 ## 设置
 
-**设置 → 通用 → 会话通知**：
+**插件 → 会话通知**（插件自己的介绍页里）：
 
-- 显示系统通知权限状态；
-- 未授权时点「允许通知」请求权限（浏览器要求必须由你手动点击才能弹权限框），授权后自动发一条测试通知；
-- 已授权时点「测试通知」随时验证；
-- 权限被系统层关闭时，按平台给出开启路径（Windows / macOS 的通知设置、Linux 桌面环境的通知设置）；
-- 三个开关分别控制**完成 / 授权 / 提问**三类提醒（默认全开；开关状态存在当前页面内存里，刷新回到默认——本插件不写配置文件）。
+- 三个开关分别控制**完成 / 授权 / 提问**三类提醒（默认全开），状态存在浏览器本地，重装插件不丢；
+- 系统通知权限状态；未授权时点「允许通知」请求权限（浏览器要求必须由你手动点击才能弹权限框），授权后自动发一条测试通知；权限被系统层关闭时按平台给出开启路径；
+- 「测试系统通知」直接走系统通知通道（窗口在前台也照发），专门用来验证系统通知本身是否可用；
+- 「运行状态」一段显示：窗口现在是前台还是后台（决定会走哪条通道）、观察器是否真的收到了会话状态、以及**最近一次投递走的通道与时间**。
+
+设置放在插件自己的页面里，而不是「设置 → 通用」：它是这个插件的配置，不是 DSH 的通用偏好。页面顶部是 DSH 自己渲染的插件标题与描述，所以这块配置不再重复标题，直接用一句「提醒是怎么送出去的」开头。
 
 ## 安装
 
-在 DSH 的 **插件 → 添加插件** 里填本目录的绝对路径即可（`plugin_manager` 也会做同样的安装）：
+### 1. 从 Git 仓库安装（推荐）
+
+在 DSH 的 **插件 → 添加插件** 的上方输入框里填：
+
+```text
+https://gitea.iwake.top/dsh-plugin/session-notify.git#v1.0.3
+```
+
+`#` 后面跟标签或提交，用来锁定版本；不写则取默认分支。跟随 1.x 最新版可以写 `#semver:^1.0.3`。仓库是公开的，不需要凭据，也不用改「安装源」。
+
+### 2. 本地路径安装
+
+把仓库克隆或下载到本机，在同一个输入框里填包目录的绝对路径，例如：
 
 ```text
 D:\DeepSeek Harness Plugins\dsh-session-notify
 ```
 
-安装后：
+### 装完之后
 
-- **浏览器半**随页面加载，刷新页面即生效；
-- **宿主半**为空壳（不改任何 DSH 状态），如需重启才生效，完全退出 DSH 再打开即可；
-- 本插件没有第三方依赖，不需要 pnpm 下载，也不需要构建步骤。
+- **浏览器半**随页面加载，**刷新页面**即生效；
+- **宿主半**是空壳（不改任何 DSH 状态、不注册服务与路由），只有它变化时才需要完全退出 DSH 再打开；
+- 本插件没有第三方依赖，不需要 pnpm 下载，也没有构建步骤。
 
 卸载：插件页里移除 `@dsh-plugin/session-notify`（它同时是 profile 的一个 bundle）。
 
 ## 平台说明与验证范围
 
 - **通道是跨平台统一的**：插件的提醒都通过页面（Electron 渲染进程）的 `Notification` 构造器发出，Windows 通知中心 / macOS 通知中心 / Linux 通知守护（libnotify、GNOME、KDE）都由系统把它转成原生通知；应用内轻弹窗是纯 DOM，与平台无关。
+- **前台/后台的判定不依赖单一信号**：每次都现读页面的可见性与文档焦点（任一为"不可见"就算后台），不靠"记住上次的 blur 事件"——桌面外壳里漏掉一次 blur 曾让插件误判为前台而吃掉提醒（v1.0.5 修）。
 - **宿主半拿不到系统通知**：DSH Desktop 的宿主进程是纯 Node 进程（不是 Electron 主进程），没有 Electron 的 `Notification` 可用，所以插件的所有提醒都在浏览器半产生——这也正是"三个平台一套代码"的原因。
-- **已验证**：Windows 上的安装、三个 slot 条目注册、以及 22 条投递规则（见下）的离线验证；设置行与轻弹窗的文案/交互按 DSH 自带的 toast 与 switch 组件对齐。
+- **已验证**：Windows 上的安装、三个 slot 条目注册、以及 28 项离线断言（接线 / 国际化 / 两种后台信号 / 系统通道被拒时的降级 / 配置页诊断 / 全部投递规则）。
 - **未验证**：macOS 与 Linux 上的实际弹窗效果本机无法测试。结构上它们与 Windows 共用同一条通道、同一份代码，只有"权限被系统关闭时显示的开启路径"是分平台的。
 - 提醒只在 DSH 进程运行、页面打开时产生：**DSH 完全退出期间结束的会话不会再补发通知**。

 依赖的都是稳定契约：
 
 - 浏览器半只依赖 **slot 的标准 props**（`useSessions`、`useSessionStatus`）读取会话状态，这是 DSH 官方给插件读会话数据的方式；不轮询、不自己订阅会话事件、不读别的插件的 DOM；
-- 只往两个官方 slot 注册：`settings.general.item`（设置行）与 `shell.overlay`（两个条目：轻弹窗层 + 无渲染的观察器，内容永远是 `null`）；
+- 只往两个官方 slot 注册：`plugins.bundle.config`（本插件在插件页里的配置，key 就是包名）与 `shell.overlay`（两个条目：轻弹窗层 + 无渲染的观察器，内容永远是 `null`）；
+- **配置放在插件页**：`plugins.bundle.config` 的 key 取包名（`@dsh-plugin/session-notify`），插件页就会渲染这块配置；官方 `dsh-experimental-voice-input-bundle` 用的就是这个口子。行级口子是 `plugins.row.config`，key 形如 `<包名>#<行 id>`，会在该行上多出一个「配置」入口；
 - **不要**把"无渲染"条目放进 `sidebar.panellist`：该 slot 的宿主会把**每个条目的 id 当成一个左侧面板按钮**（`entriesOfSlot('sidebar.panellist')` → 面板列表，按钮文字取 `options.label ?? options.id`，条目本身作为图标内联渲染），放进去会在左侧多出一行空面板并挤坏侧边栏。本插件第一版踩过这个坑，现已改挂到通用浮层；
+- **文案必须注册字典**：`ctx.locale.register('session-notify', { zh, en })`，否则 `locale.bind(ns)` 在查不到该命名空间时会把 key 原样返回——界面上就会显示成 `settings.title` 这样的原始键（本插件第二版踩过这个坑）。注册会在 locale 修订号上打点，已经渲染出来的部件会自动换上文案，不需要刷新；
+- **前台/后台要现读、不能只靠事件**：桌面外壳里 `blur` 可能不到，只记事件会让插件一直以为在前台而吃掉系统通知（本插件第三版踩过这个坑）。现在每次投递都读 `document.visibilityState` 与 `document.hasFocus()`；
+- 另外自带一份本地字典兜底：即使拿不到框架的 `t`、或 locale 服务没有保存注册，也会渲染中文/英文文案而不是原始键；
 - 样式只用主题 token，不 import 任何 `@deepseek-ai/dsh-client-*` 包（规范要求，也是渲染不被上游改动打断的前提）；
-- 宿主半不声明 `inject`、不注册服务、不注册路由。
+- 宿主半不声明 `inject`、不注册服务、不注册路由；三个开关存浏览器本地，不改 DSH 的配置文件。
 
 上游若改动 slot 名或 hook 名：注册会静默跳过而不是把页面弄坏，插件会退化成"不提醒"；这类情况请按上面的契约名核对。
