+# OpenStats
+
+macOS 14+ menu-bar system monitor. Swift 6 language mode, AppKit status item and panels
+hosting SwiftUI, no third-party dependencies. The Xcode project is generated from
+`project.yml` by XcodeGen; everything testable lives in the local Swift package.
+
+- `App/` — `main.swift` and the asset catalog.
+- `Helper/` — the privileged helper (`OpenStatsHelper`) and its launchd plist, embedded in
+  the app bundle for `SMAppService.daemon`.
+- `Packages/OpenStatsKit/Sources/SMC` — the AppleSMC user client, fan control, temperature
+  key discovery.
+- `Packages/OpenStatsKit/Sources/Metrics` — one sampler per metric and `MetricsHub`.
+- `Packages/OpenStatsKit/Sources/Cleaner` — cleanup rules, `SafetyGuard`, `CleanEngine`.
+- `Packages/OpenStatsKit/Sources/HelperShared` — the XPC protocol and maintenance commands
+  shared by the app and the helper.
+- `Packages/OpenStatsKit/Sources/OpenStatsUI` — design tokens, panel pages, settings,
+  menu-bar renderer, app controller, snapshot renderer.
+- `Packages/OpenStatsKit/Tests` — metrics, SMC decoding and cleanup safety.
+
+## Build
+
+**A full Xcode is required.** CommandLineTools does not ship the SwiftUI macro plugins.
+
+```bash
+brew install xcodegen
+make build            # Debug
+make install          # Release into /Applications
+make test             # swift test in the package
+```
+
+Builds are ad-hoc signed (`CODE_SIGN_IDENTITY: "-"` in `project.yml`). For a release,
+switch to a Developer ID identity, keep hardened runtime on, notarize, and set
+`HelperConstants.teamIdentifier` so the helper's code-signing requirement includes the team.
+
+## Sampling
+
+`MetricsHub` is an actor that runs one loop. `AppModel.demand` describes what is on screen —
+which menu-bar items are enabled, whether the panel is open and on which tab — and the hub
+samples only that: CPU always; memory and network cheaply; GPU, disk, processes, sensors and
+fans only when a visible surface needs them. Disk is read at most every 30 s, battery every
+10 s. The loop pauses on screen sleep, system sleep and session switch.
+
+Things that are easy to get wrong and are handled on purpose:
+
+- `host_processor_info` returns kernel-allocated memory; it is `vm_deallocate`d every sample.
+- `getifaddrs`' `if_data` counters are 32-bit and wrap at 4 GiB; network uses
+  `NET_RT_IFLIST2` and `if_data64`.
+- Memory follows Activity Monitor: app memory is `internal − purgeable` pages; the page size
+  comes from `host_page_size` (16 KB on Apple Silicon).
+- Process CPU time and wall time are both in mach absolute units, so their ratio needs no
+  timebase conversion.
+- Core types come from `hw.perflevelN`; logical CPUs are numbered from the lowest
+  performance level up.
+
+## SMC
+
+Temperatures are not hard-coded per chip. On first use the sampler enumerates every SMC key
+once (≈3,800 keys in about 10 ms on an M5 Max), groups `Tp*`/`Te*` as CPU, `Tg*` as GPU,
+`Tm*` as memory, `TB*` as battery and `Ts0P`/`Ts1P` as palm rest, keeps keys whose first
+reading is plausible, and samples at most 12 per group.
+
+Fans are read without privileges. Writing needs root and goes through the helper. On M5
+the mode key (`F0md`) accepts a direct write; M1–M4 first need `Ftst=1` and a pause while
+`thermalmonitord` lets go. The firmware records only manual or automatic, not who set it, so
+a fan in manual mode that OpenStats did not set is shown as controlled by another program.
+
+## Helper
+
+Registered with `SMAppService.daemon`; `RunAtLoad` so that an unclean exit is repaired at
+boot. The XPC interface is a fixed list of operations — no arbitrary commands — and each
+connection gets `setCodeSigningRequirement`. State that must be undone (manual fans, disabled
+sleep) is persisted to `/Library/Application Support/OpenStats/helper-state.plist` and
+reverted when the last client disconnects or at the next start. The helper exits after 30 s
+without clients.
+
+## Cleanup
+
+Every rule lists candidate items; every item passes `SafetyGuard` twice — at scan and again
+right before deletion, because apps start in between.
+
+- Deny by default: an item must sit strictly inside an allow-listed root under the home
+  folder, never be the root itself, contain no `..` or control characters, and still pass
+  after symlinks are resolved (resolution can only reject, never allow).
+- Under `Application Support`, only folders named like caches (`Code Cache`, `GPUCache`,
+  `CacheStorage`, …) are allowed.
+- Any path component matching a protected keyword (keychains, password managers, VPNs,
+  cookies, history, …) is rejected.
+- Reverse-DNS cache folders whose app is running are skipped; browser rules are blocked while
+  the browser runs; items modified in the last two minutes count as in use.
+
+Regenerable caches are deleted outright; user files go to the Trash. Each action is appended
+to `~/Library/Logs/OpenStats/cleanup.log` as a JSON line.
+
+## Panel
+
+A borderless, non-activating `NSPanel` under the status item, hosting SwiftUI inside
+`NSGlassEffectView` on macOS 26+ (`NSVisualEffectView` before). The SwiftUI tree is created on
+open and destroyed on close, so a hidden panel costs nothing. Height comes from measuring a
+flat, scroll-free copy of the same view; placeholders keep that height stable until data
+arrives, and the window is resized without animation because animating it makes SwiftUI
+re-lay out every frame. Charts are drawn with `Canvas`, not Swift Charts.
+
+`--snapshot <dir>` renders every panel tab, settings section and the menu bar in light and
+dark, through real `NSHostingView`s in off-screen windows — `ImageRenderer` washes out pages
+that contain bitmaps.

+# 更新日志
+
+记录 OpenStats 应用的功能新增、样式调整和问题修复，按版本与日期倒序排列。
+官网、构建与发布脚本等不影响应用本身的改动不在此记录。
+
+## 未发布
+
+### 2026-09-13
+
+#### 新增
+
+- 菜单栏显示 CPU、GPU、内存、网速、CPU 温度和风扇转速。CPU、GPU、内存可以分别选择数字、柱状图、圆环、饼图、柱状图加数字五种样式；网速两行显示，绿点上传、蓝点下载，带完整单位。
+- 下拉面板分为概览、进程、散热、防休眠、清理五页。概览页顶部是健康评分和芯片、内存、系统版本、运行时长、机型徽章，下面是 CPU 柱状历史、GPU 折线、内存面积图、磁盘、网络双线、风扇三列卡片，以及核心负载、电池环形图、高占用进程和快捷开关。
+- CPU 按超级核、性能核、能效核分组显示各核心负载；内存口径与活动监视器一致，并显示内存压力；网速读取 64 位计数器，大流量下不会回绕。
+- 温度与风扇：启动时枚举一次 SMC 键并按前缀归类，不按芯片型号硬编码，显示 CPU、GPU、内存、电池和掌托温度。
+- 按界面需要分级采样：面板收起时只采集菜单栏用到的指标，锁屏、屏幕休眠和系统睡眠时暂停。
+- 风扇调速：自动、降温、强冷、自定义四种模式。自定义模式下 CPU 达到安全温度会自动交还系统控制，应用退出或断开连接时风扇恢复自动。
+- 防休眠：屏幕保持常亮、仅系统不休眠、合盖后继续运行，可设定持续时间；使用电池且电量低于下限时自动关闭合盖运行。
+- 辅助工具：通过 SMAppService 注册，只提供设置风扇转速、切换合盖不睡眠、刷新 DNS、释放内存几个固定操作，并校验调用方签名；异常退出后下次开机自动恢复风扇与睡眠设置。
+- 清理：扫描应用缓存、日志与崩溃报告、Chrome / Edge / Brave / Arc / Firefox / Safari 缓存、Xcode 编译缓存、模拟器缓存、npm 缓存、Xcode 归档、未完成的下载、安装包和废纸篓。按类别显示大小，可展开查看具体项目；清理前二次确认，操作写入 `~/Library/Logs/OpenStats/cleanup.log`。
+- 清理的安全边界：只清理白名单目录，钥匙串、密码管理器、VPN、Cookie、历史记录一律不碰；正在运行的应用和浏览器自动跳过，执行前逐项重新校验。
+- 系统维护：一键刷新 DNS 缓存、释放内存，已安装辅助工具时直接执行，否则请求一次管理员授权。
+- 进程页按 CPU 或内存排序，辅助进程归并显示为所属应用。
+- 设置窗口：外观、登录时启动、刷新频率、温度单位、菜单栏显示项与样式、风扇安全温度、合盖运行电量下限、辅助工具安装与卸载。
+- 外观可选跟随系统、浅色、深色；macOS 26 起面板使用液态玻璃。
+- 截图命令 `OpenStats --snapshot <目录>`：用本机实时数据渲染面板、设置和菜单栏的浅色与深色截图。
+
+#### 样式
+
+- 菜单栏字号对齐常见菜单栏监控工具：标签 7pt 细体、数值 12pt 常规、网速 9pt 细体，指标之间留出更宽的间距。
+- 面板加宽为三列布局，高度按内容自动计算，常见屏幕上不需要滚动。
+- 更换应用图标，面板左上角和关于页使用同一图标。
+- 首次启动默认在菜单栏显示 CPU、内存与网速。
+
+#### 修复
+
+- 深色菜单栏上 CPU、RAM 小标签颜色过深，几乎看不清。
+- 面板打开后高度会再调整一次、内容轻微回弹，看起来在抖动；面板打开时点击菜单栏图标关闭，会立刻又被打开。
+- 风扇被其他程序设为手动模式时，误显示为由 OpenStats 控制。
+- 风扇转速、PID 等数字出现千分位分隔符，例如 1,350 RPM。

+OpenStats is a macOS menu-bar app that shows what your Mac is doing right now — per-core
+CPU load, GPU, memory pressure, network speed, disk, battery, temperatures and fans — and
+lets you act on it: spin the fans up, keep the Mac awake with the lid closed, clear caches.
+Everything is read on your own Mac. No account, no telemetry, no network access at all.

-## 为什么做 OpenStats
+## Install
 
-市面上的菜单栏监控要么功能单一，要么常驻耗电。OpenStats 的目标很简单：
+OpenStats has not had a release yet. The first one will be a `.dmg` on
+[Releases](https://github.com/gentpan/OpenStats/releases/latest), signed with a Developer ID
+certificate and notarized by Apple, followed by a Homebrew cask. Until then, build it from
+source — see [Build & run](#build--run).
 
-- **一眼看全**：点开菜单栏就是一整屏仪表盘，不用翻页、不用下拉。
+Requires macOS 14 (Sonoma) or later; the panel uses Liquid Glass on macOS 26 and later.

-### 面板
+- 菜单栏显示 CPU、GPU、内存、网速、CPU 温度和风扇转速。CPU、GPU、内存可以分别选择数字、柱状图、圆环、饼图、柱状图加数字五种样式；网速两行显示，绿点上传、蓝点下载，带完整单位。
+- 下拉面板分为概览、进程、散热、防休眠、清理五页。概览页顶部是健康评分和芯片、内存、系统版本、运行时长、机型徽章，下面是 CPU 柱状历史、GPU 折线、内存面积图、磁盘、网络双线、风扇三列卡片，以及核心负载、电池环形图、高占用进程和快捷开关。
+- CPU 按超级核、性能核、能效核分组显示各核心负载；内存口径与活动监视器一致，并显示内存压力；网速读取 64 位计数器，大流量下不会回绕。
+- 温度与风扇：启动时枚举一次 SMC 键并按前缀归类，不按芯片型号硬编码，显示 CPU、GPU、内存、电池和掌托温度。
+- 按界面需要分级采样：面板收起时只采集菜单栏用到的指标，锁屏、屏幕休眠和系统睡眠时暂停。
+- 风扇调速：自动、降温、强冷、自定义四种模式。自定义模式下 CPU 达到安全温度会自动交还系统控制，应用退出或断开连接时风扇恢复自动。
+- 防休眠：屏幕保持常亮、仅系统不休眠、合盖后继续运行，可设定持续时间；使用电池且电量低于下限时自动关闭合盖运行。
+- 辅助工具：通过 SMAppService 注册，只提供设置风扇转速、切换合盖不睡眠、刷新 DNS、释放内存几个固定操作，并校验调用方签名；异常退出后下次开机自动恢复风扇与睡眠设置。
+- 清理：扫描应用缓存、日志与崩溃报告、Chrome / Edge / Brave / Arc / Firefox / Safari 缓存、Xcode 编译缓存、模拟器缓存、npm 缓存、Xcode 归档、未完成的下载、安装包和废纸篓。按类别显示大小，可展开查看具体项目；清理前二次确认，操作写入 `~/Library/Logs/OpenStats/cleanup.log`。
+- 清理的安全边界：只清理白名单目录，钥匙串、密码管理器、VPN、Cookie、历史记录一律不碰；正在运行的应用和浏览器自动跳过，执行前逐项重新校验。
+- 系统维护：一键刷新 DNS 缓存、释放内存，已安装辅助工具时直接执行，否则请求一次管理员授权。
+- 进程页按 CPU 或内存排序，辅助进程归并显示为所属应用。
+- 设置窗口：外观、登录时启动、刷新频率、温度单位、菜单栏显示项与样式、风扇安全温度、合盖运行电量下限、辅助工具安装与卸载。
+- 外观可选跟随系统、浅色、深色；macOS 26 起面板使用液态玻璃。
+- 截图命令 `OpenStats --snapshot <目录>`：用本机实时数据渲染面板、设置和菜单栏的浅色与深色截图。
 
-- **概览仪表盘**：健康评分、芯片 / 内存 / 系统 / 运行时长徽章，CPU 柱状历史、GPU 折线、内存面积图、磁盘、网络双线、风扇、各核心负载（超级核 / 性能核 / 能效核分组）、电池环形图、高占用进程、快捷开关。
+**Style**
-- **进程**：按 CPU 或内存排序，辅助进程归并显示为所属应用。
+
-- **散热**：CPU / GPU / 内存 / 电池 / 掌托温度；风扇实时转速与调速。
+- 菜单栏字号对齐常见菜单栏监控工具：标签 7pt 细体、数值 12pt 常规、网速 9pt 细体，指标之间留出更宽的间距。
-- **防休眠**：屏幕常亮、仅系统不休眠、**合盖后继续运行**，支持定时与低电量自动关闭。
+- 面板加宽为三列布局，高度按内容自动计算，常见屏幕上不需要滚动。
+- 更换应用图标，面板左上角和关于页使用同一图标。
+- 首次启动默认在菜单栏显示 CPU、内存与网速。
+
+**Fixed**

+
+## Where the numbers show
+
+**Menu bar**
+- CPU, GPU and memory each in one of five styles — number, bars, ring, pie, or bars with a
+  number — plus network speed, CPU temperature and the fastest fan.
+- Network speed takes two rows: a green dot for upload, a blue dot for download, always with
+  its unit (`KB/s`, `MB/s`, `GB/s`).
+- Labels at 7 pt and figures at 12 pt, matching the menu-bar monitors people already use.
+  Figures are fixed-width, so the bar does not jitter as they change.
+
+<p align="center"><img src="Assets/readme/menubar-dark.png" width="600" alt="Menu bar"></p>
+
+**Panel** — click the menu-bar item.
+- **Overview.** A health score with badges for the chip, memory, macOS version, uptime and
+  model; then CPU history as bars, GPU as a line, memory, disk, network and fans in three
+  columns; per-core load grouped by core type (super, performance, efficiency); battery as a
+  ring; the busiest processes and quick switches.
+- **Processes.** Sorted by CPU or memory; helper processes are shown under their app.
+- **Thermal.** CPU, GPU, memory, battery and palm-rest temperatures, and the fans.
+- **Keep awake.** Keep the display on, keep only the system awake, or keep running with the
+  lid closed — for a set time or indefinitely.
+- **Clean.** Scan, review, clean. See [Cleanup](#cleanup).
+
+The panel sizes itself to its content and needs no scrolling on common screens. `Esc`
+closes it. Light, dark or follow the system.

+</p>
+
+## Fans and sleep
+
+| Fan mode | What it does |
 |---|---|
-| 自动 | 交还 macOS 温控 |
+| Auto | Hands the fans back to macOS |
-| 降温 | 固定在最低到最高转速的 60% |
+| Cool | Holds them at 60% between minimum and maximum speed |
-| 强冷 | 最高转速 |
+| Max | Full speed |
-| 自定义 | 滑块自由设定 |
+| Custom | A slider, anywhere in the fan's range |
 
-安全机制：自定义模式下 CPU 达到设定温度（默认 95°C）自动交还系统控制；应用退出、崩溃或断开连接时风扇自动恢复。
+In Custom, the fans are handed back to macOS the moment the CPU reaches the safety
+temperature (95 °C by default). Quitting OpenStats, or the app crashing, restores automatic
+control. Running with the lid closed switches itself off on battery below a floor you choose.
 
-### 清理与系统维护
+Both need system privileges, provided by a small helper registered with `SMAppService` and
+approved once in System Settings → General → Login Items. The helper offers a fixed set of
+operations — set a fan's target speed, return fans to auto, toggle `pmset disablesleep`,
+flush the DNS cache, purge memory — and **never runs arbitrary commands**. It checks the
+caller's code signature, restores fans and sleep when the app disconnects, and after an
+unclean exit restores them at the next boot.
 
-- **一键扫描**：应用缓存、日志与崩溃报告、浏览器缓存（Chrome / Edge / Brave / Arc / Firefox / Safari）、Xcode 编译缓存、模拟器缓存、npm 缓存、Xcode 归档、未完成的下载、安装包、废纸篓。
+## Cleanup
-- **先预览再清理**：按类别显示大小，可展开查看具体项目并在访达中定位；清理前二次确认。
-- **安全边界**：只清理白名单目录；钥匙串、密码管理器、VPN、Cookie、历史记录一律不碰；正在运行的应用和浏览器自动跳过；执行前逐项重新校验；所有操作写入 `~/Library/Logs/OpenStats/cleanup.log`。
-- **系统维护**：一键刷新 DNS 缓存、释放内存（已安装辅助工具时直接执行，否则请求一次管理员授权）。
 
-<p><img src="docs/images/cleaner-light.png" width="600" alt="清理"></p>
+- **What it scans.** App caches, logs and crash reports, browser caches (Chrome, Edge,
+  Brave, Arc, Firefox, Safari), Xcode DerivedData, simulator caches, the npm cache, Xcode
+  archives, unfinished downloads, installers and the Trash.
+- **Review first.** Sizes by category, every rule expandable to its items, a second click to
+  confirm. Caches and logs are deleted outright so the space comes back at once; downloads go
+  to the Trash. One switch sends everything to the Trash instead.
+- **Safety.** Only allow-listed folders are ever touched. Keychains, password managers,
+  VPNs, cookies and history are off limits. Caches of running apps are skipped, browsers must
+  be quit first, and every item is checked again right before it goes. Each action is logged
+  to `~/Library/Logs/OpenStats/cleanup.log`.
+- **Maintenance.** Flush the DNS cache and purge memory — through the helper if it is
+  installed, otherwise after a one-time administrator prompt.

+## Your data
 
-外观（跟随系统 / 浅色 / 深色）、登录时启动、刷新频率、温度单位、菜单栏显示项与样式、风扇安全温度、合盖模式电量下限。
+OpenStats makes **no network connections**. Metrics come from the kernel (`host_processor_info`,
+`host_statistics64`, `sysctl`), IOKit and the SMC on your own Mac. Preferences live in the
+app's user defaults and contain nothing personal. There is no analytics and no telemetry.
 
-## 技术实现
+## Build & run
 
-| 数据 | 来源 |
+Requires macOS 14+, a **full Xcode** (the SwiftUI macro plugins do not ship with
-|---|---|
+CommandLineTools) and [XcodeGen](https://github.com/yonaskolb/XcodeGen).
-| CPU | `host_processor_info`，按 `hw.perflevelN` 区分核心类型 |
-| 内存 | `host_statistics64`，口径与活动监视器一致；`kern.memorystatus_vm_pressure_level` |
-| 网络 | `sysctl(NET_RT_IFLIST2)` 读取 64 位计数器（避免 `getifaddrs` 32 位回绕） |
-| GPU | `IOAccelerator` 的 `PerformanceStatistics` |
-| 温度 / 风扇 | AppleSMC；启动时枚举全部 SMC 键按前缀归类，**不硬编码芯片型号** |
-| 进程 | `proc_pid_rusage`，CPU 时间与墙钟时间同用 mach 时间单位 |
-| 电池 | `IOPowerSources` + `AppleSmartBattery` |
-
-采集按界面需要分级：面板收起时只采菜单栏用到的指标；锁屏、屏幕休眠、系统睡眠时暂停。图表全部用 Canvas 自绘，面板关闭后立即销毁视图。
-
-## 辅助工具与安全
-
-风扇调速、“合盖后继续运行”、刷新 DNS 与释放内存需要系统权限，由 `SMAppService.daemon` 注册的辅助工具完成，首次使用时在“系统设置 › 通用 › 登录项”中批准一次。
-
-- 只暴露固定的几个操作：设置风扇目标转速、恢复自动、切换 `pmset disablesleep`、刷新 DNS、释放内存，**不提供任意命令执行**。
-- 通过 XPC 通信，并校验调用方代码签名。
-- 客户端断开时自动恢复风扇与睡眠设置；异常退出后下次开机也会恢复。
-
-## 安装
-
-尚未发布正式版本。发布后将提供经过 Developer ID 签名与 Apple 公证的 DMG。
-
-## 从源码构建
-
-需要 Xcode 16 及以上，以及 [XcodeGen](https://github.com/yonaskolb/XcodeGen)：
 
 ```bash
 brew install xcodegen
-make run                 # 生成工程、编译并启动（Debug）
+make run                  # generate the project, build Debug and launch
-make run CONFIG=Release  # Release 构建
+make install              # build Release, install into /Applications and launch
-make install             # Release 构建并安装到 /Applications 后启动
+make test                 # unit tests: metrics, SMC decoding, cleanup safety
-make test                # 单元测试
+make open                 # generate the project and open it in Xcode
-make snapshot            # 用本机实时数据渲染各页面截图到 build/snapshots
-make open                # 生成并用 Xcode 打开工程
 ```
 
-开发调试参数：
+The app is a menu-bar agent, so there is little to screenshot. Render the surfaces with
+live data instead:
 
-- `--snapshot <目录>`：输出面板、设置页、菜单栏的浅色 / 深色截图
+```bash
-- `--show-panel`：启动后展开并固定面板，用于测量面板打开时的资源占用
+build/DerivedData/Build/Products/Debug/OpenStats.app/Contents/MacOS/OpenStats --snapshot ./snapshots
-

-## 致谢
+## Distribution
 
-SMC 通信与 Apple Silicon 风扇控制流程移植自 [exelban/stats](https://github.com/exelban/stats)（MIT License），详见 [ThirdPartyNotices.md](ThirdPartyNotices.md)。
+Developer ID only, not the App Store — the sandbox forbids talking to the SMC, reading other
+apps' caches and installing a privileged helper, which is most of the feature set.
 
-## 许可证
+| What you have | What others get |
+|---|---|
+| Nothing | Ad-hoc signature — runs on your Mac only. Others see *"OpenStats is damaged"*. |
+| Developer ID certificate | Hardened runtime. Others see *"Apple cannot check it for malicious software"*. |
+| Certificate + notarization | Gatekeeper accepts it — the normal *"downloaded from the internet"* prompt. |
 
-待定。
+Before a release, set the Team ID in `HelperShared/HelperProtocol.swift` so the helper
+requires the caller to be signed by it.
+
+## Architecture
+
+- `Packages/OpenStatsKit/Sources/SMC` — SMC reads and writes, fan control, temperature
+  sensor discovery.
+- `Packages/OpenStatsKit/Sources/Metrics` — samplers for CPU, memory, network, GPU, disk,
+  battery, processes and sensors, and `MetricsHub`, which samples only what is on screen.
+- `Packages/OpenStatsKit/Sources/Cleaner` — cleanup rules, the safety guard, scanning and
+  cleaning.
+- `Packages/OpenStatsKit/Sources/HelperShared` — the XPC protocol and maintenance commands.
+- `Packages/OpenStatsKit/Sources/OpenStatsUI` — design tokens, the panel, settings and the
+  menu-bar renderer.
+- `Helper/` — the privileged helper and its launchd plist. `App/` — the entry point.
+
+More in [ARCHITECTURE.md](ARCHITECTURE.md). Every change to the app is logged, dated, in

+## 数据显示在哪里
+
+**菜单栏**
+- CPU、GPU、内存可以分别选择数字、柱状图、圆环、饼图、柱状图加数字五种样式，另外还能显示网速、
+  CPU 温度和转速最高的风扇。
+- 网速两行显示：绿点上传、蓝点下载，始终带单位（`KB/s`、`MB/s`、`GB/s`）。
+- 标签 7pt、数值 12pt，与常见的菜单栏监控工具一致；数值等宽，刷新时菜单栏不抖动。
+
+<p align="center"><img src="Assets/readme/menubar-dark.png" width="600" alt="菜单栏"></p>
+
+**面板**——点击菜单栏图标打开。
+- **概览**：健康评分，芯片、内存、系统版本、运行时长、机型徽章；CPU 柱状历史、GPU 折线、内存、
+  磁盘、网络、风扇三列卡片；按超级核、性能核、能效核分组的核心负载；电池环形图；高占用进程和快捷开关。
+- **进程**：按 CPU 或内存排序，辅助进程归并到所属应用。
+- **散热**：CPU、GPU、内存、电池、掌托温度，以及风扇。
+- **防休眠**：屏幕保持常亮、仅系统不休眠、合盖后继续运行，可定时或不限时。
+- **清理**：扫描、预览、清理，见[清理](#清理)。
+
+面板高度按内容自动计算，常见屏幕上不需要滚动；按 `Esc` 关闭。外观可选浅色、深色或跟随系统。

+
+## 风扇与睡眠
+
+| 风扇模式 | 行为 |
+|---|---|
+| 自动 | 交还 macOS 温控 |
+| 降温 | 固定在最低到最高转速之间的 60% |
+| 强冷 | 最高转速 |
+| 自定义 | 用滑块在风扇转速范围内自由设定 |
+
+自定义模式下，CPU 一旦达到安全温度（默认 95°C）就交还系统控制。退出 OpenStats 或应用崩溃时，
+风扇恢复自动。合盖运行在使用电池且电量低于你设定的下限时自动关闭。
+
+这两项需要系统权限，由一个通过 `SMAppService` 注册的小型辅助工具完成，首次使用时在
+“系统设置 › 通用 › 登录项”中批准一次。辅助工具只提供固定的几个操作：设置风扇目标转速、恢复自动、
+切换 `pmset disablesleep`、刷新 DNS 缓存、释放内存，**不执行任意命令**。它会校验调用方的代码签名，
+应用断开连接时恢复风扇与睡眠设置；异常退出后，下次开机也会恢复。
+
+## 清理
+
+- **扫描范围**：应用缓存、日志与崩溃报告、浏览器缓存（Chrome、Edge、Brave、Arc、Firefox、Safari）、
+  Xcode 编译缓存、模拟器缓存、npm 缓存、Xcode 归档、未完成的下载、安装包和废纸篓。
+- **先预览**：按类别显示大小，每条规则可展开查看具体项目，清理前再确认一次。缓存与日志直接删除，
+  空间立即释放；下载目录的内容移到废纸篓。也可以一键改为全部先移到废纸篓。
+- **安全**：只处理白名单目录。钥匙串、密码管理器、VPN、Cookie、历史记录一律不碰。正在运行的应用的缓存
+  会跳过，浏览器需要先退出，删除前每一项都会再校验一次。所有操作记录在 `~/Library/Logs/OpenStats/cleanup.log`。
+- **系统维护**：刷新 DNS 缓存、释放内存。已安装辅助工具时直接执行，否则请求一次管理员授权。
+
+<p align="center"><img src="Assets/readme/cleaner-light.png" width="600" alt="清理"></p>
+
+## 你的数据
+
+OpenStats **不发起任何网络连接**。指标来自本机的内核接口（`host_processor_info`、`host_statistics64`、
+`sysctl`）、IOKit 与 SMC。偏好设置保存在应用自己的 user defaults 中，不含个人信息。没有任何统计与上报。
+
+## 构建与运行
+
+需要 macOS 14+、**完整的 Xcode**（CommandLineTools 不含 SwiftUI 宏插件）以及
+[XcodeGen](https://github.com/yonaskolb/XcodeGen)。
+
+```bash
+brew install xcodegen
+make run                  # 生成工程，编译 Debug 并启动
+make install              # 编译 Release，安装到 /Applications 并启动
+make test                 # 单元测试：指标采集、SMC 编解码、清理安全边界
+make open                 # 生成工程并用 Xcode 打开
+```
+
+菜单栏应用没什么可截图的窗口，可以用本机实时数据渲染各个界面：
+
+```bash
+build/DerivedData/Build/Products/Debug/OpenStats.app/Contents/MacOS/OpenStats --snapshot ./snapshots
+```
+
+玻璃与半透明效果只在屏幕上存在。需要测量面板打开时的资源占用，用 `--show-panel` 启动，面板会自动展开并固定。
+
+修改 `CHANGELOG.md` 后运行 `python3 Scripts/sync_changelog.py`，更新上方的“最近更新”和活跃度图。
+
+## 分发
+
+只走 Developer ID，不上 App Store——沙盒不允许访问 SMC、读取其他应用的缓存、安装特权辅助工具，
+而这正是大部分功能。
+
+| 你拥有的 | 别人打开时看到的 |
+|---|---|
+| 什么都没有 | ad-hoc 签名，只能在你自己的 Mac 上运行。别人会看到 *“OpenStats 已损坏”*。 |
+| Developer ID 证书 | 启用 Hardened Runtime。别人会看到 *“Apple 无法检查其是否包含恶意软件”*。 |
+| 证书 + 公证 | Gatekeeper 放行，只有常规的 *“从互联网下载”* 提示。 |
+
+发布前请在 `HelperShared/HelperProtocol.swift` 中填写 Team ID，让辅助工具只接受由该团队签名的调用方。
+
+## 架构
+
+- `Packages/OpenStatsKit/Sources/SMC`——SMC 读写、风扇控制、温度传感器发现。
+- `Packages/OpenStatsKit/Sources/Metrics`——CPU、内存、网络、GPU、磁盘、电池、进程、传感器的采集器，
+  以及只采集屏幕上需要的指标的 `MetricsHub`。
+- `Packages/OpenStatsKit/Sources/Cleaner`——清理规则、安全守卫、扫描与执行。
+- `Packages/OpenStatsKit/Sources/HelperShared`——XPC 协议与系统维护命令。
+- `Packages/OpenStatsKit/Sources/OpenStatsUI`——设计 token、面板、设置窗口、菜单栏绘制。
+- `Helper/`——特权辅助工具及其 launchd 配置；`App/`——应用入口。
