-bash ./scripts/package-sdk.sh --source-dir ./out/linux/bin --output-dir ./dist/UpdateClientSDK-linux --archive ./dist/UpdateClientSDK-linux.tar.gz --sdk-version 0.1.0
-```
-
-客户端配置速记
-==============
-
-config/app_config.json 是部署配置源文件。Launcher / Updater / MainApp 启动时会把它同步到当前用户的 QSettings 配置区；Windows 下对应注册表，Linux 下对应用户配置文件。后续运行配置优先从 QSettings 读取。
-config/server_config.json 是编译期服务端地址配置源文件。它通过 config/server_config.qrc 编进 Launcher / Updater / MainApp，不写入 app_config.json，也不写入注册表。修改 api_base_url 后必须重新编译客户端程序才会生效。
-如果 config/app_config.json 内容被修改，下一次启动时会按解析后的 JSON 内容 SHA256 判断变化并重新导入注册表。
-非空 app_config.json 成功导入注册表后会自动清空为 {}，文件保留不删除，方便下次直接粘贴管理后台生成的新配置。
-Windows 注册表位置：HKEY_CURRENT_USER\Software\Marsco\UpdateClientSDK\installations\<安装目录SHA256>\config。
-Linux 配置位置由 Qt QSettings 决定，通常在当前用户 home 目录的 .config/Marsco/UpdateClientSDK.conf 一类路径下。
-Windows 运行态数据目录类似：%LOCALAPPDATA%\Marsco\UpdateClientSDK\installations\<安装目录SHA256>\。
-如果检测到 app_config.json 发生变化，SDK 会删除当前用户数据目录里的 client_identity.dat、version_policy.dat 和 local_state.json，避免继续使用旧授权身份、旧策略或旧防回滚状态；这些运行态文件不再默认写入安装目录。
-正常启动成功后不要删除这些状态文件，它们用于本地身份、离线策略和安全状态。
-首次运行时如果该文件不存在且发现旧 client.ini，会自动迁移。
-
-接入新软件时通常需要修改：
-
-1. app_id、app_name、channel、current_version。
-2. client_token、license_key、launch_token。
-3. config/server_config.json 里的 api_base_url。
-4. main_executable：团队业务主程序文件名。
-5. launcher_executable、updater_executable、bootstrap_executable。
-6. health_check_timeout_ms：升级后等待业务程序健康确认的毫秒数，最小 1000。
-
-Windows 完整格式参考 update-client/config/app_config.example.json；Linux 完整格式参考 update-client/config/app_config.linux.example.json。
-运行时生成的 client_identity.dat、local_state.json 等文件不得打入通用 SDK 模板。app_config.json 可以作为部署模板，但不要把某台机器运行后产生的临时状态混进去。
-
-Windows 发布打包：
-
-1. 使用 Release 配置编译全部客户端程序。
-2. 先完成当前版本在线校验。签名 Manifest 缓存现在默认保存在当前用户数据目录：
-   Windows：%LOCALAPPDATA%\Marsco\UpdateClientSDK\installations\<安装目录SHA256>\update\manifest_cache
-   Linux：$XDG_DATA_HOME/Marsco/UpdateClientSDK/installations/<安装目录SHA256>/update/manifest_cache，未设置 XDG_DATA_HOME 时通常是 ~/.local/share。
-   打包脚本会优先从用户数据目录读取，也兼容旧版 Release 目录里的 update/manifest_cache。
-3. 准备一份实际 app_config.json，确认其中包含正确的 License Key、当前版本和业务程序名；确认客户端程序已用正确的 config/server_config.json 编译。
-4. 在 PowerShell 执行：
-   powershell -ExecutionPolicy Bypass -File .\scripts\package-client.ps1 -ConfigFile .\config\app_config.json
-5. 输出位于 dist/UpdateClient 和 dist/UpdateClient.zip。
-
-脚本会拒绝 Debug DLL、PDB、嵌套重复主程序和缺少签名 Manifest 的发布源目录。

-# UpdateClientSDK 客户端接入、打包和部署指南
-
-本文按“维护者打包 SDK -> 你接入业务软件 -> 联调测试 -> 生成最终客户端包”的顺序说明。你拿到这份文档后，按章节一步一步做即可。
-
-## 先看这里：你要做哪件事
-
-| 你的目标 | 直接看哪一节 |
-| --- | --- |
-| 重新生成给别人用的 SDK 包 | 二、维护者：生成 SDK 包 |
-| 把 SDK 放到 SimCAE 或其他业务软件目录 | 三、你：把 SDK 放进业务软件目录 |
-| 从后台生成 `app_config.json` 和 qrc 服务端配置 | 四、你：生成并填写客户端配置 |
-| 给业务主程序接入启动保护代码 | 五、你：业务主程序接入要求 |
-| 验证升级、回滚、健康检查 | 六、你：联调测试 |
-| 生成最终交付给用户的客户端包 | 七、维护者：生成最终客户端包 |
-
-## 一、这个 SDK 是什么
-
-UpdateClientSDK 是“独立更新器 SDK / 升级运行时 SDK”。它不是传统的 `include + lib` 形态，而是把自动升级能力做成一组独立程序，让业务软件通过这些程序完成检查更新、下载、安装、回滚和启动保护。
-
-SDK 核心程序：
-
-- `Launcher.exe` / `Launcher`：用户入口。检查版本、验证授权和策略，决定直接启动业务主程序或进入升级流程。
-- `Updater.exe` / `Updater`：下载、校验、备份、安装、健康确认、提交或回滚。
-- `Bootstrap.exe` / `Bootstrap`：处理运行中可能被占用的 EXE/DLL 或 Linux 可执行文件替换。
-- `config/app_config.json`：部署配置源文件。启动时会同步到当前用户的 QSettings 配置区；Windows 下对应注册表，Linux 下对应用户配置文件。
-- `config/server_config.json`：编译期服务端地址配置源文件，通过 `config/server_config.qrc` 编进 Launcher / Updater / MainApp，不写入 `app_config.json` 或注册表。
-- `config/manifest_public_key.pem`：Manifest 签名公钥，用来验证服务端发布包没有被篡改。
-
-## 二、维护者：生成 SDK 包
-
-这一节是 SDK 维护者操作。接入方通常只需要拿到 `UpdateClientSDK.zip`。
-
-打包前确认：
-
-1. 已在 Windows 上用 Release 配置编译完成，输出目录里有 `Launcher.exe`、`Updater.exe`、`Bootstrap.exe`。
-2. `config/manifest_public_key.pem` 和服务端使用的私钥是一对。
-3. `update-client/Docs` 里的 Markdown 文档会随 SDK 一起打包，是默认接入说明来源。
-4. Word 接入说明是可选增强。如果本地有文件名包含 `SDK` 的 `.docx`，打包脚本会额外复制到 SDK 根目录；如果没有，也不会影响 SDK 打包。
-5. 如果业务软件本身已经带 Qt DLL，通常不要把 SDK 的 Qt 运行库打进去，避免 Qt 版本混用。
-
-在 Windows PowerShell 中执行：
-
-```powershell
-cd C:\Users\admin\Desktop\update-client
-
-.\scripts\package-sdk.ps1 `
-  -SourceDir .\out\bin\Release `
-  -OutputDir .\dist\UpdateClientSDK `
-  -ZipFile .\dist\UpdateClientSDK.zip `
-  -SdkVersion 0.1.0
-```
-
-生成结果：

-  UpdateClientSDK.zip
-```
-
-把 `dist/UpdateClientSDK.zip` 发给接入方即可。
-
-可选参数：
-
-- `-IncludeDemoMainApp`：把仓库里的 Demo 主程序 `MainApp.exe` 也打进 SDK，方便演示。
-- `-IncludeQtRuntime`：把 Qt 运行库也打进 SDK。只有业务软件本身不带 Qt 时才建议使用。
-
-Linux SDK 打包方式：
-
-```bash
-cd /home/laluo/project/update-client
-
-cmake --preset linux-x64-release
-cmake --build --preset linux-x64-release
-
-bash ./scripts/package-sdk.sh \
-  --source-dir ./out/linux/bin \
-  --output-dir ./dist/UpdateClientSDK-linux \
-  --archive ./dist/UpdateClientSDK-linux.tar.gz \
-  --sdk-version 0.1.0
-```
-
-Linux SDK 包里核心程序名不带 `.exe`：

-  UpdateClientSDK-linux.tar.gz
-```
-
-## 三、你：把 SDK 放进业务软件目录
-
-假设业务软件目录是：
-
-```text
-D:\SimCAE\
-  bin\
-    SimCAE.exe
-    Qt5Core.dll
-    ...
-  Licenses\
-  installerResources\
-```
-
-推荐把 SDK 放到 `bin` 目录，和 `SimCAE.exe` 同级；后台发布新版本时仍选择整个 `D:\SimCAE\` 作为发布根目录。
-
-先解压 SDK：
-
-```powershell
-Expand-Archive D:\交付\UpdateClientSDK.zip -DestinationPath D:\SimCAE_SDK -Force
-```
-
-再安装到业务软件的 `bin` 目录：
-
-```powershell
-cd D:\SimCAE\bin
-
-D:\SimCAE_SDK\scripts\install-sdk.ps1 `
-  -SdkRoot D:\SimCAE_SDK `
-  -ReleaseDir .
-```
-
-安装后目录应类似：
-
-```text
-D:\SimCAE\
-  bin\
-    Launcher.exe
-    Updater.exe
-    Bootstrap.exe
-    SimCAE.exe
-    config\
-      app_config.json
-      manifest_public_key.pem
-    Qt5Core.dll
-    ...
-  Licenses\
-  installerResources\
-```
-
-如果你需要重新覆盖 `config/app_config.json`，执行安装脚本时加 `-OverwriteConfig`：
-
-```powershell
-D:\SimCAE_SDK\scripts\install-sdk.ps1 `
-  -SdkRoot D:\SimCAE_SDK `
-  -ReleaseDir D:\SimCAE\bin `
-  -OverwriteConfig
-```
-
-注意：SimCAE 自己已经带有 Qt 运行库。SDK 的 Launcher/Updater 应复用 SimCAE 的 `Qt5*.dll`、`platforms/`、`imageformats/` 等目录。不要把另一套 Qt DLL 覆盖到 `SimCAE\bin`，否则可能出现“无法定位程序输入点”一类错误。
-
-## 四、你：生成并填写客户端配置
-
-最推荐的方式是在服务端管理后台生成客户端配置：
-
-1. 浏览器打开服务端管理后台，例如 `http://服务器IP:8000/`。
-2. 登录后台。
-3. 创建或选择应用，例如 `app_id=simcae`。
-4. 创建 License。
-5. 在“客户端配置生成”区域选择应用、渠道、License 和主程序名。
-6. 点击生成配置。
-7. 复制“客户端 app_config.json”，覆盖 `D:\SimCAE\bin\config\app_config.json`。
-8. 复制“qrc 服务端配置 server_config.json”，覆盖 `update-client\config\server_config.json`，然后重新编译 Launcher / Updater / Bootstrap。这个文件会被 `config/server_config.qrc` 编进程序，不会放进用户机器的 `app_config.json` 或注册表。
-
-配置同步规则：
-
-- `app_config.json` 是部署配置源文件，适合交付、复制、人工修改。
-- `api_base_url` 不再属于 `app_config.json` 字段。它只存在于 `config/server_config.json`，并通过 qrc 编进程序。
-- 交付给你的 SDK 运行包不会包含 `server_config.json` 和 `server_config.qrc`。它们是编译材料，不是运行配置；修改 SDK 包里的文件不会改变已经编译好的 `Launcher.exe`。
-- Launcher / Updater / MainApp 启动时会计算 `app_config.json` 解析后的 JSON 内容 SHA256；如果 JSON 内容和上次导入时不同，就把文件里的配置重新写入当前 Windows 用户的注册表。
-- 后续运行时优先从注册表读取配置，不再每次直接读 JSON。
-- 运行过程中产生的动态值，例如首次输入的 `license_key`、服务端返回的 `device_id`、升级后的 `current_version`，会写入注册表。
-- 为减少明文暴露，SDK 成功把非空 `app_config.json` 导入注册表后，会把 `app_config.json` 内容自动清空为 `{}`，但不会删除这个文件。以后你从管理后台复制新的客户端配置时，直接覆盖这个文件即可。
-- SDK 会同步更新注册表里的 `source_sha256`，所以 `{}` 不会在下一次启动时反向覆盖注册表配置。
-- 如果你手动修改了 `app_config.json`，下一次启动会重新导入并覆盖注册表里的同名字段。
-- 如果检测到 `app_config.json` 确实发生变化，SDK 会同时删除当前用户数据目录里的 `client_identity.dat`、`version_policy.dat` 和 `local_state.json`，避免继续使用旧 License、旧设备身份、旧版本策略或旧防回滚状态；这些运行态文件不再默认写入安装目录。
-- 正常启动成功后，不要删除 `client_identity.dat`、`version_policy.dat`、`local_state.json`。它们分别用于本地设备身份、离线策略和防回滚/防时间倒退，删除后会影响离线启动或导致重新授权。
-- 注册表按安装目录隔离；同一台电脑上多个安装目录不会互相覆盖配置。
-- 注册表位置为 `HKEY_CURRENT_USER\Software\Marsco\UpdateClientSDK\installations\<安装目录SHA256>\config`。
-
-关键字段说明：
-
-- `app_id`：服务端应用 ID，要和管理后台里的应用一致。
-- `app_name`：应用显示名称。
-- `channel`：发布渠道，例如 `stable`、`beta`、`dev`。
-- `current_version`：客户端当前初始版本，必须和后台已发布的版本一致。
-- `client_protocol`：客户端协议号，当前建议为 `3`。
-- `launch_token`：本机启动票据 HMAC 密钥。服务端生成配置时会填默认值；正式部署建议按项目统一修改。
-- `license_key`：管理后台创建 License 后生成的授权码。为空时首次启动 `Launcher.exe` 会弹窗让用户输入并保存到注册表；如果授权错误或过期，也会提示重新输入。
-- `client_token`：服务端 `.env` 中的 `CLIENT_API_TOKEN`，必须和服务端一致。
-- `device_id`：设备 ID。一般可以留空，首次启动时 SDK 会向服务端登记并写入注册表。
-- `install_root`：被更新的安装根目录相对 `Launcher.exe` 所在目录的位置。SDK 放在 `bin` 时填 `..`。
-- `main_executable`：业务主程序相对 `Launcher.exe` 所在目录的路径。SDK 放在 `bin` 且主程序也在 `bin` 时填 `SimCAE.exe`。
-- `launcher_executable`、`updater_executable`、`bootstrap_executable`：通常不用改。
-- `platform`、`arch`：当前为 `windows`、`x64`。
-
-典型配置：
-
-```json
-{
-  "app_id": "simcae",
-  "app_name": "SimCAE",
-  "channel": "stable",
-  "current_version": "1.0.0",
-  "client_protocol": "3",
-  "launch_token": "SimCAE_Launch_Token_2026_ChangeMe_32Bytes",
-  "license_key": "MARSCO-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
-  "client_token": "SimCAEClientToken2026",
-  "request_timeout_ms": "5000",
-  "temp_folder": "update_temp",
-  "device_id": "",
-  "install_root": "..",
-  "main_executable": "SimCAE.exe",
-  "launcher_executable": "Launcher.exe",
-  "updater_executable": "Updater.exe",
-  "bootstrap_executable": "Bootstrap.exe",
-  "health_check_timeout_ms": "15000",
-  "platform": "windows",
-  "arch": "x64"
-}
-```
-
-对应的 `config/server_config.json` 示例：
-
-```json
-{
-  "api_base_url": "http://192.168.229.128:8000"
-}
-```
-
-## 五、你：业务主程序需要配合什么
-
-当前安全模式下，业务主程序需要配合两件事：
-
-1. 接收 `--ticket-file=<path>` 参数，验证并消费一次性启动票据。
-2. 如果收到 `--health-file=<path>` 参数，启动成功后向该路径写入 `ok\n`，让 Updater 确认新版本可用。
-
-接入位置：
-
-```text
-main / WinMain 开头，创建主窗口之前
-```
-
-当前仓库里的 `update-client/MainApp/main.cpp` 是接入示例，已经实现：
-
-- 启动票据校验。
-- 本地 License/设备身份校验。
-- 本地策略校验。
-- Manifest 完整性校验。
-- 健康标记写入。
-
-真正接入业务软件时，把这些启动检查逻辑移植到业务主程序。用户入口应改成 `Launcher.exe`，不要让用户直接双击 `SimCAE.exe`。
-
-重要：业务主程序校验 ticket 时，必须使用 SDK 当前运行配置里的动态值，不要直接从 `app_config.json` 读取 `device_id`。
-
-原因是 `app_config.json` 是部署源文件，网页生成时 `device_id` 通常为空；真正的设备 ID 是 `Launcher.exe` 首次向服务端登记后写入当前用户注册表的。`Launcher.exe` 生成 ticket 时使用的是注册表里的真实 `device_id`。如果业务主程序从 `app_config.json` 读取空的 `device_id` 来校验，就会出现：
-
-```text
-ticket signature, identity, time or nonce invalid
-```
-
-或者细化后的：
-
-```text
-ticket device_id mismatch
-```
-
-业务主程序应像 `MainApp/main.cpp` 示例一样使用：
-
-```cpp
-ConfigHelper& config = ConfigHelper::instance();
-TicketHelper::consumeAndVerify(
-    ticketFilePath,
-    config.getValue("App", "app_id"),
-    config.getValue("Update", "device_id"),
-    config.getValue("App", "current_version"),
-    config.getValue("App", "launch_token"),
-    &ticketError);
-```
-
-也就是说，接入业务主程序时不能只复制一小段 ticket 代码后自己解析 JSON；要么复用 SDK 的 `ConfigHelper` / `TicketHelper`，要么保证业务主程序读取到的 `app_id`、`device_id`、`current_version`、`launch_token` 和 `Launcher.exe` 完全来自同一套运行配置。
-
-## 六、你：准备服务端数据
-
-首次联调前，服务端至少要准备这些内容：
-
-1. 创建应用，例如 `simcae`。
-2. 创建渠道，例如 `stable`。
-3. 创建 License。
-4. 发布一个初始版本，例如 `1.0.0`。
-5. 生成客户端配置，并写入 `bin\config\app_config.json`。客户端下次启动时会自动同步到注册表。
-6. 生成 qrc 服务端配置，并写入源码目录 `config\server_config.json` 后重新编译 SDK 程序。
-
-为什么必须先发布初始版本：Launcher 启动业务主程序前会做 Manifest 完整性校验。这个 Manifest 是服务端发布版本时生成并签名的清单，用来证明当前本地文件属于一个可信版本。如果没有发布过 `current_version` 对应版本，客户端会提示签名 Manifest 缓存缺失。
-
-后台发布版本时，选择整个安装根目录，例如 `D:\SimCAE\`，不要只选择 `D:\SimCAE\bin`。这样服务端会把 `bin/SimCAE.exe`、`Licenses/`、`installerResources/` 等完整结构写进 Manifest。
-
-## 七、你：运行和联调
-
-基础联调步骤：
-
-1. 确认服务端正在运行。
-2. 确认 `bin\config\app_config.json` 中 `client_token`、`license_key`、`current_version` 正确，并确认 `Launcher.exe` 已用正确的 `config/server_config.json` 重新编译。
-3. 双击 `bin\Launcher.exe`。
-4. 首次启动时如果 `license_key` 为空，按弹窗输入后台创建的 License；SDK 会把它保存到注册表。
-5. 成功进入业务主程序后，回到后台查看设备、升级日志、下载日志。
-6. 在后台发布更高版本，例如从 `1.0.0` 发布到 `1.0.1`。
-7. 再次启动 `Launcher.exe`，验证升级、健康确认和回滚逻辑。
-
-联调目录建议：
-
-```text
-D:\SimCAE_Release\
-C:\Users\<你的用户名>\Desktop\SimCAE_Release\
-```
-
-如果安装在 `C:\Program Files\...`、`D:\...` 或其他普通用户不一定可写的目录，SDK 的普通配置值会写入当前用户注册表，不需要修改 `app_config.json`。`client_identity.dat`、`local_state.json`、`version_policy.dat`、更新缓存和 Manifest 缓存也会写入当前用户数据目录，不再默认写到安装目录。
-
-Windows 用户数据目录类似：`%LOCALAPPDATA%\Marsco\UpdateClientSDK\installations\<安装目录SHA256>\`。因此日常启动、首次授权、保存设备身份、保存策略、防回滚状态和下载缓存不应再触发管理员权限确认框。只有真正要替换安装目录里的 EXE/DLL 等程序文件时，才需要保证安装目录可写，或让安装器/Updater 具备相应权限。
-
-## 八、维护者：生成某个产品的最终客户端包
-
-SDK 是给接入方开发使用的。最终给用户安装或分发时，可以从已经联调过的 Release 目录生成最终客户端包。
-
-在 Windows PowerShell 中执行：
-
-```powershell
-cd C:\Users\admin\Desktop\update-client
-
-.\scripts\package-client.ps1 `
-  -SourceDir .\out\bin\Release `
-  -ConfigFile .\config\app_config.json `
-  -OutputDir .\dist\UpdateClient `
-  -ZipFile .\dist\UpdateClient.zip
-```
-
-`package-client.ps1` 会检查：
-
-- 配置文件必填字段是否完整。
-- 主程序、Launcher、Updater、Bootstrap 是否存在。
-- 是否混入 Debug DLL、PDB、ILK。

-Linux 打包脚本会检查：
-
-- `app_config.json` 必填字段是否完整。
-- 主程序、Launcher、Updater、Bootstrap 是否存在。
-- 是否混入 Debug 产物。
-- 当前版本是否已有签名 Manifest 缓存。脚本会优先从当前用户数据目录读取：
-  `$XDG_DATA_HOME/Marsco/UpdateClientSDK/installations/<安装目录SHA256>/update/manifest_cache`，
-  未设置 `XDG_DATA_HOME` 时通常是 `~/.local/share/Marsco/UpdateClientSDK/installations/<安装目录SHA256>/update/manifest_cache`。
-  同时兼容旧版 Release 目录里的 `update/manifest_cache`。
-- 是否存在重复主程序。
-
-Linux 下如果程序安装在 `/opt`、`/usr/local` 等普通用户不可写目录，升级器无法像 Windows UAC 那样自动提权修改安装目录。正式部署前建议二选一：
-
-1. 把软件安装到当前用户有写权限的目录，例如用户 home 下的应用目录。
-2. 由安装器创建专用目录和权限，让运行用户对软件目录有写入权限。
-
-## 九、常见错误
-
-1. 直接启动业务主程序提示 ticket 错误：应从 `Launcher.exe` 启动。
-2. 首次启动保存配置/状态文件失败：如果目录不可写，SDK 会弹出管理员权限确认框；用户取消或当前账号没有管理员权限时仍会失败。
-3. 首次启动设备登记失败：检查编译进 qrc 的 `config/server_config.json`、`client_token`、`license_key`、服务端 License 状态。
-4. 提示 License 错误或过期：在后台确认 License 是否存在、是否被禁用或删除、是否超过最大设备数。
-5. 策略或 Manifest 验签失败：检查 `config/manifest_public_key.pem` 是否和服务端私钥匹配。
-6. 提示 signed manifest cache missing：先在后台发布一次 `current_version` 对应版本，并让客户端拿到该版本 Manifest。
-7. 升级后回滚：检查业务程序是否在 `health_check_timeout_ms` 内写入健康标记。
-8. 发布失败提示主程序不在根目录：服务端 `.env` 中 `RELEASE_MAIN_EXECUTABLE` 要和平台匹配。Windows 通常是 `bin/SimCAE.exe`；Linux 通常是 `bin/SimCAE`。
-9. 启动时提示 `无法定位程序输入点 ... Qt5*.dll`：通常是 Qt DLL 被不同版本覆盖或混用。恢复业务软件原始 Qt DLL，并重新打包 SDK；SimCAE 场景下不要使用 `-IncludeQtRuntime`。

-# 客户端编译环境和第三方依赖说明
-
-`thirdparty/` 是本机依赖目录，已经被 `.gitignore` 忽略，不会提交到 Git。
-
-当前客户端构建依赖：
-
-1. Qt 5.15.2 或兼容的 Qt 5 版本
-2. OpenSSL
-
-Windows 下推荐使用 Qt 5.15.2 msvc2019_64 和 OpenSSL-Win64；Linux 下使用系统安装的 Qt/OpenSSL 开发包。
-
-先看结论：
-
-- Windows：配置 Qt 环境变量，把 OpenSSL 复制到 `thirdparty/OpenSSL-Win64`。
-- Linux：用 apt 安装 Qt/OpenSSL 开发包。
-- `thirdparty/` 只放本机依赖，不提交 Git。
-
-## 1. Qt 配置
-
-### Windows
-
-Qt 路径由本机环境变量提供。你需要在 Windows 环境变量里配置 Qt 路径，让 CMake 的 `find_package(Qt5 ...)` 能找到 Qt。
-
-推荐配置用户环境变量 `CMAKE_PREFIX_PATH`：
-
-```powershell
-[Environment]::SetEnvironmentVariable("CMAKE_PREFIX_PATH", "C:\Qt\5.15.2\msvc2019_64", "User")
-```
-
-设置完成后，重新打开 PowerShell 或 Visual Studio。
-
-如果只想对当前 PowerShell 窗口临时生效：
-
-```powershell
-$env:CMAKE_PREFIX_PATH="C:\Qt\5.15.2\msvc2019_64"
-```
-
-也可以配置更精确的 `Qt5_DIR`：
-
-```powershell
-[Environment]::SetEnvironmentVariable("Qt5_DIR", "C:\Qt\5.15.2\msvc2019_64\lib\cmake\Qt5", "User")
-```
-
-`CMAKE_PREFIX_PATH` 和 `Qt5_DIR` 二选一即可，推荐使用 `CMAKE_PREFIX_PATH`。
-
-一般不需要把 `C:\Qt\5.15.2\msvc2019_64\bin` 加入 `Path`。项目构建后会通过 `windeployqt` 复制运行所需的 Qt DLL。
-
-### Linux
-
-Linux 下需要安装 Qt5 开发包，让 CMake 能找到 `Qt5::Core`、`Qt5::Network`、`Qt5::Gui`、`Qt5::Widgets`。
-
-Ubuntu/Debian 示例：
-
-```bash
-sudo apt update
-sudo apt install -y build-essential cmake qtbase5-dev qttools5-dev-tools libssl-dev
-```
-
-如果 Qt 安装在自定义目录，可以临时设置：
-
-```bash
-export CMAKE_PREFIX_PATH=/path/to/Qt/5.x/gcc_64
-```
-
-## 2. OpenSSL 配置
-
-### Windows
-
-OpenSSL 默认放在：
-
-```text
-thirdparty/OpenSSL-Win64
-```
-
-推荐目录结构：
-
-```text
-thirdparty/
-  OpenSSL-Win64/
-    include/
-      openssl/
-    lib/
-      VC/
-        x64/
-          MD/
-          MDd/
-```
-
-复制命令示例：
-
-```powershell
-cd C:\Users\admin\Desktop\update-client
-mkdir thirdparty
-Copy-Item "C:\Program Files\OpenSSL-Win64" ".\thirdparty\OpenSSL-Win64" -Recurse
-```
-
-如果 OpenSSL 不放在 `thirdparty/`，可以在配置 CMake 时手动指定：
-
-```powershell
-cmake -S . -B out\build\x64-Debug `
-  -G "Visual Studio 17 2022" `
-  -A x64 `
-  -DSIMCAE_OPENSSL_ROOT="C:\Program Files\OpenSSL-Win64"
-```
-
-### Linux
-
-Linux 下 CMake 会通过 `find_package(OpenSSL REQUIRED)` 查找系统 OpenSSL。通常安装 `libssl-dev` 即可，不需要 `thirdparty/OpenSSL-Win64`。
-
-## 3. Windows 重新配置和编译
-
-如果之前配置过 CMake，建议先删除旧缓存：
-
-```powershell
-cd C:\Users\admin\Desktop\update-client
-Remove-Item out\build -Recurse -Force
-```
-
-重新配置：
-
-```powershell
-cmake -S . -B out\build\x64-Debug `
-  -G "Visual Studio 17 2022" `
-  -A x64
-```
-
-编译：
-
-```powershell
-cmake --build out\build\x64-Debug --config Debug
-```
-
-## 4. Linux 重新配置和编译
-
-如果之前配置过 CMake，建议先删除旧缓存：
-
-```bash
-cd ~/project/update-client
-rm -rf out/build/linux-x64-debug out/build/linux-x64-release
-```
-
-Debug 构建：
-
-```bash
-cmake --preset linux-x64-debug
-cmake --build --preset linux-x64-debug
-```
-
-Release 构建：
-
-```bash
-cmake --preset linux-x64-release
-cmake --build --preset linux-x64-release
-```
-
-Linux 构建时会自动使用 `config/app_config.linux.example.json` 作为输出目录里的默认 `config/app_config.json`，可执行程序名不带 `.exe`。
-
-## 5. 提交注意事项
-
-不要提交下面这些内容：
-
-```text
-thirdparty/
-.vs/
-out/
-build/
-dist/
-App/
-*.exe
-*.dll
-*.lib
-*.pdb
-```
-
-这些都属于本机依赖、构建产物或打包产物，不应该进 Git。

+# SimCAE Hub 更新客户端
+
+`update-client` 是 SimCAE Hub 的 Qt/C++ 整包更新客户端，包含 `Launcher`、`Updater`、`Bootstrap` 和一个示例 `MainApp`。它负责检查整包更新、拉取 Manifest、下载发布包、校验哈希并完成本地安装。
+
+组件级安装、组件级更新和卸载由 Qt IFW 生成的 `maintenancetool.exe` 负责。`update-client` 不替代 MaintenanceTool，也不读取 Qt IFW 的 `Updates.xml`。
+
+## 一、当前接入方式
+
+当前 SIMCAE 的标准接入方式是：
+
+| 阶段 | 发生什么 |
+| --- | --- |
+| SDK 打包 | `update-client` 只打出 `Launcher.exe`、`Updater.exe`、`Bootstrap.exe` 和运行库 |
+| SIMCAE 打包 | SIMCAE 的 `installer` 规则把 SDK 文件放进核心组件 `com.simcae.app` |
+| 本地 IFW package | Hub 更新客户端位于 `package/packages/com.simcae.app/data/view/bin` |
+| 上传到 Hub | 服务端校验 IFW 交付包，并自动注入最终客户配置 |
+| 客户安装 | 客户从门户下载安装器，安装后得到 `maintenancetool.exe` 和 `view/bin/Launcher.exe` |
+| 日常启动 | 客户通过 `Launcher.exe` 或安装器创建的快捷方式启动 SimCAE |
+
+最终客户不需要手动填写 `app_config.json`、服务器地址、token、产品编码、平台架构或版本号。
+
+## 二、程序组成
+
+| 程序 | 作用 |
+| --- | --- |
+| `Launcher` | 客户日常启动入口，读取配置、检查整包更新、启动 `Updater` 或主程序 |
+| `Updater` | 拉取 Manifest、下载发布包、校验文件、准备安装事务 |
+| `Bootstrap` | 替换运行中文件，并把安装结果交回 `Updater` |
+| `MainApp` | 示例主程序，用于验证 launch ticket 和启动前完整性校验 |
+| `Common` | 配置、HTTP、票据、路径、Manifest 和完整性校验等公共代码 |
+
+真实接入 SIMCAE 时，`MainApp` 只是示例程序。正式主程序是 SIMCAE 自己的 `SimCAE.exe`。
+
+## 三、在线更新链路
+
+1. 客户启动 `Launcher.exe`。
+2. 客户端读取服务端注入的初始配置。
+3. 首次启动时，客户端会把 `app_config.json` 中的运行配置导入本机用户配置。
+4. 为减少明文配置暴露，导入成功后客户端可能清空安装目录里的 `app_config.json`。
+5. `Launcher` 确保本机有 `device_id`。
+6. `Launcher` 使用 `X-Client-Token` 调用更新检查接口。
+7. 如果服务端返回可用发布，`Launcher` 启动 `Updater`。
+8. `Updater` 使用 `X-Client-Token` 拉取 Manifest。
+9. `Updater` 校验 Manifest 摘要，并按配置决定是否要求签名。
+10. `Updater` 按 Manifest 下载文件。
+11. 每个文件下载完成后校验大小和 SHA-256。
+12. 安装前校验 staging 目录。
+13. 如需替换运行中文件，`Bootstrap` 接管安装。
+14. 安装完成后保存 Manifest 缓存和本地状态。
+15. 如果主程序开启启动前完整性校验，下次启动时会按本地 Manifest 缓存校验已安装文件。
+
+更新接口使用部署级 `client_token`，不使用客户邮箱密码。客户账号和授权主要控制门户下载、客户权益和席位，不要求最终客户启动软件时再登录。
+
+## 四、当前 SIMCAE 目录规则
+
+客户安装完成后的关键目录是：
+
+| 路径 | 说明 |
+| --- | --- |
+| `maintenancetool.exe` | Qt IFW 生成的组件维护工具，位于安装根目录 |
+| `components.xml` | Qt IFW 记录的已安装组件状态，位于安装根目录 |
+| `network.xml` | Qt IFW 记录的组件仓库地址，位于安装根目录 |
+| `view/bin/Launcher.exe` | Hub 更新客户端启动入口 |
+| `view/bin/Updater.exe` | Hub 整包更新程序 |
+| `view/bin/Bootstrap.exe` | Hub 安装接管程序 |
+| `view/bin/SimCAE.exe` | SIMCAE 业务主程序 |
+| `view/bin/config/app_config.json` | 服务端注入的初始客户配置 |
+
+当前服务端会识别三种运行目录：
+
+| 运行目录 | 服务端写入的 `install_root` | 说明 |
+| --- | --- | --- |
+| 软件根目录 | `.` | `Launcher` 和主程序就在软件根目录 |
+| `bin` | `..` | `Launcher` 在一层 `bin` 目录中 |
+| `view/bin` | `../..` | 当前 SIMCAE 标准结构，`Launcher` 在 `view/bin` 中 |
+
+`install_root` 不是让客户手动填写的字段。上传发布包或 Qt IFW 交付包时，服务端会根据 `Launcher`、`Updater`、`Bootstrap` 的实际位置自动判断。
+
+## 五、服务端注入的配置
+
+正式客户包中的 `app_config.json` 由服务端生成或替换。开发者打 SDK 时不放最终配置，客户也不手动改配置。
+
+服务端生成配置时，信息来源如下：
+
+| 配置内容 | 来源 |
+| --- | --- |
+| `product_code`、`app_id` | 管理后台“产品目录”的产品编码 |
+| `app_name` | 管理后台“产品目录”的产品名称 |
+| `channel` | 管理后台“软件发布”的发布通道 |
+| `current_version` | 管理后台“产品版本”的版本号 |
+| `platform`、`arch`、`abi` | 管理后台“平台管理”和发布包选择的平台 |
+| `api_base_url` | 服务端 `.env` 的 `SIMCAE_CLIENT_API_BASE_URL` |
+| `client_token` | 服务端 `.env` 的 `SIMCAE_CLIENT_TOKEN` |
+| `launch_token` | 服务端 `.env` 的 `SIMCAE_LAUNCH_TOKEN` |
+| `install_root` | 服务端根据运行目录自动判断 |
+| `main_executable` | 服务端在运行目录中识别到的业务主程序，SIMCAE 当前为 `SimCAE.exe` |
+| `launcher_executable` | 按平台生成，Windows 为 `Launcher.exe` |
+| `updater_executable` | 按平台生成，Windows 为 `Updater.exe` |
+| `bootstrap_executable` | 按平台生成，Windows 为 `Bootstrap.exe` |
+| `require_manifest_signature` | 服务端 Manifest 签名配置 |
+| `verify_installed_on_start` | 当前服务端默认写入 `false`，需要强制启动校验时再按发布策略开启 |
+
+如果上传包里已经带了旧的 `app_config.json`、`server_config.json`、`server_config.qrc` 或 `manifest_public_key.pem`，服务端会按当前发布信息重新处理，不让开发机临时配置直接进入最终客户包。
+
+## 六、本地调试配置
+
+正式发布不要手写最终 `app_config.json`。如果开发者只是在本机调试 `Launcher` 或 `Updater`，可以创建未提交的 `config/app_config.local.json`。
+
+CMake 只在本地输出目录还没有 `config/app_config.json` 时，才会把 `app_config.local.json` 复制成调试用配置。这个文件只服务本机调试，不代表服务端最终注入结果。
+
+`config/server_config.json` 和 `config/server_config.qrc` 用于把兜底 API 地址编译进 EXE。正式客户包优先使用服务端注入的 `api_base_url`，一般不需要让客户看到或修改 `server_config.json`。
+
+## 七、启动门禁
+
+如果 SIMCAE 主程序开启 `SimCAE_UseLauncher=ON`，用户直接双击 `SimCAE.exe` 会被拦截，必须通过 `Launcher.exe` 启动。
+
+这套机制依赖 `launch_token`：
+
+| 位置 | 要求 |
+| --- | --- |
+| 服务端 `.env` | 必须配置 `SIMCAE_LAUNCH_TOKEN` |
+| SIMCAE 编译期 | 主程序编译时使用同一个 token |
+| 客户端配置 | 服务端把同一个 token 写入最终客户配置 |
+
+如果三处 token 不一致，就会出现“直接双击被拦住，但从 `Launcher` 启动也失败”的问题。
+
+## 八、Manifest 和哈希校验
+
+整包更新使用 SimCAE Hub Manifest，不使用 Qt IFW 的 `Updates.xml`。
+
+Manifest 负责描述：
+
+| 内容 | 说明 |
+| --- | --- |
+| 发布版本 | 本次更新属于哪个产品、版本线、版本和通道 |
+| 文件清单 | 本次发布包含哪些文件 |
+| 下载地址 | 每个文件从哪个受控接口下载 |
+| 文件大小 | 客户端下载后必须一致 |
+| SHA-256 | 客户端下载后必须一致 |
+| 是否必选 | 必选文件缺失会阻止启动，可选组件文件可由 MaintenanceTool 管理 |
+
+服务端返回 Manifest 前会重新检查发布包文件是否存在、大小是否一致、SHA-256 是否一致。客户端下载完成后也会再次校验大小和 SHA-256。
+
+## 九、和 MaintenanceTool 的边界
+
+| 能力 | 使用程序 | 文件格式 |
+| --- | --- | --- |
+| 整包更新 | `Launcher`、`Updater`、`Bootstrap` | SimCAE Hub 发布包和 Manifest |
+| 组件安装、更新、移除 | `maintenancetool.exe` | Qt IFW repository 和 `Updates.xml` |
+
+两条线可以共存，但不要混淆：
+
+1. `Updater` 不读取 `Updates.xml`。
+2. `MaintenanceTool` 不读取 SimCAE Hub Manifest。
+3. `Updater` 不拉起 `MaintenanceTool`。
+4. `MaintenanceTool` 由客户手动打开，或由 Qt IFW 自己的流程使用。
+5. 核心组件通常包含 `Launcher`、`Updater`、`Bootstrap` 和 `SimCAE.exe`。
+6. 可选组件例如 DAP 插件，可以由 MaintenanceTool 单独安装、更新或移除。
+
+## 十、编译环境
+
+| 依赖 | 要求 |
+| --- | --- |
+| CMake | 建议 3.20 或更高版本 |
+| C++ | C++17 |
+| Qt | Qt 5，至少需要 Core、Network、Gui、Widgets |
+| OpenSSL | 用于 Manifest RSA-SHA256 验签 |
+| 编译器 | Windows 推荐 Visual Studio 2022 x64，Linux 推荐 gcc/g++ |
+
+项目提供的 CMake Preset：
+
+| Preset | 平台 | 用途 |
+| --- | --- | --- |
+| `x64-debug` | Windows | Debug 编译 |
+| `x64-release` | Windows | Release 编译 |
+| `linux-x64-debug` | Linux | Debug 编译 |
+| `linux-x64-release` | Linux | Release 编译 |
+
+## 十一、Windows 编译
+
+建议安装 Visual Studio 2022、Qt 5 x64、CMake 和 OpenSSL x64。
+
+如果 Qt 没有加入环境变量，可以在编译前指定：
+
+```powershell
+$env:CMAKE_PREFIX_PATH = "C:\Qt\5.15.2\msvc2019_64"
+```
+
+当前测试机 OpenSSL 路径是 `C:\Program Files\OpenSSL-Win64`，Release 编译命令：
+
+```powershell
+cmake --preset x64-release -DSIMCAE_OPENSSL_ROOT="C:\Program Files\OpenSSL-Win64"
+cmake --build --preset x64-release
+```
+
+如果 OpenSSL 安装在其他目录，只改 `SIMCAE_OPENSSL_ROOT` 这一项。
+
+Windows Release 产物通常输出到 `out/bin/Release`。
+
+检查核心程序：
+
+```powershell
+Test-Path .\out\bin\Release\Launcher.exe
+Test-Path .\out\bin\Release\Updater.exe
+Test-Path .\out\bin\Release\Bootstrap.exe
+```
+
+预期都返回 `True`。
+
+## 十二、Linux 编译
+
+Ubuntu 示例：
+
+```bash
+sudo apt update
+sudo apt install -y build-essential cmake qtbase5-dev qttools5-dev qttools5-dev-tools libssl-dev
+cmake --preset linux-x64-release
+cmake --build --preset linux-x64-release
+```
+
+Linux 下通常直接使用系统 OpenSSL；如果需要指定自定义 OpenSSL，也可以通过 CMake 变量配置。
+
+## 十三、打包 SDK
+
+SDK 打包流程见当前目录 [updater打包成SDK.md](updater打包成SDK.md)。SIMCAE 拿到 SDK 后的安装器、交付包和上传流程见 [SIMCAE打包上传.md](SIMCAE打包上传.md)。
+
+常用输出：
+
+| 输出 | 说明 |
+| --- | --- |
+| `dist\UpdateClientSDK` | 不带 Qt 运行库的 SDK 展开目录 |
+| `dist\UpdateClientSDK.zip` | 不带 Qt 运行库的 SDK 压缩包 |
+| `dist\UpdateClientSDK-With-QtDll` | 带 Qt 运行库 DLL 的 SDK 展开目录 |
+| `dist\UpdateClientSDK-With-QtDll.zip` | 推荐交给 SIMCAE 开发者的 SDK 压缩包 |
+
+SDK 不包含最终客户配置。`With-QtDll` 表示包里带的是运行所需的 Qt DLL，不是完整 Qt SDK。SDK 的目标是给 SIMCAE 打包流程提供更新客户端程序和运行库。
+
+## 十四、运行数据位置
+
+Windows 运行配置会导入当前用户配置，按安装运行目录计算 installation id。运行数据目录通常位于：
+
+`%LOCALAPPDATA%\SimCAE\HubUpdateClient\installations\<安装目录SHA256>\`
+
+Linux 运行数据目录通常位于：
+
+`$XDG_DATA_HOME/SimCAE/HubUpdateClient/installations/<安装目录SHA256>/`
+
+未设置 `XDG_DATA_HOME` 时通常是：
+
+`~/.local/share/SimCAE/HubUpdateClient/installations/<安装目录SHA256>/`
+
+Manifest 缓存保存在运行数据目录下的 `update/manifest_cache`。
+
+## 十五、常见问题
+
+| 现象 | 排查方向 |
+| --- | --- |
+| 客户启动后提示配置不完整 | 检查交付包是否经过 SimCAE Hub 上传注入，不要直接拿本地未注入包给客户 |
+| 检查更新没有结果 | 检查后台发布是否已发布、发布包是否可用、产品编码、通道和平台是否一致 |
+| 下载返回 401 | 检查客户包里的 `client_token` 是否来自当前服务端 `.env` |
+| Manifest 校验失败 | 检查服务端文件是否被手工改过，大小和 SHA-256 是否与数据库一致 |
+| 强制签名失败 | 检查 `manifest_public_key.pem` 与服务端私钥是否匹配 |
+| 主程序启动失败 | 检查 `main_executable` 和运行目录是否正确 |
+| 从 `Launcher` 启动也被拦截 | 检查服务端、SIMCAE 编译期和客户配置中的 `launch_token` 是否一致 |
+| MaintenanceTool 看不到组件更新 | 检查 IFW repository 地址、`Updates.xml` 和组件版本是否正确 |

+# SIMCAE 打包上传
+
+本文站在 SIMCAE 开发者和发布人员的角度，说明拿到 Hub 更新客户端 SDK 后，SIMCAE 怎么打安装器、怎么生成 Qt IFW 交付包、怎么上传到 SimCAE Hub。
+
+服务端部署流程见 simcae-hub 项目根目录《服务端部署.md》。普通发布人员只需要拿到已经打好的更新客户端 SDK；如果需要重新生成 SDK，见源代码仓库 `SIMCAE/update-client/updater打包成SDK.md`。
+
+本文下面的命令默认在 SIMCAE 项目根目录执行。下面用 SIMCAE 当前放在 simcae-hub 项目里的情况举例：
+
+```powershell
+cd .\SIMCAE
+```
+
+进入后再使用相对路径，例如 `.\installer`、`.\update-client`、`.\out\build\...`。这样不要求开发者的 SIMCAE 一定放在某个固定磁盘目录。
+
+## 一、先理解交付物
+
+客户端交付会涉及三类文件：
+
+| 交付物 | 给谁用 | 作用 |
+| --- | --- | --- |
+| Hub 更新客户端 SDK | SIMCAE 开发者 | 提供 `Launcher.exe`、`Updater.exe`、`Bootstrap.exe` 和必要运行库 |
+| Qt IFW 交付包 ZIP | 上传到 SimCAE Hub | 包含 IFW package 和 repository，服务端会校验、注入配置、发布仓库并重新生成客户安装器 |
+| 客户安装器 | 最终客户 | 客户从门户下载后双击安装，安装后得到 `maintenancetool.exe` |
+
+正式主线是：开发者只上传一个 Qt IFW 交付包 ZIP，客户只从门户下载客户安装器。客户不需要手动改服务器地址、token 或 `app_config.json`。
+
+## 二、准备 Hub 更新客户端 SDK
+
+开发者应拿到 `UpdateClientSDK-With-QtDll.zip`。
+
+这个 ZIP 由 `update-client` 仓库的 SDK 打包脚本生成，SDK 维护者按源代码仓库 `SIMCAE/update-client/updater打包成SDK.md` 操作即可。
+
+建议手动解压到 SIMCAE 仓库内的固定相对目录：`.\update-client\dist\UpdateClientSDK-With-QtDll`。
+
+这里的 `With-QtDll` 表示包里带的是运行所需的 Qt DLL，不是完整 Qt SDK。
+
+如果公司内部统一把 SDK 放在别的位置，也可以，只要后面 `$UpdateClientSdk` 指向解压后的 SDK 目录即可。
+
+解压后至少应有：
+
+- `bin\Launcher.exe`
+- `bin\Updater.exe`
+- `bin\Bootstrap.exe`
+
+SDK 包不应该包含最终客户配置，例如 `app_config.json`、`server_config.json`、`server_config.qrc`、`manifest_public_key.pem`。这些最终配置由服务端在上传发布包时生成或注入。
+
+## 三、准备 SIMCAE 已编译产物
+
+默认 SIMCAE 已经在开发机上完成 Release 编译。客户端打包文档不要求每次重新全量编译 SIMCAE，因为 SIMCAE 工程很大，打安装包时通常只需要复用已有 Release 产物。
+
+需要确认：
+
+| 内容 | 说明 |
+| --- | --- |
+| SIMCAE Release 构建目录 | 已经存在 `SimCAE.exe`、库文件、资源文件 |
+| Qt Installer Framework | 已经安装 `binarycreator.exe` 和 `repogen.exe` |
+| DAP 运行时 | 如果启用 DAP 组件，`DAPrailCalxml` 等运行时已放在打包规则要求的位置 |
+| Hub 更新客户端 SDK | 已解压，并能找到 `Launcher.exe`、`Updater.exe`、`Bootstrap.exe` |
+
+如果业务主程序启用了“必须从 Launcher 启动”的门禁，SIMCAE 编译时使用的 launch token 必须和服务端 `.env` 里的 `SIMCAE_LAUNCH_TOKEN` 一致。
+
+## 四、设置本次打包版本
+
+SIMCAE 安装器文件名、IFW 组件 `package.xml` 版本、repository 里的 `Updates.xml` 版本都来自 CMake 变量 `SimCAE_Version`。这个版本默认读取 SIMCAE 仓库最近的纯数字 Git tag，例如 `1.1.3`。
+
+先把几个容易混淆的“版本标签”分清楚：
+
+| 名称 | 写在哪里 | 谁会读取 | 作用 |
+| --- | --- | --- | --- |
+| Git tag | SIMCAE 仓库提交，例如 `git tag 1.1.3` | CMake 版本脚本 | 生成 `SimCAE_Version`，再写入安装器文件名和组件元数据 |
+| 组件版本 | `packages/<组件ID>/meta/package.xml` 的 `<Version>` | `repogen.exe` | 生成 repository 时写入 `Updates.xml` |
+| repository 组件版本 | `Updates.xml` 里的 `<PackageUpdate><Name>...` 和 `<Version>...` | `maintenancetool.exe` | 客户端判断某个组件是否需要更新 |
+| ZIP 文件名 | 例如 `SimCAE-Delivery-1.1.3-windows_x86_64-msvc.zip` | 人和管理后台记录 | 方便识别上传文件，不是 MaintenanceTool 的更新依据 |
+
+所以 `git tag 1.1.3` 打的是 SIMCAE 源码提交标签，不是给 ZIP 文件打标签。它会被 CMake 读取后间接变成组件 `package.xml` 里的版本。真正决定 MaintenanceTool 是否更新的是服务器 repository 的 `Updates.xml`，而 `Updates.xml` 又来自组件自己的 `package.xml`。
+
+正式发布时推荐在 SIMCAE 仓库给本次发布提交打纯数字 tag，再打包：
+
+```powershell
+git tag 1.1.3
+```
+
+如果只是本机演示，不想改 SIMCAE 仓库 tag，可以临时指定本次打包版本。下面命令会创建一个本地临时脚本，让 CMake 本次配置时读到 `1.1.3`：
+
+```powershell
+$Version = "1.1.3"
+$GitVersionShim = "..\.tmp\git-version-$Version.cmd"
+New-Item -ItemType Directory -Force (Split-Path $GitVersionShim) | Out-Null
+
+@"
+@echo off
+if /I "%1"=="describe" (
+  echo $Version
+  exit /b 0
+)
+git %*
+"@ | Set-Content -LiteralPath $GitVersionShim -Encoding ASCII
+```
+
+后续所有命令都复用这个 `$Version`。不要只改 ZIP 文件名，否则会出现文件名是 `1.1.3`，但组件 `package.xml` 和 `Updates.xml` 里版本还是 `0.10.1` 的错包；这种包上传后，MaintenanceTool 仍然会按 `0.10.1` 判断。
+
+## 五、刷新现有 CMake 打包配置
+
+下面命令只刷新已有构建目录的 CMake 配置，用来告诉打包目标 Qt IFW 在哪里，以及 Hub 更新客户端的本地编译产物和 SDK 兜底在哪里，不是全量重新编译 SIMCAE。
+
+先确认当前 PowerShell 已经在 SIMCAE 项目根目录。下面给出一个常见 Qt IFW 安装路径示例；如果你的 Qt IFW 装在别的位置，只改 `$QtIfwRoot` 这一行。
+
+```powershell
+$Build = ".\out\build\SimCAE-release-vs2022-qt515-ifw"
+$QtIfwRoot = "C:\Qt\Tools\QtInstallerFramework\4.11"
+$HubUpdateClientRuntime = ".\update-client\out\bin\Release"
+$UpdateClientSdk = ".\update-client\dist\UpdateClientSDK-With-QtDll"
+```
+
+先检查 SIMCAE 工程里的 Hub 更新客户端本地编译产物：
+
+```powershell
+Test-Path "$QtIfwRoot\bin\binarycreator.exe"
+Test-Path "$QtIfwRoot\bin\repogen.exe"
+Test-Path "$HubUpdateClientRuntime\Launcher.exe"
+Test-Path "$HubUpdateClientRuntime\Updater.exe"
+Test-Path "$HubUpdateClientRuntime\Bootstrap.exe"
+```
+
+如果上面三个 EXE 都存在，打 SIMCAE 安装包时会优先使用它们，不会再从 SDK 目录重复拿一份。
+
+如果本地编译产物不存在，再检查 SDK 兜底目录：
+
+```powershell
+Test-Path "$UpdateClientSdk\bin\Launcher.exe"
+Test-Path "$UpdateClientSdk\bin\Updater.exe"
+Test-Path "$UpdateClientSdk\bin\Bootstrap.exe"
+```
+
+如果本次要让 `SimCAE.exe` 只能从 `Launcher.exe` 启动，先准备 SIMCAE 编译期使用的本地打包配置。这里的 `launch_token` 必须和服务端 `.env` 里的 `SIMCAE_LAUNCH_TOKEN` 完全一致。
+
+```powershell
+$LauncherProductConfig = "..\.tmp\simcae-launcher-product-config.json"
+
+@'
+{
+  "app_id": "simcae",
+  "product_code": "simcae",
+  "app_name": "SimCAE",
+  "launch_token": "SimCAE_Launch_Token_2026_ChangeMe_32Bytes",
+  "license_key": "SIMCAE_LOCAL_PACKAGING_LICENSE_2026"
+}
+'@ | Set-Content -LiteralPath $LauncherProductConfig -Encoding UTF8
+```
+
+刷新配置：
+
+```powershell
+cmake -S . -B $Build `
+  "-DSimCAE_QtIfwRoot=$QtIfwRoot" `
+  "-DSimCAE_PackageHubUpdateClient=ON" `
+  "-DSimCAE_HubUpdateClientRuntimeDir=$HubUpdateClientRuntime" `
+  "-DSimCAE_HubUpdateClientSdkDir=$UpdateClientSdk" `
+  "-DSimCAE_UseLauncher=ON" `
+  "-DSimCAE_LauncherProductConfigFile=$LauncherProductConfig" `
+  "-DGIT_EXECUTABLE=$GitVersionShim"
+```
+
+`SimCAE_PackageHubUpdateClient=ON` 只负责把 `Launcher.exe`、`Updater.exe`、`Bootstrap.exe` 放进 SIMCAE 安装包。正式客户配置文件，例如 `config/app_config.json` 和 `config/manifest_public_key.pem`，仍然由服务端在上传发布包时生成或注入，不从开发机本地目录带进最终客户包。
+
+如果只想把 Hub 更新客户端打进安装包，但暂时不限制用户直接双击 `SimCAE.exe`，则把上面命令中的 `SimCAE_UseLauncher` 改为 `OFF`，并去掉 `SimCAE_LauncherProductConfigFile` 这一项。
+
+## 六、生成客户安装器和 IFW package
+
+执行打包目标：
+
+```powershell
+cmake --build $Build --config Release --target package_installer
+```
+
+这个目标会读取 `SIMCAE\installer` 下的配置和组件规则，整理 IFW package staging，并生成安装器。组件有哪些、每个组件包含哪些文件、组件是否必选、依赖哪些组件，应该由 SIMCAE 开发者在打包配置和 `package.xml.in` 里提前定义好；SimCAE Hub 不会自动猜测业务应该拆成哪些组件。
+
+当前示例里已有两个 IFW 组件：
+
+| 组件目录 | 组件含义 | 元数据来源 |
+| --- | --- | --- |
+| `packages/com.simcae.app` | 核心程序、Launcher、Updater、Bootstrap、核心库和通用资源 | `installer/packages/meta/package.xml.in` |
+| `packages/com.simcae.dap` | DAP 求解器插件及运行资源 | `installer/packages/com.simcae.dap/meta/package.xml.in` |
+
+Qt IFW 的组件 ID 来自 `packages/<组件ID>` 目录名，例如 `com.simcae.dap`。组件显示名称、版本、是否强制安装、依赖关系等来自该组件的 `meta/package.xml`，例如 `<DisplayName>`、`<Version>`、`<ForcedInstallation>`、`<Dependencies>`。
+
+常见输出：
+
+| 输出 | 说明 |
+| --- | --- |
+| `$Build\package` | Qt IFW package staging 目录 |
+| `$Build\SimCAE-<版本>-Windows-installer.exe` | 本地生成的客户安装器 |
+
+确认核心组件里已经带上 Hub 更新客户端：
+
+```powershell
+Test-Path "$Build\package\packages\com.simcae.app\data\view\bin\Launcher.exe"
+Test-Path "$Build\package\packages\com.simcae.app\data\view\bin\Updater.exe"
+Test-Path "$Build\package\packages\com.simcae.app\data\view\bin\Bootstrap.exe"
+Test-Path "$Build\package\packages\com.simcae.app\data\view\bin\SimCAE.exe"
+```
+
+预期都返回 `True`。
+
+再确认 package 里的组件版本就是本次 `$Version`：
+
+```powershell
+$AppPackageXml = "$Build\package\packages\com.simcae.app\meta\package.xml"
+$DapPackageXml = "$Build\package\packages\com.simcae.dap\meta\package.xml"
+$AppVersion = ([xml](Get-Content -LiteralPath $AppPackageXml -Encoding UTF8 -Raw)).Package.Version
+$DapVersion = ([xml](Get-Content -LiteralPath $DapPackageXml -Encoding UTF8 -Raw)).Package.Version
+
+if ($AppVersion -ne $Version -or $DapVersion -ne $Version) {
+  throw "组件版本不一致：app=$AppVersion dap=$DapVersion expected=$Version"
+}
+
+Test-Path "$Build\SimCAE-$Version-Windows-installer.exe"
+```
+
+最后一行预期返回 `True`。如果这里不是 `True`，不要继续生成 repository。
+
+## 七、生成 IFW repository
+
+MaintenanceTool 读取的是 Qt IFW repository，不是客户安装器。
+
+生成前先确认 `$Build\package` 已经存在，并且里面至少有 `config` 和 `packages`：
+
+```powershell
+Test-Path "$Build\package\config\config.xml"
+Test-Path "$Build\package\packages"
+```
+
+预期都返回 `True`。然后生成完整 repository：
+
+```powershell
+powershell -NoProfile -ExecutionPolicy Bypass -File ".\installer\scripts\build-ifw-repository.ps1" `
+  -PackageDir "$Build\package" `
+  -OutputDir "$Build\ifw-repository" `
+  -ZipFile "$Build\SimCAE-IFW-Repository-$Version-windows_x86_64-msvc.zip"
+```
+
+这条命令不是“给压缩包打版本标签”。它只是调用 Qt IFW 的 `repogen.exe`，从 `$Build\package\packages` 读取已经准备好的组件目录和 `meta/package.xml`，生成 `Updates.xml` 和组件 `.7z` 包，最后把 repository 目录压成 ZIP。ZIP 文件名里的 `$Version` 只是为了让发布人员识别文件。
+
+生成后检查：
+
+```powershell
+Test-Path "$Build\ifw-repository\Updates.xml"
+Select-String -LiteralPath "$Build\ifw-repository\Updates.xml" -Pattern "com.simcae.app|com.simcae.dap|<Version>"
+```
+
+生成的 repository 根目录必须包含 `Updates.xml`。这个 ZIP 一般不直接给客户，它是给 SimCAE Hub 后端托管，供 `maintenancetool.exe` 后续检查组件更新。
+
+确认 repository 里的组件版本也是本次 `$Version`：
+
+```powershell
+$UpdatesXml = "$Build\ifw-repository\Updates.xml"
+$UpdatesContent = Get-Content -LiteralPath $UpdatesXml -Encoding UTF8 -Raw
+
+if ($UpdatesContent -notmatch "<Version>$([regex]::Escape($Version))</Version>") {
+  throw "repository Updates.xml 中没有本次版本 $Version"
+}
+```
+
+## 八、组装 Qt IFW 交付包 ZIP
+
+推荐上传给 SimCAE Hub 的是交付包 ZIP，它把 package 和 repository 放在一起。客户安装器由服务端基于注入配置后的 package 重新生成。
+
+目录结构建议：
+
+- `package/config/`
+- `package/packages/com.simcae.app/`
+- `package/packages/com.simcae.dap/`
+- `repository/Updates.xml`
+- `repository/com.simcae.app/`
+- `repository/com.simcae.dap/`
+
+不要依赖交付包里的 `installer/SimCAE-<版本>-Windows-installer.exe` 作为最终客户安装器。本地生成的安装器没有服务端注入的 `app_config.json`，客户直接安装后 `Launcher.exe` 会缺少服务器地址、token 和主程序配置。服务端必须配置 `SIMCAE_IFW_BINARYCREATOR_PATH`，Linux 服务端生成 Windows 安装器时还必须配置 `SIMCAE_IFW_INSTALLERBASE_WINDOWS_PATH` 指向 Windows 版 `installerbase.exe`，上传后由服务端重新生成客户门户可下载的安装器。
+
+示例命令：
+
+```powershell
+$PlatformKey = "windows_x86_64-msvc"
+$Bundle = "$Build\SimCAE-Delivery-$Version-$PlatformKey"
+
+if (-not (Test-Path "$Build\ifw-repository\Updates.xml")) {
+  throw "缺少 repository/Updates.xml，请先生成 IFW repository"
+}
+
+Remove-Item -LiteralPath $Bundle -Recurse -Force -ErrorAction SilentlyContinue
+New-Item -ItemType Directory -Force "$Bundle" | Out-Null
+
+Copy-Item "$Build\package" "$Bundle\package" -Recurse -Force
+Copy-Item "$Build\ifw-repository" "$Bundle\repository" -Recurse -Force
+
+Compress-Archive -Path "$Bundle\*" -DestinationPath "$Build\SimCAE-Delivery-$Version-$PlatformKey.zip" -Force
+```
+
+`release.json` 不需要开发者手写。产品编码、产品名称、版本号、通道、平台、架构和 ABI 来自管理后台表单；运行目录和主程序名由服务端从核心组件中自动识别。
+
+## 九、上传到管理后台
+
+在浏览器打开管理后台，例如 `http://192.168.1.158:1798/login`。
+
+按左侧菜单顺序准备基础数据。第一次发布某个产品时要完整走一遍；后续同产品、同通道、同平台发布新版本时，只需要确认这些数据仍然存在：
+
+1. 产品目录：确认产品编码，例如 `simcae`。
+2. 版本线：确认通道或版本线，例如 `stable`。
+3. 组件管理：确认核心组件和可选组件，例如 `com.simcae.app`、`com.simcae.dap`；如果用于 MaintenanceTool 更新，后台组件编码要和 IFW package 的 `packages/<组件ID>` 目录名一致。
+4. 平台管理：确认 `windows`、`x86_64`、`msvc`。
+5. 产品版本：创建本次版本，例如 `1.1.3`。
+6. 软件发布：创建本次发布，关联产品版本和版本线。
+7. 发布包：新增或编辑发布包。
+
+上传完整 Qt IFW 交付包时，在“发布包”页面直接点击右上角新增发布包，不需要先点击某个软件卡片。这个入口只用于新建整包更新包和 Qt IFW 交付包。
+
+发布包页面选择：
+
+| 字段 | 建议 |
+| --- | --- |
+| 包类型 | Qt IFW 交付包 |
+| 文件 | `SimCAE-Delivery-<版本>-windows_x86_64-msvc.zip` |
+| 平台 | `windows / x86_64 / msvc` |
+| 状态 | 上传校验通过后变为可用 |
+
+操作顺序：
+
+1. 打开“发布包”页面。
+2. 直接点击右上角“新建发布包”。
+3. 包类型选择“Qt IFW 交付包”。此时普通新建入口只应看到“整包更新包”和“Qt IFW 交付包”。
+4. 文件名填写本次交付包文件名，例如 `SimCAE-Delivery-1.1.3-windows_x86_64-msvc.zip`。
+5. 选择产品、版本线、产品版本、发布和平台。
+6. 保存发布包记录。
+7. 点击该记录的“上传”。
+8. 选择本地生成的交付包 ZIP。
+9. 等待上传完成，状态应变为“可用”。
+
+上传成功后，服务端会：
+
+- 校验 ZIP 安全路径和 IFW 结构。
+- 校验 `package/` 和 `repository/Updates.xml`。
+- 读取组件清单和组件版本。
+- 自动注入 `config/app_config.json`。
+- 自动写入必要的公钥配置。
+- 发布 IFW repository。
+- 生成或登记客户门户首次下载的安装器。
+
+上传后建议立刻确认：
+
+```powershell
+$Base = "http://192.168.1.158:18000/api/v1/client/ifw/repositories/simcae/stable/windows_x86_64-msvc"
+(Invoke-WebRequest "$Base/Updates.xml" -UseBasicParsing).Content
+```
+
+预期能看到本次版本号、组件 ID 和组件名称。如果这里还是旧版本，先确认发布包状态是否为“可用”，再确认上传时选择的产品、通道和平台是否一致。
+
+## 十、客户下载和安装
+
+客户登录客户门户后，在下载中心下载客户安装器。客户下载到的是 `.exe` 安装器，不是 IFW repository ZIP，也不是开发者上传的交付包 ZIP。
+
+客户安装后，安装目录中应包含：
+
+- `maintenancetool.exe`
+- `components.xml`
+- `network.xml`
+- `view\bin\SimCAE.exe`
+- `view\bin\Launcher.exe`
+- `view\bin\Updater.exe`
+- `view\bin\Bootstrap.exe`
+- `view\bin\config\app_config.json`
+
+客户日常启动软件应使用 `Launcher.exe` 或安装器创建的快捷方式。组件更新、添加、移除由 `maintenancetool.exe` 负责。
+
+首次安装建议按这个顺序检查：
+
+1. 打开客户门户。
+2. 登录有授权的客户账号。
+3. 进入下载中心。
+4. 找到对应产品和版本。
+5. 点击下载，得到 `SimCAE-<版本>-Windows-installer.exe`。
+6. 双击安装器，按页面提示完成安装。
+7. 安装后进入安装目录，确认 `maintenancetool.exe`、`components.xml` 和 `view\bin\Launcher.exe` 都存在。
+8. 双击 `Launcher.exe`，预期能启动 SimCAE。
+9. 双击 `maintenancetool.exe`，预期能看到“添加或移除组件”“更新组件”“移除所有组件”。
+
+## 十一、组件更新
+
+这里的“组件”指 `maintenancetool.exe` 里能看到的 Qt IFW 组件，例如 `com.simcae.app`、`com.simcae.dap`。组件更新就是“只发布某些组件的新版本，或新增一个组件”，让客户后续通过 MaintenanceTool 更新；它不是客户首次安装用的安装器，也不是 Launcher / Updater 用的整包更新 ZIP。
+
+适合使用组件更新的情况：
+
+| 场景 | 应该怎么做 |
+| --- | --- |
+| 只更新 DAP 插件 | 做一个只包含 `com.simcae.dap` 的组件更新包 |
+| 新增示例、模板、插件等可选功能 | 做一个包含新组件的组件更新包 |
+| 一次更新几个互相依赖的组件 | 做一个多组件更新包，把这些组件一起放进去 |
+| 更新核心程序、Launcher、Updater、Bootstrap 或 `app_config.json` | 更推荐重新发完整 Qt IFW 交付包 |
+| 第一次发布某个产品、通道、平台 | 先发完整 Qt IFW 交付包，后面才能发组件更新 |
+
+组件更新包不是单独飘在系统外面的文件。它上传时必须挂到某个产品、某个产品版本、某次发布、某个平台下面。服务端会把它合并到这个产品对应通道和平台的 current repository 中。
+
+### 11.1 组件版本怎么定
+
+组件版本以组件自己的 `package.xml` 为准。比如 DAP 组件的版本写在这里：
+
+- `$Build\package\packages\com.simcae.dap\meta\package.xml`
+- XML 节点是 `<Version>1.1.4</Version>`
+
+如果说“组件标签”，这里真正参与更新判断的是组件 ID 和组件版本：组件 ID 来自目录名 `packages/com.simcae.dap`，组件版本来自 `meta/package.xml` 里的 `<Version>`。开发者在维护 IFW package 时就应该把组件拆分、显示名、版本、必选状态和依赖关系写清楚。`repogen.exe` 生成 repository 时，会把这些信息写进 `Updates.xml`。MaintenanceTool 也是根据 `Updates.xml` 里的组件版本判断是否可更新。
+
+当前 SIMCAE 全量打包默认会让所有组件跟随同一个 `$Version`，这个 `$Version` 来自 SIMCAE 仓库的纯数字 Git tag，或者前面文档里的 `$GitVersionShim` 临时版本脚本。例如 `$Version = "1.1.3"` 时，`com.simcae.app` 和 `com.simcae.dap` 默认都会变成 `1.1.3`。
+
+如果只更新 DAP，不更新核心组件，规则是：
+
+1. 服务器当前 `com.simcae.app` 是 `1.1.3`，`com.simcae.dap` 是 `1.1.3`。
+2. 本次只把 `com.simcae.dap` 的 `package.xml` 改成 `1.1.4`。
+3. 不改 `com.simcae.app` 的 `package.xml`，它仍然保持 `1.1.3`。
+4. 生成只包含 `com.simcae.dap` 的组件更新包。
+5. 上传后，服务器 current repository 里应变成 `com.simcae.app=1.1.3`、`com.simcae.dap=1.1.4`。
+
+正式流程里，建议 SIMCAE 打包侧给每个组件提供独立版本参数。当前如果只是本地演示，可以在 `$Build\package\packages\<组件ID>\meta\package.xml` 里调整目标组件的 `<Version>`，然后再生成组件更新包。不要改不更新的组件版本，也不要只改 ZIP 文件名。ZIP 名字里写了 `1.1.4`，但 `package.xml` 仍是 `1.1.3` 时，生成出来的 `Updates.xml` 也会是 `1.1.3`。
+
+### 11.2 先确认服务器已有当前仓库
+
+以 `simcae / stable / windows_x86_64-msvc` 为例：
+
+```powershell
+$Base = "http://192.168.1.158:18000/api/v1/client/ifw/repositories/simcae/stable/windows_x86_64-msvc"
+(Invoke-WebRequest "$Base/Updates.xml" -UseBasicParsing).Content
+```
+
+预期能看到当前仓库的组件，例如：
+
+- `<Name>com.simcae.app</Name>`
+- `<Version>1.1.3</Version>`
+- `<Name>com.simcae.dap</Name>`
+- `<Version>1.1.3</Version>`
+
+如果这里访问失败，先不要上传组件更新包，说明服务器还没有这个产品、通道、平台的 current repository。
+
+### 11.3 准备本地组件产物
+
+开发者先按 SIMCAE 自己的规则把组件文件准备到 IFW package staging 里。组件边界应该在开发和打包配置阶段就已经分好；后面的 repository 生成命令只是读取这些组件，不会自动分析文件并替开发者拆组件。当前打包目标会把组件整理到：
+
+- `$Build\package\packages\com.simcae.app`
+- `$Build\package\packages\com.simcae.dap`
+
+如果只更新 DAP 插件，先确认 DAP 组件目录存在：
+
+```powershell
+Test-Path "$Build\package\packages\com.simcae.dap\meta\package.xml"
+Test-Path "$Build\package\packages\com.simcae.dap\data"
+```
+
+预期都返回 `True`。同时要确认 `package.xml` 里的版本已经升高：
+
+```powershell
+Select-String -LiteralPath "$Build\package\packages\com.simcae.dap\meta\package.xml" -Pattern "<Version>"
+```
+
+例如服务器当前 DAP 是 `1.1.3`，本次 DAP 组件更新包应改成 `1.1.4` 或更高。
+
+### 11.4 生成组件更新 ZIP
+
+使用 `-Include` 只把要更新的组件打进 repository。`-Include "com.simcae.dap"` 里的值是组件 ID，也就是 `packages/com.simcae.dap` 这个目录名；它不是 ZIP 标签，也不是版本号。下面以只更新 DAP 为例：
+
+```powershell
+$ComponentVersion = "1.1.4"
+$PlatformKey = "windows_x86_64-msvc"
+$ComponentUpdateRepository = "$Build\ifw-component-update-com.simcae.dap-$ComponentVersion"
+$ComponentUpdateZip = "$Build\SimCAE-IFW-ComponentUpdate-com.simcae.dap-$ComponentVersion-$PlatformKey.zip"
+
+Remove-Item -LiteralPath $ComponentUpdateRepository -Recurse -Force -ErrorAction SilentlyContinue
+
+powershell -NoProfile -ExecutionPolicy Bypass -File ".\installer\scripts\build-ifw-repository.ps1" `
+  -PackageDir "$Build\package" `
+  -OutputDir $ComponentUpdateRepository `
+  -ZipFile $ComponentUpdateZip `
+  -Include "com.simcae.dap"
+```
+
+这条命令不会修改 `com.simcae.dap` 的 `<Version>`。它只是根据 `-Include` 选择已有组件，把该组件当前 `package.xml` 中写好的版本、显示名和依赖交给 `repogen.exe`，再生成本次组件更新 repository ZIP。
+
+如果一次更新多个组件：
+
+```powershell
+powershell -NoProfile -ExecutionPolicy Bypass -File ".\installer\scripts\build-ifw-repository.ps1" `
+  -PackageDir "$Build\package" `
+  -OutputDir "$Build\ifw-component-update-multi-$ComponentVersion" `
+  -ZipFile "$Build\SimCAE-IFW-ComponentUpdate-multi-$ComponentVersion-$PlatformKey.zip" `
+  -Include "com.simcae.app","com.simcae.dap"
+```
+
+生成后检查 ZIP 对应的展开目录：
+
+```powershell
+Test-Path "$ComponentUpdateRepository\Updates.xml"
+Get-ChildItem -LiteralPath $ComponentUpdateRepository
+Select-String -LiteralPath "$ComponentUpdateRepository\Updates.xml" -Pattern "com.simcae.dap|<Version>|<Dependencies>"
+```
+
+单 DAP 更新包的典型结构应类似：
+
+- `Updates.xml`
+- `com.simcae.dap/1.1.4meta.7z`
+- `com.simcae.dap/1.1.4view.7z`
+- `com.simcae.dap/1.1.4view.7z.sha1`
+
+如果 ZIP 解开后外面多套了一层目录，也可以上传；服务端会识别常见外层目录。但推荐让 ZIP 根部直接就是 `Updates.xml` 和组件目录，最不容易出错。
+
+### 11.5 上传组件更新
+
+管理后台操作：
+
+1. 打开“产品版本”，创建本次发布批次版本，例如 `1.1.4`。
+2. 打开“软件发布”，创建本次发布，通道仍选择 `stable`。
+3. 打开“发布包”，先点击要更新的软件卡片，进入该软件的发布包视图。
+4. 点击“新建组件更新包”。进入某个软件后，包类型固定为“组件更新”，产品固定为当前软件。
+5. 发布选择刚创建的 `1.1.4` 发布。
+6. 平台选择和 current repository 完全一致的 `windows / x86_64 / msvc`。
+7. 文件名填写 `SimCAE-IFW-ComponentUpdate-com.simcae.dap-1.1.4-windows_x86_64-msvc.zip`。
+8. 保存后点击“上传”。
+9. 选择上一步生成的 `$ComponentUpdateZip`。
+10. 上传成功后，发布包状态应变为“可用”。
+
+上传成功后，服务端会把更新组件合并进 current repository，未变化组件保持不变。
+
+### 11.6 上传后确认合并结果
+
+重新读取服务器仓库：
+
+```powershell
+$Base = "http://192.168.1.158:18000/api/v1/client/ifw/repositories/simcae/stable/windows_x86_64-msvc"
+(Invoke-WebRequest "$Base/Updates.xml" -UseBasicParsing).Content
+```
+
+预期：
+
+1. 更新过的组件版本变成新版本，例如 `com.simcae.dap` 是 `1.1.4`。
+2. 未更新的组件仍然存在，例如 `com.simcae.app` 还在。
+3. 新增组件能出现在 `Updates.xml` 中。
+4. 旧版本仓库仍保存在服务端 `releases/<版本>` 目录中，current 指向最新合并结果。
+
+### 11.7 常见失败提示
+
+| 提示含义 | 原因 | 处理 |
+| --- | --- | --- |
+| 当前产品、通道和平台下还没有可合并的 IFW 当前仓库 | 还没上传过完整交付包 | 先上传完整 Qt IFW 交付包 |
+| 组件版本不能倒退或重复 | 上传组件版本小于或等于服务器 current 版本 | 升高组件 `package.xml` 里的版本后重新生成 |
+| 组件依赖不存在 | 新组件依赖的组件不在 current 仓库，也不在本次包里 | 先发布依赖组件，或把依赖组件一起打进本次更新包 |
+| 缺少组件目录 | `Updates.xml` 声明了组件，但 ZIP 里没有对应目录 | 重新用 `build-ifw-repository.ps1` 生成 |
+| 包含未在 `Updates.xml` 声明的组件目录 | ZIP 里多了未声明目录 | 删除多余目录后重新压包 |
+| 未包含 `Updates.xml` | 上传的不是 repository ZIP，或服务端没有配置 `SIMCAE_IFW_REPOGEN_PATH` 来从 packages 自动生成 | 上传 repository 形态 ZIP |
+
+更新包失败时，服务端不会破坏原 current repository。
+
+## 十二、换源
+
+服务器地址变化时有两种处理方式：
+
+| 方式 | 适用场景 |
+| --- | --- |
+| 临时换源命令 | 单台客户机器临时切到新仓库 |
+| RepositoryUpdate 批量换源 | 已安装客户软件批量迁移仓库地址 |
+
+换源只影响 `maintenancetool.exe` 访问 IFW repository。Launcher / Updater 的 API 地址来自服务端注入的 `app_config.json`，需要通过新发布包或重新安装包更新。
+
+### 12.1 临时换源
+
+临时换源适合开发、测试、临时排查。它不会永久改安装包里的默认源。
+
+在 SIMCAE 项目根目录执行，假设客户软件安装在 `.tmp\maintenance-installed\SimCAE`：
+
+```powershell
+$Install = ".\.tmp\maintenance-installed\SimCAE"
+$Repo = "http://192.168.1.158:18000/api/v1/client/ifw/repositories/simcae/stable/windows_x86_64-msvc/"
+
+powershell -NoProfile -ExecutionPolicy Bypass -File ".\installer\scripts\switch-maintenance-repository.ps1" `
+  -MaintenanceToolPath "$Install\maintenancetool.exe" `
+  -RepositoryUrl $Repo `
+  -Mode Temp `
+  -Command check-updates `
+  -ClearCache
+```
+
+注意 `$Repo` 必须是仓库根地址，不能写到 `Updates.xml`：
+
+- 正确：`http://192.168.1.158:18000/api/v1/client/ifw/repositories/simcae/stable/windows_x86_64-msvc/`
+- 错误：`http://192.168.1.158:18000/api/v1/client/ifw/repositories/simcae/stable/windows_x86_64-msvc/Updates.xml`
+
+### 12.2 批量换源
+
+批量换源适合服务器域名或 IP 变更。做法是在下一次 repository 的 `Updates.xml` 里加入 `RepositoryUpdate`，让 MaintenanceTool 更新组件时顺便替换本机源地址。
+
+示例：把旧源 `http://192.168.1.158:18000/...` 替换为新源 `https://download.simcae.example.com/...`：
+
+```powershell
+$UpdatesXml = "$Build\ifw-repository\Updates.xml"
+$OldRepo = "http://192.168.1.158:18000/api/v1/client/ifw/repositories/simcae/stable/windows_x86_64-msvc/"
+$NewRepo = "https://download.simcae.example.com/api/v1/client/ifw/repositories/simcae/stable/windows_x86_64-msvc/"
+
+powershell -NoProfile -ExecutionPolicy Bypass -File ".\installer\scripts\write-repository-update.ps1" `
+  -UpdatesXml $UpdatesXml `
+  -Action replace `
+  -OldUrl $OldRepo `
+  -NewUrl $NewRepo `
+  -DisplayName "SimCAE stable component repository" `
+  -ClearExisting
+```
+
+写入后重新压 repository 或重新组装 Qt IFW 交付包，再上传到 SimCAE Hub。客户下一次通过 MaintenanceTool 检查或更新组件后，会把仓库地址换成新地址。
+
+## 十三、常见问题
+
+| 现象 | 原因和处理 |
+| --- | --- |
+| 上传提示缺少 `Updates.xml` | 选择的不是 repository 或交付包结构不对 |
+| MaintenanceTool 看不到更新 | 服务器仓库版本没有高于本机 `components.xml` 里的版本 |
+| 客户下载不到安装器 | 发布包不是 Qt IFW 交付包，或客户安装器生成/登记失败 |
+| Launcher 启动主程序失败 | `SIMCAE_LAUNCH_TOKEN` 和业务主程序编译时 token 不一致 |
+| 直接双击 `SimCAE.exe` 被拦截 | 这是启用 Launcher 启动门禁后的预期行为 |
+| 可选组件删除后 Updater 报缺文件 | Manifest 中可选组件文件没有标为可选，或组件边界划分不对 |

-客户端脚本说明
+SimCAE Hub 客户端脚本说明
-==============
+==========================
 
-本目录保存 update-client 的辅助脚本。项目根目录只保留源码、CMake 入口、Docs 和配置模板，脚本统一放在这里。
+本目录保存 Qt/C++ 客户端更新链路的辅助脚本。客户端仍然由
+Launcher、Updater、Bootstrap 和业务主程序组成，服务端接口使用当前
+SimCAE Hub 的 Go API。
 
 脚本列表：
 
 1. package-sdk.ps1
-   在 Windows 上生成给其他软件接入用的 UpdateClientSDK 包。
+   在 Windows 上生成给业务软件接入用的客户端更新运行时包。
-   注意：SDK 包只面向运行接入，不包含 config/server_config.json 和 config/server_config.qrc。
-   服务端地址必须在打包前写入源码目录 config/server_config.json，并重新编译进 Launcher/Updater。
 
 2. package-client.ps1
-   在 Windows 上生成某个具体产品的最终客户端发布包。
+   Windows 本地调试用的客户包脚本，需要手工提供 app_config.json。
+   新流程建议上传完整软件 ZIP 到 SimCAE Hub，由服务端生成最终配置。
 
 3. install-sdk.ps1
-   将 SDK 运行时复制到业务软件 Release 目录。
+   把客户端更新运行时复制到业务软件 Release 目录。
 
 4. package-sdk.sh
-   在 Linux 上生成给其他软件接入用的 UpdateClientSDK 包，输出 tar.gz。
+   在 Linux 上生成客户端更新运行时包，输出 tar.gz。
 
 5. package-client.sh
-   在 Linux 上生成某个具体产品的最终客户端发布包，输出 tar.gz。
+   Linux 本地调试用的客户包脚本，需要手工提供 app_config.json。
 
-推荐在 update-client 根目录执行：
+SDK 打包命令、两种打包模式、参数含义和输出位置，统一看：
 
-```powershell
+../updater打包成SDK.md
-.\scripts\package-sdk.ps1 `
-  -SourceDir .\out\bin\Release `
-  -OutputDir .\dist\UpdateClientSDK `
-  -ZipFile .\dist\UpdateClientSDK.zip `
-  -SdkVersion 0.1.0
-```
 
-```powershell
+生成 SDK 后，SDK 根目录里只带给 SIMCAE 发布人员看的 SIMCAE打包上传.md。
-.\scripts\package-client.ps1 `
+后续如何把 Launcher、Updater、Bootstrap 和必要运行库放进业务软件、如何
-  -SourceDir .\out\bin\Release `
+组装 Qt IFW 交付包并上传，以该文档为准。
-  -ConfigFile .\config\app_config.json `
-  -OutputDir .\dist\UpdateClient `
-  -ZipFile .\dist\UpdateClient.zip
-```
-
-Linux 示例：
-
-```bash
-bash ./scripts/package-sdk.sh \
-  --source-dir ./out/linux/bin \
-  --output-dir ./dist/UpdateClientSDK-linux \
-  --archive ./dist/UpdateClientSDK-linux.tar.gz \
-  --sdk-version 0.1.0
-```
-
-```bash
-bash ./scripts/package-client.sh \
-  --source-dir /path/to/SimCAE \
-  --config-file /path/to/SimCAE/bin/config/app_config.json \
-  --output-dir ./dist/UpdateClient-linux \
-  --archive ./dist/UpdateClient-linux.tar.gz

+# Updater 打包成 SDK
+
+本文只说明如何从 `SIMCAE/update-client` 生成给 SIMCAE 打包流程使用的更新客户端 SDK。SIMCAE 如何拿这个 SDK 打客户安装器和交付包，见当前目录《SIMCAE打包上传.md》。
+
+## 一、SDK 包含什么
+
+SDK 用来把 Hub 更新客户端接入 SIMCAE 安装包。
+
+| 内容 | 作用 |
+| --- | --- |
+| `Launcher.exe` | 客户日常启动入口，检查整包更新并启动主程序 |
+| `Updater.exe` | 拉取 Manifest、下载发布包、校验 SHA-256、准备安装 |
+| `Bootstrap.exe` | 替换运行中文件时接管安装 |
+| Qt 运行库 | 可选，给没有单独 Qt 运行环境的接入方使用 |
+| `SIMCAE打包上传.md` | 给 SIMCAE 发布人员看的打包、交付包组装和上传说明 |
+
+SDK 不包含最终客户配置文件，例如 `app_config.json`、`server_config.json`、`server_config.qrc`、`manifest_public_key.pem`。这些文件由服务端在上传客户软件包或 Qt IFW 交付包时生成或注入。
+
+打包后的 SDK 根目录只放 `SIMCAE打包上传.md` 这一份使用说明。本文是维护者打 SDK 的说明，不随 SDK 一起交给接入方。
+
+## 二、编译 Release
+
+先进入 SIMCAE 仓库下的 `update-client` 目录。如果当前已经在 SIMCAE 仓库根目录：
+
+```powershell
+cd .\update-client
+```
+
+然后执行：
+
+```powershell
+cmake --preset x64-release -DSIMCAE_OPENSSL_ROOT="C:\Program Files\OpenSSL-Win64"
+cmake --build --preset x64-release
+```
+
+如果 OpenSSL 安装在其他目录，只改 `SIMCAE_OPENSSL_ROOT` 这一项。
+
+编译完成后，Release 产物通常位于 `out/bin/Release`。
+
+检查核心程序：
+
+```powershell
+Test-Path .\out\bin\Release\Launcher.exe
+Test-Path .\out\bin\Release\Updater.exe
+Test-Path .\out\bin\Release\Bootstrap.exe
+```
+
+预期都返回 `True`。
+
+## 三、打包不带 Qt 运行库的 SDK
+
+适用于接入方已经有 Qt 运行环境，或希望自己控制 Qt DLL 的情况。
+
+```powershell
+.\scripts\package-sdk.ps1 `
+  -SourceDir .\out\bin\Release `
+  -OutputDir .\dist\UpdateClientSDK `
+  -ZipFile .\dist\UpdateClientSDK.zip `
+  -SdkVersion 0.1.0
+```
+
+输出：
+
+| 输出 | 说明 |
+| --- | --- |
+| `dist\UpdateClientSDK` | 不带 Qt 运行库的 SDK 展开目录 |
+| `dist\UpdateClientSDK.zip` | 不带 Qt 运行库的 SDK 压缩包 |
+
+## 四、打包带 Qt 运行库的 SDK
+
+适用于接入方不想单独准备 Qt DLL，或者希望拿到后能直接放进安装包。
+
+```powershell
+.\scripts\package-sdk.ps1 `
+  -SourceDir .\out\bin\Release `
+  -OutputDir .\dist\UpdateClientSDK-With-QtDll `
+  -ZipFile .\dist\UpdateClientSDK-With-QtDll.zip `
+  -SdkVersion 0.1.0 `
+  -IncludeQtRuntime
+```
+
+这里的 `With-QtDll` 表示包里带的是运行所需的 Qt DLL，不是完整 Qt SDK。
+
+输出：
+
+| 输出 | 说明 |
+| --- | --- |
+| `dist\UpdateClientSDK-With-QtDll` | 带 Qt 运行库 DLL 的 SDK 展开目录 |
+| `dist\UpdateClientSDK-With-QtDll.zip` | 推荐交给 SIMCAE 开发者的 SDK 压缩包 |
+
+## 五、打包后检查
+
+```powershell
+Test-Path .\dist\UpdateClientSDK-With-QtDll\bin\Launcher.exe
+Test-Path .\dist\UpdateClientSDK-With-QtDll\bin\Updater.exe
+Test-Path .\dist\UpdateClientSDK-With-QtDll\bin\Bootstrap.exe
+Test-Path .\dist\UpdateClientSDK-With-QtDll\SIMCAE打包上传.md
+Test-Path .\dist\UpdateClientSDK-With-QtDll.zip
+```
+
+预期都返回 `True`。
+
+## 六、不要提交的内容
+
+当前仓库的 `.gitignore` 已忽略这些本地内容：
+
+- `thirdparty/`
+- `out/`
+- `dist/`
+- `*.exe`
+- `*.dll`
+- `*.zip`
+- `config/app_config.json`
+- `config/client_identity.dat`
+- `config/local_state.json`
+- `config/version_policy.dat`
+
+提交前看一下：
+
+```powershell
+git status --short
+```
+
+不要把本地依赖、编译产物、SDK ZIP、客户配置和运行状态提交进仓库。
