refactor: 迁移脚本系统重构 + 新增 db 脚本 + 工作日志

- 清理全部旧迁移文件(0000-0011)和 meta 目录
- 使用 drizzle-kit generate 从 schema 重新生成单一迁移文件
  - 0000_perfect_pestilence.sql: 包含全部 49 张表
  - 修复 0011_ai_providers.sql 未在 journal 注册导致 migrate 失败的问题
  - 修复缺少 snapshot 文件的问题
  - 移除复杂 PREPARE/EXECUTE 条件 SQL,使用标准 CREATE TABLE
- package.json 新增脚本:
  - db:create: 创建数据库
  - db:push: 直接同步 schema(开发用)
  - db:setup: 一键 create → migrate → seed
- 干净数据库全流程测试通过: create → migrate → seed
- 更新工作日志(docs/work_log.md)

 # Work Log
 
+## 2026-06-17
+
+### 1. Next.js 16 Proxy 修复
+- `src/proxy.ts` 导出函数从 `middleware` 重命名为 `proxy`（Next.js 16 要求）
+- 修复 `getToken()` 在 edge 运行时缺少 `secret` 导致的 `MissingSecret` 错误
+- 显式传入 `secret: process.env.NEXTAUTH_SECRET`
+- 主要修改：[proxy.ts](file:///e:/Desktop/CICD/src/proxy.ts)
+
+### 2. MySQL 端口切换 + 数据库创建脚本
+- `.env` 中 MySQL 端口从 13002 改为 14013
+- 新增 `scripts/create-db.ts`：连接 MySQL（不指定库）后执行 `CREATE DATABASE IF NOT EXISTS next_edu`，字符集 utf8mb4_unicode_ci
+- 主要修改：[.env](file:///e:/Desktop/CICD/.env)、[create-db.ts](file:///e:/Desktop/CICD/scripts/create-db.ts)
+
+### 3. 种子脚本完全重写（小学场景）
+- 完全重写 `scripts/seed.ts`，实现小学完整场景初始化
+- 数据规模：
+  - 1 所学校（实验小学）、2 个年级（一/二年级）、每年级 2 个班级
+  - 8 名教师（每班 2 名：1 班主任 + 1 科任，跨班覆盖语数外 3 科）
+  - 24 名学生（每班 6 名）+ 24 名家长
+  - 3 科教材（语数外各 1 本）+ 章节 + 知识点
+  - 15 道题目（每科 5 道：单选/文本/判断）
+  - 2 套试卷（语文/数学）+ 24 份提交 + 120 个答案
+  - 2 套作业 + 6 份提交 + 30 个答案
+  - 课表、成绩、考勤、课程计划、公告等完整数据
+  - 6 个角色 + 47 个权限点的 RBAC 映射（149 条记录）
+- 17 个顺序步骤，耗时约 127s
+- 主要修改：[seed.ts](file:///e:/Desktop/CICD/scripts/seed.ts)
+
+### 4. 迁移脚本系统重构
+- **问题**：旧迁移系统存在多个缺陷
+  - `0011_ai_providers.sql` 未在 `_journal.json` 中注册，导致 `drizzle-kit migrate` 失败
+  - 缺少多数 snapshot 文件（仅存 0008、0009）
+  - 迁移 SQL 使用复杂 PREPARE/EXECUTE 条件模式，维护困难
+- **修复**：清理全部旧迁移文件与 meta 目录，使用 `drizzle-kit generate` 从 schema 重新生成
+  - 生成单一迁移文件 `0000_perfect_pestilence.sql`，包含全部 49 张表
+  - journal 重置为单条记录，snapshot 完整
+- **新增 npm 脚本**（package.json）：
+  - `db:create`：创建数据库
+  - `db:push`：直接同步 schema（开发用）
+  - `db:setup`：一键 create → migrate → seed
+- 主要修改：[package.json](file:///e:/Desktop/CICD/package.json)、drizzle/ 目录
+
+### 5. 验证
+- 干净数据库全流程测试：`db:create` → `db:migrate` → `db:seed` 全部通过
+- 49 张表成功创建，种子数据完整写入
+- 测试账号（密码均为 123456）：
+  - 管理员: admin@xiaoxue.edu.cn
+  - 语文老师/一年级1班班主任: t_chinese_1@xiaoxue.edu.cn
+  - 数学老师: t_math_1@xiaoxue.edu.cn
+  - 英语老师: t_english_1@xiaoxue.edu.cn
+  - 学生: student_g1c1_1@xiaoxue.edu.cn
+  - 家长: parent_g1c1_1@xiaoxue.edu.cn
