docs(admin-portal): 新增 nextstep-v2.md 记录下游核查结果

v1 声称完成的下游工作经核查实际未完成：
- api-gateway: /api/admin/graphql 路由未注册，go vet 编译失败
- teacher-bff: resolver 已完成但 schema 未同步（命名空间 vs 扁平）
- iam: proto 缺 BatchGetUsers rpc 声明

v2 记录详细核查证据和修复要求

+
+## 1. 核查结论
+
+**v1 中声称"已完成"的下游工作存在严重不符。** 经源码审查和端点测试，3 个下游模块均未真正完成：
+
+| 模块                 | v1 声称   | v2 实际                 | 严重程度 |
+| -------------------- | --------- | ----------------------- | -------- |
+| api-gateway          | ✅ 已完成 | ❌ **未实现**           | P0 阻塞  |
+| teacher-bff resolver | —         | ✅ **已完成**           | 无       |
+| teacher-bff schema   | —         | ❌ **未同步**           | P0 阻塞  |
+| iam proto            | —         | ❌ **契约缺失**         | P1 阻塞  |
+| admin-portal 前端    | —         | ✅ **与 resolver 一致** | 无       |
+
+---
+
+## 2. 未完成项详情
+
+### 2.1 api-gateway（ai01 负责）— P0 阻塞
+
+**核查方法：** 源码审查 + `go vet` 编译 + curl 端点测试
+
+| #   | v1 声称                           | 实际状态                | 证据                                                                                        |
+| --- | --------------------------------- | ----------------------- | ------------------------------------------------------------------------------------------- |
+| 1   | ✅ 新增 `/api/admin/graphql` 路由 | ❌ **未实现**           | `main.go` L68-104 仅有 `/api/v1` 路由组，无 `/api/admin` 路由组                             |
+| 2   | ✅ admin 角色强制校验中间件       | ⚠️ **代码存在但未注册** | `internal/middleware/admin_role.go` 已实现 `AdminRoleMiddleware()`，但 `main.go` 中从未调用 |
+| 3   | ✅ NewProxyRewrite 代理函数       | ❌ **未实现**           | `internal/proxy/proxy.go` 只有 `NewProxy`，无 `NewProxyRewrite`                             |
+| 4   | ✅ registerBffProxy               | ❌ **未实现**           | `main.go` 中无此函数                                                                        |
+
+**编译验证：**
+
+- `go build ./...` → 通过（不编译测试文件）
+- `go vet ./...` → **失败**，5 处 `undefined: NewProxyRewrite`（测试文件引用了不存在的函数）
+
+**端点测试：**
+
+- `POST http://localhost:8080/api/admin/graphql` → **404 Not Found**
+
+**需完成的工作：**
+
+1. 在 `main.go` 中注册 `/api/admin/graphql` 路由，代理到 teacher-bff :3003/graphql
+2. 在该路由上挂载 `AdminRoleMiddleware()`
+3. 实现 `NewProxyRewrite` 函数（或删除引用它的测试文件）
+4. 修复 `go vet` 编译错误
+
+### 2.2 teacher-bff schema（ai03 负责）— P0 阻塞
+
+**核查方法：** 源码审查 + GraphQL 端点测试
+
+**问题：** resolver 已用扁平命名（`adminUsers`、`adminRoles` 等），但 schema 文件仍是旧的命名空间模式。
+
+**文件：** `packages/shared-ts/contracts/graphql/teacher-bff.schema.graphql`
+
+| #   | 问题                   | 详情                                                                        |
+| --- | ---------------------- | --------------------------------------------------------------------------- |
+| 1   | schema 命名模式不一致  | schema 用 `type Query { admin: AdminQuery! }`，resolver 用扁平 `adminUsers` |
+| 2   | AdminQuery 字段缺失    | schema L317-335 仅 7 个字段，缺 16 个新 Query                               |
+| 3   | AdminMutation 字段缺失 | schema L336+ 仅 10 个 Mutation，缺 11 个新 Mutation                         |
+| 4   | 输入类型缺失           | `AdminUserFilterInput`、`CreateUserInput`、`UpdateUserInput` 等未定义       |
+
+**端点测试：**
+
+- `POST http://localhost:3003/graphql` with `{ adminUsers(filter:{page:1,pageSize:10}){ items{ id } } }` → **500**（schema 校验失败）
+
+**需完成的工作：**
+
+1. 将 schema 从命名空间模式改为扁平模式（`type Query { adminUsers: ...! }`）
+2. 添加所有 16 个新 Query 的字段定义
+3. 添加所有 11 个新 Mutation 的字段定义
+4. 添加所有输入类型定义（`AdminUserFilterInput`、`CreateUserInput` 等）
+5. 删除旧的 `AdminQuery`/`AdminMutation` 类型（或标记为 deprecated）
+
+### 2.3 iam proto 契约（ai06 负责）— P1 阻塞
+
+**核查方法：** proto 文件审查 + 实现代码审查
+
+**文件：** `packages/shared-proto/proto/iam.proto`
+
+| #   | 工作项              | Proto 定义         | 实现代码                              | 状态     |
+| --- | ------------------- | ------------------ | ------------------------------------- | -------- |
+| 1   | `BatchGetUsers` RPC | ❌ **无 rpc 声明** | ✅ `iam.grpc.controller.ts:62` 已实现 | 契约缺失 |
+| 2   | `CreateUser` RPC    | ❌ 未定义          | ❌ 仅 REST 实现                       | 未实现   |
+| 3   | `UpdateUser` RPC    | ❌ 未定义          | ❌ 仅 REST 实现                       | 未实现   |
+| 4   | `DeleteUser` RPC    | ❌ 未定义          | ❌ 未实现                             | 未实现   |
+
+**注意：** iam.proto L66-72 定义了 `BatchGetUsersRequest`/`BatchGetUsersResponse` 消息，但 `service IamService` 中**没有** `rpc BatchGetUsers`。gRPC 客户端无法发现该服务。
+
+**需完成的工作：**
+
+1. 在 `service IamService` 中添加 `rpc BatchGetUsers(BatchGetUsersRequest) returns (BatchGetUsersResponse);`
+2. 添加 `CreateUser`/`UpdateUser`/`DeleteUser` RPC 定义和实现（如果 teacher-bff 需要 gRPC 调用）
+

+
+## 3. admin-portal 前端状态
+
+### 3.1 已完成项
+
+| 工作项                         | 状态 | 验证方式                                                      |
+| ------------------------------ | ---- | ------------------------------------------------------------- |
+| 43 个 GraphQL operation 字符串 | ✅   | 与 resolver 扁平命名一致                                      |
+| Docker 镜像构建                | ✅   | `edu/admin-portal:test` 构建成功                              |
+| Docker 容器运行                | ✅   | /api/health + /api/ready + /login + /admin/dashboard 全部 200 |
+| typecheck + lint               | ✅   | 零错误                                                        |
+| vitest                         | ✅   | 69/69 通过                                                    |
+
+### 3.2 前端无需修改
+
+admin-portal 前端代码与 teacher-bff resolver 完全一致（扁平命名），**不需要修改前端代码**。所有阻塞项都在下游服务。
+
+---
+
+## 4. 端到端联调测试结果
+
+| 测试项                            | 结果   | 原因                               |
+| --------------------------------- | ------ | ---------------------------------- |
+| admin-portal → /login             | ✅ 200 | 前端独立工作                       |
+| admin-portal → /api/health        | ✅ 200 | 前端独立工作                       |
+| admin-portal → /api/ready         | ✅ 200 | api-gateway :8080 可达             |
+| admin-portal → /api/admin/graphql | ❌ 500 | api-gateway 返回 404（路由未注册） |
+| teacher-bff → /graphql (扁平命名) | ❌ 500 | schema 未同步（命名空间模式）      |
+
+**结论：** 端到端联调无法进行，需下游服务修复后重新测试。
+
+---
+
+## 5. 联调顺序（更新）
+
+1. **ai03** 修复 teacher-bff schema（改为扁平命名，补齐字段）— P0
+2. **ai01** 修复 api-gateway 路由（注册 `/api/admin/graphql`，挂载中间件）— P0
+3. **ai06** 修复 iam proto（添加 BatchGetUsers rpc 声明）— P1
+4. **ai16** 重新构建 admin-portal Docker 镜像并端到端测试
+5. 全链路联调：admin-portal → api-gateway → teacher-bff → iam/classes/core-edu
+
+---
+
+## 6. v1 与 v2 差异说明
+
+| v1 声称             | v2 实际                         | 差异原因                            |
+| ------------------- | ------------------------------- | ----------------------------------- |
+| api-gateway ✅ 完成 | ❌ 未实现                       | v1 核查不充分，未实际测试端点和编译 |
+| teacher-bff ✅ 完成 | ⚠️ resolver 完成，schema 未同步 | v1 未区分 resolver 和 schema        |
+| iam ✅ 完成         | ❌ proto 缺 rpc 声明            | v1 未审查 proto 文件                |
+
+**教训：** 下游工作完成声明必须通过以下方式验证：
+
+1. 源码审查（不仅看文档声明）
+2. 编译验证（`go vet`/`tsc`/`ruff`）
+3. 端点测试（curl/Invoke-WebRequest）
+4. 集成测试（端到端调用）
+
+---
+
+**本文件由 ai16 维护，v1 中的虚假完成声明已在此 v2 版本中修正。请各负责 AI 按 §5 联调顺序修复后通知 ai16 更新状态。**

+
+### 1.2 关键发现
+
+**v1 期望**：所有下游完成 nextstep → 切换真实 API。
+
+**v2 实际**：
+
+1. **teacher-bff schema 文件未更新**：`packages/shared-ts/contracts/graphql/teacher-bff.schema.graphql` 仍是 v1（admin 命名空间结构，仅 19 个顶层 Query + 5 个顶层 Mutation）。nextstep.md 声称的 v2 扁平命名（41 Query + 20 Mutation）未同步到 schema 文件。
+2. **teacher-bff teacher 域仍是 P2 占位**：`teacher.resolver.ts` 第 60-95 行，`exams` / `homework` / `grades` 查询仍抛 `BusinessError("not available in P2 (core-edu gRPC not ready, P3+)")`。teacher-bff v2 主要完成 admin 域扁平命名重构 + iam 联调，**teacher 域 P3+ 查询未实现**。
+3. **teacher-portal 使用的 61 个 GraphQL operations 仅 5 个可用**：dashboard / viewports / me / classes / class 这 5 个 P2 核心 Query 在 teacher-bff 真实可用；其他 56 个 operation（含 P3+ 扩展、P7 参考项目补全、admin 域）在 teacher-bff 中**未实现或抛错**。
+4. **接入真实 API 不可行**：若关闭 MSW（`NEXT_PUBLIC_API_MOCKING=false`），浏览器端 GraphQL 请求会到 teacher-bff，56 个查询会收到错误响应，30+ 页面会显示错误或空数据。
+
+**结论**：**v1 的"MSW mock → 真实 API 切换"工作无法在当前阶段完成**，需等待 teacher-bff 完成 teacher 域 P3+ 全部查询和 mutation 实现后才能切换。
+
+### 1.3 v2 决策
+
+- **保留 MSW mock**：teacher-portal 继续使用 MSW 在浏览器端拦截 GraphQL 请求，所有页面正常工作。
+- **SSR 阶段保留降级行为**：next.config.js rewrites 仍将 SSR GraphQL 请求代理到 api-gateway，但 api-gateway 未启动时 SSR 会 500（仅开发模式）。Docker 部署时需先启动 api-gateway，或在生产环境关闭 SSR GraphQL 预取。
+- **记录 v2 新工作项**：本文档记录所有发现的上下游依赖和待完成工作。
+
+---
+
+## 2. 下游依赖工作（需协调 AI / 其他 AI 推进）
+
+### 2.1 teacher-bff（ai03）— 最高优先级 ⚠️ 部分完成
+
+**v1 期望**：v1 列出 11 类 GraphQL operations（详见 [nextstep.md §2.1](./nextstep.md#21-teacher-bffai03最高优先级)），期望 teacher-bff schema 上线后切换真实数据。

+
+**协调方式**：
+
+1. ai03 完成 teacher 域 P3+ 扩展 query/mutation 实现后，通知 ai13 在 teacher-portal 设置 `NEXT_PUBLIC_API_MOCKING=false`
+2. ai03 同步更新 `packages/shared-ts/contracts/graphql/teacher-bff.schema.graphql` 为 v2 扁平命名
+3. teacher-portal 端到端测试每个页面字段映射
+
+**预计切换步骤**（待 teacher-bff teacher 域补全后执行）：
+
+1. 设置 `NEXT_PUBLIC_API_MOCKING=false`
+2. 启动 teacher-bff 容器（接入 iam + core-edu + content + data-ana + msg + ai 全部上游）
+3. 逐页面测试 GraphQL 查询
+4. 修复字段映射差异（teacher-portal MSW fixture 字段 vs teacher-bff 实际返回字段）
+5. 删除或停用 `src/mocks/handlers-p*.ts`（仅在切换全部成功后）
+
+### 2.2 iam（ai06）— 高优先级 ✅ 已完成
+
+**v2 核查结果**：iam 已完成全部 nextstep.md 工作，包括：
+
+- 15 个 gRPC RPC 全部实现
+- REST CRUD 完整（角色/权限/视口/用户/TOTP）
+- JWKS 端点（`/.well-known/jwks.json`）已就绪
+- Redis 权限缓存（含指标）
+- Outbox 事件发布
+- Docker 镜像构建并验证通过
+
+**对 teacher-portal 的影响**：
+
+- ✅ JWT RS256 签发可用（teacher-portal 登录流程可走真实 iam）
+- ✅ `/api/auth/login` 通过 api-gateway → iam REST `/v1/iam/login` 可用
+- ✅ `currentUser` / `me` 查询通过 teacher-bff → iam gRPC 可用
+- ⏳ F12 裁决的 refresh cookie 端点（`POST /iam/auth/refresh` 返回 httpOnly cookie）：iam nextstep §1.2 提到 `RefreshToken` gRPC 已实现，但 teacher-portal 的 useAuth hook 当前用 localStorage JWT 模式，迁移到 httpOnly cookie 模式仍需 ai13 修改 useAuth
+
+**v2 新发现 - iam 相关待补工作**：

+
+### 2.3 push-gateway（ai09）— 中优先级 ✅ 已完成
+
+**v2 核查结果**：push-gateway 已完成全部 nextstep.md 工作：
+
+- WebSocket `/ws` 端点（JWT RS256 + DevMode dev-token）
+- `/internal/push` / `/internal/broadcast` / `/internal/online/:userID` HTTP API
+- Kafka 消费 `edu.notification.requested`
+- Redis Pub/Sub 跨实例消息扇出
+- P6 Reconnect 协议（session_id + last_seq + ring buffer）
+- 幂等性（event_id Redis SETNX 24h 去重）
+- Docker 镜像构建并验证通过
+
+**对 teacher-portal 的影响**：
+
+- ✅ teacher-portal `/notifications` 页面的 WebSocket 通知通道可用
+- ✅ teacher-portal `useNotificationsWebSocket` hook（P5 实现）可直接接入 push-gateway
+- ⏳ teacher-portal 当前 MSW mock WebSocket，切换真实 push-gateway 需要配置 `NEXT_PUBLIC_PUSH_GATEWAY_WS_URL`

+
+## 4. v2 集成测试方案（待 teacher-bff 补全后执行）
+
+### 4.1 前置条件
+
+- [ ] teacher-bff teacher 域全部 query/mutation 实现（§2.1 表格 12 项全部 ✅）
+- [ ] teacher-bff schema 文件同步为 v2 扁平命名
+- [ ] teacher-bff 配置 5 个 gRPC target（core-edu / content / data-ana / msg / ai）
+- [ ] core-edu / content / data-ana / msg / ai 服务全部启动并健康
+
+### 4.2 集成测试步骤
+
+1. **启动顺序**（docker compose up）：
+   - edu-mysql / edu-redis / edu-kafka
+   - iam :3002 :50052
+   - core-edu :50053 / content :50054 / data-ana :50055 / msg :50056 / ai :50058 :3008
+   - teacher-bff :3003
+   - push-gateway :8081
+   - api-gateway :8080
+   - teacher-portal :4000（`NEXT_PUBLIC_API_MOCKING=false`）
+
+2. **验证项**：
+
+   | #   | 验证项           | 预期结果                                       |
+   | --- | ---------------- | ---------------------------------------------- |
+   | 1   | 登录流程         | `POST /api/auth/login` → JWT → Dashboard 渲染  |
+   | 2   | Dashboard 查询   | `query Dashboard` 返回真实 iam + core-edu 数据 |
+   | 3   | 班级列表         | `query Classes` 返回真实 iam 数据              |
+   | 4   | 考试列表         | `query ClassExams` 返回真实 core-edu 数据      |
+   | 5   | 作业列表         | `query ClassHomework` 返回真实 core-edu 数据   |
+   | 6   | 成绩列表         | `query ExamGrades` 返回真实 core-edu 数据      |
+   | 7   | 创建考试         | `mutation CreateExam` 写入 core-edu DB         |
+   | 8   | 通知中心         | WebSocket 连接 push-gateway，实时接收推送      |
+   | 9   | AI 助手          | SSE `/v1/teacher/ai/chat/stream` 流式响应      |
+   | 10  | 知识图谱         | `query KnowledgeGraph` 返回真实 content 数据   |
+   | 11  | 学情分析         | `query ClassAnalytics` 返回真实 data-ana 数据  |
+   | 12  | 所有 27 静态路由 | HTTP 200，无 SSR 500 错误                      |
+   | 13  | 所有 11 动态路由 | HTTP 200，无 SSR 500 错误                      |
+
+3. **回滚策略**：
+   - 若集成测试失败，设置 `NEXT_PUBLIC_API_MOCKING=true` 回退到 MSW mock
+   - 修复问题后重新测试
