ACU v0.1.10

新增与修复

• 新增“合盖继续运行”子菜单，复用防锁屏活动；首次配置安装仅允许固定 on/off 操作的 root 包装脚本与当前用户 sudo 免密规则。
• 管理员认证优先使用已配置的 sudo Touch ID，不可用时回退密码弹窗，不修改 PAM；修复移除授权后的重新配置判断和认证凭据衔接。
• 首次配置展示简短授权说明，手动开启时单独提示电池运行与散热注意事项；启动自动恢复不重复提示。
• 保存合盖运行偏好，退出时恢复原始电源设置但保留偏好，重启后自动恢复；手动关闭或移除授权后清除偏好，保留用户独立的防锁屏选择。
• 合盖运行与蓝牙离开保护在主菜单同步勾选，开关文案固定，不再切换为“停止…”动作。

Added and Fixed

• Add a lid-closed submenu backed by a root-owned wrapper and per-user sudo rules limited to exact on/off commands, reusing keep-awake activity.
• Prefer configured sudo Touch ID with administrator-password fallback without modifying PAM; fix reauthorization detection and credential handoff.
• Separate first-setup authorization from battery and ventilation reminders on each manual enable; automatic startup restoration shows no repeated reminder.
• Persist lid-closed preferences, restore original power settings on exit, and resume automatically on launch. Manual stop or authorization removal clears the preference while preserving independent keep-awake settings.
• Synchronize top-level checkmarks for lid-closed and Bluetooth departure protection, and keep toggle labels fixed.

ACU v0.1.9

新增与修复

• 保护模式下，外接显示器支持 DDC/CI 硬件调暗，并在内外屏硬件亮度降至 0 后叠加 20% Gamma 输出；不支持硬件亮度控制时使用软件调暗。
• 保存并恢复原始硬件亮度与 Gamma 曲线，增加进程异常退出后的持久化恢复、多屏匹配检查及显示器重配置处理。
• DDC 写入和恢复增加读回验证，修复协议包和亮度命令不一致的问题；恢复失败时保留记录供后续重试。
• 测试模拟锁屏改为 30 秒自动退出，便于验证 15 秒无操作后的调暗；增加亮度恢复来源与防锁屏模拟事件日志。
• 增加手动硬件冒烟测试，覆盖硬件与 Gamma 调暗、恢复和强杀后的跨进程恢复；默认单测跳过硬件测试。

Added and Fixed

• Support DDC/CI dimming on external monitors, combining hardware brightness 0 with 20% gamma output on built-in and external displays; use software dimming when hardware control is unavailable.
• Persist and restore original hardware brightness and gamma curves, with recovery after process termination, safer display matching and display reconfiguration handling.
• Verify DDC writes and restoration by reading values back, fix packet framing and mismatched brightness commands, and retain failed recovery records for retry.
• Extend the simulated lock-screen test to 30 seconds so the 15-second idle dimming can be checked; log brightness restoration sources and keep-awake synthetic activity.
• Add opt-in hardware smoke tests for combined dimming, restoration and recovery after a killed process; ordinary unit tests skip hardware checks.

ACU v0.1.8

新增

• 官网中文安装区左侧增加夸克网盘入口及提取码，README 使用同一永久分享；v0.1.7 已手动镜像并完成四文件回读校验。
• 正式发布后自动将原始安装包及校验和镜像到夸克，支持暂存回读校验和独立补传；Homebrew 更新拆为独立任务并支持重试。
• 增加发布维护文档及固定版本夸克 CLI 的安装、授权同步入口。启用需配置 ACU 专属网盘目录和授权。

Added

• Add a compact Quark mirror entry and passcode to the left side of the Chinese installation section and the same permanent share to the README; manually mirror v0.1.7 and verify all four files by downloading them back.
• Mirror original public release installers and checksums to Quark with staging, download verification and independent retries; run Homebrew updates independently with a recovery entry point.
• Document release operations and add pinned Quark CLI installation and authorization synchronization. Activation requires ACU directory and credential configuration.

ACU v0.1.6

新增

• 菜单栏新增“打开官网”入口，使用默认浏览器打开 https://acu.rectcircle.cn/。
• 新增面向 AI Agent 与 UI 自动化场景的中英双语产品落地页，包含真实菜单截图、原生保护界面预览及交互演示。
• 新增 Netlify 静态站点配置与 Cloudflare CNAME 橙云代理接入说明。

变更

Changed

• Recommend Homebrew on the website with all three installation and launch-allowance commands, and document manual DMG installation separately.

ACU v0.1.5

修复

• 修复真实锁屏时正常保护状态无法解除模拟锁屏的问题；认证等待不再阻塞锁屏处理，并通过系统解锁事件兜底清理。

新增

• 新增持久化分级结构化日志，覆盖 Controller、Guardian 和原生桥接关键链路，自动轮转日志文件。
• 发布草稿新增 macOS 通用 .dmg 拖拽安装包及 SHA-256，统一版本化产物命名；正式发布须用户明确授权。

Fixed

• Allow system-lock teardown from the protected state, process lock events during authentication, and use system unlock notifications to recover missed lock events.

Added

• Add persistent structured logs with severity levels and rotation across Controller, Guardian, and the native bridge.
• Include universal macOS drag-and-drop disk images and checksums in release drafts, with versioned artifact names and explicit user authorization before publication.

ACU v0.1.4

变更

• 检测到 macOS 真实锁屏后自动解除模拟锁屏，避免登录后仍被 ACU 遮罩拦住。

Changed

• ACU now dismisses its simulated lock screen when macOS enters the real lock screen, so its overlay does not remain after login.

ACU v0.1.3

中文

新增

• 新增“蓝牙离开自动模拟锁屏”：可选择已配对设备，连接稳定后布防，持续断开 3 秒后开启模拟锁屏。
• 启用功能或选择设备时主动尝试连接；解锁后恢复连接尝试，并在连接稳定后重新布防。
• 蓝牙设备列表按地址去重并展示地址，便于区分同名设备。

变更

• 已布防时使用蓝牙断开通知及时发现断连，并在 3 秒宽限期内检查连接是否恢复；通知不可用时保留轮询兜底。
• 菜单状态行展示紧凑版本号。

English

Added

• Added Bluetooth departure protection: choose a paired device, arm after a stable connection, and show the simulated lock screen after it remains disconnected for 3 seconds.
• ACU now initiates a connection when the feature is enabled or a device is selected. It resumes connection attempts after unlock and rearms after the connection stabilizes.
• Bluetooth devices are deduplicated by address, which is also displayed to distinguish devices with the same name.

Changed

• While armed, ACU uses Bluetooth disconnect notifications for prompt detection and checks for reconnection during a 3-second grace period, with polling as a fallback when notifications are unavailable.
• The menu status row now includes a compact version number.

ACU v0.1.2

Warning

Homebrew 安装后需要显式运行
/usr/bin/xattr -dr com.apple.quarantine /Applications/ACU.app，这会跳过
该应用的 Gatekeeper 首次运行检查。仅在信任本仓库及其发布产物时执行。

After installing with Homebrew, explicitly run
/usr/bin/xattr -dr com.apple.quarantine /Applications/ACU.app. This skips
Gatekeeper's first-launch assessment for the app. Only do this if you trust
this repository and its release artifacts.

中文

修复

• 修复 macOS 15 上 Wallpaper Store 的 file:// 资源无法解析，导致模拟锁屏无法展示
  当前系统背景的问题。
• 兼容 macOS 15 的 Aerial 墙纸清单、视频缓存和预览图目录，同时保留新版 macOS
  的墙纸资源路径。
• 当墙纸 Provider 为 default 或私有资源不可用时，回退到 macOS 提供的当前桌面
  图片。
• 安装与升级说明改为显式调用系统 /usr/bin/xattr，避免 Conda/Python 的同名工具
  不支持递归参数。

English

Fixed

• Fixed Wallpaper Store file:// resource parsing on macOS 15, which prevented
  the simulated lock screen from displaying the current system background.
• Added support for the macOS 15 Aerial manifest, video cache, and preview
  directories while retaining the wallpaper resource paths used by newer
  macOS versions.
• Added a fallback to the current desktop image provided by macOS when the
  wallpaper provider is default or private resources are unavailable.
• Updated installation and upgrade instructions to invoke /usr/bin/xattr
  explicitly, avoiding incompatible commands supplied by Conda or Python.

ACU v0.1.1

Warning

Homebrew 安装后需要显式移除 ACU 的 quarantine，这会跳过该应用的 Gatekeeper
首次运行检查。仅在信任本仓库及其发布产物时执行；否则应先审查源码并在本地编译。

The Homebrew flow requires explicitly removing quarantine from ACU after
installation. This skips Gatekeeper's first-launch assessment for the app.
Only do this if you trust this repository and its release artifacts;
otherwise review and build the source locally.

中文

修复

• 修复“仅阻止系统锁屏”设置未在应用重启后恢复的问题。

变更

• Homebrew Cask 改为固定版本和 SHA-256，并明确安装后移除 quarantine 的风险。
• 发布流水线会在创建 Release 后，使用实际产物版本和 SHA-256 自动更新 Cask。
• README 增加由代码 Agent 审查源码后进行本地编译的替代安装流程。

English

Fixed

• Fixed the "Prevent System Lock Only" setting not being restored after an app
  restart.

Changed

• Pinned the Homebrew Cask version and SHA-256 checksum, with an explicit
  warning about removing quarantine from the unnotarized build.
• The release workflow now updates the Cask with the released version and
  actual SHA-256 checksum after creating the GitHub Release.
• Added an alternative installation flow for reviewing the source with a code
  agent and building locally.
