# module-auth 独立模块 crate 占位说明

日期：`2026-04-20`

## 1. crate 职责

`module-auth` 是鉴权与会话模块 crate，后续负责：

1. 用户身份、会话、风控、审计相关领域模型
2. 手机验证码、微信登录、密码登录的模块内用例编排
3. 与 `crates/api-server` 的鉴权接口装配对接
4. 与 `crates/spacetime-module` 的身份表、会话表聚合对接

## 2. 当前阶段说明

当前阶段已冻结前七张鉴权基础表设计，剩余重点收口在 JWT claims、refresh cookie 与旧接口兼容细节。

后续与本 crate 直接相关的任务包括：

1. 设计 `user_account`、`auth_identity`、`refresh_session`
2. 设计 `auth_audit_log`、`auth_risk_block`
3. 设计 `sms_auth_event`、`wechat_auth_state`
4. 落地 JWT claims、refresh cookie 与旧接口兼容

## 3. 边界约束

1. `module-auth` 负责鉴权领域规则与模块级编排，不直接把供应商 SDK 逻辑写进主工程。
2. 短信、微信、JWT、Cookie 等平台适配优先通过 `crates/platform-auth` 承接。
3. 身份与会话状态最终由 `crates/spacetime-module` 聚合，前端接口由 `crates/api-server` 暴露。
