sysfacts reads the agent's top-level guest_disk_trim stanza (schedule + per-guest
last attempt: vmid, last_attempt_at, ok, bytes_trimmed, mounts, duration_seconds,
last_ok_at, error) into a field-by-field mirror. The System page's new 'Last disk
trim' column shows the last successful trim and the GiB it freed; amber when the
newest attempt failed (error shown) or last_ok_at is older than 14 days (judged on
the success time, never the attempt time); '—' when the agent sends no stanza.
wire_contract_gate: SUBTREE_MIRRORS checks guest_disk_trim field by field BOTH
ways against sysfacts.DiskTrim; decoys (ok renamed, last_ok_at dropped) in
test_gate_decoys.py. Decision 139.
