+
+## 技术栈
+
+- C++17
+- Qt 6 Widgets
+- Qt 6 Network
+- Qt 6 Multimedia
+- CMake
+- PNG 图片序列帧
+- JSON 配置文件
+- Windows 10 / Windows 11 优先
+
+## 构建
+
+推荐环境：
+
+- Qt 6.5.3
+- CMake 3.20+
+- Ninja
+- MinGW 11.2.0 或已配置好的 Qt MSVC Kit
+
+MinGW 示例：
+
+```powershell
+cmake -S . -B build/mingw-debug -G Ninja `
+  -DCMAKE_BUILD_TYPE=Debug `
+  -DCMAKE_PREFIX_PATH=D:/Qt/6.5.3/mingw_64 `
+  -DCMAKE_C_COMPILER=D:/Qt/Tools/mingw1120_64/bin/gcc.exe `
+  -DCMAKE_CXX_COMPILER=D:/Qt/Tools/mingw1120_64/bin/g++.exe
+
+cmake --build build/mingw-debug
+```
+
+如果使用 Qt Creator，也可以直接打开根目录 `CMakeLists.txt`，选择合适的 Qt Kit 后构建。
+
+## 应用图标
+
+当前应用图标位于：
+
+```text
+resources/icons/app_icon.ico
+resources/icons/app_icon_1024.png
+```
+
+`app_icon.ico` 用于窗口图标、托盘图标和 Windows exe 资源图标；托盘图标加载失败时会回退到默认角色包的 `preview.png`。`app_icon_1024.png` 作为高分辨率源图保留。
+运行时会优先读取可执行文件同级的 `resources/icons/`，找不到时回退到源码目录下的 `resources/icons/`。Windows exe 图标需要重新构建后生效。
+
+## 角色包
+
+当前默认角色包位于：
+
+```text
+resources/characters/shiroko/
+```
+
+内置角色包按 `resources/characters/<characterId>/` 组织。用户导入的角色包不会写入安装目录，而是复制到用户数据目录：
+
+```text
+QStandardPaths::AppDataLocation/characters/<characterId>/
+```
+
+角色包基本结构：
+
+```text
+resources/characters/shiroko/
+  character.json
+  preview.png
+  idle/
+  talk/
+  think/
+  sleep/
+  happy/
+  drag/
+  error/
+```
+
+当前素材版本为 `2.1.0-stable`，所有帧使用 512x512 透明画布。当前实现会读取当前角色包的各状态配置，并按 `character.json` 中的 FPS 播放。
+运行时会合并内置角色和用户导入角色；内置资源优先读取可执行文件同级的 `resources/characters/`，找不到时回退到源码目录下的 `resources/characters/`。
+
+角色导入：
+
+- 只支持导入本地文件夹，不支持 zip
+- 导入前先验证源文件夹；验证失败只弹窗提示，不复制、不创建、不覆盖文件
+- 验证通过后复制到用户数据目录
+- 角色 id 优先读取 `character.json` 的 `id`；为空时使用文件夹名
+- 角色 id 只允许 ASCII 字母、数字、点、下划线和短横线，且不能以点开头或结尾
+- 用户角色同名时会询问是否覆盖
+- 内置角色 id 不能被导入包覆盖
+- 验证要求：`character.json` 可解析、id 安全、存在 `idle` 和 `defaultState`、状态路径安全、fps 合法、每个声明状态至少有一张可读 PNG
+- 如果 `base.anchorY + bubble.offsetY` 计算出的气泡锚点明显偏低，导入时会提示用户检查配置，但不强制阻止导入
+- 只允许删除用户导入角色；选择内置角色删除时只会提示“不能删除内置角色”，不做文件操作
+- 设置页支持导出当前选择的角色到用户选择目录，内置角色和用户角色都可以导出副本
+- 导出目标目录已存在时会二次确认；不确认时不会覆盖
+- 设置页支持打开用户角色目录，便于检查导入角色文件
+
+懒加载现状：
+
+- `enableLazyLoad=true` 时，启动阶段只建立状态到帧路径的索引
+- 某个状态首次播放时加载该状态的 PNG 帧
+- 启动后会在主线程按批次预热常用状态，避免一次性加载全部帧
+- 已加载状态按状态级 LRU 策略管理，超过动画缓存上限时卸载非保护状态
+- 单轮预热不会反复重新加载刚被 LRU 卸载的状态，避免缓存上限较低时出现加载/卸载循环
+- 隐藏到托盘时可释放非保护动画缓存
+- `enableLazyLoad=false` 时仍保持启动阶段加载全部状态帧的兼容行为
+
+## 天气查询
+
+当前支持通过聊天输入查询基础天气，例如：
+
+```text
+西安天气怎么样
+明天西安天气怎么样
+后天纽约天气
+未来三天北京天气
+今天天气怎么样
+```
+
+天气查询使用 Open-Meteo Forecast API 和 Open-Meteo Geocoding API，不需要 API Key。回复采用稳定模板，不依赖 AI 润色。支持当前/今天、明天、后天和未来 1-3 天基础天气；空气质量、天气预警、天气提醒联动、复杂小时级降雨判断和穿衣指数暂不支持。
+
+当前 v1 推荐使用市级城市名。用户仍可输入天气源可识别的中文或英文地名，但区县、乡镇、街道不保证精确识别，可能无法匹配，或被匹配到上级/同名城市。当前会读取天气源返回的前 5 个地理编码候选；如果存在同名城市，仍使用第一个结果查询天气，并在回复中提示当前使用的城市和其他候选。
+
+城市来源优先级：
+- 用户输入明确城市
+- 设置页“天气”中的默认城市
+- 默认城市为空且开启开关时，根据公网 IP 定位判断城市
+
+当使用设置页默认城市或公网 IP 定位时，回复会明确说明城市来源。公网 IP 定位使用 ipapi.co；如不希望请求该服务，可在设置页关闭“无默认城市时根据公网 IP 判断城市”。
+
+设置页“天气”中提供“测试默认城市”按钮，只验证输入框当前城市会匹配到哪个城市、行政区和国家，不自动保存配置；最终保存仍由设置页 Save 控制。
+
+天气配置保存到：
+
+```text
+QStandardPaths::AppConfigLocation/weather_config.json
+```
+
+天气配置损坏时会备份为：
+
+```text
+weather_config.broken.yyyyMMdd-HHmmss.json
+```
+
+天气查询由独立 `src/weather/` 模块处理，`PetWindow` 只负责展示查询状态和结果。AI 正在请求或流式回复时不会启动天气查询，以避免覆盖 AI 气泡。
+
+## 聊天历史管理
+
+聊天记录默认只保存在内存中。设置页“聊天”中开启“保存聊天记录到本地”后，会保存到：
+
+```text
+QStandardPaths::AppConfigLocation/conversation_history.json
+```
+
+历史管理能力：
+
+- 支持按关键词搜索当前聊天历史
+- 支持按 Provider 和模型筛选；旧历史缺少元数据时会按未知处理
+- 支持导出当前筛选结果为 Markdown
+- 支持导出当前筛选结果为 JSON
+- 清空聊天记录需要确认，并会清空当前内存和本地保存记录
+- 导出内容不包含 API Key 或 AI 配置
+- 日志不会记录完整聊天正文
+
+## 定时提醒和音效
+
+当前支持通过聊天输入创建一次性和重复本地提醒，例如：
+
+```text
+10分钟后提醒我喝水
+半小时后提醒我休息
+一个半小时后提醒我喝水
+明天9点提醒我开会
+后天9点提醒我开会
+6月3日9点提醒我提交
+下周一上午10点提醒我周会
+每天9点提醒我打卡
+每天提醒我9点打卡
+每日晚上8点提醒我吃药
+每周一上午10点提醒我周会
+每周一提醒我上午10点周会
+每星期五下午3点提醒我提交周报
+每月3号9点提醒我交报告
+每月3号提醒我9点交报告
+提醒列表
+取消喝水提醒
+```
+
+提醒数据保存到：
+
+```text
+QStandardPaths::AppConfigLocation/reminders.json
+```
+
+提醒数据使用原子写入，写入失败时不会触发到点 UI，也不会覆盖旧的有效提醒文件。已触发和已取消记录会写入 `finishedAt`；旧版数据没有该字段时按 `remindAt` 兼容读取。
+
+提醒调度保留最近提醒的精确 timer，同时每 60 秒做一次兜底扫描；程序显示、外部激活或系统睡眠唤醒后，都会重新检查已到期 pending 提醒。
+
+设置页支持编辑 pending 提醒的标题、下一次时间和重复规则；已触发/已取消历史只读。历史记录默认只保留最近 20 天，设置页“清理20天前历史”只删除超过 20 天的已触发/已取消记录，不影响 pending。
+
+提醒文件损坏时会备份为：
+
+```text
+reminders.broken.yyyyMMdd-HHmmss.json
+```
+
+内置提醒音效位于：
+
+```text
+resources/sounds/reminders/
+```
+
+用户导入的提醒音效保存到：
+
+```text
+QStandardPaths::AppDataLocation/sounds/reminders/
+```
+
+音效规则：
+
+- 默认音效为 `reminder_default`
+- 提醒触发时使用当前设置页选择的全局音效；修改音效后对所有未触发提醒立即生效
+- 内置音效可切换、可试听，但不能在设置页删除
+- 用户音效只支持导入 PCM wav
+- 用户导入音效可切换、可试听、可删除
+- 删除当前用户音效后会回退到 `reminder_default`
+
+触发规则：
+
+- 桌宠可见时显示气泡，不发系统通知
+- 桌宠隐藏时发 Windows 托盘通知，不在下次显示时补气泡
+- AI 正在请求或流式回复时，按隐藏场景处理：播放音效并发 Windows 托盘通知，不显示气泡
+- 托盘或系统通知后端不可用时只记录日志，不补气泡
+- 用户拖动中不打断 `drag`，拖动结束后显示气泡
+- 多条提醒同时触发时，可见状态下会按队列逐条展示
+- 桌宠可见触发时显示 `知道了` 和 `5分钟后再提醒`
+- `5分钟后再提醒` 会创建一条新的一次性提醒，不影响原重复规则
+- 重复提醒支持 `每天 / 每周 / 每月`；`工作日 / 每两天 / 每月最后一天 / 自定义间隔 / 农历` 等复杂规则暂不支持
+- 每月 31 号这类规则会跳过不存在该日期的月份，寻找下一个有效月份
+- 用户音效删除仅允许删除用户音效目录内的安全 sound id，内置音效和非法路径不会被删除
+
+## 本地文件操作
+
+本地文件操作通过聊天意图触发，但不会直接使用聊天文本里的路径。所有文件和文件夹都必须由用户在系统文件选择框中主动选择。
+
+当前 v1 支持：
+
+- 读取用户选择的常见文本文件：txt、md、log、json、csv、ini、xml、yaml
+- 列出用户选择的文件夹，最多显示前 200 项
+- 复制用户选择的文件到用户选择的目标文件夹
+- 为用户选择的文件创建同目录备份
+- 重命名用户选择的文件
+
+安全规则：
+
+- 写操作会先展示操作计划并要求确认
+- 不覆盖已有文件
+- 不删除文件
+- 不移动大量文件
+- 不执行脚本或命令
+- 不访问 Windows 系统目录
+- 拒绝符号链接或符号链接目录内的路径
+
+暂不支持：
+
+- zip 打包
+- 删除、覆盖、移动
+- 修改源码
+- 执行脚本或命令
+
+## 联网模式
+
+联网模式不是搜索引擎聚合器。用户在输入框打开“联网”开关后，普通聊天会进入当前 AI Provider 的原生联网能力：
+
+- OpenAI 官方 Provider：使用 Responses API Web Search。
+- Google Gemini Provider：使用 Gemini Google Search grounding。
+- DeepSeek 官方 API：当前不提供托管联网搜索工具，显示“不支持原生联网”。
+- Custom / 第三方 OpenAI-Compatible：默认无法确认联网能力，不会尝试旧搜索页抓取。
+
+配置保存到：
+
+```text
+QStandardPaths::AppConfigLocation/web_config.json
+```
+
+交互规则：
+
+- 联网开关默认关闭，避免隐私和费用意外。
+- 设置页“联网模式”只显示能力状态、开关记忆、默认开关、超时、来源展示和测试联网模式。
+- 当前模型不支持联网时，输入框打开联网后会明确提示，不发起伪联网请求。
+- 支持联网的 Provider 返回来源时会展示来源；模型判断无需联网时允许无来源，并显示“模型未使用联网来源”。
+- 旧 `search_config.json` 已废弃，新版不会读取、迁移或写入。
+
+后续可扩展：
+
+- 更多 AI Provider 的原生联网适配。
+- 结构化搜索 API 或自建联网后端。
+- 更细粒度的来源证据摘录和引用 UI。
+
+## 应用启动
+
+应用启动是独立能力，不归入本地文件操作。可通过聊天输入：
+
+```text
+打开 Codex
+启动酷狗音乐
+帮我打开 VSCode
+```
+
+配置保存到：
+
+```text
+QStandardPaths::AppConfigLocation/launcher_config.json
+```
+
+设置页“应用启动”支持：
+
+- 启用或关闭应用启动
+- 未知应用允许用户手动选择 `.exe`
+- 登记应用名称和别名
+- 编辑、删除、测试启动已登记应用
+
+安全边界：
+
+- 启动前始终二次确认，确认内容包含应用名、路径、工作目录和来源
+- 只允许启动 `.exe` 或开始菜单 `.lnk` 快捷方式
+- 不执行 `.bat` / `.cmd` / `.ps1` / `.vbs` / `.js` / `.msi`
+- 不执行聊天文本里的命令
+- 不拼接聊天文本参数
+- 不以管理员权限启动
+- 手选 `.exe` 后可选择记住为当前名称，后续走登记应用匹配
+
+## 配置和日志
+
+应用配置保存到 Qt 标准配置目录：
+
+```text
+QStandardPaths::AppConfigLocation/app_config.json
+```
+
+配置损坏时会备份为带时间戳的文件：
+
+```text
+app_config.broken.yyyyMMdd-HHmmss.json
+ai_config.broken.yyyyMMdd-HHmmss.json
+conversation_history.broken.yyyyMMdd-HHmmss.json
+weather_config.broken.yyyyMMdd-HHmmss.json
+web_config.broken.yyyyMMdd-HHmmss.json
+launcher_config.broken.yyyyMMdd-HHmmss.json
+```
+
+日志输出到文件，不输出到控制台：
+
+```text
+QStandardPaths::AppConfigLocation/logs/QtDesktopPet.log
+```
+
+如果 Qt 无法取得标准配置目录，则回退到当前工作目录下的 `logs/QtDesktopPet.log`。
+
+日志轮转规则：
+
+- 单个日志文件超过 2MB 时轮转
+- 最多保留 3 个旧日志文件
+- 文件名为 `QtDesktopPet.log.1`、`QtDesktopPet.log.2`、`QtDesktopPet.log.3`
+
+## 发布打包
+
+仓库提供 Windows Release 打包脚本。脚本不负责 CMake 构建，先手动完成 Release 构建，再把 exe 路径传给脚本：
+
+```powershell
+powershell -NoProfile -ExecutionPolicy Bypass -File tools/package_release.ps1 -ExePath build/release/QtDesktopPet.exe
+```
+
+脚本会生成目录包和 zip：
+
+```text
+dist/QtDesktopPet-<version>-windows-x64/
+dist/QtDesktopPet-<version>-windows-x64.zip
+```
+
+发布目录包含：
+
+```text
+QtDesktopPet.exe
+Qt runtime
+resources/characters/
+resources/icons/
+resources/sounds/
+LICENSE
+README.md
+```
+
+脚本会调用 `windeployqt.exe` 收集 Qt 运行库。若当前 PATH 找不到 `windeployqt.exe`，需要指定 Qt bin 目录下的工具路径：
+
+```powershell
+powershell -NoProfile -ExecutionPolicy Bypass -File tools/package_release.ps1 `
+  -ExePath build/release/QtDesktopPet.exe `
+  -WindeployQtPath D:\Qt\6.x.x\msvcXXXX_64\bin\windeployqt.exe
+```
+
+生成 Inno Setup 安装器：
+
+```powershell
+powershell -NoProfile -ExecutionPolicy Bypass -File tools/package_release.ps1 `
+  -ExePath build/release/QtDesktopPet.exe `
+  -BuildInstaller
+```
+
+安装器最终默认输出到项目根目录：
+
+```text
+QtDesktopPet-<version>-windows-x64-setup.exe
+```
+
+脚本会先让 Inno Setup 输出到当前盘符下的纯 ASCII 临时目录，例如 `D:\QtDesktopPetInstallerOutput`，再把最终安装包复制回项目根目录，避免中文项目路径下出现 `EndUpdateResource failed (5)`。如果需要改变最终安装包目录，可传入 `-InstallerOutputDir`：
+
+```powershell
+powershell -NoProfile -ExecutionPolicy Bypass -File tools/package_release.ps1 `
+  -ExePath build/release/QtDesktopPet.exe `
+  -BuildInstaller `
+  -InstallerOutputDir D:\ReleaseOutput
+```
+
+如果需要改变 Inno Setup 的临时编译输出目录，可传入 `-InstallerWorkOutputDir`。
+
+本地生成的安装包也可以集中放到 `release_packages/`：
+
+```powershell
+powershell -NoProfile -ExecutionPolicy Bypass -File tools/package_release.ps1 `
+  -ExePath build/release/QtDesktopPet.exe `
+  -BuildInstaller `
+  -InstallerOutputDir release_packages
+```
+
+`dist/` 和 `release_packages/` 都是本地发布产物目录，不进入 Git。
+
+脚本默认优先查找：
+
+```text
+D:\Inno Setup 7\ISCC.exe
+D:\Inno Setup 6\ISCC.exe
+C:\Program Files (x86)\Inno Setup 7\ISCC.exe
+C:\Program Files (x86)\Inno Setup 6\ISCC.exe
+```
+
+如果 Inno Setup 安装在其他位置，可传入 `-InnoCompilerPath`。
+
+安装器页面提供可选项：
+
+- 创建桌面快捷方式，默认不勾选。
+- 开机自启动，默认不勾选；勾选后写入当前用户 `HKCU\Software\Microsoft\Windows\CurrentVersion\Run`，不需要管理员权限。
+
+应用内设置页的“应用设置”页也提供“开机自启动”开关，保存后会立即写入或移除同一个当前用户 Run 项。卸载时会清理该 Run 项，避免卸载后残留自启动入口。
+
+安装器卸载时会询问是否同时删除用户配置、导入角色、聊天记录和日志；用户确认后会在卸载完成阶段删除当前用户下的 QtDesktopPet 数据目录。
+
+## 开发诊断
+
+仓库提供开发用性能采样脚本，不进入普通用户发布包：
+
+```powershell
+powershell -NoProfile -ExecutionPolicy Bypass -File tools/perf_sample.ps1
+```
+
+默认采样当前 `QtDesktopPet` 进程 5 分钟，每 5 秒一条，CSV 输出到：
+
+```text
+reports/perf/
+```
+
+`reports/perf/` 已加入 `.gitignore`。稳定性检查记录模板见：
+
+```text
+docs/performance_stability_check.md
+```
+
+发布包应排除 `tools/`、`docs/`、`reports/`、`build/`、`dist/`、`release_packages/` 和 `.git/`，只保留运行必需文件、`resources/characters/`、`resources/icons/`、`resources/sounds/`、`LICENSE` 和必要说明。
+
+## AI 配置和聊天
+
+当前正式聊天支持 OpenAI Compatible 和 Google Gemini 两类协议。已提供以下 Provider 配置入口：
+
+- OpenAI
+- Google
+- DeepSeek
+- Custom
+
+其中 OpenAI、DeepSeek、Custom 走 OpenAI Compatible 形式配置；Google 走 Gemini 原生 REST 接口。旧版保存过的已废弃 Provider 配置会在读取 AI 配置时清理，废弃 Provider 被选中时会回退为 `custom`。
+
+已支持：
+
+- 用户自定义 Base URL
+- 用户自定义 API Key
+- 用户自定义 Model
+- 用户自定义 Path
+- 超时、Temperature、Max Tokens
+- 流式输出
+- Google Gemini `generateContent` / `streamGenerateContent`
+- 请求中切换 `think`
+- 收到首段输出后切换并保持 `talk`
+- 失败时切换 `error`
+- API Key 不写入日志，不在错误提示中完整显示
+- 对话历史面板记录用户消息和 AI 最终回复
+
+AI 测试入口已从角色右键菜单移除，并迁移到设置页。
+
+## 隐私说明
+
+程序只会把用户消息发送到用户自己配置的接口。用户需要自行判断第三方代理、中转服务或自建服务是否可信。项目不会默认承诺第三方接口的隐私安全。
+
+日志会记录请求诊断信息，例如 Provider、Base URL 主机、Path、HTTP 状态码、响应大小、错误摘要等；日志不应记录完整 API Key、Authorization Header、完整消息正文或完整错误响应正文。错误响应只保留脱敏摘要。
+
+当前对话历史默认保存在内存中，已支持内存历史上限、请求上下文截取和可选本地历史保存；相关上限可在设置页调整。
+
+## 素材版权说明
+
+源码采用 MIT License。
+
+角色素材、图片、图标等资源需要单独确认授权。当前 `shiroko` 素材用于桌宠加载器、动画和状态切换测试；在公开发布或正式分发前，需要确认素材的版权、再分发权限和适用范围。
+
+用户导入或替换的素材，其版权责任由用户自行承担。
+
+## 许可证
+
+项目源码使用 MIT License，见 [LICENSE](LICENSE)。

-- Qt 6.5.3
+## Build
+
+Recommended environment:
+
+- Qt 6.5+
 - CMake 3.20+
 - Ninja
-- MinGW 11.2.0 或已配置好的 Qt MSVC Kit
+- MinGW 11.2.0 or a configured Qt MSVC Kit
 
-MinGW 示例：
+Example with MinGW:
 
 ```powershell
-cmake -S . -B build/mingw-debug -G Ninja `
-  -DCMAKE_BUILD_TYPE=Debug `
+cmake -S . -B build/mingw-release -G Ninja `
+  -DCMAKE_BUILD_TYPE=Release `
   -DCMAKE_PREFIX_PATH=D:/Qt/6.5.3/mingw_64 `
   -DCMAKE_C_COMPILER=D:/Qt/Tools/mingw1120_64/bin/gcc.exe `
   -DCMAKE_CXX_COMPILER=D:/Qt/Tools/mingw1120_64/bin/g++.exe
 
-cmake --build build/mingw-debug
+cmake --build build/mingw-release
 ```
 
-如果使用 Qt Creator，也可以直接打开根目录 `CMakeLists.txt`，选择合适的 Qt Kit 后构建。
+Qt Creator users can open `CMakeLists.txt` directly and build with a matching Qt Kit.
 
-## 应用图标
+## Package
 
-当前应用图标位于：
-
-```text
-resources/icons/app_icon.ico
-resources/icons/app_icon_1024.png
-```
-
-`app_icon.ico` 用于窗口图标、托盘图标和 Windows exe 资源图标；托盘图标加载失败时会回退到默认角色包的 `preview.png`。`app_icon_1024.png` 作为高分辨率源图保留。
-运行时会优先读取可执行文件同级的 `resources/icons/`，找不到时回退到源码目录下的 `resources/icons/`。Windows exe 图标需要重新构建后生效。
-
-## 角色包
-
-当前默认角色包位于：
-
-```text
-resources/characters/shiroko/
-```
-
-内置角色包按 `resources/characters/<characterId>/` 组织。用户导入的角色包不会写入安装目录，而是复制到用户数据目录：
-
-```text
-QStandardPaths::AppDataLocation/characters/<characterId>/
-```
-
-角色包基本结构：
-
-```text
-resources/characters/shiroko/
-  character.json
-  preview.png
-  idle/
-  talk/
-  think/
-  sleep/
-  happy/
-  drag/
-  error/
-```
-
-当前素材版本为 `2.1.0-stable`，所有帧使用 512x512 透明画布。当前实现会读取当前角色包的各状态配置，并按 `character.json` 中的 FPS 播放。
-运行时会合并内置角色和用户导入角色；内置资源优先读取可执行文件同级的 `resources/characters/`，找不到时回退到源码目录下的 `resources/characters/`。
-
-角色导入：
-
-- 只支持导入本地文件夹，不支持 zip
-- 导入前先验证源文件夹；验证失败只弹窗提示，不复制、不创建、不覆盖文件
-- 验证通过后复制到用户数据目录
-- 角色 id 优先读取 `character.json` 的 `id`；为空时使用文件夹名
-- 角色 id 只允许 ASCII 字母、数字、点、下划线和短横线，且不能以点开头或结尾
-- 用户角色同名时会询问是否覆盖
-- 内置角色 id 不能被导入包覆盖
-- 验证要求：`character.json` 可解析、id 安全、存在 `idle` 和 `defaultState`、状态路径安全、fps 合法、每个声明状态至少有一张可读 PNG
-- 如果 `base.anchorY + bubble.offsetY` 计算出的气泡锚点明显偏低，导入时会提示用户检查配置，但不强制阻止导入
-- 只允许删除用户导入角色；选择内置角色删除时只会提示“不能删除内置角色”，不做文件操作
-
-懒加载现状：
-
-- `enableLazyLoad=true` 时，启动阶段只建立状态到帧路径的索引
-- 某个状态首次播放时加载该状态的 PNG 帧
-- 启动后会在主线程按批次预热常用状态，避免一次性加载全部帧
-- 已加载状态按状态级 LRU 策略管理，超过动画缓存上限时卸载非保护状态
-- 单轮预热不会反复重新加载刚被 LRU 卸载的状态，避免缓存上限较低时出现加载/卸载循环
-- 隐藏到托盘时可释放非保护动画缓存
-- `enableLazyLoad=false` 时仍保持启动阶段加载全部状态帧的兼容行为
-
-## 定时提醒和音效
-
-当前支持通过聊天输入创建一次性和重复本地提醒，例如：
-
-```text
-10分钟后提醒我喝水
-半小时后提醒我休息
-一个半小时后提醒我喝水
-明天9点提醒我开会
-后天9点提醒我开会
-6月3日9点提醒我提交
-下周一上午10点提醒我周会
-每天9点提醒我打卡
-每天提醒我9点打卡
-每日晚上8点提醒我吃药
-每周一上午10点提醒我周会
-每周一提醒我上午10点周会
-每星期五下午3点提醒我提交周报
-每月3号9点提醒我交报告
-每月3号提醒我9点交报告
-提醒列表
-取消喝水提醒
-```
-
-提醒数据保存到：
-
-```text
-QStandardPaths::AppConfigLocation/reminders.json
-```
-
-提醒数据使用原子写入，写入失败时不会触发到点 UI，也不会覆盖旧的有效提醒文件。已触发和已取消记录会写入 `finishedAt`；旧版数据没有该字段时按 `remindAt` 兼容读取。
-
-提醒调度保留最近提醒的精确 timer，同时每 60 秒做一次兜底扫描；程序显示、外部激活或系统睡眠唤醒后，都会重新检查已到期 pending 提醒。
-
-设置页支持编辑 pending 提醒的标题、下一次时间和重复规则；已触发/已取消历史只读。历史记录默认只保留最近 20 天，设置页“清理20天前历史”只删除超过 20 天的已触发/已取消记录，不影响 pending。
-
-提醒文件损坏时会备份为：
-
-```text
-reminders.broken.yyyyMMdd-HHmmss.json
-```
-
-内置提醒音效位于：
-
-```text
-resources/sounds/reminders/
-```
-
-用户导入的提醒音效保存到：
-
-```text
-QStandardPaths::AppDataLocation/sounds/reminders/
-```
-
-音效规则：
-
-- 默认音效为 `reminder_default`
-- 提醒触发时使用当前设置页选择的全局音效；修改音效后对所有未触发提醒立即生效
-- 内置音效可切换、可试听，但不能在设置页删除
-- 用户音效只支持导入 PCM wav
-- 用户导入音效可切换、可试听、可删除
-- 删除当前用户音效后会回退到 `reminder_default`
-
-触发规则：
-
-- 桌宠可见时显示气泡，不发系统通知
-- 桌宠隐藏时发 Windows 托盘通知，不在下次显示时补气泡
-- AI 正在请求或流式回复时，按隐藏场景处理：播放音效并发 Windows 托盘通知，不显示气泡
-- 托盘或系统通知后端不可用时只记录日志，不补气泡
-- 用户拖动中不打断 `drag`，拖动结束后显示气泡
-- 多条提醒同时触发时，可见状态下会按队列逐条展示
-- 桌宠可见触发时显示 `知道了` 和 `5分钟后再提醒`
-- `5分钟后再提醒` 会创建一条新的一次性提醒，不影响原重复规则
-- 重复提醒支持 `每天 / 每周 / 每月`；`工作日 / 每两天 / 每月最后一天 / 自定义间隔 / 农历` 等复杂规则暂不支持
-- 每月 31 号这类规则会跳过不存在该日期的月份，寻找下一个有效月份
-- 用户音效删除仅允许删除用户音效目录内的安全 sound id，内置音效和非法路径不会被删除
-
-## 配置和日志
-
-应用配置保存到 Qt 标准配置目录：
-
-```text
-QStandardPaths::AppConfigLocation/app_config.json
-```
-
-配置损坏时会备份为带时间戳的文件：
-
-```text
-app_config.broken.yyyyMMdd-HHmmss.json
-ai_config.broken.yyyyMMdd-HHmmss.json
-conversation_history.broken.yyyyMMdd-HHmmss.json
-```
-
-日志输出到文件，不输出到控制台：
-
-```text
-QStandardPaths::AppConfigLocation/logs/QtDesktopPet.log
-```
-
-如果 Qt 无法取得标准配置目录，则回退到当前工作目录下的 `logs/QtDesktopPet.log`。
-
-日志轮转规则：
-
-- 单个日志文件超过 2MB 时轮转
-- 最多保留 3 个旧日志文件
-- 文件名为 `QtDesktopPet.log.1`、`QtDesktopPet.log.2`、`QtDesktopPet.log.3`
-
-## 发布打包
-
-仓库提供 Windows Release 打包脚本。脚本不负责 CMake 构建，先手动完成 Release 构建，再把 exe 路径传给脚本：
-
-```powershell
-powershell -NoProfile -ExecutionPolicy Bypass -File tools/package_release.ps1 -ExePath build/release/QtDesktopPet.exe
-```
-
-脚本会生成目录包和 zip：
-
-```text
-dist/QtDesktopPet-<version>-windows-x64/
-dist/QtDesktopPet-<version>-windows-x64.zip
-```
-
-发布目录包含：
-
-```text
-QtDesktopPet.exe
-Qt runtime
-resources/characters/
-resources/icons/
-resources/sounds/
-LICENSE
-README.md
-```
-
-脚本会调用 `windeployqt.exe` 收集 Qt 运行库。若当前 PATH 找不到 `windeployqt.exe`，需要指定 Qt bin 目录下的工具路径：
+After building a Release executable, package it with:
 
 ```powershell
 powershell -NoProfile -ExecutionPolicy Bypass -File tools/package_release.ps1 `
-  -ExePath build/release/QtDesktopPet.exe `
-  -WindeployQtPath D:\Qt\6.x.x\msvcXXXX_64\bin\windeployqt.exe
+  -ExePath build/release/QtDesktopPet.exe
 ```
 
-生成 Inno Setup 安装器：
+To generate the Inno Setup installer:
 
 ```powershell
 powershell -NoProfile -ExecutionPolicy Bypass -File tools/package_release.ps1 `
@@ -299,113 +129,108 @@ powershell -NoProfile -ExecutionPolicy Bypass -File tools/package_release.ps1 `
   -BuildInstaller
 ```
 
-安装器最终默认输出到项目根目录：
+The installer supports optional desktop shortcut creation and optional Windows startup launch. Both are disabled by default.
+
+## Runtime Data
+
+Runtime configuration and user data are stored under Qt standard user directories:
+
+- `QStandardPaths::AppConfigLocation`
+- `QStandardPaths::AppDataLocation`
+
+Examples:
+
+- AI config: `ai_config.json`
+- App config: `app_config.json`
+- Conversation history: `conversation_history.json`
+- Reminders: `reminders.json`
+- Weather config: `weather_config.json`
+- Web mode config: `web_config.json`
+- Launcher config: `launcher_config.json`
+
+The app writes rotating logs under:
 
 ```text
-QtDesktopPet-<version>-windows-x64-setup.exe
+QStandardPaths::AppConfigLocation/logs/QtDesktopPet.log
 ```
 
-脚本会先让 Inno Setup 输出到当前盘符下的纯 ASCII 临时目录，例如 `D:\QtDesktopPetInstallerOutput`，再把最终安装包复制回项目根目录，避免中文项目路径下出现 `EndUpdateResource failed (5)`。如果需要改变最终安装包目录，可传入 `-InstallerOutputDir`：
+## AI And Privacy
+
+QtDesktopPet only sends chat content to the AI endpoint configured by the user.
+
+Important notes:
+
+- API keys are not logged.
+- Authorization headers are not logged.
+- Full user messages and full error bodies should not be logged.
+- On Windows, API keys are saved with DPAPI when available.
+- Third-party compatible APIs and proxy services are controlled by the user; this project cannot guarantee their privacy behavior.
+
+## Safety Boundaries
+
+The project intentionally keeps local automation conservative:
+
+- File operations require user-selected paths.
+- Write operations require confirmation.
+- File operations do not execute scripts or commands.
+- Application launch only supports `.exe` and Start Menu `.lnk` shortcuts.
+- Chat text is not converted into shell commands.
+- Startup integration writes only the current user's Windows `Run` entry.
+
+## Web Mode
+
+Web mode is an AI-native conversation feature, not a search engine scraper.
+
+Supported:
+
+- OpenAI official API with Responses API Web Search.
+- Google Gemini API with Google Search grounding.
+
+Not treated as supported native web access:
+
+- DeepSeek official API
+- Custom OpenAI-compatible endpoints
+- Third-party relay APIs
+
+Unsupported providers show an explicit message instead of falling back to unreliable search-page scraping.
+
+## Character Packages
+
+Built-in characters are placed under:
+
+```text
+resources/characters/<characterId>/
+```
+
+A character package contains:
+
+```text
+character.json
+preview.png
+idle/
+talk/
+think/
+sleep/
+happy/
+drag/
+error/
+```
+
+User-imported characters are copied to the user's app data directory instead of the installation directory.
+
+## Public Export
+
+This development workspace may contain internal planning and test documents. To create a clean public GitHub export, use:
 
 ```powershell
-powershell -NoProfile -ExecutionPolicy Bypass -File tools/package_release.ps1 `
-  -ExePath build/release/QtDesktopPet.exe `
-  -BuildInstaller `
-  -InstallerOutputDir D:\ReleaseOutput
+powershell -NoProfile -ExecutionPolicy Bypass -File tools/prepare_github_export.ps1 `
+  -OutputDir D:\DesktopPet-github-export
 ```
 
-如果需要改变 Inno Setup 的临时编译输出目录，可传入 `-InstallerWorkOutputDir`。
+The export excludes internal docs, reports, build outputs, release packages, local config, logs and Git metadata.
 
-本地生成的安装包也可以集中放到 `release_packages/`：
+## License
 
-```powershell
-powershell -NoProfile -ExecutionPolicy Bypass -File tools/package_release.ps1 `
-  -ExePath build/release/QtDesktopPet.exe `
-  -BuildInstaller `
-  -InstallerOutputDir release_packages
-```
+Source code is released under the MIT License. See [LICENSE](LICENSE).
 
-`dist/` 和 `release_packages/` 都是本地发布产物目录，不进入 Git。
-
-脚本默认优先查找：
-
-```text
-D:\Inno Setup 7\ISCC.exe
-D:\Inno Setup 6\ISCC.exe
-C:\Program Files (x86)\Inno Setup 7\ISCC.exe
-C:\Program Files (x86)\Inno Setup 6\ISCC.exe
-```
-
-如果 Inno Setup 安装在其他位置，可传入 `-InnoCompilerPath`。
-
-安装器卸载时会询问是否同时删除用户配置、导入角色、聊天记录和日志；用户确认后会在卸载完成阶段删除当前用户下的 QtDesktopPet 数据目录。
-
-## 开发诊断
-
-仓库提供开发用性能采样脚本，不进入普通用户发布包：
-
-```powershell
-powershell -NoProfile -ExecutionPolicy Bypass -File tools/perf_sample.ps1
-```
-
-默认采样当前 `QtDesktopPet` 进程 5 分钟，每 5 秒一条，CSV 输出到：
-
-```text
-reports/perf/
-```
-
-`reports/perf/` 已加入 `.gitignore`。稳定性检查记录模板见：
-
-```text
-docs/performance_stability_check.md
-```
-
-发布包应排除 `tools/`、`docs/`、`reports/`、`build/`、`dist/`、`release_packages/` 和 `.git/`，只保留运行必需文件、`resources/characters/`、`resources/icons/`、`resources/sounds/`、`LICENSE` 和必要说明。
-
-## AI 配置和聊天
-
-当前正式聊天支持 OpenAI Compatible 和 Google Gemini 两类协议。已提供以下 Provider 配置入口：
-
-- OpenAI
-- Google
-- DeepSeek
-- Custom
-
-其中 OpenAI、DeepSeek、Custom 走 OpenAI Compatible 形式配置；Google 走 Gemini 原生 REST 接口。旧版保存过的已废弃 Provider 配置会在读取 AI 配置时清理，废弃 Provider 被选中时会回退为 `custom`。
-
-已支持：
-
-- 用户自定义 Base URL
-- 用户自定义 API Key
-- 用户自定义 Model
-- 用户自定义 Path
-- 超时、Temperature、Max Tokens
-- 流式输出
-- Google Gemini `generateContent` / `streamGenerateContent`
-- 请求中切换 `think`
-- 收到首段输出后切换并保持 `talk`
-- 失败时切换 `error`
-- API Key 不写入日志，不在错误提示中完整显示
-- 对话历史面板记录用户消息和 AI 最终回复
-
-AI 测试入口已从角色右键菜单移除，并迁移到设置页。
-
-## 隐私说明
-
-程序只会把用户消息发送到用户自己配置的接口。用户需要自行判断第三方代理、中转服务或自建服务是否可信。项目不会默认承诺第三方接口的隐私安全。
-
-日志会记录请求诊断信息，例如 Provider、Base URL 主机、Path、HTTP 状态码、响应大小、错误摘要等；日志不应记录完整 API Key、Authorization Header、完整消息正文或完整错误响应正文。错误响应只保留脱敏摘要。
-
-当前对话历史默认保存在内存中，已支持内存历史上限、请求上下文截取和可选本地历史保存；相关上限可在设置页调整。
-
-## 素材版权说明
-
-源码采用 MIT License。
-
-角色素材、图片、图标等资源需要单独确认授权。当前 `shiroko` 素材用于桌宠加载器、动画和状态切换测试；在公开发布或正式分发前，需要确认素材的版权、再分发权限和适用范围。
-
-用户导入或替换的素材，其版权责任由用户自行承担。
-
-## 许可证
-
-项目源码使用 MIT License，见 [LICENSE](LICENSE)。
+Character art, icons, sounds and other media assets may have separate copyright requirements. Confirm asset licensing before public redistribution.

+- 支持 OpenAI 官方 Provider 的 Responses API Web Search。
+- 支持 Google Gemini Provider 的 Google Search grounding。
+- DeepSeek 官方 API 当前不提供托管联网搜索工具，显示“不支持原生联网”。
+- Custom / 第三方 OpenAI-Compatible 默认无法确认联网能力，不发送未知联网参数，不做旧搜索页抓取。
+- 设置页改为“联网模式”：显示当前能力状态、开关记忆、默认开关、Provider 模式、超时、来源展示和测试联网模式。
+- 旧 `search_config.json` 已废弃；新版使用 `web_config.json`，损坏时备份为 `web_config.broken.yyyyMMdd-HHmmss.json`。
+
+边界：
+
+- 不再默认每次联网，模型可判断稳定常识无需联网。
+- 不做搜索结果页 HTML 解析，避免登录、帮助、反馈、验证码页面污染答案。
+- 不实现 Tavily / Brave / Bing Search API、自建搜索后端、网页全文抓取或长期缓存。
