# Line9 robots.txt — public marketing + product surfaces are crawlable. # Published user diagrams at /d/* stay crawlable so crawlers can see their # noindex (JUM-492); they are excluded from the sitemap instead. # /sign-in is crawlable under * so search engines can read the page. Named AI # groups still disallow it, because a form page gives them nothing. Other # private surfaces stay disallowed for every user-agent group (named AI groups # do not inherit the * Disallows). # --- AI / generative-engine crawlers (explicit allow for public content) --- # "No blocks" means no blanket ban of public pages — private Disallows still apply.
