 ## 2026-06-18 原生壳身份与 capability 作用域门禁
 
 - 背景：Expo 移动壳和 Tauri 桌面壳已经具备首批真实 HostBridge 能力，但如果包身份、桥版本、Android 默认权限、Tauri 窗口列表或 capability 文件在后续迭代中漂移，会把 H5 主站装进更宽的宿主权限面。
-- 决策：移动壳配置门禁固定 Expo `name`、`slug`、`userInterfaceStyle`、`assetBundlePatterns`、`extra.genarrativeHostBridgeVersion`，并要求 Android 默认 `permissions` 为空，只通过 `blockedPermissions` 阻断当前不需要的高风险权限；`apps/mobile-shell/scripts/check-config.mjs` 检查源 `app.json`，`apps/mobile-shell/scripts/check-expo-config.mjs` 检查 Expo CLI 最终解析出的 public config，防止 config plugin 或解析阶段引入身份、资源或权限漂移。新增权限必须先有真实宿主能力、系统权限说明和 H5 fallback。桌面壳配置门禁固定唯一 `label=main` 主窗口，`src-tauri/capabilities/` 只能存在 `main.json`，且该 capability 只能绑定 `windows=["main"]`、`permissions=["allow-host-bridge-request"]`，继续只暴露 `host_bridge_request` 一个受控入口。
+- 决策：移动壳配置门禁固定 Expo `name`、`slug`、`userInterfaceStyle`、`assetBundlePatterns`、`extra.genarrativeHostBridgeVersion`；Android 源 `app.json.permissions` 只能手写 `RECORD_AUDIO` 供同源 H5 实时声音玩法使用，`CAMERA` 必须只由真实 `expo-camera` / `expo-image-picker` 插件为扫码和拍摄能力生成到最终 Expo public config，仍通过 `blockedPermissions` 阻断当前不需要的高风险权限；`apps/mobile-shell/scripts/check-config.mjs` 检查源 `app.json`，`apps/mobile-shell/scripts/check-expo-config.mjs` 检查 Expo CLI 最终解析出的 public config，防止 config plugin 或解析阶段引入身份、资源或权限漂移。新增权限必须先有真实宿主能力、系统权限说明和 H5 fallback。桌面壳配置门禁固定唯一 `label=main` 主窗口，`src-tauri/capabilities/` 只能存在 `main.json`，且该 capability 只能绑定 `windows=["main"]`、`permissions=["allow-host-bridge-request"]`，继续只暴露 `host_bridge_request` 一个受控入口。
 - 影响范围：`apps/mobile-shell/scripts/check-config.mjs`、`apps/mobile-shell/scripts/check-expo-config.mjs`、`apps/desktop-shell/scripts/check-config.mjs`、Expo / Tauri HostBridge 方案文档。
 - 验证方式：`npm run check:native-shells`、`npm run typecheck`、`npm run check:encoding`、`git diff --check`。
