+# Aligner CODEGRAPH
+
+最后更新:2026-06-28
+
+## 用途
+
+这是 Aligner 自维护的轻量工程地图,用来减少后续任务的代码定位成本和上下文重建 token。它不是完整架构文档,也不是自动生成的调用图;它只记录稳定入口、影响面、QA 入口和已保护行为。
+
+Aligner2 同时维护两类代码地图:
+
+- `codegraph`:人工维护的本文件,记录模块边界、关键入口、受保护行为、QA 入口和最后验证基线。
+- `codebase-memory`:`codebase-memory-mcp` 生成的自动代码知识图谱,保存到 `../.codebase-memory/graph.db.zst`,用于查询调用链、影响面、死代码候选和架构概览。
+
+两者不互相替代。自动图谱结果必须回读源码、测试和 QA 证据。
+
+使用规则:
+
+- 非平凡 Quick Switch 任务,先读本文件,再读节点指向的源码和 QA。
+- 本文件只做索引,不替代源码、测试和真实 QA。
+- 版本冻结时必须更新本文件,并在打 tag 前校验路径。
+- 每个节点保持短、硬、可核对;不要写成长篇说明。
+
+当前基线:
+
+- 功能系列:`0.1.x`
+- 当前可核对 tag:`v0.1.12-build20260625.2320`
+- 最近本地验收候选包:`0.1.12 / 20260625.2320`
+- 最后冻结前验证:2026-06-28,`swift build`、`swift test`、`round015-entitlement-fixture-qa.sh`、`round1-main-ui-qa.sh` 通过;主 UI QA 日志目录 `/tmp/aligner-round01-main-ui-qa-20260628_210821`。
+- 发布事实:`0.1.12` 是本地 QA 候选代码冻结 / rollback baseline;不是正式官网 release,Developer ID、notarization、staple、Gatekeeper、macOS 14 Phase C、下载源和正式发布 manifest 仍未闭环。
+- Git 根目录:`/Users/ar/Projects/Aligner2/03-O`
+- SwiftPM 根目录:`/Users/ar/Projects/Aligner2/03-O/C1.source`
+- codebase-memory 共享产物:`/Users/ar/Projects/Aligner2/03-O/.codebase-memory/graph.db.zst`
+- codebase-memory 项目名:`Users-ar-Projects-Aligner2-03-O`
+- codebase-memory 索引范围:`C1.source`、`C3.tools`
+- codebase-memory 当前规模:`3988` nodes / `12382` edges
+
+## 更新触发
+
+以下情况必须更新 CODEGRAPH:
+
+1. 用户要求“冻结版本”。
+2. 新增或修改用户可见交互。
+3. 修改 Quick Switch 状态模型、窗口枚举、Space 归属、激活、关闭、主题、视图切换或键盘导航。
+4. 新增、移动或删除核心 QA 脚本 / fixture / report 入口。
+5. 移动、重命名或拆分本文件记录的核心源码。
+6. 修复反复出现的高风险问题,并补充已保护行为。

+- Dock reopen 只负责打开 Quick Switch,复用 `Option+Tab` 的打开路径;不得改主题、视图模式或布局选择。
+- 提交窗口前先隐藏 Quick Switch overlay,再执行窗口激活。
+- Force Quit `Command+Option+Esc` 不得被 Aligner 阻挡。
+- 关闭窗口返回 `.requested` 时不做乐观删除;必须刷新验证目标是否真的消失。
+- 目标 stale / `windowNotFound` 时允许从当前展示中移除,避免用户继续点残留卡片。

+## Node: QuickSwitch.Snapshot
+
+职责:
+
+- 从原始窗口集合构造 Quick Switch 候选集。
+- 按 App 分组,按 Space / 标题 / window id 排序。

+
+已保护行为:
+
+- 最小化窗口必须展示,选中后恢复。
+- 隐藏 App 窗口不展示。
+- 全屏 App 窗口必须可发现。
+- Finder Split View / 多页签必须优先用高置信 frame / host 关系补 Space 归属。
+- No-space 窗口不得无脑归属到当前 Space;只在数据层高置信时归属。
+- 窗口排序保持稳定:Space 顺序优先,其次标题,再次 window id。

+## Node: QuickSwitch.ViewModel
+
+职责:
+
+- 把 snapshot 投影为三栏 UI 模型。
+- 生成 Space Lane、App Shelf、Waterfall 的展示数据。
+- 处理 Space filter 投影。
+- 识别“单全屏窗口 Space 直接激活”。

+- `QuickSwitchFocusPolicy.initialSelection(in:)`
+- `QuickSwitchFocusPolicy.nextSelection(from:in:direction:columnHistory:)`
+
+已保护行为:
+
+- Space filter 只影响 App Shelf + Waterfall,不过滤顶部 Space Lane。
+- 锁定 Space 后,App Shelf 只显示该 Space 下有窗口的 App。

 # Changelog
 
+## 0.1.12 / 20260625.2320
+
+- 修复 App Shelf 图标点击误触关闭的问题:图标主体点击优先打开该 App 的第一个窗口,只有明确点到关闭按钮视觉区域才进入关闭确认。
+- 过滤低置信 AX-only 普通窗口候选:非最小化、非全屏且没有高置信 Space 归属的 AX-only 残留不再进入 Quick Switch,避免 App badge 数量和 Waterfall 卡片虚高。
+- 激活明确失败时,本次投影视图会抑制失败 windowID,避免用户继续点到同一张不可激活的 stale 卡片。
+- 增强 App Shelf 鼠标 fixture 和窗口激活 fixture,覆盖 near-close 图标点击不进关闭流、激活失败目标被移除。
+
+## 0.1.11 / 20260625.1705
+
+- 优化 Finder 多页签 / CG-only 窗口激活的等待体验:交互路径增加 1.5 秒预算和阶段耗时日志,避免一次点击长时间卡在系统等待态。
+- Finder 页签循环兜底从 24 轮收敛为最多 5 轮;5 轮无法命中时快速返回失败,不再继续高耗时硬转。
+- Finder 直接 AX / WindowServer 激活后新增前台标题校验:标题不匹配时进入有预算的页签 fallback,避免把“看似激活成功但实际跳错页签”记录为成功。
+- Window activation QA 报告新增 `lastActivationDurationMilliseconds`,并补源码 guardrail 验证 5 轮循环上限和预算字段。
+
+## 0.1.10 / 20260624.2359
+
+- 修复 Quick Switch 窗口卡片点击偶发不准的问题:鼠标命中测试改用动画中的 presentation frame,避免过滤、对齐或横栏滚动动画期间点到视觉卡片却按旧位置提交。
+- 强化真实窗口激活链路:窗口级 AX 动作从 focus / raise 扩展为 focus / main / raise,并在 AX 短暂缺失或首次动作失败时重读一次目标窗口再尝试前置。
+- 激活 / 关闭服务接入 live Space resolver,和 snapshot 使用同一套 SkyLight Space 数据,降低 Finder、多页签、跨 Space 场景的错误 host fallback。
+- `appActivatedOnly` 不再作为窗口卡片精准激活成功语义;它只保留为诊断结果。
+- 修正 Obsidian 跨 Space live QA 在环境不满足时的脚本崩溃,改为明确 skipped 并记录原因。
+
+## 0.1.9 / 20260624.2019
+
+- 新增 Dock reopen 打开 Quick Switch:用户从 Dock 重新点击 / 双击 Aligner 图标时,复用 `Option+Tab` 的 Quick Switch 打开路径。
+- Dock reopen 只负责打开 Quick Switch,不改主题、视图模式或布局选择,全部沿用现有默认逻辑。
+- 增加 Dock reopen fixture QA,并纳入主 UI 回归入口;同步放宽真实 `Option+Tab` 触发 QA 的默认等待,降低事件 tap 启动时序误判。
+
+## 0.1.8 / 20260624.1311
+
+- 将 Aligner 的最低系统版本下探到 macOS 14.0,统一 SwiftPM、Info.plist、AppInfo 和 public manifest 元数据。
+- 为 `ScreenCaptureKit` 的 `includeChildWindows` 增加 macOS 14.2 可用性保护,保证 macOS 14.0 / 14.1 可编译运行。
+- 增加 macOS 14 兼容 QA 入口,并补 release manifest / release config 的最低系统版本 guardrail。
+
+## 0.1.7 / 20260622.1828
+
+- 修复 App Shelf 真实 hover 在 view-model / 截图刷新后丢失的问题:鼠标停在 App 图标上不动时,图标保持放大和上浮,Waterfall 联动保持有效。
+- 纵栏瀑布和横栏瀑布共用同一套 hover 持久化逻辑。
+- 增强 App Shelf fixture QA,新增 view-model rebuild 后 hover 仍保持的纵栏 / 横栏回归。
+
+## 0.1.6 / 20260622.1734
+
+- 修复 App Shelf hover 视觉覆盖不完整的问题:纵栏瀑布和横栏瀑布下都去掉 App 图标外侧蓝色矩形边框。
+- 保留真实 hover App 图标本身放大和轻微上浮,不恢复邻居图标跟随。
+- 增强 App Shelf fixture QA,新增横栏瀑布 case,并断言背景层、容器层、图标层边框均为 0。
+
+## 0.1.5 / 20260622.1717
+
+- 收敛 App Shelf hover 视觉:保留真实 hover App 图标放大效果,但移除图标背后的蓝色矩形底。
+- 取消邻近 App 图标视觉跟随,左右邻居不再放大、不上浮、不暴露 `magneticNeighbor`。
+- 增强 App Shelf fixture QA,验证 hover 背景透明、邻居保持普通尺寸、close button 只属于真实 hover App。
+
+## 0.1.4 / 20260622.1641
+
+- 优化 App Shelf hover 动效为 Magnetic Dock Lite:当前 App 图标放大并轻微上浮,邻近图标做轻量跟随。
+- 邻近 App 只做视觉动效,不触发 hover 语义、不显示关闭按钮、不联动 Waterfall / Space。
+- 用户开启 Reduce Motion 时禁用磁性放大动效。
+- 增强 App Shelf fixture QA,覆盖浅色 / 深色主题、邻近图标动效、hover 语义隔离和横栏瀑布回归。
+
 ## 0.1.3 / 20260620.1337
 
 - 增加 Option 两位窗口码输入过程中的 Waterfall 实时筛选反馈:第一键筛选 App 时,匹配窗口保持亮,其它 Waterfall 窗口变暗。

+# Aligner2 设计成果地图
+
+> 状态:迁移初稿
+> Owner:设计总监
+> 用途:让研发、QA、新 Agent 快速知道当前设计事实源、关键证据和不能擅自改的边界。
+
+## 1. 设计事实源
+
+| 层级 | 路径 | 用途 |
+| --- | --- | --- |
+| 最高设计规则 | `DESIGN.md` | 当前 UI / 交互 / 视觉 / 动效规则 |
+| 术语 | `GLOSSARY.md` | Space Lane、App Shelf、Waterfall 等标准说法 |
+| Round01 设计稿 | `02-P/Round01-QuickSwitch-MVP/02.ui设计稿/` | Quick Switch 初始视觉规格和图稿 |
+| Round01.1 增补 | `02-P/Round01.1-QuickSwitch-MVP2/` | Space filter、横栏、两位码、主题等增补 |
+| 设计决策日志 | `03-O/K1.业务知识/设计决策日志.md` | 长期设计决策 |
+
+## 2. 当前强规则
+
+- Quick Switch 是三栏结构:`Space Lane / App Shelf / Waterfall`。
+- App hover 或键盘聚焦时,Waterfall 应与 App 图标中心对齐;允许右侧留空,不为填满破坏对齐。
+- 真实截图优先;骨架缩略图只在权限、失败、性能或不可捕获时作为降级,不得伪装成真实截图。
+- 最小化窗口必须显示并可恢复。
+- 隐藏 App、幽灵窗口、系统浮层必须过滤。
+- 全屏 App 窗口必须可发现。
+- 系统关键窗口不能被永久遮挡。
+- 横栏 / 纵栏是当前双模式,不能随意删除。
+- 深色主题不是简单反色,需要保留已确认的暗色层次和可读性。
+- AppKit-first 是当前设计/实现边界;Waterfall、App Shelf、Window Card 不得为了省事改成全 SwiftUI 主状态重绘。
+
+## 3. 关键设计证据
+
+建议随 Aligner2 保留或索引的关键证据:
+
+- `02-P/Round01-QuickSwitch-MVP/02.ui设计稿/1.quick-switch-light-glass-v2-effect-20260527.png`
+- `02-P/Round01-QuickSwitch-MVP/02.ui设计稿/2.quick-switch-dark-v3-effect-20260527.png`
+- `01-I/02.3.产品需求-UI设计/SCR-20260526-sinj.png`
+- `01-I/02.3.产品需求-UI设计/SCR-20260526-sinj-2.png`
+- `01-I/02.3.产品需求-UI设计/SCR-20260617-pfku.png`
+- `01-I/02.3.产品需求-UI设计/SCR-20260526-srnp.png`
+- `02-P/Round01-QuickSwitch-MVP/02.ui设计稿/AppIcon-D1-BigBars-Handoff-20260604/`
+
+只作为归档索引,不作为当前设计规则:
+
+- 早期长录屏和 onboarding 截图。
+- 纯视觉参考风格图。
+- 早期三分栏 Excalidraw 草图。
+- 未被 `DESIGN.md`、当前 Round 或冻结记录继承的旧原型。
+
+## 4. 研发不得擅自修改
+
+- 不得把归档原型、竞品参考或早期 HTML 原型升级为当前需求。
+- 不得把真实截图默认降级为骨架。
+- 不得改变 Space / App / Window 关系表达。
+- 不得破坏 App Shelf 与 Waterfall 对齐。
+- 不得改变稳定排序、两位码、Space filter、横栏 / 纵栏键盘语义。
+- 不得为了实现方便改成 WebView、跨平台 UI 栈或全 SwiftUI 主绘制路径。
+- 不得用强品牌色、大面积蓝紫填充、营销页式装饰替代 macOS 原生克制感。
+
+## 5. 设计变更流程
+
+涉及 UI / 交互 / 视觉 / 文案的任务:
+
+1. 先读 `DESIGN.md` 和本文件。
+2. 开发只能提出可行性反馈或实现已确认设计。
+3. 如需改变设计规则,必须由设计总监或 Boss 明确确认。
+4. QA 按设计事实源验证,不用实现便利性替代视觉验收。

+## 2. 修复记录
+
+初次接收验证暴露出若干 QA 断言口径问题:提交 / 激活后目标窗口会被记录到 `suppressedActivationWindowIDs`,但部分 fixture 仍要求该目标窗口继续出现在当前可见卡片中。

+修正性质:
+
+- 验证提交记录、pre-commit snapshot、目标窗口抑制记录和可见卡片状态一致。
+- 不改变产品源码和用户可见行为。
+- 不把已激活后被抑制的目标窗口错误要求为仍在 Waterfall 可见。
+
+## 3. 当前判断

+- `round015-entitlement-fixture-qa.sh`:通过,报告 `03-O/C2.builds/Z-研发中间产物/qa-reports/round015-entitlement-fixture-qa.json`。

+- `round1-horizontal-waterfall-fixture-qa.sh`
+- `round1-window-index-progressive-filter-fixture-qa.sh`
+
+修正性质:提交 / 激活后目标窗口会进入 `suppressedActivationWindowIDs`,QA 断言应验证提交记录、pre-commit snapshot 和抑制记录,不应继续要求目标窗口留在当前可见卡片里。这是验收断言口径修正,不是产品行为变更。

+# Aligner2 新窗口接手指南
+
+> 用途:验证 Aligner2 是否能让新电脑、新 session、新 Agent 不依赖旧长会话接上工作。
+
+## 1. 接手目标
+
+接手者只读取 Aligner2 项目内文件,应该能回答:
+
+- 项目是什么,当前产品重点是什么。
+- 当前做到哪,哪些是已完成成果,哪些仍在进行。
+- 自己是什么角色,可以领取哪些任务,不能碰哪些东西。
+- 源码、工程地图、QA 门禁和发布规则在哪里。
+- 下一步应做什么,遇到冲突应退回给谁。
+
+## 2. 必读顺序
+
+根目录 `AGENTS.md` 是唯一入口;本指南不另设独立读取顺序。新窗口接手时按 `AGENTS.md` 的顺序执行:
+
+1. `PROJECT.md`
+2. `02-P/plan-progress.markdown`
+3. `02-P/角色协作宪章.md`
+4. `03-O/K2.项目管理/新窗口接手指南.md`
+5. `GLOSSARY.md`
+6. `INDEX.md`
+7. 就近的 `AGENTS.md`
+8. `03-O/C1.source/CODEGRAPH.md`
+9. `DESIGN.md`
+10. 当前任务相关的 `02-P/` 下有效 Round / PRD / QA / 架构文档
+
+不得从旧长会话、旧 `GTD.md` 或历史 Round TODO 直接领取活跃任务。
+
+## 3. 当前事实快照
+
+| 项 | 当前值 |
+| --- | --- |
+| 工作区 | `/Users/ar/Projects/Aligner2` |
+| Git 根目录 | `/Users/ar/Projects/Aligner2/03-O` |
+| SwiftPM 根目录 | `/Users/ar/Projects/Aligner2/03-O/C1.source` |
+| 当前产品重点 | Quick Switch / 快捷三栏 |
+| 当前迁移基线 | 旧 Aligner dirty 工作树 |
+| 最新本地候选 | `0.1.12 / 20260625.2320` |
+| 当前 tag 基线 | `v0.1.3-build20260620.1337` |
+| 人工工程地图 | `03-O/C1.source/CODEGRAPH.md` |
+| 自动代码图谱 | `03-O/.codebase-memory/graph.db.zst` |
+
+## 4. 角色领取规则
+
+- PMO:只能维护台账、事件地图、交接和风险,不碰代码。
+- 产品经理:只能维护需求、业务规则和验收口径,不碰代码和设计方案。
+- 设计总监:只能维护设计规则和设计验收,不碰源码和 QA 放行。
+- 架构师:只能维护技术边界和方案,不替产品、设计、QA 做结论。
+- 开发:只能实现已确认任务,不改需求、设计、架构边界和发布规则。
+- 代码审核员:只能审查并提出问题,不把 review 意见改成架构/需求/设计决策。
+- QA:只能验证和出证据,不改生产源码、需求或设计。
+- 发布 / 运营:只能在 QA 放行后处理包、manifest、下载源和上线证据。
+
+如果任务归属不清,回写 `plan-progress.markdown` 的 proposal / blocker,不自行开工。
+
+## 5. 接手自检命令
+
+```bash
+cd /Users/ar/Projects/Aligner2/03-O
+git status --short --branch
+git diff --check
+codebase-memory-mcp cli list_projects '{}'
+
+cd /Users/ar/Projects/Aligner2/03-O/C1.source
+swift build
+swift test
+```
+
+GUI、签名、公证、Gatekeeper、macOS 14 真机验证按 `03-O/K2.项目管理/QA成果地图.md` 决定是否运行。
+
+## 6. 不迁移的内容
+
+- 原始长会话记录。
+- `.build/`、`.swiftpm/`、DerivedData、`.DS_Store`。
+- 旧 `C2.builds/X-旧版build成果/` 和 `C2.builds/Z-研发中间产物/` 的大体积产物。
+- 未被事件地图、成果地图或台账吸收的旧口头结论。
+
+## 7. 成功判定
+
+新 Agent 只读本指南和必读顺序文件后,能独立完成:
+
+- 说明当前项目状态和迁移基线。
+- 选出自己角色可领取的任务。
+- 定位源码和 QA 入口。
+- 不依赖旧 session 继续推进一个小任务。
+
+若做不到,缺口必须回写 `02-P/plan-progress.markdown` 的 `A2-MIG-005`。
+
+## 8. 本次接手演练结果
+
+2026-06-28 已完成一次新 Agent 接手演练。结论:可接手。
+
+已验证:
+
+- 能说明 Aligner2 的迁移目的、当前产品重点、Git / SwiftPM 根目录。
+- 能识别 `plan-progress.markdown` 是唯一活跃任务入口。
+- 能说明角色边界和不可踩踏规则。
+- 能定位 `CODEGRAPH.md`、`codebase-memory`、QA 成果地图和接收验证记录。
+- 能指出外部发布条件仍未完成,不把本地接收 QA 等同正式发布。
+
+演练反馈已处理:
+
+- 统一本指南与根 `AGENTS.md` 的读取顺序。
+- 将主 UI QA 最终通过状态回写到台账和 QA 成果地图。

+# Aligner2 迁移资产清单
+
+> 状态:迁移初稿
+> 目标:说明哪些从 Aligner 迁入 Aligner2,哪些只做索引或排除。
+
+## 1. 已迁入
+
+| 类别 | 来源 | 目标 | 备注 |
+| --- | --- | --- | --- |
+| Git 历史 | `/Users/ar/Projects/Aligner/03-O/.git` | `/Users/ar/Projects/Aligner2/03-O/.git` | 使用 clone 迁入,避免复制旧 worktree 绝对路径 |
+| 当前工作树 | `/Users/ar/Projects/Aligner/03-O` | `/Users/ar/Projects/Aligner2/03-O` | 同步当前 dirty 工作树,排除 build/cache |
+| 输入资料 | `/Users/ar/Projects/Aligner/01-I` | `/Users/ar/Projects/Aligner2/01-I` | 保留研究、原点、设计参考 |
+| 过程资料 | `/Users/ar/Projects/Aligner/02-P` | `/Users/ar/Projects/Aligner2/02-P` | 保留 Round、PRD、QA、计划文档 |
+| 根文档 | `AGENTS.md`、`PROJECT.md`、`INDEX.md`、`DESIGN.md`、`GLOSSARY.md` | 同名路径 | 已更新当前入口路径 |
+
+## 2. 明确排除
+
+| 类别 | 路径 | 原因 |
+| --- | --- | --- |
+| SwiftPM 缓存 | `03-O/.build/`、`03-O/C1.source/.build/` | 可再生成,体积大 |
+| 本地构建产物 | `03-O/C2.builds/X-旧版build成果/` | 体积大,历史包不放迁移正文 |
+| 研发中间产物 | `03-O/C2.builds/Z-研发中间产物/` | QA report / trace / app 副本不作为迁移核心 |
+| 原始会话记录 | `.codex-sessionhistory/`、`.codex/session-history/` | 不搬长会话噪声,只提炼结论 |
+| 系统噪声 | `.DS_Store` | 无项目价值 |
+
+## 3. 风险说明
+
+- Aligner2 当前代码基线继承旧 Aligner 的 dirty 工作树,不是干净 tag。
+- `CHANGELOG.md` 与 Info.plist 已到 `0.1.12 / 20260625.2320`,但 Git HEAD 仍为 `v0.1.3-build20260620.1337`。
+- `C2.builds/` 被排除后,历史 DMG 不在 Aligner2 内;可回滚性应依赖源码 commit、tag、manifest、SHA256 和外部分发资产。
+- 未提交的 `CODEGRAPH.md`、Round01.5 授权代码、release 脚本等已作为当前工作树迁入,但仍需要后续提交治理。
+
+## 4. 后续建议
+
+- 在 Aligner2 中拆分一次治理提交:规则 / 文档 / CODEGRAPH / .gitignore。
+- 再拆源码提交:macOS 14、授权模型、release 脚本、Quick Switch 修复、QA 脚本。
+- 正式迁移新电脑前,至少完成一次 `swift build`、`swift test` 和 codebase-memory 索引。
