# Everything here is public, and every crawler is welcome to read it — the
# search engines, the assistants that fetch a page to answer a question with
# it, and the crawlers that read the web to train the next model. Being known
# is how a rider in a valley finds out an offline timetable exists at all.
#
# The groups below repeat `Allow: /` by name rather than leaving them to `*`,
# so nobody has to guess whether a particular bot was meant. A short summary
# written for language models is at https://spickme.ch/llms.txt.
#
# Nothing is disallowed, deliberately: a page that must stay out of an index
# says so itself with noindex (/connection/, short links), and a crawler
# refused here could never read that. docs/website.md, "What an AI reads here".

# One address, a sitemap index: the site's own pages, and the page per
# station and per busy pair of them that the planner's service writes from
# the current timetable (docs/station-pages.md, "How a search engine reads
# them"). Until 2026-10-24 the three were named here one by one, and a search
# console given the first saw sixty-three addresses of two hundred eighty
# thousand.
