+## 目标
+
+按 ../spec.md 实施 A 和配套 B。用户已授权本地修改与验证。
+
+## 进度
+
+- 2026-09-08 已完成本地实施与验证。`Status` 为分诊标签，实施进度以本节为准。
+- 28 个工具按 Alpha、同步任务、数据目录、研究构建、回测五组声明；通用装配和运行时不再维护独立确认名单或按工具名执行的分支。
+- 卡片外壳消费服务端 presentation，领域卡片负责具体展示；刷新目标和导航动作显式声明，未知展示形态保留原始记录并禁用确认。
+- 模型摘要与完整持久化结果分离；准备产物失败回滚、旧确认恢复、能力移除后的确认拒绝均有回归覆盖。
+- 独立核验发现提交后通知异常会阻止聊天收尾，已通过故障注入复现并修复：保留已提交操作、持久化 `_warning`，继续收尾；重复确认不会再次执行或通知。
+- 模块接入位置、效果类型、展示/刷新/导航标准与测试要求记录在 ../spec.md。
+
+## 验证
+
+- 后端 `uv run pytest -q`：最终全量 **148 passed in 37.22s**。
+- 后端 `uv run ruff check app tests`：通过；本次 Python 文件 Ruff 格式检查通过。
+- 前端 `pnpm build`：类型检查和生产构建通过；保留依赖 lottie-web 已有的 eval 构建提示。
+- 前端 `pnpm test`：最终全量 **16 passed (1.9m)**。覆盖未知 renderer（包括原型属性名称）、旧卡片、确认、草稿保留、窄屏，以及固定输入→聊天确认→回测→原会话→固定输入的来源回链。
+- 本次前端文件 Prettier 检查和 `git diff --check`：通过。
+- 与基线直接比较工具定义：28 个工具名称、JSON schema、描述无变化；确认要求集合一致。平台研究范围仍从当前账号的平台选项读取。
+- 首轮浏览器验证中，新增导航测试因会话标题与消息重名导致定位歧义，已限定到用户消息；既有 workspace 测试发生一次抽屉遮罩时序失败，未修改其业务代码，专项与最终全量重跑均通过。
+
+以上只使用临时数据库、合成模型和模拟 WorldQuant HTTP；未验证真实模型研究质量或真实平台运行。未增加依赖或数据库迁移，未部署或提交 Git。跨轮研究上下文（C）按本次范围留待后续。

+# AI 能力接入与工作区联动
+
+Status: ready-for-agent
+
+用户于 2026-09-08 确认按架构评审建议实施。当前基线为 `3d26827`，保留平台研究范围发现修复。
+
+## 范围与决定
+
+- 实施 A：按领域集中工具参数、描述、查询/准备产物/确认执行策略、处理函数、提交后通知及工作区展示信息。运行时统一管理登录、预算、确认、审计与事务。
+- 配套实施 B：统一卡片外壳、按明确 renderer 分派，移除前端工具标题和写入名单；服务端返回刷新目标，前端按目标刷新并保持草稿。导航动作显式映射，未知能力显示保守降级。
+- 模型使用有界摘要，持久化卡片保留完整的业务返回；摘要截断显式标记。PnL 仍只返回摘要，完整序列按业务引用读取。
+- 保留现有工具名称、参数与确认记录；旧持久化记录由当前能力定义补齐展示信息。已移除能力的待确认操作拒绝执行。
+- 查询不得产生业务写入；准备能力仅保存约定的本地产物；需要确认的操作保留固定目标、版本检查与幂等。所有工具业务操作使用保存点，失败回滚业务修改并保存失败审计。通知只在提交后进行。
+- 提交后通知失败时保留已完成操作，持久化并展示 `_warning`，继续结束聊天；不重复提交业务操作。通知只负责唤醒或中断既有 runner，不能承担业务落库。
+- 不改变单管理员、单进程、回测确认和生成中断恢复语义；不实施 C、不增加持久研究焦点、自动续跑、框架、依赖或迁移。
+
+## 接入路径
+
+1. 明确领域归属、输入/输出、范围/版本/单位/null、失败和副作用；业务 implementation 复用既有 module。
+2. 在领域的 `ai_tools.py`（Alpha/任务暂位于 `ai/`）声明完整 Capability；新领域在 `ai/tools.py` 装配一次。
+3. 提供查询或 prepare handler；确认操作同时提供 preview、execute 和必要的 after_commit。身份和事务由 AIRuntime 管理，不从 handler 提交事务。
+4. 固定研究输入与来源，生产候选复用 ResearchBuilder / Backtests；长任务只返回既有任务或运行引用。
+5. 复用已有 renderer；新展示形态只在前端工具卡装配处注册一次，展示与业务逻辑留在领域。声明需要刷新的资源，补齐明确的 UIAction 目标。
+6. 测试跨业务 interface 的可观察行为，覆盖失败原子性、确认、恢复、结果摘要、卡片、来源回链与草稿保留。
+
+## 实际入口与接入标准
+
+| 需要增加的内容 | 修改位置 | 完成标准 |
+| --- | --- | --- |
+| 既有领域的新能力 | `backend/app/<domain>/ai_tools.py`；Alpha/同步任务分别为 `ai/alpha_tools.py`、`ai/job_tools.py` | 名称唯一，声明 schema、description、label、renderer、effect、处理函数和 refresh；修改领域说明中的使用约束 |
+| 新领域 | 领域自己的业务 module 与 `ai_tools.py`，在 `backend/app/ai/tools.py` 的 `DOMAINS` 装配 | 通用 runtime 无工具名分支；业务权限与校验复用既有 interface |
+| 新卡片形态 | 领域展示文件及 `frontend/src/ai/ToolCard.tsx` 的 renderers | 通用确认、错误、通知警告留在外壳；未知 renderer 仍可查看记录，但不能确认 |
+| 新页面或导航动作 | `frontend/src/ai/types.ts`、`frontend/src/ai/workspace.ts` 及目标页面 | 显式资源引用、页面目标及聊天开关策略；穷尽类型检查通过，不能默认跳到 Alpha |
+| 新刷新资源 | 后端 `Resource`、前端 `Resource` 及 `App.tsx` 的刷新处理 | 声明值可校验，已完成工具才触发刷新，重复快照不重复刷新；不清空人工草稿 |
+
+`query` 只读取业务事实，不能声明刷新或提交后通知；`prepare` 只能保存本地输入/预览，不能开始后台执行；`confirm` 必须同时提供 preview 与 execute，执行时重新检查固定目标和版本。效果类型约束在能力装配时检查，handler 的实际副作用通过业务 interface 与行为测试保证，不把声明本身视为隔离机制。
+
+模型拿到 `model_result` 摘要，审计与卡片拿到完整业务返回。长结果应提供分页与稳定引用；领域约定的摘要（如 PnL）仍保持原语义。截断会附带 `_meta.truncated`，不能将摘要解释为全部数据。旧卡片从当前能力补齐 presentation，能力移除后的确认请求会产生失败审计。
+
+新增能力至少提供一个通过实际 runtime 的成功路径，并覆盖与副作用相关的失败/确认/重复请求路径。涉及研究来源或新导航时，再补浏览器中的来源回链；复用既有卡片形态时无需另建一套展示测试。不要复制通用执行器的确认、事务和模型预算逻辑。
+
+## 验证
+
+后端 Ruff 和全量 pytest；前端类型检查/构建及隔离 Playwright。新增接入完整性、prepare 失败原子性、历史确认兼容、摘要不改变持久化产物与前端降级/导航回归。只使用合成模型、模拟 HTTP 与临时数据库。不部署、不提交、不调用真实平台或收费模型。

+- 模板稳定 ID、不可变版本、编辑/采样/展开、旧格式导入预览和同名冲突保护。随机采样直接访问组合空间，不先穷举。
+- 结构与字段变体、市场与设置变体；保存种子、输入、改动、模板版本及模型生成依据。每个候选保留实际输入引用，回测结果通过实验 ID 与 client_item_id 追溯。
+- 基线与候选比较：表达式、设置、指标快照、共同日期窗口 PnL；缺失指标不当作零。
+- 页面和 AI 共用研究服务；原 Chatbox 绑定使用共用表达式展开及语法/类型校验。所有手工回测继续先生成固定预览，再由用户确认。
+
+## 验收步骤与结果
+
+| 验收 | 步骤 | 结果 |
+|---|---|---|
+| 后端回归 | `backend/.venv/bin/pytest -q --tb=short` | 176 项通过；包含新增研究及原账户、目录、AI、回测、Alpha 测试 |
+| 追加类型边界 | 直接 VECTOR、非聚合算子使用 VECTOR、局部 VECTOR 后显式聚合；重跑研究相关测试 | 44 项研究相关测试通过；修复仅收紧本地类型校验 |
+| 组合空间 | 重复占位符；100^20 组合取 50 个随机候选；相同随机种子重复生成 | 数量受限、结果可复现；全组合超限返回错误 |
+| 版本与导入 | 保存 v1、更新 v2、重新读取 v1；并发旧版本写入；旧占位符转换及同名导入 | 历史不变，冲突返回 409，同名不覆盖 |
+| 生成与来源 | 固定输入→模板候选→原预览→合成模拟→Alpha 来源；父实验及目标市场输入 | 来源保留，可由实验 ID + 候选 ID 找到输入版本与种子 |
+| 字段和范围 | 未知字段、错误字段类型、跨市场独立输入、局部变量、字段级证据与目录矛盾 | 无法核实的候选保持待核实；不进入选定候选回测预览 |
+| 模型接口 | PydanticAI FunctionModel 返回结构化模板 | 单次请求；模型/配置版本/用量/输入上下文保存在模板版本，未调用真实模型 |
+| 比较 | 两条 Alpha 使用不同设置、缺失 Sharpe、部分重叠 PnL 日期 | 保留 null；仅共同日期且窗口起点归零；不同设置明确标识 |
+| 前端构建 | `pnpm --dir frontend build`、TypeScript 检查 | 通过；依赖 lottie-web 的既有 eval 提示不阻塞构建 |
+| 浏览器回归 | 项目 17 项 Playwright 用例，全新临时 SQLite、合成平台、独立 localhost 端口 | 17 项通过，覆盖账户、菜单、配置、AI、目录、回测、Alpha、多尺寸与恢复 |
+| 页面闭环 | 浏览器固定 TEST_FIN 输入，创建“阶段一浏览器验收模板”v1，生成两个候选，确认回测，查看结果后返回原实验 | 2/2 结果已保存，来源返回原实验及关联回测；创建候选时运行数量仍为 0 |
+| 算子备注 | 浏览器收藏 rank、保存备注、同步算子、重新选择 rank | 平台定义刷新后，本地备注和收藏仍在 |
+| PostgreSQL | 专用 PostgreSQL 17 容器中执行 `backend/tests/research_postgres.py`：0005→0006、Alembic schema check、旧研究备注、并发版本写入、重复回测启动 | 通过；旧备注/版本保留，两个并发启动返回同一运行 |
+| 备份恢复 | 专用库 pg_dump，恢复至新库；核对模板版本、实验、回测数量和旧备注 | 通过；未操作个人工作数据库 |
+
+## 交付边界与未完成验证
+
+本阶段没有上线部署、正式提交 Alpha、回写平台属性或调用真实模型。新增生成和模拟限定 REGULAR / FASTEXPR / EQUITY；其他已有 Alpha 展示不受影响。
+
+真实 WorldQuant 联调脚本已准备：仅向官方 API 认证，读取算子、OPTIONS 设置及字段可用性，不保存凭据。沙箱内请求返回 network_error；提权执行被自动审批两次拒绝，理由为审批器未认可任务目标记录中的外部账户授权。已在当前对话发出明确授权确认问题，等待回复。本报告不把合成协议测试视为真实平台联调通过。
+
+可用性协议无法识别时明确标为待核实。完整的目标范围目录及独立固定输入可以提供字段存在证据；若存在额外字段级证据，则要求同时满足。原始时间序列离线特征计算、官方检查/提交、旧运行搬迁均不在本阶段范围。

+# 第二阶段验收：特征与成果管理
+
+日期：2026-09-08。范围：特征方案、保存视图、变体关系、版本化评估。未调用真实模型或 WorldQuant；平台调用使用隔离合成响应。
+
+## 交付行为
+
+- 特征方案保存固定输入快照、经济假设、处理步骤及输出模板，支持历史版本、AI 结构化生成和转换模板；转换保存完整方案版本，并在模板工坊恢复输入和假设。
+- Alpha 保存视图持久化筛选、排序和显示列，支持搜索恢复、新建及乐观版本更新。

+| PostgreSQL 备份恢复 | 通过；独立测试库 pg_dump/pg_restore 后研究版本、评估、关系数量和旧备注一致。脚本 `backend/tests/research_outcomes_postgres.py`，日志 `/tmp/wq-stage-two-postgres.log` |
+
+浏览器首轮发现的是验收定位与合成测试参数问题：固定输入使用既有的 all/excluded_ids 协议；保留草稿的隐藏页不能用全局标签定位；Semi 弹窗确认按钮的无障碍名称为 confirm。修正后新增闭环通过。全量回归另发现共享合成数据使 Alpha 不在第一页，以及旧数据数量提前满足断言造成任务浮层晚打开；改为筛选目标 Alpha、等待对应任务完成及浮层出现，相关场景复验通过。
+
+## 边界
+
+关系图响应限制 100 个实验、8 层；截断时明确提示并提供边界继续展开。每条原始回测来源仍可分页完整读取。评估模型解释一次最多使用 20 条规则记录，保存选取范围，不改变完整规则报告。特征步骤不执行原始时间序列离线计算。
+

+# WorldQuant 真实联调验收
+
+日期：2026-09-08。用户在当前对话明确授权使用 account.json 连接真实 WorldQuant，并再次确认可以真实回测。本次使用项目现有业务接口与回测调度器，执行真实认证、目录查询、6 条模拟、结果收集和 PnL 查询；未正式提交 Alpha、触发官方检查或修改平台属性。
+
+## 真实执行结果
+
+所有模拟限定 REGULAR / FASTEXPR / EQUITY、USA、Delay 1，单条顺序执行。第 3 条使用 TOP1000，其余使用 TOP3000；共 6 次模拟、5 个不同 Alpha ID。
+
+| 阶段及场景 | Alpha ID | 结果 |
+|---|---|---|
+| 一：模板展开及来源 | KPOE0M9g | 完成，保存候选预览、回测结果与模板版本 |
+| 一：结构变体 | wpYExOel | 完成，保留种子、表达式改动与研究来源 |
+| 一：设置变体 | gJQ9E3km | 完成，保持表达式，独立固定 TOP1000 输入并保留原输入 |
+| 二：特征方案转模板 | Vk63gxAJ | 完成，保存特征版本、候选、结果与规则报告 |
+| 三：固定研究流水线 | KPOE0M9g | 一轮 8 步完成，1 条真实模拟；平台返回与首条相同的 Alpha，两次研究来源都保留 |
+| 四：QuantFlow 原生节点 | O0rxaPOJ | 6 节点完成，1 条真实模拟、0 次模型调用 |
+
+采用价格变化及截面排序表达式，仅用于接口与执行链验收。特征 Alpha 的版本化规则评估为 `block`；模拟成功不代表质量规则通过或可正式提交。
+
+固定流水线的模型步骤使用本地确定性测试输出，记账 1 次；没有调用真实模型供应商。真实模型生成质量不在这次 WorldQuant 联调结论中。
+
+## 元数据、成果与追溯
+
+- 官方认证成功；读取 101 个算子、46 组合法模拟设置。
+- USA/TOP3000/D1 和 USA/TOP1000/D1 分别完成 pv1 目录同步及固定输入，各含 24 个字段；close 的字段详情返回 48 条可用范围记录。
+- 查询基线 KPOE0M9g 与结构变体 wpYExOel 的真实 PnL，取得 2,494 个共同日期，窗口为 2014-01-02 至 2023-12-29；设置一致，共同窗口比较成功。
+- 关系查询返回 6 个相关实验及 4 条父来源边，包括准备阶段尚未回测的实验。基线 Alpha 同时保留模板与流水线两条已回测来源。
+- 重新同步 Vk63gxAJ 后，评估报告 541982d6-5f41-4d40-b42e-da3cd631a77c 的内容完全不变。
+- PnL 初次查询遇到平台异步准备；首次限制为单次读取的验收进程返回 pending。按项目正常的 4 次读取重试配置等待后，两份 PnL 均取得。该过程没有再次发送模拟。
+
+## 实际发现及修复
+
+1. 字段可用性协议：真实 `/data-fields/{id}` 使用 `data` 数组，行内不带 instrumentType。新增该形式的适配，instrument 仅来自明确的请求上下文；市场、股票池、Delay 仍必须由响应逐项提供。缺失或异常项目维持待核实；返回字段 ID 不符时不覆盖旧快照。
+2. Alpha 设置协议：真实结果包含可执行的 `maxPosition` 和历史窗口 `startDate/endDate`。OPTIONS 明确 maxPosition 为可选 ON/OFF 参数，而 startDate/endDate 不在 POST settings 中。新增 maxPosition，种子转换只排除这两个历史窗口字段，原始快照完整保留；未知执行参数仍严格拒绝。旧研究授权按相同默认值比较，避免新默认字段导致恢复时误判越权。
+
+第二项问题在设置变体准备阶段被发现，发生在第 3 次模拟发送之前。修复后复用前两条已完成结果，继续完成剩余 4 条；没有重跑已完成模拟。
+
+## 验证与记录
+
+- 后端最终全量：224 passed，`/tmp/wq-live-full-regression.log`。
+- 浏览器：4 passed，覆盖普通回测、AI 固定确认、流水线和 QuantFlow，`/tmp/wq-live-browser-regression.log`。浏览器回归使用合成平台；上述 6 条真实模拟通过同一业务 API 和执行器执行。
+- Ruff、TypeScript 和 diff whitespace 检查通过。
+- 本次没有数据库 schema 变化；历史授权兼容已加入运行回归。
+- 真实运行与模拟引用、实验、模板/特征版本和评估保存在隔离数据库 `/tmp/wq-research-live-20260908/research.sqlite`。未覆盖业务数据库或原有前端布局改动。
+- 可核对的脱敏证据见 [worldquant-live.json](worldquant-live.json)。无账户密码、会话令牌或模型密钥。
+- 可复用联调入口：`backend/tests/research_live_acceptance.py`，需显式 `--execute`；HTTP 钩子限制总模拟数为 6 并拒绝其他平台写入。`--inspect-existing` 只允许认证与读取；`--resume` 只在先前模拟均完整完成并记录时继续，不会对未知提交重发。
+
+本次真实覆盖为一个市场、两个股票池和一个字段。其他市场组合及算子执行能力未逐一真实模拟；目录可用性与本地校验不能替代平台实际回测。

+# 研究功能迁移
+
+Status: ready-for-agent
+
+用户于 2026-09-08 明确授权实现对话中的四阶段迁移方案。范围为模板与变体闭环、特征及成果管理、预算内自动研究、原生 QuantFlow。保留单账户、单进程、现有平台快照与回测契约。追加要求：逐阶段完成、每阶段提交代码并提供验收报告；允许读取 account.json 进行真实 WorldQuant 联调与模拟回测。不得输出凭据。不部署；不进行正式 Alpha 提交或平台属性回写。
+
+## 产品与接口
+
+侧栏按数据与素材（数据目录、算子库、模板工坊）、研究实验（特征工程、Alpha 变体、回测研究）、研究编排（研究流水线、QuantFlow）、研究成果（Alpha 管理）分组。个人信息走用户菜单。新增功能有完整业务后才公开入口。
+
+统一表达式解析、类型化变量、有限组合与可复现采样；模板稳定 ID、不可变版本和导入差异预览；变体记录种子、改动与多输入快照；评估保留规则、证据、模型建议及缺失项；研究产物以数据库引用传递。原生流程共用业务节点与现有回测调度，固定配方和画布共用运行实现。
+
+新增 `/api/v1/research` 与 catalog 元数据接口；保留旧 Chatbox 与回测接口。研究授权由服务端保存并核验，含有限轮数、模拟条目、模型调用预算及固定范围/方法/版本。每轮保存不可变回测预览。停止不承诺远端取消；未知提交不重提。新研究候选不直接创建平台 Alpha。
+
+## 界面约定
+
+scope_sketch: 紧凑研究页面，素材编辑、候选预览、结果和运行控制；空状态指向真实输入准备。
+lark_style_recipe: 沿用现有白色工作区、浅色侧栏、蓝色主操作及 4px 基准，复用 Semi 控件。
+ud_control_coverage: Button、Input、Select、Tabs、Table、Modal、SideSheet、Tag、Banner。
+right_rail_policy: 沿用现有 AI 与业务面板互斥规则，跨页保留草稿。
+icon_plan: 保留现有侧栏图标系统；新增页面以文字与原生控件为主，不新增装饰图标。
+media_decision: 不需要图片；QuantFlow 以可交互节点和连线表达流程。
+
+## 验证
+
+表达式边界、输入归属及跨市场可用性、不可变版本、导入冲突、基线及来源、规则不被模型覆盖；固定回测确认、预算扣减、重复启动、暂停恢复、未知提交、流程连接与事件幂等。隔离 HTTP/数据库测试、前端构建与浏览器闭环、PostgreSQL 迁移和备份恢复。真实上游协议另行联调。
