 - 先通过 `gotoStable`、`waitWorkbenchReady` 或等价导航进入目标 origin，再用 `fetchJson` 读同源 API；不要在 `about:blank` 上请求 `/v1/...`。
 - Workbench 有 SSE/长轮询时不要用 `networkidle` 判断通过；用明确 DOM/API 条件，如 final URL、route conversationId、active tab、message card、trace row 或 workspace `selectedConversationId`。
 - Playwright `page.evaluate` 只能传一个可序列化参数；多个值包成对象，或用 `safeEvaluate(fn, { a, b })`。
