+## 1. 概述
+
+parent-bff 是家长端聚合层 BFF（Backend For Frontend），端口 3010，基于 NestJS + GraphQL Yoga。负责聚合 iam / core-edu / data-ana / msg 四个下游微服务的 gRPC 接口，为 parent-portal 前端提供场景化 GraphQL API。
+
+**路由路径（ARB-022 §24.4 ISSUE-003 方案 A 双 /v1 前缀）：**
+
+```
+parent-portal
+  → POST /api/v1/parent/v1/graphql        (前端调用路径)
+  → api-gateway registerBffProxy("parent") (剥离 /api/v1/parent)
+  → parent-bff:3010 /v1/graphql            (BFF 接收路径)
+  → GraphqlController @Controller("v1/graphql")
+```
+
+**本地 Docker 测试结果（2026-07-14，DEV_MODE=false，不使用 mock）：**
+
+- ✅ TypeScript 编译零错误（`tsc --noEmit -p tsconfig.test.json`）
+- ✅ ESLint 零错误（`eslint src test`）
+- ✅ 单元测试 + 集成测试全通过（128 tests, 13 test files）
+- ✅ Docker 镜像构建成功（`edu/parent-bff:test`）
+- ✅ 容器启动正常（端口 3010，DEV_MODE=false 生产模式）
+- ✅ `/healthz` 返回 200（liveness 通过）
+- ✅ `/readyz` 返回 200（status=degraded，下游 gRPC 不可达但 Redis up）
+- ✅ `/v1/graphql` GraphQL 查询正常响应（`{ __typename }` → `{ data: { __typename: "Query" } }`）
+- ✅ `/v1/graphql` 扩展查询正常（`{ myChildren { id } }` → `{ data: { myChildren: [] } }`）
+- ✅ `/v1/graphql` Mutation 正常（`mutation { markAllAsRead { count } }` → `{ data: { markAllAsRead: { count: 0 } } }`）
+- ✅ `/metrics` 返回 Prometheus 指标（graphql_requests_total + graphql_duration_seconds）
+- ✅ 优雅降级：下游 gRPC 不可达时 resolver 返回空数据而非崩溃

+| 6   | JSON scalar 支持                                                   | ✅   | `resolvers/index.ts` 新增 JSONScalar（用于 NotificationPreferences.preferences 等动态结构）             |
+| 7   | Response Mapper 更新                                               | ✅   | `mapParent` 增加 permissions/schoolId，新增 `mapChildBrief`                                             |

+
+### 2.2 关键修复详情
+
+**GraphQL 端点路径（ARB-022 §24.4 ISSUE-003 方案 A）：**
+
+| 文件                              | 路径配置                         |
+| --------------------------------- | -------------------------------- |
+| `src/entry/graphql.controller.ts` | `@Controller("v1/graphql")`      |
+| `src/graphql/yoga.ts`             | `graphqlEndpoint: "/v1/graphql"` |
+| `src/graphql/graphql.module.ts`   | `forRoutes("v1/graphql")`        |
+
+**Proto/Schema 路径解析（process.cwd() 方式）：**
+
+| 文件                               | 路径解析                                                                        |
+| ---------------------------------- | ------------------------------------------------------------------------------- |
+| `src/graphql/schema.ts`            | `process.cwd() + ../../packages/shared-ts/contracts/graphql/parent-bff.graphql` |
+| `src/clients/grpc/grpc.factory.ts` | `process.cwd() + ../../packages/shared-proto/proto`                             |
+
+**Dockerfile 关键修复：**
+
+- 构建上下文改为 repo root（访问 packages/shared-proto + packages/shared-ts）
+- 复制 `tsconfig.base.json`（`tsconfig.json` extends `../../tsconfig.base.json`）
+- runtime stage：`--ignore-workspace --ignore-scripts`（避免 workspace 解析 + 跳过 native 构建）
+- 运行时保留 `packages/shared-proto` + `packages/shared-ts` 目录结构

+## 3. 上游依赖（调用 parent-bff 的模块）
+
+### 3.1 api-gateway（ai01 负责）— P0

+| --- | ------------------------------------------ | ---------------------------------------------------------------------------------- | ---- |
+| 1   | `/api/v1/parent/*` 反向代理路由            | 前端请求经 api-gateway 代理到 parent-bff:3010                                      | ✅   |
+| 2   | `registerBffProxy("parent", ...)` 路径重写 | 剥离 `/api/v1/parent`，转发剩余路径（`/v1/graphql`）到 parent-bff                  | ✅   |
+| 3   | JWT 鉴权 + x-user-* 头注入                 | api-gateway 校验 JWT 后注入 `x-user-id`/`x-user-roles`/`x-data-scope`/`x-trace-id` | ✅   |
+| 4   | CORS 白名单                                | `CORS_ORIGINS` 环境变量配置                                                        | ✅   |
+| 5   | 限流（IP 级令牌桶）                        | 100 rps，突发 20                                                                   | ✅   |
+| 6   | 熔断（下游 5xx 触发）                      | `CircuitBreaker("downstream")`                                                     | ✅   |
+
+**验证要点：**
+
+- api-gateway 入站 `/api/v1/parent/v1/graphql` → 剥离 `/api/v1/parent` → 转发 `/v1/graphql` 到 parent-bff:3010
+- parent-bff GraphqlController 注册在 `/v1/graphql`，接收路径匹配
+- 经 api-gateway 代理访问 `http://api-gateway:8080/api/v1/parent/v1/graphql` 应返回 200

+| --- | -------------------------------------- | --------------------------------------------------- | ---- |
+| 1   | `NEXT_PUBLIC_GRAPHQL_ENDPOINT` 配置    | 前端 GraphQL 客户端调用 `/api/v1/parent/v1/graphql` | ✅   |
+| 2   | 32 个 Query + 6 个 Mutation operations | 前端定义的 GraphQL 操作，需 parent-bff schema 对齐  | ✅   |
+| 3   | Mock 数据禁用                          | `NEXT_PUBLIC_API_MOCKING=disabled`，使用真实后端    | ✅   |
+
+**前端调用路径：**
+
+```
+parent-portal → POST /api/v1/parent/v1/graphql
+  → api-gateway 剥离 /api/v1/parent
+  → parent-bff:3010/v1/graphql
+```

+## 5. Docker 本地测试
+
+### 5.1 镜像构建
+
+```bash
+# 在仓库根目录执行（需要访问 packages/shared-proto + packages/shared-ts + tsconfig.base.json）
+docker build -t edu/parent-bff:test -f services/parent-bff/Dockerfile .
+```
+
+### 5.2 容器启动
+
+```bash
+# 加入 edu-full_default 网络（与 Redis/MySQL/Kafka 等基础设施同网络）
+docker run -d \
+  --name edu-parent-bff-test \
+  --network edu-full_default \
+  -p 3010:3010 \
+  -e NODE_ENV=production \
+  -e DEV_MODE=false \
+  -e PORT=3010 \
+  -e REDIS_URL=redis://edu-redis:6379 \
+  -e IAM_GRPC_TARGET=iam:50052 \

+  -e CORS_ORIGINS=http://localhost:4002 \
+  -e GRAPHQL_INTROSPECTION_ENABLED=true \
+  edu/parent-bff:test
+```
+
+### 5.3 健康检查验证
+
+```bash
+# liveness（返回 200）
+curl http://localhost:3010/healthz
+# {"status":"ok","service":"parent-bff","timestamp":"..."}
+
+# readiness（返回 200，status=degraded 因为下游 gRPC 不可达）
+curl http://localhost:3010/readyz
+# {"status":"degraded","checks":{"iam":{"status":"down",...},"redis":{"status":"up",...}}}
+
+# Prometheus 指标
+curl http://localhost:3010/metrics
+```
+
+### 5.4 GraphQL 端点验证
+
+```bash
+# 必须携带 x-user-* 头（api-gateway 注入）
+curl -X POST http://localhost:3010/v1/graphql \
+  -H "Content-Type: application/json" \
+  -H "x-user-id: parent-001" \

+# {"data":{"__typename":"Query"}}
+
+# 扩展查询（优雅降级）
+curl -X POST http://localhost:3010/v1/graphql \

+  -H "x-user-id: parent-001" \
+  -H "x-user-roles: parent" \
+  -d '{"query":"{ myChildren { id name } }"}'
+# {"data":{"myChildren":[]}}
+
+# Mutation
+curl -X POST http://localhost:3010/v1/graphql \

+
+## 1. 概述
+
+parent-bff 是家长端聚合层 BFF（Backend For Frontend），端口 3010，基于 NestJS + GraphQL Yoga。负责聚合 iam / core-edu / data-ana / msg 四个下游微服务的 gRPC 接口，为 parent-portal 前端提供场景化 GraphQL API。
+
+**路由路径（ARB-022 §24.4 ISSUE-003 方案 A 双 /v1 前缀）：**
+
+```
+parent-portal
+  → POST /api/v1/parent/v1/graphql        (前端调用路径)
+  → api-gateway registerBffProxy("parent") (剥离 /api/v1/parent)
+  → parent-bff:3010 /v1/graphql            (BFF 接收路径)
+  → GraphqlController @Controller("v1/graphql")
+```
+
+**本地 Docker 测试结果（2026-07-13）：**
+
+- ✅ TypeScript 编译零错误（`tsc --noEmit -p tsconfig.test.json`）
+- ✅ ESLint 零错误（`eslint src test`）
+- ✅ 单元测试 + 集成测试全通过（128 tests, 13 test files）
+- ✅ Docker 镜像构建成功（`edu/parent-bff:test`）
+- ✅ 容器启动正常（端口 3010，DEV_MODE=false 生产模式）
+- ✅ `/healthz` 返回 200（liveness 通过）
+- ✅ `/readyz` 返回 200（status=degraded，下游 gRPC 不可达但 Redis up）
+- ✅ `/v1/graphql` GraphQL 查询正常响应（`{ __typename }` → `{ data: { __typename: "Query" } }`）
+- ✅ `/metrics` 返回 Prometheus 指标（graphql_requests_total + downstream_calls_total）
+- ✅ 优雅降级：下游 gRPC 不可达时 resolver 返回空数据而非崩溃（`{ children { id } }` → `{ data: { children: [] } }`）

+| `src/graphql/graphql.module.ts`   | `forRoutes("v1/graphql")`        |
+
+**Dockerfile 关键修复：**
+
+- builder stage：`pnpm install --no-frozen-lockfile --ignore-scripts`（跳过 husky prepare）
+- runtime stage：`pnpm install --prod --no-frozen-lockfile --ignore-workspace --ignore-scripts`（避免 workspace 解析 + 跳过 native 构建）
+- 运行时保留 `packages/shared-proto` + `packages/shared-ts` 目录结构（proto/schema 加载需要）

+
+**验证要点：**
+
+- api-gateway 入站 `/api/v1/parent/v1/graphql` → 剥离 `/api/v1/parent` → 转发 `/v1/graphql` 到 parent-bff:3010
+- parent-bff GraphqlController 注册在 `/v1/graphql`，接收路径匹配
+- 经 api-gateway 代理访问 `http://api-gateway:8080/api/v1/parent/v1/graphql` 应返回 200

+
+### 5.2 容器启动
+
+```bash
+# 加入 edu-full_default 网络（与 Redis/MySQL/Kafka 等基础设施同网络）
+docker run -d \
+  --name edu-parent-bff-test \
+  --network edu-full_default \
