# /prototype/* is intentionally NOT disallowed: every legacy URL there now
# answers 301 to its live page, and a crawler must be able to FETCH the URL
# to see the redirect and drop it from the index.

# AI crawlers — explicitly allowed (search + answer citations).

# /article/* is crawlable and indexable (the blanket noindex was reverted in
# Sep 2026). Only Tier B articles carry "noindex, follow" on the page itself,
# and a crawler must be able to FETCH a page to read that tag — so nothing
# under /article/ is ever disallowed here. /AdminPanel, /Settings and
# /EmbedArticle are protected by authentication + noindex, not by robots.txt.

# Sitemaps — served by backend functions (the /sitemap.xml alias returns 404).
#   sitemapIndex → entry point: sitemapXml + sitemapNews + monthly article archive
#   sitemapXml   → landings, directories, company profiles, analytical notes
#   sitemapNews  → Tier A news from the last 30 days (news tags on the last 48h only)
#   rssFeed      → latest Tier A articles, RSS 2.0
