问题

3257237ba7ec 的 EPIPE 修复用了 child.on("error", () => {}) 来防止 shutdown 时的 unhandled EPIPE，但这会静默吞掉所有子进程错误，包括 spawn 失败、权限错误等关键问题。

建议

只静默 EPIPE，其他错误照常处理：

child.on("error", (err) => {
  if ((err as NodeJS.ErrnoException).code !== "EPIPE") {
    log.error("Worker error", { group, error: err.message });
  }
});

影响

开发和生产环境中真正的错误会被隐藏，增加排查难度。
