# verify_apps.sh — R3 Pro II 应用加载器真机全链路验证编排
#
# 用法:
#   ./verify_apps.sh stab           稳定性检查(60s 单实例无 recovery_all)
#   ./verify_apps.sh nav QOBUZ      触摸注入导航流媒体页->Qobuz(应用列表页)
#   ./verify_apps.sh shot <name>    fb0 截图存 device_test/<name>.png(+ascii)
#   ./verify_apps.sh tap <x> <y>    goodix 触摸注入(坐标按设备 abs 缩放)
#   ./verify_apps.sh scen <n>       布置 TF 卡场景 n (0..5, 见下)
#   ./verify_apps.sh exitapp        让 hello 退出(注入任意键)
#   ./verify_apps.sh wdtap          点击看门狗虚拟返回键(20,20)
#   ./verify_apps.sh loop <n>       重复 n 次 列表->启动->返回键退出
#   ./verify_apps.sh devinfo        输入设备 abs 范围等调试信息
#
# 场景:
#   scen 0  正常: MeowAPPs/hello/(hello + app.json 有效)
#   scen 1  无卡: umount sd_0 (测试后必须 scen 0 恢复)
#   scen 2  无 MeowAPPs 目录
#   scen 3  MeowAPPs 空目录
#   scen 4  坏 app.json(缺 exec 字段, 应跳过)
#   scen 5  exec 不存在(点击应提示无法启动)
