# Content Signals
#
# A 2025 proposal for stating content policy in one line a crawler
# can parse, rather than inferring it from a list of user-agent
# groups. Everything is open here, which is what the Allow: /
# directives above already say: Google-Extended and CCBot are both
# allowed, and this site's argument is that being readable by AI is
# the point. A signal that contradicted those rules would be worse
# than no signal at all.
#
# Adoption is early and no major engine has committed to honouring
# it, so our own scanner weights it 1 point out of 16 in the
# AI Crawler Access dimension.
