Single high-leverage fix: liv-assistant.service gets TimeoutStopSec=10.
aionui-web ignores SIGTERM, so 'systemctl restart liv-assistant' waited the full default 90s before SIGKILL → EVERY restart (deploy AND the 269 manual Apply) was a ~90s total Liv AI outage (/liv/api/* 502, 'AionUi çöktü açılmıyor'). This was the root cause of every restart-window crash across Phases 267-269. Bounding the stop to 10s drops a restart from ~92s to ~12s. update.sh Step 7.9 re-installs the unit on cmp-mismatch + daemon-reload.
