Not a crawler. A robots.txt token that tells Google whether pages Googlebot already fetched may be used to train and ground Gemini. You will never see it in an access log; disallowing it changes what Google does with content it fetched under a different name.
You are excluded from Gemini grounding and Gemini training. Google Search ranking and indexing are explicitly unaffected. This is the cleanest 'no training, keep my search traffic' lever that exists.
(none: Google-Extended never appears as a user-agent)

A question about this page, answered by a call you can make right now — no key, no account, no JSON-RPC, nothing to assemble. The query string is already filled in with this page's own subject.
curl -s 'https://www.pathwren.workers.dev/tools/verification-methods?crawler=google-extended&s=client-dossiers'
/tools/verification-methods?crawler=google-extendedEvery parameter above is a value the endpoint reads, not an address it visits: nothing is fetched on your behalf. Called without any parameter, each endpoint returns its own specification instead of an error. All of them.
