dsh-restart-systemd

English summary. A DeepSeek Harness WebUI restart button (systemd edition). Adds a sidebar‑footer restart trigger next to the remote‑web‑ui phone icon plus a /restart command. Clicking schedules systemctl --user restart dsh-web (~3s later, so the browser gets its 202 first), dups are refused (409), non‑loopback callers are refused (403), a flag‑file + residual‑window design prevents restart loops, and after the service comes back up the browser auto‑reconnects without a manual refresh (ConnectionController exponential backoff 500ms→10s) while interrupted agent turns are auto‑resumed. Platform: WSL/Linux → systemctl --user (primary, tested); Windows → detached helper branch is present but unused on WSL.

设计总览

双面插件（与 dsh-client-ui-aionui-panel 同构）：

半边	entry（exports）	运行环境	职责
host	"." → lib/index.js	node（宿主导进）	/api/restart-dsh 路由、/restart 命令、flag/resume 状态、restart-recover
client	"./client" → lib/client.js	浏览器（WebUI）	侧边栏 footer 重启按钮 + 二次确认 + 状态反馈

src/
  index.ts               # host apply()：串联路由 + 命令 + boot 消费/resume
  host/gate.ts           # loopback fence（照抄 dsh-aionui-panel 的 gate）
  host/restart.ts        # 调度 + 延迟 spawn + 平台分支 + flag/单飞锁
  host/recover.ts        # agent/created -> lastTurnInterrupted -> followup continue
  client/index.ts        # client apply()：locale + sidebar.footer.action 注入
  client/RestartButton.tsx   # 按钮 + 确认对话框（内联样式，无需 CSS bundle）
  client/api.ts          # POST 助手 + 重连探活

内部依赖：官方 socket sidebar.footer.action（list/root additive，remote-web-ui 电话图标同座）+ 备选 conversation.session.header.utilities。
