#!/data/data/com.termux/files/usr/bin/bash
# keepalive.sh — Pixel 微信自动回复保活脚本
#
# 守护以下进程，挂了就重启：
# 1. termux wake-lock — 防 Doze 冻结 Termux:API（通知监听依赖它）
# 2. HermesAccessibilityService — A11y 易被系统/更新关掉，发现 enabled_accessibility_services=null 就重启
# 3. hermes-agent gateway — :8642，LLM 网关
# 4. auto-reply.js — 微信回复主程序
#
# 用法（在 Termux 用户 shell 里运行；不要在 root shell 起，wake-lock 拿不住 Termux 进程）：
# nohup bash ~/hermes-wechat/keepalive.sh > ~/hermes-wechat/keepalive.log 2>&1 &
#
# 前置条件（一次性设置）：
# 1. Android 设置 → 应用 → Termux / Termux:API / 微信 → 电池优化 → 不优化
# 2. Termux:API 已安装，并已授予通知访问权限
# 3. lsposed-wechat-sendmsg APK 已安装（含 HermesAccessibilityService）
# 4. ~/hermes-wechat/start-ar.sh 存在并已设置 MY_WXID / MY_NICKNAME
