 # CHANGELOG
 
+## [0.6.4] - 2026-04-28
+
+### 修复
+- **[node-gfw-check]**: 修复墙检测任务卡在 `pending/checking` 后会长期占用 active 状态的问题；超过 5 分钟未被节点端领取或未上报的任务会标记为检测失败，管理端区分展示“等待节点领取”和“检测中”。同时修正 mi-node 的 ping 成功判定，避免正常可达但平均延迟解析不到时被误判为超时 — by yinjianm
+  - 类型: 快速修改（无方案包）
+  - 文件: app/Services/ServerGfwCheckService.php, app/Console/Commands/SyncServerGfwChecks.php, admin-frontend/src/utils/nodes.ts, admin-frontend/src/views/nodes/NodesView.vue, E:/code/go/mi-node/internal/gfwcheck/gfwcheck.go

 - 管理端 `POST server/manage/checkGfw` 接收 `{ ids: number[] }`，响应中区分 `started` 与 `skipped`

 - 节点端 `GET server/gfw/task` 只向父节点返回待执行任务；节点端 `POST server/gfw/report` 必须校验 `check_id` 归属当前节点
 - `v2_server.gfw_check_enabled` 控制节点是否参与自动墙检测与墙状态自动显隐；父节点开启时会自动创建检测任务，子节点不独立检测但可单独关闭随父节点自动隐藏 / 恢复
 - `blocked` 结果会自动隐藏仍开启墙检测托管且当前显示中的父节点及其子节点，并设置 `gfw_auto_hidden=1`

 - `sync:server-auto-online` 会把最新墙状态 `blocked` 和未恢复的 `gfw_auto_hidden` 作为显示否决条件，防止自动上线重新发布疑似被墙节点
 - 当前检测方向只做节点服务器主动 ping 国内三网目标；后续墙内探测 IP 可在同一任务模型中扩展
 - 参考脚本中的 Telegram 通知、chat_id、bot token 和自动安装依赖逻辑不得进入项目实现
-- mi-node 使用 Go 原生 runner 调用系统 `ping`，按三网目标并发检测并结构化上报 `summary / operator_summary / raw_result`
+- mi-node 使用 Go 原生 runner 调用系统 `ping`，按三网目标并发检测并结构化上报 `summary / operator_summary / raw_result`；ping 命令成功即视为目标可达，平均延迟解析失败不再把正常可达误判为超时
 - Docker runtime 镜像需要提供 `ping`，当前通过 Alpine `iputils` 满足
