-- 插件打包与构建工具
-- 插件开发与打包文档
-- 示例插件
+`LanAirApp` 是阑山桌面插件生态的对外工作区。这个目录是宿主仓库中的镜像副本，权威版本以独立 `LanAirApp` 仓库为准。
 
-目录结构：
-- `docs/`：插件开发文档、打包文档
-- `releases/`：已经打包完成、可直接分享与安装的 `.laapp` 插件包
-- `samples/`：示例插件，其中 `LanMountainDesktop.SamplePlugin` 是示例开发插件
-- `standards/`：插件标准文件与模板
-- `tools/`：插件打包与构建工具
+### 目录说明
 
-面向用户的安装流程：
-1. 将插件构建或打包为 `.laapp` 文件。
-2. 打开 `设置 -> 插件`。
-3. 点击 `打开 .laapp 插件包`。
-4. 选择插件包完成安装。
+- `docs/`：插件开发与打包文档。
+- `samples/`：示例插件与参考项目。
+- `standards/`：插件清单和目录结构约定。
+- `tools/`：插件打包与辅助工具。
 
-宿主侧的插件加载、安装、发现、解析与设置页接入逻辑，保留在 `LanMountainDesktop/plugins/`。
+### 与宿主的关系
 
-`LanMountainDesktop.PluginSdk` 仅作为插件开发 SDK 使用，提供 `IPlugin`、`IPluginContext`、清单模型与扩展注册接口。
+- 宿主程序只连接独立 `LanAirApp` 仓库中的官方市场索引。
+- 每个插件项目应在仓库根目录提供 `.laapp` 和 `README.md`。

-LanMountainDesktop 插件基于 `LanMountainDesktop.PluginSdk` 开发。
+## 中文
 
-`LanAirApp/` 负责对外发布插件开发标准、示例插件和打包工具；宿主应用内部的插件加载与解析逻辑位于 `LanMountainDesktop/plugins/`。
-`LanMountainDesktop.PluginSdk` 只提供插件作者需要依赖的开发契约，不再承载宿主侧运行时加载实现。
+使用 `LanMountainDesktop.PluginSdk` 开发插件时，至少需要准备：
 
-## 必需文件
 - `plugin.json`
-- `plugin.json` 中声明的入口程序集
-- 使用插件入口特性标记的入口类型
+- 插件入口程序集
+- 入口类
+- 本地化资源
 
-## 推荐开发流程
-1. 以 `LanAirApp/samples/LanMountainDesktop.SamplePlugin` 为起点。
-2. 修改 `plugin.json`，填写你自己的插件 `id`、名称、作者、版本和入口程序集。
-3. 实现 `IPlugin` 或继承 `PluginBase`。
-4. 通过 `IPluginContext` 注册服务、设置页和桌面组件。
-5. 将输出内容打包为 `.laapp` 文件。
+推荐从示例插件开始，先完成清单、入口、设置页和桌面组件，再逐步扩展业务逻辑。
 
-## 运行时能力
-- 插件可以注册自己的设置页。
-- 插件可以注册自己的桌面组件。
-- 插件可以注册自己的服务，并通过插件消息总线进行通信。
-- 宿主优先加载 `.laapp` 包，其次才是散装清单。
+## English
 
-## 多语言建议
-- 插件应当内置 `Localization/zh-CN.json` 与 `Localization/en-US.json`。
-- 插件界面文案、组件文案、状态文案建议统一通过插件本地化层读取。
-- 建议优先读取宿主传入的语言代码，再回退到插件默认语言。
-
-## 目录建议
-一个标准插件项目建议至少包含：
-- `plugin.json`
-- `Localization/zh-CN.json`
-- `Localization/en-US.json`
-- 插件程序集与依赖文件
-
-## 示例项目与工具
-- 示例插件：`LanAirApp/samples/LanMountainDesktop.SamplePlugin`
-- 打包工具：`LanAirApp/tools/LanMountainDesktop.PluginPackager`
-- 标准模板：`LanAirApp/standards/plugin.template.json`
+To build a plugin with `LanMountainDesktop.PluginSdk`, prepare the manifest, plugin assembly, entrance class, and localization resources first.

-LanMountainDesktop 插件的安装包格式固定为 `.laapp`。
+## 中文
 
-`LanAirApp/` 负责提供打包标准与打包工具；`.laapp` 的安装、发现和运行时加载由 `LanMountainDesktop/plugins/` 负责。
+阑山桌面插件的标准安装格式为 `.laapp`。插件项目应在仓库根目录提供：
 
-## `.laapp` 格式说明
-- 本质上是一个标准 zip 压缩包
-- 包根目录必须包含 `plugin.json`
-- 包根目录还必须包含入口程序集及其依赖
+- `.laapp` 安装包
+- `README.md`
 
-## 建议打包内容
-- `plugin.json`
-- `YourPlugin.dll`
-- 依赖程序集
-- `Localization/zh-CN.json`
-- `Localization/en-US.json`
-- 插件运行所需的其他资源文件
+官方市场索引只负责记录链接和校验信息。
 
-## 使用打包工具
-```powershell
-dotnet run --project .\LanAirApp\tools\LanMountainDesktop.PluginPackager -- --input .\path\to\plugin-output --output .\artifacts\YourPlugin.laapp --overwrite
-```
+## English
 
-## 应用内安装流程
-1. 打开 `设置 -> 插件`
-2. 点击 `打开 .laapp 插件包`
-3. 选择要安装的插件包
-4. 如果插件注册了设置页或组件，安装后重启应用
-
-## 注意事项
-- `plugin.json` 中的 `entranceAssembly` 必须能在包内找到。
-- 包内应尽量避免无关开发产物。
-- `.laapp` 是标准安装格式，建议不要对外分发散装目录。
+The standard package format is `.laapp`. Plugin repositories should keep the package and `README.md` in the repository root, while the official market index stores metadata and validation data.

-# 组件系统模块（Component System Module）
+# 组件系统说明
 
-本目录提供组件系统的模块化基础，用于支持内置组件管理与第三方扩展接入。  
-This directory provides the modular foundation for built-in component management and third-party extension integration.
+## 中文
 
-## 核心文件职责（Core Files）
-- `BuiltInComponentIds.cs`：内置组件 ID 常量（例如 `Clock`）。  
-  Built-in component ID constants (for example `Clock`).
-- `DesktopComponentDefinition.cs`：组件元数据定义（名称、类别、最小尺寸、可放置区域等）。  
-  Component metadata model (name, category, minimum size, placement permissions).
-- `ComponentPlacementRules.cs`：组件放置规则（最小尺寸、状态栏高度限制、网格边界约束）。  
-  Placement rules (minimum size, status-bar height rule, grid clamping).
-- `ComponentRegistry.cs`：组件注册中心，负责内置组件与扩展组件合并。  
-  Registry that merges built-in and extension components.
-- `Extensions/IComponentExtensionProvider.cs`：扩展提供者接口契约。  
-  Extension provider interface contract.
-- `Extensions/JsonComponentExtensionProvider.cs`：基于 JSON 的扩展加载器。  
-  JSON-based extension loader.
+`ComponentSystem/` 提供阑山桌面组件定义、注册和扩展的基础能力。
 
-## 第三方扩展契约（Extension Contract）
-- 第三方可通过实现 `IComponentExtensionProvider` 提供组件定义。  
-  Third parties can provide component definitions via `IComponentExtensionProvider`.
-- 当前内置了 JSON 提供者，运行时扫描目录：  
-  Built-in JSON provider scans at runtime:
-  - `Extensions/Components/*.json`（相对应用输出目录）  
-    `Extensions/Components/*.json` (relative to app output directory)
+### 主要职责
 
-## 加载流程（Load Flow）
-1. `ComponentRegistry.CreateDefault()` 先注册内置组件。  
-   Register built-in components first via `ComponentRegistry.CreateDefault()`.
-2. 调用 `.RegisterExtensions(...)` 合并扩展组件。  
-   Merge extension components via `.RegisterExtensions(...)`.
-3. 主窗口通过注册中心校验组件合法性与放置权限。  
-   Main window validates component identity and placement permission through the registry.
+- 管理内置组件 ID 和元数据
+- 约束组件最小尺寸与可放置区域
+- 合并内置组件与扩展组件
+- 通过 JSON 或扩展提供者接入第三方组件
 
-## JSON 清单格式（Manifest Schema）
-JSON 文件为数组，每一项代表一个组件定义。  
-The JSON file is an array, where each item represents one component definition.
+### 关键文件

-- `id`：组件唯一 ID（建议英文、稳定不变）。  
-  Unique component ID (prefer stable English key).
-- `displayName`：显示名。  
-  Display name.
-- `iconKey`：图标键（由上层 UI 解释）。  
-  Icon key resolved by UI layer.
-- `category`：组件分类。  
-  Component category.
-- `minWidthCells` / `minHeightCells`：最小占格，必须满足 `>= 1`。  
-  Minimum cell size, must satisfy `>= 1`.
-- `allowStatusBarPlacement`：是否允许放到顶部状态栏。  
-  Whether placing in top status bar is allowed.
-- `allowDesktopPlacement`：是否允许放到桌面区域。  
-  Whether placing in desktop area is allowed.
+### 扩展方式
 
-## 放置规则摘要（Placement Rules Summary）
-- 最小尺寸约束：`minWidthCells >= 1` 且 `minHeightCells >= 1`。  
-  Minimum size constraint: `minWidthCells >= 1` and `minHeightCells >= 1`.
-- 状态栏约束：状态栏组件高度必须为 `1` 格。  
-  Status bar constraint: component height must be exactly `1` cell.
-- 越界约束：所有组件坐标会被网格边界钳制（clamp）。  
-  Out-of-bounds constraint: component coordinates are clamped to grid bounds.
+- 当前默认扫描 `Extensions/Components/*.json`
+- 组件清单定义显示名、分类、最小尺寸和可放置区域
+- 主程序通过注册中心统一验证组件是否合法

-# Desktop Packaging Guide
+# 桌面端打包指南
 
-## Prerequisites
-- Install `.NET SDK 10`
-- Windows installer build only:
-  - Install `Inno Setup 6` (`ISCC.exe`)
+## 中文
 
-## Local packaging commands
+本指南说明阑山桌面的本地打包和 CI 打包流程。
+
+### 前置条件
+
+- 安装 .NET SDK 10
+- Windows 安装包需要 Inno Setup 6（`ISCC.exe`）
+
+### 本地打包命令
+
+#### Windows 安装包
 
-### Windows installer (`win-x64`)
 ```powershell
 .\scripts\package.ps1 -RuntimeIdentifier win-x64 -Version 1.0.1
 ```
 
-Output:
-- Published files: `artifacts/publish/win-x64`
-- Installer: `artifacts/installer`
+#### Linux 包
 
-### Linux package (`linux-x64`)
 ```powershell
 pwsh ./scripts/package.ps1 -RuntimeIdentifier linux-x64 -Version 1.0.1
 ```
 
-Output:
-- Published files: `artifacts/publish/linux-x64`
-- Zip package: `artifacts/packages/LanMountainDesktop-1.0.1-linux-x64.zip`
+#### macOS 包
 
-### macOS package (`osx-x64`)
 ```powershell
 pwsh ./scripts/package.ps1 -RuntimeIdentifier osx-x64 -Version 1.0.1
 ```
 
-Output:
-- Published files: `artifacts/publish/osx-x64`
-- Zip package: `artifacts/packages/LanMountainDesktop-1.0.1-osx-x64.zip`
+### 产物位置
 
-## Optional script flags
-```powershell
-# Publish only (skip Windows installer step)
-.\scripts\package.ps1 -RuntimeIdentifier win-x64 -SkipInstaller
+- 发布目录：`artifacts/publish/<rid>`
+- 安装包或压缩包：`artifacts/installer` 或 `artifacts/packages`
 
-# Publish only (skip Linux/macOS zip package step)
-pwsh ./scripts/package.ps1 -RuntimeIdentifier linux-x64 -SkipArchive
-```
+### CI 流程
 
-## Runtime dependency notes
-- Linux build does not bundle a native `libvlc` package from NuGet.
-  - Install VLC runtime on target machine, for example:
-    - Ubuntu/Debian: `sudo apt install vlc libvlc-dev`
-- macOS packaging target in CI is currently `osx-x64`.
+- 工作流文件：`.github/workflows/windows-ci.yml`
+- 日常构建会验证桌面端可编译
+- 手动触发或 `v*` 标签可生成正式包并上传到 Release
 
-## CI workflow
-- Workflow file: `.github/workflows/windows-ci.yml`
-- Workflow name: `Desktop CI`
+## English
 
-Jobs:
-- `Validate Build (Windows)` runs on every push and pull request.
-- Package flow runs on manual trigger or `v*` tag push:
-  - `Resolve Package Version` (single shared version source)
-  - `Package (Windows)` (`win-x64` installer)
-  - `Package (Linux)` (`linux-x64` zip)
-  - `Package (macOS)` (`osx-x64` zip)
-- On `v*` tags, `Attach Artifacts to GitHub Release` uploads Windows/Linux/macOS packages to the release.
+This guide covers local packaging and CI packaging for LanMountainDesktop.
 
-### Trigger manual packaging
-1. Open GitHub Actions.
-2. Choose `Desktop CI`.
-3. Click `Run workflow`.
-4. Optional: set `version` input, for example `1.0.1`.
+### Key points
 
-### Trigger by tag
-```powershell
-git tag v1.0.1
-git push origin v1.0.1
-```
+- use `scripts/package.ps1` with the target runtime identifier
+- Windows installer requires Inno Setup
+- CI can publish artifacts and attach them to GitHub Releases

 # 宿主侧插件运行时
 
-这个目录用于归档阑山桌面宿主侧的插件相关实现。
+## 中文
 
-职责范围：
-- 已安装插件的发现
-- `.laapp` 安装包安装与替换
-- 插件运行时加载
-- 插件贡献的设置页与桌面组件接入
-- 宿主侧插件设置页的安装、显示与刷新
+本目录保存阑山桌面宿主程序中的插件运行时实现。
+
+### 主要职责
+
+- 发现已安装插件
+- 安装和替换 `.laapp` 插件包
+- 加载插件程序集
+- 接入插件贡献的设置页和桌面组件
+- 在宿主设置界面中展示插件与市场信息
+
+### 市场安装优先级
+
+1. 宿主先连接 `LanAirApp/airappmarket/index.json`。
+2. 当条目同时提供 `releaseTag` 和 `releaseAssetName` 时，宿主优先按精确标签读取插件仓库的 GitHub Release 资产。
+3. 如果 Release 不存在、资产缺失、GitHub API 失败，或当前是本地工作区测试但找不到远程资产，宿主会退回 `downloadUrl` 指向的仓库根目录 `.laapp`。
+4. 插件介绍始终读取仓库根目录 `README.md`。
+5. 安装完成后只做暂存，重启后生效，不在运行时热重载市场安装插件。
+
+### 核心文件
 
-当前宿主侧核心文件：
 - `PluginLoader.cs`
 - `PluginLoadContext.cs`
-- `PluginLoaderOptions.cs`
-- `PluginLoadResult.cs`
-- `LoadedPlugin.cs`
 - `PluginRuntimeService.cs`
-- `PluginContributions.cs`
 - `PluginCatalogEntry.cs`
 - `PluginSettingsPage.axaml`
 - `PluginSettingsPage.Host.cs`
-- `MainWindow.PluginSettingsHost.cs`
-- `SettingsWindow.PluginSettingsHost.cs`
-- `MainWindow.PluginSettingsLocalization.cs`
-- `SettingsWindow.PluginSettingsLocalization.cs`
-- `MainWindow.PluginSettingsControls.cs`
-- `SettingsWindow.PluginSettingsControls.cs`
+- `PluginMarketIndexService.cs`
+- `PluginMarketInstallService.cs`
 
-说明：
-- 插件开发标准、插件打包工具、示例插件与开发文档统一放在仓库根目录下的 `LanAirApp/`
-- 宿主本体的插件加载、解析、安装与插件设置页接入逻辑统一放在 `LanMountainDesktop/plugins/`
-- `LanMountainDesktop.PluginSdk` 只保留插件作者需要引用的契约、清单模型和扩展注册接口
+### 与 `LanAirApp` 的分工
+
+- `LanAirApp` 负责插件开发文档、示例、市场索引和校验工具。
+- 宿主目录负责运行时发现、安装、加载和界面接入。
+
+## English
+
+This directory contains the host-side plugin runtime for LanMountainDesktop.
+
+### Responsibilities
+
+- discover installed plugins
+- install and replace `.laapp` packages
+- load plugin assemblies
+- integrate plugin settings pages and desktop components
+- expose market and plugin management in the host UI
+
+### Market install order
+
+1. The host reads `LanAirApp/airappmarket/index.json`.
+2. If an entry declares both `releaseTag` and `releaseAssetName`, the host first resolves the exact GitHub Release asset.
+3. If Release resolution fails, the host falls back to the repository root `.laapp` from `downloadUrl`.
+4. Plugin details always come from the repository root `README.md`.
+5. Market installs are staged and take effect after restart.

-# LanMountainDesktop
+# 阑山桌面（LanMountainDesktop）
 
-> 你的桌面，不止一面。
+## 中文
 
-`LanMountainDesktop` 是一个基于 Avalonia 的桌面壳层项目，目标不是“做一个启动器”，而是把桌面变成可编排的信息与交互空间。
+阑山桌面是一个基于 Avalonia 的桌面壳层项目。它不是单纯的启动器，而是一个可编排、可扩展、可长期演进的桌面信息空间。
 
-> ⚠️ **注意**：该项目使用 Vibe Coding，介意勿用。
-## 项目定位
-- 以网格化布局组织桌面组件，支持多页桌面与组件自由摆放。
-- 提供顶部状态栏 + 底部任务栏的桌面框架，强调信息密度与可读性平衡。
-- 通过主题色、日夜模式、玻璃视觉与动画系统，形成统一的视觉语言。
-- 通过组件注册机制与 JSON 扩展入口，让桌面能力可持续扩展。
+### 核心目标
 
-## 核心能力
-- 桌面组件系统：天气、时钟、计时器、课程表、日历、白板、音乐控制、学习环境等组件可组合使用。
-- 壁纸系统：支持图片与视频壁纸，并可在设置中实时预览。
-- 主题系统：支持日夜模式、主题色与调色联动（Monet 风格色板）。
-- 个性化设置：网格密度、状态栏间距、任务栏布局、语言与时区等可持久化配置。
-- 本地化：内置 `zh-CN` 与 `en-US` 资源。
+- 通过网格化布局管理桌面组件。
+- 提供状态栏、任务栏和多页桌面的统一外壳。
+- 通过主题、玻璃效果和动效塑造统一体验。
+- 通过组件系统和插件系统持续扩展能力。
 
-## 工程结构
-- `LanMountainDesktop/`：桌面端主程序（Avalonia）。
-- `LanMountainDesktop.RecommendationBackend/`：推荐内容后端服务（ASP.NET Core Minimal API）。
-- `docs/`：视觉与圆角等规范文档。
-- `LanMountainDesktop/ComponentSystem/`：组件定义、注册、放置规则与扩展入口。
+### 当前工程结构
 
-## 技术栈
-- .NET 10（`net10.0`）
-- Avalonia 11
-- FluentAvalonia + FluentIcons.Avalonia
-- LibVLCSharp（用于视频相关能力）
-- WebView.Avalonia（嵌入式网页组件能力）
+- `LanMountainDesktop/`：桌面主程序。
+- `LanMountainDesktop.RecommendationBackend/`：推荐内容后端。
+- `LanMountainDesktop/ComponentSystem/`：组件定义与注册系统。
+- `LanMountainDesktop/plugins/`：宿主侧插件加载、安装和设置集成。
+- `docs/`：视觉与设计规范。
+- `LanAirApp/`：插件开发资料镜像，权威版本以独立 `LanAirApp` 仓库为准。
 
-## 扩展机制（摘要）
-- 组件系统通过 `ComponentRegistry` 合并内置组件与扩展组件。
-- 运行时会扫描 `Extensions/Components/*.json`（相对应用输出目录）加载第三方组件清单。
-- 扩展契约与字段说明见组件系统文档：`LanMountainDesktop/ComponentSystem/README.md`。
+### 生态关系
 
-## 当前状态
-- 项目包含桌面端与推荐后端两个子项目，并在同一 solution 中维护。
-- 通用应用配置默认写入本地：`%LOCALAPPDATA%\LanMountainDesktop\settings.json`。
-- 启动台与桌面布局已拆分到独立文件：`%LOCALAPPDATA%\LanMountainDesktop\launcher-settings.json`、`%LOCALAPPDATA%\LanMountainDesktop\desktop-layout-settings.json`。
-- 组件配置统一写入：`%LOCALAPPDATA%\LanMountainDesktop\component-settings.json`；同类组件按实例 `componentId::placementId` 隔离存储，同时预留插件专属配置区。
-- 当前体验以 Windows 为主要目标平台。
+- 宿主程序只连接 `LanAirApp` 仓库中的官方市场索引。
+- 官方市场索引返回插件列表以及各插件项目根目录链接。
+- 插件项目根目录提供 `.laapp` 安装包和 `README.md`。
 
-## 运行说明
-运行与环境准备已拆分到独立文档：[`run.md`](./run.md)
+### 当前状态
+
+- Windows 是当前主要目标平台。
+- 已提供组件系统、插件系统、主题系统和设置系统。
+- 中文为主语言，英文为附加扩展语言。
+
+### 运行说明
+
+运行方法见 [run.md](./run.md)。
+
+## English
+
+LanMountainDesktop is an Avalonia-based desktop shell. It is designed as a composable and extensible desktop environment rather than a simple launcher.
+
+### Main goals
+
+- manage desktop widgets with a grid-based layout
+- provide a unified shell with status bar, taskbar, and multi-page desktop support
+- build a consistent experience through themes, glass effects, and motion
+- extend capabilities through the component and plugin systems

+# AirApp Market 目录说明
+
+## 中文
+
+这个目录是阑山桌面仓库里遗留的市场原型目录，只用于历史参考，不再作为官方权威市场源。
+
+### 当前结论
+
+- 官方市场源以独立 `LanAirApp` 仓库中的 `airappmarket/index.json` 为准
+- 阑山桌面程序应连接 `LanAirApp` 仓库，而不是以本目录为权威数据源
+- 如无特殊需要，不应继续向这里添加正式市场数据

-# 圆角设计规范 (Corner Radius Design System)
+# 圆角设计规范
 
-> 基于小米澎湃OS 3 (HyperOS) 设计语言
+## 中文
 
-## 设计理念
+本规范用于统一阑山桌面不同层级容器和控件的圆角尺度。
 
-澎湃OS 3 采用**"生命感美学"**设计语言，强调：
-- **全局圆角设计** - 所有界面元素均采用圆角
-- **视觉舒适统一** - 柔和、现代、细腻
-- **多级渲染** - 配合模糊混色与阴影
-- **层级分明** - 大容器使用大圆角，小元素使用小圆角
+### 基础层级
 
-## 圆角数值体系
+- Level 1：12px，小元素和图标容器
+- Level 2：16px，小型色块和紧凑控件
+- Level 3：20px，普通按钮
+- Level 4：24px，输入面板和小型容器
+- Level 5：28px，普通玻璃面板
+- Level 6：32px，强化容器
+- Level 7：36px，大容器、窗口、任务栏
 
-### 核心数值
+### 使用建议
 
-| 级别 | 圆角值 (px) | 用途 |
-|------|-------------|------|
-| **Level 0** | 0 | 特殊场景（无圆角需求） |
-| **Level 1** | 12 | 小元素、图标内边角、ListBoxItem |
-| **Level 2** | 16 | 色块按钮、小组件 |
-| **Level 3** | 20 | 普通按钮、组件预览 |
-| **Level 4** | 24 | 输入框、小型面板 |
-| **Level 5** | 28 | 面板/卡片 (glass-panel) |
-| **Level 6** | 32 | Mica 风格面板 (mica-strong) |
-| **Level 7** | 36 | 大容器 (glass-strong)、任务栏、窗口 |
+- 同层级元素保持相同圆角。
+- 大容器的圆角大于内部子面板。
+- 动态尺寸组件可按 `cellSize` 计算圆角，但仍要落在统一范围内。
 
-### 动态圆角
-
-动态圆角根据格子大小（cellSize）动态计算：
+### 动态圆角建议
 
 ```csharp
-// 小元素
-CornerRadius = Math.Clamp(cellSize * 0.35, 16, 28);
-
-// 小组件
-CornerRadius = Math.Clamp(cellSize * 0.45, 24, 44);
-
-// 大容器（任务栏/窗口）
-CornerRadius = Math.Clamp(cellSize * 0.45, 24, 44);
-```
-
-**系数参考**：
-- 系数范围：`0.35 - 0.45`
-- 最小值限制：`12 - 24 px`
-- 最大值限制：`28 - 44 px`
-
-## 组件圆角速查表
-
-### 基础控件
-
-| 控件 | 圆角值 | 代码位置 |
-|------|--------|---------|
-| Button | 20px | GlassModule.axaml |
-| ToggleSwitch | 继承系统 | - |
-| TextBox | 20px | glass-panel |
-| ComboBox | 20px | glass-panel |
-| NumberBox | 20px | glass-panel |
-
-### 容器样式类
-
-| 样式类 | 圆角值 | 说明 |
-|--------|--------|------|
-| `.glass-panel` | 28px | 普通玻璃面板 |
-| `.glass-strong` | 36px | 加强玻璃面板（任务栏） |
-| `.mica-strong` | 36px | Mica 风格面板（设置页） |
-| `.glass-overlay` | 0px | 覆盖层（无圆角） |
-
-### 特殊场景
-
-| 场景 | 圆角值 | 说明 |
-|------|--------|------|
-| 窗口整体 | 36px | 组件库/设置窗口 |
-| 窗口标题栏 | 36px | 仅顶部圆角 (`36,36,0,0`) |
-| 颜色选择器色块 | 12px | Monet 颜色/推荐色 |
-| 设置页 ListBoxItem | 12px | 导航项 |
-| 预览视口 | 12-16px | 壁纸/网格预览 |

-## 在 XAML 中使用
-
-### 直接使用固定值
-
-```xml
-<Border Classes="glass-strong" CornerRadius="36">
-    <!-- 内容 -->
-</Border>
-
-<Button CornerRadius="20">点击</Button>
-```
-
-### 使用样式类
-
-```xml
-<!-- 使用预定义的 glass-panel 样式 -->
-<Border Classes="glass-panel">
-    <TextBlock Text="面板内容" />
-</Border>
-
-<!-- 组合多个样式类 -->
-<Border Classes="glass-strong mica-strong">
-    <!-- 内容 -->
-</Border>
-```
-
-### 动态圆角（Code-Behind）
-
-```csharp
-// 根据格子大小动态计算圆角
-var cellSize = 100; // 假设格子大小
 var cornerRadius = Math.Clamp(cellSize * 0.45, 24, 44);
-
-BottomTaskbarContainer.CornerRadius = new CornerRadius(cornerRadius);
 ```
 
-## 新增控件时的圆角规范
+## English
 
-1. **确定元素层级** - 根据容器大小选择合适的级别
-2. **遵循视觉一致性** - 同层级的元素使用相同圆角
-3. **考虑内容安全区** - 圆角不应遮挡重要内容
-4. **响应式适配** - 大屏幕使用较大圆角，小屏幕使用较小圆角
+This specification keeps corner radius usage consistent across containers and controls.
 
-### 快速参考
+### Reference levels
 
-```
-新控件圆角选择流程：
-
-1. 是窗口/大容器？        → Level 7 (36px)
-2. 是面板/卡片？          → Level 5-6 (28-36px)
-3. 是按钮/输入框？        → Level 3-4 (20-24px)
-4. 是小组件/色块？        → Level 2 (16px)
-5. 是图标/小元素？        → Level 1 (12px)

-# LanMountainDesktop 视觉规范（主题色 + 毛玻璃）
+# 视觉规范
 
-## 1. 主题色应用规范
+## 中文
 
-### 1.1 颜色角色定义
+本规范用于统一阑山桌面的主题色、玻璃效果和基础视觉语义。
 
-- `Primary`（主色）：品牌主导色，用于主要操作、关键状态提示。
-- `Secondary`（辅助色）：主色的低权重变体，用于次级强调、辅助信息。
-- `Accent`（强调色）：可被用户替换的动态主题色，用于选中态、激活态、聚焦态。
-- `OnAccent`：放在强调色背景上的文本/图标颜色。
-- `SurfaceBase` / `SurfaceRaised` / `SurfaceOverlay`：基础背景、抬升层、遮罩层。
-- `TextPrimary` / `TextSecondary` / `TextMuted` / `TextAccent`：文字语义层级。
+### 颜色角色
 
-### 1.2 UI 元素映射规则
+- `Primary`：品牌主色
+- `Secondary`：辅助色
+- `Accent`：强调色与选中态主色
+- `OnAccent`：强调色背景上的文字或图标
+- `SurfaceBase` / `SurfaceRaised` / `SurfaceOverlay`：背景层级
+- `TextPrimary` / `TextSecondary` / `TextMuted` / `TextAccent`：文本层级
 
-- 主按钮、主导航选中态：`Accent` + `OnAccent`
-- 次级按钮/输入控件：`AdaptiveButtonBackgroundBrush` + `TextPrimary`
-- 页头标题：`TextPrimary`
-- 说明/辅助文本：`TextSecondary` / `TextMuted`
-- 设置页导航激活项：`AdaptiveNavItemSelectedBackgroundBrush` + `AdaptiveNavSelectedTextBrush`
+### 使用规则
 
-### 1.3 统一资源键（单一真相源）
+- 主按钮和主要导航选中态使用 `Accent + OnAccent`
+- 次级操作和输入控件优先使用语义背景色，不直接写死颜色
+- 页面层只使用资源键和语义类名，不写业务颜色常量
 
-- 主题核心：
-  - `AdaptivePrimaryBrush`
-  - `AdaptiveSecondaryBrush`
-  - `AdaptiveAccentBrush`
-  - `AdaptiveOnAccentBrush`
-- 文本：
-  - `AdaptiveTextPrimaryBrush`
-  - `AdaptiveTextSecondaryBrush`
-  - `AdaptiveTextMutedBrush`
-  - `AdaptiveTextAccentBrush`
-- 表面：
-  - `AdaptiveSurfaceBaseBrush`
-  - `AdaptiveSurfaceRaisedBrush`
-  - `AdaptiveSurfaceOverlayBrush`
+### 玻璃效果层级
 
-## 2. 毛玻璃（Glassmorphism）统一实现方案
+- `glass-overlay`：最外层遮罩
+- `glass-strong`：主要大容器
+- `glass-panel`：子区域、小面板、卡片
 
-### 2.1 分层标准
+### 可访问性
 
-- `glass-overlay`：最高层遮罩（设置页背板）
-- `glass-strong`：主内容容器（设置页主体）
-- `glass-panel`：子功能区、组件容器（网格卡片、按钮容器）
+- 正文对比度目标不低于 `4.5:1`
+- 大号文字和重点文字不低于 `3.0:1`
+- 主题服务负责对前景色做自动对比度修正
 
-### 2.2 参数标准（模拟毛玻璃，跨平台稳定）
+## English
 
-- 描边：统一去除（`BorderThickness = 0`）
-- 模糊半径资源（供样式/扩展复用）：
-  - `AdaptiveGlassPanelBlurRadius`（日 18 / 夜 22）
-  - `AdaptiveGlassStrongBlurRadius`（日 24 / 夜 28）
-- 透明度资源：
-  - `AdaptiveGlassPanelOpacity`（日 0.88 / 夜 0.92）
-  - `AdaptiveGlassStrongOpacity`（日 0.92 / 夜 0.95）
-- 背景色：由 `GlassEffectService` 基于主题色动态混合，统一下发到：
-  - `AdaptiveGlassPanelBackgroundBrush`
-  - `AdaptiveGlassStrongBackgroundBrush`
-  - `AdaptiveGlassOverlayBackgroundBrush`
+This specification defines the visual language of LanMountainDesktop, including theme roles, glass layers, and semantic color usage.
 
-## 3. 视觉一致性策略
-
-- 全局样式入口：`Styles/GlassModule.axaml`
-- 全局主题入口：`ThemeColorSystemService` + `GlassEffectService`
-- 页面侧仅使用语义资源键和 `glass-*` 类，不写硬编码颜色
-- `MainWindow` 只负责编排：切换模式、选择主题色、触发资源重算
-
-## 4. 可访问性（WCAG）
-
-### 4.1 对比度目标
-
-- 正文文本：`>= 4.5:1`
-- 大号文本 / 强调文本：`>= 3.0:1`
-
-### 4.2 实现方式
-
-- `Theme/ColorMath.cs` 提供：
-  - 相对亮度计算
-  - 对比度计算
-  - `EnsureContrast(...)` 自动修正文本前景色
-- `ThemeColorSystemService` 在生成 `TextPrimary/TextSecondary/TextMuted/NavText` 时强制走对比度校正
-
-## 5. 跨尺寸与分辨率一致性
-

+## 中文
 
-本文档详细解析了该系统的计算原理、核心指标定义、评分算法及完整的技术架构。
+本文档描述阑山桌面中噪音监测能力的基本设计目标、核心指标和实现边界。

+- 用尽量稳定的方式度量环境噪音。
+- 区分持续噪音、超阈值时长和高频打断。
+- 将结果反馈到实时界面、历史报表和专注场景中。
 
----
+### 核心指标
 
-## 1. 核心理念
+- `p50Dbfs`：持续噪音水平，反映环境底噪。
+- `overRatioDbfs`：超阈值时间占比，反映噪音覆盖时长。
+- `segmentCount`：独立噪音事件数，反映被打断频率。
 
-### 1.1 设计原则
+### 评分思路
 
-系统认为，并非所有"响声"都是一样的。对于专注力而言：
+评分从 100 分开始，依据三类惩罚项扣分：
 
-- **持续的嗡嗡声**（如嘈杂的人群）比**偶尔的掉笔声**更具破坏性
-- **频繁的打断**（如每分钟都有人说话）比**单次的大声喧哗**更让人烦躁
-- **评分与校准分离**：评分使用原始 DBFS 数据，校准仅影响显示分贝
+- 持续噪音惩罚
+- 超阈值时长惩罚
+- 打断频率惩罚
 
-因此，评分系统采用了 **多维度加权扣分制**，满分 100 分，根据环境表现进行扣分。
+常见固定参数：
 
-### 1.2 评分与校准分离
+- 帧间隔：50ms
+- 切片时长：30s
+- 评分阈值：`-50 dBFS`
+- 事件合并窗口：500ms
+- 每分钟最大容忍事件数：6
 
-项目通过"原始数据（用于评分）"与"显示数据（用于展示）"的**严格分层**，杜绝了校准值导致的评分偏差：
+### 数据流
 
-1. **评分只依赖原始 DBFS（设备输出的相对电平）**
-   - 评分的三项核心指标（`p50Dbfs`、`overRatioDbfs`、`segmentCount`）都来自原始 `dbfs` 统计
-   - "超阈时长占比"判定条件固定为：`dbfs > scoreThresholdDbfs`（阈值默认 `-50 dBFS`），与校准无关
-   - 这意味着即使用户把"显示分贝基准"调高/调低，评分侧的 `dbfs` 不会变化，因此得分与超阈时长也不会被"调参刷分"
+1. 麦克风采集音频。
+2. 计算 RMS 与 dBFS。
+3. 聚合为时间切片。
+4. 为每个切片计算统计值和评分。
+5. 写入本地历史数据。
+6. 在 UI 中展示实时状态与历史报告。
 
-2. **校准仅影响 Display dB（UI 展示口径），不进入评分链路**
-   - 校准（`baselineRms` / `baselineDb`）只用于将 `rms` 映射为 `displayDb`，用于实时显示与报告中的"噪音等级分布"等图表展示
-   - 这些展示口径变化不会反向影响评分输入，也不会改变切片摘要中的 `raw.*` 字段
+### 设计边界
 
-3. **统计报告中"超阈时长"取自 raw.overRatioDbfs**
-   - 报告里展示的"超阈时长"是对每个切片 `raw.overRatioDbfs` 按有效采样时长加权汇总得到，仍然完全基于 DBFS
-   - 相比之下，"噪音等级分布"使用的是 `display.avgDb`（校准后的显示分贝），因此它会随校准变化——这是为了更贴近用户直觉的 dB 区间划分
+- 评分使用原始统计口径，不应被显示层校准参数反向影响。
+- 历史数据只存统计值，不存原始音频。
+- 该系统用于环境质量评估，不作为专业声学测量工具。

-## 3. 数据采集层
-
-### 3.1 麦克风采集
-
-#### 3.1.1 Web Audio API 使用
-
-系统使用 Web Audio API 获取麦克风输入，构建完整的音频处理链路：
-
-```
-麦克风 → MediaStream → MediaStreamAudioSourceNode 
-       → 高通滤波器 (80Hz) → 低通滤波器 (8000Hz) 
-       → AnalyserNode (FFT Size 2048)
-```
-
-#### 3.1.2 音频滤波器配置
-
-| 滤波器类型 | 截止频率 | 作用 |
-|-----------|---------|------|
-| 高通滤波器 | 80 Hz | 过滤低频噪音（如空调嗡嗡声） |
-| 低通滤波器 | 8000 Hz | 过滤高频噪音（如电子设备啸叫） |
-
-#### 3.1.3 AnalyserNode 配置
-
-```typescript
-analyser.fftSize = 2048;           // FFT 窗口大小
-analyser.smoothingTimeConstant = 0; // 无平滑，实时响应
-```
-
-#### 3.1.4 权限处理与错误处理
-
-```typescript
-// 麦克风权限请求配置
-{
-  audio: {
-    echoCancellation: false,    // 禁用回声消除
-    noiseSuppression: false,    // 禁用降噪
-    autoGainControl: false,     // 禁用自动增益
-  },
-  video: false
-}
-```
-
-**浏览器兼容性说明：**
-- 部分浏览器/设备可能忽略上述约束设置
-- 建议在 UI 中提示用户实际生效的约束
-- 需要测试矩阵验证：Chrome/Firefox/Safari/Edge/iOS Safari/Android WebView
-
-**错误处理：**
-- `NotAllowedError` / `SecurityError` → 权限拒绝
-- `AudioContext not supported` → 浏览器不支持
-
----
-
-### 3.2 帧处理器
-
-#### 3.2.1 采样频率
-
-- **帧间隔**：50ms（约 20 fps）
-- **数据来源**：AnalyserNode.getFloatTimeDomainData()
-
-#### 3.2.2 RMS（均方根）计算
-
-RMS 是衡量音频信号强度的标准方法：
-
-**公式：**
-$$ \text{RMS} = \sqrt{\frac{1}{N} \sum_{i=1}^{N} x_i^2} $$
-
-#### 3.2.3 dBFS（分贝满刻度）转换
-
-dBFS 是数字音频的标准分贝单位，范围 -100 到 0 dB：
-
-**公式：**
-$$ \text{dBFS} = 20 \times \log_{10}(\text{RMS}) $$
-
-**范围限制：**
-- 最小值：-100 dBFS（静音）
-- 最大值：0 dBFS（满刻度）
-
-#### 3.2.4 峰值检测
-
-峰值用于检测突发噪音，在 RMS 计算过程中同时记录峰值。
-
----
-
-## 4. 数据聚合层
-
-### 4.1 切片聚合器
-
-#### 4.1.1 切片时长
-
-- **默认切片时长**：30 秒
-- **可配置范围**：≥ 1 秒
-
-#### 4.1.2 统计指标计算
-
-切片聚合器为每个切片计算以下统计指标：
-
-| 指标 | 说明 | 计算方法 |
-|------|------|---------|
-| avgDbfs | 平均分贝 | 能量平均（线性域 RMS 平均后转回 dBFS） |
-| maxDbfs | 最大分贝 | 所有帧 dBFS 的最大值 |
-| p50Dbfs | 中位数分贝 | 线性域分位数（RMS 域计算后转回 dBFS） |
-| p95Dbfs | 95分位数分贝 | 线性域分位数（RMS 域计算后转回 dBFS） |
-| overRatioDbfs | 超阈值比例 | 超阈值时长 / 采样时长 |
-| segmentCount | 事件段数量 | 独立噪音事件次数 |
-| sampledDurationMs | 采样时长 | 有效采样时间（排除缺口） |
-| gapCount | 缺口数量 | 数据缺口次数 |
-| maxGapMs | 最大缺口时长 | 最长数据缺口时长 |
-
-#### 4.1.3 能量平均计算（avgDbfs）
-
-**公式：**
-$$ \text{avgDbfs} = 20 \times \log_{10}\left(\sqrt{\frac{1}{N} \sum_{i=1}^{N} 10^{\text{dBFS}_i / 10}}\right) $$
-
-**物理意义：** 在线性域（RMS）上做平均，符合能量守恒定律
-
-#### 4.1.4 线性域分位数计算
-
-**公式：**
-$$ \text{quantileDbfs} = 20 \times \log_{10}(Q_{\text{RMS}}(p)) $$
-
-其中 $Q_{\text{RMS}}(p)$ 是 RMS 域的分位数，使用线性插值计算：
-$$ Q_{\text{RMS}}(p) = x_{\lfloor i \rfloor} \times (1 - w) + x_{\lceil i \rceil} \times w $$
-
-- $i = (n-1) \times p$
-- $w = i - \lfloor i \rfloor$
-
-**物理意义：** 在线性域（RMS）上计算分位数，符合能量统计的严谨性
-
-#### 4.1.5 超阈值比例计算（时间加权）
-
-**公式：**
-$$ \text{overRatioDbfs} = \frac{\text{超阈值时长}}{\text{采样时长}} $$
-
-**物理意义：** 使用实际时长而非帧数计算比例，更精确
-
-#### 4.1.6 事件段检测与合并算法
-
-事件段检测用于识别独立的噪音事件：
-
-**合并规则：**
-- **合并窗口**：500ms（默认）
-- 如果两次超阈值事件间隔 ≤ 500ms，合并为同一事件段
-- 否则计为新的独立事件段
-
-**示例：**
-```
-时间轴：  0ms    200ms   400ms   600ms   800ms   1000ms
-状态：    [噪音] [噪音] [安静] [噪音] [噪音] [安静]
-合并后：  └─────── 事件段1 ───────┘  └── 事件段2 ──┘
-```
-
-#### 4.1.7 显示分贝映射（校准机制）
-
-显示分贝用于用户界面展示，支持校准：
-
-**公式（有校准）：**
-$$ \text{displayDb} = \text{baselineDb} + 20 \times \log_{10}\left(\frac{\text{rms}}{\text{baselineRms}}\right) $$
-
-**公式（无校准）：**
-$$ \text{displayDb} = 20 \times \log_{10}\left(\frac{\text{rms}}{10^{-3}}\right) + 60 $$
-
-**范围限制：** 20 dB ~ 100 dB
-
-**校准流程说明：**
-1. 使用标准声源（如 60 dB 的白噪音）
-2. 测量对应的 RMS 值
-3. 设置为 baselineRms
-4. 设置对应的显示分贝为 baselineDb
-
-#### 4.1.8 缺口检测与采样时长统计
-
-**缺口阈值：** `max(1000ms, frameMs × 5)` = **1000ms**（默认）
-
-当检测到数据缺口时，会触发切片完成并记录缺口信息。
-
-#### 4.1.9 无效帧过滤
-
-低于 -90 dBFS 的帧被视为静音/无效信号，不参与统计。
-
-**常量说明：**
-- `INVALID_DBFS_THRESHOLD = -90`：统计意义上的"静音"阈值
-- `DBFS_MIN_POSSIBLE = -100`：物理最小可表示值（用于 clamp）
-- `DBFS_MAX_POSSIBLE = 0`：物理最大可表示值（用于 clamp）
-

-
-### 4.2 实时环形缓冲区
-
-#### 4.2.1 数据结构设计
-
-环形缓冲区使用固定容量数组实现，通过起始索引和当前长度管理数据。
-
-#### 4.2.2 时间窗口裁剪策略
-
-**裁剪规则：** 移除时间戳早于 `当前时间 - retentionMs` 的数据点
-
----
-
-## 5. 评分算法核心
-
-### 5.1 三大核心指标
-
-评分引擎从以下三个维度对噪音数据进行分析：
-
-#### A. 持续噪音水平 (Sustained Level)
-
-- **定义**：剔除突发噪音后的环境"底噪"水平
-- **算法**：使用时段内所有帧的中位数电平 (`p50Dbfs`)
-- **意义**：反映环境本身是否安静。如果环境中有持续的风扇声或交谈声，该指标会升高
-
-#### B. 超阈值时长占比 (Over Threshold Ratio)
-
-- **定义**：原始 `DBFS` 超过评分阈值（`scoreThresholdDbfs`）的时间比例
-- **算法**：`超阈值时长 / 采样时长`（超标判定：`dbfs > scoreThresholdDbfs`）
-- **意义**：反映环境的"纯净度"。即使是 0.1 秒的尖叫也会被精确计入，无法被平均值掩盖
-
-> **提示**：评分阈值（`scoreThresholdDbfs`，单位 dBFS）与"界面报警/提示音"使用的显示分贝阈值（`maxLevelDb`，单位 dB）不是同一个概念；前者只用于评分，后者用于判定 noisy/quiet 与提示音触发。
-
-#### C. 打断次数密度 (Interruption Density)
-
-- **定义**：单位时间内（每分钟）发生的独立噪音事件次数
-- **智能合并算法**：
-  - 系统设有 **500ms** (默认) 的合并窗口
-  - 如果两次响声间隔小于该窗口（如拉椅子的一连串声音），会被合并为 **1 次打断**
-  - 只有间隔较长的响声才会被计为新的打断
-- **意义**：反映环境的干扰频率。频繁的打断（如断断续续的说话声）比连续的噪音更易打断心流
-
-### 5.2 评分引擎
-
-#### 5.2.1 三维度评分模型
-
-评分系统从三个维度对噪音进行评估：
-
-| 维度 | 权重 | 指标 | 满扣分条件 |
-|------|------|------|-----------|
-| **持续噪音** | 40% | p50Dbfs | 中位数超过阈值 6 dBFS |
-| **超阈时长** | 30% | overRatioDbfs | 超阈时间占比 30% |
-| **打断频次** | 30% | segmentCount | 6 次/分钟 |
-
-#### 5.2.2 评分公式
-
-**总惩罚系数：**
-$$ \text{TotalPenalty} = 0.40 \times P_{\text{sustained}} + 0.30 \times P_{\text{time}} + 0.30 \times P_{\text{segment}} $$
-
-**最终得分：**
-$$ \text{Score} = 100 \times (1 - \text{TotalPenalty}) $$
-
-#### 5.2.3 惩罚系数计算
-
-##### A. 持续噪音惩罚
-
-**公式：**
-$$ P_{\text{sustained}} = \text{clamp}_{[0,1]}\left(\frac{\text{p50Dbfs} - \text{threshold}}{6}\right) $$
-
-**满扣分条件：** `p50Dbfs - threshold ≥ 6 dBFS`
-
-##### B. 超阈时长惩罚
-
-**公式：**
-$$ P_{\text{time}} = \text{clamp}_{[0,1]}\left(\frac{\text{overRatioDbfs}}{0.3}\right) $$
-
-**满扣分条件：** `overRatioDbfs ≥ 30%`
-
-##### C. 打断频次惩罚
-
-**公式：**
-$$ P_{\text{segment}} = \text{clamp}_{[0,1]}\left(\frac{\text{segmentCount} / \text{minutes}}{\text{maxSegmentsPerMin}}\right) $$
-
-**满扣分条件：** `segmentsPerMin ≥ 6 次/分钟`
-
-#### 5.2.4 权重解读
-
-- **持续噪音 (40%)**：持续底噪仍会明显拉低分数
-- **超阈时长 (30%)**：只要大部分时间安静，偶尔的噪音仍可被容忍
-- **打断频次 (30%)**：强调"被频繁打断"对心流的破坏，提升对碎片化干扰的惩罚力度
-
-#### 5.2.5 边界条件处理
-
-- DBFS 范围限制：-100 到 0 dB
-- 惩罚系数范围限制：0 到 1
-- 评分范围限制：0 到 100 分
-
-#### 5.2.6 有效时长处理
-
-优先使用采样有效时长，不存在时回退到物理时长。
-
-#### 5.2.7 评分示例
-
-**场景 1：安静环境**
-- p50Dbfs = -60 dBFS, threshold = -50 dBFS
-- overRatioDbfs = 0.05 (5%)
-- segmentCount = 1, duration = 30s
-
-```
-sustainedPenalty = clamp01((-60 - (-50)) / 6) = clamp01(-10/6) = 0
-timePenalty = clamp01(0.05 / 0.3) = 0.167
-segmentPenalty = clamp01((1/0.5) / 6) = clamp01(2/6) = 0.333
-
-TotalPenalty = 0.4×0 + 0.3×0.167 + 0.3×0.333 = 0.15
-Score = 100 × (1 - 0.15) = 85 分
-```
-
-**场景 2：嘈杂环境**
-- p50Dbfs = -45 dBFS, threshold = -50 dBFS
-- overRatioDbfs = 0.40 (40%)
-- segmentCount = 8, duration = 30s
-
-```
-sustainedPenalty = clamp01((-45 - (-50)) / 6) = clamp01(5/6) = 0.833
-timePenalty = clamp01(0.40 / 0.3) = 1.0
-segmentPenalty = clamp01((8/0.5) / 6) = clamp01(16/6) = 1.0
-
-TotalPenalty = 0.4×0.833 + 0.3×1.0 + 0.3×1.0 = 0.933
-Score = 100 × (1 - 0.933) = 6.7 分
-```

-## 7. 历史报告生成
-
-### 7.1 历史构建器
-
-#### 7.1.1 与课表关联逻辑
-
-**关联规则：**
-1. 按日期分组切片
-2. 对每个日期的每个课时，查找重叠的切片
-3. 计算该课时的平均评分
-
-#### 7.1.2 时段平均评分计算（加权平均）
-
-**公式：**
-$$ \text{avgScore} = \frac{\sum_{i} \text{score}_i \times \text{effectiveMs}_i}{\sum_{i} \text{effectiveMs}_i} $$
-
-其中：
-$$ \text{effectiveMs}_i = \text{sampledDurationMs}_i \times \frac{\text{overlapMs}_i}{\text{sliceMs}_i} $$
-
-#### 7.1.3 覆盖率计算
-
-**公式：**
-$$ \text{coverageRatio} = \frac{\text{totalMs}}{\text{periodMs}} $$
-
-**含义：** 课时内有效采样时长占课时总时长的比例
-
-#### 7.1.4 日期时间处理
-
-**时区说明：**
-- 使用本地时区
-- 内部存储使用 UTC 时间戳
-- 对外展示使用本地时间
-
-**日期格式：** `YYYY-MM-DD`
-**时间格式：** `HH:MM`
-
-#### 7.1.5 跨天课时处理
-
-如果结束时间 ≤ 开始时间，则课时跨越到次日。
-
-#### 7.1.6 报告中的图表
-
-在噪音统计报告中，您可以直观地看到这些数据：
-
-- **评分走势图**：展示了 `Score` 随时间的变化，帮助您回顾专注状态
-- **噪音等级分布**：将每一帧归类为安静/正常/吵闹/极吵，直观展示时间占比
-- **扣分归因**：直接显示上述三个维度的扣分比例，告诉您为什么分低（是因为一直吵，还是因为总被打断）
-- **打断次数密度**：展示每分钟被干扰的次数
-

-
-## 8. 流服务整合
-
-### 8.1 噪音流服务
-
-#### 8.1.1 订阅/发布模式
-
-**模式：** 观察者模式
-- 多个组件可同时订阅
-- 最后一个订阅者取消时自动停止采集
-
-#### 8.1.2 生命周期管理
-
-流服务支持启动、停止和重启操作，自动管理采集资源的生命周期。
-
-#### 8.1.3 预热帧处理
-
-**目的：** 丢弃麦克风启动后的不稳定数据（约 500ms）
-
-#### 8.1.4 设置热更新响应
-
-**需要重启的参数：**
-- frameMs
-- sliceSec
-- scoreThresholdDbfs
-- segmentMergeGapMs
-- maxSegmentsPerMin
-
-**无需重启的参数：**
-- maxLevelDb
-- showRealtimeDb
-- alertSoundEnabled
-- avgWindowSec
-- baselineDb
-
-#### 8.1.5 时间加权平均
-
-**公式：**
-$$ \text{avg} = \frac{\sum_{i} v_i \times (t_{i+1} - t_i)}{\sum_{i} (t_{i+1} - t_i)} $$
