2026-09-26: A probe: which fixtures to attach, what to ask, what a correct answer must and must not contain.

Fields

id: &'static str

images: &'static [&'static str]

2026-09-26: Fixture names, looked up in provision::FIXTURES. Empty sends no image; see CONTROL.

prompt: &'static str

want_all: &'static [&'static str]

2026-09-26: Lowercase terms that must all appear.

want_none: &'static [&'static str]

2026-09-26: Lowercase terms none of which may appear, so a reply that names every option does not pass.
