 ## 2026-06-20 桌面壳网络探测失败不可静默
 
 - 背景：Tauri 桌面壳 `network.status` 会把主站 TCP 可达性作为当前宿主网络状态；如果探测目标解析、DNS 或 TCP 连接失败后只折叠为 offline，H5 可以收到离线状态，但开发侧无法判断是配置、解析还是连接问题。
-- 决策：`resolve_desktop_network_status()` 必须通过 `resolve_desktop_network_reachability(...)` 得到可达性或失败原因；失败时记录 `desktop network reachability probe failed: ...`，再继续按离线 payload 返回。配置检查拒绝网络探测重新用 `.to_socket_addrs().ok()` 或 `connect_timeout(...).map(...).unwrap_or(false)` 静默吞错。
+- 决策：`resolve_desktop_network_status()` 必须通过 `resolve_desktop_network_reachability(...)` 得到可达性或失败原因；失败时只记录 `desktop network reachability probe failed` 固定标签，再继续按离线 payload 返回，不把解析目标、DNS 或 TCP 错误详情写入可分发桌面壳 stderr。配置检查拒绝网络探测重新用 `.to_socket_addrs().ok()` 或 `connect_timeout(...).map(...).unwrap_or(false)` 静默吞错，也拒绝重新拼接 `: {reason}`。
 - 影响范围：`apps/desktop-shell/src-tauri/src/shell/network.rs`、`apps/desktop-shell/scripts/check-config.mjs`。
 - 验证方式：`cargo test --manifest-path apps/desktop-shell/src-tauri/Cargo.toml shell::network`、`npm run desktop-shell:typecheck`、`npm run check:native-shells`、`npm run check:encoding`、`git diff --check`。
