+
+## 1. 本轮完成工作
+
+### 1.1 P3.14 考试实时事件（3 个新 RPC + 3 个新 Kafka 事件）
+
+下游 push-gateway / student-bff / student-portal 明确要求 core-edu 发布 3 类考试实时事件，用于 WebSocket 推送。本轮已完成实现：
+
+| RPC                                | 触发场景         | Kafka 事件                | Topic                                  |
+| ---------------------------------- | ---------------- | ------------------------- | -------------------------------------- |
+| `ExamService.ExtendExam`           | 教师延长考试时间 | `exam.extended`           | `edu.teaching.exam.extended`           |
+| `ExamService.ForceSubmitExam`      | 教师强制收卷     | `exam.force_submitted`    | `edu.teaching.exam.force_submitted`    |
+| `ExamService.ReorderExamQuestions` | 教师调整题目顺序 | `exam.question_reordered` | `edu.teaching.exam.question_reordered` |
+
+实现方式：
+
+- proto 契约：在 `core_edu.proto` ExamService 中新增 3 个 RPC + 对应 message
+- 服务层：[exams.service.ts](file:///e:/Desktop/Edu/services/core-edu/src/exams/exams.service.ts) 新增 `extendExam` / `forceSubmitExam` / `reorderExamQuestions` 方法
+- 事件发布：通过 Outbox 模式事务内写入 `core_edu_outbox` 表，OutboxPublisher 轮询投递到 Kafka
+- gRPC handler：[grpc.server.ts](file:///e:/Desktop/Edu/services/core-edu/src/grpc/grpc.server.ts) 注册 3 个新 handler
+- TOPIC_MAP：[outbox.publisher.ts](file:///e:/Desktop/Edu/services/core-edu/src/shared/outbox/outbox.publisher.ts) 新增 3 个事件类型映射
+
+### 1.2 修复 pino 导入错误
+
+[logger.ts](file:///e:/Desktop/Edu/services/core-edu/src/shared/observability/logger.ts) 从 `import pino from 'pino'` 改为 `import { pino } from 'pino'`，与其他服务一致。
+
+### 1.3 验证结果
+
+```
+镜像：edu/core-edu:test
+容器：edu-core-edu-test（DEV_MODE=true, HTTP 13004→3004 + gRPC 50053）
+smoke test：27/27 PASS（含 3 个 P3.14 新 RPC）
+```

+
+### 2.2 parent-bff 待澄清项（不需要 core-edu 新增 RPC）
+
+parent-bff nextstep-v2.md §6.3 列出 7 个"待补全"RPC，经核对全部可由现有 RPC 满足：
+
+| parent-bff 提议                                 | core-edu 现有实现                                                         | 澄清                                                              |
+| ----------------------------------------------- | ------------------------------------------------------------------------- | ----------------------------------------------------------------- |
+| `ClassService.GetClass`（ISSUE-008）            | ✅ `ClassService.GetClass`                                                | proto 已定义，已实现，ISSUE-008 已解决                            |
+| `AttendanceService.ListAttendance`              | ✅ `AttendanceService.ListAttendanceByClass` 或 `ListAttendanceByStudent` | parent-bff 按班级或按学生查询，两个 RPC 已实现                    |
+| `ExamResultService.GetExamResult`（新 Service） | ✅ `ExamService.GetExam` + `GradeService.ListGradesByExam` 组合           | 不需要新 Service，考试结果 = 考试详情 + 成绩列表                  |
+| `ReportCardService.GetReportCard`（新 Service） | ✅ `GradeService.GetReportCard`                                           | 不需要新 Service，已在 GradeService 中实现                        |
+| `LeaveRequestService.List/Create`               | ✅ `ListLeaveRequestsByStudent` + `CreateLeaveRequest`                    | 家长视角通过 `studentId=childId` 参数实现                         |
+| `AcademicYearService.List`（新 Service）        | ✅ `AdminService.ListAcademicYears`                                       | 不需要新 Service，已在 AdminService 中实现                        |
+| `ExportService.ExportGrades`（新 Service）      | ✅ `GradeService.ListGradesByStudent`                                     | 导出属 BFF/Portal 层格式化能力，core-edu 提供数据，BFF 负责格式化 |
+
+**结论：core-edu 不需要新增任何 RPC 或 Service。** parent-bff 文档中提议的新 Service 均可由现有 9 Service / 43 RPC 组合满足。
+
+### 2.3 Kafka topic 名协调结论
+
+push-gateway 期望 topic `edu.notify.notification.sent`，student-bff/student-portal 期望 topic `edu.exam.events`。
+
+**协调结论：core-edu 遵循现有 `edu.teaching.exam.*` 命名规范，不改动。**
+
+正确的事件流：
+
+```
+core-edu → edu.teaching.exam.extended → msg 消费 → edu.notify.notification.sent → push-gateway → WebSocket
+```
+
+- core-edu 发布到 `edu.teaching.exam.*`（遵循 outbox.publisher.ts TOPIC_MAP 规范）
+- msg 服务负责消费 `edu.teaching.exam.*` 并转发到 `edu.notify.notification.*`
+- push-gateway 消费 `edu.notify.notification.*`
+- student-bff 应消费 `edu.teaching.exam.*`（而不是期望 core-edu 直接发布到 `edu.exam.events`）
+
+### 2.4 事件 payload 字段对齐（msg 服务需求）
+
+msg nextstep.md §6 要求 core-edu 发布的事件 payload 字段名与 msg consumer 对齐。core-edu 当前事件 payload 遵循 `event-builder.ts` 的标准格式：
+
+```json
+{
+  "event_id": "UUID",
+  "aggregate_id": "examId",
+  "event_type": "exam.extended",
+  "occurred_at": 1234567890,
+  "payload": {
+    "examId": "...",
+    "classId": "...",
+    "subjectId": "...",
+    "extensionSeconds": 300,
+    "newDuration": 7200
+  },
+  "metadata": {
+    "schema_version": "v1",
+    "trace_id": "...",
+    "user_id": "..."
+  }
+}
+```
+
+msg 服务需按此结构消费。字段名使用驼峰命名（与 events.proto ExamEvent message 的 snake_case 不同，因为 Outbox payload 是 JSON 序列化，不经过 proto 编码）。
