Description=Pangolin node agent (self-enrolls, manages local sing-box)
Documentation=https://github.com/wangjia/pangolin
After=network-online.target pangolin-server.service
# 软依赖:server 只是「想要先起」,不绑生死。agent 靠 gRPC 自重连,server 重启
# (如部署)绝不能把 agent 一起拖停——之前 Requires= 正是「agent 静默掉线」根因(#8)。
Wants=network-online.target pangolin-server.service
# 关闭重启频率上限,配合 Restart=always 保证永不放弃自愈(StartLimit* 属 [Unit])。

# The agent calls `systemctl restart sing-box` after rendering config;
# a polkit rule (49-pangolin-singbox.rules) lets the unprivileged pangolin
# user manage *only* sing-box.service.
