# IAM 一期交付说明 / IAM Phase 1 Delivery

## 数据库归属 / Database ownership

全部表位于 `baiyue_iam`，由 `iam-service` 独占连接。`auth-service` 只访问 `baiyue_auth.auth_account` 与 `auth_refresh_token`。`iam_user.auth_user_id` 是跨库逻辑 ID，禁止建立跨库外键。商户数据通过 `tenant_id` 强制隔离；平台租户使用 `tenant_id=0`，权限通过 `app_code=PLATFORM`，商户端使用 `app_code=MERCHANT`。

All tables belong to `baiyue_iam`, accessed only by `iam-service`. `auth-service` owns credentials and tokens in `baiyue_auth`. `iam_user.auth_user_id` is a logical cross-database reference; no cross-database foreign keys are used. Every merchant query must constrain `tenant_id`. Platform scope uses `tenant_id=0` and `app_code=PLATFORM`; merchant scope uses `app_code=MERCHANT`.

## 代码落位 / Code placement

将 `src/main/java` 下的包合并到 `D:/baiyue/iam/src/main/java`；SQL 执行 `db/baiyue_iam.sql`。代码基于 Java 17、Spring Boot 3.2、MyBatis-Plus 3.5.7，并返回现有 `ApiResponse`。

Merge the packages under `src/main/java` into `D:/baiyue/iam/src/main/java`; execute `db/baiyue_iam.sql`. The skeleton targets Java 17, Spring Boot 3.2 and MyBatis-Plus 3.5.7, returning the existing `ApiResponse` envelope.
