-- 开发环境初始化脚本
--
-- 执行时机：docker-entrypoint-initdb.d —— **仅在 MySQL 数据卷为空时的首次启动执行**
-- 数据卷已存在时修改本文件不会生效，需要：
--   docker compose -f docker/docker-compose.dev.yml down -v && up -d
--
-- 内容 = V1 迁移的完整结构（额外带 DROP，开发环境允许重置）
-- 与 db/migration/V1__init_rbac_and_login_logs.sql 必须保持一致，
-- 由 backend/tests/integration/test_schema_sync.py 自动校验，防止两份 DDL 漂移
--
-- 结尾写入 alembic_version 记录，使 `alembic upgrade head` 在本库上成为空操作
