# The two indexes that gate the LARGEST AI surfaces, named so they get the same
# protection as the small ones. AI Overviews and AI Mode are served from the
# Googlebot index — not from Google-Extended, which is grounding and training
# only. Copilot is served from the bingbot index. Without these groups a future
# Disallow in the `*` group above would drop this site out of Google AI
# Overviews, Google AI Mode and Copilot while leaving ChatGPT and Claude
# untouched — the exact accident the comment at the top exists to prevent.
