How this is observed: CipherCue reads the public robots.txt each organisation publishes and records the disallow rules it declares per named user-agent. A site is recorded as blocking Claude-SearchBot when its robots.txt disallows the site root for that agent (or the * catch-all). robots.txt is a stated preference the crawler chooses whether to honour; this records what the site declares, not crawler behaviour. See the AI-crawler methodology.
