1. Reference site: https://macos.app.msh.team/
2. Reuse assets from "附件" (attachments) — icons, wallpapers, MP3s, MP4s. But wait — the only uploaded file is this requirements text file. There are no actual asset attachments (icons, wallpapers, audio, video). The doc says "必须优先复用附件中的真实图标、壁纸、音频、视频" but the upload only contains this text file.

1. The referenced asset attachments (icons, wallpapers, MP3s, MP4s) are missing. Options: (a) user uploads them, (b) I try to download from the reference site if accessible, (c) I use generated/substitute assets.
2. Scope is enormous — full macOS simulator with ~25 apps. Confirm they want the full build in one go.

1. The "原产物" attachments (icons, wallpapers, MP3s, MP4s) are missing — only the requirements text file was uploaded.
2. The reference site https://macos.app.msh.team/ is not accessible from my sandbox.

1. Assets: The doc requires reusing attached icons/wallpapers/audio/video, but none were uploaded. Should they upload them, or should I proceed with self-made/substitute assets (CSS/SVG/emoji icons, generated gradients as wallpapers, no real MP3/MP4 or synthesized audio)?
2. Given the reference site is unreachable, I'll build based on my knowledge of macOS Sonoma's design language — confirm that's OK.
3. Tech stack: doc recommends vanilla HTML/CSS/JS — confirm (the doc says no React/Vue). Since the requirement says static site that runs by double-clicking index.html, I should deliver plain HTML/CSS/JS. But note my environment has webapp-building skill for React... The user explicitly says "推荐原生 HTML5 + CSS3 + JavaScript，不要依赖 React/Vue 构建链". So vanilla it is. The website delivery rules say browser-openable deliverables go through website_version_manager. A static HTML site can be served too. I'll need to load that tool at the end.

• Option A: I craft all assets myself (SVG/CSS icons, gradient/generated wallpapers, WebAudio-synthesized sounds) — fully offline, no real MP3/MP4. (recommended)
• Option B: Wait for user to upload the asset pack.
• Option C: I search the web for open-licensed macOS-style assets.

• Option A: Full build in one pass (all apps, core depth) — recommended
• Option B: Core system first (boot, desktop, WM, Finder, settings, a few apps), then iterate.

• Show offline fallback pages (recommended, matches the doc's offline requirement)
• Include a small optional Node/Python proxy script for local use.

1. Assets: I search the web for open-licensed alternatives (macOS-style icons, wallpapers, MP3s, MP4s).
2. Scope: Full build in one pass.
3. Safari: static offline fallback pages.

1. Asset collection: Search for open-licensed assets:
   • macOS-style app icons (~30 PNGs): Could use open-source macOS icon packs. Options:
     • Use icons from open projects. There's a known project "macos-web" or similar. Actually there are several open-source macOS web clones with assets on GitHub: e.g., "playos" / "macOS Sonoma web" clones. But hot-linking is forbidden; I need to download them locally.
     • Good source: https://github.com/PuruVJ/macos-web (Svelte macOS Monterey clone) — has wallpapers.
     • Icon sources: "macosicons.com" API? Or icon packs on GitHub like "dahliaOS icons"... Hmm.
     • Actually a very practical approach: use well-known OSS repos that include macOS Big Sur style icons, e.g., https://github.com/elrumo/macOS_Big_Sur_icons_replacements (huge icon pack, CC licensed? It's a community pack). Download ~30 icons from there.
     • Wallpapers: PuruVJ/macos-web repo includes macOS wallpapers (Monterey, Big Sur, etc.) — but those are Apple copyrighted... The user explicitly asked to find open alternatives on the web, accepting the risk ("质量不可控、有版权风险" was the description but they chose it anyway).
     • Music: Kevin MacLeod (incompetech) is CC-BY — perfect, matches the doc ("6 首 Kevin MacLeod 音乐"). Download from incompetech.com.
     • Videos: Blender open movies (Big Buck Bunny etc.) CC-BY. Download 3 short clips.
   Network access: the sandbox couldn't reach macos.app.msh.team but general internet may work (web_search worked? I haven't tested). Let me test downloading from GitHub/incompetech.
2. Architecture: Vanilla HTML/CSS/JS, modular files: index.html, css/style.css (maybe split), js/fs.js, js/wm.js, js/apps.js, js/apps2.js, js/main.js as the doc suggests. All in Chinese.
3. Build order:
   • Asset download + local fallback generation.
   • Core: boot screen, lock screen, desktop, menu bar, Dock, control center, notifications, Spotlight.
   • Window manager (drag, 8-way resize, minimize, zoom, fullscreen, traffic lights).
   • Virtual file system (localStorage) + event bus.
   • Core apps: Finder, Terminal, TextEdit, Notes, Calculator, Calendar, Photos, Music, Safari, System Settings.
   • Extended apps: Launchpad, Maps, App Store, Activity Monitor, Weather, Clock, Reminders, Contacts, Stickies, Mail, Messages, FaceTime, Preview, QuickTime.
   • Persistence, theming (light/dark/auto), accessibility settings, screensaver.
   • Playwright e2e tests + screenshots.
   • Save version with website_version_manager.

• index.html
• css/base.css (variables, reset, boot, lockscreen)
• css/desktop.css (menubar, dock, control center, notifications, spotlight)
• css/windows.css (window manager, dialogs, context menus)
• css/apps.css (finder, settings, etc.)
• css/apps2.css (extended apps)
• js/util.js (helpers, event bus, storage, dom)
• js/fs.js (virtual FS)
• js/assets.js (asset manifest with fallback)
• js/wm.js (window manager + dialogs + context menus)
• js/system.js (boot, lock, power, screensaver, control center, notifications, spotlight, menubar)
• js/apps-core.js (Finder, Terminal, TextEdit, Notes, Calculator, Calendar)
• js/apps-media.js (Photos, Music, QuickTime, Preview, Safari)
• js/settings.js (System Settings app)
• js/apps-ext.js (Launchpad, Maps, AppStore, Activity Monitor, Weather, Clock)
• js/apps-ext2.js (Reminders, Contacts, Stickies, Mail, Messages, FaceTime)
• js/main.js (init, desktop icons, wiring)

• From GitHub: PuruVJ/macos-web has wallpapers. For icons, there's the "macOS_Big_Sur_icons_replacements" repo. Individual icon download via raw.githubusercontent. But I need to know exact file names. Alternatively use the repo zip? Too big (GBs).
• Alternative: many macOS web clones on GitHub include a full icon set, e.g.:
  • https://github.com/PuruVJ/macos-web (assets: wallpapers; icons are from... it uses pngs in static/assets? not sure)
  • https://github.com/Renovamen/playground-macos (React macOS clone by Renovamen) — public/img/icons/ contains many app icons! And wallpapers too. MIT license. This is a great single source: icons + wallpapers.
  • https://github.com/Zeyu-Li/MacOS-simulator ...

• vince0156/Macos ...
• "macos-sonoma-web" clones
• Let me search GitHub API for macos web clones with icon folders.

• Renovamen/playground-macos has: bear, facetime, github, launchpad, mail, safari, terminal, typora, vscode — overlapping mostly.
• Let me check another repo for trash/folder/textedit/weather/clock/stickies/preview/quicktime/activity monitor icons.

• Search GitHub for "macos icons folder trash png".
• There's the repo "Octavius8/MacOS_Web"... or "rhusiev/macos-simulator"... Let me search via GitHub code search API (may need auth). Alternatively, use the elrumo macOS_Big_Sur_icons_replacements repo — it has thousands of icons including system apps. Path structure: icons/... Let me check its tree. It's a big repo; tree API might be truncated. Let me try listing a directory.

1. Another macOS web clone repo with more icons. Let me check "vignesh07/macos-web-clone" or "satoshi7190/..." Actually a well-known one: "macOS-Sonoma-UI" ... Let me search GitHub.
2. Use the icon API from macosicons.com? Uncertain.
3. Draw missing ones as SVG myself (finder-style folder is easy; trash is easy; textedit/weather/clock/stickies/preview/quicktime/activity monitor moderately easy). I'm quite capable of drawing decent SVG icons for these.

• Monkeys Spinning Monkeys (confirmed 200)

• Carefree: .../Carefree.mp3
• Daily Beetle: .../Daily%20Beetle.mp3 Let me verify each returns 200.

• https://interactive-examples.mdn.mozilla.net/media/cc0-videos/friday.mp4
• https://interactive-examples.mdn.mozilla.net/media/cc0-videos/bee.mp4 (I think exists) Actually MDN has flower.mp4 and friday.mp4. Let me check bee.mp4 too. Alternatively W3C: https://media.w3.org/2010/05/bunny/movie_300.mp4? Or big buck bunny small: https://download.blender.org/peach/bigbuckbunny_movies/big_buck_bunny_480p_stereo.ogg (ogg). test-videos.co.uk also. I'll test MDN ones.

• big-sur-day.jpg: Catalina-like island photo (actually Big Sur coast) — usable as "Big Sur"
• monterey.jpg: galaxy/space (this is actually the old Galaxy wallpaper, not the Monterey abstract) — usable as a space one, but the doc wants "Monterey 粉紫蓝抽象壁纸" (Monterey pink-purple-blue abstract)
• w52.jpg: purple/pink abstract sunset over mountains — nice, close to Monterey/Sonoma style
• w60.jpg: tropical mountain landscape

• big-sur-day.jpg / big-sur-night.jpg: island coast day/night — good "Big Sur" pair
• monterey.jpg: galaxy — not Monterey abstract; I could rename to "galaxy.jpg" as an extra
• w52.jpg: purple-pink abstract with sun & trees — very "Monterey/Sonoma" vibe → use as default "Monterey 粉紫蓝抽象"
• w55.jpg: vibrant pink/purple/orange fantasy landscape — nice Sonoma/Ventura-like → "Ventura"
• w60.jpg: tropical green-blue landscape → "Sequoia"
• w43.jpg: anime room — not very macOS; skip
• w63.jpg: dark temple tree — skip

1. monterey.jpg → rename to galaxy.jpg? No wait — default must be "Monterey 粉紫蓝抽象". w52 → monterey.jpg (default). Existing monterey.jpg (galaxy) → rename galaxy.jpg as bonus.
2. ventura.jpg ← w55 (orange-pink vibrant)
3. big-sur.jpg ← big-sur-day (+ night variant for dark mode/auto!)
4. sequoia.jpg ← w60 (green)
5. sonoma.jpg ← need an orange abstract. Let me try a few more numbers. If none, generate a tasteful orange gradient + use big-sur-night as dark.

1. monterey.jpg ← w52.jpg (default, purple-pink abstract)
2. ventura.jpg ← w55.jpg (vibrant pink-orange landscape)
3. big-sur-day.jpg (keep) + big-sur-night.jpg (dark variant)
4. sequoia.jpg ← w60.jpg (green tropical)
5. sonoma.jpg ← generate orange/red abstract gradient
6. galaxy.jpg ← old monterey.jpg (bonus)

1. folder.png — macOS blue folder. I'll draw as SVG then rasterize to PNG at 256px for consistency (or keep SVG; browsers render SVG fine in <img>). I'll use SVG files directly — crisp at all sizes.
2. trash.svg / trash-full.svg
3. textedit.svg — white paper with pencil (macOS TextEdit icon)
4. weather.svg — sun + cloud
5. clock.svg — white clock face
6. stickies.svg — yellow sticky note
7. preview.svg — magnifier over photo
8. quicktime.svg — blue Q
9. activitymonitor.svg — green ECG line on dark rounded square
10. txt.svg — document icon
11. avatar.svg — astronaut

1. folder.svg — macOS blue folder
2. trash.svg — wire mesh trash (simplified: gray gradient bin)
3. trash-full.svg — same with paper
4. textedit.svg — white doc + pencil
5. weather.svg — sun behind cloud
6. clock.svg — clock face
7. stickies.svg — yellow note
8. preview.svg — magnifier + photo
9. quicktime.svg — blue "Q"
10. activitymonitor.svg — dark square + green pulse line
11. txt.svg — text document
12. avatar.svg — astronaut helmet
13. pdf.svg — maybe for preview

1. weather.svg failed to render — there's an error in the SVG. Probably the <rect ... rx="17"/> inside the <g fill="url(#cl)"> is fine... Let me check: the issue might be that radialGradient with cx="0.5" cy="0.5" r="0.5"... that should be fine. Let me look — ah, I see: in weather.svg I have <rect x="92" y="158" width="120" height="34" rx="17"/> — fine. Hmm, maybe XML issue: unescaped something? Let me validate the file.

• Storage: macos.settings, macos.fs, macos.desktop, macos.finder, macos.notes, macos.calendar, macos.reminders, macos.contacts, macos.stickies, macos.mail, macos.messages, macos.appstore, macos.weather, macos.clock etc. Each with JSON parse fallback.
• FS: object tree: {type:'dir', children:{}} / {type:'file', content:'', mime:''} / apps as {type:'app', appId:'safari'}. Paths like /Users/guest/Desktop/welcome.txt.
• Event bus: Bus.on('fs:changed', ...).
• WM: window objects with el, appId, title, rect, state (normal/zoomed/fullscreen/minimized), zIndex management, focus events, menu updates.
• Apps registry: Apps.register({id, name, icon, minW, minH, singleton, open(args)}).

Settings shape (macos.settings):

FS structure:

{ '': dir, children: { 'Users': { children: { 'guest': { children: { 'Desktop': {...}, 'Documents':..., 'Downloads':..., 'Pictures':..., 'Music':..., 'Applications':..., '.Trash':... } } } } } }

WM:

• WM.open(appId, opts) → creates window via app's render.
• Window: header with traffic lights, icon, title; content div; resize handles (n,s,e,w,ne,nw,se,sw).
• States: normal rect, prevRect for zoom/fullscreen restore, isZoomed, isFullscreen, isMinimized.
• z-index counter; focus sets active; inactive class reduces contrast.
• Fullscreen: fixed 0,0 100vw/100vh, radius 0; menubar & dock auto-hide; hover top edge shows menubar.
• Double-click titlebar: zoom toggle. Zoom rect = viewport minus menubar (30px) minus dock area if dock visible at bottom (leave ~dockSize+16 gap when position=bottom and not autohide... real macOS zoom avoids dock).
• Ctrl+Cmd+F toggles fullscreen on active window.
• Traffic light colors; hover reveals symbols (×, −, +).
• Minimize: window hidden; dock click restores.
• Modal/alert/confirm: UI.alert({title,msg,buttons}) returns promise.
• Context menu: UI.menu(items, x, y) with submenu support, disabled items, checkmarks, separators.

Menubar:

Dock:

• Glass bar, icons magnify on hover with neighbor interpolation (classic macOS effect using mouse x distance).
• Running dots; click behavior; right-click per-app menu (options: 退出 etc.) and dock background right-click menu (自动隐藏, 位置, 设置).
• Positions bottom/left/right with autohide + hot zone (2px strip) to reveal. Use mouseenter on hot zone + leave on dock; avoid timer race by immediate show and delayed hide with cancellation.
• Trash at end; drag? Not required. Right-click trash: 清空废纸篓.

Control center:

Notification center:

Spotlight:

Screensaver:

Boot/lock/power:

• Boot: black screen, white apple logo (SVG), progress bar 2.3s ease-out, then lock screen.
• Lock: wallpaper + blur/dark; date + big time; avatar + 客人用户 + hint; click/Enter → password stage (if enabled) else unlock. Unlock animation.
• Apple menu: 关机 (black screen "已关机 / 点按屏幕以开机"), 重新启动 (boot again), 锁定屏幕， 注销 (lock), 睡眠 (black screen, any key wakes to lock).
• Power off: click screen → boot.

Apps (25): as specced. I'll implement each with real functionality but pragmatic depth.

• Finder: sidebar (favorites + locations), toolbar (back/forward, breadcrumb, view toggle icon/list, sort dropdown, new folder, search field), content grid/list, selection (single/multi via cmd/shift), double-click open, context menu (open, get info, rename, duplicate?, copy/cut/paste, move to trash), drag files to folders to move, rename inline, get info modal, trash restore/empty. Persist view+sort per folder (or global).
• Terminal: prompt guest@MacBook-Pro cwd %; commands help,pwd,ls,cd,cat,touch,mkdir,rm,mv,cp,clear,date,whoami,uname,open,echo,history? Keep a textarea-free approach: contenteditable? Simpler: input line at bottom + output div. Path resolution relative to cwd with fs.
• TextEdit: open file (txt/md/rtf/log), plain textarea editing, title shows name + "— 已编辑", save Cmd+S / menu, save-as dialog (choose folder+name via prompt-like modal), close confirm if dirty.
• Notes: 3-pane (folders? keep 2-pane: list + editor). Search, add, delete; title from first line; autosave with debounce; updated time.
• Calculator: dark UI, 0 spans 2 cols, ops, %, ±, AC/C, keyboard support, chained ops, div-by-zero → "错误"/"不是数字" display (macOS shows "错误").
• Calendar: month grid, prev/next, today highlight, other-month dimmed; click day → events below; add (title+time), delete; persist; dot markers.
• Photos: grid of wallpapers + video posters? Use the 7 wallpapers as album; lightbox with prev/next/counter/esc/arrows.
• Music: list 6 tracks w/ durations; play/pause/prev/next/seek/volume; highlight current; auto-advance; error state if load fails (fallback message).
• QuickTime: 3 videos playlist; play/pause, seek bar, volume, time display, prev/next, fullscreen (requestFullscreen on container), error state.
• Preview: opens images (wallpapers/fs images?) and txt/pdf-ish virtual files; toolbar with zoom in/out, rotate (for images), page info for pdf (fake 1 page), error for unsupported.
• Safari: toolbar back/fwd/reload, address bar (URL or search), start page with favorites grid; built-in pages: weather (macos://weather), news (macos://news), baike/wiki (macos://baike), repo (macos://github); external http(s) → offline page with "在新标签页打开" (window.open) since no proxy; history per session; loading state (progress bar); search engine setting (bing/baidu) — search navigates to bing/baidu URL → shows offline page (can't load cross-origin in iframe due to X-Frame-Options... Actually loading bing in iframe will be blocked. So per offline decision: external URLs → designed offline page with "在新标签页打开"). Also bookmarks add.
• System Settings: full sidebar with all listed panes, search filter; each pane functional:
  • Wi-Fi: toggle + network list (fake known networks, connect state)
  • 蓝牙： toggle + device list
  • 网络： status info
  • VPN: toggle + status
  • 通知： per-app allow toggles
  • 声音： volume slider, output, alert sound choice, mute
  • 专注模式： toggle + schedule-ish
  • 关于本机： system info (macOS 网页版 version, chip "Apple M4 Web", memory, serial) + 软件更新 button
  • 软件更新： check → "已是最新版本" with spinner
  • 储存空间： bar showing usage computed from fs JSON size + assets
  • 日期与时间： 24h toggle, timezone select, current time, auto set
  • 语言与地区： language select （中文/English — keep 中文 only + note), region, first day of week
  • 登录项： list of apps with toggles (persist; on boot auto-open checked)
  • 共享： computer name edit
  • 传输或还原： 还原所有设置 (confirm flow), 抹掉所有内容 (confirm → clear keys → reload)
  • 外观： light/dark/auto + accent color choices
  • 辅助功能： reduce transparency, reduce motion, increase contrast, (text size?)
  • 控制中心： toggles for which modules show
  • Siri 与聚焦： spotlight keyboard shortcut info + toggles (search files/apps/settings)
  • 隐私与安全性： app permission list (fake), firewall toggle
  • 桌面与程序坞： size slider, magnify toggle+level, position, autohide
  • 显示器： brightness slider, night shift toggle+strength, resolution info
  • 屏幕保护程序： type select (off/clock/slides), delay select, preview button
  • 墙纸： wallpaper picker grid (thumbs)
  • 锁定屏幕： password enable/set/change, require immediately
  • 触控 ID 与密码： same password mgmt (share state) — the doc lists both; make 触控ID pane show "此 Mac 不支持触控 ID" + password shortcut
  • 用户与群组： avatar picker (few generated avatars), user name edit, guest
  • 键盘： key repeat sliders (cosmetic), 输入法
  • 鼠标： tracking speed (cosmetic), 自然滚动 toggle (affects? keep cosmetic)
  • 触控板： point & click cosmetic
  • 打印机与扫描仪： empty state + add button → "未找到打印机"
• Launchpad: fullscreen blur overlay, search, grid of all apps, click launch, Esc close, pagination? single page grid fine.
• Maps: canvas-drawn offline map (grid streets, parks, water, labels of Beijing landmarks), pan (drag), zoom (+/- and wheel), mode 标准/卫星 (satellite = darker green/brown palette), locate (centers), search local places (predefined list) with results + pin. If online tiles fail → we are the offline design. Doc says 联网地图失败时离线地图 — I'll just implement the designed offline map as primary (since static env), styled like Apple Maps-ish.
• App Store: tabs 发现/分类/搜索/更新； app cards (using icons: keynote, bear, typora, vscode, podcasts, news, github, tv...); 获取→安装中→打开 states; installed → adds .app to /Applications and Launchpad; persist.
• 活动监视器： process list (system procs + running apps) with CPU%/mem/energy jittering via interval; sortable columns; search; select → 结束 button; system procs → alert "无法结束系统关键进程"; app procs → close windows.
• 天气： Beijing default; current + hourly + 7-day; city add/remove via search (predefined city dataset w/ coordinates); use open-meteo API when online (no key needed) with cache; offline → cached or simulated data. open-meteo: https://api.open-meteo.com/v1/forecast?latitude=39.9&longitude=116.4&current=temperature_2m,weather_code&hourly=...&daily=... — free, CORS-enabled.
• 时钟： 4 tabs. 世界时钟 (add/remove cities, persist, live times), 闹钟 (add/edit/delete/toggle, fires notification when time matches), 秒表 (start/pause/lap/reset), 计时器 (set minutes, start/pause/reset, done notification + sound via WebAudio beep).
• 提醒事项： lists w/ colors (left), reminders (right): add/complete/delete/edit, due date; persist.
• 通讯录： list, search, detail card, add/edit/delete; preset Chinese contacts; actions: 发邮件 (opens Mail compose), FaceTime (opens FaceTime call).
• 便笺： colorful floating windows (separate from WM? Simpler: WM windows with app 'stickies' but each note its own window with color; autosave content; new/delete; color switcher; draggable via WM). Use WM windows with custom class.
• 邮件： 3-pane (mailboxes, message list, detail); preset mails; read/unread, star, delete, compose (to/subject/body → saves to 已发送 + fake auto-reply later), reply; persist.
• 信息： conversation list + bubbles; send → simulated reply after delay; timestamps; unread badges on dock? (badge maybe skip; unread dot in list); persist.
• FaceTime: contact grid; call screen: calling → connected (simulated video: animated gradient/canvas with avatar), controls (mute, video off, end); ended state → back.
• Preview covered above.

• Built-in pages rendered in-content (not iframe): macos://start, macos://weather, macos://news, macos://baike, macos://github.
• External URL: try iframe? Many sites block. Per decision: show designed offline page with "在新标签页打开" button (window.open). But some embeddable sites could work... keep deterministic: external → offline-style page: "无法连接到服务器/处于离线环境" styled like Safari error + open in new tab button + reload button.
• Search: uses searchEngine setting → builds bing/baidu URL → treated as external (offline page). Hmm, that's lame but consistent with "纯静态离线页回退" choice. To make search useful, I can implement search across built-in pages + suggest. Actually better: for bing/baidu search URLs, attempt iframe load with timeout → if fails show offline page. Cross-origin iframes to bing.com might load (bing allows framing? bing.com sends X-Frame-Options: SAMEORIGIN I believe; baidu too). Most likely blocked → offline page. I'll attempt with load/error detection via timer (can't detect XFO reliably; onload fires even on blocked? For blocked frames, Chrome fires load on error page... unreliable). Decision: deterministic offline page for external URLs (as user chose 纯静态离线页回退）, with "在新标签页打开" — honest and stable.

1. Spotlight found nothing for "memo" — because search matches app names in Chinese ("备忘录") and id 'notes'. "memo" doesn't match. That's expected behavior (id includes 'notes' not 'memo'). Fine — but let me test with '备忘' later.
2. Calendar icon in dock shows "17" — that's the calendar icon design, fine.
3. In the settings screenshot, the "自动" appearance preview shows a weird black/white — ok it's the 50/50 split, fine.
4. Lock screen: time shows 上午12:15 — fine. The wallpaper looks purple-pink (monterey w52) — good.
5. Desktop looks good; dock icons present; menubar Chinese labels working.
6. Finder breadcrumb shows "客人用户 Desktop" — good.
7. Window titlebars show centered icon+title — good.

1. music playing: no-audio — the audio element isn't found. My music app creates new Audio() — not attached to DOM, so document.querySelectorAll('audio') is empty. The playing check is wrong (test artifact), but let me verify the audio actually plays — check audio.paused via the app state instead. Also there are two 404s — which resources? Let me find them: probably audio file path with encodeURIComponent — assets/audio/Monkeys%20Spinning%20Monkeys.mp3 — the file exists as "Monkeys Spinning Monkeys.mp3" — with spaces, %20 should work. Let me check what 404'd. It might be favicon? index.html references assets/icons/finder.png as favicon — exists. Let me capture failed request URLs.

1. Trash flow (delete → trash-full icon → restore/empty)

1. quicktime readyState 0, error 4 (MEDIA_ERR_SRC_NOT_SUPPORTED or NETWORK) — the video failed to load. Why? Earlier the file downloaded fine and file said ISO Media MP4. Let me check the HTTP response for the video... The sandbox http.server should serve it. Error 4 = MEDIA_ERR_SRC_NOT_SUPPORTED. Maybe the mp4 is HEVC or the download was an HTML error page? big-buck-bunny.mp4 from test-videos.co.uk — let me verify all three files are real MP4 (ftyp header) and their codecs. ffprobe earlier showed h264 for all three? Earlier output was garbled but showed "h264" twice + once more. Let me re-probe each individually. Actually, in headless Chromium, H.264 may NOT be supported! Chromium open-source lacks proprietary codecs (H.264/AAC). That's why flower.mp4 (h264) fails. The audio MP3 played fine earlier?? MP3 is supported in Chromium. But H.264 video is NOT in headless open Chromium builds.

• Transcode videos to VP8/VP9 (WebM) — plays everywhere including headless Chromium. But Safari doesn't support VP9 in <video>
• Keep H.264 MP4 (best for real users) — error state shows in headless only.
• Provide BOTH: mp4 primary + webm fallback source. Use <source>

2. messages bubbles = 5 ✓ (me + auto reply). Next FATAL is at mail compose click .mail-col1 .fb-btn — mail window's compose button. Why timeout? Maybe the mail window didn't open because... dock icon mail exists. .mail-col1 .fb-btn — the compose button in mail sidebar. Hmm — possibly the mail window opened but the click on .dock-icon[data-app="mail"] opened... wait, bubbles test ran; then mail dock click; then .mail-col1 .fb-btn click timed out — perhaps the mail window was NOT topmost and its sidebar button is covered by the messages window. Both are 760-900px wide, cascaded. The mail compose button at top-left of mail sidebar might be covered by the messages window if messages window overlaps it and is on top? No — mail was clicked from dock after, so mail is on top. Unless mail didn't open...

15. Settings panes all render without errors (iterate all panes!)
16. Boot/poweroff/restart flows

1. In 13-zoomed: the calculator window didn't zoom (double-click hit the terminal window's titlebar instead? the terminal window looks normal-size too). Actually looking at 13-zoomed: windows all look normal size. The dblclick at (box.x+300, box.y+160)... box was the calculator window; after dragging by 200,120, then dblclick at box.x+300, box.y+160 → but the titlebar moved to box.y+120+20 = ... my test math was off (I dblclicked at box.y+160 which after drag is titlebar at y=box.y+140). y+160 is 20px into the window body (calc display), not the titlebar. So zoom didn't trigger — test artifact again, but let me verify zoom works via direct WM call in the final regression.
2. In 24-dark-desktop: mail dock badge shows "3" — nice. The notification badge works.
3. 16-dark: launchpad tooltip "启动台" visible at bottom — fine.

• Power off flow

1. settings panes rendered: 0 — SettingsApp.panes is empty at that point because panes are defined lazily in render() (definePanes called on first render). My test read panes before opening settings. Test artifact — but also worth making panes defined eagerly. Let me call definePanes at registration: SettingsApp.definePanes() right after registering. That also makes Spotlight settings search work before opening settings once. Good idea.
2. Activity monitor: clicked .am-row:has-text("地图") then .am-body .btn:has-text("结束进程") — the quit button timed out. The button text is "✕ 结束进程" — has-text("结束进程") should match. But the button is disabled until sel set. The click on am-row maps sets sel → quitBtn.disabled=false. Then clicking the button... timed out — maybe because the interval re-render every 2s replaces DOM and Playwright's click target detached → retry loop. render() re-creates the rows every 2 seconds; also clicking the row triggers render() immediately (rebuild). The quit button is in the toolbar (not rebuilt). Hmm, but the button is disabled at click start; Playwright waits for enabled — after row click it becomes enabled... then click should proceed. Timeout suggests the button never became enabled: maybe my row click missed because .am-row:has-text("地图") — the row contains 地图 in name; but render happens every 2s replacing rows mid-click → click action retries as element detached... but the log says "attempting click action" then timeout — the click itself was being retried on the quit button? Actually the FATAL is at line for quit button click. If sel didn't get set (row click detached), quitBtn stays disabled → timeout waiting for enabled.

const render = (soft) => {
  collect();
  // sort/filter rows list
  if (!soft) { full rebuild of DOM structure with current data }
  else { update values in existing cells; add/remove as needed }
};

1. reminder done: false — the check button click didn't mark done? .rem-row .rem-check — I clicked the first row's check. The first row might be an EXISTING reminder （体验 macOS 网页版）, not the new one. The new reminder "测试提醒事项" is appended at the end of open items. My test checked the first .rem-check which toggled a different item (marking '体验 macOS 网页版' done) — then queried the new item's done → false. Test artifact. But wait — actually clicking the FIRST rem-row's check toggled "体验 macOS 网页版" to done. So functionality works. Fix test to click the specific row.
2. FATAL at page.fill — which fill? After "new folder: true" comes the rename step: click .fb-item:has-text("测试文件夹") then keyboard Enter, then page.fill('.fi-rename', ...). The fill timed out — the rename input didn't appear. Why? Enter key on the content: my content keydown handler: if (e.key === 'Enter' && st.selection.size === 1) { st.startRename(...) }. The content has tabindex=0, but is it FOCUSED? After clicking the item, focus goes to... the item has tabindex=0 but click doesn't necessarily focus it; the keydown handler is on content. Clicking item → itemEl click handler runs (selection set), but keyboard focus may be on body or the clicked element (itemEl has tabindex=0 so it does get focus). The keydown bubbles from itemEl to content → handler runs. Hmm, but if focus is on the dialog-closed button... After the prompt dialog closed, focus might be on the previously focused button （新建文件夹 button in toolbar) — then clicking the item gives focus to itemEl (tabindex 0) → Enter should bubble to content. But Playwright's page.keyboard.press('Enter') sends to the focused element. If focus is still on the toolbar button, Enter clicks the button again (new folder dialog)! That would open another prompt dialog, blocking .fi-rename forever.

3. Also noticed earlier screenshots looked fine.

1. Resize handles (8-direction) — tested? Not yet explicitly. Test via mouse drag on se handle.
2. Window minimize via traffic light + dock restore.
3. Traffic light close.
4. Double-click desktop icon opens.
5. Launchpad search filter.
6. Alarm fires (set alarm 1 min ahead? tick checks every second via menubar clock — the alarm check happens on tickClock which runs every 1s. Set alarm to current minute+1 and wait ~65s — slow but doable; or directly call ClockApp.tick with mocked time? Simpler: set alarm to current time (this minute) → tick fires within a second... the check a.h*60+a.m === hm uses current minute — if I set alarm to NOW's h:m, next tick (within 1s) fires it. Test that.
7. Timer completion notification — set 2s timer... my timer min granularity is seconds via inputs; set 0min 3sec, start, wait 4s → notification.
8. Music seek/volume — visually fine.
9. 便笺 color change.
10. Terminal more commands (mkdir/rm/mv/cp errors).
11. Finder drag file to folder.
12. TextEdit dirty close confirm dialog.
13. 还原所有设置 flow (clears storage).
14. Boot progress animation visible.
15. Safari start page favorites.
16. Photos grid.
17. QuickTime error state (corrupt path? test via rename video? skip — error UI exists).
18. Offline wallpaper fallback (probe.onerror) — hard to test without breaking file; skip.
19. App Store 打开 installed app.
20. VS Code/bear etc. after install.

1. 31-weather: sidebar is too narrow ("北京" rows cramped), but functional. Weather window's left column shows city rows squeezed — width 220px ok but the search box overlaps? Looks acceptable. Actually the sidebar looks like ~90px wide — because .weather-left width 220... the screenshot shows it narrower relative to 780px window. Hmm, it's fine.
2. 30-settings: window title shows "Safari 浏览器 — 系统设置" — because the last pane iterated was safari. Good.
3. 34-fullscreen: notes fullscreen hides menubar ✓.
4. 35-menu: menu bar 文件 menu open with 新建备忘录/删除备忘录/关闭窗口 ✓. But notice the menu is quite high — fine.
5. 36-finder-list: list view works, context menu open ✓. But the Finder breadcrumb shows "客人用户 Desktop" — fine.
6. Calendar sticky window overlaps — fine.
7. 30-settings desktop icons: "Sample Fold er" wraps — name clamped to 2 lines, ok.

1. 开机进度条 2.3s — bootW check said "maybe" (width was already set to 100% by the time of read? I read at 600ms — transition starts after rAF; width style set to '100%' immediately with transition). Fine — visually verified in screenshot 01 earlier.
2. 锁屏→解锁动画 ✓ (tested click unlock).
3. 睡眠/注销 — implemented; sleep tested? Not directly. Quick test: call Sys.sleep() then wake. Let me add a mini check.
4. Ctrl+Space opens Spotlight ✓; Escape closes ✓.
5. 壁纸切换立即生效 ✓ (settings wallpaper pane tested via click? I tested rendering, not click. Quick check: click a wall-cell → desktop background changes).
6. 夜览/亮度 overlay — CC sliders tested earlier? I set values via evaluate. The CC panel sliders work (they're standard inputs). OK.
7. 多窗口轮换 via dock click — minor, implemented.
8. 日历今天高亮 ✓ visually.
9. Music 完成自动下一首 — implemented; not tested (would wait 20s). Trust code.
10. Safari 前进/后退 — implemented; quick check possible.

1. In 41-vscode, the finder sidebar "废纸篓" appears — ok.
2. The music app volume icon area at bottom right is empty-ish (music-vol empty div). Minor — could add volume slider. Let me add a volume slider to the music bar for completeness. Quick add.

1. Update todos.
2. Take a few "hero" screenshots for the final presentation (fresh profile, arranged windows).
3. Save version via website_version_manager (need to load the tool first).
4. Deliver.

1. Update todos (all build tasks complete).
2. Take hero screenshots for presentation.
3. Save version with website_version_manager (load the tool first).
4. Deliver with summary.

• Phase 1 (completed): Built a complete macOS web desktop simulator at /mnt/agents/output/macos-web/
• Phase 2 (just received, not started): User uploaded a second requirements doc asking to FIX the existing project with 5 phases, 15 groups of issues, tests/ directory with Playwright regression tests, ATTRIBUTIONS.md, and final delivery with modification list + root causes + test commands + results.

1. Reading the uploaded requirements document to confirm details
2. Reading all source code to build a behavior inventory
3. Setting up tests/ directory
4. Fixing issues group by group, running tests after each group

1. Check project exists
2. Read the second requirements doc (should be in /mnt/agents/upload)
3. Read source files
4. Build behavior inventory
5. Set up tests
6. Fix issues in phases

1. 先通读全部源码，建立当前行为清单
2. 搭建 tests/ 目录
3. 按阶段修复，每组修复后运行测试

• tests/ 目录，用全局 Playwright（绝对路径 require）
• run.js 作为测试运行器（自研轻量 runner：describe/it/断言/计数/退出码）
• helpers.js：启动 HTTP 服务器、unlock、collectErrors 等
• 分文件：01-boot.test.js ... 每组修复对应测试文件

• close(win) 无 closing 守卫：confirmClose 期间再次 close → 重复弹确认框；动画期间（150ms setTimeout）再次 close → doClose 可能执行两次。splice 前用 this.windows.indexOf(win)，如果已被移出，indexOf=-1 → splice(-1,1) 会删掉最后一个元素！这是真实的 bug：连续两次关闭计算器，第二次 close 在动画期间再次触发 doClose → windows.splice(-1,1) 误删备忘录窗口。
• 需要：closing 状态、Promise 化（resolve 'closed'|'cancelled'|'alreadyClosed'）、doClose 内重查 index>=0、onClose/timers/DOM 只执行一次。

• showLock/sleep/powerOff/restart 都有 WM.windows.slice().forEach(w => WM.close(w))：锁屏=关窗丢状态。
• powerOff 的 UI.confirm 在 unlocked=false 之前就弹（其实顺序：先 confirm，通过后才 unlocked=false）——但 confirm 期间如果窗口有脏文档，直接 close 会触发 confirmClose（文本编辑的存储确认）→ 两套对话框并发。且 powerOff 不等待 confirmClose 结果，直接显示关机画面。取消脏文档确认也不能中止关机。
• 锁屏不关闭浮层（菜单/CC/NC/Spotlight/Launchpad）。
• 锁屏层级：lockscreen z-index？看 base.css 后面部分。保存确认框 modal-mask z-index 6000（window.css:56 是 .menu-pop 6000？需要确认 modal-mask 的 z-index）。lockscreen 的 z-index 需要查。

• setActiveApp 在 wm:focus 时调用 app.menus(win)。Apps.open 顺序：WM.openWindow（内部 focus → emit wm:focus → setActiveApp → app.menus(win)，此时 win.appState 还是 undefined）→ 然后 app.render(win) 才创建 win.appState。
• menus(win) 返回的 menu 定义中，items 是函数（打开菜单时才求值），但 file/edit/view 数组本身在 menus() 调用时就已构造，数组元素里的 disabled: !st?.selection.size 等在 menus() 调用时刻就已固化。st = win?.appState 捕获的是 undefined。
• 所以首次打开 App 后，菜单里所有依赖 st 的项永远 disabled/无效（比如文本编辑首次打开时"文件→保存"action: () => st?.save()，st 是 undefined → 无反应）。但等等——items 是函数，每次展开菜单时调用，但函数闭包里的 file 数组是在 menus(win) 调用时构造的，disabled 和 action 的 st 都是那时的。所以必须：展开菜单时重新调用 app.menus(activeWin) 或让 st 动态求值。
• 修复方案：setActiveApp 存储的是"菜单工厂"，展开时重新生成。即在 item click 时调用 app.menus(WM.activeWin...) 重新获取 m.items。最小侵入：把 setActiveApp 中 for (const m of menus) 的 items 求值改为每次点击时重新调用 app.menus()。或者让 menus 存 label 列表 + 每次展开重新构建。我选：在 menubar item click 里重新调用 app.menus(currentWin) 找到对应 label 的 menu，求值其 items。这样每次展开都是最新的 disabled/checked/action。

• 当前：navigate(p, push=true)：push 时 history = history.slice(0, hi+1); history.push(st.path); hi++。也就是 history 保存的是"之前的路径"，当前路径不入列。back：p = history[hi--]; navigate(p, false)。forward：p = history[++hi]; navigate(p, false)。
  • 问题：Desktop→Documents→Downloads：history=[Desktop, Documents], hi=1, path=Downloads。back：p=history[1]=Documents, hi=0。back：p=history[0]=Desktop, hi=-1。forward：hi<len-1 → -1<1 → p=history[0]=Desktop！还是 Desktop（应该去 Documents）。因为 forward 用 ++hi 先自增。hi=-1 → ++hi=0 → history[0]=Desktop。错了，应该是 history[1]=Documents。
  • 还有 navigate(args.path) 在 render 末尾：render() 先执行，然后 st.navigate(args.path) push=true → history 写入初始路径（重复）。
  • 重写：history 保存完整访问路径含当前；index 指向当前。navigate：if push: history = history.slice(0, index+1); 如果 history[index] !== p 才 push；index++。back: index-- 用 history[index]；forward: index++。args.path：初始 history=[initialPath], index=0，不重复。

• itemEl click → renderList() 全量重建（innerHTML=''）。双击 = 两次 click + dblclick：第一次 click 重建 DOM 后，第二次点击落在新元素上……实际上 dblclick 事件还是会触发（因为是同一个元素位置？不一定——重建后新节点，浏览器对原节点的第二次点击可能因为节点被移除而丢失 dblclick）。任务书说"真实双击文件夹必须进入文件夹"——当前行为可能因为重建导致 dblclick 失效或打开两次。修复：选择变化只更新 class，不重建。用 updateSel() 只切换 .sel class。
• content click（空白）也 renderList() → 同样改 updateSel。
• contextmenu 里 selection 变化也 renderList → updateSel。
• 全选 keydown 也 renderList → updateSel。

• 无 tokenizer：split(/\s+/) → cd "~/Desktop/Sample Folder" 失败。
• rm：rest[0].replace(/^-[rf]$/,'') 逻辑混乱，rm -r 目录不区分、错误重复（try 里 FS.remove 抛错被 catch err()，同时自己的 err 也可能输出 → "每条错误只输出一次"）。
• mv：目标语义 hacky——FS.move(src, dstDir) 只能移动到目录；当前代码对"目标是文件路径"的处理是一团三元表达式，会重复调用 err 且可能 move 两次（FS.move(resolve(rest[0]) 被调用了两次！第一次在三元条件里 FS.exists(dst) 分支… 仔细看：
  JavaScript

  Sao chép

  FS.move(resolve(rest[0]), FS.isDir(dst) ? dst : FS.dirName(dst) && FS.exists(dst) ? (err('mv: 目标已存在'), dst) : (() => { const d = FS.dirName(dst); const np = FS.move(resolve(rest[0]), d); return FS.rename(np, FS.baseName(dst)), dst; })());

  如果 dst 不是目录且不存在：执行 IIFE → FS.move(src, d) + FS.rename。然后把结果 dst 作为 FS.move 的第二个参数再执行一次外层 FS.move！这是双重移动 bug。src 已经移到 dst 了，外层 FS.move(src, dst) 会抛"不存在"被 catch → 输出错误。实际效果是移动成功但输出一条错误。任务书说"修复 cp/mv 的目标文件名语义"。
• cp：FS.copy(s2, FS.isDir(d2) ? d2 : FS.dirName(d2)) — 目标是文件路径时只复制到目录，丢失目标文件名。需支持重命名语义。
• touch：已存在文件不更新 mtime。
• 需要 tokenizer：单双引号 + 反斜杠转义。

• DEFAULT_SETTINGS 无 notificationsEnabled、无 notifAllow per-app（有 notifAllow: {} 存在！但 Notify.send 不读它）。settings.js 的 notifications pane 用 S.notifGlobal 和 S['notif'+id]，与 DEFAULT_SETTINGS.notifAllow 不一致 → 开关无效。任务书要求 DEFAULT_SETTINGS 加 notificationsEnabled: true 和每 App 默认权限。
• banner markReadLater 6 秒自动已读 → 删除。
• focus 模式：当前 focus 时不显示 banner 但记录仍加入（已经"保存记录"），但未读语义：banner 消失自动已读 → 修复后未读保留。闹钟突破专注模式：加 allowedDuringFocus 选项，时钟闹钟通知传 breakthrough: true。
• renderDock 全量重建 → 局部更新 badge：写 Sys.updateDockBadges()，只更新 .dock-badge。
• 通知中心 Esc/点外关闭：当前 hideCenter 只加 nc-hidden；全局 Esc handler 没有处理 NC。点外关闭也没有。加上。

• emptied 自动注销 → 删。提供 unregisterMedia。音乐/QT/TV/播客 onClose 用 Sys.unregisterMedia。切 src 保留（video.innerHTML 换 source 会触发 emptied？换 innerHTML 后 load() → emptied 事件会 fire → 当前被注销 → 全局音量不再作用于它。修复后保留）。
• App 内音量滑块 vs 全局：任务书说"App 内音量滑块与全局音量保持一致，或明确实现独立音量模型，不能两套状态互相覆盖"。方案：统一为全局模型——App 内滑块直接读写 Sys.settings.volume（与控制中心一致），并监听全局变化同步自己。这样两套状态合一。音乐、QT 的 vol slider 改为控制 Sys.set volume；Sys.applyVolume 时 Bus.emit('volume:changed')，App 监听同步滑块位置。

• args.asset 但无 path → st.path=null → 进画廊分支 return → asset 丢失，且画廊里点击再开 {asset} 又进画廊 → 无限画廊。修复：args.asset 优先判断。壁纸缩略图点击 → 在同一窗口或新窗口打开大图（st.path=asset 渲染图片视图）。防无限画廊。

• util.js 加 localDateKey(date)。
• apps.js 日历 692, 718 行 toISOString().slice(0,10) → localDateKey。apps3.js 提醒事项 783 行 due 用 toISOString → localDateKey。
• 世界时钟 cityTZ 固定偏移 → IANA：cityTZ 改 { '北京': 'Asia/Shanghai', ... }，用 Intl.DateTimeFormat with timeZone。显示 UTC 偏移用新的 offset 计算。
• 设置时区：settings.js datetime pane 的时区 select 未接线（无 change handler、未保存）。DEFAULT_SETTINGS 加 timezone: 'Asia/Shanghai'（或 'local'）。任务书："系统设置的时区选择必须保存并影响系统内相关时钟"。影响哪些？菜单栏时钟、锁屏时钟、世界时钟本地行。方案：settings.timezone = 'local' 或 IANA 名；Sys.now() 辅助返回应用时区后的 Date？Date 对象无法直接换时区显示，但可以用 Intl.DateTimeFormat 格式化。菜单栏 fmtMenuClock(d, h24) 用本地方法。做法：提供 Sys.tzName()（返回 settings.timezone==='local' 时 undefined 即本地），fmtMenuClock/fmtTime 等支持传入 timeZone。简化：util 的时间函数加可选 tz 参数，Sys.tickClock/tickLockClock 传 settings.timezone。世界时钟城市行用各自 IANA。
• 注意 "亚洲/上海" 这种中文名要映射 IANA 'Asia/Shanghai'。

• render_sw/render_timer 每次 go(id) 时 box.innerHTML='' 重建 → 按钮文字、计次列表丢失（状态在 st.sw/st.timer 里但 UI 不恢复）。修复：render_sw 时根据 st.sw 状态恢复按钮文字和 laps 列表；render_timer 恢复 disp/按钮/进度。_swTick/_timerTick 在 tab 切换时被覆盖绑定到旧 disp —— 需改为读取当前 DOM 或存储元素引用。当前 this._swTick = (c,s) => { disp.textContent = ... } 在 render_sw 里闭包 disp；切走再切回，新 disp 创建，_swTick 重新绑定，OK。但 500ms interval 里 st.tab==='sw' && st.sw.running 才 tick。切走时 disp 不在 DOM 也无关紧要。关键：秒表 running 时切走切回，disp 应显示当前值、按钮"暂停"、lap 列表恢复。计时器 endAt 已用，但通知重复：_timerTick 在 left<=0 时 send 通知，每次 tick（500ms）都会进入 left<=0 分支？不——left<=0 后 running=false，之后 st.tab==='timer' && st.timer.running 为 false 不再 tick。但切回 timer 标签时 render_timer 重建，如果 left<=0 且 running=false，不会再发。但问题：timer running 时切到别的 tab，interval 里 st.tab==='timer' false → _timerTick 不执行 → 到点不通知！且切回时 left 可能早已 <=0，render_timer 后 _timerTick 触发一次 → 发通知（可能延迟）。还有重复通知风险：_timerTick 里 send 后 running=false；但如果用户在通知前切走，切回后补发一次——只有 500ms interval 绑定当前 tab。需要：计时结束检测不依赖当前 tab（interval 里 timer.running 就 tick 检测，UI 同步只在 tab 可见时）。防重复：st.timer.notified flag。
• 关闭窗口：win.timers 清理 interval → 计时器停止。任务书给了选择：移到全局 ClockService 或关闭前提示。选：确认提示——win.confirmClose：若 sw.running 或 timer.running，提示"计时器正在运行，关闭窗口将停止计时"。这样符合"否则关闭前明确提示"。

• 无法生效的标"模拟"：键盘（按键重复/延迟）、鼠标跟踪速度、触控板、打印机、触控 ID、网络详细信息、VPN、防火墙、共享、控制中心模块、蓝牙设备列表、Wi-Fi 已知网络连接按钮（需要保存状态：任务书"网络连接、蓝牙连接、时区、键盘/鼠标参数等至少要在模拟器内部保存状态并在重新打开后恢复"）。所以 Wi-Fi 已连接网络、蓝牙已连接设备、键盘/鼠标滑块值 → 存 settings 持久化，并标"模拟"。
• switch：toggle() 已有 role/aria-checked/tabindex/键盘。但 loginitems、dock、lockscreen 里的手写 sw 只有 click → 统一用 toggle 工厂或补齐 aria。settings.js 里有几处 el('div', {class:'switch'}) 手写（loginitems 168、dock 245、263、lockscreen 300）。补齐。
• 搜索点击进 pane：当前搜索只过滤 nav，点击 nav item 进 pane —— 已实现。验证即可。
• datetime 时区 select 接线保存。

• 四视口。检查 base.css:168 和 apps2.css:445 的 media 1100px。768×1024 需要折叠布局。
• openWindow 的 w = clamp(opts.w, opts.minW, u.w-20)：当 u.w-20 < opts.minW 时 clamp 返回 max(min,...)... clamp(v,a,b)=Math.min(b,Math.max(a,v))：b<u.w 时 a>b，Math.max(a,v)>=a>b，Math.min(b, ...)=b → w=b=u.w-20 < minW！但 resize 时 minW 又会撑大。任务书："窗口有效最小宽度必须取 min(configuredMin, viewportAvailable)"。修复：effectiveMinW = Math.min(minW, u.w-20)；openWindow 和 startResize 都用。clampAll 同理。
• Dock 小屏：dock icon 尺寸自动缩小。
• 菜单栏不覆盖：mb-right 缩窄时隐藏部分？用 CSS overflow。
• .di-name word-break:break-all → break-word（desktop.css:17、apps.css:37 fi-name）。任务书只点名桌面英文名，Finder 图标视图顺手也改 overflow-wrap:anywhere? 不，"不要在单词中间断行" → word-break: normal + overflow-wrap: break-word。中文仍可断行（CJK 默认允许）。

1. 写 tests/ 基建
2. 开始修 P0

• tests/run.js：Node 脚本，轻量 runner。用法：node tests/run.js [filter]。内部：
  • 启动 http.server（用 child_process spawn python3 -m http.server 8177 --directory 项目根）或 Node 自带 http 静态服务（避免 python 依赖，用 Node 写个静态文件服务器更简单可靠）。
  • 收集 tests/cases/*.test.js，每个导出 async (t) => {}，t 提供 page 工厂、断言。
  • 每个测试用新 browser context（清 localStorage）或复用？各测试独立性重要 → 每测试新 context。file:// 测试单独。
  • 断言计数、通过/失败汇总、非零退出码。
• tests/helpers.js：launch 浏览器、unlock(page)、openApp、collectConsoleErrors、resetStorage。

1. 写行为清单 tests/behavior-inventory.md
2. 写测试基建 tests/helpers.js + tests/run.js
3. 写基线测试（file:// 冷启动、HTTP 冷启动、控制台无异常）
4. 跑通基线

• Node 20，require 全局 playwright（绝对路径）
• 内置静态文件服务器（Node http + fs，不依赖 python）
• 扫描 cases/*.test.js，每个文件 export { name, run } 或 export default async fn
• 每个 case 独立 browser context（localStorage 隔离）
• 支持 filter 参数：node tests/run.js boot 只跑匹配的
• 输出 TAP 风格或简洁风格，最后汇总 passed/failed，exit code

• serveStatic(root, port) → { url, close }
• newBrowser() → browser
• newPage(t, { scheme }) → page + errors 收集
• bootToDesktop(page) — 等开机画面结束、解锁
• unlock(page)
• openApp(page, id) — 通过 evaluate Apps.open
• 一些断言助手

• page.goto(base)
• 等 #lockscreen 可见（开机 3.1s）
• 点击锁屏 → 等 #desktop 可见
• 解锁后 localStorage 在新 context 是空的 → seed 数据

module.exports = {
  name: 'boot-file',
  title: 'file:// 冷启动到锁屏并解锁',
  run: async (t) => { ... }
};

await page.waitForSelector('#lockscreen:not(.hidden)', { timeout: 8000 });
await page.click('#lockscreen');
await page.waitForSelector('#desktop:not(.hidden)', { timeout: 5000 });

1. file:// 冷启动到锁屏并解锁
2. HTTP 模式冷启动
3. 控制台无未捕获异常
