The host sits behind a Cloudflare interactive bot challenge that answers HTML paths with a 403 "Just a moment..." interstitial, so 403 below means "challenged, not served" rather than a true authorization failure. Notably /robots.txt (200) explicitly Allow:s GPTBot, ChatGPT-User, PerplexityBot, ClaudeBot, Claude-Web and Google-Extended, which the WAF configuration then contradicts by challenging those same agents. hosts: - host: https://koo.bz documents: - path: /.well-known/security.txt status: 404 - path: /.well-known/openid-configuration status: 404 - path: /.well-known/oauth-authorization-server status: 404 - path: /.well-known/api-catalog status: 404 - path: /.well-known/ai-plugin.json status: 404 x-shape-fix: converted: '2026-08-20' from: documents note: Rewritten into hosts[] -> documents[], the only shape well_known_docs() in score.rb reads.
