+# Note 模块接口文档
+
+## 1. 模块说明
+
+`note` 是独立于现有 `app/api` 业务的笔记小程序模块，代码位置如下：
+
+- [app/note/controller](/root/work/tp/app/note/controller)
+- [app/note/service](/root/work/tp/app/note/service)
+- [app/note/model](/root/work/tp/app/note/model)
+
+当前已实现能力：
+
+1. 微信小程序登录
+2. 笔记创建、列表、详情、更新、删除
+3. 实时转写文本保存
+4. AI 总结生成与查询
+
+路由注册位置：
+
+- [route/app.php](/root/work/tp/route/app.php)
+
+---
+
+## 2. 鉴权说明
+
+除登录接口外，其余 `note` 接口都需要携带 JWT：
+
+- Header: `Authorization: Bearer {token}`
+
+`note` 模块复用现有 JWT 机制，但要求 token 载荷中必须包含：
+
+```json
+{
+  "userid": 123,
+  "guard": "note"
+}
+```
+
+说明：
+
+- `userid` 对应 `note_user.id`
+- `guard=note` 用于和旧 `api` 模块登录态隔离
+
+---
+
+## 3. 环境变量
+
+微信登录依赖以下配置：
+
+- `WECHAT_MINI_APPID`
+- `WECHAT_MINI_SECRET`
+- `DB_NOTE_HOSTNAME`
+- `DB_NOTE_DATABASE`
+- `DB_NOTE_USERNAME`
+- `DB_NOTE_PASSWORD`
+- `DB_NOTE_HOSTPORT`
+
+示例位置：
+
+- [\.example.env](/root/work/tp/.example.env)
+
+---
+
+## 4. 数据表
+
+表结构定义位置：
+
+- [database.sql](/root/work/tp/database.sql#L26)
+
+当前 `note` 模块使用以下 4 张表：
+
+1. `note_user`
+   用于小程序用户登录和用户资料
+
+2. `note_item`
+   笔记主表，包含正文、转写累计文本、状态、录音时长等
+
+3. `note_transcript`
+   实时转写分片记录表
+
+4. `note_ai_summary`
+   AI 总结结果表
+
+---
+
+## 5. 接口列表
+
+### 5.1 获取模块概览
+
+- 方法：`GET`
+- 路径：`/note/v1/meta/interfaces`
+- 是否鉴权：否
+
+用途：
+
+- 返回 note 模块接口规划概览
+
+---
+
+### 5.2 微信小程序登录
+
+- 方法：`POST`

+- 是否鉴权：否
+
+请求参数：
+
+| 字段 | 类型 | 必填 | 说明 |
+| :--- | :--- | :--- | :--- |
+| `code` | string | 是 | `wx.login` 获取的临时 code |
+| `nickname` | string | 否 | 用户昵称 |
+| `avatar_url` | string | 否 | 用户头像地址 |
+
+请求示例：
+
+```json
+{
+  "code": "021xxx",
+  "nickname": "张三",

+  "time": 1710000500
+}
+```
+
+说明：
+
+- 当前实现为规则版总结，不依赖外部大模型
+- 若已存在成功总结且 `force_refresh=0`，会直接返回已有结果
+
+---
+
+### 5.11 查看 AI 总结
+
+- 方法：`GET`
+- 路径：`/note/v1/ai/summary/:id`
+- 是否鉴权：是
+
+说明：
+
+- 返回指定笔记最新的一条总结记录
+
+---
+
+## 6. 错误码约定
+
+当前模块沿用项目统一返回结构：
+
+```json
+{
+  "code": 400,
+  "msg": "错误信息",
+  "data": [],
+  "time": 1710000000
+}
+```
+
+常见情况：
+
+- `400`：参数错误
+- `401`：未登录或登录态无效
+- `403`：用户被禁用
+- `404`：资源不存在
+- `500`：服务端错误
+- `502`：调用微信接口失败
+
+---
+
+## 7. 调用顺序建议
+
+小程序端推荐按以下顺序接入：
+
+1. 调 `wx.login`
+2. 把 `code` 发给 `POST /note/v1/auth/wechat-login`
+3. 保存返回的 `token`
+4. 创建笔记 `POST /note/v1/item/create`
+5. 录音转写过程中持续调用 `POST /note/v1/item/transcript/:id`
+6. 需要生成总结时调用 `POST /note/v1/ai/summary/:id`
+7. 打开详情页时调用 `GET /note/v1/item/:id`
+
+---
+
+## 8. 当前限制
+
+1. AI 总结目前是规则版，不是大模型版
+2. 微信登录依赖服务端已正确配置 `WECHAT_MINI_APPID` 和 `WECHAT_MINI_SECRET`
+3. 当前未实现文件音频上传，只实现了“转写文本写回后端”的数据链路
