- 问题: 30-collaplex-eq.conf 的 node.target 是安装时探测一次写死的。开机时设备若还没枚举 (USB 耳机晚到很常见: 09-24 实测开机 08:57、耳机 09:19:43 才出现; 09-23 是 21:01 → 21:03), 建链时目标不存在 → 末段连到别处或干脆不连, 设备出现后不会自己改回来 → 听感"双重混响", 只能 stop + start - 新增 web/output_route.py: 设备清单(pw-dump) + 选择落盘(output.json) + 守护线程(每 3 秒核对 collaplex_eq_out 只连选中设备, 不对就拆错的、按声道补对的) → 设备一出现自动挂上 - web/server.py: GET /api/devices, POST /api/device(落盘 + 立刻挂载), 快照带 output 段, main() 起守护线程 - web/index.html: 「输出设备」卡片(下拉 + 应用 + 状态 + 守护备注; 设备表变化才重建选项, 免得 60 Hz 重建打断点击) - 脚本/安装.sh: 优先用记住的设备(不在位也照样按它建链), 不再"猜第一个 digital" - 实测: 面板真点应用切走再切回 ✓ / 连错 2 秒自动纠回 ✓ / 全拆 3 秒自动挂回 ✓ / start 自检 打印 [在位] ✓ / 面板像素验收 ✓; pyright strict 0 errors 0 warnings - 坑: pw-dump 的 Link 键名是 output-port-id / input-port-id(写 output-port 一条连线都读不到); 面板服务 enable --now 不会重启已在运行的实例(改 web/*.py 必须 restart)
