# AI crawler policy (decided 17 October 2026): all three AI categories below are deliberately
# allowed: AI search and answer engines, user-triggered AI fetchers, and AI model training
# crawlers. The groups are listed separately so each can be changed on its own. Review this
# file quarterly against each vendor's crawler documentation, as user agents and their
# purposes change.
