Extract and preserve WeChat public-account articles from mp.weixin.qq.com links into Markdown for AI research and evidence workflows. Use when Codex needs to read a Chinese WeChat/微信公众号 article, when Jina/ReadGZH returns captcha, 401/402/429/503, "环境异常", or when OpenCLI Browser Bridge should be used to download公众号文章正文, save evidence paths, and continue upstream research without bypassing verification.
