> - Windows cmd-window storm + daemon spawn throttle (#592 宿主紧急 rant 2026-08-09T13:16:36（最高优先级，Windows v0.2.15 宿主实测 cmd 弹窗风暴被迫重启 + daemon 启动失败 GUI/scheduler 无法连接）：根因①代码库零处 CREATE_NO_WINDOW——每个 subprocess（git/gh/bash 工具/scheduler/daemon spawn）在 Windows 都弹控制台；②GUI 重连循环每 ~5s 重拉 emrgd.cmd 且每次与前一 daemon 启动竞争（G43 stale-port unlink 删掉健康 daemon 的 port 文件 → scheduler 连不上 93 次）；③scheduler 无连接失败退避。修复=新增 `emrg/_win.py` `win32_no_window_kwargs()`（win32 返回 {creationflags: CREATE_NO_WINDOW}，其余平台 {}）splat 进全部 34 处 subprocess 调用点；daemon spawn 加退避/节流；G43 不删活 daemon 的 port 文件（#593 深化）；+测试覆盖) ✅
> - Port-file self-heal + G43 PID guard (#593 外部贡献 pm25coder/#592 根因深化：daemon 侧新增 `_port_keepalive_loop` 每 60s 检查 `emrgd.port` 缺失即用当前 listener 端口重新 `_assert_port_file`（提取自 startup 的原子写逻辑，外部 G43 unlink 自愈），shutdown 干净 cancel；GUI `daemon_client.js` 新增 `_daemonProcessAlive()`（读 `~/.emrg/emrgd.pid` + `process.kill(pid,0)` 探测，EPERM=存活（Windows 权限），ESRCH/ENOENT=死亡），G43 捕获路径先查 pid——daemon 活着【绝不删 port 文件】（瞬时失败→退避重试 + 抛 "daemon unreachable (pid alive)"），只有真死才 unlink+重拉；+57 pytest（_assert_port_file 提取/keepalive 重断言/shutdown cancel）、+49 GUI 测试（_daemonProcessAlive 正反两态）641→650 / 96→101，README/Agent 计数同步) ✅
> - TUI daemon spawn throttle (#594 #592 客户端侧总闸补完：`daemon_manager.py` 模块级 `_MAX_SPAWN_ATTEMPTS=3` + `_spawn_attempts` 计数——`start_daemon()` 超限抛 `RuntimeError("daemon failed to start after N attempts — please run 'emrg server' manually...")`（TUI app.py `_reconnect` 循环每 1s 调 ensure_connected → 无限 spawn 即 Windows 弹窗风暴源），`ensure_connected` 成功连接后计数归零（连接生命周期语义，与 GUI daemon_client.js auth_ok 归零一致）；`app.py _reconnect` 捕获节流错误一次（`_throttle_warned`）→ 一次性系统消息 + status 提示 "daemon down — run 'emrg server'"；+56 pytest（3 次 spawn 无第 4 次 await_count 断言 / 成功连接归零 / autouse fixture 防跨测试泄漏）→ 合并后 652 全绿) ✅
