robots.txt check: fetches the origin's /robots.txt server-side and reports whether a given URL path is allowed or blocked for a user agent, with the matched rule, the robots URL, the HTTP status, a timestamp and a tamper-evident receipt. Query parameters: url (required), user_agent (optional, defaults to *). Only robots.txt is fetched; no crawling. Pair with GET /api/v1/link-map or /api/v1/sitemap to plan an allowed fetch.
