+# KIOSK 工程业务与技术导读
+
+> 面向第一次接手工程的开发者。本文基于 2026-08-04 的代码状态整理，目标是先建立完整的业务和技术心智模型，再进入具体模块开发。
+
+## 1. 一句话理解这个工程
+
+KIOSK 是部署在景区或线下门店 Android 自助终端上的照片售卖与打印客户端：游客可以上传手机照片，或通过人脸识别找到景区相机拍摄的照片，完成选片和支付后，由终端连接 DNP 照片打印机出片。
+
+它同时还是一台长期在线的设备，因此还承担：
+
+- 设备身份认证和配置同步
+- WebSocket 实时消息接收与心跳上报
+- 微信扫码隐私取片任务
+- 打印机、纸张余量和任务状态管理
+- 待机海报、视频、直播和语音播放
+- 运营素材上传
+- APK 在线升级和开机自启动
+
+应用名称是“自助照片打印”，Application ID 为 `com.yzx.kiosk`，最低支持 Android 8.0（API 26）。
+
+## 2. 业务参与方
+
+理解下面几个参与方后，工程中的接口和状态会清晰很多。
+
+| 参与方 | 职责 |
+| --- | --- |
+| 游客 | 在终端上选业务、拍照识别人脸、选片、扫码支付和取走照片 |
+| 手机端/微信页面 | 扫终端二维码、上传照片、支付或发起隐私取片 |
+| KIOSK Android 客户端 | 展示业务页面，维护设备状态，接收订单并驱动打印机 |
+| Oscar 业务后端 | 下发设备配置、二维码、价格、订单、Socket Token、版本信息等 |
+| 照片盒子/人脸服务 | 保存景区相机照片，提供公网或局域网人脸检索及图片地址 |
+| OSS | 保存照片、海报、视频、音频和升级包等文件 |
+| DNP 打印机 | 实际输出照片，当前主要适配 RX1 和 QW410 |
+| 运维人员 | 配置设备密钥、局域网模式、纸张数、素材、打印机和应用版本 |
+
+整体关系如下：
+
+```mermaid
+flowchart LR
+    Visitor["游客"] --> Kiosk["Android KIOSK"]
+    Phone["手机端 / 微信"] <-->|"上传、支付、取片"| Backend["Oscar 业务后端"]
+    Kiosk <-->|"HTTPS API"| Backend
+    Kiosk <-->|"WebSocket 消息与心跳"| Backend
+    Kiosk <-->|"人脸检索、照片读取"| FaceBox["照片盒子 / 人脸服务"]
+    Backend <--> OSS["阿里云 OSS"]
+    Kiosk -->|"下载或上传素材"| OSS
+    Kiosk -->|"DNP SDK 打印任务"| Printer["RX1 / QW410 打印机"]
+    Operator["运维人员"] --> Kiosk
+```
+
+## 3. 用户能看到的主要业务
+
+### 3.1 首页
+
+首页是所有业务的入口，主要展示：
+
+- 人脸识别照片/打卡点照片打印入口
+- 上传手机照片打印入口
+- 微信扫码隐私取片二维码
+- 首页宣传视频
+- 当前打印任务状态
+- 剩余打印纸张数和客服电话
+
+首页双击特定区域会弹出管理密码，校验后进入设置页。首页 60 秒无操作，且当前没有打印任务时，会进入待机海报或直播层；用户触摸后返回首页。
+
+主要代码：
+
+- [`HomeScreen.kt`](../app/src/main/java/com/yzx/kiosk/ui/home/view/HomeScreen.kt)
+- [`HomeViewModel.kt`](../app/src/main/java/com/yzx/kiosk/ui/home/viewmodel/HomeViewModel.kt)
+- [`InactivityManager.kt`](../app/src/main/java/com/yzx/kiosk/utils/InactivityManager.kt)
+
+### 3.2 手机照片上传打印
+
+这是 `capture type = 1` 的业务。
+
+```mermaid
+sequenceDiagram
+    actor User as 游客
+    participant K as KIOSK
+    participant API as 业务后端
+    participant WS as WebSocket
+    participant P as DNP 打印机
+
+    User->>K: 进入“上传手机照片打印”
+    K->>API: 获取上传二维码和打印服务信息
+    K-->>User: 展示二维码、价格和规格
+    User->>API: 手机扫码并上传照片
+    WS-->>K: code=1 扫码成功
+    WS-->>K: code=2 下发 file_map 照片列表
+    K-->>User: 展示照片并选择
+    K->>API: verify-result 计算单价和总价
+    K->>API: get-pay-url 获取支付二维码
+    User->>API: 手机支付
+    WS-->>K: code=5 支付成功及订单信息
+    K-->>User: 支付成功，直接进入打印页
+    K->>P: 逐张下载、处理并打印
+    K->>API: print-notify 上报每张结果
+    K->>API: print-complete 上报订单完成
+```
+
+对应页面链路：
+
+```text
+首页
+  -> 上传照片二维码页 UploadPhotoScreen
+  -> 照片选择页 PhotoSelectScreen
+  -> 打印页 PrintingScreen
+  -> 自动返回首页
+```
+
+核心类：
+
+- [`UploadPhotoViewModel.kt`](../app/src/main/java/com/yzx/kiosk/ui/upload/viewmodel/UploadPhotoViewModel.kt)：加载上传二维码，监听扫码和文件列表事件
+- [`PhotoSelectViewModel.kt`](../app/src/main/java/com/yzx/kiosk/ui/upload/viewmodel/PhotoSelectViewModel.kt)：选片、计价、获取支付二维码，并在支付成功后直接进入打印页
+- [`PrintingViewModel.kt`](../app/src/main/java/com/yzx/kiosk/ui/upload/viewmodel/PrintingViewModel.kt)：逐张下载、打印、记录并上报结果
+
+服务端通过 `file_map` 同时下发 OSS 和局域网地址。客户端根据设置中的“使用 LAN”开关选择 `*_lan_url` 或 `*_oss_url`。
+
+### 3.3 人脸识别照片打印
+
+这是 `capture type = 2` 的业务，适用于景区相机、无人机或打卡点预先拍摄的照片。
+
+业务过程：
+
+1. 游客进入人脸识别页。
+2. CameraX 打开前置相机，支持 5 秒倒计时或手动拍照。
+3. 客户端把照片上传到照片盒子的 `/{sn}/api/search` 接口。
+4. 服务根据人脸相似度返回当天匹配的照片。
+5. 终端展示缩略图，游客选择照片。
+6. 客户端请求后端计算价格并生成支付二维码。
+7. WebSocket 或 HTTP 轮询确认支付成功后直接进入打印页。
+
+主要代码：
+
+- [`FaceRecognitionScreen.kt`](../app/src/main/java/com/yzx/kiosk/ui/face/view/FaceRecognitionScreen.kt)：相机页面
+- [`FaceRecognitionViewModel.kt`](../app/src/main/java/com/yzx/kiosk/ui/face/viewmodel/FaceRecognitionViewModel.kt)：拍照、方向修正和人脸检索
+- [`FaceRecognitionResultViewModel.kt`](../app/src/main/java/com/yzx/kiosk/ui/face/viewmodel/FaceRecognitionResultViewModel.kt)：结果展示、选片、计价和支付
+- [`FaceSearchService.kt`](../app/src/main/java/com/yzx/kiosk/network/service/FaceSearchService.kt)：人脸搜索 Retrofit 接口
+
+人脸服务地址、盒子 SN 和 Token 来自设备配置。设置为 LAN 模式时走局域网地址，否则走公网地址。
+
+### 3.4 微信扫码隐私取片
+
+隐私取片不是通过当前页面一步步操作，而是后台 WebSocket 直接下发的打印任务。
+
+处理过程：
+
+1. 首页显示服务端配置的微信隐私取片二维码。
+2. 用户在微信侧完成选片或确认。
+3. WebSocket 收到 `code = 4` 消息。
+4. `PrintQueueManager` 按订单去重并排队。
+5. `PrivacyPrintService` 依次下载照片并调用打印机。
+6. 首页顶部显示“手机尾号 xxxx 用户正在打印/打印完成”。
+7. 客户端上报单张结果和订单完成状态，并更新纸张余量。
+
+主要代码：
+
+- [`WebSocketService.kt`](../app/src/main/java/com/yzx/kiosk/websocket/WebSocketService.kt)
+- [`PrintQueueManager.kt`](../app/src/main/java/com/yzx/kiosk/websocket/PrintQueueManager.kt)
+- [`PrivacyPrintService.kt`](../app/src/main/java/com/yzx/kiosk/websocket/PrivacyPrintService.kt)
+- [`PrivacyPrintMessage.kt`](../app/src/main/java/com/yzx/kiosk/websocket/model/PrivacyPrintMessage.kt)
+
+这条链路允许游客在手机端操作打印时，终端屏幕继续服务其他用户，因此打印状态通过全局状态栏展示，而不是强制占用前台页面。
+
+### 3.5 打印机处理
+
+打印能力封装在 [`PrinterService.kt`](../app/src/main/java/com/yzx/kiosk/priter/PrinterService.kt) 中，底层使用 DNP 本地 AAR/JNI SDK。
+
+当前处理步骤：
+
+1. 枚举打印机端口并保存打印机 ID。
+2. 根据 ID 区分 RX1 和 QW410。
+3. 按打印机方向旋转原图。
+4. 保持原比例缩放，居中绘制到白色背景画布。
+5. 保存为 300 DPI BMP 文件。
+6. 创建 `PrintJob` 并加入 DNP `PrintQueue`。
+7. 更新打印状态、打印记录和纸张余量。
+
+尺寸配置位于 [`PRINTSIZE.kt`](../app/src/main/java/com/yzx/kiosk/priter/PRINTSIZE.kt)：
+
+| 打印机 | 画布尺寸 | 方向 |
+| --- | --- | --- |
+| DNP RX1 | 1840 × 1240 | 横向 |
+| DNP QW410 | 1266 × 1836 | 纵向 |
+
+工程里的打印包目录名是历史拼写 `priter`，并不是文档笔误。
+
+### 3.6 待机广告、直播和语音
+
+设备配置接口会下发海报、背景音乐、首页视频及直播信息。
+
+- 图片/视频海报使用 Compose + Media3 展示
+- 首页底部视频通过 ExoPlayer 循环播放
+- 景区直播通过 RTMP 地址播放
+- WebSocket 绑定成功后发送 `type = 304` 订阅直播变化
+- 本地页面引导语音由 `LocalAudioPlayService` 管理
+- 网络 BGM 和其他音频由 `AudioPlayService` 管理
+- 打印通知还可通过阿里云语音合成播报
+
+主要代码：
+
+- [`PosterScreenWithLiveOrSlideshow.kt`](../app/src/main/java/com/yzx/kiosk/ui/poster/view/PosterScreenWithLiveOrSlideshow.kt)
+- [`ScenicLivePosterController.kt`](../app/src/main/java/com/yzx/kiosk/ui/poster/ScenicLivePosterController.kt)
+- [`AudioPlayService.kt`](../app/src/main/java/com/yzx/kiosk/audio/AudioPlayService.kt)
+- [`LocalAudioPlayService.kt`](../app/src/main/java/com/yzx/kiosk/audio/LocalAudioPlayService.kt)
+
+### 3.7 设备管理和运营配置
+
+设置页用于现场运维，主要包括：
+
+- 切换公网/局域网照片地址
+- 设置剩余打印纸张数
+- 打开设备配置页和打印机管理页
+- 查看帮助中心、关于我们和协议页面
+- 手动检查应用更新
+
+设备配置页还可以维护：
+
+- 设备密钥
+- 景区和客服电话
+- 隐私取片二维码开关
+- 首页直播和新版首页开关
+- 最多 5 个已选海报
+- 背景音乐
+- 上传自定义图片、视频和音频素材
+
+运营配置既会调用 `/api/oscar/config/set` 保存到后端，也会同步一部分到本地 MMKV，供首页立即读取。
+
+主要代码：
+
+- [`SettingViewModel.kt`](../app/src/main/java/com/yzx/kiosk/ui/setting/viewmodel/SettingViewModel.kt)
+- [`DeviceConfigViewModel.kt`](../app/src/main/java/com/yzx/kiosk/ui/device/viewmodel/DeviceConfigViewModel.kt)
+- [`PrinterManageViewModel.kt`](../app/src/main/java/com/yzx/kiosk/ui/printer/viewmodel/PrinterManageViewModel.kt)
+
+### 3.8 在线升级与设备自启动
+
+`VersionUpdateManager` 请求 `type = 8` 的最新 Android 终端版本，下载 APK 后通过 `FileProvider` 拉起系统安装界面。Manifest 同时注册了开机和包更新广播，目标是让自助终端重启或升级后恢复运行。
+
+主要代码：
+
+- [`VersionUpdateManager.kt`](../app/src/main/java/com/yzx/kiosk/utils/VersionUpdateManager.kt)
+- [`BootReceiver.kt`](../app/src/main/java/com/yzx/kiosk/receiver/BootReceiver.kt)
+- [`AndroidManifest.xml`](../app/src/main/AndroidManifest.xml)
+
+## 4. 应用启动时发生什么
+
+```text
+应用进程启动，App.onCreate 完成全局初始化
+  -> 系统或桌面启动 SplashActivity
+  -> 等待约 1.5 秒
+  -> 进入 MainActivity
+  -> 初始化无操作检测并注册 WebSocket 监听器
+  -> MainActivity 获取 Socket Token
+  -> WebSocket 连接并发送 type=1000 绑定设备
+  -> Compose 创建 AppNavHost 并进入首页
+  -> HomeViewModel 拉取设备配置
+  -> 每 5 秒发送 type=1001 心跳
+  -> 首页开始展示入口、二维码、视频和纸张信息
+  -> 无操作 60 秒后展示待机海报或直播
+```
+
+Application 级初始化在 [`App.kt`](../app/src/main/java/com/yzx/kiosk/App.kt) 中完成，包括 Hilt、MMKV、日志、Toast、Coil 缓存和全局状态初始化。DNP SDK 延迟到第一次使用打印机时初始化。
+
+## 5. WebSocket 协议在客户端中的作用
+
+WebSocket 是业务闭环的关键，不只是普通通知。当前客户端使用的主要消息如下：
+
+| 方向 | 类型或 code | 含义 |
+| --- | --- | --- |
+| 客户端 -> 服务端 | `type = 1000` | 使用 Socket Token 绑定设备 |
+| 客户端 -> 服务端 | `type = 1001` | 心跳，上报设备、打印机状态和剩余纸张 |
+| 客户端 -> 服务端 | `type = 304` | 订阅景区直播状态 |
+| 服务端 -> 客户端 | `code = 1` | 手机扫码成功 |
+| 服务端 -> 客户端 | `code = 2` | 上传照片列表到达 |
+| 服务端 -> 客户端 | `code = 4` | 隐私取片打印任务 |
+| 服务端 -> 客户端 | `code = 5` | 支付成功，包含订单和照片信息 |
+| 服务端 -> 客户端 | `code = 100000` | 绑定、心跳或直播动作成功 |
+| 服务端 -> 客户端 | `code = 100099` | Token 失效，需要刷新并重新绑定 |
+
+`WebSocketService` 把上传/支付类消息转换为 `SharedFlow<UploadPhotoEvent>`，页面 ViewModel 各自订阅；隐私打印则直接进入后台打印队列。
+
+## 6. 网络认证和环境
+
+普通 HTTP 请求由 [`RequestInterceptor.kt`](../app/src/main/java/com/yzx/kiosk/network/interceptor/RequestInterceptor.kt) 添加：
+
+```text
+sn        = 设备 SN
+timestamp = 当前秒级时间戳
+token     = MD5(sn + deviceSecret + timestamp)
+```
+
+设备密钥需要先在设备配置页录入。没有密钥时客户端不会生成 `token` 请求头，首页会提示先配置设备密钥。
+
+构建环境由 `BuildConfig` 区分：
+
+| 构建类型 | HTTP API | WebSocket |
+| --- | --- | --- |
+| Debug | `api-test.zhifly.cn` | 测试 WSS |
+| Release | `api.zhifly.cn` | 正式 WSS |
+
+配置位置为 [`app/build.gradle.kts`](../app/build.gradle.kts)，网络组件装配位于 [`NetworkModule.kt`](../app/src/main/java/com/yzx/kiosk/network/di/NetworkModule.kt)。
+
+## 7. 工程采用的技术
+
+### 7.1 语言、构建和 UI
+
+| 技术 | 用途 |
+| --- | --- |
+| Kotlin 2.1.10 | 主要开发语言，JVM Target 11 |
+| Gradle 8.11.1 + AGP 8.10.0 | Android 构建系统 |
+| Jetpack Compose + Material 3 | 主要页面 UI |
+| ViewBinding + XML | Splash 等少量传统页面 |
+| Navigation Compose | 页面路由和回退栈 |
+| StateFlow / SharedFlow | 页面状态、全局状态和实时事件 |
+| Coroutines | 网络、打印、上传下载和倒计时等异步任务 |
+
+整体采用接近单 Activity + MVVM 的结构：
+
+```mermaid
+flowchart TD
+    UI["Compose Screen"] --> VM["Hilt ViewModel"]
+    VM --> Repo["Repository / Manager"]
+    Repo --> Api["Retrofit Service"]
+    Repo --> Local["Room / MMKV"]
+    VM --> Device["打印机、相机、播放器"]
+    WS["WebSocketService"] --> Flow["SharedFlow / StateFlow"]
+    Flow --> VM
+    VM --> Nav["AppNavigator"]
+    Nav --> UI
+```
+
+### 7.2 依赖注入和架构组件
+
+- Hilt：Application、Activity、ViewModel、Repository 和 Service 的依赖注入
+- KSP：Hilt、Room 和 Glide 等代码生成
+- Lifecycle ViewModel：页面状态和协程生命周期
+- 自定义 `AppNavigator`：通过 SharedFlow 解耦 ViewModel 与 NavController
+- `BaseViewModel`：统一导航、Loading、网络结果和登录失效处理
+
+### 7.3 网络与实时通信
+
+- Retrofit + Gson：业务 REST API
+- OkHttp：HTTP、APK 下载和 WebSocket
+- 自定义请求拦截器：设备 SN、时间戳和签名 Token
+- 自定义响应拦截器与结果层：统一解析业务 code
+- WebSocket：扫码、照片列表、支付成功、隐私打印、直播和设备心跳
+
+### 7.4 数据存储
+
+| 存储 | 保存内容 |
+| --- | --- |
+| MMKV | 设备密钥、设备配置、Socket Token、盒子地址、纸张数、打印记录和开关状态 |
+| Room `AppDatabase` | 运营素材上传任务及进度 |
+| Room `CloudDatabase` | OSS 上传、下载任务 |
+| 应用私有文件目录 | 处理后的打印 BMP、缓存和下载文件 |
+| Coil 磁盘缓存 | 网络图片缓存，当前限制约 50 MB |
+
+MMKV 的统一访问入口是 [`AppStoreDataSource.kt`](../app/src/main/java/com/yzx/kiosk/datastore/AppStoreDataSource.kt)，全局响应式状态集中在 [`AppState.kt`](../app/src/main/java/com/yzx/kiosk/datastore/AppState.kt)。
+
+### 7.5 图片、相机和扫码
+
+- CameraX：人脸识别页拍照
+- Coil / Glide：网络图片加载
+- uCrop：照片裁剪
+- PictureSelector：本地运营素材选择
+- ML Kit Barcode Scanning + ZXing：扫码识别和二维码生成
+- Android Bitmap/Canvas：打印前旋转、缩放和白底合成
+
+### 7.6 音视频与云能力
+
+- AndroidX Media3 / ExoPlayer：视频、音频和 RTMP 直播
+- 阿里云 OSS SDK：素材上传下载
+- 阿里云语音 SDK：状态语音合成
+- 高德地图 SDK：定位相关能力
+- DNP PhotoPrint SDK：照片打印机控制
+
+本地闭源 SDK 位于 `app/libs/`，这是工程能否完整构建和连接硬件的重要前提。

+
+## 9. 建议的代码阅读顺序
+
+第一次接手时，不建议从工具类或所有依赖开始看。按下面顺序更容易建立上下文：
+
+1. [`README.md`](../README.md)：先把工程跑起来，理解环境和硬件要求。
+2. [`AppRoutes.kt`](../app/src/main/java/com/yzx/kiosk/navigation/routes/AppRoutes.kt) 和 [`AppNavHost.kt`](../app/src/main/java/com/yzx/kiosk/navigation/AppNavHost.kt)：知道有哪些页面和用户动线。
+3. [`HomeScreen.kt`](../app/src/main/java/com/yzx/kiosk/ui/home/view/HomeScreen.kt) 和 [`HomeViewModel.kt`](../app/src/main/java/com/yzx/kiosk/ui/home/viewmodel/HomeViewModel.kt)：理解首页配置如何驱动业务入口。
+4. `ui/upload/viewmodel/`：完整看一遍上传、选片、支付、打印主链路。
+5. `ui/face/viewmodel/`：理解第二条照片来源链路。
+6. [`WebSocketService.kt`](../app/src/main/java/com/yzx/kiosk/websocket/WebSocketService.kt)：理解页面为什么会因服务端消息自动跳转。
+7. [`PrinterService.kt`](../app/src/main/java/com/yzx/kiosk/priter/PrinterService.kt) 和 [`PrivacyPrintService.kt`](../app/src/main/java/com/yzx/kiosk/websocket/PrivacyPrintService.kt)：理解硬件和后台任务。
+8. [`NetworkService.kt`](../app/src/main/java/com/yzx/kiosk/network/service/NetworkService.kt) 与 [`AppStoreDataSource.kt`](../app/src/main/java/com/yzx/kiosk/datastore/AppStoreDataSource.kt)：梳理接口和持久化字段。
+9. `ui/device/`、`utils/cloud/` 和 `VersionUpdateManager`：最后看运营配置、素材和升级能力。
+10. [`工程代码审查报告.md`](工程代码审查报告.md)：了解当前缺陷和发布风险。
+
+## 10. 接手时最容易混淆的几个概念
+
+### capture type
+
+- `1`：用户从手机上传的照片
+- `2`：通过人脸搜索得到的景区照片
+
+它会贯穿计价、支付、打印通知和订单完成接口。
+
+### file_map
+
+一张照片不只有一个 URL，而是同时包含图片 ID、OSS 原图/缩略图地址和 LAN 原图/缩略图地址。打印必须保留图片 ID，服务端才能正确记录每张照片的状态。
+
+### 设备 SN、设备密钥和 Socket Token
+
+- 设备 SN：当前主要取 Android ID，标识终端
+- 设备密钥：运维录入，用于普通 HTTP 请求签名
+- Socket Token：后端接口动态获取，用于 WebSocket 绑定
+
+这三个值用途不同，排查鉴权问题时不要混在一起。
+
+### 公网模式和 LAN 模式
+
+切换的是照片盒子服务和照片 URL 的访问方式，不是 Debug/Release 环境切换。Debug/Release 由构建类型决定，LAN/公网由设备设置决定。
+
+### 两类打印
+
+- 前台打印：游客在终端完成上传/人脸业务后进入 `PrintingScreen`
+- 后台隐私打印：WebSocket `code = 4` 直接进入 `PrivacyPrintService`
+
+两条链路最终都调用 `PrinterService`，但任务队列、UI 展示和状态上报入口不同。
+
+## 11. 接手后的优先验证清单
+
+在开始改业务前，建议用测试环境完成以下闭环：
+
+1. 配置设备密钥，确认设备配置接口成功。
+2. 确认 WebSocket 绑定成功且心跳包含正确纸张和打印机状态。
+3. 手机扫码上传一张照片，走完选片、计价和支付事件。
+4. 使用相机完成一次人脸搜索，分别测试公网和 LAN 地址。
+5. 连接 RX1 或 QW410，各打印一张横图和竖图。
+6. 验证单张 `print-notify` 和最终 `print-complete` 到达服务端。
+7. 发送一条隐私打印任务，确认不会阻断前台用户操作。
+8. 验证海报、视频、直播、BGM 和无操作返回逻辑。
+9. 验证重启后开机自启动、配置恢复和 Socket 重连。
+10. 在准备发布前阅读代码审查报告并处理签名、隐私、打印结果和并发问题。
+
+## 12. 当前需要特别注意的技术债
+
+本文重点是业务和技术导读，不展开缺陷细节；但以下问题会直接影响你对现有实现的判断：
+
+- Release 当前实际使用 Debug 签名，且签名信息直接写在 Gradle 配置中。
+- 打印任务加入 SDK 队列后不等于物理打印成功，当前成功判定不够可靠。
+- 部分 Token、设备密钥和业务配置保存在未加密 MMKV 中。
+- WebSocket、打印通知及上传下载存在并发和恢复方面的风险。
+- APK 更新缺少足够的完整性与签名校验。
+- 自动化测试覆盖少，Lint 当前仍有待处理项。
+
+具体证据、文件位置和修复建议见 [`工程代码审查报告.md`](工程代码审查报告.md)。
+
+---
+
+如果要修改某个业务，优先从对应页面的 ViewModel 顺着 Repository、WebSocket 或 PrinterService 向下追踪；如果问题表现为“页面没有自动跳转”，通常还要同时检查 WebSocket 消息是否到达以及 `SharedFlow` 订阅是否仍处于活跃生命周期。
