+description: 当任务涉及 frontend 导入路径调整时使用，统一使用 @ 别名并禁止 ../ 上跳相对导入
+---
+# K12 前端导入别名规范技能
+## 何时使用
+- 修改 `frontend/src` 下任意 `ts/tsx/js` 文件
+- 新增组件、页面、路由、API、store、utils 模块
+- 代码评审指出存在 `../`、`../../` 上跳导入
+## 规范规则
+- 跨目录导入统一使用 `@/` 别名路径（如 `@/api`、`@/components`）。
+- 禁止使用 `../`、`../../` 等上跳相对导入。
+- 禁止使用以 `/` 开头的模块导入路径（如 `from "/utils/http"`）。
+- 同目录导入允许使用 `./`（如 `./index.scss`、`./types`）。
+## 执行步骤
+1. 搜索并定位 `frontend/src` 内所有 `../` 与 `/` 绝对导入。
+2. 将跨目录导入替换为 `@/` 别名。
+3. 运行前端构建验证（`pnpm --dir frontend build`）。
+## 约束
+- 不改变业务逻辑，仅在导入路径层面做规范化修改（除非用户另有要求）。
+- 保持 `tsconfig.json` 与 `vite.config.ts` 的别名配置一致。

+# K12Study Agent 工程规范
+
+本文件是所有自动化 agent（Claude Code / Cursor / Copilot 等）在本仓库工作时必须遵守的项目级规范。
+细则源文件位于 `.agents/skills/*/SKILL.md`，本文件是汇总入口，改动时两处保持一致。
+
+---
+
+## 1. 统一响应体契约（API Response）
+
+来源：`.agents/skills/k12-api-response-standard/SKILL.md`
+
+### 适用场景
+- 新增或改造后端 API
+- 改动前端 / 小程序请求层
+- 修复“后端已报错但前端当成功处理”的联调问题
+
+### 契约
+响应体结构固定为 `code / message / data / traceId` 四字段。
+- 成功：`code === 0`
+- 业务失败：`code !== 0`，前端必须抛错并使用 `message` 透出
+- `traceId` 必须保留用于链路追踪
+
+### 强制项
+1. 后端 Controller 与全局异常处理统一返回 `ApiResponse`（位于 `common-api`）
+2. 前端 `frontend/src/utils/http.ts`、小程序 `app/src/utils/request.js` 必须同时校验 HTTP 状态码与业务 `code`
+3. 新接口落地时同步检查类型声明与调用方解包方式，避免重复定义结构
+4. 同步更新 `docs/architecture/api-design.md` 中响应体约定
+
+### 禁止项
+- 禁止字段重命名（如 `message` → `msg`）
+- 禁止去掉 `traceId`
+
+---
+
+## 2. RESTful 接口风格
+
+来源：`.agents/skills/k12-restful-api-style/SKILL.md`
+
+### 适用场景
+- 新增 API 设计
+- 旧接口路径改造（如 `current-user`、`*/tree`）
+- 同步网关白名单与客户端调用路径
+
+### 设计规则
+- 路径优先使用资源名（名词），不是动作名
+- 集合资源使用复数：`/users`、`/departments`、`/classes`
+- “当前用户”使用语义路径：`/users/current`
+- 树形结构通过资源路径表达：`/areas`、`/tenants`、`/departments`
+- 统一入口前缀：`/api/*`，不得更改
+
+### 强制项
+1. Controller 使用 RESTful 主路径
+2. 改路径必须同步更新：前端 API、小程序 API、网关白名单、`docs/architecture/api-design.md`、`docs/architecture/logical-view.md`
+3. Feign 契约（`apis/api-*/remote/*RemoteApi.java`）与 Controller 路径必须一致；启动时 `FeignContractValidator` 会校验
+
+### 禁止项
+- **旧接口不兼容，禁止保留/恢复兼容别名**
+- 禁止动词化路径（如 `/getUser`、`/doLogin`）
+
+---
+
+## 3. 注释头规范
+
+来源：`.agents/skills/k12-comment-header-standard/SKILL.md`
+
+### 适用场景
+- 任务涉及 `global.code-snippets`、`.fileheader/fileheader.config.yaml`
+- 用户要求统一文件头 / 函数注释规范
+- `@author` 对齐 git `user.name`
+
+### 强制项
+1. 以 `git config user.name` 为 `@author` 基线（当前：**wangys**）
+2. 更新 `global.code-snippets` 中 `FileHeader` 与 `Method` 的 author 默认值
+3. 使用 `turbo-file-header` 的项目须检查 `.fileheader/fileheader.config.yaml` 的 `@author`
+4. 修改后验证 JSON / YAML 可解析
+5. 保留字段顺序：`description / filename / author / copyright / since`
+
+### 禁止项
+- 不在此规范下修改业务逻辑代码
+
+---
+
+## 4. 前端导入别名规范
+
+来源：`.agents/skills/k12-frontend-import-alias/SKILL.md`
+
+### 适用场景
+- 修改 `frontend/src` 下任意 `ts/tsx/js` 文件
+- 新增组件、页面、路由、API、store、utils 模块
+- 代码评审指出存在 `../`、`../../` 上跳导入
+
+### 强制项
+1. 跨目录导入统一使用 `@/` 别名路径（例如 `@/api`、`@/pages`、`@/utils`）。
+2. 禁止使用 `../`、`../../` 等上跳相对导入。
+3. 禁止使用以 `/` 开头的模块导入路径（如 `from "/utils/http"`）。
+4. 同目录导入允许使用 `./`（例如 `./index.scss`）。
+5. 改动后执行 `pnpm --dir frontend build` 验证。
+
+### 禁止项
+- 禁止新增任何 `../`、`../../` 或以 `/` 开头的导入写法。
+
+---
+
+## 5. Feign 契约与微服务边界（补充）
+
+> 非 skills 原有条款，但属于本仓库架构约束，agent 工作时必须遵守。
+
+- `apis/api-*` 模块只放 DTO + `@FeignClient` 接口 + 路径常量 + `FallbackFactory`，**不得**依赖 service / jdbc / redis
+- 新业务模块同时做 Provider + Consumer 时引 `common-feign`，自动启用 `@EnableFeignClients(basePackages="com.k12study.api")` + OkHttp + Authorization 透传 + 启动契约自检
+- 微服务模式通过 Nacos（`spring-cloud-starter-alibaba-nacos-discovery`）寻址，单体 / 本地联调通过 `k12study.remote.<module>.url` 走直连 URL 兜底
+- 熔断降级统一返回 `ApiResponse.failure(503, reason)`，前端按标准响应体处理
+
+---
+
+## 6. Agent 协作约定
+
+- 任务拆解与进度跟踪优先使用 `TaskCreate / TaskUpdate`，而不是把进度写进 memory
+- 任何对本文件、`.agents/skills/*`、`docs/architecture/*` 的改动都必须在同一次提交中同步
+- 本文件若与 `.agents/skills/*/SKILL.md` 冲突，以 SKILL.md 为准（SKILL.md 是细则源头）

+# 问题陈述
+基于现有 `auth` 与 `upms` 模块完成前后端可联调实现（含 Web 管理端与小程序最小可用链路），从“占位/硬编码”升级为“数据库驱动 + 令牌会话治理 + 端侧鉴权一致”。
+## 当前状态（已确认）
+* `auth` 已有登录/刷新/当前用户接口，但服务实现为硬编码用户，未校验真实凭据，refresh 逻辑未做轮换与持久化（`backend/auth/src/main/java/com/k12study/auth/controller/AuthController.java (18-47)`, `backend/auth/src/main/java/com/k12study/auth/service/AuthService.java (18-74)`）。
+* `upms` 已有 routes/currentUser/areas/tenants/departments 接口，但全部为静态返回；且模块配置排除了数据源与 MyBatis 自动装配（`backend/upms/src/main/java/com/k12study/upms/service/impl/UpmsQueryServiceImpl.java (17-132)`, `backend/upms/src/main/resources/application.yml (1-18)`）。
+* 数据库脚本已提供认证与权限组织核心表（含 `auth.tb_auth_refresh_token`、`auth.tb_auth_login_audit`、`upms.tb_sys_*`、班级/文件/站内信相关表），但代码未接入（`init/pg/auth/10_create_auth_tables.sql (1-64)`, `init/pg/upms/10_create_upms_tables.sql (1-437)`）。
+* Web 端当前仅保存 accessToken，未使用 refreshToken，且路由初始化失败时会回退默认路由，缺少严格登录守卫（`frontend/src/pages/LoginPage.tsx (17-21)`, `frontend/src/utils/storage.ts (1-12)`, `frontend/src/router/AppRouter.tsx (56-83)`）。
+* 小程序端仅有 API/request 封装，无登录页、无 token 持久化与鉴权头注入（`app/src/api/auth.js (1-13)`, `app/src/utils/request.js (1-53)`）。
+* 目标能力与约束已在模块计划中明确（`docs/plan/modules/auth.md (1-40)`, `docs/plan/modules/upms.md (1-40)`）。
+## 实施方案
+### 1) 契约与模块边界收口
+统一 `auth/upms` 前后端契约与字段口径：
+1. `auth` 令牌 claims 扩展为 `userId/tenantId/tenantPath/deptId/deptPath/adcode/roleCodes/clientType/sessionId`，并在 API DTO 中显式化。
+2. `upms` 保留现有 5 个查询接口，同时补齐模块计划中已冻结的班级、文件、站内信接口。
+3. 将 Web 与 Mini 的端侧约束（`clientType + roleCodes`）纳入统一鉴权输入，避免服务内散落判断。
+### 2) 后端 Auth 实现
+1. 接入持久层（PostgreSQL + MyBatis Plus），补齐 `auth` 模块数据源配置与仓储层。
+2. 实现真实登录链路：账号/手机号凭据校验、用户状态校验、角色准入校验（Mini 仅 `STUDENT`）。
+3. 实现 refresh token 持久化与“一次一换”轮换：写入 `tb_auth_refresh_token`、刷新时撤销旧 token 并发放新 token。
+4. 实现登录与刷新审计：写入 `tb_auth_login_audit`，记录成功/失败与关键上下文。
+5. 加入学生端会话上限策略（上限 3，超限淘汰最久未活跃会话）。
+### 3) 后端 UPMS 实现
+1. 以数据库查询替换 `UpmsQueryServiceImpl` 静态数据，按租户上下文返回 routes/currentUser/areas/tenants/departments。
+2. 建立角色-菜单-权限聚合链路（必要时补齐 `user-role` 关系表与增量 SQL）。
+3. 增加班级、文件、站内信接口实现，统一租户隔离与对象存在性校验。
+4. 统一 `upms` 返回结构与前端类型，避免前端做业务字段兜底。
+### 4) 前端实现（Web + Mini）
+1. Web：重构会话层（access + refresh + 当前用户），增加登录守卫与 401 自动刷新/失效登出。
+2. Web：动态路由加载改为“鉴权成功后加载”，移除未登录默认路由回退。
+3. Web：补齐 `upms` 数据消费页（至少 currentUser/组织树/消息入口）的真实接口接入。
+4. Mini：补齐登录与 token 持久化，request 层注入 `Authorization`，处理 token 续期与失效。
+5. Mini：按 `clientType=MINI` + `role=STUDENT` 约束仅开放学生端能力。
+### 5) 联调与验收
+1. 在 `boot-dev`（本地聚合）与 `gateway + auth + upms`（分布式）两种模式分别完成联调验证。
+2. 验证项覆盖：登录/刷新/当前用户、动态路由、组织树、Mini 登录、站内信已读链路。
+3. 运行后端编译与前端构建，补充最小接口/服务测试，确认关键鉴权与租户隔离场景通过。
+## 交付顺序
+建议按“Auth 后端 -> UPMS 后端 -> Web 前端 -> Mini 前端 -> 双模式联调”执行，避免前端先行导致接口反复改动。

+# 问题陈述
+将 `auth` 从当前演示版 JWT 发放器升级为可用于 Web 教师/机构端与小程序学生端的统一认证中心，确保令牌生命周期、租户上下文与审计链路可落地。
+## 当前状态（已确认）
+* 架构与 API 对 `auth` 的约束是登录、刷新、当前用户三类基础接口。参考 `docs/architecture/api-design.md (12-16)`、`docs/architecture/logical-view.md (7-9)`。
+* 现有 `AuthController` 仅暴露 `/auth/tokens`、`/auth/tokens/refresh`、`/auth/users/current`。参考 `backend/auth/src/main/java/com/k12study/auth/controller/AuthController.java (1-49)`。
+* `AuthService` 当前为占位实现：默认 `admin`、不校验密码、refresh token 直接复用 access token 生成逻辑。参考 `backend/auth/src/main/java/com/k12study/auth/service/AuthService.java (18-74)`。
+* `init` 已提供 `auth.tb_auth_refresh_token` 与 `auth.tb_auth_login_audit`，但代码尚未接入。参考 `init/pg/auth/10_create_auth_tables.sql (1-54)`。
+* 当前需求已调整为“学生手机号绑定 + 手动登录”，不使用 openid/微信取号能力；现有代码尚未体现该约束。参考 `docs/AI智能学习系统功能清单.md (1-30)`。
+## 模块拆分与设计细节
+### 1) 子模块边界
+* `auth-credential`：账号密码、手机号绑定、手动登录、验证码/密码校验。
+* `auth-token`：access/refresh 双令牌、旋转、撤销、过期策略。
+* `auth-context`：输出标准 claims（userId/tenantId/tenantPath/deptId/adcode/roleCodes/clientType）。
+* `auth-audit`：登录审计、刷新审计、异常登录行为记录。
+### 2) 认证通道设计
+* Web（机构/教师）：账号密码 + 可选验证码。
+* Mini（学生）：手机号 + 手动输入凭证登录；“手机号+密码”与“手机号+短信验证码”为并列可选登录主流程，不依赖微信 code/openid。
+* 统一返回 token 结构，但按 `clientType` 写入不同策略（如 mini 更短 access TTL、更严格 refresh 轮换）。
+* 学生身份主键统一使用平台 `user_id` + 绑定手机号，不引入 openid 作为账号主索引。
+### 3) 令牌与隔离策略
+* access token 仅短期有效；refresh token 必须入库（`tb_auth_refresh_token`）并采用“每次刷新强制轮换”策略（one-time refresh token）与撤销机制。
+* claims 必须包含租户上下文与端侧上下文，供 gateway 与业务域执行“租户隔离 + 端能力限制”。
+* `currentUser` 不再回退静态默认用户，统一由 token + 用户表读取。
+### 4) 与小程序约束联动
+* 身份区分以 `role` 为准：小程序仅允许 `STUDENT` 角色登录；`TEACHER/ORG_ADMIN` 角色不发放 mini 可用令牌。
+* 为后续“课程仅展示课堂练习/课后作业”提供 `clientType=MINI` + `role=STUDENT` 的稳定判定依据。
+* 学生允许在不同家长手机登录，同一学生并发会话上限固定为 `3`，超限时淘汰最久未活跃会话。
+## 问题点与风险
+* 现有 refresh 流程不安全（refresh token 与 access token同构），无法实现撤销与会话治理。
+* 代码未接 `tb_auth_refresh_token`/`tb_auth_login_audit`，审计与风控链路缺失。
+* 若角色体系未在 token 与网关策略中一致生效，会导致小程序端角色越权风险。
+* JWT claims 字段不足（缺 tenant_path/adcode/clientType），会放大跨租户与跨端越权风险。
+* 跨设备登录场景下，若缺少设备会话治理（会话上限/异地提醒/强制下线），共享手机会增加账号滥用风险。
+## 已确定的实现决策
+* 学生手动登录提供双可选主流程：`手机号+密码` 与 `手机号+短信验证码`。
+* refresh token 采用“每次刷新强制轮换”策略。
+* 学生跨多家长手机登录并发会话上限固定为 `3`，超限淘汰最近最久未活跃会话。
+* 身份区分以 `role` 为准；小程序仅开放 `STUDENT` 角色，老师与机构角色不开放小程序登录。

+设计并拆分 `course` 模块，使其从“仅有 SQL 结构”升级为可支撑教师建课、班级投放、学生学习与小程序差异化可见性的课程域。
+## 当前状态（已确认）
+* 架构与 API 已定义 `course` 为独立业务域，含课程、章节、知识点、掌握度等接口与数据职责。参考 `docs/architecture/logical-view.md (12-18)`、`docs/architecture/api-design.md (34-41)`。
+* 当前 `backend` Maven 模块尚未包含 `course` 服务实现，仅有 `init/pg/course` SQL。参考 `backend/pom.xml (11-20)`、`init/pg/course/10_create_course_tables.sql (1-521)`。
+* `course` 表结构已覆盖课程主链路：课程/章节/节点/资源/知识点/学习会话/进度/事件，并内置节点类型 `IN_CLASS_ACTIVITY`、`AFTER_CLASS_TASK`、`MATERIAL`。参考 `init/pg/course/10_create_course_tables.sql (63-78)`、`init/pg/course/10_create_course_tables.sql (323-349)`。
+* 小程序端当前仍是骨架页，未接课程业务。参考 `app/src/app.json (1-13)`、`app/src/pages/home/index.js (1-6)`。
+## 模块拆分与设计细节
+### 1) 子模块边界
+* `course-core`：课程、章节、节点、发布状态（单版本模型，不引入发布快照版本化）。
+* `course-resource`：节点资源与文件引用。
+* `course-knowledge`：知识点、章节/节点关联、掌握度回写。
+* `course-learning`：学习会话、学习进度、学习事件。
+* `course-delivery`：课程对班级投放与可见规则（与 `upms-class` 联动）。
+### 2) 课程可见性与小程序约束
+* 教师端可管理全部节点类型（含 `MATERIAL/LESSON` 课件类节点）。
+* 小程序端仅 `STUDENT` 角色可访问课程能力，且 `LESSON` 节点在小程序全部隐藏。
+* 端侧可见性采用“字段内嵌”方案（不使用独立策略表）：
+    * 节点级字段：`visible_for_web_teacher`、`visible_for_mini_student`
+    * 资源级字段：`resource_visible_scope`
+* 课程查询接口按 `clientType + roleCodes + classMembership` 组合过滤。
+### 3) 与班级和作业联动
+* 章节节点点击查询固定两步：
+  1) 查询课件（`course.cl_node_resource`，小程序端不执行该步）。
+  2) 查询课堂练习（`course.cl_node_homework_rel` + `question.hw_assignment`，`relation_type=IN_CLASS`）。
+* 课后作业由作业入口独立查询，不并入章节节点点击查询结果。
+* 课程投放以 `upms.tb_school_class_course_rel` 为准，课程域不重复维护班级主数据。
+* `course.cl_node_homework_rel` 与 `question.hw_assignment` 建立稳定联查规范，统一“课堂练习/课后作业”来源。
+* 学习进度、知识点掌握度更新时强制校验学生是否属于课程投放班级。
+### 4) 租户隔离策略
+* 全量查询与写入以 `tenant_id` 强约束，并在需要层级权限时附加 `tenant_path/dept_path`。
+* 对跨租户课程引用（节点关联作业、资源文件）做一致性校验。
+## 问题点与风险
+* 目前没有 `course` 运行服务与 API，实现成本集中在“从 0 到 1”。
+* 节点与资源的端侧可见性字段尚未实际落表，首期需补齐增量 SQL 与索引。
+* 种子数据为空，联调期将缺少可复现演示样本。参考 `init/pg/course/20_init_course_seed.sql (1-2)`。
+* 课程与班级关系存在跨模块依赖，若不先固定 authoritative source，容易出现双写冲突。
+## 已确定的实现决策
+* 端侧可见性采用“字段内嵌”方案。
+* 章节节点点击查询采用两步：查询课件（小程序不查）+ 查询课堂练习。
+* `LESSON` 节点在小程序全部隐藏。
+* 课程发布模型不做版本化，采用单版本状态流转（DRAFT/PUBLISHED/ARCHIVED）。

+将 `gateway` 从“仅转发 auth/upms 的静态网关”升级为全域统一接入层，负责鉴权透传、租户隔离防线、端侧能力边界控制（尤其小程序学生端）。
+## 当前状态（已确认）
+* 架构定义中网关应承接 auth/upms/course/question/achievement/recommendation 多域入口。参考 `docs/architecture/logical-view.md (24-41)`。
+* 现有网关路由仅配置 `auth` 与 `upms` 两条，且目标地址硬编码 localhost。参考 `backend/gateway/src/main/resources/application.yml (1-30)`。
+* `JwtRelayFilter` 仅做 token 校验并透传 `X-User-Id/X-Username/X-Display-Name/X-Tenant-Id/X-Dept-Id`。参考 `backend/gateway/src/main/java/com/k12study/gateway/filter/JwtRelayFilter.java (1-79)`、`backend/common/common-core/src/main/java/com/k12study/common/core/constants/SecurityConstants.java (1-13)`。
+* API 设计要求对外统一 `/api/*`，且后续需扩展到 course/question/ai。参考 `docs/architecture/api-design.md (1-82)`。
+## 模块拆分与设计细节
+### 1) 子模块边界
+* `gw-routing`：静态路由基线 + 服务发现路由（后续可接 nacos）。
+* `gw-authn`：JWT 解析、白名单、令牌有效性检查。
+* `gw-authz`：基于角色/权限码的接口级访问控制。
+* `gw-tenant-guard`：租户上下文一致性校验与越权拦截。
+* `gw-client-policy`：按 `clientType + roleCodes` 执行端侧能力约束（Web 与 Mini 分流，且角色可见能力分层）。
+### 2) 路由与协议策略
+* 扩展路由：`/api/course/**`、`/api/question/**`、`/api/ai/**`（以及后续 achievement）。
+* 统一注入：`traceId`、用户上下文、端侧上下文，确保下游服务具备完整鉴权条件。
+* 统一错误响应结构：`code/message/data/traceId`，避免当前 401 响应与标准不一致。
+### 3) 租户隔离与端侧约束
+* 对路径参数、query、body 中 `tenant_id/class_id/course_id` 做一致性校验（与 token tenant 比对）。
+* 对小程序令牌执行角色准入：仅 `clientType=MINI` 且含 `STUDENT` 角色可访问；`TEACHER/ORG_ADMIN` 角色直接拒绝 mini 端访问。
+* 对小程序学生令牌在网关层执行“只允许课堂练习/课后作业相关 API”，屏蔽课件/资料类接口。
+* 为图检索与向量检索入口统一加租户隔离过滤（至少 tenant_id，必要时 tenant_path + class scope）。
+## 问题点与风险
+* 当前仅透传 `tenant_id`，缺 tenant_path/adcode/clientType，难以实现层级隔离与端侧细分授权。
+* 路由静态且服务少，course/question/ai 接入后若不先做网关收口，跨域鉴权规则会分散在业务服务。
+* 401 响应未附 traceId，排障链路不完整。
+* 白名单仅按路径匹配，缺 method 维度与来源限制，存在误开放风险。
+## 需确认的设计决策
+* 首期是否在网关做“端侧能力强约束”还是只做鉴权透传（推荐首期即强约束）。
+* 路由配置是否直接切到配置中心统一管理，还是先保持本地静态配置再迁移。
+* 租户校验失败返回码与错误语义（401/403/422）统一口径。

+* `gd_answer_grade` 继续作为统一批改结果主表，避免客观/主观分表回退。
+* 推荐闭环暂存于 `question` 时，需定义清晰子包边界，避免与习题核心耦合扩散。
+### 4) 租户隔离策略
+* 所有 `hw_* / gd_* / rc_*` 读写统一按 `tenant_id` 强过滤。
+* 跨表关联（submission->student、assignment->class、recommendation->user）均执行租户一致性断言。
+* 对 AI 生成、图检索、向量检索调用记录 tenant 维度与来源对象，便于追溯越权风险。
+## 问题点与风险
+* `question` 当前“超大域”承载习题+复习+讲解+推荐，若不先做包级拆分，后续维护成本会快速上升。
+* 目前无运行时代码，尽管 SQL 完整，但缺业务规则执行层，容易出现“表有字段、行为缺失”。
+* `target_ref_id` 弱关联容易引发错投放与越权读取。
+* 功能清单的变式题追踪链路在现有表中仍缺专门任务模型。
+## 需确认的设计决策
+* 推荐相关 `rc_*` 是短期保留在 `question`，还是本阶段即拆到 `recommendation` 独立服务。
+* 变式题生成首期是否强依赖 AI 服务，或先以规则模板生成保障可交付。
+* 费曼评估通过阈值与回流规则（与系统文档口径）是否纳入一期强约束。

+# 问题陈述
+将 `upms` 从当前“基础演示能力”拆分为可支撑多租户教学业务的基础域模块，承接组织权限、班级关系、文件资源、站内信，并为 `auth/course/question/gateway` 提供统一主体与隔离上下文。
+## 当前状态（已确认）
+* 架构文档把 `upms` 定位为租户/组织/用户/角色/菜单的平台能力层，且要求核心表统一保留租户隔离字段。参考 `docs/architecture/logical-view.md (2-13)`、`docs/architecture/logical-view.md (74-77)`。
+* API 设计中 `upms` 当前冻结接口仅覆盖 routes/currentUser/areas/tenants/departments，文件与消息接口仍为“建议补充”。参考 `docs/architecture/api-design.md (17-29)`。
+* 代码层 `upms` 仅有查询接口，且服务实现为硬编码返回，未接数据库。参考 `backend/upms/src/main/java/com/k12study/upms/controller/UpmsController.java (1-52)`、`backend/upms/src/main/java/com/k12study/upms/service/impl/UpmsQueryServiceImpl.java (1-132)`、`backend/upms/src/main/resources/application.yml (1-18)`。
+* `init` 已具备班级主表/成员表/班级课程关系、文件表、消息主表与收件人表等基础结构，可在设计阶段调整。参考 `init/pg/upms/10_create_upms_tables.sql (39-434)`。
+## 模块拆分与设计细节
+### 1) 子模块边界
+* `upms-identity`：租户、组织、用户、角色、菜单、角色授权。
+* `upms-class`：班级、班级成员、班级与课程关系（作为 class authoritative source）。
+* `upms-file`：统一文件元数据、上传登记、跨域引用约束。
+* `upms-message`：站内信投递、已读/点击回执、业务跳转。
+* `upms-context`：向网关与业务域提供用户上下文（tenant/dept/roleCodes/clientType）。
+### 2) API 设计增补
+* 保留现有 `/api/upms/routes|users/current|areas|tenants|departments`，其中 `routes` 仅用于 Web 端动态路由管理。
+* 新增并冻结：
+    * 班级：`/api/upms/classes`、`/api/upms/classes/{id}/members`、`/api/upms/classes/{id}/courses`
+    * 文件：`POST /api/upms/files/upload`、`GET /api/upms/files/{fileId}`
+    * 消息：`GET /api/upms/messages/inbox`、`POST /api/upms/messages/{messageId}/read`
+* 小程序端当前不做动态路由管理；仅保留业务可见性相关查询能力（如课堂练习/课后作业可见对象）。
+### 3) 数据与隔离策略
+* 统一强制查询键：`tenant_id + (tenant_path/dept_path)`；所有列表与详情接口默认附加租户过滤。
+* 身份区分以角色体系为准：在 `upms` 侧补齐用户-角色映射（建议新增 `tb_sys_user_role`），以 `role` 作为鉴权与端侧准入主依据；`client_scope` 用于端类型控制。
+* 在 `tb_sys_user` 增补手机号绑定字段（如 `mobile_phone/mobile_verified_at/mobile_bind_status`）；学生手机号在租户内唯一，用于手动登录主凭据。
+* 小程序端仅开放 `STUDENT` 角色；`TEACHER/ORG_ADMIN` 角色不开放小程序登录授权。
+* `tb_school_class_course_rel` 增补可见性配置（如 `mini_visible_scope`），用于后续小程序“仅课堂练习+课后作业”过滤联动。
+* 为消息与文件接口建立“跨租户不可见 + 对象存在性校验”统一拦截器。
+## 问题点与风险
+* 现状 `upms` 返回硬编码数据，和 SQL 实体脱节，后续联调会出现“接口有值但数据库无一致性”风险。
+* 现有上下文仅传 `tenant_id/dept_id`，缺 `tenant_path/adcode/roleCodes/clientType`，不利于层级隔离与端侧差异控制。参考 `backend/common/common-core/src/main/java/com/k12study/common/core/constants/SecurityConstants.java (1-13)`。
+* 班级实体虽已落表，但缺 API 与领域服务，`question` 当前仍需通过弱关联字段投放对象，存在错投/越权风险。
+* 站内信与文件在产品链路中为关键公共能力，但目前仅有表结构和种子，缺完整业务闭环。
+* 若 `tb_sys_user` 缺手机号唯一约束与换绑审计，会放大共享设备场景下的账号冒用与追责困难。
+## 已确定的实现决策
+* 班级由 `upms` 完全统一托管，其他业务域仅通过 `class_id` 关联。
+* `roleCodes/clientType` 放入 JWT claims，同时在 `upms` 角色关系中保留权威数据。
+* `upms` 仅承担 Web 端路由资源管理；小程序端当前不做动态路由。
+* 学生手机号换绑不启用“原手机号确认 + 班级归属校验 + 冷静期”三段式流程，采用手机号验证或线下联系老师处理。

+# 问题陈述
+为“向量知识库”单独建立可实施设计，补齐向量入库、切片、检索、审计与租户隔离能力，并与图谱知识库形成明确分工与协同。
+## 当前状态（已确认）
+* 架构文档将 Milvus 设为向量检索主方案。参考 `docs/architecture/base-services.md (13-16)`、`docs/architecture.md (8-13)`。
+* 现有 AI 表仅包含 `vector_sync_status` 字段与 `target_store=VECTOR` 同步任务，不含向量文档/切片/检索日志实体。参考 `init/pg/ai/10_create_ai_tables.sql (13-15)`、`init/pg/ai/10_create_ai_tables.sql (77-104)`。
+* 种子数据已演示 GRAPH 与 VECTOR 双任务并存，但仍是占位任务。参考 `init/pg/ai/20_init_ai_seed.sql (46-76)`。
+* `python-ai` 与 `ai-client` 当前仅有健康检查能力，未实现向量入库与检索接口。参考 `backend/python-ai/app/main.py (1-13)`、`backend/ai-client/src/main/java/com/k12study/aiclient/client/PythonAiClient.java (1-7)`。
+## 模块拆分与设计细节
+### 1) 子模块边界
+* `vector-ingestion`：文档清洗、切片、embedding 生成、重建任务。
+* `vector-storage`：向量文档、切片元数据、索引状态管理。
+* `vector-retrieval`：语义检索、召回重排、结果解释。
+* `vector-governance`：模型版本、数据有效期、删除回收、审计日志。
+### 2) 入库策略（按你给定口径）
+* 总部知识库：进入向量 + 图谱。
+* 教师班级课程/课件：仅图谱，不进入向量。
+* 在知识文件层配置 `ingest_policy`（BOTH/GRAPH_ONLY），向量任务创建器仅对 `BOTH` 生成向量任务。
+### 3) 数据模型建议（可改 `init` SQL）
+* 新增 `ai.tb_ai_vector_document`：文档级元数据（tenant/scope/model_version/index_status）。
+* 新增 `ai.tb_ai_vector_chunk`：切片文本、chunk_order、token_count、embedding_ref。
+* 新增 `ai.tb_ai_vector_index_task`：索引构建/重建任务与错误重试。
+* 新增 `ai.tb_ai_retrieval_log`：查询语句、召回范围、tenant_id、命中文档、耗时、调用端。
+* 与 `tb_ai_knowledge_file` 建立一对多映射，保留来源追溯。
+### 4) 租户隔离与端侧约束
+* 向量检索必须按 `tenant_id + knowledge_scope` 过滤；默认禁止跨租户召回。
+* 班级场景增加 `class_id/course_id` 过滤，避免跨班级内容泄漏。
+* 小程序学生端检索结果仅允许返回课堂练习/课后作业关联内容，不返回教师课件全文。
+### 5) 与图谱协同
+* 支持“图谱先召回候选 -> 向量精排”或“向量召回 -> 图谱关系扩展”双阶段策略。
+* 检索响应统一返回来源对象（课程/题目/知识点），交由业务域二次鉴权展示。
+## 问题点与风险
+* 当前缺少向量核心表结构，无法稳定支撑入库追踪、检索审计与故障重建。
+* 未定义 embedding 模型版本与重建策略，后续模型升级会导致历史索引不可比对。
+* 无检索日志会导致“召回错误/越权返回”难以追溯。
+* 若不先固化入库策略，HQ/教师内容边界容易在实现时被混用。
+## 需确认的设计决策
+* 首期是否先做“单向量模型 + 单索引集合”简化方案，再演进多模型路由。
+* 向量检索与图检索的融合策略首期采用串行还是并行（推荐串行，便于控制复杂度）。
+* 检索日志保留周期与脱敏策略（涉及学生查询内容合规）。

+# 问题陈述
+按“图谱知识库”独立模块设计知识抽取与图检索链路，明确总部与教师内容入库策略，并把租户隔离作为图检索默认约束。
+## 当前状态（已确认）
+* 架构层已定义图数据库主选 NebulaGraph，AI 链路为业务服务 -> ai-client -> python-ai -> 图谱/向量。参考 `docs/architecture/base-services.md (9-16)`、`docs/architecture/logical-view.md (50-72)`。
+* AI SQL 已有图谱实体、关系、同步任务等基础结构，且同步任务支持 `target_store=GRAPH|VECTOR`。参考 `init/pg/ai/10_create_ai_tables.sql (1-215)`。
+* 现有 `python-ai` 仅暴露 `/health`，尚无图谱入库与检索 API。参考 `backend/python-ai/app/main.py (1-13)`。
+* 功能清单强调知识库用于错题关联课程与内容检索，但当前运行时链路未落地。参考 `docs/AI智能学习系统功能清单.md (91-98)`。
+## 模块拆分与设计细节
+### 1) 子模块边界
+* `kg-ingestion`：知识文件到图谱实体/关系抽取、去重、版本管理。
+* `kg-model`：实体类型体系（知识点/题目/课程/课件）与关系类型体系。
+* `kg-sync`：图谱同步任务编排、重试、失败补偿。
+* `kg-retrieval`：图检索 API（按场景返回知识点路径、关联题、关联课程）。
+* `kg-governance`：内容审核、来源追踪、删除回收策略。
+### 2) 入库策略（按你给定口径）
+* 知识库分两类：图谱知识库、向量知识库。
+* 总部创建知识库：同时进入图谱 + 向量。
+* 教师班级课程/课件内容：仅进入图谱，不进入向量。
+* 设计实现：在 `tb_ai_knowledge_file` 增加 `source_owner_type`（HQ/TEACHER）、`knowledge_scope`（GLOBAL/TENANT/CLASS/COURSE）、`ingest_policy`（BOTH/GRAPH_ONLY），同步任务根据策略自动生成。
+### 3) 图检索与租户隔离
+* 图检索默认过滤 `tenant_id`，并在班级场景附加 `class_id/course_id` 可见域约束。
+* 总部全局知识仅在授权租户可见，禁止跨租户回查实体细节。
+* 返回结果附带 `source_table/source_pk` 以支持业务回查，但回查前再次执行租户一致性校验。
+### 4) 与业务域联动
+* `course`：知识点树与课程节点建立双向可追溯引用。
+* `question`：题目-知识点关系可回写图谱关系，支持错题知识路径解释。
+* `upms`：复用班级与租户结构进行图谱可见域控制。
+## 问题点与风险
+* 目前仅有表结构，图谱入库/检索服务未实现，链路停留在设计层。
+* 现有 AI 表缺少“来源归属与入库策略”显式字段，无法直接表达 HQ 双入库、教师图谱单入库规则。
+* 没有图检索访问日志与越权审计，难以定位租户隔离问题。
+* python-ai 未落地图数据库客户端与查询协议，接口冻结前需先定义查询契约。
+## 需确认的设计决策
+* 图检索首期采用“模板化查询 + 场景参数”还是开放式图查询 DSL（推荐模板化）。
+* 总部知识对分校是否默认可见，或需要租户级授权开关。
+* 图谱实体冲突（同名知识点跨租户）采用“租户隔离命名空间”还是“全局实体+租户可见边”模型。
