sb-fixture:ai-search-bot-allow-reference:raw
In this site's generated robots.txt, GPTBot is disallowed from /tests/ai-modern-crawlers/blocked/gptbot while OAI-SearchBot carries no disallow for that path, so OpenAI's training crawler and its search-indexing crawler read different policies. A crawler honouring per-agent rules applies the disallow to GPTBot only and leaves OAI-SearchBot access intact.
