What the wide arm ranked its answer from.A scoped read (a context, a cogmap, or a resource bound) scores every resource the scope admits,
so an answer with nothing after it is the whole answer. An unscoped read first draws the nearest
chunks across the corpus and only then applies visibility and doc type, so its answer is bounded
by that draw however short the page is — and unscoped similarity has no membership threshold
that could make it whole.
