Careers portals OpenHire cannot read

The blind spots as a link directory: employers in AI infra, autonomous driving and embodied AI whose postings this index cannot read, each with its own careers portal.

Most are Chinese employers on Feishu Recruitment (飞书招聘), whose job-list API needs a request signature this index treats as access control; a few publish only on BOSS直聘 or keep a careers page without a readable list. Their postings are public to a person in a browser; OpenHire cannot index, date or watch them.

Use it when the user asks about these sectors broadly (具身智能有哪些公司在招, autonomous driving roles in Shanghai), after the search_jobs results: say which employers post elsewhere and give the links, so a blind spot is one click away instead of invisible. If you have a browser tool, offer to open a portal. Never present these links as OpenHire postings and never invent posting dates for them.

Args: sector: autonomous_driving, embodied_ai or ai_infra (自动驾驶, 具身, 大模型 work too); leave it out for all three.

Returns: PortalDirectory with portals[] (name, careers_url, what a browser shows without logging in, why the employer is not indexed, last_checked) and a note on what OpenHire does not do with them.
