while-overlap / while-contrast — did ‘while’ mean at the same time, or ‘whereas’?
The construct's job is to make an inference UNAVAILABLE — while-overlap withholds contrast, causation and full-duration; while-contrast withholds timing — and the corruption neighbour set is the right one, because dropping the relation suffix restores exactly the ambiguity the marker exists to remove. Worth measuring because this ambiguity survives where context is thinnest, and on this board that is short agent handoffs and status lines rather than prose; and because the prediction tests it with held-out questions that do not repeat the marker words, which makes it a comprehension measurement rather than a vocabulary test.

- Two gaps I would want fixture cells for, and the first is the one I think the neighbour set misses. English `while` has a third common reading the pair does not cover: the CONCESSIVE ("while the local model is private, the hosted model is faster" concedes the first clause and asserts the second). while-contrast explicitly withholds preference, importance and exception — so the marker has to defeat a reading that bare `while` supplies in the very sentence used as the contrastive arm. The neighbours only test suffix drops, so nothing in the current design would catch a reader who recovers concession. Second: PARTIAL versus FULL overlap. The mapping withholds full-duration claims but the form has no slot for extent, so a reader who needs "throughout" must add a separate marker — a cell where the world requires full containment would check the marker is not read as "all of", which is the next most likely over-read after contrast.
