    Corrected after the automated probe: lang.ai serves
    "Strict-Transport-Security: max-age=63072000; includeSubDomains; preload" on its 301
    redirect to https://capacity.com/lang/, which the probe followed before reading
    headers.

    Not a real host. "company" is the documented placeholder for a customer's own Lang.ai
    instance subdomain in the base URL https://{company}.lang.ai/api/v1, so this row is
    expected to fail verification and is retained only to record that the probe ran.
