The guest's controller asks; the agent refuses in the first 10 min after boot, a second time in
one boot (persisted, keyed by /proc/stat btime), and while a backup, restore test, OS step,
controller update, drive format, NAS verify, escrow ceremony or vzdump runs (each a named 409
reason). On acceptance: the record first, a host report carrying deliberate_off accepted by the
hub (bounded 60 s), then pct shutdown --timeout 120, then systemctl poweroff.
Sudoers: two exact vectors (pct ^shutdown N --timeout N$, systemctl poweroff) in FELHOM_POWEROFF;
nine injection cases. New TestEveryAliasIsGranted: a defined alias missing from the grant line
passed the coverage check before. Every new test red-proofed.
Operator ruling 09 §3 decision 139. One exact sudoers rule FELHOM_FSTRIM
(`/usr/sbin/pct ^fstrim [0-9]+$`) + manifest entry guest-fstrim; new
internal/fstrim job: due Wednesday from 10:00 host-local, starts only
10:00-20:59, holds backup.InFlight (busy -> deferred to the next hourly
tick), failed trim retried at most 3x per week, bytes parsed from the
"(N bytes) trimmed" lines, last result per guest persisted in
<state_dir>/guest-disk-trim.json and reported as guest_disk_trim.
Config opt-out: "disk_trim": {"disable": true}.
