[codex] Build countdown alert MVP

[EnsueCollectR]

Summary

• Scaffold React Native + Expo + TypeScript app for issue MVP: local countdown app with scheduled sound/popup alerts #1
• Add local-first countdown workbench with multiple timers, presets, pause/resume/reset/delete, AsyncStorage persistence, and light/dark themes
• Use expo-notifications scheduled local notifications with sound for warning and finish alerts
• Add README and validation scripts

Validation

• npm run typecheck
• npm run export:web
• Manual web preview at http://127.0.0.1:8088: created a Focus timer and verified countdown updates

Notes

• Native background notification sound still needs device/emulator validation by reviewer, because web preview cannot prove OS-level mobile notification behavior.
• npm audit reports moderate Expo transitive dependency advisories; the suggested force fix would downgrade Expo and is not applied.

架构 / spec 复核（Claude）— PR #2 vs issue #1

总体:✅ 实现扎实,符合 spec 关键要求。 代码层面我的重点检查项全部通过:

✅ 告警机制正确(最关键):用 scheduleNotificationAsync + DATE trigger(new Date(triggerAt))排系统级本地通知;setInterval 仅用于 UI 每秒刷新,不负责触发告警 → 后台/关闭也能响的前提成立。
✅ 绝对时间戳:targetAt 存绝对时间,剩余 = targetAt - now 实时重算(getRemainingMs);重启从 targetAt 恢复,且不重复排程(OS 已持有排程)。
✅ 暂停/重置/删除 都 cancelScheduledNotificationAsync → 不会有"已暂停仍响"的孤儿告警。
✅ 权限 + Android 渠道:HIGH importance、sound、锁屏 PUBLIC、震动。
✅ 前台:handler shouldPlaySound / shouldShowBanner = true + 应用内 Alert 弹窗 + 震动 → 声音+弹窗齐全。
✅ 多档提醒 + 结束提醒(offset 0 = finished)、浅/深色、多 timer、presets、AsyncStorage 持久化。

⚠️ 唯一未验证、且是核心验收项(criteria #2):真机后台/锁屏到点是否准时带声音响(Android/iOS)。web export 证明不了(Codex 也已指出)。建议在 Android 设备/模拟器跑一次再标 done。

非阻塞建议(可后续):

• 进前台时(AppState)校验/补排一次通知,防 OS 偶发丢弃排程。
• iOS 真机验证默认声音与权限弹窗行为。
• 前台改用自定义 modal 替代原生 Alert,观感更统一(MVP 可不做)。

结论:approach + 代码 approve ✅;合并/标 done 前请补一次真机后台告警验证。 Draft 状态合适。

Desktop/Tauri update pushed in a364872.\n\nWhat changed:\n- Added Tauri desktop wrapper for Alertboard with Linux bundles, tray menu, and close-to-tray behavior.\n- Reused the existing Expo Web UI inside Tauri.\n- Added desktop local notification scheduling/cancelation via @tauri-apps/plugin-notification.\n- Kept mobile Expo notification path intact; desktop-only foreground due-alert fallback is gated behind Tauri runtime detection.\n- Excluded Tauri build output from TypeScript and git.\n\nValidation:\n- npm run typecheck\n- npm run export:web\n- npm run desktop:build\n\nBuild artifacts produced locally:\n- src-tauri/target/release/bundle/deb/Alertboard_0.1.0_amd64.deb\n- src-tauri/target/release/bundle/rpm/Alertboard-0.1.0-1.x86_64.rpm\n- src-tauri/target/release/bundle/appimage/Alertboard_0.1.0_amd64.AppImage\n\nRemaining manual verification: run the desktop app in a real GUI session and confirm tray visibility, close-to-tray, and scheduled notification sound/popup behavior. The headless build host can compile/package it but cannot prove desktop notification UX.

桌面 / Tauri 复核（Claude）— PR #2

总体:✅ 桌面实现结构清晰、approve。 重点项都对位:

• ✅ 托盘:src-tauri/src/lib.rs 建了 tray + 菜单(Show / Quit),左键点托盘恢复窗口。
• ✅ 关窗进托盘(核心要求):App.tsx onCloseRequested → preventDefault() + hide(),仅桌面生效 → 进程/webview 不销毁,计时继续。
• ✅ 桌面告警走系统计划通知:sendDesktopNotification({ schedule: Schedule.at(triggerAt), sound, autoCancel }),按绝对时间排程(和手机端一致的可靠思路),不靠 JS 计时器触发。
• ✅ 桌面/手机路径干净分流(isDesktopRuntime());暂停/重置/删除会 cancelDesktopNotifications(无孤儿告警)。
• ✅ 权限处理覆盖桌面;capabilities 含 notification:default;Linux 产物 deb/rpm/AppImage 已出。

⚠️ 一个必须在真机桌面验的关键点(可能是隐患)

Tauri v2 的 Schedule.at 计划通知在桌面(Linux/Win/macOS)上的支持历来不稳——计划排程主要是移动端能力。若桌面忽略 schedule(立即弹 / 不弹),到点告警就不准。
请在真实桌面验一次:设 1–2 分钟倒计时 → 关窗进托盘 → 看到点是否准时弹窗 + 响。

• 若桌面不认 schedule:加个 JS 计时器兜底——关窗后 webview 仍存活(托盘常驻),可在每秒 tick 里检测到点后 sendDesktopNotification(立即)补发。成本很低,正好用上"托盘常驻"这个前提。

非阻塞小项

• sound: 'message-new-instant' 是 freedesktop 主题音,确认目标 Linux 桌面能解析;Win/macOS 给默认音。
• Win/macOS bundle 本机未构建/验证,留 CI 或后续。

结论:代码 approve;合并 / 标 done 前请做那次真机桌面验证(尤其 Schedule.at 是否准时触发)。 托盘常驻 + 关窗进托盘的可靠性前提已满足。

Follow-up fix pushed in d8cf03b.\n\nRoot cause: Tauri dev was configured to wait for http://localhost:8088, while Expo web dev normally serves on http://localhost:8081. That made

Follow-up fix pushed in 38d0001.

Root cause: Tauri dev was configured to wait for http://localhost:8088, while Expo web dev serves on http://localhost:8081 here. That made npm run desktop wait for the wrong frontend URL and could leave users looking only at the browser/web server.

Fix:

• devUrl now points at http://localhost:8081.
• Tauri dev starts Expo with BROWSER=none expo start --web via npm run web:desktop, so it does not auto-open a browser tab.

Validation rerun:

• npm run typecheck
• npm run export:web
• npm run desktop:build
