根因:1.0.36 的 401 自愈触发 auth token 续期 → authProvider 状态变 → nodesProvider.build()
重跑 → Riverpod 先调上一轮 ref.onDispose(()=>_disposed=true),新 build 没复位 → _disposed
永久 true → setLivePing/_measure 开头的 if(_disposed)return 让 urltest 回写/延迟实测全部静默
→ 延迟冻在 —。修:① build 开头 _disposed=false 复位;② build 改 watch authProvider.select
((s)=>s.isLoggedIn),token 续期(accessToken 变但仍登录)不再重建 nodesProvider、不清延迟。
