问题

CLI 每次运行都会打印 Node.js 的 SQLite experimental warning：

(node:26703) ExperimentalWarning: SQLite is an experimental feature and might change at any time
(Use node --trace-warnings ... to show where the warning was created)

这是 node:sqlite 模块的标准警告，但对用户来说是视觉噪音，没有实际价值。

方案

在 CLI 入口（或 daemon/worker 启动时）通过 process.removeAllListeners(warning) 或 --no-warnings flag 过滤掉 ExperimentalWarning 类型的警告。

推荐做法：在入口处加一个 warning filter，只屏蔽 ExperimentalWarning，保留其他警告：

const originalEmit = process.emit;
process.emit = function (event, ...args) {
  if (event === warning && args[0]?.name === ExperimentalWarning) return false;
  return originalEmit.apply(this, [event, ...args]);
};

或者在 spawn worker 时加 NODE_OPTIONS=--no-warnings。
