+
+## §1 当前状态
+
+P5 实现已完成。8 RPC 全部实现，gRPC 拦截器已修复为异步兼容，下游 gRPC 客户端已从 Mock 切换为真实 gRPC 调用。377 个测试通过，覆盖率 88%。
+
+### 已完成
+
+- [x] ai.proto 8 RPC 完整版（含 GetLessonPlanStatus / ConfirmLessonPlan）
+- [x] events.proto AIUsageEvent 补全
+- [x] gRPC server 端口 50058，异步拦截器（Logging + Auth + Error）
+- [x] HTTP 10 端点（/v1/ai 前缀，ActionState 信封）
+- [x] LLM Provider FailoverChain（OpenAI / Anthropic / 百川 / Ollama + 熔断 + 故障切换）
+- [x] 评估三道防线（RuleValidator + LLMJudge + QualityGate）
+- [x] 用量记录（Redis）+ Kafka 事件发布 + 配额管理
+- [x] 安全层（PII + 输入清洗 + 输出审核）
+- [x] 下游 gRPC 客户端真实调用（content / data-ana / iam，不再使用 Mock）
+- [x] 备课工作流（4 步编排 + Redis 状态存储）
+- [x] Dockerfile 多阶段构建 + docker-compose.deploy.yml 环境变量补全

+
+---
+
+## 1. v2 核查总结
+
+### 1.1 核查范围
+
+并行核查了 7 个上游模块的 nextstep-v2.md：
+
+| 模块           | 负责人 | 文档位置                                                                                    | v2 对 api-gateway 的要求                         | 核查结果  |
+| -------------- | ------ | ------------------------------------------------------------------------------------------- | ------------------------------------------------ | --------- |
+| admin-portal   | ai16   | [apps/admin-portal/docs/nextstep-v2.md](../../../apps/admin-portal/docs/nextstep-v2.md)     | `/api/admin/graphql` 路由 + AdminRoleMiddleware  | ✅ 已完成 |
+| teacher-portal | ai13   | [apps/teacher-portal/nextstep-v2.md](../../../apps/teacher-portal/nextstep-v2.md)           | `/api/v1/teacher/*` 反向代理                     | ✅ 已完成 |
+| student-portal | ai14   | [apps/student-portal/docs/nextstep-v2.md](../../../apps/student-portal/docs/nextstep-v2.md) | `/api/v1/student/*` 反向代理 + 路径重写          | ✅ 已完成 |
+| parent-portal  | ai15   | [apps/parent-portal/docs/nextstep-v2.md](../../../apps/parent-portal/docs/nextstep-v2.md)   | Docker 构建修复                                  | ✅ 已完成 |
+| teacher-bff    | ai03   | [services/teacher-bff/docs/nextstep-v2.md](../../teacher-bff/docs/nextstep-v2.md)           | `/api/v1/teacher/*` + `/api/admin/graphql` 代理  | ✅ 已完成 |
+| student-bff    | ai04   | [services/student-bff/docs/nextstep-v2.md](../../student-bff/docs/nextstep-v2.md)           | `/api/v1/student/*` 路径重写剥离 /api/v1/student | ✅ 已完成 |
+| parent-bff     | ai04   | [services/parent-bff/docs/nextstep-v2.md](../../parent-bff/docs/nextstep-v2.md)             | `/api/v1/parent/*` 路径重写剥离 /api/v1/parent   | ✅ 已完成 |
+
+### 1.2 v2 关键发现
+
+**admin-portal v2 核查发现**：v1 声称已完成的工作（admin 路由、AdminRoleMiddleware、NewProxyRewrite、registerBffProxy）在代码中**实际缺失**（可能被回滚）。v2 重新实现并验证通过。
+
+**parent-bff v2 核查发现**：parent-bff GraphQL 端点路径采用 ARB-022 §24.4 ISSUE-003 方案 A（双 /v1 前缀），即 `/api/v1/parent/v1/graphql` → 剥离 `/api/v1/parent` → `/v1/graphql`。api-gateway 的 `registerBffProxy` 已支持此路径重写。
+
+### 1.3 本地 Docker 验证结果（2026-07-14 v2）
+
+测试环境：本地 Docker（edu/api-gateway:test 容器，DEV_MODE=true，端口 18080→8080）
+
+```
+镜像：edu/api-gateway:test（golang:1.25-alpine builder + alpine:3.20 runner）
+容器：edu-api-gateway-test（DEV_MODE=true, PORT=8080）
+```

+## 2. v2 完成项详情
+
+### 2.1 admin-portal P0 阻塞项（重新实现）
+
+**来源**：[admin-portal nextstep-v2.md](../../../apps/admin-portal/docs/nextstep-v2.md) §2.1
+
+| #   | 工作项                         | 状态 | 实现详情                                                                                                         |
+| --- | ------------------------------ | ---- | ---------------------------------------------------------------------------------------------------------------- |
+| 1   | 新增 `/api/admin/graphql` 路由 | ✅   | [main.go](../main.go) L110-129 新增 `/api/admin` 路由组，POST /api/admin/graphql 代理到 teacher-bff:3003/graphql |
+| 2   | admin 角色强制校验中间件       | ✅   | [admin_role.go](../internal/middleware/admin_role.go) `AdminRoleMiddleware`，校验 x-user-roles 含 admin 角色     |
+| 3   | 路径对齐契约 §2.3              | ✅   | /api/admin/graphql 为唯一入口，路径重写 /api/admin/graphql → /graphql（teacher-bff @Controller("graphql")）      |
+| 4   | AdminRoleMiddleware 单元测试   | ✅   | [admin_role_test.go](../internal/middleware/admin_role_test.go) 8 个测试（含角色列表/空值/大小写）               |
+
+**中间件链**：熔断（teacher-bff-admin）→ JWT 鉴权 → AdminRoleMiddleware → 指标 → 反向代理
+
+### 2.2 BFF 路由路径重写修复（重新实现）
+
+**来源**：[student-bff nextstep-v2.md](../../student-bff/docs/nextstep-v2.md) §3.1、[parent-bff nextstep-v2.md](../../parent-bff/docs/nextstep-v2.md) §3.1
+
+**问题**：teacher-bff / student-bff 的 GraphQL 端点在 `/graphql`（`@Controller("graphql")`），parent-bff 在 `/v1/graphql`（ARB-022 §24.4 ISSUE-003 方案 A）。原代理仅剥离 `/api` 前缀，导致下游收到 `/v1/teacher/graphql` 而非 `/graphql`，返回 404。
+
+**修复**：新增 `registerBffProxy` 函数，对 BFF 路由（teacher/student/parent）剥离 `/api/v1/{bff}` 前缀，仅转发剩余路径到下游。
+
+| 路由                        | 路径重写               | 下游接收路径  | 下游服务         |
+| --------------------------- | ---------------------- | ------------- | ---------------- |
+| `/api/v1/teacher/graphql`   | 剥离 `/api/v1/teacher` | `/graphql`    | teacher-bff:3003 |
+| `/api/v1/student/graphql`   | 剥离 `/api/v1/student` | `/graphql`    | student-bff:3009 |
+| `/api/v1/parent/v1/graphql` | 剥离 `/api/v1/parent`  | `/v1/graphql` | parent-bff:3010  |
+| `/api/admin/graphql`        | 剥离 `/api/admin`      | `/graphql`    | teacher-bff:3003 |
+
+**关键文件**：
+
+- [main.go](../main.go) L180-198 `registerBffProxy` 函数
+- [proxy.go](../internal/proxy/proxy.go) L31-49 `NewProxyRewrite` 函数
+- [proxy_rewrite_test.go](../internal/proxy/proxy_rewrite_test.go) 5 个测试（路径剥离/查询参数/无效URL/请求体/请求头）
+
+### 2.3 Dockerfile 修复
+
+**问题**：
+
+1. go.work 引用了 push-gateway，但 Docker 构建上下文仅含 api-gateway + shared-go，导致 `go mod download` 失败
+2. 容器内无法访问 proxy.golang.org，需使用国内代理
+
+**修复**：
+
+- 生成精简版 go.work（仅 api-gateway + shared-go）
+- 设置 `GOPROXY=https://goproxy.cn,direct` + `GOSUMDB=off`
+- 构建上下文改为仓库根目录（访问 packages/shared-go）

+
+## 1. 概述
+
+api-gateway 是 Edu 系统统一入口（L3 网关层），负责路由转发、JWT RS256 验签、限流、熔断、CORS、可观测性。本文档记录基于上游 4 个前端 portal 模块（teacher-portal / student-portal / parent-portal / admin-portal）的下游依赖分析，梳理 api-gateway 已完成工作与剩余阻塞项。
+
+**本地 Docker 测试结果（2026-07-13）：**
+
+- ✅ 镜像构建成功（`edu/api-gateway:test`，golang:1.25-alpine + 多阶段构建）
+- ✅ 容器启动正常（端口 8080，DevMode）
+- ✅ `/healthz` 返回 200
+- ✅ `/readyz` 返回 503（下游未启动时正确报告不可达）
+- ✅ `/metrics` 返回 200 + Prometheus 格式（7 个业务指标可见）
+- ✅ `/api/admin/graphql` 无 auth → 401（AuthMiddleware 拦截）
+- ✅ `/api/admin/graphql` dev-token → 502（路由存在，admin 角色通过，下游 teacher-bff 不可达）
+- ✅ `/api/v1/teacher/graphql` dev-token → 502（路由存在，BFF 路径重写正确，下游不可达）
+- ✅ go vet + go build + go test 全部通过（13 个新测试）
+
+---
+
+## 2. 已完成工作（基于上游 portal 依赖分析）
+
+### 2.1 admin-portal P0 阻塞项（已解决）
+
+**来源**：[admin-portal nextstep.md](../../../apps/admin-portal/docs/nextstep.md) §2.1
+
+| #   | 工作项                         | 状态 | 实现详情                                                                                         |
+| --- | ------------------------------ | ---- | ------------------------------------------------------------------------------------------------ |
+| 1   | 新增 `/api/admin/graphql` 路由 | ✅   | main.go 新增 `/api/admin` 路由组，POST /api/admin/graphql 代理到 teacher-bff:3003/graphql        |
+| 2   | admin 角色强制校验中间件       | ✅   | 新增 `AdminRoleMiddleware`（internal/middleware/admin_role.go），校验 x-user-roles 含 admin 角色 |
+| 3   | 路径对齐契约 §2.3              | ✅   | /api/admin/graphql 为唯一入口，路径重写 /api/admin/graphql → /graphql（teacher-bff @Controller） |
+
+**关键文件**：
+
+- [main.go](../main.go)（L107-126，admin 路由组注册）
+- [internal/middleware/admin_role.go](../internal/middleware/admin_role.go)（AdminRoleMiddleware 实现）
+- [internal/proxy/proxy.go](../internal/proxy/proxy.go)（NewProxyRewrite 路径重写代理）
+
+### 2.2 BFF 路由路径重写修复（已解决）
+
+**来源**：[student-portal nextstep.md](../../../apps/student-portal/docs/nextstep.md) §2、[teacher-portal nextstep.md](../../../apps/teacher-portal/nextstep.md) §4.3
+
+**问题**：teacher-bff / student-bff / parent-bff 的 GraphQL 端点在 `/graphql`（@Controller("graphql")），但原代理仅剥离 `/api` 前缀，导致下游收到 `/v1/teacher/graphql` 而非 `/graphql`，返回 404。
+
+**修复**：新增 `registerBffProxy` 函数，对 BFF 路由（teacher/student/parent）剥离 `/api/v1/{bff}` 前缀，仅转发剩余路径到下游。
+
+| 路由                    | 修复前（错误）                              | 修复后（正确）               |
+| ----------------------- | ------------------------------------------- | ---------------------------- |
+| /api/v1/teacher/graphql | → teacher-bff:3003/v1/teacher/graphql (404) | → teacher-bff:3003/graphql ✓ |
+| /api/v1/student/graphql | → student-bff:3009/v1/student/graphql (404) | → student-bff:3009/graphql ✓ |
+| /api/v1/parent/graphql  | → parent-bff:3010/v1/parent/graphql (404)   | → parent-bff:3010/graphql ✓  |
+
+**契约依据**：student-portal_contract.md §2.3「/api/v1/student/* → student-bff:3009/*」
+
+### 2.3 Docker 构建修复（已解决）
+
+**问题**：原 Dockerfile 使用 golang:1.22-alpine 且构建上下文为 service 目录，无法解析 shared-go 依赖（go.work 模式）。
+
+**修复**：
+
+- 升级基础镜像为 golang:1.25-alpine（匹配 go.work 的 go 1.25.0）
+- 构建上下文改为仓库根目录（访问 packages/shared-go）
+- 生成精简版 go.work（仅含 api-gateway + shared-go，排除 push-gateway）
+- 设置 GOPROXY=https://goproxy.cn,direct（国内网络环境）
