模型 Key 精确扫描0命中，`.env`仍忽略：[交付核对](../.tmp/scoped-wait-final-qa.json)。图解8页无脚本错误或节点溢出，本地链接140项有效，并已查看更新图解截图：[文档核对](../.tmp/scoped-wait-doc-check.json)。
+
+未完成与下一步：依整体方案第 14.2 节，新窗口确认后以一次新的实际搜索录制范围等待，冻结独立八步修订并静态检查，再对首篇执行一次来源绑定完整回放。只对真实取得且来源核对通过的正文/评论分析；第二篇、业务质量、真实分页、账号延后反馈、独立读回及桌面交付仍未完成。不自动重试或扩请求规则。
+
+提交/推送：本轮未执行；真实账本、浏览器资料、原文、截图及报告保留本机忽略目录。
+
+## 2026-10-25-05：范围等待实录、新八步冻结及一次真实回放
+
+目标：接用户“账号正确，继续”，确认新窗口后按第14.2节录制新搜索等待，冻结修订并执行一次完整来源绑定阅读。
+
+实际录制：通过受限维护入口确认当前会话，重新观察首页。以任务参数 `keyword` 完成填写、回车及显式 `wait_scope:#global` 集合等待，新增成功步骤12、13、14，未修改旧11步。回车后观察有普通根、无结果集合，随后等待动作前已出现20个标题，等待成功并完成前后取证；不能称本次实际轮询从零项等到了20项：[回车记录](../.tmp/peer-scoped-action-13.json)、[范围等待](../.tmp/peer-scoped-action-14.json)。准备时首次填写请求同时传值和参数名，被422输入校验拒绝、未执行浏览器动作；改为仅引用已有任务参数后成功，没有调整产品校验。
+
+新版本：按真实步骤12、13、14、4、6、7、8、11冻结 `candidate_52d71f3e4b244830a5e328b24bab8796`，摘要 `89871dd9538b2cadee7f9de5c6e58584de9b8e62a82dfcd3a094e8023da2f320`。新 `validation_8b115276eee246879e2d798857eafdf6` 静态通过：[新候选](../.tmp/peer-scoped-candidate.json)、[静态检查](../.tmp/peer-scoped-check.json)。离线独立复核步骤顺序、阅读合同、摘要和18项冻结证据一致。仍包含旧录制的零移动定位和评论合同，不能借静态通过继承运行成功。
+
+一次独立真实回放：新增 `reading_0375f7b467fc4c0da2037cca099b7fa8`，关联 `validation_f05756c9ce61401a8b1d1fcc5aa76961`。工作进程约8.174秒，填写/回车通过，第3步范围等待失败，错误 `WRITE_REQUEST_BLOCKED / NOTE_BINDING_MISMATCH`。未执行定位或点击，来源绑定尚未建立，后一码不表示已打开错误笔记；正文/评论均无可用结果，阅读为 **failed**，不能分析：[真实验证](../.tmp/peer-scoped-validation.json)、[阅读](../.tmp/peer-scoped-reading.json)、[读回汇总](../.tmp/peer-scoped-summary.json)。未自动重试或执行第二篇。
+
+失败已分清：最新观察有普通根但无结果集合，执行时已成功建立 `xhs-readonly-ui-experimental-v1`，collect xhr 与 APM fetch 具有实际允许标记，说明新等待前置已生效。该阶段另有安全状态请求及 APM xhr 被本地规则拦截；失败取证时已有20个结果标题。不是等待超时、根缺失或取证跨15秒窗口，也不能仅据请求摘要认定平台已发非真人提醒、账号降权或这些接口无副作用。只保存既有安全元数据，没有请求头/正文/凭据，未放行安全请求或扩大规则：[加载及请求证据](../.tmp/peer-scoped-loading-evidence.json)。已查看等待成功与回放失败的实际截图。
+
+历史与边界：当前任务共14条成功步骤、2个候选；旧候选完整内容及此前三条失败/部分阅读逐字读回不变。当前窗口仍已登录且ready，新增模型分析及人工核对0；没有关注、私信、评论或回复写入。已同步当前进度、整体方案、README及图解；本轮没有修改产品代码或重跑前轮工程套件，不累加前轮测试数。当前的可见搜索页面不替代账号延后反馈。
+
+收尾核对：API/前端代理正常、首页200，数据库为PostgreSQL；修改/新增源码88份及构建产物3份对实际配置Key精确扫描0命中，`.env`仍忽略：[本机检查](../.tmp/scoped-replay-final-qa.json)。图解8页无脚本错误或节点溢出，文档本地链接149项有效：[图解与链接检查](../.tmp/scoped-replay-doc-check.json)。这些不是重跑前端构建或真实平台通过。
+
+未完成与下一步：按整体方案第14.2节，先核对实际请求边界与适用范围，区分本地阻断、页面提醒、加载和来源条件，再确定兼容设计与独立验证；保留安全/未知请求中断及实验状态。当前完整阅读仍未通过，案例评论分支需求质量、真实分页、账号后续反馈、独立读回与双端交付未完成。尚无本分支有效评论可供人工核对，不要求用户重复登录或标注不存在的内容。

+
+## 2026-10-25-06：请求拒因、失败诊断贯通与兼容边界核对
+
+目标：接用户“继续”，按第14.2节核对上轮本地请求阻断。先补可追溯的拒因及显示，不通过重复运行账号或放开安全请求来掩盖兼容问题。
+
+实际完成：
+
+- `platform-policy.mjs` 新增同源的纯决策结果，原 matcher 复用同一判断。记录15种固定本地拒因，包括无策略、失效/过期、范围不符、地址变化、发送类型不符等；四类策略7/8/2/3条原规则和既有到期差异保留，不增加放行。安全状态路径只说明不在当前规则，不据路径确认业务副作用或平台提醒。
+- 动作失败及实际 blocked 请求摘要可带 `policy_reason`、已签发的 `active_policy_version`；仅资源类型不符时可带受限 `expected_resource_types`。摘要最多12类、观察最多30条，总数另留，仍不记录查询、头、正文或凭据。允许请求的原版本/规则标记不变。
+- 工作进程按真实失败位置追加 `failure_diagnostics`，包括步位、动作、实际错误码及受限诊断；正常失败深复制，整轮截止同步快照并关闭，不额外等待诊断或接受迟到变化，成功不返回该字段。服务端二次核对失败布尔值、位置/动作及实际错误码，清洗后存入新验证及关联阅读；非法诊断丢弃但不改变原失败，旧记录不补造，无schema变更。
+- 后台验证、阅读与动作失败复用请求详情：概要显示失败步位、动作、阶段及阻止总数，详情默认折叠，展示固定中文拒因、策略及接受类型。缺失原因或旧记录显示未记录，不从通用错误码推断平台封号、真实写入或等待超时；无放开规则/自动重试入口，窄屏可用。
+
+涉及文件：`tools/learning/platform-policy.mjs`、`browser-worker.mjs`，后端 `worker.py/learning.py/reading.py`，后台类型、动作失败组件、新验证诊断组件及验证/阅读页面；新增两份目标测试，既有 worker 隐私白名单断言只新增固定拒因字段并验证其值，继续排除私密字段。共享工作区已有改动、原候选/失败阅读、模型配置及人工结论保留。
+
+最终目标验证：
+
+- 单轮 **8组、7567断言**：[执行层目标](../.tmp/request-diagnostics-aDDUCX/report.json)。独立旧matcher对照3648种组合，四策略允许集合、规则数及到期边界一致；只用官网元数据纯判断，不导航官网。真实本机Edge验证动作及回放诊断、16次拒绝/12类摘要上限、真实PNG及私密哨兵排除，未知POST到夹具0。挂起DOM与真实字体截图分别约3303/3296毫秒由3500毫秒总截止取消，实际关闭、阶段准确且迟到结果不变。平台、应用API、模型调用均0；前阶段纯目标不累加。
+- 后台目标单轮 **12 passed、无跳过，52.97秒**：[后台目标](../.tmp/test-server-request-diagnostics.log)，含新10项与既有允许元数据纯回归2项，覆盖SQLite和真实专用PostgreSQL随机隔离schema；使用FakeWorker，不访问真实平台。合法failed/partial阅读复制、成功拒带、缺失兼容及原候选/初筛/阅读/验证逐字不变均通过，首阶段7项不累加。
+- 实际Node工作进程输出再经Python清洗边界核对 **4项通过**：[跨语言读回](../.tmp/request-diagnostic-worker-bridge.json)，含请求失败、DOM/截图总截止及成功无失败字段；无数据库、平台或模型请求，不冒称完整应用API端到端。
+- TypeScript检查、生产构建通过，仅既有chunk提示。本机隔离Edge界面 **10项通过**：[界面目标](../.tmp/request-diagnostic-ui-1792905535311/summary.json)，覆盖新旧验证/阅读/动作、15类拒因、秘密字段排除、无隐式重试、零阻止不造阻断以及390px布局；页面错误/真实后台/平台/模型请求0，已查看桌面诊断截图。前序夹具路径笔误及检查范围过宽的失败保留，只修临时测试，不放宽产品。
+- 产品冻结后，既有完整worker单轮 **69/69通过**：[完整回归](../.tmp/worker-regression-rMYZDP/report.json)，使用Edge和本机隔离页面，覆盖更新后的严格五字段隐私断言、正常/未知请求、来源/根变化、七八步阅读、容器/整页定位、批次、空态、媒体、总截止与实际截图/DOM中断、资料目录及EOF生命周期。没有真实平台、应用API或模型调用，不与新8组或旧阶段计数累加。
+
+收尾核对：API/前端代理正常、首页200、PostgreSQL，实例与上轮一致，未重启生产服务；修改/新增源码91份及本轮构建产物3份对实际模型Key精确扫描0命中，`.env`仍忽略：[本机核对](../.tmp/request-diagnostic-final-qa.json)。图解8页无脚本错误或节点溢出，本地文档链接通过：[图解检查](../.tmp/request-diagnostic-doc-check.json)。已查看桌面及390px诊断截图，语法和局部差异检查通过。
+
+边界与加载：当前保护仅在动作自动化窗口生效；动作结束或失败后，网页恢复普通通信，不能把一次阻断说成后续同类流量仍持续被拦。未借改变标志/延迟/旁路来获得运行通过，也未新增审批或反复确认账号流程。本轮没有关闭或重开现有窗口，后端及工作进程尚未重启加载新诊断。受限入口只读核对仍为已登录/ready、14步/2候选：[当前会话](../.tmp/request-diagnostic-session-status.json)。新增真实录制、阅读、模型分析、人工核对均0，第二篇未运行；上轮真实失败仍是原失败，不能补写新的拒因到旧记录。
+
+未完成与下一步：依整体方案第14.2节，继续明确平台正常网页通信与任务主动业务动作的兼容边界，再确定适用范围和独立验证；本轮完善的是诊断，尚未解决真实请求兼容或通过完整阅读。新诊断待下次受控重启后参与真实记录，当前不反复拿账号试错。案例评论业务质量、账号后续反馈、真实分页、独立读回、桌面与正式发布仍未完成。

+
+## 2026-10-25-07：统一 Playwright 执行配置、原生页面通信与全新实录准备
+
+目标：接用户确认“沿用 Playwright 固定执行，学习端和桌面共用”。解决旧模式将部分官网正常通信按请求规则阻断的兼容问题；新模式须全新学习、冻结和验证，不将旧步骤改名后宣称通过。
+
+实际实现：
+
+- 新增显式 `playwright-xhs-native-ui-v1`，固定三字段执行合同为 `engine:playwright / action_policy:xhs-bounded-readonly-v1 / network_policy:xhs-page-native-v1`。任务声明、实际会话、观察、动作、冻结候选及实际验证分别记录来源；后台核对有效实际回显后才接纳。验证开始导航前核对配置，禁止跨配置回放、额外合同字段及调用者覆盖。静态校验不冒称实际执行，阅读和初筛只沿用实际验证环境，不改写旧来源。
+- 原生模式将主动动作限制在官网已观察且唯一可用的搜索输入/Enter、固定实际笔记链接，以及普通、不可编辑、非交互根内的有界读取、等待和滚动；拒绝表单提交目标、未知/下载链接、交互祖先和错误角色。搜索完成核对对应关键词结果页，笔记点击核对固定编号，其余动作核对完整来源。没有开放直接 API、任意 JavaScript 或自主 Agent 执行。
+- `xhs-page-native-v1` 允许上述动作自然产生的第一方 HTTPS 主框架 `xhr/fetch POST` 通信，包括网页自身安全状态通信；并不按接口名称伪称无业务副作用。策略在进入自动化前签发，绑定当前页面及明确允许的搜索/笔记过渡，最长15秒，不续签。非第一方、子框架、其他写方法或来源变化仍拒绝，原批次/总截止、取证和对象绑定继续生效。legacy 四类精确请求策略保持原规则，不自动迁入新模式。
+- 该边界约束维护工具可执行的页面动作，不是完整网络沙箱，也不保证网页通信无状态变化或平台永不提示异常。普通页面通信在动作结束后恢复，Service Worker 等覆盖仍有实际限制；没有新增指纹伪装、检测绕过或失败自动重试。
+- PostgreSQL/SQLite schema 10 为任务追加可空执行配置，旧任务 DTO 省略空值，原候选/证据不回填；原 SQLite 备份迁入 PostgreSQL 路径兼容。后台小红书新任务默认新配置，可显式保留 legacy；切换平台清空配置。界面分别展示任务声明、实际会话、冻结合同、实际验证与业务阅读/初筛，不推断缺失值。
+
+涉及文件：`tools/learning/execution-profile.mjs`、`platform-policy.mjs`、`browser-worker.mjs`；服务端 `main.py/learning_contracts.py/learning.py/worker.py/db.py/postgres.sql/reading.py/discovery.py`；后台类型、两份新配置组件及任务/候选/验证/初筛页面；新增执行层与后台目标测试。同步 README、维护入口、整体方案及原图解，原共享改动保留。
+
+冻结后验证，分别统计不累加：
+
+- 新配置目标 **16组、809断言通过**：[执行层报告](../.tmp/native-ui-profile-7RbFQ7/report.json)。含36个真实本机 Edge DOM样本、纯官网元数据策略矩阵、最终来源核对及实际 legacy worker 字段省略/跨配置导航前拒绝。实际 DOM夹具只有1次GET、外域尝试0；使用真实PNG，已查看。不导航真实平台、不调用应用API或模型；这是合同与隔离浏览器边界验证，尚非新模式整条真实链路通过。
+- 既有完整 worker **69/69通过**：[回归报告](../.tmp/worker-regression-r6Khjn/report.json)。在本轮生产代码冻结后单轮执行，Edge与本机隔离页面，包含旧七/八步、批次、来源/根变化、总截止、实际取证和会话生命周期；平台/应用API/模型调用0。前阶段69项不累加。
+- 后台 **13 passed、无跳过，88.09秒**：[后台目标](../.tmp/test-execution-profile-final.log)。使用 FakeWorker，覆盖SQLite和真实专用 PostgreSQL 随机隔离schema、schema10幂等升级、旧SQLite备份迁入空PostgreSQL后原摘要/manifest保持不变、实际回显与候选证据拒绝、旧初筛/新阅读分别保留来源。未操作开发库或平台；共享旧SQLite只读核对未升级：[核对记录](../.tmp/profile-shared-sqlite-readonly-check.json)。
+- TypeScript检查和生产构建通过，构建约1.43秒，仅既有chunk提示。隔离 Edge 界面 **11项通过**：[界面报告](../.tmp/execution-profile-ui-1792908594379/summary.json)。23次内存模拟请求/4次模拟创建，真实后台/平台/模型请求0，页面错误和意外请求0，已查看桌面与390px截图。前序夹具定位问题只修临时测试，未因此放宽产品规则。
+
+加载与真实状态：通过受限维护入口关闭旧窗口，停止本任务持有服务并确认8810/5179释放，再重启加载新代码及schema10。新增 `learn_cbf78367730748b59da7cc0c2ec6f4f3`，同一账号资料目录重开后实际回显上述执行合同，检测为 `logged_in / confirmation_required`，无需扫码：[新窗口](../.tmp/native-profile-open.json)。已请求维护者确认新窗口账号，未代填确认；当前新任务0步/0候选，尚无新模式真实阅读或模型分析。临时创建脚本曾在201成功后误读未展开字段；通过唯一任务只读恢复同一编号，没有重复创建或改动产品。
+
+历史核对：旧任务14条成功步骤、2份候选完整读回、原初筛及4条既有失败/部分阅读保持不变，legacy配置未补写，新服务健康且数据库为PostgreSQL：[重启与历史核对](../.tmp/native-profile-history-check.json)。旧候选实际能力和失败仍按原证据报告，第二篇未运行；没有关注、私信、评论或回复写入。
+
+收尾核对：API及前端代理正常、首页200、PostgreSQL，新服务实例与重启记录一致；修改/新增源码97份及构建产物3份对实际配置Key精确扫描0命中，`.env`仍忽略：[本机检查](../.tmp/native-profile-final-qa.json)。图解8页无脚本错误或节点溢出，本地文档链接通过，已查看更新后的学习页截图：[图解与链接检查](../.tmp/native-profile-doc-check.json)。源码语法和局部差异检查通过；未重跑旧阶段全后台、检索扩展或macOS验收。
+
+未完成与下一步：按整体方案第14.2节，新窗口账号确认后以新配置全新录制搜索及案例正文/首层评论，冻结独立版本并静态检查，再执行一次来源绑定完整回放。遇新失败留证停止，不自动重试或改写旧记录；只对实际来源核对通过的可用正文/评论分析。账号延后反馈、真实分页移动、业务质量、独立读回、未来桌面共用内核接入、macOS与正式发布仍待完成。
+
+提交/推送：本轮未执行；账号资料、原文、截图及报告继续仅保留本机忽略目录。
+
+## 2026-10-25-08：新模式全新实录、首篇完整探索通过及文字需求分析
+
+目标：接维护者“账号正确，继续学习”，在已加载的新配置下重新学习并验证搜索到正文/首层评论，不复用旧模式成功步骤冒充新证据。
+
+真实实录：通过受限维护入口确认当前新窗口账号，`logged_in / ready`，没有重开或重复扫码。新任务 `learn_cbf78367730748b59da7cc0c2ec6f4f3` 新增9条成功步骤：搜索输入、回车、显式范围等待、结构化搜索提取、整页有界定位、固定标题点击、详情等待、正文、评论。搜索等待前后均已出现18个标题，不能称实际轮询从零等到结果；四步搜索提取5条完整卡片、跳过4条不完整、明确截断。定位实录实际从0滚到320像素并找到目标，不据随后标题数量变化认定分页因果。正文1条，评论3批新增0/0/1、去重后1条完整首层评论、跳过3条不完整，结束为批次数上限 `batch_budget`，不是时间预算失败。
+
+新候选分别冻结并静态通过：四步 `candidate_6c67fdac11624f53b8ebb07451a5fe45`，摘要 `4515eab84b3902ab4a9a63dfa86aa6898716efece48bda3802fb6c14afb7f20e`；八步 `candidate_6c5f1066ff6d42e68c0a7e889e6061e4`，摘要 `e435f1973e6c6f828744e01b92dc446496b5fe6b959741d57ba0d780a30641e0`，仅取本轮1/2/3/5/6/7/8/9步：[搜索清单](../.tmp/native-profile-search-candidate.json)、[八步清单](../.tmp/native-profile-detail-candidate.json)。离线逐项审计9步、18份前后观察及3份批次观察均实际回显同一profile和精确三字段合同，步骤、冻结引用及摘要一致。保存窗口中按序号/时间去重有60条 `native_page_traffic` 允许标记、阻止0；仅指保存窗口，不代表完整网络日志或账号延后状态：[实录审计](../.tmp/native-profile-recording-audit.json)。
+
+一次完整真实回放：对原初筛首篇执行 `reading_d529b7e1a6db46b7801922acab373964`，关联 `validation_ff910a5ee1d74e8db51e103cdfb07d58`，**exploration / passed**，阅读 **completed**。从入口重新搜索到笔记、正文和评论全部8步通过，固定笔记编号/标题/来源核对通过；实际回显新配置合同。取得正文1条和去重后2条完整首层评论，3批、`truncated:true / stop_reason:batch_budget`，仅表示冻结的有限范围完成。工作进程总耗时 **14.297秒，已包含入口4.488秒**；后台整次请求16.453秒。回放定位零次移动，实录320像素与回放零移动分别报告，不冒称分页完整验收：[实际验证](../.tmp/native-profile-reading-validation.json)、[业务阅读](../.tmp/native-profile-reading.json)。已查看实录及回放的实际末批PNG；验证12份观察的profile再次核对一致。
+
+来源与旧历史：本轮沿用已保存的 `discovery_40adbe10d64f4542b801562e4afb73bc` 提供可信关键词/目标来源，新详情回放重新从入口搜索；原初筛不是新profile验证，不能称整个新搜索初筛闭环已通过。旧初筛、4条失败/部分阅读、2份旧候选及14条旧成功步骤逐字读回不变，新八步manifest及摘要读回一致；当前初筛下只新增本条阅读，新会话仍登录/ready：[最终读回](../.tmp/native-profile-final-check.json)。四步新搜索候选目前只有实录和静态检查，未另建搜索初筛回放，没有自动运行第二篇。
+
+模型验证：仅向模型发送本次来源核对通过的正文/2条评论文字，3个来源、657字符。新增 `analysis_aae778abf4c5410aae59a9089c016ec4`，`renovation-demand-v3 / demand-result-v2`，**completed**；主槽 `deepseek-flash` 一次成功请求，2.250秒，供应商实际返回1822 Tokens，费用未知。正文被识别为提供装修服务、建议看评论；两条联系咨询短句被保守判为 `insufficient / role:unknown`，地区、预算、阶段不推断。模型结构/引用通过不作真实业务准确率：[分析记录](../.tmp/native-profile-analysis.json)。
+
+人工核对：维护者随后明确确认两条均“有咨询意向，可保留为线索，实际装修需求待核实”。据此通过受限入口各追加一条 `corrected`，注明维护者对话确认、Codex代录；仅将表达改为 `question`、业务相关性改为 `relevant`，保留 `role:unknown / demand:insufficient / match:insufficient`，不补造自身需求、身份、地区、预算或阶段。核对备注保留“待核实咨询线索”业务意见，现有五维没有独立线索状态，不能据备注宣称已建线索库。两条分别为 `review_3edb0c3a1ca54a468e30870174150e86`、`review_ade9c9f4b0f649d6844019eb6a8d4e98`：[评论1核对](../.tmp/native-profile-review-comment_1.json)、[评论2核对](../.tmp/native-profile-review-comment_2.json)。统计为3来源/已核2/待核1，正文未人工核；只计两项表达和相关性纠错，不报模型准确率。原分析完整读回不变，人工保存新增模型与平台调用均0：[核对统计](../.tmp/native-profile-reviews-summary.json)。

+涉及变更与边界：本轮没有修改产品代码、数据库结构、请求策略或模型提示词，只补忽略目录内的受限维护脚本和同步方案/进度/入口/图解状态。没有重跑07阶段工程套件、迁移、检索扩展或macOS。当前只取得一个新模式真实探索样本；正式模式基线、过程复查、官方消息等延后反馈、独立身份来源读回与发布均未完成。没有关注、私信、评论或回复写入，模型建议未执行。
+
+收尾核对：人工追加后再次读回，2条核对、原分析、当前阅读及4条旧阅读和旧初筛保持一致，只有1次模型调用、1822 Tokens，正文仍待人工核；当前会话仍 `logged_in / ready`：[核对后读回](../.tmp/native-profile-review-final-check.json)。API和前端代理正常、首页200、PostgreSQL实例不变；修改/新增源码97份及产物3份对实际配置Key精确扫描0命中，`.env`仍忽略：[本机检查](../.tmp/native-replay-final-qa.json)。图解8页无脚本错误或节点溢出、本地文档链接检查通过，已查看更新图解及真实回放末批PNG：[文档核对](../.tmp/native-replay-doc-check.json)。文档差异及临时维护脚本语法检查通过，本轮无产品构建或工程套件重跑。

+
+## 2026-10-25-09：有界笔记背景、独立咨询意向与新版分析实样
+
+目标：接用户“继续”，实现第14.2节已确定的咨询合同，让联系咨询可保留待核，同时不补评论者的自身装修需求、身份或地区；在原阅读上追加新版本，保留旧分析及人工意见。
+
+实际实现：
+
+- 新增 `apps/server/consultation.py`，服务端生成固定来源图：笔记无背景引用，评论只引用同一来源绑定阅读的笔记。原文只发一次，保持21来源/16,000字，不把每条评论拼成重复正文；作者、真实评论编号、链接、图片和凭据不进入模型负载。背景资料仍按不可信数据处理，不产生工具动作。
+- 新提示 `renovation-demand-v4`、结果 `demand-result-v3`。每条结果独立保存咨询 `yes/no/unclear`、本条逐字依据及关联笔记背景依据；引用分别核对，禁止其他评论/外部来源、缺失字段或模型自填动作。yes/no须本源依据，评论yes另须真实笔记引用及相关的询问/求建议/自身需求表达；无文字媒体由程序保留未知。程序派生 `lead_disposition` 与有限展示建议，咨询yes或相关自身需求可保留待核，不提升原 `match` 或补身份/地区/预算/阶段。
+- 新六轴人工核对采用 `analysis-review-v2`，本条和背景证据分别保存；旧 `demand-result-v2` 继续原五轴 `analysis-review-v1`，禁止混入新字段，更早结果保持只读。版本、阅读、模型配置及商家条件参与复用，不将旧分析或人工标签升级到新版本；无数据库schema变更或独立线索库。
+- 后台分开展示咨询意向、保留待核、自身需求与匹配，标明本条/笔记背景依据及来源。旧结果明确历史未记录；新旧核对表单分别提交，打开或预填不保存，纯媒体不确定、版本冲突和地区不足的保护保留。
+- 首次真实输出失败后，新增固定无文本合同诊断：仅 `MODEL_OUTPUT_INVALID` 且16种允许检查枚举才可保存 `output_diagnostics:{check}`。旧五轴与新咨询检查的允许范围、原错误码不改；不存原始模型输出、来源编号、URL或供应商错误，成功不带诊断、旧失败不回填，不自动重试或升级模型。
+
+涉及文件：服务端 `analysis.py / analysis_reviews.py / consultation.py`；后台类型、`ReadingDemandAnalysis / AnalysisReviewPanel / ConsultationDetails`；新增 `test_consultation.py / test_analysis_diagnostics.py`，旧 `test_analysis.py` 的服务模型夹具按版本调整。三份已有需求分析/人工核对/业务工作台验收脚本同步新负载及模拟结果，旧纯合同和伪历史不补新字段；共享已有改动保留。同步README、维护入口、整体方案及原图解。
+
+最终后台验证：诊断补丁冻结后，7份目标/相关回归单轮 **116 passed、无跳过，83.21秒**：[最终后台报告](../.tmp/test-consultation-diagnostics-current-final.log)。覆盖咨询、分析、五/六轴核对、固定诊断及商家条件衔接，使用隔离SQLite、真实专用PostgreSQL随机schema、MockTransport/FakeWorker；真实平台、模型及开发库调用0。前阶段41/72/3项及单目标不累加为当前计数。
+
+前轮115通过/1失败保留：[前轮报告](../.tmp/test-consultation-diagnostics-final.log)。唯一失败为既有现实计时夹具在80ms总截止内假设必进入两个密钥槽，本机先到总截止、只记录一个尝试；未改变产品超时。仅将夹具改为500ms总预算/300ms单次，仍短于两个完整单次窗口，并要求主备顺序、两次超时、实际墙钟与尝试耗时合计均小于900ms；先该目标通过，再完成上述116项最终单轮。没有因此放宽来源、分类、网络或生产截止。
+
+界面与应用贯通：TypeScript检查、生产构建通过，最终构建约1.30秒，仅既有chunk提示。隔离Edge界面单轮 **13项通过**：[界面报告](../.tmp/consultation-ui-1792912666653/summary.json)，48次内存请求/6次模拟核对，真实API/平台/模型调用0、页面错误及意外请求0，390px无横向溢出，已查看桌面和窄屏截图。媒体下拉夹具的嵌套抽屉动画/聚焦时序失败保留，最终仅修测试等待实际内容和目标选项，不改产品边界。
+
+现有 `test-analysis-review.mjs` 一次真实本机Edge + 临时API/Vite + 专用PostgreSQL随机schema + loopback模拟模型集成通过：[应用集成](../.tmp/analysis-review-acceptance-1792912632849/summary.json)。新v3分析、六轴核对、7条追加记录、双击单POST、422修正反馈、409显式重开、媒体未判定、旧只读历史、980px及重启读回通过，核对阶段模型/夹具网页请求及写入0、页面错误0。该完整集成在最后诊断补丁前完成；诊断只追加失败元数据，随后由最终后台目标覆盖，不冒称补丁后整条重跑。另两份验收脚本仅维护及语法检查，未运行全量。
+
+已标注样本离线合同：用原阅读3个来源/657字符及维护者对两条短评论的判断，构造严格分源证据验证咨询yes可保留、需求/角色/匹配和地区不继承：[离线报告](../.tmp/consultation-labelled-offline.json)。模型、平台、数据库调用0，不是对模型语义质量的评测。
+
+真实模型与加载：经受限入口关闭旧学习窗口，停止本任务持有服务并确认端口释放，受控重启加载新代码；本轮只分析已保存文字，没有重开小红书或要求账号确认。首轮新增 `analysis_924580d95542475499b750f69c41e005` 为 **failed / MODEL_OUTPUT_INVALID**，主槽一次约2.657秒、2547 Tokens，未返回可用结果。原设计不保存raw，该失败没有具体合同拒因；后加诊断不回填：[首轮失败](../.tmp/consultation-live-analysis.json)。
+
+加载固定诊断后，明确执行一次后续独立验证，新增 `analysis_238192eb0b8144c9a7af7fcc6aae92fd` 为 **completed**，主槽 `deepseek-flash` 一次约3.563秒、2620 Tokens：[后续分析](../.tmp/consultation-live-analysis-diagnostic.json)。正文服务推广为咨询no/不保留本人线索、建议看评论；两条短评论均咨询yes/保留待核，本条原话与笔记服务背景分别引用，自身需求insufficient、角色unknown、地区/阶段/预算null、业务匹配insufficient。后续成功未重现首次失败，不能据此确认首次具体原因或声称修复了它；两次新调用合计5167 Tokens、金额未知，未走备用或改变模型，未自动重试。
+
+历史与范围：原阅读、原v3提示/v2结果分析、2条旧五轴人工纠错及9条学习步骤逐字读回不变；本轮新增两条模型记录（1失败/1完成），新分析人工核对0，不自动迁入旧人工意见。当前服务健康、PostgreSQL，浏览器为closed：[读回核对](../.tmp/consultation-live-history-check.json)。没有新的平台读取、第二篇、关注、私信、评论或回复操作，没有商家桌面或正式发布。两个同向短句来自同一笔记，不能作整体准确率、召回率或稳定性结论。
+
+收尾核对：API及前端代理正常、首页200、PostgreSQL，新服务已加载且与实际新分析实例一致；修改/新增源码101份及产物3份对实际配置Key精确扫描0命中，`.env`仍忽略：[本机检查](../.tmp/consultation-final-qa.json)。图解8页无脚本错误或节点溢出、文档本地链接通过，已查看更新图解及隔离咨询详情截图：[文档核对](../.tmp/consultation-doc-check.json)。语法及文档差异检查通过；未重跑旧Playwright完整worker、迁移、检索扩展或macOS验收。
+
+未完成与下一步：按整体方案第14.2节，补固定评测集的正反例和更多真实标注，分别核对咨询意向与自身需求，保留无效输出；随后验证新搜索候选的独立初筛及新来源衔接、正式运行基线与任务后反馈。平台独立身份读回、Windows/macOS桌面和交付仍未完成。
+
+提交/推送：本轮未执行；真实文字、账号资料、截图和报告继续仅留本机忽略目录。
+
+
+## 2026-10-25-10：收回平台链路主线与独立复用验证
+
+目标：按维护者确认，暂停扩展装修需求/咨询分类与标注，完成“学习操作→固化版本→轻量召回→换参执行→结果核对”；现有业务代码与历史保留，桌面端继续后置。
+
+实际实现：
+
+- 新增 routes 服务及后台“学习→链路复用”入口。目录从已有冻结候选识别 search_notes/read_note_comments，结构化平台/任务类型召回；显式固定候选ID与摘要，歧义不静默选最新。目录不全量哈希历史截图，明确只展示最近静态记录；召回与执行完整重验来源和摘要。
+- 首版要求同任务、同站、同profile/执行合同，并复用同一学习会话。搜索按本次实际结果的合法来源、唯一标题/编号衔接一篇详情，不套装修规则，不调用商家条件或业务模型。现有详情能力仍含入口搜索前缀，组合会搜索两次；尚未学到独立“当前结果页→详情”能力，不能称原子拆分或最省动作。
+- 两阶段沿用原exploration浏览器验证；组合追加kind=route汇总，独立保存route_status、固定版本、参数、阶段验证引用及证据，不新增表/迁移。actual_outputs保留阶段取证；usable_outputs仅保留结构/来源/绑定通过的结果。失败不自动重试，正文可部分保留，零评论不伪装已学空态。route不参与候选维护状态或发布资格；旧脚本测试列表排除组合记录，通用详情定向专属链路页，避免填写浏览器质量。
+- 增加共享任务占用及内部上下文：组合期间外部浏览器变更、单候选验证及第二组合返回ROUTE_BUSY；入口和RPC边界两次检查，内部两阶段允许，finally释放。GET状态可读，不新增自动登录或发布。
+- 维护者明确要求保留登录态时不再逐次询问账号。后续本地Codex沿用已授权固定学习账号，先检查已登录再完成ready；登录失效、需验证或异常才提示。该会话操作沿用现有API，未实现新的自动身份核验或登录凭据处理。
+
+涉及文件：apps/server/routes.py、main.py、learning.py；后台RoutesPage、主壳/侧栏/类型和验证展示；control入口与测试；新增test_routes.py、test-routes.mjs、test-routes-ui.mjs及package命令。README、整体方案第10/14节、会话说明和现有图解同步；共享已有改动保留。
+
+最终工程验证：
+
+- 路由目标单轮 **23 passed**，405.26秒，SQLite与真实专用PG随机schema，FakeWorker，无真实平台/模型/开发库调用：[最终路由报告](../.tmp/test-routes-final.log)。覆盖非装修参数、版本歧义、摘要/来源篡改、绑定失败、部分结果、归属/CSRF、不可变历史和异上下文占用。此前18项和单目标不累加。
+- 最终既有learning/discovery/reading的SQLite回归 **26 passed、4 deselected**，44.60秒；4项专用PG参数未在此单轮执行，PG由上述路由目标另验：[既有链路回归](../.tmp/test-routes-legacy-final.log)。
+- 最终真实本机Edge合成站组合贯通（专用PG隔离schema）通过：露营清单、咖啡设备两组新词完整输出；摄影器材保留部分正文；无会话零新增网页请求；重启读回历史及候选不变。模型/真实平台/网页写入均0：[浏览器贯通报告](../.tmp/route-acceptance-1792917198998/summary.json)。
+- 隔离Edge界面单轮 **10项通过**，16次内存模拟请求，真实API/平台/模型0，页面错误/意外请求0，390px无横向越界，已查看截图：[界面报告](../.tmp/routes-ui-1792917227566/summary.json)。初轮确有本页grid自动列撑大，已修；动画/定位夹具失败保留。此单轮后仅补旧验证详情的组合分流与列表过滤，由最终TypeScript检查/生产构建覆盖，不冒称界面全量又重跑。
+- 控制入口目标通过；最终TypeScript检查、生产构建通过，构建1.41秒，仅既有chunk提示：[前端报告](../.tmp/test-routes-admin-final.log)。未重跑商业模型、迁移、检索扩展或macOS。
+
+真实平台验证：维护者确认当前账号后，使用同一新模式冻结搜索与八步详情候选执行新词“装修顺序”。组合 validation_024ccd66f016430d899f297d804eb111 **failed**；搜索阶段通过，取得3条有界结果；详情第4步滚动根未在当前采集中定位，UNOBSERVED_SELECTOR及未完成的NOTE_BINDING_MISMATCH保留，blocked_request_count=0。失败没有正文可用输出，未原样重试：[首轮组合](../.tmp/route-live-run.json)、[阶段诊断](../.tmp/route-live-stages.json)。
+
+修订与复验：从同任务已成功实录步骤选取新七步版本，去掉当前不必要的滚动，只声明当前可见搜索结果范围，未修改旧步骤/候选/失败。首个七步组合 validation_d6239a52a1d54b228657fd92e4112fa6 为 partial：正文及来源绑定通过，评论三批已到预算但还未越过长正文；没有当作平台无评论。核对真实截图后，用同一已观察根补录每次640px、最多5批、最多6条的有界读取，实际取得6条；仅追加1条真实步骤，再冻结新七步候选，重新完整复验。新七步候选 candidate_9d79ad9f21084c5097c039fd2002d3f3 静态通过后，使用同一新词重新验证，组合 validation_35d567240bca4416930f0098c7d79be5 为 completed；本次搜索取得3条，正文1条，首层评论6条，首层评论共5批、去重1条、范围截断，不代表全部评论。 详情版本与来源均独立核验，不继承旧成功；模型调用0、未发布：[最终修订组合](../.tmp/route-live-range-run.json)、[长正文前部分结果](../.tmp/route-live-revision-run.json)。仅为一个关键词/一个对象的真实探索证据，不代表更多页面、正式运行或双端交付。
+
+未完成与下一步：按整体方案第14.0–14.1节补声明范围的新参数/对象、独立结果页入口和缺失分支，再补正式基线及任务后反馈；客户意图、分类质量、桌面及跟进写操作均不前置。没有关注、私信、发布评论或回复。
+
+提交/推送：本轮未执行，真实文字、截图、浏览器资料和本机报告仍位于忽略目录。
+
+收尾读回：原2个候选清单、原9条步骤、原阅读/模型和2条旧人工意见逐字未变；实际仅追加1条评论范围学习步骤，失败/部分/完成3条组合记录均完整读回。当前API与前端代理使用PostgreSQL且正常，平台会话仍已登录/ready：[最终读回](../.tmp/route-live-final-readback.json)。图解8页无脚本错误或节点溢出，本地文档链接已核对：[文档检查](../.tmp/route-doc-check.json)。没有提交/推送。
+
+## 2026-10-25-11：功能入口分层盘点、公开主页导航及实际安全验证暂停
+
+目标：根据维护者要求，把作者/评论者主页、关注/私信及下级入口纳入学习，逐层盘点当前账号网页版功能；动态内容取样，业务分类继续后置。
+
+已实现：后台新增“学习 → 平台路径”，五组33个初始功能模板及父子层级，支持筛选、搜索和实际任务证据直达。不新增数据库/API或业务模型；只读取盘点任务，以分类标记、官方页面、实际可见非敏感元素与已登记截图引用共同核对。当前18项已观察、15项待探索；作者入口仅匹配实际固定布局及唯一可见锚点，不使用昵称推断。它是入口观察目录，不把观察、真实动作、固化、验证和发布混为完成；旧组合探索记录单独核对固定候选/实际阶段引用。
+
+新增显式 `playwright-xhs-navigation-ui-v1` 及精确三字段合同，支持已观察且固定实际对象的发现/搜索/笔记/公开主页/通知链接；旧v1、legacy、候选及失败不改。普通读取继续限定根/字段/预算。真实笔记跳转标准别名按同编号核对；主页仅兼容实际取证的 `channel_type`、`parent_page_channel_type` 省略，各最多一个，必须实际省略至少一项，其余有序query、xsec值、路径/对象/hash不变。新窗口必须是本步明确目标及opener的实际主框架，仅沿用原动作策略及截止时间，不续签。没有放行任意按钮、div或消息发送。
+
+真实取证：盘点任务 `learn_cc0a31cb28284c7daca116c82efe4304` 保存25条成功步骤、86份观察，无候选；进入搜索、笔记、首层评论、通知、自己的主页，并保留发布者/评论者主页实际打开的观察。复验任务 `learn_43196c6fb80e449ba4e3679d52b8989d` 保存23条成功步骤、58份观察，无候选。最终加载修订后，发布者主页点击 `step_dc951617dd0743cda553d7eccee21e05` 通过，来源与实际执行合同一致；评论者主页尚未完成最终复验，不能继承发布者或旧只读链路成功。全程模型调用0，未关注/取关、发送私信、发布评论或回复。
+
+失败与修订依据：宽泛导航链接读取因包含不允许输出而停止；笔记别名曾触发本地来源误判并阻止21条通信；首次评论者弹窗打开后，3条主框架通信因归属校验误判被阻止。修订后的弹窗阻止为0，但完整地址末校验仍失败；新增只含11个固定无文本字段的诊断，绑定实际新profile及 `NAVIGATION_BINDING_MISMATCH`，对成功/旧记录不补。受限普通根进一步读取唯一主页链接，确认站点去掉两个入口上下文参数、对象和两项xsec未变，随后最小修订并实测发布者通过。第一次链接字段不唯一的失败保留，改为精确相对容器后取得1条链接。所有失败原样留档，不反写成功。
+
+实际暂停：最终发布者主页通过后，返回首页的截图出现官方“安全验证”，可见页面检测为 `verification_required`，后台 ready已撤销，后续搜索未执行；截图已查看。已停止平台操作并请维护者在官方窗口手动验证，保留当前窗口。不能把此次安全验证归因于某一工具或某一动作，也不能报告全程无提醒、正式运行通过或账号权重无影响。原弹窗/地址误判与这次真实平台验证分别记录。
+
+工程验证（分别报告，不累加）：
+
+- 新导航最终单轮 **19组/888断言通过**：[报告](../.tmp/navigation-profile-6J5z4m/report.json)。含纯边界、实际本机Edge DOM及popup；popup的真实Page/Frame/opener配合明确合成的官网URL投影验证合同，不是真实官网或完整worker端到端。
+- 旧v1最终单轮 **16组/809断言通过**：[报告](../.tmp/native-ui-profile-ZLasDu/report.json)。legacy策略650断言在较早弹窗补丁后通过，后续仅新导航比较/诊断修改，未将其当作最终再次重跑。
+- 后台初轮导航/旧profile/动作失败目标 **30 passed**：[报告](../.tmp/test-navigation-server-final.log)，在最后诊断补丁前完成；最终诊断目标单轮 **12 passed、无跳过**：[报告](../.tmp/test-navigation-comparison-final.log)，覆盖SQLite、专用PostgreSQL随机schema及FakeWorker实际API失败/验证保存，旧模式隔离、成功不补和历史不变。两轮不是最终全后台。
+- 最终隔离Edge界面 **10项通过**，TypeScript及生产构建通过：[报告](../.tmp/platform-paths-ui-1792920829357/summary.json)。没有真实API/平台/模型调用；作者入口反例及390px无溢出通过。最初夹具误拦任务页合法延迟截图的失败报告保留，修正夹具后重跑。
+- 本机实际后台的目录读取和桌面/390px几何检查单独执行，页面刷新不操作平台：[界面读回](../.tmp/xhs-paths-live-ui.json)。旧任务10条步骤及4份候选完整读回未变，API/前端代理和PostgreSQL正常：[最终核对](../.tmp/xhs-paths-final-audit.json)。真实会话仍等待官方验证。
+
+涉及文件：后台平台路径页面/证据规则与入口接线、执行配置表单/显示及类型、服务端执行合同与诊断清洗、Playwright配置/策略/工作进程、对应Python与Node/UI目标测试，以及README、工具说明、整体方案和现有图解。图解8页无脚本错误或节点越界，210个本地文档引用存在，已查看学习页截图：[文档检查](../.tmp/path-doc-check.json)。
+
+未完成与下一步：以整体方案第14.0.1节为唯一当前顺序；先由维护者完成官方验证，再检测当前状态并复验评论者主页。随后补非语义菜单/标签/回复开关的固定识别与真实状态断言、安全关闭/返回、通知分类和消息窗口，再按模块参数化、冻结和独立变参验证。未捕获或被元素上限遗漏不等于不存在；本轮没有完成全站、写能力、正式发布或双端交付。

-固定执行层负责打开页面、点击、输入、滚动、等待和读取，首选 Playwright，按本项目的能力契约封装与验证。一个运行会话明确由一个驱动持有。每个平台账号绑定独立的浏览器数据目录，保留其登录状态。产品账号、平台账号和浏览器目录分别建模。
+固定执行层负责打开页面、点击、输入、滚动、等待和读取，已确定采用 Playwright，学习端与桌面端按同一执行合同封装与验证。一个运行会话明确由一个驱动持有。每个平台账号绑定独立的浏览器数据目录，保留其登录状态。产品账号、平台账号和浏览器目录分别建模。
 
 **登录交互。** 商家在软件管理的浏览器中打开平台官方页面，自行扫码或输入手机号、验证码等登录信息。我们的产品账号界面不索取这些平台登录信息，也不代收验证码。登录阶段业务执行器暂停动作，商家持有操作权；登录判定只读取必要的已登录页面标志及账号标识。手机号、验证码和密码不进入业务数据库、日志、学习证据或模型输入。
 
 **登录成功的判据。** 等待平台完成登录跳转，并检查可用的已登录页面标志和可靠账号标识，绑定到本地账号记录。二维码消失、登录弹窗关闭、已有 Cookie 或数据库上次记为已登录，都不能单独证明当前账号有效。身份不明、与任务预期账号不一致或仍需验证时，保持等待处理。具体判据按平台学习、验证和维护。
 
+学习端当前已实现“先检测，再确认”：打开或刷新时根据可见导航、登录窗口和验证控件返回 `logged_in/logged_out/verification_required/unknown`，不读 Cookie、存储或表单值。已登录时提示无需重复扫码；身份仍以维护者授权为准。本地Codex协作时，维护者已明确授权持续使用固定学习账号后，后续同账号资料目录、同执行配置且可见页面检测已登录时，可沿用该授权完成维护会话ready，不再逐次询问；这不是新增平台身份自动核验功能。资料或绑定变更、登录失效、平台要求验证或会话异常时暂停处理，不把该授权用于任意账号。明确未登录/需验证会阻止执行并撤销旧确认，恢复后重新确认；未知只表示依据不足，不自动判定退出，也不撤销已有有效确认。当前检测适配仅覆盖小红书，其他平台可返回未知。
+
 **登录后的窗口。** 首选在同一浏览器会话中从人工操作移交给执行器，登录完成后回到控制台；可最小化浏览器继续执行，提供重新显示和接管入口。最小化对视频加载、读取和任务推进的影响在 Windows/macOS 分别验证；未验证前保留可见执行方式。关闭整个浏览器会结束当前执行会话，运行端应暂停任务并保存检查点，不能把关闭窗口视为浏览器仍在执行。首版不将可见登录后自动切换无头运行作为默认流程。
 
 **下次如何复用。** 每个账号分配固定的专用资料目录，使用 Playwright 的持久化上下文打开同一目录，保存浏览器支持持久化的 Cookie 和本地存储等资料。目录位于应用本地数据区，与安装目录分开；正常重启、任务结束和客户端升级保留目录。SQLite 保存账号标识、目录引用、会话状态和最后核验时间，平台登录资料由浏览器管理。
 
 如采用内嵌浏览器，由 Electron 的稳定 `persist:` 会话分区保存资料，执行器连接该宿主的实际页面目标；上层仍按本地平台账号映射会话引用。独立浏览器目录和 Electron 分区是两种存储实现，不把登录页放在一个会话、执行页另建到空白会话，也不依赖复制两种实现的 Cookie 来切换。现有测试工程在新建会话时追加随机标识，需改为稳定的账号作用域，并保留身份核验、控制权与账号互斥规则。
 
-新任务先复用已有浏览器会话；需要重开时先正常关闭并释放原会话，再用同一目录启动，打开页面核验账号和登录有效性。资料保留且平台会话有效时可直接执行，不需要每次重新扫码。平台会话到期、退出登录、资料清理或平台要求重新验证时，进入等待登录；不承诺永久免登录，也不设未经实测的有效天数。不同设备及 Windows/macOS 各自建立和验证会话，不将资料目录直接复制作为登录迁移方案。

+
+#### 三类业务任务
+
+1. **检索信息。** 用户给出问题或关键词、平台和范围，系统搜索图文/视频，按需要读取详情、主页及评论，返回带来源的信息与摘要。一次查询不一定形成客户线索。
+2. **发现潜在客户。** 商品与客户条件 → 搜索或有限浏览 → 内容相关性判断 → 主页/角色与评论上下文 → 需求匹配 → 线索去重与依据保存。同行内容下的评论者和作者本人表达的需求分别处理。
+3. **跟进互动。** 对已经明确的对象选择关注、私信、评论或回复指定评论/回复。动作绑定平台、账号、内容及评论层级，记录内容、结果与去重依据。正文生成、对象核对和动作执行分别处理，不能因一条评论相关就自动认定有采购意图。写操作仍须单独学习、限定验证和确认实际支持范围，当前只读执行器尚未支持。
+
+#### 一个后台、一套浏览器执行与必要的 AI
+
+当前保留已有学习后台、FastAPI/PostgreSQL 账本和浏览器工作进程。业务层只需任务配置/状态、平台链路清单、内容分析和线索/互动记录。任务控制正常步骤和分支；模型解析用户条件、判断内容与需求、按配置生成候选回复。无需为每次点击启动通用 Agent，也不按每个业务角色拆服务。
+
+从 A2A 保留目标限定、观察证据、参数化、候选版本、验证记录、失败修订六项机制。当前功能入口与页面层级盘点按第14.0.1节推进；全站动态内容穷举、多工作者租约、完整三级语义生产、公共 AC 协议、独立供给平台、通用 Harness 和复杂任务规划后置。参考项目仍只读；本项目不以完全兼容其协议或全部字段为验收目标。
+
+每条已学链路先保存：稳定标识与版本、平台/用途、真实支持的输入、结构化输出与来源、前置条件、步骤/结束条件、异常停止条件，以及证据和验证记录。样本参数与能力定义分开。笔记/评论输出记录必要的对象引用、父子关联和分页/截断状态；取不到的字段记缺口。可以先用类型定义加 JSON 清单，不以新建多层合同包、独立语义修订或索引代际系统为前置。Formily 仍为后续参数表单展示选项。
+
+#### 先把“检索”分成三个实际用途
+
+- **选用已学链路。** 能力少时，按平台和固定任务类型路由，缺条件再补问；自然语言可由模型解析成受限任务参数，程序核对已支持操作。无需每次先做 BM25/向量/Jev 选能力。
+- **到平台检索内容。** 将用户条件映射为页面搜索、筛选和有限浏览，读取真实内容，模型进行相关性、需求和摘要分析。这是获客首期的主要检索路径，数据库向量检索不能替代网页取数。
+- **查询已经保存的资料。** 对已有内容和线索先提供来源、关键词、对象及任务条件查询。数据和问法增多、简单方式效果不足时，再对明确对象接入 BM25/embedding，单独验证召回质量。
+
+已准备的 `pg_search` 和 `pgvector` 保留；本轮不删除基础，也不要求立即接满 C V8。以后引入混合召回时，再落实同模型配置、范围过滤、版本对应、索引更新与评测，不把每个点击或原始学习日志都当作能力文档。
+
+#### 页面操作与平台提醒的边界
+
+本项目固定执行已确定为 Node.js Playwright，学习与未来 Electron 桌面复用同一 profile、动作合同及结果核对。`tools/learning/browser-worker.mjs` 使用 `launchPersistentContext`；没有接入 Python browser-use，也不另建 `Agent.run` 自主执行路径。A2A 或 `D:\qiekj\browser_use` 的框架与进程设计可作参考，不能将参考工程的能力或账号表现当作本项目已实现。
+
+这里的操作要求是走正常可见页面路径、核对当前对象、等到页面状态就绪再进行下一动作；同一账号串行、限定本次读取范围和停止条件，尽量复用已取得内容，避免无意义刷新、重复搜索和失败连点。这些是减少错误与不必要交互的工程措施，不是平台不会识别或不会限制账号的承诺。DOM、视觉或 browser-use 均不能单凭技术名称推导账号安全；平台检测阈值和实际限制效果没有经过本项目验证。
+
+学习与实际用户账号、浏览器资料及统计分别管理。学习先用隔离的维护者测试资料，人工示范和有限自动执行交替取证；后续执行复用固定链路，不重复整站探索。探索记录允许出现非真人提醒等中断，已经取得的有效知识仍可保留，不要求探索全程无提醒。受阻步骤保存依据，等待人工处理及重新检查正常状态；异常期间的部分结果不能充当用户正常运行模式的验收证据。
+
+#### 固定执行合同：动作与页面原生通信分别约束
+
+当前小红书新模式为 `execution_profile:"playwright-xhs-native-ui-v1"`，合同固定为 `execution_contract:{engine:"playwright",action_policy:"xhs-bounded-readonly-v1",network_policy:"xhs-page-native-v1"}`，三字段和值须完全一致，不接受自由框架名、自定义网络规则或无声降级。新建小红书任务默认该模式；明确选择旧实验模式时省略 profile，其他平台不使用本 profile。
+
+功能路径盘点另选 `playwright-xhs-navigation-ui-v1`，精确合同为 `engine:playwright / action_policy:xhs-observed-navigation-readonly-v1 / network_policy:xhs-page-navigation-v1`，声明同站公开主页、通知及原搜索/笔记导航。它不修改旧模式或候选；非语义标签、菜单和消息窗口须补各自的控件检查与结果断言，不从任意CSS节点推导可点击权限。当前实际加载和取证状态见最新进度与第14.0.1节。
+
+工具动作仅开放官网声明页面内已观察且当前唯一、可见可用的搜索输入/`Enter`，固定实际对象的同站标准笔记锚点，以及普通非交互、不可编辑、非敏感区域的有界读取、等待与滚动。搜索结果核对本次关键词，点击前后核对固定笔记编号，读取前后和每批核对完整页面来源、实际根、字段与截图。关注、私信、评论输入和发布不在此合同内，未来写能力仍须单独学习及验收。
+
+页面原生通信不按接口名字推断业务写入。最长15秒的当前动作窗口内，当前主框架自然发起、无凭据URL且标准端口的第一方 HTTPS（`xiaohongshu.com` 及其子域）`xhr/fetch POST` 正常通信，包括安全通信；不再逐接口扩白名单。非第一方、子框架、非HTTPS、其他需策略授权的方法或资源类型、来源失配及到期继续拒绝；窗口不续签，动作结束即撤销。搜索仅接受转入本次关键词结果页，点击仅接受进入固定笔记，其他读取动作不接受完整地址漂移。GET/HEAD/OPTIONS 等既有被动通信语义保留，不能据此声称隔离了全部网络。
+
+这是一套受限工具动作合同，不是网络沙箱，也不保证页面或第一方通信在服务端绝无副作用。只通过可见页面动作与实际结果验证，不直接调用平台接口、执行任意 JavaScript、读取请求头/正文或增加指纹/伪装措施；不承诺防检测或账号绝不受限。本地拒绝、平台可见提醒、动作结果及任务后反馈分别留证。
+
+schema 10 为任务增加可空 `execution_profile`，旧任务保持空值、API 省略，不追溯补新模式。任务顶层只声明选定模式；`browser_readiness` 的 profile/contract 来自当前已核验会话，未打开不填。候选 `manifest` 保存冻结配置；浏览器验证 `environment` 保存执行器实际回显，初筛与阅读复制各自验证值，缺失显示未记录。静态检查配置不冒充实际执行，错配停止且撤销未证实会话。学习与未来桌面复用该协议，Windows/macOS 环境仍分别验收。
+
+legacy 保留未声明新 profile 的四类旧实验策略及原边界：搜索、打开笔记、普通只读辅助和搜索整页定位。它们的精确请求白名单与旧失败原样保留，只用于原合同复现/对照，不能把新模式通信范围写回旧候选或把旧成功继承给新模式。当前加载及真实新模式状态见第14.2节和进度。
+
+#### 学到了与可以交给用户运行分别验收
+
+本项目的交付目标是：用户执行已发布链路时，在声明的使用范围内稳定完成任务，不出现非真人提醒或功能受限。发现按钮、读取数据或一次跑通只证明部分操作知识；即使探索账号可接受出现提醒，也不能将该探索过程直接交给用户执行。
+
+每个版本保留两类记录即可：**学习探索记录**说明如何取得定位、步骤和异常知识；**正式运行模式验证记录**使用冻结的实现、实际拟交付的浏览器执行方式、正常起始会话、明确任务范围和参数，独立运行完整链路。后一类检查操作过程、任务结果、对象正确性、完整度以及当场与任务后是否出现平台提醒/功能限制，并记录浏览器、会话前置、样本与观察范围。平台也可能通过官方消息事后告知，不能以当场没有弹窗替代后续检查。更换关键词、目标对象及完整任务样本，而非只验证单次点击。
+
+能力清单只开放已通过相应运行范围验收的版本；实验候选留在学习端。验证中出现提醒或状态不明时，不能凭部分结果晋级。已开放版本在实际运行中出现提醒，停止该任务并将该版本置为待复核，防止继续分配新的相同任务；保留依据、排查原因并重新验证后再恢复。学习有所得、验证通过与当前可用三种结论不混为一个“已学会”。这是一套轻量发布质量规则，无需复制 A2A 的完整供给系统。
+
+有限样本未出现提醒，只能证明该版本在已测范围和时段的表现；不能保证任意账号、负载、平台更新后永不提醒，也不能仅从是否显示提醒量化账号权重变化。当前已有有界链路的正式执行及过程复查，任务后官方通知和功能复查尚未完成，不能宣称已经达到上述交付目标。
+
+运行阶段需要异常暂停、人工接管和恢复核对；发送或回复结果不明时先核查，保留未知状态。当前只有人工会话确认与基础错误处理，尚未实现平台专属提醒识别、版本停用/恢复或真实账号权限验证。框架和表面上的动作形态不能代替正式运行模式验证。
+
+框架事实参考：[browser-use 官方浏览器配置](https://docs.browser-use.com/open-source/customize/browser/all-parameters)和[真实浏览器连接说明](https://docs.browser-use.com/open-source/customize/browser/real-browser)。这些说明浏览器控制、配置与会话能力，不能据此推导小红书/抖音的检测结果或账号长期稳定性；后者须依据限定平台测试记录说明。
+
+#### 当前阶段怎样验收
+
+先验收小红书“搜索笔记 → 详情 → 评论读取”的正常路径、无结果、登录/平台提醒中断，以及输出和对象来源一致性；随后检验商品条件下的相关内容与需求判断，统计人工确认的误判、漏判、信息不足、耗时和费用。再分别学习和测试关注、私信、发布评论与回复指定评论；不能用只读链路通过替代写操作验证。
+
+用户输入能否选择已有链路、参数能否正确传入、输出能否回答问题、线索是否有原文依据和动作是否重复，是首期闭环指标。框架、学习资料、内容判断、真实平台操作和账号状态分别报告。修订候选已有两组正式执行及过程复查，账号任务后反馈、模型判断和跟进功能仍未完成。
+
+#### 参考核对保留的事实
+
+参考 A 仍为 `main / db7b54a`，与此前核对相同；C V7/V8 是本机未提交设计资料，正式服务尚未初始化。A 的输出投影限制、持续资格桥和语义接入缺口仍存在，但不再要求本项目先补齐整套 A/C 体系。上轮核对过程保留于开发进度第 2026-10-24-02 条，当前实施按本节和第 14 节执行。
+
+### 5.11 学习端实施方案与首条任务
+
+本节落实第 5.10 节的轻量方案。通用工具与维护质量记录已实现，分批修订候选已完成静态校验、两组真实正式执行及过程复查，具体证据见开发进度。当前等待维护者复查账号后续反馈，并继续补平台真实空态、异常和回复层级样本。
+
+#### 谁做什么、使用什么
+
+- **维护者：** 在学习后台打开的专用浏览器中自行登录，确认用于学习的账号；必要时演示一遍日常使用路径，供操作质量对照。无需编写脚本，也不在后台提交手机号、密码或验证码。
+- **本地 Codex：** 经学习后台/受限工具控制同一个浏览器会话，观察页面、整理状态和字段、编写参数化固定实现、提交候选，并依据校验和试跑结果修订。Codex 侧边浏览器与日常 Chrome 的登录态不作为该会话依据。
+- **学习后台：** 保存任务、资料引用、步骤/输出、候选版本、两类验证及后续观察；维护候选是否处于实验、待观察、验收通过或待复核状态。界面在现有批次、候选和验证记录中补齐，不另建复杂调度系统。
+
+继续使用 React/TypeScript 后台、FastAPI、PostgreSQL 和 Node.js Playwright 工作进程。浏览器采用可见的持久会话，同一会话一个驱动持有控制权。固定执行与桌面复用 Playwright 协议，不为“像人”另建 browser-use `Agent.run` 路径；视觉辅助仍须有明确用途并单独验证。先保留一个应用和现有数据库边界，暂不建设完整 A2A 或商家桌面。
+
+#### 第一条学什么
+
+目标固定为小红书网页端“关键词搜索笔记 → 打开指定结果详情 → 读取有限评论/回复 → 返回结构化结果与来源”。一次任务明确关键词、内容选择条件、本轮内容/评论范围、结束条件及读取不足时的返回状态；不承诺读完所有历史评论，不包含关注、私信或发布回复。
+
+输入先只开放实际支持的参数；输出至少关联当前笔记/作者引用、正文来源、评论与父评论关系、本轮读取结果和完整/截断/未知状态。无法可靠获得的标识或字段保留缺口，不能猜测补值。正常结果、无搜索结果、空评论、加载结束、读取范围耗尽、登录失效、页面不支持及平台异常分别表达。
+
+后续学习按需求增加主页/推荐流及互动能力；关注、私信、发评论、回复指定评论单独建立学习目标和测试用例，不能从只读流程直接开放。关键词、商品和选择对象作为参数变化，不为每个客户重新学习整条流程。
+
+#### 一条链路怎样学成
+
+1. **建任务并确认会话。** 新模式显式固定 profile 和读取范围，维护者登录并确认账号，核对实际会话合同，记录正常起始页面与可观察的功能状态；旧任务不原地切换模式。
+2. **取得正常路径基线。** 观察日常页面操作，记录搜索、打开、滚动、评论展开等必要步骤；每步明确前置状态、当前对象、动作、完成反馈和退出条件。操作需与当前可见页面和实际反馈对应。
+3. **有限探索与补证。** Codex 在相同会话中按目标补齐定位、字段和分支，保留前后证据。探索时出现提醒可记录有效知识和受阻范围；异常页面的返回不能替代正常路径依据。
+4. **固化候选。** 编写有界、参数化固定实现，动态核对对象及作用域，按页面状态等待并返回结构化输出。最终实现来自已验证的操作知识，不照搬一段固定坐标或 DOM 序号录像。模型用于明确需要的理解，不逐次重新规划已知步骤。
+5. **按拟交付方式独立验证。** 对冻结版本改变关键词和目标对象，运行完整任务；检查实际页面路径、状态等待、对象选择、输出正确性、重复/失败处理及当场平台反馈。由后台记录结果，Codex 自报成功不代替固定检查和实际读回。
+6. **任务后观察并收口。** 核对官方通知和可观察的功能状态，完成下述观察记录后再评价该版本；缺口返回修订，新候选保留旧版本和旧结论。
+
+这里“像正常用户操作”落实为可见、合理的页面路径及状态转换、当前对象核对、完成反馈与有界读取。截图或画面观感只是依据之一；不以人为添加鼠标轨迹、固定延迟或技术框架名称证明平台会判为真人。
+
+#### 任务后的官方通知怎样进入验收
+
+每次正式模式验证都绑定精确候选版本和任务起止时间，并保存执行前可核对的官方通知/功能状态基线。任务结束后立即复查；另外按该测试预先配置的观察窗口和复查时点记录后续反馈。第一阶段允许维护者在后台人工登记复查结果，无需先搭后台无人值守监控。观察窗口是报告范围，不是超过该时长便绝无风险的保证。
+
+后续观察至少区分：未检查、等待复查、已检查且在该范围内未发现异常、发现相关通知/限制、关联不确定。保存可确认的通知标识或摘要、出现/查看时间、来源与关联依据；既有旧通知不误算成本次新事件，无法归因时不强行判为链路导致。渠道不可读、窗口未完成或通知关联不清时保留未知，不能记成“没有异常”。只记录与本次质量验证有关的官方反馈。
+
+“运行结果正确”“操作过程符合定义”“后续观察完成”分别检查。当前没有观察证据的版本不能据当场跑通进入用户可用清单。后续才收到相关提醒时，补记到原版本，置为待复核并暂停新的相同版本分配；以前的通过记录保留。尚无桌面安装版时，只能标记维护环境中的验证范围；未来桌面执行方式、浏览器配置或系统改变，须在对应交付环境重新验收，不能沿用不相符的旧结果。
+
+#### 通用工具的实现与平台学习的剩余准备
+
+现有代码已具备建任务、持久浏览器会话、人工确认、观察截图、不可变候选及试跑记录。本次在这些基础上补齐通用操作和维护质量规则；状态如下，不据本机夹具推断真实平台链路已可用：
+
+- **控制工具已实现：** `tools/learning/control.mjs` 为本地 Codex 提供只连接本机 API 的操作白名单，复用维护者鉴权、CSRF、任务与会话；不支持调用任意接口、脚本或命令。浏览器支持 `fill/press/click/read/scroll/wait/extract`；`press` 仅普通搜索框的 `Enter`，每个候选最多 30 步，单步滚动最多 10 次、每次最多 1600 像素，条件等待最长 15 秒。滚动可配置容器内相对 CSS 停止条件，任一完整目标出现即停止，边界或预算内未满足时明确失败；不能假定固定像素适用于不同正文。要求唯一的交互对象及精确目标零/多匹配停止，集合读取按范围与预算处理；精确目标支持任务参数，交互检查视口与遮挡。搜索控件以固定语义核对，轮换占位示例不单独作为控件变更；标签/意图真正改变或当前候选缺失仍停止，输入与按钮保留观察配额。明确点击产生的同源新页可接续控制；人工确认前同源新页可接续但不自动就绪。未知或出域弹窗暂停并显示真实阻断类型，保留最多 10 条脱敏页面事件。示例与用法见 [受限入口说明](../tools/learning/README.md)。
+- **结构化读取已实现：** 新候选契约为 v2，旧 v1 保留兼容。观察器从实际 DOM 发现普通可见 id、语义标题/容器、纵向滚动根及核对过的 id 族/安全 class 集合；每个读根最多给出 12 个实际后代的相对字段提示，并保存定位依据。安全公共祖先扫描最多 12 层且止于 body 前，集合链接仍须精确筛选和执行前再次核对唯一目标。每次按最多 12 个字段、100 行映射文本、同源 HTTP 来源或允许的业务属性；返回 `items/count/truncated/source_url/coverage`，明确当前视口和预算范围。可选完整行模式只跳过字段存在但被视口/容器裁剪的行，报告 `skipped_incomplete_count` 并标记截断；真实缺字段、敏感或多匹配仍失败，空输出仍不能通过内容验证。旧步骤不自动取得新选项。未看到或超出预算的行不能声称读完，链接中的词不能代替正文断言。更多评论层级、跨任务及更大范围的聚合去重和平台结束分支仍须分别学习，不能由通用提取器猜测。
+- **分批与空态合同已实现：** 可见等待可显式设置 `min_count`，在 1–100 个安全候选范围内等待指定可见数量；省略时保留唯一对象规则。录制/冻结继续校验集合来源，回放允许从未加载的零项等待出现，避免绑定首卡是否有标题。容器提取使用相对 `row_selector`，可配置 `batch`：先读首批，再在已观察的所属滚动根内读取最多 5 批、每次最多 1600 像素，批次时间预算 15 秒；强制完整行模式，按必填安全业务属性去重，同标识内容冲突即停止。逐批截图参与候选摘要，失败也保留已得证据；结束原因区分条数、边界、批数、时间预算，始终明确有限范围。评论父层与已展示回复须分别配置行定位，不能把平铺匹配都称为首层。另有与批次互斥的明确空态合同：普通唯一容器、零行、完整可见且精确匹配的空态文字、非忙碌和可用会话经再次核对后，才允许专用 `{"state":"empty"}` 预期通过；普通文本预期继续要求非空内容。通用工具测试与平台实际空态样本分别报告。
+- **候选和人工质量记录已实现：** 冻结清单继续绑定前后及每批证据和摘要；正式模式试跑须记录运行前基线、起止时间和观察窗口，能力详情提供直达入口，保留探索默认入口。后续观察追加到原验证与精确候选版本，保留登记时间、可选发生时间、通知引用及关联依据，数据库禁止改写或删除事实记录。详情明确提示到期时间与官方消息/搜索/详情/评论功能待办，账号本人告知实际结果后可由 Codex 代登记；运行前“正常”不替代任务后检查。当前是维护者手工核对，尚无平台专属提醒识别或无人值守观察。
+- **维护状态规则已实现：** 候选区分探索中、等待后续观察、维护范围内已验证、待复核。窗口到期本身不会通过；成功的正式模式、到期后的人工过程审核与无异常报告须同时成立。显式填写实际复查时间时，该时间也须在到期后，不能靠延后补录旧检查取得通过。晚到提醒或关联未知会影响同版本，旧试跑不能清除晚到异常，须在异常登记后开始新的正式验证并完成观察。发布预检仍 `published:false`，独立读回及未来双端交付条件保留；这里不产生商家正式可用清单。
+- **平台适配仍在验证：** 显式新 profile 按第5.10节固定动作与原生通信合同执行；旧 legacy 模式保留四类互不借用的精确实验策略，分别为搜索七条、固定标准笔记链接打开八条、普通只读辅助两条、搜索整页目标定位三条。各自限定实际目标、官网当前主框架及最长15秒窗口，原请求/到期边界和历史失败不改。新模式不把未知第一方 POST 一律拦截或认定为业务写入；两种模式均不直接请求接口，通信允许不等于结果正确，仍核对实际搜索、笔记、正文、评论与来源，实验候选也不等于正式开放。
+
+通用操作和状态规则先用隔离本机样本验证，再由维护者登录专用浏览器，与本地 Codex 协作完成首条有限真实学习。顺序为：确认会话并采集 → 观察正常搜索/详情/评论路径 → 明确必要请求及字段分支 → 记录参数化步骤 → 冻结校验 → 变参正式试跑及后续人工复查。首次观察发现现有工具不覆盖的行为时，先保留证据并补最小适配，不扩大为全站学习。

+### 14.0 当前主线：学习、固化、召回与变参执行
 
-首期由维护者与当前本地 Codex 协作，后台内置自主学习 Agent 后置。限定目标为「搜索笔记 → 详情 → 评论读取」，先完成单账号、有限样本和明确结束条件。
+当前唯一实施顺序：先完成可复用平台操作能力，再接运行时业务判断。近期对装修需求、咨询意向和人工核对投入过深，先暂停扩展这些功能，保留代码与历史。学习端不按每个行业重学网页，也不把某次内容判断固化成通用客户结论。
 
-1. **建立可确认的实际会话。** 在学习后台创建小红书批次，使用固定本地账号引用；由维护者在后台打开的专用浏览器中登录并确认当前账号。日常 Chrome 或 Codex 右侧窗口的 Cookie 不作为该会话的登录证明。
-2. **整理 Codex 可调用的工具与上下文。** 复用现有 API/浏览器工作进程，提供目标、参数、观察、动作、证据、候选与验证反馈。按实际需要补轻量操作入口，不把另建通用 Agent 平台或必须使用 MCP 作为前置。
-3. **依据真实页面完善站点适配。** Codex 观察搜索、详情、弹窗、评论展开与分页，核对定位和请求事实。当前通用只读请求限制与定位规则是否适合真实小红书需实测；失败时保存依据并修订明确的站点规则。
-4. **固化最小操作知识与版本。** 记录输入输出、字段来源、定位、等待、分支、结束条件、未覆盖项与证据；生成参数化固定实现和候选，不把一次手动点击或模型声明视为学会。

+- 已补失败留证：失败仅追加真实前后及已得批次观察、阶段与安全代码，不插入成功步骤；先核对页面再决定下一步，不将 409 等同于“什么都没发生”。记录最多 30 条被动请求摘要及 12 类去重阻止摘要，阻止总数保留，不含 query/hash、正文、头或凭据，路径敏感段泛化；旧执行器请求不可追溯补出。回放另保存受限错误码。legacy 详情历史与普通读取辅助流量采用各自有限策略；新 profile 按第5.10节固定合同核验原生通信，历史失败不改记成功。
+- 既有 legacy 修订样本输入为 `keyword` 和 `note_title`：正常首页搜索、等待至少 1 条可见标题、按标题唯一选笔记、等待详情、提取正文、首层评论分批去重，共 7 步。批次含首批最多 3 批、滚动每次 320 像素、去重输出最多 5 条，受 15 秒批次预算限制；逐批保存截图，时间/批数/条数/边界分别报告，不能据页面总数称为全部读完。旧 8 步在正式试跑发现首卡无标题导致等待超时，已转待复核；修订采用集合等待。准备阶段另发现平铺匹配会包含已展示回复，故根据实际父容器结构限定首层行。新候选静态及两组正式执行通过，实际得到 3/4 条首层评论，过程复查已登记，后续账号反馈仍等待维护者。字段缺失、目标不唯一、来源变化时停止；legacy 未匹配请求及新模式超出原生通信合同的请求分别停止，不把两种通信范围混同。
+- 下一步收集窗口到期后的官方通知/功能实查反馈，再补真实搜索无结果、评论为空、目标缺失、登录失效/验证与更多读取范围；通用明确空态合同和合成测试不能代替这些平台样本。回复展开及父子关系单独学习，业务相关性和采购意图按第 14.2 节推进，不把当前精确标题选择当作已经自动选内容。
+- 已补视口优先、离屏候选限额、隐藏正文排除与独立视口文字，以及搜索回车和明确点击产生的同源新页接续。图标和平台结构的覆盖仍须真实页面验证；提醒判断结合实际可见状态与画面，后续官方通知继续单独人工复查。已补可见页面登录检测，先检测持久会话，再决定是否需要登录或账号确认，见第 4.2 节。
+
+探索时允许记录登录失效、非真人提醒、验证码、操作频繁和权限异常，保留有效知识和中断依据；无法识别或支持的状态列为缺口。随后对冻结版本独立验证完整任务、操作路径、对象和结果，并在任务后核对官方通知及功能反馈；观察未完成、出现提醒或状态未知的版本不进入用户可用清单。恢复和重新验证按第 5.10–5.11 节执行。
+
+### 14.2 后置：保留的业务判断与自然语言验证
+
+以下业务合同和已实现记录保留，当前暂停扩展；不再把咨询分类评测或人工标注作为学习链路复用的下一步前置。完成第14.0–14.1节后再按实际运行需要验证轻量业务层：商家自然语言 → 条件解析与人工确认 → 固定选择已学搜索/阅读 → 逐源内容判断 → 条件匹配与下一步建议。学习的是可复用平台能力，业务判断每次根据当前输入和实际内容重新运行；两者独立留档。后台先验证与未来 Electron 相同的业务合同，后续桌面接输入、会话及展示，不另写一套需求判断。普通信息问答、通用 Agent、重型能力召回与桌面工程继续后置。
+
+首个业务样例已由维护者确认为“装修服务，寻找有装修需求的业主”；服务地区尚未提供，保留未设置，不自动补城市或全国范围。实施按以下顺序推进，各项当前状态分别说明：
+
+0. **已实现，验证范围有限：商家需求工作台。** 在“内容初筛”顶部提供“商家需求”入口。模型从最多 2,000 字任务文字提取平台、服务、目标客户、1–3 个搜索词、服务地区及是否排除服务推销，逐字段引用原文；缺项、范围不支持与解析失败分别返回，不自动套用装修规则或全国地区。维护者查看原文后显式确认全部条件，追加不可变确认版本，注明 `maintainer_edit`，不把人工补充伪装成模型证据。地区可明确保留未知，但后续不能判定地域已匹配。
+
+   `business_briefs` 在学习账本以 schema 8 保存解析、确认、父版本摘要、来源、提示/结构版本、配置和实际用量。解析使用与内容分析相同的可配置模型客户端、受限主备和超时策略；有效同输入/配置/版本复用，失败不自动重试。模型 Key 与供应商私有参数不进入前端。确认无需再调用模型，不原地修改草稿或旧确认。
+
+   当前确认版本只固定路由到装修样例的已学搜索和单篇评论阅读；“用于本次初筛”仅使用第一个搜索词，其他候选词保留，不自动轮询。初筛创建接口只接受候选和条数，关键词/服务/客户/地区由服务端取已确认快照；新初筛与阅读传递确认编号和摘要。仍须选择已有候选并使用其已确认会话，不自动登录或切换账号。旧结构化初筛入口保留，不能冒称已确认自然语言任务。旧阅读可显式选择新条件进行独立分析，原阅读不重写。工程假页面闭环与真实已有阅读分析分别报告；尚未据此验证任意自然语言任务或商家桌面运行。
+
+1. **首段已实现：结构化搜索、规则初筛与单篇阅读衔接。** 独立冻结四步搜索候选，读取当前有界结果的标题、作者和笔记来源；装修样例按透明规则保留最多 1–3 篇待读笔记，相关同行案例仍可作为评论来源。当前服务/客户条件限定为已支持的装修样例，其他业务不得沿用该规则冒充定制判断。按笔记 ID 归并，缺标题、重复/冲突标题、脱敏标题或非同站笔记来源不自动选择。后台“内容初筛”保存条件、规则模式、候选摘要、搜索验证、证据与全部理由，失败与历史追加留存；只保存地区条件，不作地域过滤。严格 `nonempty` 仅核对提取结构，不表示内容语义正确或已确认业主。
+
+   已补单篇阅读入口，兼容已学七步详情/首层评论链路，以及增加点击前有界目标滚动的八步修订合同：服务端只从当前初筛实际保留的笔记取得关键词、标题和编号，不接受另外传入标题或 URL。每请求一篇，绑定详情候选及其已确认会话；候选须同平台/站点，不自动切换登录。标题须唯一，滚动定位及点击前核对真实链接编号，点击后及后续读取/批次内持续核对页面编号；正文标题与来源再由后台比较。绑定输出来源去掉查询/片段，旧无绑定候选与历史不改。这里是当前浏览器内的对象核对，尚非独立身份的业务读回。
+
+   每次阅读追加 `reading_runs`，关联初筛、详情版本、实际验证、截图及错误。完整成功、正文已得但评论未完成、未完成分别保存；未学到评论空态时，零条或缺字段不能当作“平台没有评论”。评论继续按实际条数、批次、去重、结束原因和截断范围报告，不扩为全量抓取。后台可逐篇触发、查看阅读历史及直达详情，不自动重试或将实验候选发布给商家。工程、真实平台与交付状态分别以开发进度为准。
+
+   **结果重排后的定位采用独立修订合同。** 原七步第二篇因目标离开视口而停止的事实保留；新增八步在集合等待与点击之间明确加入一次 `until_target` 容器滚动。录制和静态校验绑定最新观察的唯一普通纵向容器、目标集合及已声明参数；运行时只在固定容器后代中精确匹配，与随后点击使用同一 CSS 和标题参数。目标完整可见且可操作时零滚动；否则按明确方向、距离、次数和时间移动容器。目标重复、编号不符、遮挡、来源/根变化、边界或预算耗尽时停止，不换对象或直跳来源。按步位保存实际次数、逐次位置/高度及停止原因，定位记录不代替来源核对。仅八步绑定回放在原 90 秒总预算上增加该滚动预算（最多 15 秒），单步仍限制最多 10 次、每次 1600 像素。
+
+   修订版须分别验证零滚动、搜索重排后的实际移动、目标消失和预算失败；合成测试与真实平台样本分别报告，不把新版本通过改记为旧版本成功。平台结构变化、更多结果范围与异常样本继续受候选版本约束，暂不扩大为全量读取或自动重试。
+
+   总预算还须覆盖单步执行与取证。首次八步回放暴露“只在步骤间检查”不能阻止单步越过预算，最终触发 120 秒工作进程超时、未返回完整验证。已补硬截止，并在总额内预留 2 秒关闭和返回：到期即停止本次执行并关闭其浏览器上下文，资料目录保留；只返回已完成的正文、步骤/批次证据和实际定位记录，不等待或补记迟到成功。确认关闭后后台撤销可执行状态，须重新打开并确认会话，不自动恢复。原超时阅读保留为无完整验证的失败，不据此断言页面没有发生动作。修复的工程与真实回放状态分别见开发进度；单步预算、对象绑定和旧历史继续保留，随后处理下项评论覆盖。
+
+   步骤耗时已能区分检查、读取与取证，真实媒体回放暴露逐步重复整页候选发现的成本。已将已观察定位的“当前检查”限定到该目标或滚动根，复用原元信息构造、定位语义、敏感判断、固定对象及来源核验；每步后与每批仍保留完整观察和真实截图。限定检查与原整页检查已做元信息等价及完整回归，同一冻结候选两篇追加探索通过，清单、原失败和预算未改。有限样例中当前检查成本明显下降，后置及批次取证仍占主要耗时；不能据两篇断言所有结果位置或账号都稳定，具体证据与环境见进度。
+
+   **媒体评论采用显式新内容合同。** 原文字必填遇纯图片的失败和已得批次证据保留，旧候选不改。新修订将正文声明为 `source:"content"`、`required:true`，配置已观察的普通内容根及其相对文字/媒体定位，最多保留 4 个媒体。输出区分 `text / media / mixed`，保存实际文字或 `null`、图像/视频类型、相对定位及截断事实，不返回原媒体 URL 或文件。只认实际加载、可见的正文媒体，排除头像；缺内容、加载失败、隐藏、敏感或歧义仍失败，裁剪和离屏沿用原范围语义。不能用作者或整行代正文，也不扩大完整行规则来忽略真实缺失。
+
+   媒体证据使用实际批次截图，统一标为内容未解释；存在媒体不能理解为无需求，当前不做 OCR。普通文字预期只比较原文字段，非空结构预期可确认媒体结构但不确认内容语义。新候选已覆盖真实纯文字和纯图片，混合、视频及异常分支的合成测试不能代替平台学习。实际覆盖以进度为准，未覆盖类型不冒称正式可用；模型首轮只解释实际可用文字，对媒体明确保留信息不足。
+
+   当前媒体修订样例已按实际图片位置录成独立八步：首层评论上限 6 条、每批滚动 480 像素、含首批最多 3 批，沿用 15 秒批次预算；搜索定位仍为每次 320 像素、最多 5 次、10 秒，整体绑定回放总额 100 秒。原文字样例的 5 条/320 像素及其失败均保留，各候选按自身冻结范围执行，实际条数与结束原因见进度。
+
+   新搜索页面的滚动方式须按真实观察另行修订。当前“装修公司案例”转入新的搜索页，旧容器定位未观察到，首篇在定位阶段失败且未打开笔记。新增显式 `scroll_scope:"viewport"`：定位仍绑定已观察、唯一、非敏感的普通容器，目标仅在该容器后代中匹配；实际按声明距离滚动页面，并固定核对当前文档滚动对象。页面、容器、文档滚动对象变化，目标歧义、编号不符、遮挡、不符合当前模式通信合同的请求或预算耗尽均停止。保留原次数、距离、时间及来源限制，不允许用 body/html 充当目标范围；缺省仍滚动原容器，不自动尝试另一种模式。旧候选与失败不改，整页模式的本机演示验证和真实平台复验分别报告。
+
+   **legacy 搜索分页保留独立动作阶段策略。** 实际整页移动 320 像素时，页面自然产生既有 `search_notes xhr` 请求，原通用只读策略拒绝，属于本地执行策略缺口，不据此认定平台提示或账号异常。新 `xhs-search-scroll-experimental-v1` 仅在官网精确 `/search_result` 或 `/search_result_ai` 页面、已观察唯一普通根及显式整页文字目标定位期间生效；私有绑定完整当前页面地址和签发时间，最长 15 秒、当前主框架、动作结束即撤销。只允许原 `collect xhr`、`apm_data fetch` 与精确 `search_notes xhr` 三条规则，不继承搜索历史、onebox、dqa 或笔记打开规则；不主动调用接口，不读取请求头或正文。页面/查询变化、不同发送类型、迟到或其他未知请求仍停止。后台只追加受限版本/规则标记，不保存原始请求信息。
+
+   既有 legacy 新八步为独立文字评论候选，未观察并声明的媒体类型不继承旧候选覆盖。录制时的零移动定位、正文及两条完整评论只证明各步实际来源；用于观察的额外滚动没有进入新组合，不能据此宣称完整重放已通过。首篇独立来源绑定阅读曾来源与正文通过、评论失败，保留 `partial / comments:null`；整页零移动不证明分页移动。实际批次取证约 20.4 秒，辅助 collect 请求在步骤开始约 22.5 秒后被阻止，与 15 秒边界交叉高度吻合，原日志未直接记录唯一拒因，旧失败不改。
+
+   **批次截止覆盖在途取证。** 已实现单次同步页面观察内的节点事实与原始文本遍历缓存，缓存不跨调用、页面或滚动；原筛选/排序、上限、敏感掩码、完整观察与逐批真实 PNG 保留。批次最多 15 秒，截止不晚于已签发策略到期，在上限内预留最多 2 秒关闭；到期撤销策略/ready并关闭当前上下文，`BATCH_BUDGET` 区分批次中断，只有实际关闭确认才清除后台会话。总预算先到仍为 `VERIFY_BUDGET`，不重新签发或延长授权。
+
+   每批行数据及去重计数先暂存，截图完成后，来源、固定根、登录及请求检查通过且未到期才提交。实际失败批次截图可以保留，但不能将其行数据当成完成输出。截止只保留已完整提交、逐批有证据的深复制前缀，继续标记截断与 `time_budget`，关联验证失败、阅读部分完成；未完成首批不返回评论。迟到结果不追加成功，来源漂移、内容冲突或不符合当前模式通信合同的请求，不能借部分输出绕过失败。工程回归与真实页面收益分别见进度。修复后一次真实复验的已完成后置取证约 0.25–0.30 秒，但在搜索集合等待阶段失败，不能据此宣称评论已通过或将整轮 8.141 秒与此前完整前缀 85.404 秒作同范围速度比较。
+
+   **已补加载过渡与 legacy 等待前置。** 本次搜索回车后的最新观察尚未包含结果集合；旧录制时结果已出现，不能假设未来每次如此。官网等待在进入自动化前须能按已观察定位、当前普通根和既有规则建立只读策略；否则明确 `READONLY_WAIT_NOT_READY`，不在无策略状态下继续等待再阻断页面辅助通信。敏感对象仍独立拒绝，非官网示例等待及原 body 例外不放宽。前置与下述范围等待已实现、隔离验证并加载，真实学习和回放状态见进度。
+
+   **加载过渡使用显式范围等待。** 新增可选 `wait_scope`，仅用于 `wait + visible + min_count`，须由维护者明确选取最新观察中唯一、可见、非敏感的普通读取根，不能选 body、html 或表单。目标集合可以暂为零项，但只在固定实际根内查询后代；范围外同名元素不计数，至少指定数量的可见、在视口且非忙碌对象出现才满足条件。根替换、页面完整地址或实际页面对象变化、敏感对象及超过 100 个候选均停止。后置仍做完整观察和真实截图，再核对同一根及条件；冻结引用实际根的证据，不补造缺失集合的观察。
+
+   legacy 范围等待沿用原两条只读辅助规则，按根及当前页面独立签发，不借用搜索权限；显式新 profile 仍核对相同普通根与集合条件，但按原生通信合同建立独立动作窗口，不套用这两条接口名单。`timeout_ms` 最长 15 秒，且不晚于当前策略到期，覆盖轮询、根/集合及登录检查，并在内部预留最多 2 秒关闭；到期撤销策略和 ready、关闭上下文，返回 `WAIT_TIMEOUT`，只凭实际关闭确认回传 `session_closed:true`。通用后置取证在撤销自动化与策略后执行，沿用原截图超时及整轮总预算，不把等待预算扩成整个动作预算；总截止先到仍为 `VERIFY_BUDGET`。旧步骤未声明范围时行为及证据保留，原七/八步阅读结构不变。
+
+   **legacy 实录和失败保留，当前转显式新模式验证。** 旧记录回车后集合为零、后续范围等待前已有20项，不能称真实轮询从零等到20项。旧独立回放虽建立只读策略，仍因安全状态及 APM xhr 被本地规则阻止，未得正文/评论；不能据摘要认定平台提醒或接口副作用。该失败不改写，新模式也不继承旧静态或执行结论。新增模式按第5.10节允许页面自身合约内自然通信，工具动作、来源、次数和预算仍固定；不靠延迟、改变自动化标志或换路径规避保护。
+
+   **请求拒因与失败诊断保留。** 同一纯决策函数同时服务匹配与固定拒因；legacy 四策略及其到期边界不变，新模式单独记录原生通信策略版本。拒因区分未建立/未生效、无效时间/到期、会话/页面/主框架/方法不符、地址变化或尚未开始、无效/出范围地址以及资源类型不符。只在实际阻止摘要中保存枚举原因、已签发版本及类型不符时的受限期望类型，不记录完整查询、请求头或正文。不能仅根据安全类路径判断副作用或平台是否已提示异常。
+
+   新 `failure_diagnostics` 绑定真实失败步位、动作、实际错误码和有界阶段/请求摘要，经服务端再次核验后追加到验证与其阅读；成功不带失败诊断，旧记录无字段不追溯补造。未知请求摘要最多12类，保留阻止总数及覆盖限制；总预算中断时同步快照，迟到回调不改结果。验证、阅读及动作失败共用显示，默认折叠细节，缺失原因显示未记录，不从 `WRITE_REQUEST_BLOCKED` 推断确有业务写入、平台封禁或等待超时。界面不新增放开规则或自动重试入口。失败诊断本身不改变 schema；新执行模式的可空任务字段见 schema 10。
+
+   **08–09阶段的新模式实录与历史记录（后续复用修订见14.0）。** 新任务 `learn_cbf78367730748b59da7cc0c2ec6f4f3` 共9条成功步骤；四步搜索候选 `candidate_6c67fdac11624f53b8ebb07451a5fe45` 和八步详情候选 `candidate_6c5f1066ff6d42e68c0a7e889e6061e4` 分别静态通过，详情摘要为 `e435f1973e6c6f828744e01b92dc446496b5fe6b959741d57ba0d780a30641e0`。录制定位实际整页移动0→320一次到目标；范围等待前后均18项，不称从零集合等到结果。录制评论为3批、1条完整，`truncated:true / stop_reason:batch_budget` 表示批次数上限，不是时间硬截止；这与随后回放的评论结果分别保留。
+
+   **首篇一次独立有界阅读探索通过。** `reading_d529b7e1a6db46b7801922acab373964` 关联 `validation_ff910a5ee1d74e8db51e103cdfb07d58`，模式为 `exploration`，搜索至正文/首层评论完整八步通过，来源绑定与实际新profile三字段合同一致；取得正文1条、完整首层评论2条、3批，范围截断，不代表平台全量评论。工作进程14.297秒（含入口4.488秒），服务端16.453秒，范围与计时口径分别记录；回放目标已可见、实际滚动0次，不冒称本轮验证了搜索分页。来源仍是既有 `discovery_40adbe10d64f4542b801562e4afb73bc` 的保留笔记；搜索四步候选尚未单独初筛回放，不能把详情链路搜索前缀通过当作新模式搜索初筛闭环已验收。旧来源、4条旧阅读、2个旧候选及14条旧成功步骤逐字读回不变。
+
+   **业务层历史进展与后置安排：咨询合同已有有限真实结果；当前实施顺序以第14.0节为准。** 维护者已确认两条短评论“有咨询意向，可保留为线索，实际装修需求待核实”；经同一受限入口由Codex代录的两条旧版 `corrected` 记录保留，备注注明对话确认及代录来源。旧纠错仅将表达由未知改为提问、业务相关性由不明改为相关，保持 `role:unknown / demand:insufficient / match:insufficient`，不补身份、地区或自身项目事实。正文仍未人工核对，原模型和旧五轴核对不迁移、不补新标签。
+
+   已实现有界、可追溯的笔记背景与独立 `consultation`（`yes / no / unclear`），与自身需求和业务匹配分离。服务端为同一来源绑定阅读生成 `note.context_refs=[]`、`comment_N.context_refs=["note"]`，正文只向模型提供一次，不复制到每条评论；来源仍最多21个、文字16,000字，不发空文字媒体源。每条咨询结果分别保存本源 `evidence` 和 `context_evidence:[{source_ref:"note",evidence:["笔记逐字依据"]}]`，最多一个背景来源、有依据时每类1–3条引用、单条最长1000字。yes/no须有本源依据，yes还须业务相关且有提问、求建议或自身需求表达；评论yes必须有其所关联笔记的背景依据，unclear可空。所有引用按对应来源逐字核对，其他评论、外部来源、未声明输出及动作字段均拒绝。服务正文可帮助理解联系方式短句的咨询对象和相关性，作者或其他评论者的需求、项目地区、预算和身份不能继承为本评论者自身事实。
+
+   新提示/结果为 `renovation-demand-v4 / demand-result-v3`，保存独立追加分析，复用要求版本、阅读、配置和商家条件均一致，旧分析不能被当作新版本完成。程序仅派生 `lead_disposition:retain_for_review / not_selected / insufficient` 和有限展示建议；业务相关、未按商家条件排除的咨询yes或自身需求可保留待核，不把咨询、相关性或“保留”升级为已确认需求、客户身份、地区及 `match`。咨询yes且原建议为跳过或补信息时，改为 `review_consultation`；模型不能直接输出动作计划。新字段保存在现有JSON分析/核对事实中，无数据库schema变更或线索表，也不引入完整A2A、自主Agent或联系动作。
+
+   代码、离线合同及已保存两条标注的合同验证已完成；离线检查没有模型、API或数据库调用，不是语义质量评测。服务已受控重启加载，只对同一已保存阅读创建独立新分析，没有重读平台。首轮真实模型输出未通过合同，失败原样保留；新增仅含固定检查枚举的无文本诊断后，后续独立调用完成，将两条评论判为咨询yes并保留待核实，同时自身需求、身份、地区和匹配继续不足。后续未重现首次失败，不能据此确定首次具体拒因或宣称修复了该原因。旧阅读、分析、两条人工核对及步骤逐字读回不变，新分析没有自动继承人工标签。后续恢复业务层验证时，再用固定评测集补服务推广、单纯赞美、询问他人进展等正反例及真实标注，分别核对咨询与自身需求，保留无效输出；有限同向样本不作整体准确率或稳定性验收。新四步搜索候选的独立验证、新来源衔接与正式基线已前移至第14.0–14.1节，先于业务分类扩展；不自动重读、扩第二篇或执行联系。浏览器已受控关闭且未重开，本轮分析不需要重新扫码或确认平台账号；平台链路、正式基线、账号后续反馈及Windows/macOS桌面交付仍分别验收，尚未发布。
+
+   新输出合同失败仅在实际新记录中可保存 `output_diagnostics:{check}`：枚举限定来源图、旧字段/覆盖/引文/角色/表达/自身需求/相关性/事实，以及咨询字段/值/依据/背景/组合，共16类。允许范围和 `MODEL_OUTPUT_INVALID` 不变，不保存原始模型输出、来源编号、URL或私有错误；缺失原因不追溯补造，成功不带失败诊断。它只定位固定检查，不证明语义正确，也不触发自动重试或切换模型。
+
+   修订候选可显式选择本任务已记录成功的真实步骤编号，1–30 个、不得重复、按声明顺序冻结，保存 `source_step_ids` 及完整动作前后/批次证据引用；不接受客户端另造步骤、修改原步骤或传入原始清单。未知、异任务、空或重复编号拒绝且不创建候选；缺省全步骤行为兼容保留。选步后的新版本仍须独立静态检查、合同核对和完整回放，不继承旧验证或质量结论；证据闭合不代表重新组合后的前置条件和时序已经跑通。
+
+   步骤耗时保存为受限 `step_timings`，含步位、动作、完成/失败/中断、实际毫秒数及独占阶段。当前检查、目标解析、执行、就绪等待、请求核验和前后/失败/批次截图分别记录；未发生阶段和旧记录不补零。`verify_timing` 保存总、入口与关闭耗时，未尝试关闭为 `null`。中断保留真实前缀和已得结果，返回数组值复制，迟到回调不补成功；不采集页面文字或参数作计时标签。按实际阶段成本优化，不靠扩大已有预算证明成功。本次已基于来源核对通过的有界文字进入第2项独立需求判断；模型只使用实际可用内容与明确缺失信息，运行通过不替代业务核对。
+2. **已接入，当前验证业务质量：独立、可追溯的模型需求与咨询分析。** 当前代码提示为 `renovation-demand-v4`、结果为 `demand-result-v3`，咨询及背景合同见上文；旧 `renovation-demand-v3 / demand-result-v2` 分析保留。分别保存当前发言角色信号、可多选表达、自身需求、业务相关性及独立咨询意向；例如“我家准备装修，问大家顺序”同时属于自身明确需求、提问和求建议。“哪里”不足以确认服务方，服务方也可同时有自身需求，不能按账号角色一刀切排除。普通讨论、提供/推荐服务、已完工分享和单纯赞美不自动成为发言者自身需求。阶段、地区、预算只提取该发言者自身项目的原文事实，不把设计师所在地当作客户项目地。原版本结果保留，歧义仍待标注，不作账号身份或客户确认。
+
+   服务端根据当前确认条件及已校验判断固定派生初步匹配、保留待核、理由和建议；模型不输出可执行浏览器计划或跟进文案。地区未设置、缺项目地区或地名用词不同均保留待核，不擅自做行政区包含或判定异地不匹配；仅明确选择不限地区才跳过地域条件。排除服务推广只排除无自身需求的当前提供服务表达，不屏蔽服务方自身需求，也不丢弃同行笔记下面的潜在需求评论。建议区分核对作者、核对评论者、核对咨询意向、查看评论、补充信息和跳过，当前均为展示，关注/私信/评论不可执行。
+
+   分析只取来源核对通过、已有可用正文的完整或部分阅读，不重新操作平台，也不接受客户端另传文字、标题或来源。分析作为独立追加事实绑定阅读摘要、商家条件快照/摘要、模型配置、提示/结果版本与实际输入来源，复用键包括业务上下文；变更条件不会误用旧匹配结果。阅读已绑定确认条件时默认继承；旧 `POST {}` 沿用原初筛条件并明确来源，不冒称维护者确认。旧初筛、阅读及其“未调用模型”字段保留。模型只接收有限文字、临时来源引用和必要业务条件，不接收作者、真实对象 ID、链接、页面图像或凭据；页面文本按非可信资料处理，不能改变分析任务或触发工具。
+
+   服务端核对每项来源、结果覆盖、固定分类和逐字证据；阶段、地区和预算的值及依据均须来自对应原文。纯媒体由程序标为信息不足、内容未解释；缺失、裁剪及部分阅读范围明确保留，不能自动补完身份或将结论当作已确认客户。首轮最多 21 个来源、16,000 字，超限拒绝且不调用模型；不悄悄截断后声称完整覆盖。结构正确和引用真实只能证明结果可追溯，不能证明分类准确率。
+
+   安全状态、分析触发、逐条依据、主备尝试、Token、固定失败及历史已通过独立 API/UI 展示；不暴露密钥、接口私有参数或提供商原始错误。历史“查看分析”使用独立打开状态，每次点击直接展示详情侧栏，同条关闭后可重开；分类与原文依据优先，技术配置及用量折叠。打开和切换历史只改变界面，不调用模型或修改分析；人工核对另按下项显式保存，查看和预填不算已经核验。
+
+   隔离提供商与PostgreSQL回归、既有阅读的有限调用保留。旧 `analysis_aae778abf4c5410aae59a9089c016ec4` 采用v3提示/v2结果，主槽 `deepseek-flash` 一次完成，约2250毫秒、1822 Token，实付金额未知。正文服务推广的模型判断引导查看评论；两条联系方式短评论的原模型 `insufficient / role:unknown` 保留。维护者已确认咨询意向，两条旧人工纠错只调整提问表达及业务相关性，自身需求、角色、匹配和地区仍待核实；不据此修改默认型号或将人工意见一致性当作分类准确率。新上下文和独立咨询意向代码已实现，真实模型分析另存修订且不迁移该旧标注；后续型号对比仍用同一标注集分别评估漏判、误判、耗时和成本。
+3. **已接入五/六轴人工核对，下一步积累真实样本。** 完成的v2分析使用原五轴，完成的v3分析增加独立咨询意向为六轴；详情提供醒目“人工核对”和每源入口，原文、笔记背景、原模型标签与人工结果分开显示。维护者显式选择“判断正确”“需要修正”“暂不能确定”或“当前文字不可核对”；首次预填原标签但不预选决策，也不自动保存。修正需实际改变当前版本至少一轴，并填写说明和1–3条本来源逐字引用。新版yes/no咨询须有本源依据，评论yes还需关联笔记逐字背景依据；不确定/无法核对须清空标签和背景依据并写原因。不能凭咨询意向补身份、需求或地区，不能将未知地区修成已匹配；纯媒体只有后两种未判定状态，不借文字核对冒充图像理解。
+
+   `analysis_reviews` 沿用schema 9追加表：v2分析继续保存 `analysis-review-v1` 五轴，v3分析保存 `analysis-review-v2` 六轴及独立 `context_evidence`。均保存原分析/来源摘要、原模型标签、维护者、决策、人工标签、依据、说明及前版引用；原分析、来源和旧核对均不修改，新合同无需schema变更。旧v2请求不接受新增咨询/背景字段，更早或失败结果只读，不补造维度或允许不完整结果晋级。每个来源修订追加版本，按原先读到的最新编号做事务核对；并发或旧表单409后刷新并要求重新核对，不自动重发。明确422校验拒绝显示安全原因并允许继续修改；成功、校验及冲突反馈自动滚入核对侧栏视野，避免长表单只看到禁用按钮。API与维护入口沿用鉴权、归属和CSRF，不调用模型或操作平台。
+
+   统计每个来源最新版本：已保存核对/待核对、已判定、正确/纠错、暂不能确定/文字不可核对分别计算，修订历史不重复计数。一致率只以“判断正确 + 需要修正”的已判定样本为分母，无样本为未知；另列各轴差异数。界面展示原模型结果，这是辅助核对一致性，不能称为独立评测准确率、精确率或召回率，更不能将暂不能确定、媒体、未核对项算作正确或错误。
+
+   首批核对范围为第一篇正文及两条有歧义评论。可在界面显式保存，或由用户在对话中确认已展示的具体来源和判断后，通过同一受限入口由 Codex 代录，备注注明对话确认和代录来源；不能根据一般业务讨论推定其他样本结论，也不能伪装成用户点击界面或独立盲标。首批三项已保存：正文确认、首条评论仅纠正表达类型，第二条评论由用户选择上下文不足并保留不确定；只有前两项计入已判定，角色、地域与需求缺失不强行补齐。这三项仅作有限质量对照，程序与 Codex 不代作余项真实人工判断。随后补地区、服务方兼具自身需求、同行内容下需求者等有限真实样本，形成独立标注集后再评估误判、漏判、费用和默认模型；不据这两项已判定样本直接修改默认模型或宣称准确率，业务样例的质量核对后置于平台链路复用验证，不能据此阻断行业无关的操作能力建设。线索归并、普通信息问答及新业务单独评估，关注、私信及回复仍按第 14.3 节单独学习。
+
+   “案例或服务展示内容→评论者自身需求”分支已取得新模式首篇服务推广正文及两条联系方式短评论，并完成旧版独立模型分析。两条旧版人工纠错已保存：`review_3edb0c3a1ca54a468e30870174150e86`（`comment_1`）、`review_ade9c9f4b0f649d6844019eb6a8d4e98`（`comment_2`），均注明维护者对话确认、Codex代录；可保留待核实咨询意向，不确认实际装修需求、身份或地区。该旧分析3个来源中已核对2个、待核对1个（正文），已判定2个；原模型完整读回不变。它的五轴备注不冒充新咨询状态，也不迁移成新版本人工标注；新合同代码和离线验证已实现，真实新分析及其业务质量另行验收。独立咨询展示不等于线索库，不将有咨询意向、正文服务推广或有限阅读通过当成本分支自身需求质量已经验收。
+
+当前标题规则只用于验证发现与初筛流程。真实“装修案例”搜索中，部分相关内容标题并不含装修词，规则没有保留，不能据此断言平台没有合适内容或客户；后续需结合正文、评论与标注样本评估漏判。公开笔记编号与手机号须按字段语义处理：只对已核验官网的标准笔记来源路径保留公共编号，敏感查询、片段及普通文本继续脱敏，不改写历史记录。
+
+### 14.3 再后：关注、私信及评论回复
+
+先补写操作的范围、测试对象、对象/评论层级核验、独立结果核对及去重，再按已有授权执行限定测试。每种动作单独验收，分别处理已关注、已发送、评论层级不符、平台阻断和结果未知。正常步骤由固定链路控制，模型只在明确需要时处理内容；未知结果不自动重发。
+
+### 14.4 按规模扩展检索与交付
+
+能力目录扩大或简单路由出现可复现不足后，再按需要采用正向能力文档、BM25/向量融合和独立召回评测；历史内容/线索检索单独定义对象和范围。已有检索扩展保留，模型和索引配置届时按实际方案验证。
+
+平台链路与业务质量稳定后，再恢复 Electron 商家端、双端安装/升级及商业网关。未来 Windows/macOS 仍须分别验证相同业务范围；当前后台验证不替代双端交付，也不要求现在建设完整桌面或 A2A 调度体系。
+
+已确定的优化更新本节或其所属章节，说明问题、顺序和验收依据；进度记录引用当前规划。一般解释问答不新增计划。

-# 本机学习浏览器工作进程
+# 本机协作学习入口
 
-维护后台通过标准输入输出的逐行 JSON 调用此 Node.js 进程。浏览器、登录资料和截图在维护者本机，工作进程不会调用模型或存储平台密码。
+由维护者在学习后台创建任务、打开专用浏览器并完成官方页面登录。本地 Codex 可通过本目录的受限控制入口继续观察和记录，所有动作绑定后台中的任务与会话，不另开一份账号资料。这里没有通用自主 Agent。
 
-输入为 `{ "id": "request-id", "method": "capture", "params": { "task_id": "task-id" } }`。输出为相同 `id` 的 `result`，或包含 `message`、`code` 的 `error`。标准输出只用于协议，进程按顺序处理请求。
+入口只连接本机维护 API，复用后台鉴权、CSRF、动作预算和证据记录。维护者账号通过当前进程的 `ASSISTANT_MAINTAINER_USERNAME`、`ASSISTANT_MAINTAINER_PASSWORD` 环境变量提供；不要放入命令行参数、任务内容或版本库。`ASSISTANT_CONTROL_URL` 默认为 `http://127.0.0.1:8810`，仅接受本机 HTTP 地址。平台的手机号、密码、验证码不经过此入口。
 
-关闭标准输入或标准输出管道断开会立即关闭浏览器上下文，使执行中的试跑自然中断；所有关闭入口等待同一个清理过程，不会重放动作。调用方应等待工作进程实际退出，再重开同一资料目录。
+标准输入为一个 JSON 请求，或最多 30 个请求的数组；一次输入不超过 64 KiB。标准输出为 JSON 结果。顺序执行遇错即停，已经完成的动作会保留，超时和失败不自动重放。`health` 不需要维护者凭据：
 
-## 方法
-
-- `open`：传入 `task_id`、`account_key`、`entry_url`，打开固定账号资料目录，进入等待人工登录与确认阶段。
-- `ready`：传入 `identity_label`，明确记录维护者人工确认。首版没有自动平台身份核验器，不能把该记录解释为自动认证成功。
-- `capture`：采集已确认页面的文本、候选定位和视口截图，返回 `capture_id` 与证据路径。
-- `action`：执行最近一次采集中的 `fill`、`click`、`read`。定位重新核验；普通动作要求唯一目标。
-- `verify`：从入口运行已生成的固定步骤，用参数替换填写值，核对指定输出文本并保存实际页面证据。
-- `close`：关闭会话、释放账号占用，保留资料目录。
-- `status`：查询当前会话是 `awaiting_user`、`observing` 还是 `closed`。
-
-## 配置与边界
-
-- `ASSISTANT_LEARNING_HOME`：学习资料根目录，默认 `.runtime/learning`。账号目录使用入口 origin 与 `account_key` 的固定 SHA-256 标识；同账号不能被不同活跃任务同时使用。
-- `ASSISTANT_BROWSER_CHANNEL`：浏览器通道，默认 `chromium`。开发机可指定已安装的 `msedge`；无浏览器时返回明确错误，不自动下载安装。
-- `ASSISTANT_BROWSER_HEADLESS=1`：仅供隔离验收使用。正常维护登录使用有头浏览器。
-- 首版限制在入口的同一 origin，尚不支持跨域 SSO 跳转；需扩展站点范围时先补明确的范围契约。
-- 首版操作只涵盖普通文本填写、同站点链接、明确的搜索与展开按钮及读取；关注、私信、发送、提交、支付、删除不在运行范围内。自动步骤期间拦截非 GET/HEAD/OPTIONS 请求。
-- 人工确认前不采集页面；采集跳过敏感表单和输入值，截图遮盖输入区。手机号、验证码、密码不得作为步骤参数或人工确认标签。
-- 验证至少需要一个非空输出预期。结果中 `os`、浏览器版本和时间由实际执行进程生成，失败不会被记录成通过。

-安装项目依赖及相应浏览器后运行：
-
-```text
-node tools/learning/test-browser-worker.mjs
+```powershell
+'{"operation":"health"}' | pnpm --silent learning:control
 ```
 
-Windows 默认使用已安装的 Edge，其他系统默认使用 Playwright Chromium，可通过 `ASSISTANT_BROWSER_CHANNEL` 覆盖。脚本启动仅绑定回环地址的临时页面，以独立子进程通过真实 JSONL 协议调用工作进程，不访问内容平台、模型或商家数据库。
+已有任务的观察与操作示例（替换任务 ID，并在当前进程配置维护者凭据）：
 
-测试使用工作区 `.tmp/worker-regression-*` 下的新资料目录，覆盖人工确认门禁、账号互斥、敏感字段过滤、发送阻止、参数化实际读回、错误及空预期、关闭重开 Cookie 复用、协议错误恢复、关闭状态，以及试跑中收到 EOF 后及时退出并由新进程重开原资料目录。成功后清理本轮目录；失败时保留证据。加 `--keep-artifacts` 可保留成功证据和 `report.json`。
+```json
+[
+  {"operation":"tasks.get","task_id":"learn_example"},
+  {"operation":"browser.capture","task_id":"learn_example","data":{"note":"读取当前页面"}},
+  {"operation":"browser.action","task_id":"learn_example","data":{"kind":"scroll","selector":"body","direction":"down","pixels":500,"max_scrolls":1}}
+]
+```
 
-界面中，“固定规则校验”可独立执行；“浏览器试跑”要求该学习任务已打开会话并由维护者人工确认当前账号。关闭后重新打开仍要确认，不能把持久化 Cookie 或上次确认视为当前账号自动核验结果。
+将 JSON 文件作为标准输入执行 `node tools/learning/control.mjs`。需要先查看页面证据，再选择其中的 CSS 定位，不能从示例推断真实平台定位。操作集合为：
+
+- `tasks.list / get / create`：学习任务。
+- `browser.open / ready / capture / action / close`：专用会话、人工确认、证据和动作。
+- `candidates.create / get / check / verify / publish_check`：冻结候选、固定校验、试跑及发布预检。
+- `validations.list`：验证账本。
+- `quality.append`：向指定 `validation_id` 追加人工观察，后台保留历史和时间门禁。
+- `routes.list / resolve / verify`：与行业无关的学习候选目录、固定版本召回和变参组合验证。`resolve` 只读选择，`verify` 使用已确认会话串行执行搜索和一篇详情/评论，不调用业务模型；失败不自动重放，汇总留在现有验证记录。
+- `discovery.list / get / create`：装修内容初筛历史、指定 `run_id` 详情及新建；新建复用已确认会话和冻结搜索候选，失败不自动重试。
+- `readings.list / get / create`：指定初筛 `run_id` 的阅读历史、指定 `reading_id` 详情，以及单篇阅读；新建 `data` 仅传 `detail_candidate_id` 和该初筛实际保留的 `note_id`，标题/URL/关键词由后台取原记录。
+- `model.config`：需求分析的安全配置状态，不返回接口地址或 Key；已配置不等于已验证连通。
+- `reviews.list / create / summary / get`：指定 `analysis_id` 的核对历史、显式追加核对、按每源最新版本统计，以及按 `review_id` 查看。只保存维护者判断，不调用模型、重读平台或覆盖原分析。
+- `briefs.list / get / create / confirm / discover`：商家需求历史、按 `brief_id` 读取、由 `data.request_text` 解析草稿、显式确认完整条件，以及用确认版本初筛。`discover` 仅接受 `search_candidate_id/max_selected`，使用确认条件的第一个搜索词，不接收条件覆盖；不会自动调度其他搜索词或开启浏览器。
+- `analyses.list / create`：指定 `reading_id` 的分析历史或新分析；新建仅传空 `data:{}`，不接受外部正文/标题/来源。`analyses.get` 以 `analysis_id` 读取独立事实。
+
+## 固定执行模式与实际合同
+
+学习与未来 Electron 桌面共用 Playwright 固定步骤和同一执行协议，不另建 browser-use `Agent.run` 路径。新小红书任务默认“有界网页操作（原生通信）”；受限入口 `tasks.create` 可显式传 `execution_profile:"playwright-xhs-native-ui-v1"`。省略仍为 legacy，旧任务不会自动升级；其他平台不能使用这个小红书 profile。没有任意框架名或自定义策略配置入口。
+
+新模式固定合同为 `execution_contract:{engine:"playwright",action_policy:"xhs-bounded-readonly-v1",network_policy:"xhs-page-native-v1"}`，三字段和值须完全一致。任务顶层 profile 只是选定模式；`browser_readiness` 中的 profile/contract 来自当前已核验会话，未打开会话不填。`open/status/ready` 原始响应也回显实际合同；候选 `manifest` 保存冻结配置，浏览器验证 `environment` 保存执行器实际返回值，初筛和阅读复制各自验证的实际合同。旧记录缺字段不补造，固定规则校验合同不冒充已实际运行；错配停止，不降级为 legacy。
+
+schema 10 仅新增可空任务 `execution_profile`，旧值保持空且 API 省略。新模式候选必须以该模式实际记录的成功步骤和证据独立冻结，不把旧步骤或旧验证改写为新模式通过。当前新模式已完成9条成功实录，搜索四步和详情八步候选分别静态通过；详情候选一次独立探索回放取得正文1条、首层评论2条及正确实际合同，读取范围仍截断。09阶段搜索四步尚未独立初筛回放，笔记来源沿用既有初筛。10阶段已通过通用组合独立搜索取得新来源，再用新七步修订读得正文和有限评论；两个阶段分别留档。两条短评论已按维护者对话确认由Codex代录旧版五轴纠错，保留为待核实咨询意向，但不确认自身装修需求、身份或地区，正文仍未人工核对。原模型和核对保持不变。新上下文、咨询意向及六轴核对合同已实现并完成离线目标验证；当前服务已加载，新版本后续独立真实分析取得两条咨询yes且保留待核实的结果，需求、身份、地区及匹配仍未确认；首轮输出合同失败保留、原因未重现，未建立线索库。当前暂停扩展上述业务识别；通用轻量路由、隔离变参与一个真实新词组合探索已通过，接下来按整体方案第14.0–14.1节补更多范围及正式运行反馈；不自动重读或执行联系。
+
+新模式的动作只允许官网声明页面内已观察且当前唯一可用的搜索输入/`Enter`、已固定实际对象的同站标准笔记锚点，以及普通非交互、不可编辑、非敏感区域的有界读取、等待和滚动。点击前后核对笔记编号，搜索提交后核对实际关键词结果页，读取持续核对页面来源、根及输出；关注、私信、评论输入和发布不在该合同内。
+
+网页自身通信与上述工具动作分别约束。最长15秒的当前动作窗口内，当前主框架自然发起、无凭据URL且标准端口的第一方 HTTPS（`xiaohongshu.com` 或其子域）`xhr/fetch POST` 正常通信，包括页面安全通信，不再用逐接口名单判断其业务副作用。非第一方、子框架、其他需策略授权的方法、非HTTPS、其他资源类型、来源漂移或窗口过期仍拒绝；窗口不续签，动作结束撤销。只允许搜索转入同关键词结果页、点击进入固定笔记这两类已声明来源转换。
+
+这不是网络沙箱，也不证明第一方请求绝无服务端副作用；不直接调用平台 API、不执行任意 JavaScript、不读取请求头/正文，不加指纹伪装或防检测策略。不能据通信允许判定动作成功，也不能据本地阻断认定平台提醒或账号权重；仍以真实页面结果、来源、截图及任务后人工反馈分别核验。GET/HEAD/OPTIONS 等原有被动通信规则不因本模式被改称“所有网络请求均受隔离”。
+
+动作支持 `fill / press / click / read / scroll / wait / extract`。`press` 只允许已观察的普通搜索框按一次 `Enter`，不接受任意按键、评论输入框或 POST 表单。滚动有次数和距离上限，等待有明确条件和超时，动态对象可用文本、来源链接或允许的业务属性精确匹配；多匹配或无匹配时停止。结构化提取按相对 CSS 字段映射读取文本、同源 HTTP 链接或允许的业务属性，并报告本次范围。不能执行任意 JavaScript、任意接口或读取登录凭据。实际字段约束由 `action-contract.mjs` 与后台契约校验。
+
+`candidates.create` 的 `data` 可传 `{name,step_ids:["step_..."]}`。显式选步须为本任务已有的 1–30 个唯一成功步骤编号，按传入顺序冻结；新清单保存 `source_step_ids` 和原步骤完整证据，不接受原始清单或字段覆盖。省略 `step_ids` 仍冻结全部步骤。新组合不继承旧候选验证，须重新检查和回放；选步证据完整不代表新顺序的前置条件已通过。
+
+`scroll.until_selector` 为可选的容器内相对 CSS 条件，目标完整可见时停止，可为 0 次；条件仍受实际滚动次数、距离和等待预算限制，边界内未满足时保留失败证据。`extract.complete_only:true` 只跳过字段真实存在但尚未完整进入视口/裁剪范围的行，返回 `skipped_incomplete_count`，遗漏时 `truncated:true`。真实缺字段、敏感或多匹配不能靠此选项通过，空输出也不能通过内容断言。两个选项分别仅适用滚动/提取，省略时保持旧合同，已有候选不会被改写。
+
+可见等待可显式设置 `min_count:1..100`，等待集合中达到指定数量的可见对象；默认省略仍要求唯一目标。录制和冻结检查仍绑定实际观察到的集合证据；回放允许结果尚未加载时从零项开始等待，实际出现的对象逐次检查，敏感对象、过大范围、超时或未授权请求仍失败。
+
+容器内提取使用 `selector` 指向已观察的唯一普通容器，另设相对 `row_selector`。可选 `batch:{scroll_selector,pixels,max_batches,dedupe_field}` 先读取首批，再向下有界滚动；最多 5 批（含首批），每次 1–1600 像素，批次时间预算 15 秒。必须启用完整行模式，以声明为必填的安全 `id/data-*` 业务属性去重；同一标识内容冲突时失败，不能静默覆盖。滚动根须为已观察的普通纵向滚动容器，属于读取容器且包含所有目标行；来源或根对象变化立即停止。每批都有真实截图引用，成功步骤的 `batch_evidence_ids` 参与候选摘要，部分失败也保留已得证据。输出额外含 `batch_summary`，结束原因区分条数、边界、批数和时间预算；始终标记有界范围，零新增不等于已读完。裁剪跳过计数是各批行观察次数，不能当作唯一评论数。
+
+明确空态使用 `allow_empty:true` 和容器内 `empty_state:{selector,text}`，与批次模式互斥。只有行数为零、唯一普通空态文字精确匹配且完整可见、容器非忙碌、会话可用并经短时再次核对，才返回确认空态；输出附 `empty_state:{confirmed:true,selector,text}`。预期结果必须显式写为 `{"state":"empty"}` 才能通过空态断言；普通文本预期仍要求真实非空内容。单纯零匹配、尚未加载、退出登录、验证页面、裁剪或去重后零新增均不能当作正常空态。平台实际空态定位需要另外学习，不能直接套用本机示例。
+
+搜索初筛使用严格的 `{"state":"nonempty"}` 结构预期，仅适用于合法 `extract` 输出：条数大于零、字段及必填值、来源和批次元数据须符合合同。它不判断标题语义、作者身份或采购意图；可选标题缺失时即使结构验证通过，业务层仍不自动选择该笔记。
+
+新修订可将评论正文明确声明为 `source:"content"`，同时配置内容根 `selector`（省略表示当前行）、根内 `text_selector`、`media_selector` 及 `max_media:1..4`，并保持 `required:true`。媒体定位须根据实际观察选择正文区域，不能把头像当作评论内容。文字可以不存在，但必须有实际可读文字或已加载、可见的图像/视频；真正缺内容、未加载、敏感或歧义仍失败，裁剪与离屏按原完整行规则处理。旧 `source:"text"` 不能携带这些新选项，原文字必填语义不变。
+
+此时 `body` 是 `{kind,text,media,media_truncated}`：`kind` 为 `text / media / mixed`，无文字时 `text:null`，媒体条目仅含 `kind:image|video` 与内容根内相对 CSS。超出媒体上限会明确截断，不返回媒体 URL、替代文字或原媒体文件，也不做 OCR。真实证据使用同批截图；“存在媒体”表示内容未解释，不能推断无需求。`nonempty` 只核对该结构，普通文字预期只比较真实文字，不使用媒体类型或 CSS 充当内容。
+
+来源链接与普通文本分别脱敏：仅 `https://www.xiaohongshu.com` 无凭据、标准端口、精确 `/explore/{24hex}` 或 `/search_result/{24hex}` 的公开笔记路径保留编号，防止编号中的连续数字被误当手机号；查询/片段及其他 URL、普通文本仍按原规则处理。后台接收浏览器文本时仅修复无效 UTF-16 片段，防止长文本截断表情导致 UTF-8 保存失败，合法 Unicode 和历史摘要保持不变。
+
+`discovery.create` 的 `data` 为 `{search_candidate_id,keyword,service,target_customer,region,max_selected}`。当前为装修样例，使用“填写关键词 → 搜索回车 → 可见集合等待 → search_results 提取”四步合同，输出标题/作者（可选）和笔记链接（必填）。地区为空不推断；最多保留 1–3 篇，保存规则模式、冻结摘要、验证、证据与未选理由。无会话时保存失败记录，不自动开启浏览器。新记录追加保存，历史不随规则变更重算；随后由单篇阅读入口接续正文/评论，再以独立分析入口处理文字需求，联系动作尚未接入。
+
+单篇阅读支持已有七步详情候选，以及在点击前增加一次有界目标滚动的八步修订合同，使用其已确认会话，一次请求只读一篇并单独保存。后台只信任初筛 `selected` 中的编号/标题/来源。可选 `note_binding:{note_id}` 仅允许这两种合同：滚动定位及唯一标题点击前核对实际链接 ID，点击后、读取前后和每批检查当前页面 ID；输出的 `note_binding_result` 五项为 `note_id/href_checked/url_checked/source_url/title`。绑定时两个提取输出与核对记录的来源均为实际 origin + pathname，不含查询/片段；截图 URL 仍按原规则脱敏，无绑定的旧执行语义不变。后台再次比对实际编号、标题与提取来源并记录 `note_source_binding` 断言；这不是独立身份的业务读回。
+
+八步合同为 `fill → press → wait → scroll → click → wait → extract → extract`。目标滚动须声明已观察、唯一的普通纵向容器，以及 `until_target:{selector,field,parameter}`（或固定 `value`），并设置 `direction/pixels/max_scrolls/timeout_ms`。目标仅在固定容器后代中匹配，定位与随后点击使用相同 CSS 和目标参数；与 `until_selector` 互斥，不允许整个 body 作为该步骤根。目标已经完整可见且可操作时可以零滚动；否则只按声明距离移动当前容器，在次数、时间或边界内未找到就失败，不更换对象或直跳详情链接。重复目标、编号不符、遮挡、来源/根变化均停止。
+
+整页滚动的页面可在该有界目标动作中显式加入 `scroll_scope:"viewport"`。`selector` 仍是已观察、唯一、非敏感的普通容器，目标仅在其后代中寻找，不能使用 body/html；实际移动固定的 `document.scrollingElement` 所对应页面视口。普通容器可以没有自己的滚动条，但当前及前次视口元信息须有效，页面、根容器和文档滚动对象均持续核对，实际位移按相同次数、距离和时间预算保存。该字段不能用于普通滚动、等待、批次提取或无 `until_target` 的动作，不隐式切换；省略时旧容器滚动语义不变。后台录制表单提供“滚动整页寻找容器内目标”，历史摘要显示“整页”。
+
+回放的 `seek_results` 按步骤保存实际滚动次数、逐次位置/高度、是否找到和停止原因，不保存匹配原文或账号数据，也不代替来源绑定。已有七步候选省略该字段，旧候选与失败不改写。仅八步绑定回放在原 90 秒总预算上增加声明的滚动预算（最多 15 秒），不扩大其他动作或工作进程调用上限；单步滚动预算仍最多 10 次、每次 1600 像素、15 秒。总预算覆盖动作和取证，到期关闭本次浏览器上下文并返回 `VERIFY_BUDGET` 及已完成的内容、证据和定位记录；确认关闭后撤销后台就绪状态，资料保留，重新运行须先打开并确认会话，不自动续跑。真实平台样本与工程测试分别见开发进度。
+
+阅读记录状态区分 `completed / partial / failed`。只有对象核对通过的正文才能作为本篇内容展示；评论失败时可保留已得正文和真实证据。旧文字必填合同遇到纯图片/表情仍会失败，不能用作者或整行冒充正文，也不靠完整行模式跳过真实缺文字；新内容合同须另录候选，平台图像/视频的实际覆盖分别见进度。未学习评论空态的候选仍以非空合同验证，零条/缺字段不当作“确认无评论”。可用 `#/discovery/{run_id}?reading={reading_id}` 回看；跨初筛或失效阅读 ID 不展示错归属结果。超时/失败后先查阅读历史与验证，不自动重试。
+
+明确点击产生的同源新窗口可接续为当前页面；人工确认前的同源新页可接续，但仍须确认后才能采集。未知或出域弹窗关闭并暂停，`block_reason` 说明实际阻断，不能仅显示登录确认。最多保留 10 条脱敏 `popup_observations` 页面事件，不将未知来源伪装成网络请求。
+
+动作失败会保留真实前后观察与安全诊断，`source:action_failure` 不算成功步骤。诊断最多 12 类被阻止请求摘要，按方法、来源、泛化路径和资源类型去重，阻止总数保留；观察另含最多 30 条新执行器运行期间的被动请求摘要。不保存查询参数、请求体、请求头或凭据，不追溯补写旧执行器的请求。
+
+新执行器的被阻止摘要另附固定 `policy_reason`，可选 `active_policy_version` 及仅资源类型不符时的 `expected_resource_types`；相同请求与拒因去重。它解释当前本地策略决定，不能证明接口副作用或平台已发出提醒。`evaluatePlatformRequest` 与原 `matchPlatformRequest` 共享判断；legacy 四类版本和原到期边界不变，新模式按上节独立合同判断。自动动作结束后页面恢复普通通信，不能将本步阻止解释为所有后续通信仍持续被阻止。
+
+失败回放可返回 `failure_diagnostics:{step_position,kind,code,diagnostics}`，诊断包括原受限阶段、阻止总数及最多12类摘要。服务端核对步位/动作/实际错误码，只在真实失败时追加保存到验证和阅读；非法字段丢弃，成功和旧记录缺省不补。总截止同步深复制当时状态，不等待额外诊断或接受迟到成功。后台验证和阅读详情显示失败概要并折叠摘要；旧记录明确未记录，不由错误码猜具体拒因，无放开规则或重试入口。新代码的加载和真实验证状态以进度为准。
+
+## legacy 实验请求模式
+
+以下四类策略只描述未声明新 profile 的旧模式，用于历史复现及对照，不套用到原生通信模式。`platform-policy.mjs` 保留四类实验策略，均限定小红书官网、当前主框架、经现有固定检查核验的实际目标及最长 15 秒动作窗口：`xhs-search-experimental-v3` 允许搜索框填写/回车自然触发的七类精确请求，包含实际观察到的 APM `fetch` 与 `xhr` 两种发送类型；`xhs-note-open-experimental-v2` 只允许点击已观察的同源 `/explore/{24位十六进制标识}` 或 `/search_result/{同类标识}` 笔记链接，并允许八类精确请求，包括已实测的正常浏览历史上报；`xhs-readonly-ui-experimental-v1` 在实际非敏感、非表单根的读取/提取/等待/滚动期间，只允许 `collect xhr` 和 `apm_data fetch` 两类辅助流量，body 仍只适用原有的滚动/等待例外。第四类 `xhs-search-scroll-experimental-v1` 仅对官网精确 `/search_result` 或 `/search_result_ai`、已观察唯一普通根、显式 `scroll_scope:"viewport"` 且解析后非空文字 `until_target` 的定位动作额外允许既有精确 `search_notes xhr`，共三条规则；不含搜索历史、onebox、dqa、APM xhr 或任何用户互动写入。私有状态绑定签发时的完整页面地址与时间，页面/查询变化、早到、到期、非当前主框架或动作结束均不能使用。普通读取和滚动不继承该例外；历史版本证据按各自原规则清洗。
+
+legacy 集合链接必须经精确目标匹配和执行前再次核对，得到唯一实际对象，不能用集合本身授权多次点击。规则均固定方法、origin、pathname 和资源类型，不能相互借用；通用只读辅助策略不能放行检索、feed 或历史接口，搜索分页只适用上述独立动作范围，未知请求和其他点击继续受保护。
+
+策略不会主动请求接口，动作结束即撤销。请求摘要记录匹配版本和规则，后台兼容历史搜索 v1、笔记打开 v1 证据。它允许普通页面操作的有限辅助请求，不声称这些操作在服务端绝对没有状态变化。不能据放行或 URL 认定搜索/详情成功，须另查实际笔记卡、标题、来源和详情正文；规则放行本身不代表完整链路正确或正式可用；当前各候选的执行与质量状态见开发进度。

+观察的 `elements` 还提供有界的可读定位：实际可见的普通 id、语义容器/标题、纵向滚动容器，以及从当前 DOM 的 id 族或重复安全 class 核对得到的集合。`selector_basis/source_selectors` 记录定位来源，`read_hints` 最多给出 12 个真实后代的相对 CSS 和有限字段提示；`scroll_y` 说明当前容器高度、位置和是否可继续滚动。总候选不超过 120、离屏最多 30，这些提示不保证网站以后保持同一结构。调用方先核对实际页面，再为字段命名和配置有限提取；旧的独立单批输出分别保留来源，新批次模式只按核对过的业务标识聚合，不把多批数量相加当作唯一评论数。
+
+`open/status/ready` 返回 `login_detection`，只根据可见页面区分已登录、未登录、需要验证或不确定；不读取 Cookie、存储或表单值。已登录无需重新扫码，仍需明确确认当前账号；发现退出或验证会撤销当前可执行状态，恢复后再次确认。不确定不等于未登录，也不会撤销仍有效的人工确认。
+
+候选验证的 `mode` 为 `exploration` 或 `runtime`。后者必须有运行前基线 `baseline_note`，并配置 `observation_window_minutes`。质量观察的 `waiting / clear / alert / uncertain` 是维护者手工复查结果；`clear` 还要求试跑成功、配置窗口已到期且过程审核通过，若填写实际复查时间，该时间也须已到期。提醒晚到时继续追加到原验证记录，原记录和候选摘要不被改写。窗口是复查范围，不是平台安全阈值；维护验证状态不等于桌面交付或正式发布。
+
+能力详情提供“正式模式试跑”直达入口，复用配置弹窗并预选正式模式；原“配置测试”入口保留探索默认值。验证详情说明下一次复查时间和官方消息/搜索/详情/评论功能检查项；账号本人可将实际结果告知本地 Codex，由其代为追加记录。窗口到期不自动通过，也不把运行前“正常”代填为任务后的无异常结果。回放保留受限 `error_codes` 及原错误文字，缺字段、等待超时或登录失效不会转换为空态。
+
+新回放附 `step_timings` 与 `verify_timing`，阅读和验证页面可回看。前者按真实已执行步骤保存 `step_position/kind/status/duration_ms/phase_ms`，阶段限定为输入核验、当前检查、前置取证、目标解析、执行、等待就绪、请求核验、后置取证、失败取证及批次截图；阶段独占计时，未进入的阶段不补零。后者记录总耗时、入口耗时及预算关闭耗时，`close_ms:null` 表示未尝试关闭。失败只保留实际执行前缀，中断不能迟到改成成功；旧记录没有这些字段时显示未记录。耗时不含页面文字或业务参数，也不代表全部是平台响应时间。
+
+已观察定位的当前检查只查询该定位或批次滚动根，复用整页观察的元信息构造、定位语义及敏感判断；普通定位仍须保持原 canonical CSS，集合仍核对类型、数量与代表对象。最新观察、动态唯一匹配、固定实际对象、来源、只读请求和预算检查保留。每步后与每批仍做完整观察和真实截图，限定检查不代替这些证据；测试与真实候选追加验证分别记录。
+
+需求分析不调用浏览器，只使用当前维护者已有、来源核对通过且具正文的完整/部分阅读。模型输入最多 21 个来源、16,000 字，包含文字、临时来源引用、服务端固定的 `context_refs`、未解释媒体标记及必要商家条件，不发作者、真实对象 ID、链接、图片或凭据。`note.context_refs=[]`，每条 `comment_N.context_refs=["note"]`；笔记正文只提供一次，不复制到每条评论，也不接受调用方传入背景。后台逐项核对分类、覆盖、本源逐字依据和独立背景依据，媒体无文字不发模型、由程序标为信息不足；身份始终待核实。结果、固定错误、主/备槽位、实际已返回 Token 与未知费用追加保存到 `analysis_runs`，旧阅读不变。
+
+`analyses.create` 的 `data` 可传 `business_brief_id`，须为同维护者已确认版本；不传则继承阅读绑定的版本，旧阅读沿用原初筛条件。当前模型输入另含必要业务条件，保存独立的角色、表达、自身需求及相关性；服务端派生匹配、理由与展示建议，不执行关注、私信或评论。上下文摘要参与复用，旧结果不重写；地区未知不能当作全国或已匹配。
+
+新分析使用 `renovation-demand-v4 / demand-result-v3`，每项新增 `consultation:{value:"yes"|"no"|"unclear",evidence:[],context_evidence:[]}`。yes/no需1–3条本源逐字依据；yes须业务相关，表达含提问、求建议或自身需求；评论yes另须 `context_evidence:[{source_ref:"note",evidence:["笔记逐字依据"]}]`。最多一个背景来源，每条引用不超过1000字；禁止引其他评论、外部来源或把背景当本条自身事实，模型额外输出动作、匹配等未声明字段会拒绝。`lead_disposition` 和有限 `next_step:review_consultation` 由服务端派生；保留咨询待核不会把自身需求、身份、地区或 `match` 升为已确认。上述字段保存在现有JSON事实中，不改数据库schema或新增线索表；旧分析不补字段，复用须匹配新提示/结果版本。
+
+`reviews.create` 的旧五轴 `data` 为 `{source_ref,previous_review_id,decision,labels,evidence,note}`；新六轴另有 `context_evidence`。`previous_review_id` 首次为 null，修订须回传该来源最新核对编号；过期返回 `REVIEW_STALE`，先重新读取再由维护者决定，不能自动重发。`decision` 为 `confirmed/corrected/uncertain/unreviewable`；前两者传完整标签，后两者传 null 并说明原因，新合同另传空背景依据，旧合同省略背景字段。`demand-result-v2` 只接受原五轴 `labels:{role,demand,expressions,business_relevance,match}`，禁止加咨询/背景字段；`demand-result-v3` 要求六轴新增 `consultation:"yes"|"no"|"unclear"`，本源 `evidence` 与关联笔记 `context_evidence` 分开校验。评论yes必须有真实笔记背景依据，no须本源依据，unclear可为空。修正至少改变一轴，须说明和1–3条本源逐字依据；confirmed须与该版本原模型各轴相同。纯媒体不得标确定结论，地区不足不得标匹配，更早结果结构保持只读。
+
+旧分析核对保存 `analysis-review-v1`，新分析保存 `analysis-review-v2`，均绑定分析/来源摘要、原标签、维护者和前版引用，沿用schema 9的 `analysis_reviews` 追加保护；旧记录不迁移或补值。`reviews.summary` 按分析版本返回最新核对、分状态数量、五/六轴差异和已判定标注一致率；分母只含 confirmed/corrected，无样本为 null，不等于精确率或召回率。真实人工标注不能由合成验收或 Codex 自动生成代替。
+
+确认体所有字段必填：`platform:"xiaohongshu"`、`service:"装修服务"`、`target_customer:"有装修需求的业主"`、`search_terms`（1–3 项）、`region`（文字或 null）、`region_scope:"unspecified"|"specified"|"unrestricted"`、`exclude_service_promotions`（布尔）。指定地区须有文字，另两种须为 null；不限地区必须显式选择，确认不再调用模型。解析和确认以 schema 8 的 `business_briefs` 追加保存，维护者补充来源注明 `maintainer_edit`，不伪造原文依据。
+
+模型通过服务端 `ASSISTANT_MODEL_*` 配置；主/备用只切不同 Key，不升级型号，不重放浏览器。限定错误最多转一次备用，单请求最多 30 秒、整次最多 60 秒；格式/业务依据错误不切换来掩盖失败。相同阅读摘要、配置及提示/结果版本已完成时复用原分析；进行中返回 `ANALYSIS_BUSY`，失败或超时先查历史，再由维护者决定是否另发请求。Token 汇总不包含未返回的未知用量，不能当作实付费用或商家扣费。
+
+批次时间上限仍为 15 秒，包含读取、滚动和批次取证，并不晚于当前动作请求策略的到期时间；在上限内预留最多 2 秒关闭。截止会中断当前浏览器上下文、撤销策略和 ready，返回 `BATCH_BUDGET`，不续签窗口或自动重放。仅实际关闭事件确认才报告 `session_closed:true`，录制和验证都撤销后台就绪。总试跑预算先到时仍为 `VERIFY_BUDGET`。每批先暂存数据，实际完整观察与 PNG 完成、来源/根/登录/请求复查通过且未到期后才提交；截止时只可保留已提交批次的深复制前缀，`truncated:true / stop_reason:time_budget`，关联验证仍失败、业务阅读仍为部分完成。没有完成批次不返回评论，不能据此确认无评论；来源变化、冲突或不符合当前模式通信合同的请求，均不能借部分输出冒充成功。
+
+完整观察仅在单次同步 DOM 求值中缓存重复的节点几何、样式、敏感判断和文本遍历，不跨调用、页面或滚动保存缓存；原筛选、上限、全文/视口、敏感掩码及逐批真实截图保留。`test-observation-cache.mjs` 使用显式提供的修改前基线做隔离浏览器等价比较；`test-batch-deadline.mjs` 在本机夹具验证取消与部分结果。内部缩短预算只供模块测试，维护 API 和 JSONL 不开放预算覆盖。
+
+legacy 官网 `wait` 在进入自动化前预检现有只读策略；新 profile 在相同根/目标检查后独立建立原生通信动作窗口。未声明范围时，最新观察未包含目标集合、当前实际根为空或其他前置不满足，返回 `READONLY_WAIT_NOT_READY` 并保留失败证据，不进入无策略的自动化等待；敏感对象仍为 `SENSITIVE_OUTPUT`。策略窗口和规则均不扩展，不继承上一搜索步骤权限；非官网示例等待行为与原 body 例外保留。
+
+加载过渡可显式声明 `{"kind":"wait","selector":"#global a.title","wait_scope":"#global","state":"visible","min_count":1,"timeout_ms":10000}`。这里的 CSS 仅为格式示例，真实使用须先观察并学习当前页面。`wait_scope` 只允许可见集合等待，根须来自最新观察的唯一、可见、非敏感普通读取容器；body/html/form 等不适用。目标可以尚未出现，只在固定根内查询，范围外同名对象不计数；计数仅含可见、在视口且非忙碌对象。根/页面来源变化、敏感对象或超过100项停止；完整后置观察与截图后再次核对根及条件，冻结根的真实证据。旧步骤不自动获得新字段，阅读仍支持原七/八步结构。
+
+范围等待的 `timeout_ms` 覆盖轮询与根/集合/登录检查，最长15秒且不晚于当前策略到期，在内部预留最多2秒关闭。到期返回 `WAIT_TIMEOUT`、撤销 ready 和策略，实际关闭确认才回传 `session_closed:true`；不自动重开或重试。后置取证在撤销自动化和策略后执行，沿用原截图限制与整轮总预算；总截止先到为 `VERIFY_BUDGET`。`test-scoped-wait.mjs` 只用本机隔离浏览器与官网元数据纯用例，不能代替真实平台学习与回放；加载状态及实际结果见进度。
+
+`pnpm test:control` 只验证隔离的本机传输夹具，`pnpm test:session` 验证合成 DOM 登录状态，`pnpm test:platform-policy` 验证实验策略的纯函数边界。真实浏览器工具与完整 API/UI 验证分别由 `node tools/learning/test-browser-worker.mjs` 和 `pnpm test:learning` 覆盖；均使用本机合成页面，不访问真实账号。
+
+## 浏览器工作进程协议与生命周期
+
+维护 API 以标准输入输出的逐行 JSON 调用 `browser-worker.mjs`，不把工作进程直接开放给网页。输入为 `{ "id":"request-id", "method":"capture", "params":{"task_id":"task-id"} }`，输出为同一 `id` 的 `result` 或含 `message/code` 的 `error`。标准输出只用于协议，调用按顺序执行；工作进程不调用模型。
+
+- `open` 接收 `task_id/account_key/entry_url`，打开固定资料目录，等待人工登录；`ready` 记录 `identity_label`，之后必须显式 `capture` 才开始录制。
+- `capture` 返回当前文本、视口文本、定位候选、视口截图和证据路径，优先当前视口，限制离屏候选数量并排除隐藏文字；`action` 执行上述受限动作并保留成功或失败前后证据。
+- `verify` 从入口重放冻结步骤，以参数替换输入和目标，按预期文本或明确空态核对实际读取结果，报告真实系统和浏览器版本。
+- `status` 查询 `awaiting_user/observing/closed`；`close` 关闭上下文并释放账号占用，保留资料目录。
+
+关闭标准输入或输出管道断开会立即关闭进程持有的浏览器上下文，执行中的试跑自然中断。关闭入口等待同一个清理过程，不重放排队动作；调用方须等待实际退出，再重开同一资料目录。相同账号资料同一时刻只能由一个任务持有。
+
+`ASSISTANT_LEARNING_HOME` 默认为 `.runtime/learning`，浏览器资料按 origin 和后台限定的账号引用散列分目录。`ASSISTANT_BROWSER_CHANNEL` 默认 `chromium`，可指定已安装的 `msedge`；浏览器缺失时返回明确错误，不自动安装。`ASSISTANT_BROWSER_HEADLESS=1` 用于隔离测试，维护者登录正常使用可见浏览器。
+
+首期限定入口同一 origin，不支持跨站 SSO。人工确认前不采集页面；证据过滤敏感表单/输入值，截图遮盖输入区。持久化 Cookie 与人工声明均不等于自动身份核验。legacy 自动动作期间默认拦截非 GET/HEAD/OPTIONS 请求，仅允许上述四类实验策略的精确匹配例外；显式新 profile 按本页固定动作/原生通信合同执行，不将未知第一方 POST 一概认定为业务写入。其他平台取数适配须另行观察确认。
+
+浏览器回归使用 `.tmp/worker-regression-*` 的隔离页面和资料目录，覆盖会话确认、互斥、敏感字段、受限动作、变参读取、错误断言、Cookie 重开及执行中 EOF 清理。成功后默认清理；`node tools/learning/test-browser-worker.mjs --keep-artifacts` 可保留报告与截图。关闭后再次试跑仍须重新打开会话并人工确认。
+
+新模型合同诊断只对实际输出失败追加 `output_diagnostics:{check}`，仅接受16个固定无文本枚举；成功与旧记录不补造。它不包含原始模型输出、来源编号、URL或供应商错误，不改变允许范围或触发自动重试。当前有限真实验证见进度：一条首轮合同失败保留，后续独立新分析通过，不能倒推首次具体原因或整体稳定性。
+
+
+## 通用链路复用验证
+
+后台入口为“学习 → 链路复用”，地址 /#/routes。先选同任务/站点/执行配置的搜索和详情候选，填新关键词，再“召回并锁定版本”→“执行变参验证”。召回只固定ID/摘要；执行复用当前已确认的会话，不自动开启浏览器，不调用业务模型。当前详情候选仍含重搜前缀，组合会搜索两次。
+
+routes.resolve 的 data 为 {platform,task_type:"search_note_comments",search_candidate_id?,detail_candidate_id?}。routes.verify 再传两个固定引用、search_digest/detail_digest和keyword，可选note_id只从本次实际结果选择，不能传外部标题或动作。未指定ID且有多对时409。组合kind=route在原验证历史保存；默认呈现usable_outputs，原始actual_outputs仅作失败取证。route不晋级正式质量或发布。
+
+维护者已明确持续授权固定学习账号；本地Codex后续检测同资料目录仍已登录即可沿用授权完成ready，不再重复询问账号。登录失效、需验证或会话异常时暂停并提示；不把持久Cookie单独当作登录有效或自动身份核验。
+
+## 功能入口与页面层级盘点
+
+后台“学习 → 平台路径”（`/#/platform-paths`）按五组展示首批33个功能模板。它不是平台功能总数；每项以功能路径盘点任务中的官方页面、当前可见非敏感元素、分类标记及已登记截图引用共同核对，只有标记或文字不算完成。页面不加载私人截图或展示昵称/原文，读取账本不会操作平台。已有搜索/正文/首层评论的组合验证独立展示，不将观察入口晋级成已固化能力。
+
+盘点任务显式选择 `playwright-xhs-navigation-ui-v1`，合同为 `engine:playwright / action_policy:xhs-observed-navigation-readonly-v1 / network_policy:xhs-page-navigation-v1`。支持已观察且实际唯一可用的发现/搜索/标准笔记/公开主页/通知同站锚点；点击前固定实际href，动作后核对目标。笔记仅允许同官方站点、相同24位编号的标准笔记路径别名与跟踪参数变化。公开主页只允许实际省略原链接中各最多一个channel_type/parent_page_channel_type，必须确实省略至少一项；其余有序query、xsec、路径/对象/hash保持一致，无省略仍完整地址相同，其他目标继续按完整地址核对。页面新开窗口必须属于本步明确点击的opener与目标，实际主框架沿用原动作策略及截止时间，不续签；旧v1与legacy不获得这些权限。
+
+发布者和评论者的主页入口分开记录。按当前页面→可见入口→下级控件→关闭/返回→参数化候选→独立验证推进，动态对象取样。`更多`、非语义标签和回复展开等控件尚待固定识别及真实状态断言，不将未捕获算作不存在；消息窗口、关注/取关、评论/回复发布和私信发送尚未学会，本轮不实际发送或改变关系。
+
+工程检查分别使用 `pnpm test:navigation-profile` 和 `pnpm test:platform-paths-ui`；本机合成导航、纯合同判断、真实平台观察及冻结回放分别报告，不互相替代。实际样本与缺口见开发进度。
