### AI overview

A field note explains how a Cloudflare AI-bot blocking setting returned 403 responses to all AI agents even though the site's robots.txt allowed AI search and blocked training crawlers. It distinguishes training crawlers, search indexers, and user-triggered fetchers, and recommends auditing enforcement at the firewall layer.
