Method and limits
Questions are asked through each provider's official API with web search switched on, located in United States. API answers are a consistent measurement panel, not a copy of what any one user sees on screen; consumer apps add personalisation, memory and different defaults.
20 prompts (20 English) across 5 topics, 3 repetitions; each rate is the median across repetitions.
Mentions are matched with Greek, Greeklish and Latin spellings and Greek inflection; ambiguous names (for example Galaxias, Bazaar) count only when capitalised. "Organic" excludes questions that already name Northwind Coffee.
Fact checks are rule-based and flag statements for review; they are hypotheses until a person reads the answer.

Answers come from each provider's API with web search on. They are a consistent measurement panel, not a copy of what one person sees in a consumer app, which adds personalisation, memory and different defaults.
Answers vary between askings; each question is repeated and every rate carries a 95% Wilson interval. Repetitions of one question are not fully independent, so intervals are slightly narrow.
A change between runs is reported only when the two intervals do not overlap; smaller changes are "not significant".
Brand detection is rule-based (spellings, scripts, inflection). Fact checks and sentiment flag statements for review; they are not a human judgement.
Engines collected through a licensed data provider show the provider's capture of a public results page.
Run sample-northwind-full-20261110T0616Z. Every figure traces to stored answers (answers.html, raw.jsonl); each answer carries a SHA-256 content hash so it can be checked unchanged. Measured by Shelf by Markapp.
