+# `/api/auth/me` 查询落地设计
+
+日期：`2026-04-21`
+
+## 1. 文档目的
+
+这份文档用于指导 `M2` 中 `实现 me 查询` 任务的首版落地，冻结：
+
+1. `GET /api/auth/me` 的请求与响应 contract。
+2. 当前阶段 Bearer JWT 与用户快照读取的衔接方式。
+3. `availableLoginMethods` 的返回口径。
+4. JWT 有效但本地用户不存在时的错误处理语义。
+
+## 2. 当前基线
+
+当前 Node `/api/auth/me` 具备以下最小语义：
+
+1. 必须先通过 Bearer JWT 校验。
+2. 用 `sub = user_id` 读取当前用户。
+3. 返回 `user + availableLoginMethods`。
+4. `availableLoginMethods` 只返回当前对外开启的补充登录方式，不包含 `password`。
+
+Rust 首版需要保留这条最小 contract，但当前阶段允许继续使用进程内仓储承接用户真相。
+
+## 3. 当前阶段范围
+
+本阶段只落以下内容：
+
+1. `module-auth` 增加按 `user_id` 查询当前用户能力。
+2. `api-server` 暴露 `GET /api/auth/me`。
+3. 返回与当前前端兼容的 `user + availableLoginMethods`。
+
+本阶段不包含：
+
+1. `refresh token` 轮换。
+2. 会话列表、审计、风控等扩展信息。
+3. `SpacetimeDB` 真正的身份表读取。
+
+## 4. contract
+
+### 4.1 请求
+
+1. 方法：`GET`
+2. 路径：`/api/auth/me`
+3. 鉴权：`Authorization: Bearer <token>`
+
+### 4.2 成功响应
+
+```json
+{
+  "user": {
+    "id": "user_00000001",
+    "username": "guest_001",
+    "displayName": "guest_001",
+    "phoneNumberMasked": null,
+    "loginMethod": "password",
+    "bindingStatus": "active",
+    "wechatBound": false
+  },
+  "availableLoginMethods": []
+}
+```
+
+说明：
+
+1. 当前阶段 `user` 字段固定返回当前登录用户快照，不返回 `null`。
+2. `availableLoginMethods` 只按当前对外配置返回：
+   - `SMS_AUTH_ENABLED=true` 时包含 `phone`
+   - `WECHAT_AUTH_ENABLED=true` 时包含 `wechat`
+3. `password` 不进入 `availableLoginMethods`，保持和 Node 现状一致。
+
+## 5. 错误语义
+
+### 5.1 缺少或非法 Bearer token
+
+1. 返回 `401 UNAUTHORIZED`
+
+### 5.2 JWT 有效但用户不存在
+
+1. 返回 `401 UNAUTHORIZED`
+2. 语义视为“当前登录态已失效，需要重新登录”
+
+说明：
+
+1. 当前阶段不把这种情况返回为 `404`。
+2. 这样可以与后续 `token_version`、会话吊销和用户禁用策略保持同一类恢复路径。
+
+## 6. crate 边界
+
+### 6.1 `module-auth`
+
+负责：
+
+1. 提供按 `user_id` 查询当前用户快照的能力。
+2. 继续复用密码登录阶段已经建立的同一份进程内用户真相。
+
+### 6.2 `api-server`
+
+负责：
+
+1. 复用现有 Bearer JWT 中间件拿到 `sub`。
+2. 调用 `module-auth` 查询用户。
+3. 组装 `AuthMeResponse`。
+
+## 7. 测试策略
+
+至少覆盖：
+
+1. 已登录用户可通过 `/api/auth/me` 取回当前用户。
+2. 当短信/微信开关开启时，`availableLoginMethods` 返回对应值。
+3. JWT 有效但用户不存在时返回 `401`。
+
+## 8. 后续衔接
+
+这条任务完成后，下一步顺序固定为：
+
+1. refresh token 轮换
+2. 会话吊销
+3. 手机验证码登录
+
+微信登录继续按“暂缓执行”处理。

+# `/api/auth/refresh` 轮换落地设计
+
+日期：`2026-04-21`
+
+## 1. 文档目的
+
+这份文档用于指导 `M2` 中 `实现 refresh token 轮换` 任务的首版落地，冻结：
+
+1. `POST /api/auth/refresh` 的请求与响应 contract。
+2. refresh cookie、服务端 refresh session 与 access token 三者的职责边界。
+3. “会话 ID 稳定、refresh token 可轮换”的固定语义。
+4. Rust 首版在未切入 SpacetimeDB 前的临时进程内实现方式。
+
+## 2. 当前基线
+
+当前 Node `/api/auth/refresh` 已具备以下稳定语义：
+
+1. 从 HttpOnly cookie 中读取原始 refresh token。
+2. 服务端只按 `refresh_token_hash` 查找当前活跃会话。
+3. refresh 成功后，不新建第二条会话，而是在原会话上轮换 refresh token。
+4. 轮换时会更新 `expires_at` 与 `last_seen_at`。
+5. 成功后返回新的 access token，并写回新的 refresh cookie。
+6. 失败时会主动清空 refresh cookie，要求前端重新登录。
+
+Rust 首版必须保留以上语义。
+
+## 3. 当前阶段范围
+
+本阶段只落以下内容：
+
+1. `module-auth` 增加进程内 refresh session 真相与轮换服务。
+2. `api-server` 暴露 `POST /api/auth/refresh`。
+3. 登录成功时创建 refresh session。
+4. refresh 成功时在原 session 上轮换 refresh token。
+5. access token 的 `sid` 固定改为稳定 `session_id`，不再直接复用 refresh token。
+
+本阶段不包含：
+
+1. `/api/auth/logout`
+2. `/api/auth/logout-all`
+3. `/api/auth/sessions`
+4. `/api/auth/sessions/:sessionId/revoke`
+5. SpacetimeDB reducer 真正写表
+
+## 4. contract
+
+### 4.1 请求
+
+1. 方法：`POST`
+2. 路径：`/api/auth/refresh`
+3. 请求体：空
+4. 鉴权来源：refresh cookie
+
+### 4.2 成功响应
+
+```json
+{
+  "token": "<access-token>"
+}
+```
+
+同时响应头必须写回新的 refresh cookie。
+
+### 4.3 失败响应
+
+当 refresh token 缺失、会话不存在、会话已过期或用户不存在时：
+
+1. 返回 `401 UNAUTHORIZED`
+2. 同时清理 refresh cookie
+
+## 5. 固定语义
+
+### 5.1 session_id 与 refresh token 必须拆开
+
+从本任务开始固定以下规则：
+
+1. `session_id` 是稳定会话主键。
+2. refresh token 是可轮换的会话凭证。
+3. access token 的 `sid` 必须写入 `session_id`。
+4. refresh 轮换只更新 refresh token，不更改 `session_id`。
+
+禁止继续把 refresh token 直接塞进 JWT `sid`。
+
+### 5.2 refresh 是“原会话轮换”
+
+refresh 成功后：
+
+1. 保留原 `session_id`
+2. 生成新的原始 refresh token
+3. 用新的 `refresh_token_hash` 覆盖旧值
+4. 更新 `expires_at`
+5. 更新 `last_seen_at`
+
+不允许新建第二条 session。
+
+## 6. crate 边界
+
+### 6.1 `module-auth`
+
+负责：
+
+1. 管理 refresh session 进程内真相。
+2. 提供创建 refresh session 与轮换 refresh session 的用例。
+3. 提供按 `user_id` 查询用户快照的能力，供 refresh 成功后重新签发 access token。
+
+不负责：
+
+1. 生成原始 refresh token。
+2. 读写 cookie。
+3. 签发 JWT。
+
+### 6.2 `platform-auth`
+
+负责：
+
+1. 生成原始 refresh token。
+2. 对 refresh token 做哈希。
+3. 构造 refresh cookie 的 `Set-Cookie` 头。
+4. 从 cookie header 中读取 refresh token。
+
+### 6.3 `api-server`
+
+负责：
+
+1. 从请求 cookie 中提取 refresh token。
+2. 调用 `module-auth` 执行 refresh session 轮换。
+3. 根据用户快照与稳定 `session_id` 重新签发 access token。
+4. refresh 失败时清理 cookie。
+
+## 7. 进程内存储模型
+
+当前阶段 `module-auth` 继续使用进程内内存仓储承接 refresh session，字段至少包括：
+
+1. `session_id`
+2. `user_id`
+3. `refresh_token_hash`
+4. `issued_by_provider`
+5. `expires_at`
+6. `created_at`
+7. `updated_at`
+8. `last_seen_at`
+9. `revoked_at`
+
+说明：
+
+1. 这只是 SpacetimeDB 正式落地前的阶段性实现。
+2. 字段命名与语义继续对齐 [SPACETIMEDB_REFRESH_SESSION_TABLE_DESIGN_2026-04-21.md](./SPACETIMEDB_REFRESH_SESSION_TABLE_DESIGN_2026-04-21.md)。
+
+## 8. 流程
+
+### 8.1 登录创建 session
+
+密码登录成功后：
+
+1. `api-server` 生成原始 refresh token。
+2. `api-server` 计算 `refresh_token_hash`。
+3. `module-auth` 创建一条新 session，并返回稳定 `session_id`。
+4. `api-server` 用该 `session_id` 写入 access token 的 `sid`。
+5. `api-server` 把原始 refresh token 写回 cookie。
+
+### 8.2 refresh 轮换 session
+
+当请求 `POST /api/auth/refresh` 时：
+
+1. 从 cookie 中读取原始 refresh token。
+2. 计算 `refresh_token_hash`。
+3. `module-auth` 查找当前活跃 session。
+4. 校验 `expires_at > now` 且 `revoked_at == null`。
+5. 读取该 session 对应用户。
+6. 生成新的原始 refresh token。
+7. 用新 hash 更新同一条 session。
+8. 返回新的 access token 与新的 refresh cookie。
+
+## 9. 错误语义
+
+以下情况统一返回 `401`：
+
+1. 缺少 refresh cookie
+2. refresh token 命中不到 session
+3. refresh session 已过期
+4. refresh session 已吊销
+5. session 对应用户不存在
+
+错误文案统一保持中文，并沿用“当前登录态已失效，请重新登录”这类恢复导向语义。
+
+## 10. 测试策略
+
+至少覆盖：
+
+1. 登录成功后可用 cookie 调用 `/api/auth/refresh`
+2. refresh 成功会写回新的 cookie
+3. refresh 成功返回新的 access token
+4. refresh 后旧 refresh token 立即失效
+5. 缺少 cookie 时返回 `401`
+6. 无效 refresh token 时返回 `401` 且清理 cookie
+
+## 11. 完成定义
+
+满足以下条件时，本任务视为完成：
+
+1. Rust 侧已提供 `POST /api/auth/refresh`。
+2. access token `sid` 已改为稳定 `session_id`。
+3. refresh token 轮换成功时不创建新会话。
+4. refresh 失败时会清理 cookie。
+5. 文档、任务清单与测试已同步更新。

+# 密码登录与自动建号落地设计
+
+日期：`2026-04-21`
+
+## 1. 文档目的
+
+这份文档用于指导 `M2` 中以下两条任务的首版落地：
+
+1. `实现密码登录`
+2. `实现账号自动创建 / 幂等登录兼容策略`
+
+目标是先把当前 Node 已经稳定运行的 `/api/auth/entry` 语义迁到 Rust 工作区，并冻结：
+
+1. `api-server` 对外暴露的最小兼容接口。
+2. `module-auth` 负责的密码登录用例边界。
+3. 自动建号与并发幂等兼容规则。
+4. 登录成功后与 JWT、refresh cookie 的衔接方式。
+
+## 2. 当前基线
+
+当前 Node `/api/auth/entry` 主链已经具备如下语义：
+
+1. 输入 `username + password`。
+2. 若用户名不存在，则自动创建一个本地账号。
+3. 若用户名已存在，则校验密码。
+4. 登录成功后签发 access token。
+5. 同时创建 refresh session，并把原始 refresh token 写入 HttpOnly cookie。
+6. 并发创建同一用户名时，后到的请求会回退为“查已存在账号并校验密码”，不因唯一键冲突直接失败。
+
+这条链路既是当前前端匿名/游客恢复的基础，也是真实 `/api/auth/entry` contract 的既有事实，因此 Rust 首版必须兼容。
+
+## 3. 设计输入
+
+本任务直接受以下文档约束：
+
+1. [SPACETIMEDB_AUTH_USER_ACCOUNT_TABLE_DESIGN_2026-04-21.md](./SPACETIMEDB_AUTH_USER_ACCOUNT_TABLE_DESIGN_2026-04-21.md)
+2. [SPACETIMEDB_AUTH_IDENTITY_TABLE_DESIGN_2026-04-21.md](./SPACETIMEDB_AUTH_IDENTITY_TABLE_DESIGN_2026-04-21.md)
+3. [OIDC_JWT_CLAIMS_DESIGN_2026-04-21.md](./OIDC_JWT_CLAIMS_DESIGN_2026-04-21.md)
+4. [PLATFORM_AUTH_JWT_ADAPTER_DESIGN_2026-04-21.md](./PLATFORM_AUTH_JWT_ADAPTER_DESIGN_2026-04-21.md)
+5. [PLATFORM_AUTH_REFRESH_COOKIE_ADAPTER_DESIGN_2026-04-21.md](./PLATFORM_AUTH_REFRESH_COOKIE_ADAPTER_DESIGN_2026-04-21.md)
+
+关键冻结点：
+
+1. `password_hash` 当前继续由 `user_account` 承担，不进入 `auth_identity`。
+2. `sub` 必须是稳定 `user_id`。
+3. 登录成功后必须继续同时生成 access token 和 refresh session。
+4. 自动建号兼容必须保留，不能因为迁到 Rust 就删除。
+
+## 4. 首版落地范围
+
+本阶段只落以下内容：
+
+1. `module-auth` 中的密码登录用例。
+2. `api-server` 中的 `POST /api/auth/entry`。
+3. 用户名校验、密码哈希校验与自动建号。
+4. 登录成功后的 access token 与 refresh cookie 主链打通。
+
+本阶段明确不包含：
+
+1. SpacetimeDB 真正的 `user_account` / `refresh_session` reducer 写入。
+2. `/api/auth/me`、`/api/auth/logout`、`/api/auth/refresh` 的正式业务闭环。
+3. 手机验证码与微信登录链路。
+
+## 5. crate 边界
+
+### 5.1 `module-auth`
+
+负责：
+
+1. 用户名与密码的领域校验。
+2. 密码登录主用例。
+3. 自动建号与并发幂等兼容策略。
+4. 输出登录成功所需的最小用户快照。
+
+不负责：
+
+1. JWT 编解码。
+2. refresh cookie 解析与写回。
+3. HTTP 请求解析与响应拼装。
+
+### 5.2 `platform-auth`
+
+负责：
+
+1. 密码哈希与校验适配。
+2. JWT 签发与校验。
+3. refresh cookie 读写适配。
+
+不负责：
+
+1. 决定账号是否应当自动创建。
+2. 决定用户状态是否合法。
+
+### 5.3 `api-server`
+
+负责：
+
+1. 解析 `POST /api/auth/entry` 请求体。
+2. 调用 `module-auth` 用例。
+3. 调用 `platform-auth` 签发 token 和 refresh cookie。
+4. 返回与旧接口兼容的 JSON body。
+
+## 6. 请求与响应 contract
+
+### 6.1 请求体
+
+固定沿用当前 contract：
+
+```json
+{
+  "username": "guest_001",
+  "password": "secret123"
+}
+```
+
+### 6.2 成功响应
+
+固定沿用当前 contract：
+
+```json
+{
+  "token": "<access-token>",
+  "user": {
+    "id": "user_xxx",
+    "username": "guest_001",
+    "displayName": "guest_001",
+    "phoneNumberMasked": null,
+    "loginMethod": "password",
+    "bindingStatus": "active",
+    "wechatBound": false
+  }
+}
+```
+
+同时响应头必须写回 refresh cookie。
+
+## 7. 用户名与密码规则
+
+当前阶段继续对齐 Node 基线：
+
+1. `username` 只允许 `3` 到 `24` 位字母、数字、下划线。
+2. `password` 长度必须在 `6` 到 `128` 位之间。
+
+任一校验失败时：
+
+1. 返回 `400 BAD_REQUEST`
+2. 错误文案继续保持中文
+
+## 8. 自动建号与幂等兼容
+
+### 8.1 自动建号
+
+当 `username` 不存在时：
+
+1. 用当前请求里的 `password` 生成密码哈希。
+2. 创建一条本地账号。
+3. `display_name = username`
+4. `login_provider = password`
+5. `account_status = active`
+6. `token_version = 1`
+
+### 8.2 已存在账号
+
+当 `username` 已存在时：
+
+1. 校验密码哈希。
+2. 校验失败返回 `401 UNAUTHORIZED`。
+3. 校验成功继续登录。
+
+### 8.3 并发幂等兼容
+
+若两个请求并发创建同一用户名：
+
+1. 允许其中一个请求先创建成功。
+2. 后一个请求若命中唯一键冲突，不直接失败。
+3. 后一个请求必须重新查询该用户名。
+4. 若查到账号，则按“已存在账号”路径继续校验密码。
+
+这保证了当前前端重复调用 `/api/auth/entry` 时可以恢复同一账号，而不是随机失败。
+
+## 9. 首版存储策略
+
+当前阶段为了先跑通工程闭环，固定采用：
+
+1. `module-auth` 内的进程内内存仓储适配器作为临时真相。
+
+说明：
+
+1. 这是阶段性工程策略，不改变最终 `SpacetimeDB` 作为真相源的目标。
+2. 当前这样做是为了先把 crate 边界、用例形状、HTTP contract、JWT / refresh cookie 主链稳定下来。
+3. 后续切到 `SpacetimeDB` 时，应保持 `module-auth` 用例接口不变，只替换仓储实现。
+
+## 10. 密码哈希策略
+
+当前阶段继续对齐 Node：
+
+1. `Argon2id`
+
+说明：
+
+1. Rust 侧不再复用 Node 原生库，但哈希语义继续保持同类算法。
+2. 当前目标是“工程能力闭环”，不是做跨语言哈希值兼容迁移。
+3. 若未来需要与 Node 历史哈希共存，需单独补兼容文档和迁移策略。
+
+## 11. 与 JWT / refresh cookie 的衔接
+
+密码登录成功后：
+
+1. `module-auth` 返回最小用户领域对象。
+2. `api-server` 基于该对象构造 `AccessTokenClaimsInput`。
+3. `platform-auth` 签发 access token。
+4. `platform-auth` 生成 refresh token 与 `Set-Cookie` 头。
+5. `api-server` 返回 `token + user`。
+
+当前阶段固定 claims 值：
+
+1. `provider = password`
+2. `roles = ["user"]`
+3. `binding_status = active`
+4. `phone_verified = false`
+5. `display_name = username`
+
+## 12. 测试策略
+
+当前阶段至少覆盖：
+
+1. 首次密码登录自动建号成功。
+2. 同用户名同密码可重复登录同一账号。
+3. 同用户名不同密码返回 `401`。
+4. 非法用户名返回 `400`。
+5. 登录成功时返回 access token。
+6. 登录成功时写回 refresh cookie。
+
+## 13. 完成定义
+
+满足以下条件时，本任务视为完成：
+
+1. `module-auth` 不再只是 README，占位被真实 crate 实现替换。
+2. `POST /api/auth/entry` 可在 Rust 侧独立跑通。
+3. 自动建号与幂等兼容行为可验证。
+4. JWT 与 refresh cookie 登录成功主链打通。
+5. 文档、任务清单与测试同步完成。
+
+## 14. 后续衔接
+
+这条任务完成后，下一步顺序固定为：
+
+1. `me` 查询
+2. refresh token 轮换
+3. 会话吊销
+4. 手机验证码登录
+
+微信登录继续按“暂缓执行”处理，直到用户重新解锁。

 ## 2. 当前阶段说明

-当前提交仅完成目录占位，不提前进入 OSS SDK、上传策略与对象读写实现。
+当前提交已落地最小可用 OSS 基础设施：

-后续与本 package 直接相关的任务包括：
+1. `PostObject` 浏览器直传签名
+2. 旧 `/generated-*` 公开前缀到 OSS `object_key` 的兼容映射
+3. `object_key -> publicUrl` 解析
+4. `x-oss-meta-*` 元数据归一化与大小限制校验
+5. `content-type`、`content-length-range`、`success_action_status` policy 条件生成

-1. 落地 `PostObject`、STS、服务端上传适配
-2. 落地对象确认、签名 URL 与 CDN URL 解析适配
-3. 落地 `x-oss-meta-*` 元数据与对象标签适配
-4. 对齐旧 `/generated-*` 路径兼容策略
+当前仍未落地的内容：
+
+1. `STS` 临时授权
+2. 服务端上传 helper
+3. 私有对象签名 URL
+4. 对象确认与业务绑定

 ## 3. 边界约束
