+# CODEGRAPH
+
+## Stable Modules
+
+- App entry and overlay state: `src/Apptag/ContentView.swift`
+  - Reads user defaults for AppGrid display, theme, tag navigation, usage tips, and hotkeys.
+  - Owns the AppGrid full-window background rendering.
+  - Reuses the last complete AppLibrary snapshot before showing startup loading UI.
+  - Calls `AppGridCollectionView` for AppKit grid rendering.
+
+- App library snapshot assembly: `src/Apptag/AppLibraryController.swift`
+  - Scans apps, reconciles tags, runs SmartStart when needed, and assembles AppGrid/Quick Search snapshots.
+  - Keeps the most recent in-process `AppLibrarySnapshot` so newly-created overlay views can render immediately while background refresh catches up.
+
+- AppGrid collection renderer: `src/Apptag/AppGridCollectionView.swift`
+  - AppKit `NSCollectionView` implementation for grouped app layout, drag/drop, app ordering, bubbles, and usage tips overlay.
+  - Should not own full-screen AppGrid theme gradients; it receives theme only for derived glass readability.
+
+- AppGrid theme model: `src/Apptag/AppGridTheme.swift`
+  - Central source for theme IDs, localization keys, preview swatches, full-screen background gradients, derived glass tone, and edit-mode contrast tokens.
+  - Persistent key: `appGridThemeID`.
+
+- Settings surface: `src/Apptag/PreferencesView.swift`
+  - Custom SwiftUI settings tabs.
+  - Theme tab writes only `appGridThemeID`; it must not mutate tags, app ordering, or category data.
+  - Can be opened with an initial target tab from AppKit/overlay notifications.
+
+- Defaults and migrations: `src/Apptag/AppDefaults.swift`
+  - Registers first-run defaults.
+  - Migrates legacy `useDarkAppGrid=true` to `appGridThemeID=deepBlue` when no new theme key exists.
+
+- Localization: `src/Apptag/Localization/*.json`
+  - 29 language JSON files.
+  - New user-visible settings keys must be present in all files.
+
+## QA Entrypoints
+
+- `src/Scripts/theme_settings_qa.sh`
+  - Verifies 8 theme cases, Theme tab, legacy dark-grid UI removal, AppGrid-only rendering boundary, edit-mode default-theme override, migration path, and 29-language keys.
+- `src/Scripts/appgrid_startup_loading_qa.sh`
+  - Verifies AppGrid startup loading uses last-snapshot reuse and delayed spinner instead of immediately exposing empty-state loading.
+- `src/Scripts/macos14_availability_typecheck_qa.sh`
+  - Typechecks for macOS 14.0 compatibility.
+- `src/Scripts/macos14_build_metadata_qa.sh`
+  - Verifies build metadata and deployment target.
+- `src/Scripts/usage_tips_qa.sh`
+  - Verifies usage tips overlay and 29-language coverage.
+- `src/Scripts/tag_navigation_hover_scroll_qa.sh`
+  - Verifies tag hover scroll semantics remain guarded.
+- `src/Scripts/tag_double_click_preferences_qa.sh`
+  - Verifies double-clicking a tag navigation item opens Preferences on the Tags tab while preserving single-click activation, hover scroll, and long-press reorder wiring.
+
+## Protected Behavior
+
+- Theme changes are visual preferences and must not change tag data, app ordering, notes, SmartStart/category scheme, quick search, drag/drop behavior, or import/export data.
+- AppGrid startup and repeated overlay creation must not immediately show a spinner just because a new `ContentView` starts with `allApps.isEmpty`; it should first reuse the last complete in-process snapshot and only show loading after a short delay if no snapshot is available.
+- Editing mode uses a temporary runtime theme override: regardless of the stored `appGridThemeID`, editing renders as the default light glass AppGrid and restores the stored theme when edit mode exits.
+- Individual AppGrid containers must remain a consistent translucent glass surface. They may use a derived light/dark glass tone for readability, but must not receive per-theme internal gradients.
+- Edit mode controls must use the runtime rendered theme, not the stored theme, so editing stays visually identical to the default light AppGrid.
+- Deep Blue and Black use dark glass. Bright Pink, Purple, Green, Blue, and Colorful themes use light glass to keep the theme bright and readable.
+- The default theme preserves the original light AppGrid background.
+- Legacy users with `useDarkAppGrid=true` must land on the `deepBlue` theme.
+- Tag navigation single-click must keep immediate scroll behavior. Hover must keep guarded auto-scroll. Long-press must keep tag reorder behavior. Double-click may open Preferences on the Tags tab but must not replace those existing behaviors.
+
+Last updated: 2026-06-24, tag double-click opens Tags settings.

+# 8.0.0 App Grid 主题系统 TODO
+
+## 目标
+
+- 在设置页新增独立“主题”页签。
+- 提供 8 个 App Grid 背景主题:默认、深蓝、黑色、粉色、紫色、绿色、蓝色、炫彩。
+- 主题只改变 App Grid 全屏背景渐变;单个容器继续使用统一半透明玻璃面板。
+- 默认主题保持原浅色毛玻璃体验;深蓝和黑色使用深色玻璃容器,粉色、紫色、绿色、蓝色、炫彩使用浅色玻璃容器以保持明亮干净。
+- 文案覆盖 29 个语种。
+
+## 不做范围
+
+- 不新增“容器玻璃深浅”独立设置。
+- 不改变标签、拖拽、排序、Quick Search、数据导入导出、SmartStart 分类逻辑。
+- 不改变默认浅色主题的既有视觉。
+- 不在容器内部增加每个容器自己的渐变。
+
+## TODO
+
+- [x] 新增 `AppGridTheme` 统一主题模型。
+- [x] 定义 8 个主题的背景渐变 token、预览色和容器玻璃适配策略。
+- [x] 将 App Grid 背景渲染改为读取主题偏好。
+- [x] 容器玻璃按主题明暗自动适配:深蓝/黑色为暗玻璃,亮色主题为浅玻璃。
+- [x] 按用户视觉反馈二次调色:黑色改为纯黑背景;粉色、绿色、紫色、蓝色、炫彩改为更明亮且互相有辨识度的渐变。
+- [x] 编辑模式做减法:进入编辑后临时使用默认浅色毛玻璃主题,退出后恢复用户原主题。
+- [x] 设置页新增“主题”页签和 8 主题选择卡片。
+- [x] 旧 `useDarkAppGrid` 偏好迁移到 `deepBlue`。
+- [x] 补齐 29 个语种的主题文案。
+- [x] 移除旧“启用深色视图”设置入口和本地化文案。
+- [x] 新增主题设置 QA 脚本。
+- [x] 更新 changelog、TODO 和工作日志。
+- [ ] 用户视觉体验验收。

+
+## 完成标准
+
+- 默认主题和 7.9.4 的浅色 App Grid 观感一致。
+- 8 个主题切换只影响 App Grid 背景与自动玻璃适配,不影响功能行为。
+- 所有 29 个语种都能显示主题页签和主题名称,不出现裸 key。

+# 8.0.0 App Grid 主题系统工作日志
+
+## 2026-06-24
+
+### 起点
+
+- 分支:`codex/dark-glass-8.0.0`
+- 基线:`v7.9.4-build20260619.2221`
+- 目标:基于已认可方案实现 8 个高级渐变背景主题,并保留原浅色毛玻璃主题。
+- 关键约束:主题切换只改 UI;不动标签、拖拽、排序、搜索、数据和 SmartStart 功能语义。
+
+### 方案决策
+
+- 8.0.0 先做“8 个高级渐变背景主题 + 自动玻璃适配”。
+- 不做容器玻璃深浅的独立开关,降低设置复杂度和 QA 面。
+- 默认主题使用浅色玻璃容器;深蓝和黑色使用深色半透明玻璃容器;粉色、紫色、绿色、蓝色、炫彩使用浅色玻璃容器,避免亮色主题被压成暗黑系。
+- 渐变只在 App Grid 全屏背景层实现,单个容器内部不做独立渐变,避免视觉噪声。
+- 炫彩主题取样自用户提供的 Meilang logo,使用青蓝、浅青、淡紫和粉色作为背景渐变来源,并降低饱和度保证可读性。
+
+### 已完成实现
+
+- 新增 `Apptag/AppGridTheme.swift`:
+  - 主题枚举、存储 key、标题 key、背景渐变 token、预览色、玻璃适配策略。
+- 修改 `AppDefaults.swift`:
+  - 新增 `appGridThemeID` 默认值。
+  - 将旧 `useDarkAppGrid=true` 迁移到 `deepBlue`。
+- 修改 `ContentView.swift`:
+  - App Grid 背景读取当前主题。
+  - 默认主题保持原浅色视觉。
+  - 黑色主题跳过毛玻璃背板,使用 100% 纯黑全屏背景。
+  - 深蓝主题保留暗色渐变和轻暗化层。
+  - 粉色、紫色、绿色、蓝色、炫彩使用更明亮的全屏渐变,不叠加暗化层。
+- 修改 `AppGridCollectionView.swift`:
+  - 容器、标题、分隔线按主题自动选择浅色/深色玻璃适配。
+  - 深蓝和黑色为暗玻璃;亮色主题为浅玻璃。
+  - 移除 AppKit 层旧的全屏背景渐变,避免 SwiftUI/AppKit 双背景叠加。
+- 修改 `PreferencesView.swift`:
+  - 新增“主题”tab。
+  - 新增 8 个主题选择卡片和主题说明。
+  - 移除 General 页旧“启用深色视图”入口。
+- 更新 29 个 `Localization/*.json`:
+  - 新增主题 tab、说明和 8 个主题名称。
+  - 删除旧深色视图设置文案。
+- 新增 `Scripts/theme_settings_qa.sh`。
+- 新增根 `CODEGRAPH.md`,记录主题系统相关模块依赖。
+
+### 2026-06-24 视觉反馈二次调色
+
+- 用户反馈:默认和深蓝可接受;黑色需要纯黑;粉色和炫彩需要明亮、年轻;绿色需要像明亮草坪/绿树后的毛玻璃;紫色和蓝色需要与深蓝拉开差异。
+- 调整结论:
+  - 黑色:全屏背景为纯黑,不使用系统毛玻璃背板、不叠加渐变或暗化层。
+  - 粉色:改为明亮粉、蜜桃和柔白高光,面向更年轻/少女取向。
+  - 绿色:改为草坪绿、嫩绿和明亮高光,保持喜人而不沉闷。
+  - 紫色:改为浅薰衣草到高饱和紫,和深蓝明显区分。
+  - 蓝色:改为天空蓝、电光蓝和青色,和深蓝明显区分。
+  - 炫彩:回到 Meilang logo 的青蓝、浅青、淡紫、亮粉取色方向,整体变亮。
+  - 亮色主题统一改回浅色玻璃容器;深色玻璃仅保留给深蓝和黑色。
+
+### QA 记录

+
+### QA 基础设施备注
+
+- `Scripts/window_logic_qa.sh` 在本机 GUI 自动化环境中出现间歇性失败:
+  - Dock 点击或全局热键偶发未触发 overlay。
+  - Codex/输入法类 App 偶发抢前台,导致旧的 frontmost app 名断言误报。
+- 已对该脚本做两类非产品逻辑加固:
+  - Quick Search 结果坐标识别不再依赖固定窗口宽度,并在失败时输出窗口列表。
+  - 前台 app 名断言降级为诊断信息,核心仍由窗口层级断言覆盖。
+  - 启动与热键触发增加重试等待。
+- 该脚本仍建议后续单独作为 QA 基础设施任务继续稳定化;本轮主题功能不依赖其失败点。
+
+### 当前结论
+
+- 8.0.0 主题系统代码已实现。
+- 确定性 QA 已覆盖主题模型、设置入口、偏好迁移、多语种文案、构建签名、macOS 14 元数据、标签 hover、使用技巧、App 排序数据和系统 Quick Search 名称回归。
+- 下一步需要用户实际体验 8 个主题的视觉效果,再决定是否冻结和打包。
+
+### 2026-06-24 15:53 编辑模式主题对比度修正
+
+- 用户反馈:亮色主题和黑色主题进入编辑模式后,顶部按钮、说明文字、确认按钮、标签列表和页面文字可读性不足。
+- 第一版修正策略:
+  - 编辑层控件接入主题高对比 token,深色主题白字、亮色主题深字。
+- Build 更新为:`20260624.1553`。
+

+
+### 2026-06-24 16:32 编辑模式主题策略简化
+
+- 用户反馈:继续按主题适配编辑态仍然复杂,要求做减法。
+- 新策略:
+  - 用户进入编辑模式时,不管当前选择深蓝、黑色、粉色、绿色、炫彩或其他主题,App Grid 运行态渲染主题都临时切换为默认浅色毛玻璃。
+  - 不写入 `appGridThemeID`,不改变设置页选择;退出编辑模式后自动恢复用户原主题。
+  - App Grid 背景、AppKit collection renderer、编辑页顶部、标签列表、应用选择项都读取 `renderedAppGridTheme`。
+  - `theme_settings_qa.sh` 增加运行态主题 override 检查,防止编辑态重新跟随用户主题。
+- Build 更新为:`20260624.1632`。

+### 2026-06-24 17:31 App Grid 启动加载体验修复
+
+- 用户反馈:每次启动/打开 App Grid 都出现转圈等待,观感不好,且此前类似问题曾修过。
+- 根因结论:
+  - App 启动时只预热 `AppIndexer` 的进程内扫描缓存。
+  - 每次显示 App Grid 都会新建 `OverlayWindow + ContentView`,新的 `ContentView.allApps` 初始为空。
+  - 在后台 `AppLibraryController.refresh()` 返回前,空态直接显示 `ProgressView`,因此用户能看到转圈。
+  - 旧修复解决的是“缓存已热但新 ContentView 跳过 hydrate 导致 spinner 不消失”,没有解决冷启动或新面板首屏空态可见。
+- 本轮修复:
+  - `AppLibraryController` 保存最近一次完整 `AppLibrarySnapshot`。
+  - `ContentView.refreshAppsForOverlay()` / `refreshAppsForQuickSearch()` 先复用最近快照,再后台刷新。
+  - AppGrid 和编辑 AppGrid 的空态 spinner 改成 250ms 延迟显示;如果快照或扫描快速返回,不再闪现转圈。
+  - 新增 `Scripts/appgrid_startup_loading_qa.sh` 锁住快照复用与延迟 spinner 规则。

 ## In Progress
 
+- [2026-06-24] 8.0.0 App Grid 主题系统。
+  - 目标: 在设置页新增“主题”页签,提供默认、深蓝、黑色、粉色、紫色、绿色、蓝色、炫彩 8 个主题;主题只改变 App Grid 全屏背景渐变,容器保持统一半透明玻璃面板,并按主题明暗自动适配玻璃明暗。
+  - 范围: App Grid 背景、容器玻璃适配、设置页主题选择、旧 `useDarkAppGrid` 偏好迁移、29 语种主题文案、主题 QA 脚本。
+  - 不做: 不新增容器玻璃深浅独立开关;不改标签/拖拽/排序/Quick Search/数据结构功能语义;不改浅色默认主题视觉。
+  - 当前状态: 已完成代码实现、29 语种文案和确定性 QA;已按用户反馈将黑色改为纯黑,并将粉色/绿色/紫色/蓝色/炫彩改为更明亮且有辨识度的版本;等待用户视觉体验验收后决定是否继续冻结/打包。
+  - 文档: `Docs/Requirements/2026-06-24-app-grid-theme-system-todo.md`、`Docs/Requirements/2026-06-24-app-grid-theme-system-worklog.md`。

 ## Todo
