+# shared-contracts 共享 crate 说明
+
+日期：`2026-04-21`
+
+## 1. crate 职责
+
+`shared-contracts` 是前后端兼容 contract 共享 crate，后续负责：
+
+1. HTTP 请求与响应 DTO
+2. SSE 事件结构与事件名约定
+3. response envelope、错误结构、兼容头部契约
+4. 各模块对外暴露的共享协议类型
+
+## 2. 当前阶段说明
+
+当前阶段已完成 Stage1 最小真实落地：
+
+1. 统一 response envelope / 头部常量
+2. `auth/login-options`
+3. `auth/me`
+4. `auth/sessions`
+5. `runtime/settings`
+
+当前阶段继续补齐的 Stage2 鉴权 DTO：
+
+1. `auth/entry`
+2. `auth/refresh`
+3. `auth/logout`
+4. `auth/logout-all`
+5. `auth/phone/send-code`
+6. `auth/phone/login`
+7. `auth/wechat/start`
+8. `auth/wechat/callback`
+9. `auth/wechat/bind-phone`
+
+当前阶段继续补齐的 Stage3 公开请求 DTO：
+
+1. `assets/direct-upload-tickets`
+2. `assets/read-url`
+3. `assets/objects/confirm`
+4. `assets/objects/bind`
+5. `story-sessions/begin`
+6. `story-sessions/continue`
+
+当前阶段继续补齐的 Stage4 显式成功响应 DTO：
+
+1. `assets/direct-upload-tickets`
+2. `assets/read-url`
+3. `assets/objects/confirm`
+4. `assets/objects/bind`
+5. `story-sessions/begin`
+6. `story-sessions/continue`
+
+当前阶段新增 Stage6 `character visual` 兼容 DTO：
+
+1. `assets/character-visual/generate`
+2. `assets/character-visual/jobs/:taskId`
+3. `assets/character-visual/publish`
+
+当前阶段新增 Stage7 `character animation` 模板与导入兼容 DTO：
+
+1. `assets/character-animation/templates`
+2. `assets/character-animation/import-video`
+
+当前阶段新增 Stage8 `character workflow cache` 第一批兼容 DTO：
+
+1. `assets/character-workflow-cache`
+2. `assets/character-workflow-cache/:characterId`
+
+当前阶段新增 Stage9 `character animation` 主链兼容 DTO：
+
+1. `assets/character-animation/generate`
+2. `assets/character-animation/jobs/:taskId`
+3. `assets/character-animation/publish`
+
+当前阶段新增 Stage5 `runtime story` 兼容桥 DTO 基线：
+
+1. `runtime/story/state/resolve` 请求 DTO
+2. `runtime/story/actions/resolve`、`runtime/story/initial`、`runtime/story/continue` 请求 DTO
+2. `RuntimeStoryActionResponse` 兼容响应 DTO
+3. `RuntimeStoryViewModel / presentation / patches / snapshot` 显式结构
+4. `RuntimeStoryAiResponse` 兼容响应 DTO
+
+当前仍刻意未做：
+
+1. SSE 事件结构
+2. 自动代码生成或跨语言 contract 同步
+3. 其他尚未收口模块的 handler 响应体显式 DTO 化
+
+## 3. 边界约束
+
+1. `shared-contracts` 只放协议类型与兼容结构，不承接业务规则、供应商适配或状态写入逻辑。
+2. 各模块 crate 对外暴露的协议优先复用这里的共享定义，避免重复散落。
+3. 前端兼容契约一旦进入本 crate，就必须与任务清单和基线文档同步维护。
