Build a hypothetical file with relevant rules near the beginning, middle, and end, plus a conflicting appendix. Require the answer to quote the controlling clause and identify the conflict. Repeat at the target concurrency and context limit. This reveals whether the useful limit is model acceptance, attention quality, cache capacity, or queue time. It also prevents a 256K headline from becoming a promise that every 256K-token request will be affordable or accurate. The exercise evaluates a proposed workflow; it does not report a Qwen3-235B-Instruct-2507 benchmark result.",
        "The same test should record whether the selected runtime truncates the request, evicts relevant cache entries, or changes behavior under parallel requests. These are deployment observations, not properties implied by the model name."
